A Randomized Controlled Trial of a Parenting Intervention During Infancy Alters Amygdala-Prefrontal Circuitry in Middle Childhood.

OBJECTIVE: Early adverse parenting predicts various negative outcomes, including psychopathology and altered development. Animal work suggests that adverse parenting might change amygdala-prefrontal cortex (PFC) circuitry, but work in humans remains correlational. The present study leveraged data from a randomized controlled trial examining the efficacy of an early parenting intervention targeting parental nurturance and sensitivity (Attachment and Biobehavioral Catch-up [ABC]) to test whether early parenting quality causally affects amygdala-PFC connectivity later in life. METHOD: Participants (N = 60, mean age = 10.0 years) included 41 high-risk children whose parents were referred by Child Protective Services and randomly assigned to receive either ABC (n = 21) or a control intervention (n = 20) during the children's infancy and a comparison sample of low-risk children (n = 19). Amygdala-PFC connectivity was assessed via functional magnetic resonance imaging while children viewed fearful and neutral faces. RESULTS: Across facial expressions, ABC produced different changes than the control intervention in amygdala-PFC connectivity in response to faces. The ABC group also exhibited greater responses than the control intervention group to faces in areas classically associated with emotion regulation, including the orbitofrontal cortex and right insula. Mediation analysis suggested that the effect of ABC on PFC activation was mediated by the intervention's effect on amygdala-PFC connectivity. CONCLUSION: Results provide preliminary causal evidence for the effect of early parenting intervention on amygdala-PFC connectivity and on PFC responses to face viewing. Findings also highlight amygdala-PFC connectivity as a potential mediator of the effects of early parenting intervention on children's emotion regulation development.

Effects of prenatal opioid exposure on infant sympathetic and parasympathetic nervous system activity.

Prenatal opioid exposure has been associated with developmental problems, including autonomic nervous system dysregulation. However, little is known about the effects of prenatal opioid exposure on the autonomic nervous system beyond the first days of life, particularly across both the parasympathetic and sympathetic branches, and when accounting for exposure to other substances. The present study examined the effects of prenatal exposure to opioid agonist therapy (OAT, e.g., methadone) and other opioids on infant autonomic nervous system activity at rest and in response to a social stressor (the Still-Face Paradigm) at six months among 86 infants varying in prenatal opioid and other substance exposure. Results indicated that OAT and other opioids have unique effects on the developing autonomic nervous system that may further depend on subtype (i.e., methadone versus buprenorphine) and timing in gestation. Results are discussed in the context of theoretical models of the developing stress response system.

Emotion dysregulation and reward responsiveness as predictors of autonomic reactivity to an infant cry task among substance-using pregnant and postpartum women.

Maternal substance use may interfere with optimal parenting, lowering maternal responsiveness during interactions with their children. Previous work has identified maternal autonomic nervous system (ANS) reactivity to parenting-relevant stressors as a promising indicator of real-world parenting behaviors. However, less is known about the extent to which individual differences in emotion dysregulation and reward processing, two mechanisms of substance use, relate to maternal ANS reactivity in substance-using populations. The current study examined associations among emotion dysregulation, reward responsiveness, and ANS reactivity to an infant cry task among 77 low-income and substance-using women who were either pregnant (n = 63) or postpartum (n = 14). Two indicators of ANS functioning were collected during a 9 min computerized infant cry task (Crybaby task): respiratory sinus arrhythmia (RSA) and pre-ejection period. Mothers also completed self-reported measures of emotion dysregulation and reward responsiveness. Analyses revealed that trait emotion regulation was associated with RSA reactivity to the Crybaby task, such that greater emotion dysregulation was associated with greater RSA reduction during the infant cry task than lower emotion dysregulation. Reward responsiveness was not significantly associated with either indicator of ANS reactivity to the task. Findings revealed distinct patterns of associations linking emotion dysregulation with ANS reactivity during a parenting-related computerized task, suggesting that emotion regulation may be a key intervention target for substance-using mothers.

Associations between cortical thickness and parasympathetic nervous system functioning during middle childhood.

Positive associations have been found between cortical thickness and measures of parasympathetic cardiac control (e.g., respiratory sinus arrhythmia, RSA) in adults, which may indicate mechanistic integration between neural and physiological indicators of stress regulation. However, it is unknown when in development this brain-body association arises and whether the direction of association and neuroanatomical localization vary across development. To investigate this, we collected structural magnetic resonance imaging and resting-state respiratory sinus arrhythmia data from children in middle childhood (N = 62, Mage = 10.09, range: 8.28-12.14 years). Whole-brain and exploratory ROI analyses revealed positive associations between RSA and cortical thickness in four frontal and parietal clusters in the left hemisphere and one cluster in the right. Exploratory ROI analyses revealed a similar positive association between cortical thickness and RSA, with two regions surviving multiple comparison correction, including the inferior frontal orbital gyrus and the Sylvian fissure. Prior work has identified these cortical areas as part of the central autonomic network that supports integrative regulation of stress response (e.g., autonomic, endocrine, and behavioral) and emotional expression. Our results suggest that the association between cortical thickness and resting RSA is present in middle childhood and is similar to the associations seen during adulthood. Future studies should investigate associations between RSA and cortical thickness among young children and adolescents.

Social support as a resilience factor for parent-infant dyads experiencing homelessness.

Despite the considerable prevalence of homelessness among very young children in the United States, there is a notable lack of research on risk, resilience, and developmental well-being of infants who experience family homelessness. In the present study, we considered social support as a resilience factor for quality of parent-infant relationships and parent depression among a sample of 106 parents and their infants (ages birth to 12 months) residing in emergency shelters for families experiencing homelessness. We assessed social support, parent histories of adverse experiences during childhood and adulthood, and parent current depression symptoms via structured interview measures, and we assessed quality of the parent-infant relationship with an observational approach. Results showed different patterns for the roles of adversity the parents had experienced during childhood compared to adversity experienced more recently, as adults. Childhood adversity predicted parent-infant responsiveness, with a positive association that was moderated by level of perceived social support. Parents with more childhood adversity showed more responsiveness with their infants only when they had access to high levels of social support. Adulthood adversity predicted higher scores for parent depression, while social support predicted lower parent depression scores. This work contributes to the very limited literature on the functioning of families with infants in shelters. Our discussion includes implications for research, policy, and prevention and intervention efforts. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

A 12-month follow-up of infant neurodevelopmental outcomes of prenatal opioid exposure and polysubstance use.

BACKGROUND: Prenatal opioid exposure has been associated with developmental deficits during infancy, but the literature is limited by simple group comparisons and lack of appropriate controls. Previously published research with the current sample documented unique associations between prenatal opioid exposure and developmental outcomes at three and six months, but less is known about associations later in infancy. METHOD: The current study examined pre- and postnatal opioid and polysubstance exposure as predictors of parent-reported developmental status at 12 months of age. Participants were 85 mother-child dyads, oversampled for mothers taking opioid treatment medications during pregnancy. Maternal opioid and polysubstance use were reported using the Timeline Follow-Back Interview during the third trimester of pregnancy or up to one month postpartum and updated through the child's first year of life. Seventy-eight dyads participated in a 12-month assessment, including 68 with parent-reported developmental status on Ages and Stages Questionnaire. RESULTS: At 12 months, average developmental scores fell within normal ranges and prenatal opioid exposure was not significantly related to any developmental outcomes. However, more prenatal alcohol exposure was significantly related to worse problem-solving scores, and this relationship remained after controlling for adjusted age and other substance exposure. CONCLUSION: Although findings await replication with larger samples and more comprehensive measures, results suggest that unique developmental risks of prenatal opioid exposure may not persist through the first year of life. Effects of prenatal exposure to co-occurring teratogens, such as alcohol, may become apparent as children exposed to opioids develop.

Psychology's Contributions to Anti-Blackness in the United States Within Psychological Research, Criminal Justice, and Mental Health.

The mass incarceration of Black people in the United States is gaining attention as a public-health crisis with extreme mental-health implications. Although it is well documented that historical efforts to oppress and control Black people in the United States helped shape definitions of mental illness and crime, many psychologists are unaware of the ways the field has contributed to the conception and perpetuation of anti-Blackness and, consequently, the mass incarceration of Black people. In this article, we draw from existing theory and empirical evidence to demonstrate historical and contemporary examples of psychology's oppression of Black people through research and clinical practices and consider how this history directly contradicts the American Psychological Association's ethics code. First, we outline how anti-Blackness informed the history of psychological diagnoses and research. Next, we discuss how contemporary systems of forensic practice and police involvement in mental-health-crisis response maintain historical harm. Specific recommendations highlight strategies for interrupting the criminalization of Blackness and offer example steps psychologists can take to redefine psychology's relationship with justice. We conclude by calling on psychologists to recognize their unique power and responsibility to interrupt the criminalization and pathologizing of Blackness as researchers and mental-health providers.

Effects of an attachment-based intervention on autonomic regulation among opioid-exposed infants.

Little is known about whether postnatal intervention enhances autonomic regulation among infants at risk for dysregulation due to prenatal opioid exposure. The present study evaluated the effects of modified Attachment Behavioral Catch-up (mABC) on autonomic regulation for opioid-exposed infants in a pilot randomized clinical trial. We hypothesized that, compared to a control intervention (modified Developmental Education for Families [mDEF]), mABC would be associated with higher resting respiratory sinus arrhythmia (RSA) and pre-ejection period (PEP) as well as greater reactivity to and recovery from a social stressor (Still-Face Paradigm). Pregnant or peripartum women receiving opioid agonist therapy (61 mothers of 64 infants; final N = 36 infants) were randomly assigned to mABC or mDEF, 12-session home visiting programs beginning in the third trimester; mABC targets sensitive parenting, and mDEF targets cognitive and motor development. mABC was associated with significantly greater RSA reactivity and marginally greater PEP reactivity. In models accommodating missing data, mABC was additionally associated with significantly greater RSA recovery. In sensitivity analyses removing siblings, mABC predicted significantly enhanced PEP reactivity. Overall, in these preliminary analyses, mABC was associated with healthier autonomic regulation during a social stressor than mDEF. Thus, mABC may be a promising strategy to promote autonomic regulation among opioid-exposed infants through parenting intervention.

Combating the Conspiracy of Silence: Clinician Recommendations for Talking About Racism-Related Events With Youth of Color.

Graphic videos of race-based violence, including police brutality toward Black people and anti-Asian hate crimes, have exploded over the past year. While documentation of these horrific acts has brought visibility to the pervasiveness of racial discrimination, it has also resulted in youth of color being exposed to racial stressors more than ever before across numerous social media and news platforms.1-3 Beyond the significant race-related stress already experienced by youth in school contexts,4 this increased exposure to racism via media is concerning, as both direct and vicarious exposure to racial discrimination can compromise psychological well-being of youth and cause trauma-like symptoms, such as intrusive thoughts, vigilance, and depression.3,5.

Secure attachment in infancy predicts context-dependent emotion expression in middle childhood.

Attachment security has been linked to healthy socioemotional development, but less is known about how secure attachment in infancy relates to emotional functioning in middle childhood, particularly across multiple contexts. The present study examined associations between secure attachment in infancy and children's context-dependent emotion expression during a parent-child interaction at age 9 (N = 78) among families with Child Protective Services involvement (i.e., children at risk for emotion dysregulation). The results indicated that children classified as securely attached in infancy exhibited less task-incongruent affect (i.e., less positive affect during a distressing discussion, less negative affect during a positive discussion) and a greater decrease in negative affect from a distressing discussion to a positive discussion than children classified as insecurely attached. In addition, secure children were rated as more appropriate in their emotion expression than insecure children. The present study highlights attachment as a promising intervention target for children at risk for emotion dysregulation. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Adapting psychophysiological data collection for COVID-19: The "Virtual Assessment" model.

The COVID-19 pandemic has significantly disrupted research activities globally. Researchers need safe and creative procedures to resume data collection, particularly for projects evaluating infant mental health interventions. Remote research is uniquely challenging for psychophysiological data collection, which typically requires close contact between researchers and participants as well as technical equipment frequently located in laboratory settings. In accordance with public health guidance, we adapted procedures and developed novel protocols for a "virtual assessment" in which women and infants provided behavioral and psychophysiological data from their own homes while researchers coordinated remotely. Data collected at virtual visits included video-recorded parent-child interactions and autonomic nervous system data. Adaptations were designed to optimize safety and data quality while minimizing participant burden. In the current paper, we describe these adaptations and present data evaluating their success across two sites in the United States (University of Delaware and University of Utah), focusing specifically on autonomic nervous system data collected during the well-validated Still-Face Paradigm (SFP). We also discuss advantages and challenges of translating traditional lab procedures into the virtual assessment model. Ultimately, we hope that disseminating these procedures will help other researchers resume safe data collection related to infant mental health during the COVID-19 pandemic and beyond.

La pandemia del COVID-19 ha interrumpido significativamente las actividades de investigación globalmente. Los investigadores necesitan procedimientos seguros y creativos para reasumir la recolección de información, particularmente para proyectos con los que se evalúan intervenciones de salud mental infantil. La investigación remota es particularmente desafiante para recoger información psicofisiológica, lo cual típicamente requiere contacto cercano entre investigadores y participantes, así como también equipo técnico frecuentemente localizado en centros de laboratorio. De acuerdo con las directrices de salud pública, adaptamos procedimientos y desarrollamos protocolos novedosos para una "evaluación virtual," en la cual mujeres e infantes aportaron datos de conducta y psicofisiológicos desde sus propias casas mientras que los investigadores coordinaban remotamente. La información recogida en las visitas virtuales incluyó interacciones progenitor-niño grabadas en video e información del sistema nervioso autónomo. Se diseñaron las adaptaciones para optimizar la seguridad y la calidad de la información mientras que se reducía al mínimo la carga que conlleva la participación. En el presente estudio, describimos estas adaptaciones y presentamos información evaluativa del éxito en dos lugares de Estados Unidos (la Universidad de Delaware y la Universidad de Utah), con enfoque específico en la información obtenida acerca del sistema nervioso autónomo durante el ya bien validado Paradigma del Rostro Inmóvil. Discutimos también las ventajas y retos para transferir los procedimientos tradicionales de laboratorio al modelo de evaluación virtual. En última instancia, esperamos que al diseminar estos procedimientos ayudaremos a otros investigadores a reasumir la segura recolección de información relacionada con la salud mental infantil durante la pandemia del COVID-19 y posteriormente.

La pandémie du COVID-19 a perturbé de manière importante les activités de recherche au niveau global. Les chercheurs ont besoin de procédures sûres et créatives pour reprendre la collecte de données, particulièrement pour des projets évaluant des interventions en santé mentale du nourrisson. Les recherches à distance présentent un défi unique pour la collecte de données psychophysiologiques, qui typiquement exige un contact proche entre les chercheurs et les participants ainsi qu'un équipement technique fréquemment situé en contextes de laboratoire. En accord avec les directives de santé publique nous avons adapté les procédures et développés de nouveaux protocoles pour une « évaluation virtuelle ¼ durant laquelle les femmes et les bébés ont présenté des données comportementales et psychophysiologiques depuis leurs propres domiciles alors que les chercheurs coordonnaient le tout à distance. Les données recueillies durant les visites virtuelles ont inclus des interactions parent-enfant enregistrées à la vidéo et des données liées au système nerveux autonome. Les adaptations ont été conçues afin d'optimiser la sécurité et la qualité des données tout en minimisant le fardeau pour les participants. Dans cet article nous décrivons ces adaptations et présentons les données évaluant leur succès au travers de deux sites aux Etats-Unis (University of Delaware et University of Utah), en s'attachant plus spécifiquement aux données sur le système nerveux autonome obtenues durant le Paradigme de Visage Inexpressif, qui est bien validé. Nous discutons également les avantages et des défis qu'il y a à traduire des procédures traditionnelles de laboratoire en un modèle d'évaluation virtuel. Finalement nous espérons que le fait de disséminer ces procédures aidera d'autres chercheurs à reprendre de manière sûre la collecte de données liées à la santé mentale du nourrisson durant la pandémie du COVID-19 et plus loin.

Infant neurodevelopmental outcomes of prenatal opioid exposure and polysubstance use.

BACKGROUND: Prenatal opioid exposure has been linked to adverse birth outcomes and delays in infant development. Existing literature is limited by a simple group-differences approach as well as inadequate controls for sociodemographic factors and polysubstance exposure co-occurring with prenatal opioid use. METHOD: The current study assessed cumulative opioid exposure (duration of prescribed and illicit opioid use) as a predictor of infant birth outcomes and mother-reported developmental status at three and six months of age, controlling for polysubstance exposure. Participants were predominantly low-income pregnant and peripartum women, oversampled for mothers receiving medication-assisted treatment (MAT) for opioid use disorder. Prenatal opioid and non-opioid substance use were reported by mothers using a Timeline Follow-Back Interview completed during the third trimester and updated postnatally (infant age six months). RESULTS: Developmental scores were in the normal range. However, total opioid exposure was positively related to premature birth and inversely related to mother-reported developmental status in specific domains. Associations with three-month fine motor skills and six-month communication skills were robust to controls for polysubstance exposure and sociodemographic covariates. CONCLUSIONS: Results suggest unique effects of prenatal opioid exposure on the early development of fine motor and communication skills. Similar findings were obtained for prescribed and illicit opioid use, underscoring developmental risks of both MAT and untreated substance use. Exploratory analyses investigating type and timing of MAT suggest directions for future research.

Increasing secure base script knowledge among parents with Attachment and Biobehavioral Catch-up.

This study evaluated whether Attachment and Biobehavioral Catch-up (ABC), a parenting intervention, altered the attachment representations of parents (average age of 34.2 years) who had been referred to Child Protective Services (CPS) due to risk for child maltreatment when their children were infants. Approximately 7 years after completing the intervention, parents who had been randomized to receive ABC (n = 43) exhibited greater secure base script knowledge than parents who had been randomized to receive a control intervention (n = 51). Low-risk parents (n = 79) exhibited greater secure base script knowledge than CPS-referred parents who had received a control intervention. However, levels of secure base script knowledge did not differ between low-risk parents and CPS-referred parents who had received the ABC intervention. In addition, secure base script knowledge was positively associated with parental sensitivity during interactions with their 8-year-old children among low-risk and CPS-referred parents. Mediational analyses supported the idea that the ABC intervention enhanced parents' sensitivity 7 years later indirectly via increases in parents' secure base script knowledge.

Respiratory sinus arrhythmia as a moderator of early maltreatment effects on later externalizing problems.

Physiological regulation may interact with early experiences such as maltreatment to increase risk for behavior problems. In the current study, we investigate the role of parasympathetic nervous system regulation (respiratory sinus arrhythmia [RSA] at rest and in response to a frustration task) as a moderator of the association between early risk for maltreatment (i.e., involvement with Child Protective Services; CPS) and externalizing behavior problems in middle childhood. CPS involvement was associated with elevated externalizing problems, but only among children with average to high RSA at rest and average to high RSA withdrawal in response to frustration. Effects appeared to be specific to CPS involvement as the association between cumulative risk (i.e., nonmaltreatment experiences of early adversity) and externalizing problems was not significantly moderated by RSA activity. These findings are consistent with the theoretical idea that the consequences of early maltreatment for later externalizing behavior problems depend on children's biological regulation abilities.

Attachment security in infancy predicts reduced parasympathetic reactivity in middle childhood.

Children with histories of secure attachments during infancy are expected to develop healthier patterns of physiological activity at rest and in response to a stressor than children with insecure attachments. The present study examined longitudinal associations between infant attachment security and children's respiratory sinus arrhythmia (RSA) at rest and in response to a frustration task at age 9. The study focused on a sample of children referred from Child Protective Services (N = 97). RSA reflects the regulation of the parasympathetic branch of the autonomic nervous system, is sensitive to environmental influences, and is associated with emotion regulation. Children with histories of secure attachments during infancy exhibited less RSA withdrawal during a frustration task than children with histories of insecure attachments. Attachment security was not significantly associated with baseline RSA. Results suggest that mitigating parasympathetic reactivity during frustrating situations may be one avenue by which infant attachment security promotes emotion regulation.

Early parenting intervention accelerates inhibitory control development among CPS-involved children in middle childhood: A randomized clinical trial.

Children at risk for neglect or abuse are vulnerable to delays in inhibitory control development. Prior findings suggest that early parenting interventions that target parental sensitivity and responsiveness during infancy can improve executive function outcomes of high-risk children during preschool years; however, little is known about how persistent these gains are through middle childhood. Participants included 76 CPS-involved children who were randomly assigned to either the ABC intervention (N = 32) or the Developmental Education for Families (DEF) control intervention (N = 44), and 53 low-risk children. Children completed the Stop Signal Reaction Time (SSRT) paradigm at ages 8 and 10. Intervention group predicted performance on the SSRT at age 8 such that children who received the ABC intervention and children in the low-risk group performed significantly better than children who received the DEF intervention (ABC vs. DEF: Cohen's d = 0.92; low-risk group vs. DEF: d = 0.56). The performances of the ABC and the low-risk groups were not statistically different. There were no significant group differences in SSRT performance at age 10. These findings demonstrate that the ABC intervention has long-term beneficial effects on inhibitory control development in children with a history of early caregiving adversity.

Early Parenting Intervention Effects on Brain Responses to Maternal Cues Among High-Risk Children.

OBJECTIVE: Early adversity is correlated with increased risk for negative outcomes, including psychopathology and atypical neurodevelopment. The authors aimed to test the causal impact of an early parenting intervention (Attachment and Biobehavioral Catch-Up; ABC) on children's neural processing of parent cues and on psychosocial functioning in a longitudinal randomized clinical trial. METHODS: Participants (N=68, mean age, 10.0 years [SD=0.8 years]) were 46 high-risk children whose parents were randomly assigned to receive either the ABC intervention (N=22) or a control intervention (N=24) while the children were infants, in addition to a comparison sample of low-risk children (N=22). During functional MRI scanning, children viewed pictures of their own mothers and of a stranger. RESULTS: Children in the ABC condition showed greater maternal cue-related activation than children in the control condition in clusters of brain regions, including the precuneus, the cingulate gyrus, and the hippocampus, regions commonly associated with social cognition. Additionally, greater activity in these regions was associated with fewer total behavior problems. There was an indirect effect of early intervention on middle childhood psychosocial functioning mediated through increased activity in brain regions in response to maternal cues. CONCLUSIONS: These results suggest that early parenting intervention (in this case the ABC intervention) can enhance brain regions supporting children's social cognitive development. In addition, the findings highlight these brain effects as a possible neural pathway through which ABC may prevent future behavior problems among high-risk children, yielding psychosocial benefits that endure through at least middle childhood without the need to intervene with the child directly.

Evidence Base Update for Brief, Free, and Accessible Youth Mental Health Measures.

Evidence-based assessment (EBA) is foundational to high-quality mental health care for youth and is a critical component of evidence-based practice delivery, yet is underused in the community. Administration time and measure cost are barriers to use; thus, identifying and disseminating brief, free, and accessible measures are critical. This Evidence Base Update evaluates the empirical literature for brief, free, and accessible measures with psychometric support to inform research and practice with youth. A systematic review using PubMed and PsycINFO identified measures in the following domains: overall mental health, anxiety, depression, disruptive behavior, traumatic stress, disordered eating, suicidality, bipolar/mania, psychosis, and substance use. To be eligible for inclusion, measures needed to be brief (50 items or less), free, accessible, and have psychometric support for their use with youth. Eligible measures were evaluated using adapted criteria established by De Los Reyes and Langer (2018) and were classified as having excellent, good, or adequate psychometric properties. A total of 672 measures were identified; 95 (14%) met inclusion criteria. Of those, 21 (22%) were "excellent," 34 (36%) were "good," and 40 (42%) were "adequate." Few measures had support for their use to routinely monitor progress in therapy. Few measures with excellent psychometric support were identified for disordered eating, suicidality, psychosis, and substance use. Future research should evaluate existing measures for use with routine progress monitoring and ease of implementation in community settings. Measure development is needed for disordered eating, suicidality, psychosis, and substance use to increase availability of brief, free, accessible, and validated measures.

Effects of an attachment-based intervention in infancy on children's autonomic regulation during middle childhood.

The present study used a longitudinal randomized clinical trial to test whether an early intervention has causal effects on children's autonomic nervous system regulation. When children were infants, parents involved with Child Protective Services received Attachment and Biobehavioral Catch-up (ABC; N = 43), an intervention that promotes sensitive parenting, or a control intervention (N = 53). When children were 9 years old, children whose parents had received ABC exhibited higher respiratory sinus arrhythmia and lower heart rate at rest and during a parent-child interaction than children in the control group. Intervention effects were not detected for children's average skin conductance levels or for indices of autonomic reactivity. Results suggest that a parenting-focused early intervention impacted the development of children's autonomic regulation.

Perceptual Encoding in Auditory Brainstem Responses: Effects of Stimulus Frequency.

Purpose: A central question about auditory perception concerns how acoustic information is represented at different stages of processing. The auditory brainstem response (ABR) provides a potentially useful index of the earliest stages of this process. However, it is unclear how basic acoustic characteristics (e.g., differences in tones spanning a wide range of frequencies) are indexed by ABR components. This study addresses this by investigating how ABR amplitude and latency track stimulus frequency for tones ranging from 250 to 8000 Hz. Method: In a repeated-measures experimental design, listeners were presented with brief tones (250, 500, 1000, 2000, 4000, and 8000 Hz) in random order while electroencephalography was recorded. ABR latencies and amplitudes for Wave V (6-9 ms) and in the time window following the Wave V peak (labeled as Wave VI; 9-12 ms) were measured. Results: Wave V latency decreased with increasing frequency, replicating previous work. In addition, Waves V and VI amplitudes tracked differences in tone frequency, with a nonlinear response from 250 to 8000 Hz and a clear log-linear response to tones from 500 to 8000 Hz. Conclusions: Results demonstrate that the ABR provides a useful measure of early perceptual encoding for stimuli varying in frequency and that the tonotopic organization of the auditory system is preserved at this stage of processing for stimuli from 500 to 8000 Hz. Such a measure may serve as a useful clinical tool for evaluating a listener's ability to encode specific frequencies in sounds. Supplemental Material: https://doi.org/10.23641/asha.6987422.
