RESUMEN
Sensory Processing Sensitivity (SPS) is a temperament trait rooted in biology, and is distinguished by heightened awareness, emotional responsiveness, and sensitivity to environmental stimuli. In this study, we aimed to enable the assessment of SPS within Spanish-speaking populations. To achieve this, we translated, adapted, and validated the Sensory Processing Sensitivity Questionnaire (SPSQ), which offers a comprehensive evaluation of SPS, encompassing both positive and negative aspects of the trait. Participants were 1,004 (844 females, mean age 37) mainly from Chile (964), and 40 were from other Spanish-speaking regions. Confirmatory factor analysis, utilizing the diagonally weighted least squares method, was applied to validate the internal structure of the Spanish version of the SPSQ (S-SPSQ). Fit indices such as GFI, CFI, TLI, RMSEA, and SRMR were scrutinized. Reliability assessment utilized Cronbach's alpha and McDonald's Omega. Three models were examined: Model I (six factors) displayed robustness, Model II (six factors plus a general factor) did not show substantive improvement, and Model III (Higher Order and Bifactor) excelled in fit while balancing complexity and representation, thus validating the findings of the original SPSQ and indicating similar reliability coefficients. The study offers a balanced perspective on SPS and contributes to cross-cultural validation of an SPS instrument which may facilitate research and guide personalized therapeutic interventions, thus enhancing outcomes for highly sensitive persons.
RESUMEN
Introduction: As captured by the individual trait of Sensory Processing Sensitivity (SPS), highly sensitive children perceive, process, and responds more strongly to stimuli. This increased sensitivity may make more demanding the process of regulating and managing emotions. Yet, developmental psychology literature also showed that other variables, as those related to the rearing environment, are likely to contribute to the process of regulating emotions. With the current contribution, we aim to bridge two lines of research, that of attachment studies and that of SPS, by investigating the additive and interactive contribution of SPS and internal working models of attachment representations on emotion regulation competencies in school-aged children. Method: Participants were N = 118 Italian children (mean age: 6.5, SD = 0.58 years, and 51.8% female) with their mothers. Children's positive attachment representations were rated observationally through the Manchester Child Attachment Story Task procedure during an individual session at school. Mothers reported on children SPS trait and emotion regulation competencies completing the Highly Sensitive Child Scale-parent report and the Emotion Regulation Checklist. We performed and compared a series of main and interaction effect models. Results: SPS was not directly associated with emotion regulation but it was significantly associated with positive attachment representations in predicting emotion regulation. Highly sensitive children showed poorer emotion regulation when the internalized representations were low in maternal warmth and responsiveness. When driven by sensitive and empathic attachment representation, highly sensitive children showed better emotion regulation than less-sensitive peers, suggesting a for better and for worse effect. Discussion: Highly sensitive children are not only more vulnerable to adversities but also show better emotion regulation competencies when supported by positive internal working models of attachment relationships. Overall, findings shed light on the link between SPS and attachment and suggest that working for promoting secure attachment relationships in parent-child dyads may promote better emotion regulation competences, particularly in highly sensitive children.
RESUMEN
Sensory processing sensitivity (SPS) is a biological trait associated with enhanced awareness of and responsivity to the environment, as well as depth of cognitive processing. However, only a few studies have investigated how contextual factors impact cognition as a function of SPS. Thus, this study examined whether SPS is associated with differential changes in cognitive function resulting from participation in a 4-week app-based cognitive training program with neurofeedback (CT-NF). Participants (M age = 66 years) were randomized to either a treatment (CT-NF) or control group (Tetris). They completed a self-report measure of SPS (the Highly Sensitive Person Scale), and cognitive tests at pre- and post-intervention. Results revealed that individuals with higher levels of SPS in the treatment group showed superior improvements in memory (MEM) and visual memory (VSM), relative to other participants and other measures of cognition. These findings are consistent with theories of SPS and studies showing that enhanced visual perceptiveness and memory are associated with the trait. Moreover, they highlight the cognitive mechanisms that might be especially important for SPS. In conclusion, these findings suggest that those with high SPS may experience enhancements in MEM and VSM, resulting from a 4-week app-based CT-NF program.

Sensory processing sensitivity (SPS) is a biological/temperament trait that is associated with greater awareness of and reactivity to the environment, which results in amplified responses to various stimuli, and possibly medications. We investigated the relationship between SPS and medication sensitivity in three studies. Participants (ages 18-81) were recruited from university (Study 1: N = 125; Study 2: N = 214) and online (Study 3: N = 351) samples. In each study, participants completed a medication sensitivity scale, the standard highly sensitive person (HSP) scale to assess SPS, and a negative affectivity (NA) scale as a control variable. All three studies found moderate, significant correlations between SPS and medication sensitivity (r = 0.34, p < 0.001: r = 0.21, p = 0.003; r = 0.36, p < 0.001, respectively). Correlations remained significant, and similar, when controlling for NA and gender; and there were no significant interactions with gender. In sum, our results suggest that SPS is associated with medication sensitivity, even when considering NA and gender. Thus, future work might consider SPS when investigating recommended medication, medication dosage, effectiveness, and adverse drug reactions.
RESUMEN
This study examined the effects of a 4-week cognitive training program with neurofeedback (CT-NF) among 86 healthy adults (M = 66.34 years, range 54-84) randomized to either a treatment (app-based ABC games) or control (Tetris) group. Participants completed seven cognitive assessments, pre- and post-intervention, and measured their cortical brain activity using a XB-01 functional near-infrared spectroscopy (fNIRS) brain sensor, while engaging in CT-NF. The treatment (ABC) group showed significant (pre/post-intervention) improvements in memory (MEM), verbal memory (VBM), and composite cognitive function, while the control group did not. However, both groups showed significant improvements in processing speed (PS) and executive function (EF). In line with other studies, we found that strength of cortical brain activity (measured during CT-NF) was associated with both cognitive (pre and post) and game performance. In sum, our findings suggest that CT-NF and specifically ABC exercises, confer improved cognition in the domains of MEM, VBM, PS, and EF.

The aim of the present study was to investigate (a) the neural correlates of a love induction task (LIT) including listening to love-related songs and thinking about the romantic relationship, and (b) the effects of romantic love on the emotional processing of love-unrelated stimuli during a passive viewing task. The EEG was recorded in two groups of university students: people in love (Love Group, LG, N = 22, 19 F) and people not in love (Control Group, CG, N = 20, 15 F). The LIT induced higher pleasantness and arousal in the LG than in the CG, as well as higher alpha activity in occipital-right electrodes, suggesting active mental imagery and internal focused attention. During the picture viewing task, the LG displayed larger N1 amplitudes than the CG in response to unpleasant pictures, and lower amplitudes of the late positive potential to both pleasant and unpleasant pictures at frontal sites. Overall, these results suggest an early attentional modulation of the neural responses to unpleasant, mood-incongruent cues, followed by an implicit emotional down-regulation of arousing stimuli, which might have important implications for everyday attitudes and behaviors.

BACKGROUND: Sensory processing sensitivity (SPS) is a biologically based temperament trait associated with enhanced awareness and responsivity to environmental and social stimuli. Individuals with high SPS are more affected by their environments, which may result in overarousal, cognitive depletion, and fatigue. METHOD: We examined individual differences in resting-state (rs) brain connectivity (using functional MRI) as a function of SPS among a group of adults (M age = 66.13 ± 11.44 years) immediately after they completed a social affective "empathy" task. SPS was measured with the Highly Sensitive Person (HSP) Scale and correlated with rs brain connectivity. RESULTS: Results showed enhanced rs brain connectivity within the ventral attention, dorsal attention, and limbic networks as a function of greater SPS. Region of interest analyses showed increased rs brain connectivity between the hippocampus and the precuneus (implicated in episodic memory); while weaker connectivity was shown between the amygdala and the periaqueductal gray (important for anxiety), and the hippocampus and insula (implicated in habitual cognitive processing). CONCLUSIONS: The present study showed that SPS is associated with rs brain connectivity implicated in attentional control, consolidation of memory, physiological homeostasis, and deliberative cognition. These results support theories proposing "depth of processing" as a central feature of SPS and highlight the neural processes underlying this cardinal feature of the trait.

In Western culture, romantic love is commonly a basis for marriage. Although it is associated with relationship satisfaction, stability, and individual well-being, many couples experience declines in romantic love. In newlyweds, specifically, changes in love predict marital outcomes. However, the biological mechanisms underlying the critical transition to marriage are unknown. Thus, for the first time, we explored the neural and genetic correlates of romantic love in newlyweds. Nineteen first-time newlyweds were scanned (with functional MRI) while viewing face images of the partner versus a familiar acquaintance, around the time of the wedding (T1) and 1 year after (T2). They also provided saliva samples for genetic analysis (AVPR1a rs3, OXTR rs53576, COMT rs4680, and DRD4-7R), and completed self-report measures of relationship quality including the Eros (romantic love) scale. We hypothesized that romantic love is a developed form of the mammalian drive to find, and keep, preferred mates; and that its maintenance is orchestrated by the brain's reward system. Results showed that, at both time points, romantic love maintenance (Eros difference score: T2-T1) was associated with activation of the dopamine-rich substantia nigra in response to face images of the partner. Interactions with vasopressin, oxytocin, and dopamine genes implicated in pair-bonding (AVPR1a rs3, OXTR rs53576, COMT rs4680, and DRD4-7R) also conferred strong activation in the dopamine-rich ventral tegmental area at both time points. Consistent with work highlighting the role of sexual intimacy in relationships, romantic love maintenance showed correlations in the paracentral lobule (genital region) and cortical areas involved in sensory and cognitive processing (occipital, angular gyrus, insular cortex). These findings suggest that romantic love, and its maintenance, are orchestrated by dopamine-, vasopressin- and oxytocin-rich brain regions, as seen in humans and other monogamous animals. We also provide genetic evidence of polymorphisms associated with oxytocin, vasopressin and dopamine function that affect the propensity to sustain romantic love in early stage marriages. We conclude that romantic love maintenance is part of a broad mammalian strategy for reproduction and long-term attachment that is influenced by basic reward circuitry, complex cognitive processes, and genetic factors.
RESUMEN
INTRODUCTION: In humans, satisfying sexual activity within a pair-bond plays a significant role in relationship quality and maintenance, beyond reproduction. However, the neural and genetic correlates for this basic species-supporting function, in response to a pair-bonded partner, are unknown. METHODS: We examined the neural correlates of oxytocin- (Oxtr rs53576) and vasopressin- (Avpr1a rs3) receptor genotypes with sexual satisfaction and frequency, among a group of individuals in pair-bonds (M relationship length = 4.1 years). Participants were scanned twice (with functional MRI), about 1-year apart, while viewing face images of their spouse and a familiar, neutral acquaintance. RESULTS: Sex satisfaction scores showed significant interactions with Oxtr and Avpr variants associated with social behaviors in a broad network of regions involved in reward and motivation (ventral tegmental area, substantia nigra [SN], and caudate), social bonding (ventral pallidum), emotion and memory (amygdala/hippocampus), hormone control (hypothalamus); and somatosensory and self-other processing (SII, frontal, and temporal lobe). Sexual frequency interactions also showed activations in the SN and paraventricular hypothalamus for Avpr, and the prefrontal cortex for Oxtr. CONCLUSIONS: Satisfying sexual activity in pair-bonds is associated with activation of subcortical structures that support basic motivational and physiological processes; as well as cortical regions that mediate complex thinking, empathy, and self-other processes highlighting the multifaceted role of sex in pair-bonds. Oxtr and Avpr gene variants may further amplify both basic and complex neural processes for pair-bond conservation and well-being.

The present longitudinal study examined the relationship between patterns of cigarette smoking and alcohol use during adolescence and illicit drug abuse (DA) and prescription drug abuse (PDA) in early adulthood. The sample consisted of 984 predominantly minority young adults (57% women) who completed (a) six annual surveys as adolescents attending New York City public schools (grades 7 through 12) and (b) a follow-up telephone interview as young adults (mean age = 23). Findings from a series of latent growth models indicated that growth in cigarette smoking and alcohol use during adolescence each independently predicted DA in adulthood. Baseline levels of alcohol use in 7th grade also predicted DA in adulthood. Growth in alcohol consumption during adolescence predicted PDA in young adulthood. Results indicate that an escalation during adolescence in the use of substances that are legal for adults (cigarettes and alcohol) contributes to greater DA and PDA in young adulthood. One implication of these findings is that interventions that can prevent cigarette smoking and alcohol use during adolescence may also reduce DA and PDA in young adults.

Altruism is an evolutionarily conserved neurobehavioral mechanism for responding to others' needs, even at a cost to the self. It is thought to be rooted in offspring care and is most prominent in kin and close relationships, but also extends to others. We investigated the neural and genetic (OXTR rs53576 and AVPR1a rs3) correlates of altruism (with the Agape scale) in newlywed pair-bonds. Using functional MRI, 18 participants were scanned (T1) while viewing happy or sad face images of the partner; of a stranger; or of a highly familiar, neutral acquaintance (HFN). Thirteen returned for another scan 11 months later (T2), and the additional control of a neutral expression of the partner and stranger was added. At both time points, the right ventral pallidum (VP), ventral tegmental area, and caudate showed significant responses to Partner (romantic) versus HFN images. At T2, altruism scores, OXTR rs53576 G alleles, and AVPR1a rs3 long alleles showed positive correlations with activity in the left VP/accumbens, amygdala, and septum for both Happy and Sad Partner expressions compared to neutral expressions, but not for strangers. However, when the Happy or Sad partner was compared to a Happy or Sad stranger, positive correlations were limited mainly to the amygdala/entorhinal cortex region. This study localized neural correlates of altruism in pair-bonds, including the VP and the amygdala. Also, responsivity in the VP showed increases or decreases as a function of OXTR and AVPR1a variants. These variations may contribute to behavioral heterogeneity and diverse strategies observed in complex social behaviors. In conclusion, the neural and hormonal basis of altruism in pair-bonds may be phylogenetically conserved, yet genetically variable, and promote pair-bond stability and enhance survival and cooperation of the species.

OBJECTIVES: Meditation has been shown to have physical, cognitive, and psychological health benefits that can be used to promote healthy aging. However, the common and specific mechanisms of response remain elusive due to the diverse nature of mind-body practices. METHODS: In this review, we aim to compare the neural circuits implicated in focused-attention meditative practices that focus on present-moment awareness to those involved in active-type meditative practices (e.g., yoga) that combine movement, including chanting, with breath practices and meditation. RECENT FINDINGS: Recent meta-analyses and individual studies demonstrated common brain effects for attention-based meditative practices and active-based meditations in areas involved in reward processing and learning, attention and memory, awareness and sensory integration, and self-referential processing and emotional control, while deactivation was seen in the amygdala, an area implicated in emotion processing. Unique effects for mindfulness practices were found in brain regions involved in body awareness, attention, and the integration of emotion and sensory processing. Effects specific to active-based meditations appeared in brain areas involved in self-control, social cognition, language, speech, tactile stimulation, sensorimotor integration, and motor function. SUMMARY: This review suggests that mind-body practices can target different brain systems that are involved in the regulation of attention, emotional control, mood, and executive cognition that can be used to treat or prevent mood and cognitive disorders of aging, such as depression and caregiver stress, or serve as "brain fitness" exercise. Benefits may include improving brain functional connectivity in brain systems that generally degenerate with Alzheimer's disease, Parkinson's disease, and other aging-related diseases.
RESUMEN
This study explored the relationship between trajectories of affective self-regulation skills during secondary school and young adult substance use in a large multi-ethnic, urban sample (N = 995). During secondary school, participants completed a measure of cognitive and behavioral skills used to control negative, unpleasant emotions or perceived stress. As young adults, participants reported on the frequency and quantity of their alcohol, cigarette, and marijuana use in a telephone interview. Controlling for demographic variables, self-regulation did not significantly change over adolescence, although there was significant variation in participants' rates of growth and decline. Lower seventh grade self-regulation and less steep increases in self-regulation were predictive of higher young adult substance use. Male participants had significantly lower initial self-regulation and higher young adult substance use. The results suggest that interventions that build affective self-regulation skills in adolescence may decrease the risk of young adult substance use.
RESUMEN
BACKGROUND: Theory and research suggest that sensory processing sensitivity (SPS), found in roughly 20% of humans and over 100 other species, is a trait associated with greater sensitivity and responsiveness to the environment and to social stimuli. Self-report studies have shown that high-SPS individuals are strongly affected by others' moods, but no previous study has examined neural systems engaged in response to others' emotions. METHODS: This study examined the neural correlates of SPS (measured by the standard short-form Highly Sensitive Person [HSP] scale) among 18 participants (10 females) while viewing photos of their romantic partners and of strangers displaying positive, negative, or neutral facial expressions. One year apart, 13 of the 18 participants were scanned twice. RESULTS: Across all conditions, HSP scores were associated with increased brain activation of regions involved in attention and action planning (in the cingulate and premotor area [PMA]). For happy and sad photo conditions, SPS was associated with activation of brain regions involved in awareness, integration of sensory information, empathy, and action planning (e.g., cingulate, insula, inferior frontal gyrus [IFG], middle temporal gyrus [MTG], and PMA). CONCLUSIONS: As predicted, for partner images and for happy facial photos, HSP scores were associated with stronger activation of brain regions involved in awareness, empathy, and self-other processing. These results provide evidence that awareness and responsiveness are fundamental features of SPS, and show how the brain may mediate these traits.

The purpose of the present study was to investigate risk and protective factors for intimate partner violence (IPV) victimization in a high-risk sample of predominantly minority young adults from low-income urban communities. Participants were 1,130 individuals (57.9% women) ages 21 to 26 who participated in a telephone interview assessing IPV victimization, violence-related behaviors, and sexual behaviors. Results indicated that about 20.9% of participants reported experiencing one or more IPV incidents in their lifetime. Based on previous research, we examined lifetime violence, lifetime number of sexual partners, number of children, education, and religious service attendance as predictors of IPV. Results from a multivariate logistic regression showed that lifetime violence-related behaviors, number of lifetime sexual partners, and number of children were significant risk factors for IPV. The link between children and IPV risk: (a) was moderated by education for women and men and (b) was stronger for women (vs. men). These findings suggest that training for coping with stress and anger, endorsement of safe sex practices, and greater support for education may be effective strategies for preventing and reducing IPV among high-risk populations.

We explored changes in self-management skills and substance use from 7th to 11th grade in a multiwave study of predominantly minority adolescents (N = 1,756). Using latent growth curve analysis, we found that substance use significantly increased, whereas self-management skills significantly decreased. In a parallel process model, we found that participants who reported higher self-management skills in the 7th grade had smaller increases in substance use. Participants who had larger decreases in self-management skills tended to have greater increases in substance use. We also explored the influence of grades and gender and found that (a) participants with higher grades at baseline had lower initial substance use, higher initial self-management skills, and smaller increases in substance use, and (b) male participants had greater increases in substance use. These results suggest that the provision of self-management skills may be an effective strategy for preventing substance-use initiation and escalation during adolescence.
RESUMEN
The present study examined the neural correlates of long-term intense romantic love using functional magnetic resonance imaging (fMRI). Ten women and 7 men married an average of 21.4 years underwent fMRI while viewing facial images of their partner. Control images included a highly familiar acquaintance; a close, long-term friend; and a low-familiar person. Effects specific to the intensely loved, long-term partner were found in: (i) areas of the dopamine-rich reward and basal ganglia system, such as the ventral tegmental area (VTA) and dorsal striatum, consistent with results from early-stage romantic love studies; and (ii) several regions implicated in maternal attachment, such as the globus pallidus (GP), substantia nigra, Raphe nucleus, thalamus, insular cortex, anterior cingulate and posterior cingulate. Correlations of neural activity in regions of interest with widely used questionnaires showed: (i) VTA and caudate responses correlated with romantic love scores and inclusion of other in the self; (ii) GP responses correlated with friendship-based love scores; (iii) hypothalamus and posterior hippocampus responses correlated with sexual frequency; and (iv) caudate, septum/fornix, posterior cingulate and posterior hippocampus responses correlated with obsession. Overall, results suggest that for some individuals the reward-value associated with a long-term partner may be sustained, similar to new love, but also involves brain systems implicated in attachment and pair-bonding.
