RESUMEN
El presente estudio investigó si la satisfacción con la vida se predice a partir de la felicidad subjetiva, afectos positivos y negativos, alteración psicológica y emociones de gratitud y si la emoción de gratitud está mediando la relación con la felicidad subjetiva, los afectos y la satisfacción con la vida. Se hicieron correlación de Pearson, pruebas de regresión lineal múltiple y modelos de mediación en una muestra de 1537 adultos españoles, 73.6% mujeres y 26.4% hombres, edad 18-88 años (M = 42.56 años; DT = 16.29). Se halló que las emociones de gratitud median la relación entre felicidad subjetiva y satisfacción con la vida y entre los afectos positivos y la satisfacción con la vida. Los afectos positivos son los que más se relacionan con la satisfacción con la vida, seguidos por la felicidad subjetiva y las emociones de gratitud. Los hombres están más satisfechos con la vida cuando sienten menos afecto negativo. Además, las emociones de gratitud median la relación entre felicidad subjetiva y satisfacción con la vida y entre los afectos positivos y la satisfacción con la vida. La diferencia principal radica en que las emociones de gratitud son más fuertes en las mujeres que en los hombres.(AU)
This study aims to examine the predictability of satisfaction with life on the basis of subjective happiness, positive and negative affect, psy-chological disturbance and emotion of gratitude. It also seeks to assess whether the emotion of gratitude is a mediating variable withsubjective happiness, affect, and satisfaction with life. Statistical analyses of Pearson'scorrelation, multiple linear regression tests, and mediation models were conducted on asample of 1537 Spanish adults, 73.6% were females, 26.4% males, age between 18-88 yearsold (M = 42.56; SD = 16.29). The emo-tions of gratitude were found to mediate therelationship between subjec-tive happiness and satisfaction with life and between positiveaffect and satisfaction with life. Of the variables studied, positive affect is the most related tosatisfaction with life, followed by subjective happiness and emo-tions of gratitude. Maleparticipants are more satisfied with life when they feel the less negative affect. Regardingmediation models, emotions of grat-itude mediate the relationship between subjectivehappiness and satisfac-tion with life and between positive affect and satisfaction with life. Themaindifferenceis thatemotions of gratitudearestronger infemalesthan in males.(AU)

Males and females have long shown disparities in body weight and height; yet, the underlying mechanisms influencing growth and development remain unclear. Male and female Zhedong White Geese (ZDW) geese have long been selected for large body size and egg production, respectively. This led to a large difference in body weight between males and females, making them a unique model for studying the effects of sex on growth and development. This study aimed to elucidate these mechanisms by comparing the transcriptomes of muscle and pituitary tissues in male and female ZDW geese to identify the critical genes responsible for the effects of sex on growth performance. Our analysis revealed 1101 differentially expressed genes (DEGs) in leg musculature (507 upregulated, 594 downregulated), 773 DEGs in breast musculature (311 upregulated, 462 downregulated), and 517 DEGs in the pituitary gland (281 upregulated, 236 downregulated) between male and female geese. These DEGs were significantly enriched in gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways associated with endocrine metabolism (e.g., hormonal activities), muscle formation (e.g., sarcomere and myofibril), and bone formation (e.g., bone morphogenesis and cartilage formation). The upregulated genes in males were enriched in KEGG pathways involving nutrient digestion and absorption (vitamin and protein), as well as the secretion of digestive juices (gastric acid and bile). Through protein-protein interaction analyses, we also observed high-density gene networks related to muscle fiber development, calcium ion metabolism, mitochondrial respiratory chain, and bone development. Therefore, our multi-tissue transcriptome analysis provides a deeper understanding of the complex and systematic gender-driven effects on growth and development in geese. IGF1, GHRHR, and NCAPG-LCORL and pathways related to myogenesis might play vital roles in gender differences before hormones exert their effect.

The transcription factor MYC is overexpressed in many human cancers and has a significant causal role in tumor incidence and progression. In contrast, Myc +/- heterozygous mice, which have decreased MYC expression, exhibit a 10-20% increase in lifespan and a decreased incidence or progression of several age-related diseases. Myc heterozygous mice were also reported to have decreased mTOR and IGF1 signaling, two pathways whose reduced activity is associated with longevity in diverse species. Given MYC's downstream role in these pathways, the downregulation of mTOR and IGF1 signaling in Myc heterozygotes suggests the presence of feedback loops within this regulatory network. In this communication we provide further evidence that the reduction of Myc expression in Myc +/- heterozygous mice provokes a female-specific decrease in circulating IGF1 as well as a reduction of IGF1 protein in the liver. In particular, reduced Myc expression led to upregulation of miRNAs that target the Igf1 transcript, thereby inhibiting its translation and leading to decreased IGF1 protein levels. Using Argonaute (AGO)-CLIP-sequencing we found enrichment of AGO binding in the Igf1 transcript at the target sites of let-7, miR-122, and miR-29 in female, but not male Myc heterozygotes. Upregulation of the liver-specific miR-122 in primary hepatocytes in culture and in vivo in mice resulted in significant downregulation of IGF1 protein, but not mRNA. Reduced levels of IGF1 increased GH production in the pituitary through a well-documented negative-feedback relationship. In line with this, we found that IGF1 levels in bone (where miR-122 is not expressed) were unchanged, consistent with the decreased incidence of osteoporosis in female Myc heterozygotes, despite decreased circulating IGF1.
RESUMEN
The purpose of the present study was to profile bullying behaviors in elementary schools in Saudi Arabia. A secondary purpose was to examine differences in bullying behaviors across gender. Participants were 3867 fourth graders who completed surveys during the TIMSS 2019 survey. An 11-item bullying experience scale was utilized with good internal consistency reliability. Data were analyzed using latent class analysis with Mplus 8.9 to identify profiles of bullying experiences. The results indicated the presence of five profiles with levels of low, medium, and high bullying experiences, as well as two profiles with no cyberbullying experiences and medium high and medium low physical and verbal instances of bullying. Gender effects were highly pronounced, with most maladaptive bullying profiles being predominantly male. It is concluded that physical bullying is mainly occupied by males and the levels of cyberbullying are generally low in the elementary school grades. Implications for educational policy can clearly direct the development of support groups and expert counseling for both bullies and victims, staff training for identification and course of action, and the development of standardized school policies when such incidences occur.
RESUMEN
PURPOSE: The current study aims to evaluate gender variations in the efferent auditory system functioning in the ANSD population and compare them to normal hearing persons using contralateral suppression of spontaneous OAE (SOAEs). METHODS: For the current study, a total of 54 ears were considered prospectively. 27 ears with normal hearing (NH) sensitivity were in group I, while 27 ears with ANSD were in group II. All of the subjects had a regular audiological examination followed by synchronised SOAE recordings with and without broadband noise (in the contralateral ear) at 50 dB SPL and statistical analysis was carried out. RESULTS: Wilcoxon signed rank test revealed a significant decrease in SOAE amplitude with contralateral noise stimulation in NH, while no such trend was observed in ANSD. However, contralateral SOAE stimulation resulted in significant high-frequency shifts for both the ANSD and NH groups in the noise condition. In the comparison of gender effects on SOAE amplitude and frequency shifts using Mann-Whitney, no significant gender differences were seen. The lack of gender differences in SOAE suppression is explained based on global standing wave theory and local oscillator theory. CONCLUSIONS: Contralateral effect of noise on SOAE shows frequency shifts, but not amplitude shifts both of which are not affected by gender effects.

BACKGROUND: Unmanned aerial vehicles (UAVs) or drones are becoming popular in both commerce and private usage. Behaviors of novice drone operators are critical to UAV flight safety. OBJECTIVES: This study aims at discovering the perceived difficulty, flight information access frequency, and flight performance of novice drone operators. METHODS: Twenty adults without prior experience joined as human participants. After attending an onsite training, they operated a drone to perform three missions. The subjective rating of mission difficulty, frequency of flight information checked, and time to complete the mission were analysed. RESULTS: The results indicated significance of gender effects on the difficulty experienced by the novices. Females reported significantly higher difficulty ratings than males initially. This gender difference diminished later in their last mission. Frequency of flight information access was negatively correlated with the difficulty experienced by the operators. Operators who checked flight information more often had less difficulty in performing the flight missions. CONCLUSIONS: There were gender effects in the perceived difficulty and flight information access in drone operations for novices. Such information is helpful in drone operator training and drone design considering drone operation safety.

The impostor phenomenon (IP) refers to the tendency to perceive oneself as intellectually incompetent and to attribute one's own success to effort-related or external factors, such as fortunate circumstances. The present study (N=209) aimed to contribute to open questions regarding gender differences in the IP and the nomological network of the IP. The results show that the consistently found key correlates of the IP, that is, lower self-esteem and higher neuroticism, could also play a role in explaining why women report higher impostor feelings than men in many studies. Moreover, the results suggest that IP is characterized by the more maladaptive, socially prescribed perfectionism, which is related to the belief that others expect perfection from oneself, whereas self-oriented perfectionism, which is characterized by a critical view on oneself, plays a smaller role in differences in the IP. Finally, a strong association with the sandbagging construct challenges the conceptualization of the IP as a genuine doubt about one's own competence, because similarly to IP, sandbaggers present themselves negatively to others, but do so for very strategic reasons in order to create a low expectation base in other individuals. Regression analysis was used to assess the incremental value of the personality factors in explaining variance in the IP. It was found that sandbagging and IP are highly related but not interchangeable.
RESUMEN
BACKGROUND: Depressive symptoms are known to affect memory efficiency in various populations. More specifically, several studies conducted in patients suffering from schizophrenia have indicated that memory efficiency is affected by depressed mood in female patients and by anxiety in male patients. We investigated, using neuroimaging techniques, whether similar gender-specific associations with subclinical depression and anxiety could be observed in a non-clinical sample. METHOD: Forty-five healthy Spanish-speaking individuals (23 females) were administered a verbal memory task. Lists of high- and low-frequency words were presented. Immediate free recall was requested after the learning of each list, and a yes/no recognition task was completed during the acquisition of the fMRI data. RESULTS: Regression analyses revealed that higher depression scores in women, and higher anxiety scores in men, were associated with poorer recall. In women, higher depression scores were further associated with decreased cerebral activity in the right temporoparietal junction, left inferior occipitotemporal gyrus, bilateral thalamus, and left anterior cingulate during correct recognition of target words. In men, anxiety scores were not associated with any cerebral activity. CONCLUSIONS: Subclinical depression in women appears to affect memory efficiency by impacting cerebral regions specifically recruited for the cognitive demands of the task, as well as cerebral regions more generally involved in arousal, decision-making, and emotional regulation. Anxiety in men might impact the encoding memory processes. The results, although preliminary, suggest that gender differences may need to be taken into account when developing strategies for the cognitive and pharmacological remediation of memory impairment.

Pupillary alterations in virtual humans induce neurophysiological responses within an observer. Technological advances have enabled rapid developments in artificial intelligence (AI), from verbal systems, to visual AI interfaces with the ability to express, and respond to emotional states of a user. Visual AI interfaces are able to change their physical parameters, such as pupil diameter. Pupillary changes can alter heart rate, however, effects on heart rate variability (HRV) are unknown. HRV, is an autonomic, non-conscious parameter which monitors sympathetic and parasympathetic nervous system (PNS) activity. N = 34 male participants aged between 19-33 were subjected to a number of conditions such as pupil dilation, constriction and blushing. The present research is the first to investigate the effects of virtual human interactions on human HRV. Outcomes of this study were obtained using eye tracking and HRV measurements. Pupil dilation relative to constriction presented in the female virtual partner induced a significant right pupillary diameter increase (p = 0.041) in human observers. Additionally, female virtual partner pupil constriction relative to dilation induced a significant increase in participants' PNS HRV response (p = 0.036). These findings indicate the ability of a female virtual interaction partner to modulate parasympathetic autonomic functioning in young healthy male humans. This allows first insights into the effects of interacting with virtual AI interaction partners, on human autonomic functioning, and may aid development of future virtual humans, and their implementation into relevant clinical settings.

In recent years, there has been growing interest in examining the stimulus pull effects on respondent narratives to the Thematic Apperception Test (Murray, 1943) using standardized coding methods such as the Social Cognition and Object Relations Scale-Global Rating Method (SCORS-G; Stein, Hilsenroth, Slavin-Mulford, & Pinsker, 2011; Westen, 1995). The present study expands on prior work by examining sources of variance in SCORS-G dimensions and card pull effect patterns in an adult clinical sample characterized by high psychiatric comorbidity and clinical severity. A sample of 158 adult psychiatric patients in long-term residential treatment provided narratives to 10 TAT cards (five of which have not previously been studied for pull effects). Cards 2 and 7BM pulled for significantly more adaptive narratives (positive pull), whereas Card 13MF pulled for more pathological stories (negative pull). Like prior studies, variance in cognitive dimensions of the SCORS-G was most explained by person effects, whereas the largest source of variance for all other dimensions was best explained by a combination of the card and the person effects on the narrative. Finally, exploratory analyses of card pull effects within different gender groups were conducted. The implications of these findings for performance-based future studies and possible clinical applications of card pull findings are discussed.

BACKGROUND: The literature emphasizes the importance of matching the demand and supply of endocrinology and metabolism (EM) specialists. This study analyzed the current status of EM specialists in Taiwan. The gender effects on the workplace of EM specialists were also evaluated. METHODS: The number of internal medicine (IM) specialists was obtained from the websites of the Ministry of Health and Welfare. Data about EM specialists were retrieved from the database of the Endocrine Society of the Republic of China (ESROC; Taiwan). Differences in age distribution and workplace levels or locations between female and male EM specialists were analyzed. RESULTS: Since 1988, 809 physicians were certified as EM specialists. The average age of 739 EM specialists (509 male, 230 female) who remained as active members of the ESROC was 49.9 ± 11.1 years. The age distribution (p < 0.001) and workplace location (p = 0.043) were significantly different between male and female EM specialists. Divided by decades, the ratio of female-to-male EM specialists revealed an increasing tendency (p < 0.001). The percentage of EM specialists among IM specialists, certified 2 years previously, declined from 14.0% in 2017 to 7.9% and 8.3% in 2018 and 2019, respectively. CONCLUSION: The female-to-male ratio of EM specialists increased gradually. Compared to males, female EM specialists were relatively younger, and more of them had clinical practice in northern Taiwan. The percentage of IM specialists becoming EM specialists declined in the last 2 years. The equilibrium between the supply and demand of EM specialists deserves further investigation.

OBJECTIVES: The purposes of this study were to explore gender differences in condom purchasing from condom-vending machines (CVMs) and identify ways to improve CVM promotion. METHODS: Semi-structured interviews with 42 men and women aged 18-50 years (mean ± standard deviation, 29.1 ± 7.9) and living in or near Florence, Italy, were conducted between May and June 2019. Techniques from expanded grounded theory-guided data analysis allowed for a constant comparative approach to contextualise data and identify emergent themes. RESULTS: Three themes emerged: (1) attitudes and barriers towards CVMs; (2) gender-specific purchasing influences and behaviours; and (3) CVM improvement and promotion. Women and men described varied concerns surrounding CVM purchasing, illuminating reasons for hesitancy. Focussing on CVM quality and improving product offerings were suggested by participants to increase use. CONCLUSION: Findings offer practical recommendations to guide CVM messaging to increase access to and use of condoms and other personal care items. Men were cited as primary CVM users, expressing practical concerns surrounding CVMs, while, for women, CVM visibility was as much an advantage as a drawback. Reflecting consumer needs via diversified product offerings should be considered a priority for increased CVM use. Working to promote CVMs requires clear messaging that attends to gender norm limitations, details product safety and establishes CVMs as a reliable condom purchase outlet.

BACKGROUND: Diminished balance confidence increases the risk of a fall and falls that occur when turning during walking are associated with an eightfold increase in hip fractures compared to when walking in a straight trajectory. Although an effect of aging on turning is revealed, the role of gender during turning is not yet clear. RESEARCH QUESTION: How can balance confidence impact turning behavior in younger, middle-aged, and older men and women? METHODS: This cross-sectional study included 22 young adults (11 women), 13 middle-aged adults (9 women), and 13 older adults (6 women). Participants ranked their balance confidence using the activities-specific balance confidence (ABC) scale and completed two different turns: Turn1 (around the cone) and Turn2 (turn to sit). Measures obtained for each turn included: turning time, step count, and peak trunk velocities (PTV) in pitch, yaw, and roll. RESULTS: In Turn1, older adults exhibited an increase in turning time and step count relative to younger adults (both p < 0.03). In Turn2, older adults showed an increase in turning time and roll PTV compared to the middle-aged group (both p < 0.02). Lower scores in ABC were significantly correlated with an increase in Turn1 time (p < 0.001) and step count (p = 0.04) in middle-aged and older adults, respectively. Bivariate correlations revealed that women with lower scores on the ABC took more time to complete both turns (both p = 0.01). SIGNIFICANCE: Older adults demonstrated longer turning time, more steps, and higher roll PTV while turning that were associated with decreased balance confidence scores. The association between decreased balance confidence and turning kinematics implies a relationship between turning and increased fall risk. These results suggest that testing for fall risk requires tests of activities that are performed outside traditional clinical settings and gait laboratories.

OBJECTIVE: The number of women veterans seeking Veterans Health Administration services has substantially increased over the past decade. Neuropsychology remains an understudied area in the examination of gender differences. The present study sought to delineate similarities and differences in men and women veterans presenting for neuropsychological evaluation in terms of demographics, referral, medical conditions, effort, and outcome diagnosis. METHOD: A database collected from an outpatient VA neuropsychology clinic from 2013 to 2019 was analyzed (n = 232 women, 2642 men). Additional analyses examined younger (n = 836 men, 155 women) and older (n = 1805 men, 77 women) age cohorts. RESULTS: Women veterans were younger and more educated than men, whereas men had higher prevalence of vascular risk factors. Both groups were most often referred from mental health clinics and memory was the most common referral question. Although men performed worse on performance validity measures, clinicians rated women as evidencing poorer effort on a cumulative rating based on formal and embedded performance validity measures, behavioral observations, and inconsistent test patterns. Older women reported more depressive symptoms than older men and were more commonly diagnosed with depression. CONCLUSIONS: This exploratory study fills a gap in the understanding of gender differences in veterans presenting for neuropsychological evaluations. Findings emphasize consideration for the intersection of gender with demographics, medical factors, effort, and psychological symptoms by VA neuropsychologists. A better understanding of relationships between gender and these factors may inform neuropsychologists' test selection, interpretation of behavioral observations, and diagnostic considerations to best treat women veterans.

PURPOSE: Patients with advanced cancer often receive suboptimal end-of-life (EOL) care. Particularly males with advanced cancer are more likely to receive EOL care that is more aggressive, even if death is imminent. Critical factors determining EOL care are EOL conversations or advance care planning. However, information about gender-related factors influencing EOL conversations is lacking. Therefore, the current study investigates gender differences concerning the content, the desired time point, and the mode of initiation of EOL conversations in cancer patients. METHODS: In a cross-sectional study, 186 female and male cancer patients were asked about their preferences for EOL discussions using a semi-structured interview, focusing on (a) the importance of six different topics (medical and nursing care, organizational, emotional, social, and spiritual/religious aspects), (b) the desired time point, and (c) the mode of discussion initiation. RESULTS: The importance of EOL topics differs significantly regarding issue (p = 0.002, η2 = 0.02) and gender (p < 0.001, η2 = 0.11). Males wish to avoid the engagement in discussions about death and dying particularly if they are anxious about their end-of-life period. They wish to be addressed regarding the "hard facts" nursing and medical care only. In contrast, females prefer to speak more about "soft facts" and to be addressed about each EOL topic. Independent of gender, the majority of patients prefer to talk rather late: when the disease is getting worse (58%), at the end of their therapy, or when loosing self-sufficiency (27.5%). CONCLUSION: The tendency of patients to talk late about EOL issues increases the risk of delayed or missed EOL conversations, which may be due to a knowledge gap regarding the possibility of disease-associated incapability. Furthermore, there are significant gender differences influencing the access to EOL conversations. Therefore, for daily clinical routine, we suggest an early two-step, gender-sensitive approach to end-of-life conversations.

Patterns in resting-state fMRI (rs-fMRI) are widely used to characterize the trait effects of brain function. In this aspect, multiple rs-fMRI scans from single subjects can provide interesting clues about the rs-fMRI patterns, though scan-to-scan variability pose challenges. Therefore, rs-fMRI's are either concatenated or the functional connectivity is averaged. This leads to loss of information. Here, we use an alternative way to extract the rs-fMRI features that are common across all the scans by applying common-and-orthogonal-basis-extraction (COBE) technique. To address this, we employed rs-fMRI of 788 subjects from the human connectome project and estimated the common-COBE-component of each subject from the four rs-fMRI runs. Since the common-COBE-component is specific to a subject, the pattern was used to classify the subjects based on the similarity/dissimilarity of the features. The subset of subjects (n = 107) with maximal-COBE-dissimilarity (MCD) was extracted and the remaining subjects (n = 681) formed the COBE-similarity (CS) group. The distribution of weights of the common-COBE-component for the two groups across rs-fMRI networks and subcortical regions was evaluated. We found the weights in the default mode network to be lower in the MCD compared to the CS. We compared the scores of 69 behavioral measures and found six behaviors related to the use of marijuana, illicit drugs, alcohol, and tobacco; and including a measure of antisocial personality to differentiate the two groups. Gender differences were also significant. Altogether the findings suggested that subtypes exist even in healthy control population, and comparison studies (case vs. control) need to be mindful of it.

OBJECTIVE: Irritable bowel syndrome (IBS) is a functional disorder with a complex biopsychosocial etiopathogenesis. Various psychosocial factors like adverse childhood experiences (ACE) and illness anxiety appear to be relevant, but underlying mechanisms are still not fully understood. Furthermore, there are indicators of gender specific effects of ACE on IBS. Therefore, this study analyzed group differences between IBS patients and healthy controls (HCs) according to ACE and illness anxiety, and the relationship between ACE and illness anxiety by taking gender differences into consideration. METHODS: A cross-sectional multi-center study was conducted comparing IBS patients with HCs. Illness anxiety was recorded using the Whiteley-Index-7, childhood adversities via the 10-item Adverse-Childhood-Experiences-score, anxiety by the Generalized Anxiety Disorder seven-item questionnaire and depressive symptoms using the nine-item depression module of the patient-health-questionnaire. Group differences between IBS patients and HCs were analyzed and correlation analyses were performed. RESULTS: Overall, 127 gender and education matched participants per group were included. Compared to HCs, IBS patients were characterized by higher prevalences for adverse childhood experiences (63.8% vs. 48.0%, pâ¯=â¯.02, ORâ¯=â¯1.33) and increased levels of illness anxiety (pâ¯<â¯.001, η2â¯=â¯0.595). Taking into account gender specific effects, there was a significant correlation between adverse childhood experiences and illness anxiety in female IBS patients, but not in male (râ¯=â¯0.242, pâ¯=â¯.03 vs. râ¯=â¯0.162, pâ¯=â¯.29). However, after controlling for depression and anxiety, this correlation disappeared. CONCLUSION: Our findings suggest a possible gender-specific association of ACE with illness anxiety in female IBS patients that might be linked to increased levels of depression and anxiety.

ORCA.IT, a new online test of online research and comprehension was developed for the Italian population. A group of 183 students attending various types of upper secondary schools in Northern Italy were tested with the new tool and underwent further cognitive and neuropsychological assessment. The different school types involved in the study are representative of the school population in the Italian system, but can also be easily compared with the educational systems of other countries. The new test turned out to have good psychometric properties after accurate item construction and final selection. In particular, Version 1 showed better characteristics than Version 2. Subsequently, comparison with one-way ANOVAs were performed to test whether differences exist between different school types, between groups with and without reading difficulties, and between males and females. Such differences are sometimes reported in the literature, but many remain controversial. Further, Pearson's bivariate correlations were calculated to analyze associations between scores on the ORCA.IT and cognitive/neuropsychological variables. Finally, a stepwise regression analysis was performed on aggregated scores to identify the predictors of performance on each of the two versions. The test, especially in the most complete version (Version 1), appears to accurately and reliably capture students' web searching abilities and online reading comprehension. The tool could highlight differences in online search and comprehension ability between students with and without reading difficulties, not penalizing overall performance but allowing very specific weaknesses to be pointed out. Further, it seems to be able to capture differences due to both educational pathways (different school types) and social attitudes (differences between males and females). Most interestingly, it shows to be clearly resting on specific cognitive and neuropsychological abilities, including language, memory, and attentional skills, which explain a large portion of the total variance. Offline text reading comprehension is a crucial predictor of online reading performance, while decoding ability is not. Prior knowledge also influences the results, as expected. The new tool turns out to be rather independent of previous Internet experience and to measure more cognitively grounded processes related to information gathering, processing, and communicating.
RESUMEN
Hallucinations have been found to be associated with various types of source memory failure in both schizophrenia patients and hallucination-prone healthy individuals. We investigated the associations of clinical and non-clinical hallucinations with source memory errors in a visual memory task that involved the remembering of picture presentation context. 59 schizophrenia patients and 61 healthy individuals took part in the study. Pictures were presented either at different locations or in association with different visual stimuli. The participants were required afterwards to recognize the target pictures among distractors, and then to remember their spatial location or the visual stimulus that was associated with them. Liberal response bias in picture recognition was associated with hallucination proneness and auditory-verbal hallucinations in subsamples of participants with significant non-clinical or clinical hallucinations. After controlling for overall memory performance, failure to remember the spatial location of the pictures was associated with visual hallucinations in male patients; failure to remember the associated visual stimulus was related to auditory-verbal hallucinations in female patients and to hallucination proneness in healthy women. The findings suggest that both clinical and non-clinical hallucinations are associated with loss of contextual information relative to the acquisition of events.

There is growing evidence that college cannabis use is associated with use-related problems, yet efforts to reduce cannabis-related problems via online personalized feedback interventions (PFIs) have had limited success in significantly reducing risky cannabis use among college students. However, men and women may respond differently to such interventions and failure to examine effects of gender may obfuscate intervention effects. Thus, the current study tested intervention effects (moderated by gender) of an online, university-specific PFI for high-risk cannabis users (i.e., past-month cannabis users with at least one recent cannabis-related problem) who were randomly assigned to an online PFI (nâ¯=â¯102) or an online personalized normative feedback-only condition (PNF-only; nâ¯=â¯102). Gender moderated the relationship between condition and one-month follow-up problems, such that women in the PFI condition reported fewer cannabis-related problems at follow-up than women in the PNF-only condition. Men in the PFI condition did not significantly differ from men in the PNF-only condition on use-related problems at follow-up. Cannabis PFIs may be efficacious for reducing cannabis use-related problems among undergraduate women (but not men) and women may benefit from online interventions that include problem-focused components.
