Abstract
Adverse childhood experiences (ACEs) are recognised as precursors to numerous physical and mental health challenges. However, research on their impact on inhibitory control and working memory, particularly among healthy young adults, remains limited. The role played by the stress response as a moderator in these effects is likewise underexplored. Our study addresses this gap by examining cognitive impairments in non-clinical adults with early childhood trauma, specifically trauma before the age of 13 years, and by assessing the influence of the stress response on these effects. A total of 15 participants with early ACEs were compared with a control group (n = 18) using the Corsi Block Tapping Test (CBTT) and Stroop Word Colour Test (SCWT). Results showed that participants with early ACEs exhibited lower scores on the SCWT but not the CBTT. The stress response emerged as a potential factor in the relationship between early ACEs and cognitive performance. The implications of these findings are then discussed in relation to the existing literature.

Abstract
Although the association between cognitive performances and the onset of psychiatric disorders has been widely investigated, limited research on the role of childhood trauma or early life stress (CT/ELS), and whether this role differs between clinical and non-clinical cohorts is available. This systematic review aims at filling this gap, testing whether the occurrence of CT/ELS and its subtypes are associated with cognitive domains (general cognitive ability, executive functions, working memory, attention, processing speed, verbal/visual memory) in patients with psychiatric disorders and in non-clinical populations. This study followed the PRISMA 2020 guidelines and the Newcastle-Ottawa scale for quality assessment. The search was performed until May 2022. Seventy-four studies were classified as eligible. The graphical representations of the results reported an association between exposure to CT/ELS and worse general cognitive ability, verbal/visual memory, processing speed and attention in patients affected by anxiety, mood and psychotic disorders, and that specific CT/ELS subtypes (physical neglect, physical/sexual abuse) can differentially influence specific cognitive abilities (executive functions, attention, working memory, verbal/visual memory). In non-clinical cohorts we found associations between CT/ELS exposure and impairments in executive functions, processing speed and working memory, while physical neglect was related to general cognitive ability and working memory. Concerning the emotional abuse/neglect subtypes in both populations, the results indicated their involvement in cognitive functioning; however, the few studies conducted are not enough to reach definitive conclusions. These findings suggest an association of CT/ELS with specific cognitive deficits and psychopathology.

Abstract
Childhood maltreatment is a potent interpersonal trauma associated with dysregulation of emotional processes relevant to the development of psychopathology. The current study identified prospective links between patterns of maltreatment exposures and dimensions of emotion regulation in emerging adulthood. Participants included 427 individuals (48% Male; 75.9% Black, 10.8% White, 7.5% Hispanic, 6% Other) assessed at two waves. At Wave 1, children (10-12 years) from families eligible for public assistance with and without involvement with Child Protective Services took part in a research summer camp. Patterns of child maltreatment subtype and chronicity (based on coded CPS record data) were used to predict Wave 2 (age 18-24 years) profiles of emotion regulation based on self-report, and affective processing assessed via the Affective Go/No-Go task. Results identified associations between task-based affective processing and self-reported emotion regulation profiles. Further, chronic, multi-subtype childhood maltreatment exposure predicted difficulties with aggregated emotion dysregulation. Exposure to neglect with and without other maltreatment subtypes predicted lower sensitivity to affective words. Nuanced results distinguish multiple patterns of emotion regulation in a sample of emerging adults with high exposure to trauma and socioeconomic stress and suggest that maltreatment disrupts emotional development, resulting in difficulties identifying emotions and coping with emotional distress.

Abstract
The experience of childhood trauma is known to predict health-relevant outcomes across the lifespan. Previous reviews summarize existing knowledge of the implications of childhood trauma for health in young adults and adults more generally. The current theoretical review aims to integrate the existing literature on the relationship between childhood trauma and health-relevant outcomes specifically in college students, consolidating findings across specific health domains. Further, the following theoretical review highlights the need for more research in this area and discusses how college campuses may use the knowledge in this area of work to develop targeted interventions aimed at improving the health of college students who experienced trauma in childhood.

Working memory and emotional interpretation bias in a sample of Syrian refugee adolescents. Eur Child Adolesc Psychiatry 2021; 30:1885-1894.

Abstract
The number of adolescent refugees around the world has been continuously increasing over the past few years trying to escape war and terror, among other things. Such experience not only increases the risk for mental health problems including anxiety, depression, and post-traumatic stress disorder (PTSD), but also may have implications for socio-cognitive development. This study tested cognitive-affective processing in refugee adolescents who had escaped armed conflict in Syria and now resided in Istanbul, Turkey. Adolescents were split into a high trauma (n = 31, 12 girls, mean age = 11.70 years, SD = 1.15 years) and low trauma (n = 27, 14 girls, mean age = 11.07 years, SD = 1.39 years) symptom group using median split, and performed a working memory task with emotional distraction to assess cognitive control and a surprise faces task to assess emotional interpretation bias. The results indicated that high (vs. low) trauma symptom youth were ~ 20% worse correctly remembering the spatial location of a cue, although both groups performed at very low levels. However, this finding was not modulated by emotion. In addition, although all youths also had a ~ 20% bias toward interpreting ambiguous (surprise) faces as more negative, the high (vs. low) symptom youth were faster when allocating such a face to the positive (vs. negative) emotion category. The findings suggest the impact of war-related trauma on cognitive-affective processes essential to healthy development.

Abstract
This study aimed to (i) explore the association between perceptions of negative social relationships in childhood with significant others, including peers, guardians and teachers, symptoms of depression and OCD, and suicide behaviors, and (ii) examine whether depression and OCD severity meditated the association between these perceptions and suicide experiences. In total, 783 individuals from the community were invited to complete self-report measures. There were strong associations between perceptions of adverse social relationships in childhood, severity of depression and OCD, and suicide behaviors. Furthermore, depression and OCD partially mediated the association between perceptions of adverse social relationships, especially with peers, and suicide behaviors. These results provide strong evidence for the importance of developing clinical interventions that directly target negative experiences of social relationships in childhood, and for raising public and scientific awareness that everyday adverse social interactions with significant others can impact negatively on mental health including suicide behaviors.

Abstract
BACKGROUND Maternal prenatal stress is associated with worse socio-emotional outcomes in offspring throughout childhood. However, the association between prenatal stress and later caregiving sensitivity is not well understood, despite the significant role that caregiving quality plays in child socio-emotional development. The goal of this study was to examine whether dimensions of pregnancy-specific stress are correlated with observer-based postnatal maternal caregiving sensitivity in pregnant adolescents. METHODS Healthy, nulliparous pregnant adolescents (n = 244; 90 % LatinX) reported on their pregnancy-specific stress using the Revised Prenatal Distress Questionnaire (NuPDQ). Of these 244, 71 participated in a follow-up visit at 14 months postpartum. Videotaped observations of mother-child free play interactions at 14 months postpartum were coded for maternal warmth and contingent responsiveness. Confirmatory factor analysis of the NuPDQ supported a three-factor model of pregnancy-specific stress, with factors including stress about the social and economic context, baby's health, and physical symptoms of pregnancy. RESULTS Greater pregnancy-specific stress about social and economic context and physical symptoms of pregnancy was associated with reduced maternal warmth but not contingent responsiveness. CONCLUSIONS Heightened maternal stress about the social and economic context of the perinatal period and physical symptoms of pregnancy may already signal future difficulties in caregiving and provide an optimal opening for early parenting interventions.

Abstract
BACKGROUND AND OBJECTIVES Childhood abuse and neglect increase the risk for psychiatric disorders (e.g., depression and anxiety) during adulthood and have been associated with deficits in cognitive control. The specific mechanisms underlying these cognitive control deficits are still unknown. METHODS This study examined the expectation for reward to improve inhibitory control in young women (ages 18-35 years) with a history of childhood sexual and/or physical abuse (AG, N = 28), childhood emotional and/or physical neglect (NG, N = 30), or unaffected comparison women (HC, N = 40). They completed a previously validated rewarded (color-word) Stroop task and filled out questionnaires on depression, anxiety, and resilience. RESULTS Surprisingly, a significant group by reward interaction revealed larger performance benefits under reward prospect (relative to no-reward) for the AG group relative to both the NG and HC groups. LIMITATIONS A small sample size limiting generalizability. CONCLUSIONS These results demonstrate sensitivity of abused subjects to reward in modulating cognitive control and might aid in discussing whether using reward schedules during therapeutic interventions could be effective.

Abstract
Adverse experiences in early life have a long-term impact on the development of brain, which in turn increases the susceptibility to mental illness during adulthood, especially in female subjects. However, whether and how the visual cortex is affected by these adverse experiences as well as the mechanisms underlying the sex difference are largely unknown. Here, we established a new mouse model of early-life chronic mild stress (ECMS) without anxiety or depression-like behavior in adulthood. ECMS mice showed normal maturation of visual acuity and orientation/direction selectivity, whereas their visual cortical neurons preferred lower spatial frequency (SF) and higher temporal frequency (TF) than control mice. Meanwhile the development of ocular dominance (OD) plasticity was delayed. Specifically, compared with control mice, ECMS mice in the early stage of the critical period (CP) showed a reduction in GABA synthesis enzyme expression as well as lower OD plasticity which could be occluded by diazepam. In contrast, ECMS mice in the late stage of CP showed stronger OD plasticity, accompanied by higher expression of N-methyl-D-aspartate (NMDA) receptor NR2B subunit. Interestingly, only female ECMS mice at adulthood maintained juvenile-like OD plasticity as well as high NR2B expressions. Artificial increase in estradiol level in ECMS males via estradiol supplementary diminished this sex difference. Lastly, OD plasticity was abolished in adult ECMS females either performed with the bilateral ovariectomy in prepuberty, or directly infused with NR2B antagonist Ro 25–6981 into the visual cortex. Overall, our study demonstrates that early adverse experiences have a lasting effect on visual development of mice in a sex-dependent manner, which is mediated by the estradiol-NR2B pathway.

Childhood trauma and adult declarative memory performance in the general population: The mediating effect of alexithymia. CHILD ABUSE & NEGLECT 2020; 101:104311. [PMID: 31877447 DOI: 10.1016/j.chiabu.2019.104311] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2019] [Revised: 10/21/2019] [Accepted: 12/02/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Previous studies suggested that childhood maltreatment is associated with altered memory performance in adulthood. Deficits in identifying and describing feelings as captured by the alexithymia construct are strongly linked with childhood trauma and may mediate the associations with memory function. OBJECTIVE To investigate the associations of childhood trauma with verbal declarative memory performance and the putative mediating role of alexithymia. METHOD Associations of the different dimensions of childhood trauma with adult declarative memory performance were tested in two large, independent general population samples comprising a total of N = 5574 participants. Moreover, we tested whether associations were mediated by alexithymia. RESULTS In both samples, childhood emotional neglect, but not abuse emerged as a negative statistical predictor of early (sample 1: β=-1.79; p < 0.001, sample 2: β=-0.26; p < 0.001) as well as delayed recall (β=-0.78; p < 0.001; β=-0.24; p < 0.05). Likewise, childhood emotional neglect was the strongest predictor for alexithymia (β = 3.2; p < 0.001; β = 3.54; p < 0.001). Finally, the association between childhood emotional neglect and early (Total Mediated Effect (TME): 13.2, CI: 0.087-0.302; TME: 20.1; CI: 0.123-0.619) as well as late recall (TME: 13.2, CI: 0.086-0.301; TME: 9; CI: -0.442-0.699) was significantly mediated by alexithymia. CONCLUSIONS Our findings suggest that childhood emotional neglect is particularly detrimental to memory functioning in adulthood. In comparison, childhood abuse was not associated with reduced declarative memory capacity. Our results contribute to explain the mechanism underlying the relation of childhood trauma and memory deficits: Finding specific associations with emotional neglect and a mediating role of alexithymia highlights the relevance of emotion processing capacities for memory functioning.

Abstract
It has been suggested that altered processing of emotion during cognitive control plays an important role in the etiology of depressive symptoms. The current study investigates the influence of emotional stimuli on working memory (WM) in adolescents with dysphoric symptomatology (DS). Twenty-five adolescents with DS and 40 adolescents with no dysphoric symptomatology (NDS) completed a memory-guided eye movement task. This task assessed the influence of irrelevant affective information on WM processes during high and low cognitive load. Latency analyses showed that, in the high load WM condition, negative distractors disturbed WM performance in adolescents with NDS, but not in adolescents with DS. Accuracy analyses revealed that adolescents with NDS had higher accuracy rates in the presence of positive distractors relative to negative and neutral distractors, and in comparison to adolescents with DS. The findings indicated altered WM performance in the context of emotional distractors in adolescents with DS and may contribute to theoretical knowledge and early prevention of youth depression.

Abstract
A contemporary model for the pathogenesis of mood disorders (bipolar and depressive disorders) involves gene-environmental interaction, with genetic predisposition, epigenetic regulation, and environmental effects. Among multiple environmental factors, the experience of childhood trauma can be connected with the pathogenesis, course and the treatment of mood disorders. Patients with mood disorders have the greater frequency of childhood trauma compared with the general population, and adverse childhood experiences can exert a negative impact on their clinical course. In this article, the neurobiological mechanisms of childhood trauma are presented. The influence of negative childhood experiences on the central nervous system can result in many structural and functional changes of the brain, including such structures as hippocampus and amygdala, associated with the development of bipolar and depressive illnesses. Interaction of several genes with childhood trauma to produce pathological, clinical phenomena in adulthood has been demonstrated, the most important in this respect being the serotonin transporter gene and the FKBP5 gene playing an important role in the pathogenesis of mood disorders. Neurobiological effects can also involve epigenetic mechanisms such as DNA methylation which can exert an effect on brain function over long-term periods. Somatic effects of childhood trauma include disturbances of stress axis and immune-inflammatory mechanisms as well as metabolic dysregulation. Negative childhood experiences may also bear implications for the treatment of mood disorders. In the article, the impact of such experiences on the treatment of mood disorders will be discussed, especially in the context of treatment -resistance to antidepressants and mood-stabilizing drugs.

Abstract
Children experiencing or witnessing violence in the home are at risk of a number of cognitive, social, and behavioral challenges as they age. A handful of recent studies have suggested that food insecurity may be one factor associated with violence against children in the home. The present study uses data from the Early Childhood Longitudinal Study-Birth Cohort to explore the link between household food insecurity during the first three waves of data collection (i.e., the first few years of life) and witnessing or being the victim of violence in the home among very young children (~ age 4). The results suggest that the predicted probability of early childhood exposure to violence and/or victimization in the home is nearly 6 times greater in persistently food-insecure households (i.e., households that are food insecure across all three waves) relative to food secure households. Limitations and avenues for future research are noted.

Abstract
Violence exposure during childhood is common and associated with poor cognitive and academic functioning. However, little is known about how violence exposure influences cognitive processes that might contribute to these disparities, such as working memory, or their neural underpinnings, particularly for cognitive processes that occur in emotionally salient contexts. We address this gap in a sample of 54 participants aged 8 to 19 years (50% female), half with exposure to interpersonal violence. Participants completed a delayed match to sample task for emotional faces while undergoing functional magnetic resonance imaging scanning. Violence-exposed youth performed worse than controls on happy and neutral, but not angry, trials. In whole-brain analysis, violence-exposed youth had reduced activation in the left middle frontal gyrus and right intraparietal sulcus during encoding and the left superior temporal sulcus and temporal-parietal junction during retrieval compared to control youth. Reduced activation in the left middle frontal gyrus during encoding and the left superior temporal sulcus during retrieval mediated the association between violence exposure and task performance. Violence exposure influences the frontoparietal network that supports working memory as well as regions involved in facial processing during working memory for emotional stimuli. Reduced neural recruitment in these regions may explain atypical patterns of cognitive processing seen among violence-exposed youth, particularly within emotional contexts.

Abstract
Introduction: Gender dysphoria (GD) (DMS-5) is a condition marked by increasing psychological suffering that accompanies the incongruence between one's experienced or expressed gender and one's assigned gender. Manifestation of GD can be seen early on during childhood and adolescence. During this period, the development of undesirable sexual characteristics marks an acute suffering of being opposite to the sex of birth. Pubertal suppression with gonadotropin releasing hormone analogs (GnRHa) has been proposed for these individuals as a reversible treatment for postponing the pubertal development and attenuating psychological suffering. Recently, increased interest has been observed on the impact of this treatment on brain maturation, cognition and psychological performance. Objectives: The aim of this clinical report is to review the effects of puberty suppression on the brain white matter (WM) during adolescence. WM Fractional anisotropy, voice and cognitive functions were assessed before and during the treatment. MRI scans were acquired before, and after 22 and 28 months of hormonal suppression. Methods: We performed a longitudinal evaluation of a pubertal transgender girl undergoing hormonal treatment with GnRH analog. Three longitudinal magnetic resonance imaging (MRI) scans were performed for diffusion tensor imaging (DTI), regarding Fractional Anisotropy (FA) for regions of interest analysis. In parallel, voice samples for acoustic analysis as well as executive functioning with the Wechsler Intelligence Scale (WISC-IV) were performed. Results: During the follow-up, white matter fractional anisotropy did not increase, compared to normal male puberty effects on the brain. After 22 months of pubertal suppression, operational memory dropped 9 points and remained stable after 28 months of follow-up. The fundamental frequency of voice varied during the first year; however, it remained in the female range. Conclusion: Brain white matter fractional anisotropy remained unchanged in the GD girl during pubertal suppression with GnRHa for 28 months, which may be related to the reduced serum testosterone levels and/or to the patient's baseline low average cognitive performance.Global performance on the Weschler scale was slightly lower during pubertal suppression compared to baseline, predominantly due to a reduction in operational memory. Either a baseline of low average cognition or the hormonal status could play a role in cognitive performance during pubertal suppression. The voice pattern during the follow-up seemed to reflect testosterone levels under suppression by GnRHa treatment.

Abstract
Repeated exposure to stress during childhood is associated with increased risk for neuropsychiatric illness, substance use disorders and other behavioral problems in adulthood. However, it is not clear how chronic childhood stress can lead to emergence of such a wide range of symptoms and disorders in later life. One possible explanation lies in stress-induced disruption to the development of specific brain regions associated with executive function and reward processing, deficits in which are common to the disorders promoted by childhood stress. Evidence of aberrations in prefrontal cortex and nucleus accumbens function following repeated exposure of juvenile (pre- and adolescent) organisms to a variety of different stressors would account not only for the similarity in symptoms across the wide range of childhood stress-associated mental illnesses, but also their persistence into adulthood in the absence of further stress. Therefore, the goal of this review is to evaluate the current knowledge regarding disruption to executive function and reward processing in adult animals or humans exposed to chronic stress over the juvenile period, and the underlying neurobiology, with particular emphasis on the prefrontal cortex and nucleus accumbens. First, the role of these brain regions in mediating executive function and reward processing is highlighted. Second, the neurobehavioral development of these systems is discussed to illustrate how juvenile stress may exert long-lasting effects on prefrontal cortex-accumbal activity and related behavioral functions. Finally, a critical review of current animal and human findings is presented, which strongly supports the supposition that exposure to chronic stress (particularly social aggression and isolation in animal studies) in the juvenile period produces impairments in executive function in adulthood, especially in working memory and inhibitory control. Chronic juvenile stress also results in aberrations to reward processing and seeking, with increased sensitivity to drugs of abuse particularly noted in animal models, which is in line with greater incidence of substance use disorders seen in clinical studies. These consequences are potentially mediated by monoamine and glutamatergic dysfunction in the prefrontal cortex and nucleus accumbens, providing translatable therapeutic targets. However, the predominant use of male subjects and social-based stressors in preclinical studies points to a clear need for determining how both sex differences and stressor heterogeneity may differentially contribute to stress-induced changes to substrates mediating executive function and reward processing, before the impact of chronic juvenile stress in promoting adult psychopathology can be fully understood.

Abstract
College students who report a history of childhood maltreatment may be at risk for poor outcomes. In the current study, we conducted an exploratory analysis to examine potential models that statistically mediate associations between aspects of maltreatment and aspects of academic outcome, with a particular focus on executive functions (EF). Consistent with contemporary EF research, we distinguished between relatively "cool" EF tasks (i.e., performed in a context relatively free of emotional or motivational valence) and "hot" EF tasks that emphasize performance under more emotionally arousing conditions. Sixty-one male and female college undergraduates self-reported childhood maltreatment history (emotional abuse and neglect, physical abuse and neglect, and sexual abuse) on the Childhood Trauma Questionnaire (CTQ), and were given two EF measures: (1) Go-No-Go (GNG) test that included a Color Condition (cool); Neutral Face Condition (warm); and Emotion Face condition (hot), and (2) Iowa Gambling Task (IGT), a measure of risky decision making that reflects hot EF. Academic outcomes were: (1) grade point average (GPA: first-semester, cumulative, and semester concurrent with testing), and (2) Student Adaptation to College Questionnaire (SACQ). Correlational patterns suggested two EF scores as potential mediators: GNG reaction time (RT) in the Neutral Face condition, and IGT Block 2 adaptive responding. Indirect effects analyses indicated that IGT Block 2 adaptive responding has an indirect effect on the relationship between CTQ Total score and 1st semester GPA, and between CTQ Emotional Abuse and concurrent GPA. Regarding college adaptation, we identified a consistent indirect effect of GNG Neutral Face RT on the relationship between CTQ Emotional Neglect and SACQ total, academic, social, and personal-emotional adaption scores. Our results demonstrate that higher scores on a child maltreatment history self-report negatively predict college academic outcomes as assessed by GPA and by self-reported adaptation. Further, relatively "hot" EF task performance on the IGT and GNG tasks serves as a link between child maltreatment experiences and college achievement and adaptation, suggesting that hot EF skills may be a fruitful direction for future intervention efforts to improve academic outcomes for this population.

Abstract
BACKGROUND There is a paucity of research on correlates of child maltreatment in limited-resource countries with a relatively high tolerance of harsh discipline. This Vietnamese study aimed to investigate associations between different types of child maltreatment and child emotional, cognitive, and physical health functioning as well as moderation effects of gender and ethnicity. METHODS This cross-sectional study was conducted with 1851 randomly selected students aged 12-17 years. Both self-report and more objective measures (weight, height, study ranking, and a memory test) were used. RESULTS All types of child maltreatment were associated with emotional dysfunctioning. Life time and past year experiences of physical abuse and life time experiences of sexual abuse and neglect were related to poorer perceived physical health. The study did not find associations between any type of child maltreatment and overweight or underweight status. Regarding cognitive functioning, life time experience of sexual abuse and neglect were related to poorer working memory performance. Noticeably, emotional abuse was related to better academic performance, which might be an indication of "tiger parenting" practice in Vietnam, implying academic performance stimulation at the expense of emotional security. No significant moderation effects by gender and ethnicity were found. CONCLUSION Even in a culture in which harsh discipline is normative, child maltreatment was related to negative aspects of child wellbeing including emotional, cognitive, and physical health functioning. Efficient and low-cost interventions on child maltreatment should be developed and conducted in Vietnam as well as other countries with similar contexts.

Abstract
Literature that has examined maternal self-reported history of abuse and an observational assessment of infant-mother interaction were reviewed. Electronic databases were searched, and studies that met predefined criteria were included. Fourteen (12 independent samples) studies were included and assessed for quality using the Effective Public Health Practice Project tool (National Collaborating Centre for Methods and Tools, 2008). Ten of the 14 studies found a direct or an indirect relationship between self-reported abuse and observed caregiving. The small number of studies and variation in sample characteristics and measurement limit conclusions. Of the studies that were rated of the highest quality, there is some consistency showing that the effect of maternal abuse history on caregiving may be via a third variable (i.e., stress reactivity or depressive symptoms). The current review discusses strengths and limitations of the existing literature and offers suggestions for future research.

Abstract
Previous research suggests that a history of early life stress (ELS) impacts working memory (WM) in adulthood. Despite the widespread use of WM paradigms, few studies have evaluated whether ELS exposure, in the absence of psychiatric illness, also impacts WM-associated brain activity in ways that might improve sensitivity to these ELS effects or provide insights into the mechanisms of these effects. This study evaluated whether ELS affects WM behavioral performance and task-associated activity by acquiring 3T functional images from 27 medication-free healthy adults (14 with ELS) during an N-back WM task that included 0- and 2-back components. Whole brain voxel-wise analysis was performed to evaluate WM activation, followed by region of interest analyses to evaluate relationships between activation and clinical variables. ELS was associated with poorer accuracy during the 2-back (79% ± 19 vs. 92% ± 9, p = 0.049); accuracy and response time otherwise did not differ between groups. During the 0-back, ELS participants demonstrated increased activation in the superior temporal gyrus/insula, left inferior parietal lobule (IPL) (both corrected p < 0.001), and middle temporal and parahippocampal gyrus (MTG/PHG)(corrected p < 0.010). During the 2-back, ELS was associated with greater activation in the IPL, MTG/PHG and inferior frontal gyrus (corrected p < 0.001), with a trend towards precuneus activation (p = 0.080). These findings support previous research showing that ELS is associated with impaired neurobehavioral performance and changes in brain activation, suggesting recruitment of additional cognitive resources during WM in ELS. Based on these findings, ELS screening in future WM imaging studies appears warranted.

Abstract
How does the affective nature of task stimuli modulate working memory (WM)? This study investigates whether WM maintains emotional information in a biased manner to meet the motivational principle of approaching positivity and avoiding negativity by retaining more approach-related positive content over avoidance-related negative content. This bias may exist regardless of individual differences in WM functionality, as indexed by WM capacity (overall bias hypothesis). Alternatively, this bias may be contingent on WM capacity (capacity-based hypothesis), in which a better WM system may be more likely to reveal an adaptive bias. In two experiments, participants performed change localisation tasks with emotional and non-emotional stimuli to estimate the number of items that they could retain for each of those stimuli. Although participants did not seem to remember one type of emotional content (e.g. happy faces) better than the other type of emotional content (e.g. sad faces), there was a significant correlation between WM capacity and affective bias. Specifically, participants with higher WM capacity for non-emotional stimuli (colours or line-drawing symbols) tended to maintain more happy faces over sad faces. These findings demonstrated the presence of a "built-in" affective bias in WM as a function of its systematic limitations, favouring the capacity-based hypothesis.

Abstract
The relationship between developmental exposure to adversity and affective disorders is reviewed. Adversity discussed herein includes physical and sexual abuse, neglect, or loss of a caregiver in humans. While these stressors can occur at any point during development, the unique temporal relationship to specific depressive symptoms was the focus of discussion. Further influences of stress exposure during sensitive periods can vary by gender and duration of abuse as well. Data from animal studies are presented to provide greater translational and causal understanding of how sensitive periods, different types of psychosocial stressors, and sex interact to produce depressive-like behaviors. Findings from maternal separation, isolation rearing, chronic variable stress, and peer-peer rearing paradigms clarify interpretation about how various depressive behaviors are influenced by age of exposure. Depressive behaviors are broken down into the following categories: mood and affect, anhedonia, energy, working memory, sleep-wake, appetite changes, suicide, and general malaise. Cross-species evidence from humans, nonhuman primates, rats, and mice within each of these categories is discussed. In conclusion, sensitive periods for affective-related behaviors (anxiety, mood, and controllability) occur earlier in life, while other aspects of depression are associated with adversity later during adolescence.

Abstract
Childhood maltreatment has been shown to increase the risk of a range of psychiatric disorders including substance use disorders (SUDs) and is associated with the onset, course and severity of illness. We review the evidence for alterations in brain structure and neurocognitive processing in individuals who have experienced childhood maltreatment, focusing specifically on changes related to reward processing, executive functioning and affect processing. Changes in these neurocognitive systems have been documented in adults presenting with SUDs, who are typically characterized by heightened subcortico-striatal responses to salient stimuli and impairments in fronto-cingulate regulation. Maltreatment-specific effects in these processing domains may account for the particularly severe clinical presentation of SUDs in adults with histories of maltreatment in childhood. The findings are considered in relation to the theory of latent vulnerability, which contends that alterations in these neurocognitive systems may reflect calibration to early risk environments that in turn increases the risk of developing of SUDs later in life.

Abstract
Theories of adolescent behaviour attribute increases in risk-taking and sensation-seeking in this age group to a heightened sensitivity to emotional stimuli on the one hand and a relatively immature cognitive control system on the other hand. However, little research has outlined to what extent relevant and irrelevant emotional stimuli bias the imbalance between affective processing and cognitive control. Thirty-three adolescents (19 females, aged 12-14) and 37 adults (18 females, aged 18-29) completed two attentional conditions of an emotional face working memory (WM) 0-back/2-back task. Participants were asked to attend to the emotional facial expression in the "relevant" emotion condition, and to the gender of the face in the "irrelevant" condition. The results revealed a WM improvement for happy faces in the relevant condition in both age groups, and an impairment for irrelevant happy faces in adolescents, but not adults. Furthermore, the difference between both attentional conditions for happy faces was larger in adolescents than adults. Results are discussed within the framework of theories of adolescent behaviour.
