Attention-Deficit/Hyperactivity Disorder and Subsequent Trauma Exposure: The Mediating Role of Deviant Peer Affiliation.

Individuals with ADHD symptoms are at an increased risk of lifetime trauma exposure. However, research has yet to fully examine whether symptoms of ADHD function as a temporal risk factor for experiencing trauma and specific mechanisms that may explain the association between symptoms of ADHD and trauma exposure. Two constructs that may account for the relation between ADHD symptoms and trauma are deviant peer association and neighborhood disadvantage. The present study sought to 1) elucidate the temporal nature of ADHD symptoms and exposure to trauma and 2) examine whether peer deviancy and/or neighborhood disadvantage mediate the relation between childhood ADHD symptoms and subsequent trauma exposure across a 20-year longitudinal cohort study. Participants (N = 616) were predominantly Black/African American (86%; Male n = 389) from an urban school district. Using structural equation modeling, total trauma exposures during young adulthood (Years 17-20) were regressed on parent- and teacher-rated ADHD symptoms in Grade 1 (Year 1). A significant indirect path from ADHD symptoms to trauma exposure through deviant peer affiliation (Year 16) indicated that having childhood ADHD symptoms predicted deviant peer affiliation 16 years later, which in turn predicted greater exposures to traumatic events during young adulthood, controlling for neighborhood disadvantage. Neighborhood disadvantage was not a significant mediator when accounting for peer deviancy. Taken together, findings contribute to a limited body of research that utilizes a prospective design to examine the association between childhood ADHD symptoms and trauma exposure in young adulthood among Black/African American youth. Potential targets for intervention are proposed.

'Eccentricity', by DH Tuke (1892).

An astronomical concept up to the eighteenth century, 'eccentricity' started to be used to refer to behaviours considered as odd, strange, rare, extravagant, etc. Once reified into a personality trait, it gained explanatory power. This not only increased its popularity but also facilitated its links with psychopathology and neuropsychology, and, via the shared concept of madness, with the notions of genius and creativity. This Classic Text describes the process whereby Alienism (Psychiatry) medicalized eccentricity. To this day, the latter remains firmly attached to 'psychoticism' and to some personality disorders.

Automatic detection of irregular vanishing and reappearing parts of objects in two interwoven sequences: A visual mismatch negativity study.

The cognitive system automatically develops predictions on the basis of regularities of event sequences and reacts to the violation of these predictions. In the visual modality, the electrophysiological signature of this process is an event-related potential component, the visual mismatch negativity (vMMN). So far, we have no data, whether the system underlying vMMN is capable of dealing with more than one event sequence simultaneously. To disclose this aspect of the capacity of the system, in a passive oddball paradigm, we presented two interwoven sequences. The stimuli were objects (diamond patterns with their diagonals), one of the sequences was presented to the left side and the other to the right side of the visual field. From time to time, two parallel lines of the diamonds disappeared (OFF event) and then reappeared (ON event). The frequently vanishing pair of lines on the left side (standard) was identical to the rarely vanishing lines of the objects on the right side (deviant) and vice versa. We found that deviant ON events elicited vMMN only for left-side deviants and deviant OFF events elicited vMMN only for right-side deviants. The standardized low resolution brain electromagnetic tomography (sLORETA) source localization showed vMMN sources both in posterior visual structures and in anterior locations, and activity was stronger in the hemisphere contralateral to the deviant event. According to the results, the system underlying vMMN is capable of dealing with two sequences, but within a sequence, it detected only one type (either OFF or ON) of deviancy.

Deviancy Aversion and Social Norms.

We propose that deviancy aversion-people's domain-general discomfort toward the distortion of patterns (repeated forms or models)-contributes to the strength and prevalence of social norms in society. Five studies (N = 2,390) supported this hypothesis. In Study 1, individuals' deviancy aversion, for instance, their aversion toward broken patterns of simple geometric shapes, predicted negative affect toward norm violations (affect), greater self-reported norm following (behavior), and judging norms as more valuable (belief). Supporting generalizability, deviancy aversion additionally predicted greater conformity on accuracy-orientated estimation tasks (Study 2), adherence to physical distancing norms during COVID-19 (Study 3), and increased following of fairness norms (Study 4). Finally, experimentally heightening deviancy aversion increased participants' negative affect toward norm violations and self-reported norm behavior, but did not convincingly heighten belief-based norm judgments (Study 5). We conclude that a human sensitivity to pattern distortion functions as a low-level affective process that promotes and maintains social norms in society.

Alcohol and Cannabis Use Milestones in Diverse Urban Adolescents: Associations with Demographics, Parental Rule Setting, Sibling and Peer Deviancy, and Outcome Expectancies.

Objective: Alcohol and cannabis use progression milestones in adolescence (such as ages at first use, first intoxication and at onset of regular use) may inform the development of alcohol and cannabis use disorders. Although parent, sibling, and peer behavior and alcohol-related cognitions have been shown to be associated with alcohol milestone attainment, findings have been mixed; further, those factors' associations with cannabis use milestones are unknown. This study examined whether progression through such milestones differed as a function of perceived peer/sibling deviancy, parental rule-setting, and substance use outcome expectancies in a racially diverse adolescent sample.Methods: Data were drawn from a two-wave longitudinal health survey study of 9-11th graders (n = 355 for the current analyses; Mage=15.94 [SD = 1.07]; 44% male; 43% Black; 22% White; 18% Asian; 17% Multiracial; 10% Hispanic/Latinx ethnicity) at an urban high school. A series of logistic and proportional hazards regressions examined associations of peer/sibling deviancy, parental rule-setting, and outcome expectancies with age and attainment of alcohol/cannabis use milestones.Results: For both alcohol and cannabis, greater peer deviancy and positive expectancies were associated with higher odds of milestone attainment, while negative expectancies were associated with slower progression through milestones. For cannabis, but not alcohol, greater perceived sibling deviancy was positively associated with milestone attainment, while negative expectancies were associated with lower odds of milestone attainment.Conclusions: Perceived deviant behavior by peers and siblings, in addition to adolescents' expectancies for either alcohol or cannabis use, is associated with attainment and progression through key adolescent substance use milestones.

Developmental Cascade Effects of Maternal Depression on Offspring Substance Use Across Adolescence: Pathway Through Mother-Child Relationship Quality and Peer Deviancy.

There is evidence that maternal depression can disrupt adolescent social development and trigger a risk cascade to adolescent substance use that involves poor quality mother-child relationships (Lovejoy et al., 2000) and affiliation with deviant peers (Visser et al., 2012). However, relatively little work has considered maternal depression as a catalyst for this risk pathway to adolescent substance use. The current study aims to clarify whether maternal depression has cascading effects to adolescent substance use through related developmental systems. Using structural equation modeling and bootstrapping for testing indirect effects, we tested the prospective association between maternal depression and middle adolescent substance use and whether poor mother-child relationship quality and peer deviancy mediated this relationship. We controlled for a variety of important cofounding variables. The sample included N = 338 adolescents (57% female; predominantly non-Hispanic Caucasian (83.14%) or African American (8.88%)) and mothers drawn from a larger nine-year longitudinal study of adolescent substance use. Data from wave 1 through wave 6 of the longitudinal project were utilized. The average age of adolescents was 11.6, 12.6, 13.6, 14.6, 15.5, and 16.6 at W1-W6, respectively. The indirect effect from maternal depression to substance use was supported (ab = 0.03, 95% CI [0.002, 0.07]). Findings emphasize that future work should more closely examine how maternal depression operates in developmental cascade models of adolescent substance use.

Adolescents' externalizing behaviors and antisocial text messaging across the broader peer network: Implications for socialization and selection effects.

Adolescents' peer networks provide an important context that can contribute to increases in antisocial behavior. By a process called deviancy training, peers can both model and reinforce these behaviors, thereby conveying group norms about the acceptability of such behaviors. This research examined the relationship between the proportion of adolescents' peers who exchanged antisocial text messages and externalizing behaviors during high school. In Study 1, parent-, teacher-, and self-reports of rule-breaking and aggression were collected for a sample of adolescents (n = 167, 80 girls; 22.2% Black, 51.5% Caucasian, 18.7% Hispanic) during the summers before and after 9th grade. Total text frequency, frequency of antisocial texts, and the proportion of the peer network who exchanged antisocial messages were examined as predictors of antisocial behavior. The proportion of peers who exchanged antisocial texts significantly predicted rule-breaking, but not aggression. Study 2 examined the direction of the relationship documented in Study 1 more thoroughly. Externalizing behaviors at 9th, 10th, and 11th grade were evaluated as predictors of the proportion of the peer network that exchanged texts about antisocial topics (n = 205, 98 girls; 22.4% Black, 53.7% Caucasian, 16.9% Hispanic). Externalizing behaviors predicted the proportion of adolescents' peer network that exchanged antisocial texts in each of the subsequent years, but this proportion of the peer network exchanging antisocial communication did not predict subsequent externalizing behaviors. The findings suggest that the extent to which antisocial communication permeates the peer group is a selection effect.

A division of labor between power and phase coherence in encoding attention to stimulus streams.

Both time-based (when) and feature-based (what) aspects of attention facilitate behavior, so it is natural to hypothesize additive effects. We tested this conjecture by recording response behavior and electroencephalographic (EEG) data to auditory pitch changes, embedded at different time lags in a continuous sound stream. Participants reacted more rapidly to larger rather than smaller feature change magnitudes (deviancy), as well as to changes appearing after longer rather than shorter waiting times (hazard rate of response times). However, the feature and time dimensions of attention separately contributed to response speed, with no significant interaction. Notably, phase coherence at low frequencies (delta and theta bands, 1-7 Hz) predominantly reflected attention capture by feature changes, while oscillatory power at higher frequency bands, alpha (8-12 Hz) and beta (13-25 Hz) reflected the orienting of attention in time. Power and phase coherence predicted different portions of response speed variance, suggesting a division of labor in encoding sensory attention in complex auditory scenes.

An experimental investigation of the influence of deviant peers on own deviancy: A replication study.

OBJECTIVES: This study is a replication of a study examining the causal impact of a brief exposure to deviant peers on own deviant behavior, i.e., Paternoster et al. (Journal of Research in Crime and Delinquency, 50:476-503, 2013). This study retested this design using different monetary incentives and a female deviant peer. METHODS: A total of 69 university students (61% female) from the Netherlands participated in this laboratory-based study (Mage = 20.64; SD = 2.00) under the façade of a study on individual differences predicting memory recall. Participants could earn up to 10 euros. All participants had the opportunity to cheat to illegitimately earn more money (deviancy). Participants in the experimental condition were exposed to a deviant peer who verbalized her intention to cheat, justified this behavior, and then visibly cheated on the memory recall task. RESULTS: Although participants in both conditions engaged in some deviancy, the brief exposure to a deviant peer significantly increased the amount of deviancy compared to participants who were not exposed to a deviant peer. These results were consistent after controlling for different demographic and theoretical control variables that predict deviancy. CONCLUSIONS: Although not identical in magnitude, our results echo those found by Paternoster et al. (2013): Even a brief exposure to a previously unknown deviant peer increases the amount of deviant behavior in young adults. Future research should examine factors predicting the susceptibility to (different types and thresholds of) deviant peer influence.

The Developmental Unfolding of Sibling Influences on Alcohol Use over Time.

Research has long demonstrated that siblings are similar in their alcohol use, however much of this work relies on cross-sectional samples or samples of adolescents alone and/or exclusive focus on older siblings' impact on younger siblings. Using a three time-point design from early adolescence to early adulthood (M ages = 14.9, 18.3, and 22.4 years, respectively; 55% female; 54% European ancestry, 38% Asian ancestry), we evaluated the prospective older and younger sibling influences on alcohol use across time (N = 613 sibling pairs; 35% sisters, 26% brothers, 39% mixed-gender; average age difference = 2.34 years; 34% full-biological siblings, 46% genetically-unrelated adopted siblings, 20% pairs where one child was the biological offspring of parents and the other was adopted). The results from both the traditional and random-intercept cross-lagged panel analyses showed that older siblings' alcohol use predicted younger siblings' alcohol use across each developmental transition and across a variety of sibling contexts (e.g., gender composition, age difference, genetic relatedness). On the other hand, younger siblings' alcohol use only predicted older siblings' alcohol use when siblings were close in age (1.5 years or less) and under conditions of high sibling companionship. These results add to a body of literature illustrating how both older and younger siblings are important socializing agents of adolescent and early adult alcohol use. Assessing or co-treating siblings for alcohol problems may be an important add-on to existing adolescent and early adult alcohol prevention and intervention programs.

Best friends' interactions and substance use: The role of friend pressure and unsupervised co-deviancy.

Best friends exert a substantial influence on rising alcohol and marijuana use during adolescence. Two mechanisms occurring within friendship - friend pressure and unsupervised co-deviancy - may partially capture the way friends influence one another. The current study aims to: (1) examine the psychometric properties of a new instrument designed to assess pressure from a youth's best friend and unsupervised co-deviancy; (2) investigate the relative contribution of these processes to alcohol and marijuana use; and (3) determine whether gender moderates these associations. Data were collected through self-report questionnaires completed by 294 Canadian youths (62% female) across two time points (ages 15-16). Principal component analysis yielded a two-factor solution corresponding to friend pressure and unsupervised co-deviancy. Logistic regressions subsequently showed that unsupervised co-deviancy was predictive of an increase in marijuana use one year later. Neither process predicted an increase in alcohol use. Results did not differ as a function of gender.

Child and adolescent risk factors that differentially predict violent versus nonviolent crime.

While most research on the development of antisocial and criminal behavior has considered nonviolent and violent crime together, some evidence points to differential risk factors for these separate types of crime. The present study explored differential risk for nonviolent and violent crime by investigating the longitudinal associations between three key child risk factors (aggression, emotion dysregulation, and social isolation) and two key adolescent risk factors (parent detachment and deviant peer affiliation) predicting violent and nonviolent crime outcomes in early adulthood. Data on 754 participants (46% African American, 50% European American, 4% other; 58% male) oversampled for aggressive-disruptive behavior were collected across three time points. Parents and teachers rated aggression, emotion dysregulation, and social isolation in fifth grade (middle childhood, age 10-11); parents and youth rated parent detachment and deviant peer affiliation in seventh and eighth grade (early adolescence, age 12-14) and arrest data were collected when participants were 22-23 years old (early adulthood). Different pathways to violent and nonviolent crime emerged. The severity of child dysfunction in late childhood, including aggression, emotion dysregulation, and social isolation, was a powerful and direct predictor of violent crime. Although child dysfunction also predicted nonviolent crime, the direct pathway accounted for half as much variance as the direct pathway to violent crime. Significant indirect pathways through adolescent socialization experiences (peer deviancy) emerged for nonviolent crime, but not for violent crime, suggesting adolescent socialization plays a more distinctive role in predicting nonviolent than violent crime. The clinical implications of these findings are discussed.

The Biological Treatment of Paraphilic Disorders: an Updated Review.

Paraphilic disorders are characterized by atypical sexual interests, fantasies, and behaviors that are subjectively distressing to patients or pose a risk of harm to others. By their very nature, some paraphilic disorders may predispose an individual to commit sexual offenses. The biological treatment of paraphilic disorders, then, is of paramount importance for psychiatry and society at large. Three categories of pharmacologic agents commonly used to treat paraphilic disorders are selective serotonin reuptake inhibitors, synthetic steroidal analogs, and gonadotropin-releasing hormone analogs. Each medication uses a different mechanism of action and has different effects on the physiological and psychological features of paraphilic disorders. In general, these medications have limited high-quality research to support their use. Despite this, some authors have proposed treatment algorithms for individuals with paraphilic disorders of varying severity. These guidelines offer clinicians potentially useful, rational approaches to assessing treatment need in individuals with paraphilic disorders. Recent neuroimaging research suggests that functional magnetic resonance imaging may offer further promise in effectively assessing paraphilic disorders to help direct treatment options.

Changing Friend Selection in Middle School: A Social Network Analysis of a Randomized Intervention Study Designed to Prevent Adolescent Problem Behavior.

Adolescent friendships that promote problem behavior are often chosen in middle school. The current study examines the unintended impact of a randomized school-based intervention on the selection of friends in middle school, as well as on observations of deviant talk with friends 5 years later. Participants included 998 middle school students (526 boys and 472 girls) recruited at the onset of middle school (age 11-12 years) from three public middle schools participating in the Family Check-up model intervention. The current study focuses only on the effects of the SHAPe curriculum-one level of the Family Check-up model-on friendship choices. Participants nominated friends and completed measures of deviant peer affiliation. Approximately half of the sample (n = 500) was randomly assigned to the intervention, and the other half (n = 498) comprised the control group within each school. The results indicate that the SHAPe curriculum affected friend selection within school 1 but not within schools 2 or 3. The effects of friend selection in school 1 translated into reductions in observed deviancy training 5 years later (age 16-17 years). By coupling longitudinal social network analysis with a randomized intervention study, the current findings provide initial evidence that a randomized public middle school intervention can disrupt the formation of deviant peer groups and diminish levels of adolescent deviance 5 years later.

Sibling influence on mexican-origin adolescents' deviant and sexual risk behaviors: the role of sibling modeling.

PURPOSE: A growing body of research indicates that siblings uniquely influence each other's health risk behaviors during adolescence and young adulthood. Mechanisms underlying these associations, however, are largely unknown because they are rarely tested directly. The present study addressed this gap by examining the role of sibling modeling in explaining changes in Mexican-origin youths' deviant and sexual risk behaviors over time. METHODS: The sample included 380 Mexican-origin siblings (older sibling age: M = 21.18, SD = 1.59; younger sibling age: M = 18.19, SD = .46) from (N = 190) families. Participants provided self-reports of their sibling relationship qualities, including modeling, as well as their engagement in deviant and sexual risk-taking behaviors in two home interviews across a 2-year span. RESULTS: A series of residualized regression models revealed that younger siblings' perceptions of modeling moderated the links between older siblings' deviant and sexual risk behaviors and younger siblings' subsequent behaviors in those same domains. Specifically, high levels of modeling predicted stronger associations between older siblings' earlier and younger siblings' later risk behaviors controlling for younger siblings' earlier behaviors as well as variables that have been used as proxies for social learning in previous research. CONCLUSIONS: Social learning mechanisms, especially modeling, are salient processes through which older siblings transmit norms and expectations regarding participation in health risk behaviors. Future research should continue to explore the ways in which siblings influence each other because such processes are emerging targets for intervention and prevention.

Relationship between factors as sensation seeking, general self-efficacy and deviant peers with refusal skills among middle school students / 中华流行病学杂志

Objective To explore the relationship of sensation seeking,self-efficacy,deviant peers and refusal skills related to strategy on drugs among middle school students.Methods A total of 502 students from two high schools and two vocational schools in Baise city were recruited with age distribution between 14 and 20 years.The study objects were asked to fill the sensation seeking scale,the general self-efficacy scale questionnaire on drug refusal strategies and behavior among peers.Results ( 1 ) Adolescents were more likely to use the Refuse (78.29％) and Leave strategy (77.89％) for initial drug offers and follow-up drug offers; (2)The general self-efficacy was negatively associated with the Explain and Leave strategies for initial drug offers and Explain strategy for follow-up drug offers.Sensation seeking was negatively related to the strategies on Explain and Leave for initial drug offers and follow-up drug offers.Peer influence was positively associated with both Refuse and Leave strategies for initial drug offers and follow-up drug offers; (3)Results from the logistic regression analysis showed that self-efficacy and sensation seeking were significant variables that could predict the results from the use of Explain strategy (β =-0.055 and -0.029 ) for both initial drug refusals and follow-up drug refusals and the use of Leave strategy(β =-0.057 and-0.041 ) for initial drug refusals.Conclusion There were significant effects of sensation seeking and self-efficacy in predicting Explain or Leave strategies for drug refusals among middle students.

Unsettled women.

SUMMARY Amy Bock (alias Percy Redwood) created a media sensation when "The Case of the Woman Bridegroom" hit the newspapers throughout New Zealand in 1909. She was hailed as the "queerest and most interesting character that has ever been before the New Zealand public" and "pitiable in her freakish exploits." Debates ensued as to whether her crimes were evidence of a mania, a disease, or simply due to a flawed, criminal character. This article focuses on media portrayals of women who did not conform to normative constructions of acceptable womanhood within the latter decades of the nineteenth century and the early twentieth century in New Zealand, as a means of tracing the mutable boundaries of intelligible genders. Newspaper debates and emergent discourses around the medicalisation of social de-viancy are drawn upon to demonstrate how normative constructions of gender were premised upon a defining matrix of mad/bad/woman.
