Effect of anxiety on behavioural pattern separation in humans

Behavioural pattern separation (BPS), the ability to distinguish among similar stimuli based on subtle physical differences, has been used to study the mechanism underlying stimulus generalisation. Fear overgeneralisation is often observed in individuals with posttraumatic stress disorder and other anxiety disorders. However, the relationship between anxiety and BPS remains unclear. The purpose of this study was to determine the effect of anxiety (threat of shock) on BPS, which was assessed across separate encoding and retrieval sessions. Images were encoded/retrieved during blocks of threat or safety in a 2?×?2 factorial design. During retrieval, participants indicated whether images were new, old, or altered. Better accuracy was observed for altered images encoded during periods of threat compared to safety, but only if those images were also retrieved during periods of safety. These results suggest that overgeneralisation in anxiety may be due to altered pattern separation.     

Self-Regulation in the Classroom: A Perspective on Assessment and Intervention

Il n’y a pas de définition simple et univoque du concept d’apprentissage autorégulé. Des théoriciens de psychologie de l’éducation ont réduit l’éventail des aptitudes des élèves à s’autoréguler en se focalisant sur le versant scolaire de l’éducation, à savoir l’acquisition des connaissances et les objectifs de réussite. Toutefois, le monde complexe de l’étude en classe engendre une situation où différents buts entrent en concurrence aux yeux des élèves. Le modèle d’autorégulation à double processus de Bookaerts montre que les deux objectifs que sont l’étude et le bien‐être interagissent. Nous estimons que lorsque les élèves ont accès à des stratégies autonomes bien au point se traduisant par de bonnes habitudes de travail, ils ont une plus grande probabilité de se motiver pour les études et de sauvegarder leur bien‐être quand une source de stress bloque l’apprentissage. There is no simple and straightforward definition of the construct of self‐regulated learning. Theorists in educational psychology have narrowed the scope of students’ capability to self‐regulate through a focus on the academic side of education, namely on learning and achievement goals. However, the messy world of classroom learning creates a situation in which different goals compete for students’ attention. Boekaerts’ dual processing self‐regulation model describes how learning goals interact with well‐being goals. We propose that when students have access to well‐refined volitional strategies manifested as good work habits, they are more likely to invest effort in learning and get off the well‐being track when a stressor blocks learning. Shifting definitions of SRL have led to changing measurement procedures; researchers moved away from decontextualised measures of SRL to domain‐specific measures and then on to context‐sensitive measures. The validity and reliability of the first generation of SR assessment has been limited and several issues remain. Recently, researchers have designed assessment packages including new instruments that better capture self‐regulation as a process (including for example traces of mental events, situational manipulations, and records of student work strategies). A combination of instruments is preferable over a single instrument for assessing self‐regulation as a process and the effects of interventions to improve students’ self‐regulatory capacity. At present, many sound SRL interventions exist and some general lessons can be learned about classroom intervention research.     

Exploring Parent-Adolescent Communication About Gender: Results from Adolescent and Emerging Adult Samples

Although parents are assumed to be children's primary models of socialization when it comes to gender, little is known about direct communication of gendered values in the family. Accordingly, this study assessed the amount and content of recalled parental gender socialization messages using data from 291 U.S. college undergraduates attending a large Midwestern university and 259 U.S. adolescents enrolled in public high schools in the Midwest. The study examined the amount and content of parental communications of five gendered discourses and then tested for connections to current gender beliefs. Findings indicate that gender socialization may be quite similar for sons and daughters, with some evidence of gender typing in patterns of communication. No significant age differences emerged in the patterns of socialization, although high school students reported receiving greater amounts of communication than college students on two of the five discourses. In general, receiving messages promoting traditional gender roles was associated with more traditional gender beliefs (and vice versa), although interpretation of some messages appeared to vary by gender.     

The effect of induced anxiety on cognition: threat of shock enhances aversive processing in healthy individuals

Individuals with anxiety disorders demonstrate altered cognitive performance including (1) cognitive biases towards negative stimuli (affective biases) and (2) increased cognitive rigidity (e.g., impaired conflict adaptation) on affective Stroop tasks. Threat of electric shock is frequently used to induce anxiety in healthy individuals, but the extent to which this manipulation mimics the cognitive impairment seen in anxiety disorders is unclear. In this study, 31 healthy individuals completed an affective Stroop task under safe and threat-of-shock conditions. We showed that threat (1) enhanced aversive processing and abolished a positive affective bias but (2) had no effect on conflict adaptation. Threat of shock thus partially models the effects of anxiety disorders on affective Stroop tasks. We suggest that the affective state of anxiety—which is common to both threat and anxiety disorders—modulates the neural inhibition of subcortical aversive processing, whilst pathologies unique to anxiety disorders modulate conflict adaptation.     

Influences on employee perceptions of organizational work–life support: Signals and resources

This study examined predictors of employee perceptions of organizational work–life support. Using organizational support theory and conservation of resources theory, we reasoned that workplace demands and resources shape employees' perceptions of work–life support through two mechanisms: signaling that the organization cares about their work–life balance and helping them develop and conserve resources needed to meet work and nonwork responsibilities. Consistent with our hypotheses, we found that higher demands (work hours and work overload) were associated with reduced perceptions that the organization was supportive of work–life integration. Resources (job security, fit between employees' needs and the flexible work options available to them, supervisor support and work group support) were positively associated with perceptions of organizational work–life support. The results of this study urge further scholarly attention to work-based demands and resources as predictors of perceived organizational work–life support and yield implications for managerial practice.     

A preliminary study of medial temporal lobe function in youths with a history of caregiver deprivation and emotional neglect

Previous research findings have linked caregiver deprivation and emotional neglect with sensitivity to threatening cues. The present preliminary study investigated whether dysfunctions of the medial temporal lobe could underlie these associations. Using fMRI, we measured medial temporal lobe responses to emotional faces (angry, fearful, happy, neutral) among 30 youths. Eleven of the youths had a history of caregiver deprivation and emotional neglect. Attention states (i.e., attention to anger, fear, or physical attributes, or passive viewing) were systematically manipulated. Relative to comparison youths, youths with a history of caregiver deprivation and emotional neglect showed significantly greater left amygdala and left anterior hippocampus activation during the processing of threatening information. To our knowledge, these findings are the first to demonstrate altered medial temporal lobe function during the processing of threat cues in youths with a history of caregiver deprivation and emotional neglect.     

Family and career path characteristics as predictors of women’s objective and subjective career success: Integrating traditional and protean career explanations

This study examined the effects of family and career path characteristics on objective and subjective career success among 916 employed mothers. Among family variables, age at first childbirth was positively related and career priority favoring the husband was negatively related to both income and subjective career success; number of children was negatively related and years elapsed since first childbirth was positively related to income only. Among career path variables, career gaps, interorganizational mobility and proportion of one’s career spent in part-time work were negatively related to income; career gaps were negatively related to subjective career success. Income was positively related to subjective career success. Results suggest that integration of traditional and protean career perspectives helps to explain women’s career success.     

Uncertainty about perception and dissociation after compulsive-like staring: Time course of effects

Repeated and compulsive-like checking reduces confidence in memory for the last check. Obsessive-compulsive (OC) patients are not only uncertain about memory, but may also be uncertain about perception, while this perceptual uncertainty may be associated with prolonged visual fixation on the object of uncertainty. It was reported earlier that, among healthy participants, prolonged staring at light bulbs or gas rings induces OC-like uncertainty about perception and feelings of dissociation [van den Hout, M. A., Engelhard, I. M., de Boer, C., du Bois, A., & Dek, E. (2008). Perseverative and compulsive-like staring causes uncertainty about perception. Behaviour Research and Therapy, 46, 1300–1304]. In that study, staring continued for 10 min. For patients, however, staring intervals seem to be considerably shorter. To test the clinical credibility of the paradigm as a model of the maintenance of OC perceptual uncertainty, we investigated whether the effects of staring materialize long before 10 min. Five groups of 16 undergraduates participated: one group did not stare at a gas stove while the others stared for 7.5, 15, 30 or 300 s. In the absence of staring, no pre-to-post increase in dissociation/uncertainty was reported, but after staring it was. The larger part of the observed dissociation/uncertainty after 5 min had occurred within 30 s, and around 50% of this maximal increase was reported between 7.5 and 15 s. Thus, even relatively short intervals of staring induce uncertainty about perception and dissociative experiences. Perseverative looking at objects may be a counter-productive OC strategy, which increases uncertainty about perception and may serve to maintain the disorder.
