The Influences of Category Learning on Perceptual Reconstructions

We explore different ways in which the human visual system can adapt for perceiving and categorizing the environment. There are various accounts of supervised (categorical) and unsupervised perceptual learning, and different perspectives on the functional relationship between perception and categorization. We suggest that common experimental designs are insufficient to differentiate between hypothesized perceptual learning mechanisms and reveal their possible interplay. We propose a relatively underutilized way of studying potential categorical effects on perception, and we test the predictions of different perceptual learning models using a two-dimensional, interleaved categorization-plus-reconstruction task. We find evidence that the human visual system adapts its encodings to the feature structure of the environment, uses categorical expectations for robust reconstruction, allocates encoding resources with respect to categorization utility, and adapts to prevent miscategorizations.     

Mothers speak differently to infants at‐risk for dyslexia

Dyslexia is a neurodevelopmental disorder manifested in deficits in reading and spelling skills that is consistently associated with difficulties in phonological processing. Dyslexia is genetically transmitted, but its manifestation in a particular individual is thought to depend on the interaction of epigenetic and environmental factors. We adopt a novel interactional perspective on early linguistic environment and dyslexia by simultaneously studying two pre‐existing factors, one maternal and one infant, that may contribute to these interactions; and two behaviours, one maternal and one infant, to index the effect of these factors. The maternal factor is whether mothers are themselves dyslexic or not (with/without dyslexia) and the infant factor is whether infants are at‐/not‐at family risk for dyslexia (due to their mother or father being dyslexic). The maternal behaviour is mothers’ infant‐directed speech (IDS), which typically involves vowel hyperarticulation, thought to benefit speech perception and language acquisition. The infant behaviour is auditory perception measured by infant sensitivity to amplitude envelope rise time, which has been found to be reduced in dyslexic children. Here, at‐risk infants showed significantly poorer acoustic sensitivity than not‐at‐risk infants and mothers only hyperarticulated vowels to infants who were not at‐risk for dyslexia. Mothers’ own dyslexia status had no effect on IDS quality. Parental speech input is thus affected by infant risk status, with likely consequences for later linguistic development.     

Daily Peer Hassles and Non-Suicidal Self-Injury in Adolescence: Gender Differences in Avoidance-Focused Emotion Regulation Processes

This study aimed to examine the mediating role of rumination, experiential avoidance, dissociation and depressive symptoms in the association between daily peer hassles and non-suicidal self-injury among adolescents. Additionally, this study explored gender differences in these associations and tested whether the proposed model was invariant across genders. The sample consisted of 776 adolescents, of them 369 are males (47.6%) and 407 are females (52.4%), aged between 12 and 18 years old from middle and high schools in Portugal. Participants completed self-report questionnaires to assess daily peer hassles, rumination in its severe component (i.e., brooding), experiential avoidance, dissociation, depressive symptoms and non-suicidal self-injury. Path analysis showed that daily peer hassles indirectly impact on non-suicidal self-injury through increased levels of brooding, experiential avoidance, dissociation, and depressive symptoms. Results indicated significant gender differences in mean scores and path analysis. Male adolescents were more likely to engage in brooding and experiential avoidance in response to external distress (particularly, daily peer hassles), whereas female adolescents were more likely to engage in non-suicidal self-injury in response to internal distress (particularly, depressive symptoms). These findings suggest relevant preventive and intervention actions to address emotion dysregulation in adolescence, by teaching them acceptance and mindfulness skills as a way of coping with stressful experiences and internal distress.     

Deradicalizing Detained Terrorists

Deradicalization of terrorists constitutes a critical component of the global “war on terror.” Unfortunately, little is known about deradicalization programs, and evidence for their effectiveness is derived solely from expert impressions and potentially flawed recidivism rates. We present the first empirical assessment of one such program: the Sri Lankan rehabilitation program for former members of the Liberation Tigers of Tamil Eelam (a terrorist organization that operated in Sri Lanka until their defeat in 2009). We offer evidence that deradicalization efforts that provided beneficiaries with sustained mechanisms for earning personal significance significantly reduced extremism after 1 year (Study 1). We also found that upon release, beneficiaries expressed lower levels of extremism than their counterparts in the community (Study 2). These findings highlight the critical role of personal significance in deradicalization efforts, offer insights into the workings of deradicalization, and suggest practical methods for improving deradicalization programs worldwide.     

Cultural identity dynamics: Capturing changes in cultural identities over time and their intraindividual organization

Important life transitions – such as migration – have the potential to enrich one's sense of self, but they are also demanding and challenging. The current research investigates how cultural identities change and become configured over time among newly arrived international students and the social factors that predict these longitudinal changes. A four‐wave longitudinal study was conducted during international students' first year in their new country (N = 278). Multivariate hierarchical linear modeling analyses allowed us to unpack both baseline (between‐person) and intraindividual change (within‐person) effects. Whereas increased psychological need satisfaction via both the new and one's heritage cultural group predicted increased identity integration, greater discrimination (i.e., both at baseline and an increase over time) predicted increased compartmentalization and the predominance (categorization) of one identity over the others. Results are discussed in light of novel theoretical developments in the acculturation and identity change literatures.     

Like Father,like Child: Early Life Family Adversity and Children’s Bullying Behaviors in Elementary School

Family adversity has been associated with children’s bullying behaviors. The evidence is, however, dominated by mothers’ perceptions of the family environment and a focus on mothers’ behaviors. This prospective population-based study examined whether children’s bullying behaviors were associated with mother- and father-reported family adversity, assessed before and after child birth. Peer-nominations were used to assess bullying behaviors of 1298 children in elementary school (mean age 7.5 years). The following paternal risk factors were prospectively associated with children’s bullying behaviors: (1) father-reported prenatal family distress, (2) fathers’ hostility at preschool age, and (3) fathers’ harsh disciplinary practices at preschool age, but effect sizes were relatively small. The effect of maternal risk factors was less consistent, only mother-reported family distress in childhood was associated with children’s bullying behaviors. The associations were independent of background family risk factors (i.e., life stress, contextual factors, and other background factors such as parental education and risk taking record) and early childhood externalizing problems. Moreover, our results indicated that father-reported family adversity predicted children’s bullying behaviors over and above the background family risk factors, early childhood externalizing problems and mother-reported family adversity. We also demonstrated that the association of fathers’ prenatal hostility and family distress with subsequent bullying behavior of their child at school was partly mediated by fathers’ harsh disciplinary practices at preschool age. Our findings highlight the importance of fathers’ behaviors in the development of children’s bullying behaviors.     

Fear of missing out: prevalence,dynamics, and consequences of experiencing FOMO

Fear of missing out, known colloquially as FOMO, appears to be a common experience, and has recently become part of the vernacular, receiving frequent mentions in the popular media. The present paper provides a multi-method empirical examination of FOMO. In a first study, experience sampling was used to assess FOMO experiences among college freshmen. Nightly diaries and end-of-semester measures provided data on the short and long-term consequences of experiencing FOMO. Results showed that students experience FOMO frequently, particularly later in the day and later in the week, and while doing a required task like studying or working. More frequent experiences of FOMO were associated with negative outcomes both daily and over the course of the semester, including increasing negative affect, fatigue, stress, physical symptoms, and decreased sleep. A second experimental study investigated FOMO on a conceptual level, distinguishing FOMO from general self-regulation and exploring its links with social media.     

Temporality in Psychosis: Loss of Lived Time in an Alien World

This article presents a model of the temporal structure of psychic life. Time is a rule-guided process. A person's psychic life, too, yields to an examination of necessary and regulated operations. To outline both the regular and the modified perception of time within psychic life, Sigmund Freud's model of the drive interaction is brought to bear on Jacques Marie Émile Lacan's understanding of psychosis. Both Freud's and Lacan's findings are explained with an eye on the temporal dimension of the psyche, temporal modifications manifested in states of psychotic delusion, and the role of time for one's meaningful engagement with the world. Psychic time is nonlinear. The future, the past, and the present must be engaged simultaneously, albeit not in the same way, to yield the sense of temporal fullness. For Freud, the cooperative functioning of the drives accounts for the sustainment of the lucid psychic life, whereas modifications in the drives’ interactions signal psychic disturbances. Lacan (1955/1993) stresses the atemporal character of the nonexistent, negated, or lost reality that pressures an individual to enter a psychotic delusion. This article makes the assumption that the psychological states in which the reckoning with time is lost are the consequences of an unsuccessful incorporation of traumatic stimuli that are caused both by outside phenomena and by the actions of an individual's inner drives. The findings of this article support the view that psychic traumas necessitate modifications to the sense of time. The findings also offer an understanding of the kinds of temporal modifications that occur in an individual's psychic life and the way in which these temporal changes lead to the experience of radical otherness that is present in some cases of psychological disturbances.
