Strengths use and deficit improvement: The relationship with engagement and fit with study course amongst first-year students

This study sought to test a model of students’ proactive behaviour to use their strengths and improve their deficits and how this relates with their self-reported perceptions of their fit with a study course and engagement. Participants were 692 first-year students from a higher education institution in South Africa (females=60.3%; blacks=71.3%; mean age=19.71; SD=1.93). They completed measures of strengths use, deficit improvement, perceptions of fit with a study course and engagement. Structural equation modelling was utilised to examine the relationship between students’ strengths use and deficit improvement, perceptions of fit with a study course and student engagement. In addition, the bootstrapping method was used to identify possible mediating effects of fit with a study course. The results indicated that only deficit improvement showed a significant relationship with engagement. Perceptions of fit with a study course mediated the relationship between students’ strengths use and deficit improvement.     

Reflective journaling: fostering dispositional development in preservice teachers

This study investigated the self-identified dispositions of 183 preservice teachers enrolled in a required philosophy of education course. The researchers coded their reflective journaling for the two essential NCATE (National Council for Accreditation of Teacher Education) dispositions of fairness and the belief that all students can learn, as well as for other recurring, self-identified dispositions. These preservice teachers self-identified fairness much more frequently than the belief that all students can learn. The results point to additional recurring dispositional themes for consideration: critical thinking, caring, openness, moral education, and individual freedom. Further examination of the data revealed great variation in the preservice teachers’ interpretation of fairness, categorized as fairness through (1) inclusion of all socioeconomic classes and abilities; (2) culturally responsive teaching; (3) differentiation of instruction; and (4) fostering a safe learning environment.     

Advice seeking and loaning of money related to relapse in recovery homes

Recovery homes help individuals who have completed substance use treatment programs re‐integrate back into the community. However, it is unclear what factors determine who will succeed in these settings and how these factors may be reinforced or undermined by the social interactions and social networks between residents living in the Oxford House recovery homes. In an effort to better understand these factors, the current study evaluated (a) the extent to which the density of social networks (i.e., friendship, willingness to loan money, and advice‐seeking relationships) is associated with social capital (i.e., sense of community, quality of life, hopefulness, self‐efficacy), and (b) whether the density of social networks predicts relapse over time. Among the findings, willingness to loan money was positively associated with all four individual‐level social capital variables, suggesting that availability of instrumental resources may be important to ongoing recovery. To test whether these house‐level social network factors then support recovery, a survival analysis was conducted, finding associations between relapse risk and the network densities over a 28‐month span. In particular, more dense advice‐seeking networks were associated with higher rates of relapse, suggesting that the advice‐seeking might represent a sign of organisational house problems, with many residents unsure of issues related to their recovery. In contrast, more dense loaning networks were associated with less relapse, so willingness to lend money could be measuring a willingness to help those in need. The implications of these findings are discussed.     

Neurocognitive outcomes in children with unilateral basal ganglia arterial ischemic stroke and secondary hemidystonia

Dystonia is a movement disorder that involves excessive, involuntary muscle contractions resulting in repetitive movements and/or abnormal posturing. One common cause of unilateral dystonia in childhood is ischemic stroke involving the basal ganglia and/or thalamus. Virtually nothing is known about neuropsychological outcomes in children who have dystonia following basal ganglia stroke. The present study explored whether or not children with secondary dystonia experience additional cognitive challenges when compared to children with similar patterns of brain injury, but no dystonia. We examined intellectual function, academics, and several aspects of executive function in children with unilateral basal ganglia stroke during childhood, comparing those with dystonia and those without. Although groups did not differ in terms of lesion size, we found significantly lower performance on measures of verbal and nonverbal reasoning, inhibitory control, and academic ability in children with secondary dystonia compared to those without. In contrast, there were no significant group differences on parent ratings of their child’s executive function in daily life. These findings suggest that maladaptive reorganization following basal ganglia stroke may contribute to the development of secondary dystonia and also to poor intellectual and academic outcomes in this group.     

Children's natural conversations following exposure to a rumor: Linkages to later false reports

Previous research has shown that children naturally propagate overheard false rumors and that the circulation of such information can induce children and their peers to wrongly recall actually experiencing rumored-but-nonexperienced events. The current study extends this work by recording 3- to 6-year-olds' naturally occurring conversations following exposure to an erroneous rumor. Results indicate that, compared with children who overhear rumors spread by adults, those who pick up rumors from peers during natural interactions engage in deeper and more inventive rumor mongering. Moreover, the degree and originality of rumor propagation was linked with various qualities of children's subsequent recollections at both 1-week and 4-week delayed interviews. Furthermore, compared with 3- and 4-year-olds, 5- and 6-year-olds naturally transmitted more novel and coherent embellishments of the rumor to their peers, and more of their false narrative reports during the interviews overlapped with their own and their peers' utterances transmitted soon after the rumor was planted.     

Effects of mothers’ conversation style and receipt of misinformation on children's event reports

Can memory sharing conversations with mothers lead to errors in children's event memory when mothers are exposed to misinformation about what their children experienced and does this effect vary as a function of maternal memory-sharing style? Mothers were exposed to a false suggestion about a non-shared event and then discussed that event with their children. When later interviewed, those children whose mothers were provided this misinformation were likely to wrongly report experiencing activities consistent with the maternal suggestion and embellish their reports of these activities with elaborative detail. Moreover, children whose mothers spoke in a highly elaborative manner were more likely to recall occurrences in line with the maternal suggestion and provided more fictitious narrative detail describing non-occurring-but-suggested information than did children whose mothers used a less elaborative style. These findings suggest that when mothers hold false beliefs about a non-shared event, an elaborative maternal style is associated with an increase in children's false reports reflecting maternal beliefs.     

Dichotic listening performances in the follow-up of Landau and Kleffner syndrome

Abstract

In the follow-up study of 4 children with acquired epileptic aphasia or Landau and Kleffner syndrome, dichotic listening studies evidenced a unilateral ear extinction. In the four cases, the dichotic extinction was contralateral to the temporal cortex involved in the generation of epileptic discharges during the active period of epilepsy. This pattern of dichotic performances persisted several years after the complete recovery from epilepsy and EEG normalization. The long-lasting dichotic extinction revealed a permanent dysfunction in the temporal auditory system that may be a consequence of the presence of an active epileptogenic focus during the critical period of functional differentiation of the temporal cortex.     

Seeing Things Unseen: Fantasy Beliefs and False Reports

Whereas past research has demonstrated that children's beliefs about the real world can influence their memory for events, the role of fantasy beliefs in children's recall remains largely unexplored. We examine this topic in 5- and 6-year-olds by focusing on how belief in a familiar fantasy figure, namely the Tooth Fairy, is related to children's memory for their most recent primary tooth loss. Although children who fully believed in the reality of the Tooth Fairy provided more voluminous and complex accounts than those with less strong beliefs, they also provided the most fictitious reports, frequently characterized by claims of hearing or seeing the Tooth Fairy. Belief in the Tooth Fairy did not affect the accuracy of children's reports of the mundane elements of their tooth loss, and many fantastic claims were linked to real events. Exposure to seemingly tangible evidence of the Tooth Fairy's existence was associated with the provision of fantastic claims.     

Testing take-the-best in new and changing environments

Take-the-best is a decision-making strategy that chooses between alternatives, by searching the cues representing the alternatives in order of cue validity, and choosing the alternative with the first discriminating cue. Theoretical support for take-the-best comes from the “fast and frugal” approach to modeling cognition, which assumes decision-making strategies need to be fast to cope with a competitive world, and be simple to be robust to uncertainty and environmental change. We contribute to the empirical evaluation of take-the-best in two ways. First, we generate four new environments—involving bridge lengths, hamburger prices, theme park attendances, and US university rankings—supplementing the relatively limited number of naturally cue-based environments previously considered. We find that take-the-best is as accurate as rival decision strategies that use all of the available cues. Secondly, we develop 19 new data sets characterizing the change in cities and their populations in four countries. We find that take-the-best maintains its accuracy and limited search as the environments change, even if cue validities learned in one environment are used to make decisions in another. Once again, we find that take-the-best is as accurate as rival strategies that use all of the cues. We conclude that these new evaluations support the theoretical claims of the accuracy, frugality, and robustness for take-the-best, and that the new data sets provide a valuable resource for the more general study of the relationship between effective decision-making strategies and the environments in which they operate.     

Working memory outcomes following unilateral arterial ischemic stroke in childhood

There is a dearth of research examining working memory (WM) following pediatric arterial ischemic stroke (AIS). This study assesses the WM patterns of 32 children, aged 6 to 14 years, with a history of unilateral AIS and 32 controls using a paradigm based on Baddeley and Hitch’s multi-component WM model. The results indicate compromised WM in children with AIS relative to controls and parent reports confirm higher rates of dysfunction. Supplementary analyses of impairment confirm higher rates in children with AIS, ranging from 31.25% to 38.70% on performance-based measures and 50.00% on parent reports, compared to 0.00% to 21.88% on performance-based measures in controls and 15.63% on parent reports. Continual follow-up is recommended given that a subset of children with stroke appear to be at risk for WM impairment. Moreover, the subtle nature of WM challenges experienced by many children who have experienced a stroke increases the likelihood that WM impairment could go undetected. The long-term trajectories of WM in the pediatric stroke population remains unknown and future studies are needed to track changes in WM functioning over time.
