Children's understanding of the earth in a multicultural community: mental models or fragments of knowledge?

Children's understanding of properties of the earth was investigated by interviewing Asian and white British classmates aged 4?8 years (N = 167). Two issues were explored: whether they held mental models of the earth ( Vosniadou & Brewer, 1992 ) or instead had fragmented knowledge ( di Sessa, 1988 ); and the influence of the children's different cultural backgrounds. Children selected from a set of plastic models and answered forced‐choice questions. Using this methodology, there were no significant differences in the overall performance of Asian and white children after language skills were partialled out. Even young children showed an emerging knowledge of some properties of the earth, but the distributions of their combinations of responses provided no evidence that they had mental models. Instead, these distributions closely resembled those that would be expected if children's knowledge in this domain were fragmented. Possible reasons for the differences between these findings and those of previous research are discussed.     

Challenges for aging Holocaust survivors and their children: The impact of early trauma on aging

ABSTRACT

Is the impact of early trauma continually present or does the negative psychological impact disappear when survivors are younger and then reappear as they age? In Transcending Trauma Project interviews survivors noted the impact of the Holocaust was always present but some stated that it increased as they aged. A small number of children of survivors interviewed observed a dependence upon defense mechanisms to cope with aging which differed from the survivors’ identification of using active and family coping strategies during the war and postwar years. Though children who experienced positive parent-child relationships mentioned the negative coping strategies, they also spoke positively of the impact of their parents in their own lives and expressed empathy for their parents. In the families where tensions existed between the survivors and their children, the children did not express empathy for their aging parents. Several studies supported the importance of family relationships in the aging process. This secondary analysis study further explored the impact of the Holocaust in aging survivors and the views of some children of survivors on aging.     

Transdiagnostic internet treatment for anxiety and depression: a randomised controlled trial

Disorder-specific cognitive behavioural therapy programs delivered over the internet (iCBT) with clinician guidance are effective at treating specific anxiety disorders and depression. The present study examined the efficacy of a transdiagnostic iCBT protocol to treat three anxiety disorders and/or depression within the same program (the Wellbeing Program). Seventy-seven individuals with a principal diagnosis of major depression, generalised anxiety disorder, panic disorder, and/or social phobia were randomly assigned to a Treatment or Waitlist Control group. Treatment consisted of CBT-based online educational lessons and homework assignments, weekly email or telephone contact from a clinical psychologist, access to a moderated online discussion forum, and automated emails. Eighty one percent of Treatment group participants completed all 8 lessons within the 10 week program. Post-treatment data were collected from 34/37 Treatment group and 35/37 Control group participants, and 3-month follow-up data were collected from 32/37 Treatment group participants. Relative to Controls, Treatment group participants reported significantly reduced symptoms of anxiety and depression as measured by the Depression Anxiety and Stress Scales-21 item, Patient Health Questionnaire-9 item, and Generalised Anxiety Disorder-7 item scales, with corresponding between-groups effect sizes (Cohen’s d) at post treatment of.56,.58, and.52, respectively. The clinician spent a mean time of 84.76 min (SD = 50.37) per person over the program. Participants rated the procedure as highly acceptable, and gains were sustained at follow-up. These results provide preliminary support for the efficacy of transdiagnostic iCBT in the treatment of anxiety and depressive disorders.     

Negative affectivity and drug use in adolescent boys: moderating and mediating mechanisms

This investigation examined variables that might qualify or detail the widely accepted relation between negative affectivity and drug use in adolescent boys. In Study 1, 311 boys (15-17 years old) completed inventories of negative affectivity, positive affectivity, constraint, delinquency, peer delinquency, and drug use. Negative affectivity was positively related to drug use, but only for individuals exhibiting high peer delinquency or low constraint. Study 2 examined mechanisms for this relation by following up 143 of the participants at ages 17-20 years. Delinquency and peer delinquency mediated the relation between negative affectivity and later drug use. These findings suggest that the relation between negative affectivity and drug use is best understood within the context of other drug use risk factors.

Fixed-target efficient search has logarithmic efficiency with and without eye movements

Stage 1 processing in visual search (e.g., efficient search) has long been thought to be unaffected by factors such as set size or lure–distractor similarity (or at least to be only minimally affected). Recent research from Buetti, Cronin, Madison, Wang, and Lleras (Journal of Experimental Psychology: General, 145, 672–707, 2016) showed that in efficient visual search with a fixed target, reaction times increase logarithmically as a function of set size and, further, that the slope of these logarithmic functions is modulated by target–distractor similarity. This has led to the proposal that the cognitive architecture of Stage 1 processing is parallel, of unlimited capacity, and exhaustive in nature. Such an architecture produces reaction time functions that increase logarithmically with set size (as opposed to being unaffected by it). However, in the previous studies, eye movements were not monitored. It is thus possible that the logarithmicity of the reaction time functions emerged simply as an artifact of eye movements rather than as a reflection of the underlying cognitive architecture. Here we ruled out the possibility that eye movements resulted in the observed logarithmic functions, by asking participants to keep their eyes at fixation while completing fixed-target efficient visual search tasks. The logarithmic RT functions still emerged even when participants were not allowed to make eye movements, thus providing further support for our proposal. Additionally, we found that search efficiency is slightly improved when eye movements are restricted and lure–target similarity is relatively high.
