Age-Correlated Incremental Consideration of Velocity Information in Relative Time-to-Arrival Judgments

One hundred fifty-one children and 43 adults judged which of 2 cartoon birds would be the first to arrive at a common finish line. Objects moved unidirectionally along parallel trajectories, either at the same or different speeds, and disappeared at different distances from the goal. Overall, 9–10-year-old children performed as well as adults, but 4–5- and 6–8-year-olds erred significantly more often. On trials for which distance to goal at disappearance was a valid cue, 4–5-year-olds scored 80% correct, and no differences were seen between 6–10-year-olds and adults. On the opposite type of trials, where the trailing bird would win the race, only adults retained their level of performance, and all age groups differed markedly. Findings suggest a gradual developmental transition from a distance-based to a time-based understanding of the task.     

“Shrink Rap” on the Air,Mentalizing in the Last Frontier

This paper highlights the author's approach to expand the process of mentalizing in a rural Alaskan town. Limited resources and a steady flow in cases of trauma, loss, and abuse prompted the question, “What treatment approach would facilitate healing and the promotion of security?” The author illustrates how a unique culture and independent, frontier-minded individuals influenced her use of a systems and psychoeducational approach. Psychoanalytic concepts, attachment research, and mentalization became the guiding principles for weekly broadcasts of Shrink Rap, a radio show including “relational scenarios” acted and analyzed by the author and community participants.     

The effect of mindfulness meditation on time perception

Research has increasingly focussed on the benefits of meditation in everyday life and performance. Mindfulness in particular improves attention, working memory capacity, and reading comprehension. Given its emphasis on moment-to-moment awareness, we hypothesised that mindfulness meditation would alter time perception. Using a within-subjects design, participants carried out a temporal bisection task, where several probe durations are compared to “short” and “long” standards. Following this, participants either listened to an audiobook or a meditation that focussed on the movement of breath in the body. Finally, participants completed the temporal bisection task for a second time. The control group showed no change after the listening task. However, meditation led to a relative overestimation of durations. Within an internal clock framework, a change in attentional resources can produce longer perceived durations. This meditative effect has wider implications for the use of mindfulness as an everyday practice and a basis for clinical treatment.     

Toddlers' Social Behaviors in Dyads and Groups

Although toddlers are clearly capable of interacting with peers, the amount and type of interactions among toddlers is controversial. Objectives of the present study were (a) to determine the effect of dyad versus group settings on the amount and type of social behaviors with peers, (b) to determine preference for interacting with peers versus adults, and (c) to determine differences in the types of behaviors directed to peers and adults. Sixteen children (with a mean age of 27 months) were observed in both a group setting and a dyad setting; their mothers were present in both settings. The children were from three different toddler classes, each meeting once a week. Specific social behaviors were coded, as well as the person to whom the behavior was directed (i.e., peer or adult). Setting affected toddlers' behaviors with adults but not behaviors with peers. Regardless of setting, toddlers preferred interacting with adults. The types of behaviors directed to peers and adults differed. Direct interactions with peers were rare, but interest and awareness of peers was shown by moderately high levels of proximity and parallel play. The use of different criteria to define social play appears to account for differences across studies in the amount of peer interaction.     

A validation of a computerised task of risk-taking and moral decision-making and its association with sensation-seeking,impulsivity and sociomoral reasoning

The aim of this study was to investigate the reliability and validity of the computer based application of the Secret Agent (SA) task of risk-taking and moral decision-making. The participants were 100 male patients in a maximum security hospital (50 with severe mental illness and 50 with personality disorder) and 50 community based healthy controls. All participants completed the SA task, the Iowa Gambling Task (IGT), and measures of IQ, antisocial personality traits, sensation-seeking, impulsivity and sociomoral reasoning. The SA risk-taking and moral decision-making scales had satisfactory levels of reliability (Cronbach’s alpha). Risk-taking correlated significantly with sensation-seeking across all three participant groups. In contrast, risk-taking only correlated with impulsivity among the severe mental illness group. Moral decision-making correlated with sociomoral reasoning among the personality disorder group. No correlation was found between the SA scores and the IGT score and the IGT did not correlate with sensation-seeking or impulsivity. IQ and antisocial personality traits did not correlate with the SA or IGT scales. The study highlights the importance of context, the nature of the risk-taking task, and ‘problem framing’ of the instructions in their relationship with individual differences.     

Fostering Students’ Appraisals of the Relevance of History by Comparing Analogous Cases of an Enduring Human Issue: A Quasi-Experimental Study

To identify the challenges that students must meet to engage in effective self-directed inquiry, a class was followed for three years, from the fourth through the sixth grades, as they engaged in a sequence of progressively more demanding inquiry activities. Students made substantial progress in understanding the objectives of inquiry, identifying questions, attending to evidence, identifying patterns, making controlled comparisons, interpreting increasingly complex data, supporting claims, and drawing justified conclusions. Retaining awareness of inquiry objectives and integrating influences of multiple variables in predicting outcomes were two areas that remained challenging. A comparison group of seventh graders who had not been involved in the program displayed strikingly different approaches to an inquiry task, indicating that the skills identified here are not ones that develop in the absence of appropriate kinds of educational experiences.
