Effects of age,dysphoria, and emotion‐focusing on autobiographical memory specificity in children

Overgeneral autobiographical memory (OGM) is strongly associated with depression in adults and appears to reflect a stable cognitive bias. However, it is not known whether this bias exists in children or what factors contribute to its development. We examined the roles of age, dysphoria, and a new variable, emotion‐focusing (EF), on the production of specific autobiographical memory (AM) in children, using the standard Autobiographical Memory Test (AMT; Williams & Broadbent, 1986 Williams, JMG and Broadbent, K. (1986). Autobiographical memory in suicide attempters. Journal of Abnormal Psychology, 95: 144–149. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Results show that older children are more specific than younger children, irrespective of cue valence. Dysphoria was linked to less specific retrieval of positive memories in children. A three‐way interaction between age, valence, and dysphoria was also found, such that older dysphoric children demonstrated a difficulty in retrieving specific negative memories. In addition, emotion‐focusing was associated with specific AM recall, especially to negative cues. Results are discussed with reference to the development of depressogenic biases.     

The effects of action video game experience on the time course of inhibition of return and the efficiency of visual search

The ability to efficiently search the visual environment is a critical function of the visual system, and recent research has shown that experience playing action video games can influence visual selective attention. The present research examined the similarities and differences between video game players (VGPs) and non-video game players (NVGPs) in terms of the ability to inhibit attention from returning to previously attended locations, and the efficiency of visual search in easy and more demanding search environments. Both groups were equally good at inhibiting the return of attention to previously cued locations, although VGPs displayed overall faster reaction times to detect targets. VGPs also showed overall faster response time for easy and difficult visual search tasks compared to NVGPs, largely attributed to faster stimulus-response mapping. The findings suggest that relative to NVGPs, VGPs rely on similar types of visual processing strategies but possess faster stimulus-response mappings in visual attention tasks.     

The impact of verbal feedback about blushing on social discomfort and facial blood flow during embarrassing tasks

To investigate whether verbal feedback about blushing influences subsequent social discomfort or blushing itself, changes in facial blood flow and ratings of blushing and embarrassment were investigated in high (N=28) and low scorers (N=28) on the Blushing Propensity scale while singing and reading aloud, and while listening to audiotapes of their performance. After each task half of the participants were told that they had blushed, and the rest were told that they had not blushed. Blood flow increased progressively in participants with high blushing propensity scores who were given "blushing" feedback, but not in the other participants. This finding suggests that expecting to blush may become a self-fulfilling prophecy. Verbal feedback about blushing strongly influenced subsequent social discomfort, and mimicked the effects of blushing propensity on ratings of embarrassment and blushing intensity. In sum, the findings support the view that preconceptions about blushing propensity are shaped by past learning experiences, that concern about blushing is a major source of discomfort in embarrassing situations, and that these concerns are often unrelated to the actual intensity of blushing.     

An investigation of relationships between teachers' ratings of behavior and children's personality traits

This study examined the relationships between teachers' ratings of children's behavior on the Behavior Problem Checklist and children's selfreported personality source traits on ageappropriate Personality Questionnaires. The sample consisted of 254 children from first through eighth grades and 13 teachers in a rural Maine elementary school. Analysis of the data revealed that teachers' ratings and children's self-reports in grades four through six agreed more frequently about problematic behavior than did children's self-reports and teachers self-ratings in grades one through three and seven and eight. In general, the study (1) supported the validity of teacher judgments made with the Behavior Problem Checklist, (2) demonstrated the ckitical need for more than one perspective when identifying and defining maladaptive behaviors potentially indicative of emotional disturbance, and (3) suggested the need to increase the accuracy of teachers' perceptions and evaluations of children's behavior.     

Effects of methylphenidate alone and in combination with behavior modification procedures on the behavior and academic performance of hyperactive children

Twenty hyperactive 6- to 9-year-old children of normal intelligence were studied in a half-day laboratory classroom in a 2-week period baseline-treatment-reversal design for behavior modification. Under double-blind conditions half the children were placed on .3 mg/kg of Ritalin and half on placebo for the entire program. The classroom program consisted of a group period with immediate reinforcement possible, and an individual time period without immediate reinforcement possible. Behavior modification caused a significant decrease in nonattending, out-of-seat, inappropriate vocalizing and inappropriate peer interaction behavior in the group period. Fidgeting, a nontargeted behavior, was not significantly decreased during this period but did signficantly decrease as a result of medication. No other drug effects occurred during this period. During the individual period, the results were essentially reversed. There were no significant behavior modification effects observed. Significant reductions resulted from medication in all behaviors except out-of-seat and fidgeting. Behavior modification alone significantly affected the two academic measures. No significant effects were seen on the Conners Abbreviated Teacher Rating Scale. No significant interactions were noted between medication and behavior modification.This study was supported by a grant from the Health Services and Mental Health Administration, Maternal and Child Health Service Project 920.

Spatial knowledge of geographical globes: Evidence of vertical alignment effects

This study investigated human spatial memory of geographical globes. In two experiments, participants studied locations presented on a three‐dimensional globe. Subsequently, participants' knowledge of the locations was tested employing two types of pointing task. Directional judgments from imagined locations on the globe were performed either vertically through the ground (as if digging a straight tunnel between the locations) or horizontally along the surface of the globe (the shortest distance for an aircraft to fly to a given destination). In the vertical pointing task, judgments originating from imagined locations in the upper hemisphere were superior by comparison with those originating from imagined locations in the lower hemisphere. Performance in the horizontal pointing task was more variable, with a tendency for superior judgments originating from imagined locations in the lower hemisphere. The results provide evidence of a novel alignment effect involving vertical judgments.
