From beyond to within their grasp : The rudiments of analogical problem solving in 10- and 13-month-olds

Four experiments were conducted to assess infants ability to solve isomorphic problems and to explore the nature of early representations. Ten- and 13-month-olds attempted to solve problems that required combining 2 subgoals to bring a toy (goal object) within reach. A problem-series paradigm was used in which 3 tasks differing in surface features but sharing common goal structures and similar solutions were presented. The results indicate that 13-month-olds transferred a modeled solution strategy across isomorphic problems, whereas 10-month-olds did so only after experiencing either multiple source problems or high perceptual similarity between problems. Comprehension of the relations between solution actions and outcome, and between tools and target object, appeared critical to transfer. The results suggest that 1-year-olds can construct relatively abstract and flexible mental representations and that analogical problem solving may be 1 of the major accomplishments during the 1st year of life.

Comprehension of Televised Stories in Boys With Attention Deficit/Hyperactivity Disorder and Nonreferred Boys

Two studies compared comprehension of televised stories by 7- to 12-year-old boys with attention deficit/hyperactivity disorder (ADHD) and nonreferred comparison boys. Boys watched one show with toys present and one with toys absent. Visual attention was continuously recorded, and recall was tested after each show. Across studies, visual attention was high with toys absent but decreased sharply with toys present for boys with ADHD. Groups showed similar levels of cued recall of discrete units of information regardless of differences in attention. When recall tasks and television story structure required knowledge of relations among events, the reduced attention of boys with ADHD interfered with recall. Although visual attention of comparison boys also decreased to some extent with toys present, there was no such decrement in recall. Implications of the difficulties children with ADHD have in integrated story comprehension are discussed.

Difficulties in Comprehending Causal Relations Among Children With ADHD: The Role of Cognitive Engagement

The present study examined whether time spent in long looks (i.e., >or=15 s), an index of cognitive engagement, would account for differences between children with attention deficit hyperactivity disorder (ADHD) and comparison children in understanding causal relations. Children viewed two televised stories, once in the presence of toys and once in their absence. Dependent variables were visual attention and questions tapping factual information and causal relations. Comparison children answered significantly more causal relations questions than did the children with ADHD, but only in the toys-present condition. Four lines of evidence revealed that the difficulties children with ADHD had in answering causal relations questions in the toys-present condition could be linked specifically to this groups decreased time spent in long looks.

The believability of repressed memories

Two experiments investigated how mock jurors react to a case involving a repressed memory of child sexual assault. Subjects read a fictional civil trial (Experiment 1) or criminal trial (Experiment 2) summary involving the sexual assault of a 6-year-old female. The summary was presented in one of three conditions: (a)child condition: the alleged victim reported her memory of the assault in the same year that the assault occurred; (b)repressed condition: the alleged victim reported the assault 20 years later, after remembering it for the first time; or (c)no-repressed condition: the alleged victim reported the assault 20 years later, but the memory of the assault had been present for the 20 years. Although the testimony of the alleged victim was believed to some extent in all conditions, the alleged victim in the child condition was believed at the highest level, and this was associated with more decisions against the defendant. The results are discussed in terms of how delayed reporting of child sexual assault crimes is associated with lower believability of the alleged victim.

The impact of DNA evidence in a child sexual assault trial.

Two experiments investigated the impact of DNA evidence in a child sexual assault (CSA) case involving a 6-year-old alleged victim. In Experiment 1, participants read criminal trial summaries of CSA cases in which only DNA evidence was presented, only the alleged child victims testimony was presented, or both forms of evidence were presented. When DNA evidence was presented, there were more guilty verdicts and greater belief of the alleged victim than when only the alleged victim testified. In Experiment 2, DNA evidence was countered by an alibi witness testifying as to the defendants whereabouts at the time of the alleged assault. The alibi witness reduced the influence of DNA evidence compared with when DNA evidence was presented without this witness. These results are discussed in terms of the comparative strengths of DNA evidence versus the testimony of the alleged victim.

Predictors of Job Satisfaction Among Active Duty and Reserve/Guard Personnel in the U.S. Military

In this study, we examined psychological, demographic, and physical predictors of job satisfaction among military personnel across the Armed Forces. Data were collected from 24,881 members of the Active Duty and Reserve/Guard components. Overall, military job satisfaction was higher among Reserve/Guard personnel than among those on Active Duty. Separate regression models for the 2 components revealed generally similar predictors of job satisfaction. The 2 strongest predictors were the perception of a relatively high level of job pressure experienced by military personnel and the belief that the biggest problem in ones life was the result of job-related issues (such as a supervisor) rather than nonjob issues (such as health or family). Findings suggest areas in which the military can intervene to increase the satisfaction of personnel and presumably their likelihood of remaining in the military. Because considerable job pressure may be inherent in the nature of the military mission, attention should be given to ensuring that personnel learn and use effective coping skills to manage stressors.

Story Comprehension in Children with ADHD

A wealth of research is available examining childrens story comprehension. However, little attention has been directed toward understanding the story comprehension of children with attention deficit hyperactivity disorder (ADHD). The present paper attempts to integrate the developmental literature on childrens story comprehension with the little that is known about the story comprehension processes of children with ADHD. This review is guided by a network model of story representation that emphasizes the structure of causal and enabling relations between story events. Examination of the available studies indicates that children with ADHD lag behind their peers in their understanding of causal relations, and that their attentional problems may contribute to difficulties in understanding factual information in the preschool years and causally related information in the elementary years. Some evidence also is presented suggesting that children with ADHD are less effective in taking advantage of story structure features in guiding their recall of story events. Suggestions for future research are offered that would elaborate our knowledge of the developmental progression in the processing of complex information by children with ADHD.

The Believability of Hearsay Testimony in a Child Sexual Assault Trial

Two experiments investigated how mock jurors react to hearsay testimony in a case involving child sexual assault. Participants read a fictional criminal trial summary involving the sexual assault of a 4-(Experiment 2 only), 6-, or 14-year-old female. The summaries were presented in one of four conditions: (a) child condition—the alleged victim testified; (b) hearsay condition—the alleged victim did not testify, but an adult hearsay witness did testify; (c) multiple condition (Experiment 1 only)—both the alleged victim and the adult hearsay witness testified; and (d) no-witness condition—neither the alleged victim nor the hearsay witness testified. The hearsay testimony was believed to a considerable degree, and this testimony led to an increase in the perceived guilt of the defendant. Moreover, these results were comparable to those of conditions in which the alleged victim testified. The results are discussed in terms of the psychosocial factors affecting the perception of hearsay testimony in a child sexual assault trial.

Brief Research Report: Age Factors Affecting the Believability of Repressed Memories of Child Sexual Assault

Two experiments investigated how mock jurors react to testimony involving claims of a repressed memory in a case involving child sexual assault. Participants read a fictional civil trial summary presented in one of three conditions: (a) immediate condition—the alleged victim testified immediately after the incident; (b) repressed condition—the alleged victim reported the assault 1–39 years later, after remembering it for the first time; or (c) not-repressed condition—the alleged victim reported the assault 1–39 years later, but the memory of the assault had been present for those years. When there was any type of delayed reporting, either the age of the alleged victim at the time of the assault was constant and her age at reporting varied (Experiment 1) or the age of the alleged victim at the time of the assault varied and her age at reporting remained constant (Experiment 2). The results showed that (1) a delay in reporting an incident adversely affected believability of the alleged victim and led to fewer rulings in support of the plaintiff compared to reporting it immediately, (2) longer delays in reporting generally led to lower alleged victim believability and fewer decisions in support of the plaintiff than shorter delays, (3) the age of the alleged victim at the time of the incident was a critical variable in determining belief of the alleged victim, and (4) men generally rated believability of the alleged victim lower and ruled in favor of the plaintiff less often than women. The results are discussed in terms of the psychosocial factors affecting the perception of delayed reporting in a child sexual assault trial.
