Cigar and pipe smoking in the U.S. military: prevalence, trends, and correlates.

This article examines the prevalence, trends, and correlates in cigar/pipe smoking and their relation to cigarette smoking among active duty U.S. military personnel. An examination of the trends in cigar/pipe smoking was conducted with data from 1985 to 1998, and predictors of smoking were determined for 1998. Rates of cigar/pipe smoking declined from 1985 until about 1992 and then began to increase. From 1995 to 1998, there was a 75% increase in the prevalence of cigar/pipe smoking. Greater prevalence of cigar/pipe smoking was associated with male gender, younger age, relatively favorable beliefs and values toward smoking, and being a current cigarette smoker. Findings indicate a notable increase in past-year cigar/pipe smoking. These findings suggest that military tobacco prevention and early intervention programs would benefit from including components that deal specifically with cigar and pipe use in addition to cigarette smoking.

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 victim's 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 defendant's 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.

The relation of story structure properties to recall of television stories in young children with attention-deficit hyperactivity disorder and nonreferred peers.

In this study, the authors examined memory for televised stories to gain insight into similarities and differences in story comprehension between young children with attention-deficit hyperactivity disorder (ADHD) and their typical peers. In particular, the authors investigated the extent to which 4- to 6-year-old children's free recall of story events is predicted by several structural properties of story events (number of causal connections, whether an event is on or off the story's causal chain, story-grammar category, and position in the story's hierarchical structure), whether differences exist between children with ADHD and nonreferred comparison children in their sensitivity to structural features of stories, and whether age differences in sensitivity to structural features are similar for both groups. For both groups, recall of story events was predicted by all four structural properties, but the effects of the two causal properties was stronger for comparison children than for children with ADHD. Further examination revealed that this difference was observed only when a competing activity was available during television viewing. These findings indicate that both groups of preschool children are able to benefit from causal structure when recalling television stories, but that children with ADHD lose this benefit when attention is divided. Consistent with previous findings for nonreferred children (P. W. van den Broek, E. P. Lorch, & R. Thurlow, 1996), in both diagnostic groups the effects of causal properties increased across age, and older children were more likely to include causally important protagonists' goals in their recalls than younger children.

Comprehension of televised stories by preschool children with ADHD.

Investigated visual attention to and story comprehension of televised stories in 4- to 6-year-old children with attention deficit hyperactivity disorder (ADHD) and comparison children. Half of the children in each group watched the program with toys in the room, and the other half watched without toys. Visual attention to the television was recorded, and story comprehension was assessed by performance on cued recall questions. All children attended significantly less when toys were present, but the difference when toys were present was greater for children with ADHD. The groups did not differ on recall of factual information when toys were absent. When toys were present, the comparison children showed no decrement in performance on factual questions, whereas the performance of children with ADHD was significantly worse. On questions testing causal connections, the children with ADHD performed more poorly than comparison children regardless of whether toys were present. Implications of these results for understanding and treating the academic and social difficulties of children with ADHD are discussed.

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.

The effect of multiple childhood sexual assaults on mock-jurors' perceptions of repressed memories.

The effect of multiple childhood sexual assaults on the believability of a repressed memory of the assault was assessed using mock jurors. Participants read a fictional civil trial summary about a child sexual assault case presented in one of three reporting conditions: (a) immediate condition-the alleged victim testified immediately after the assault(s); (b) repressed condition-the alleged victim reported the assault(s) 20 years later, after remembering it/them for the first time; or (c) no-repressed condition-the alleged victim reported the assault(s) 20 years later, but the memory of the assault(s) had been present for those years. The number of assaults was either one or 30. The results showed that for all reporting conditions 30 alleged assaults led to relatively more decisions for the plaintiff than the defendant, and greater believability of the plaintiff. The increases in decisions rendered and believability were also generally true for the immediate condition compared to when there was a delay in reporting. The results are discussed in terms of mock jurors' perceptions of child sexual assault, both those reported immediately and those reported after many years.

Story comprehension in children with ADHD.

A wealth of research is available examining children's 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 children's 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.

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.

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 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.
