We report an investigation of the development of visual expectancies in 3.5-month-old infants. One of the infant's eyes was videorecorded as the infant watched a series of slides that were presented noncontingent on behavior. Babies were presented an alternating and an irregular series of 30 slides with a 700-msec onset duration separated by an interstimulus interval (ISI). The ISI for the alternating series was 1,100 msec, whereas the slides for the irregular series were separated by 900, 1,100, or 1,300 msec, randomly ordered. One-half of the babies saw the irregular series first, and one-half saw the regular series first. Babies in both groups provided evidence that they developed expectations for the visual events in the alternating series. Their reaction times (RTs) declined significantly from 3-5 "baseline" presentations, and their RTs were reliably faster during the alternating than the irregular series. Additionally, babies in the alternating-late group had significantly more stimulus anticipations during the alternating than during the irregular series. These findings indicate that 3.5-month-olds can detect regularity in a spatiotemporal series, will develop expectancies for events in the series, and will act on the basis of those expectancies even when those actions have no effect on the stimulus events. We believe that infants are motivated to develop expectations for noncontrollable spatiotemporal events, because these expectations permit them to bring their visual behavior under partial internal control.

Child victims must cope not only with the emotional consequences of criminal acts but also with the potentially traumatizing effects of legal involvement. Dramatic increases in the reporting of child sexual abuse are bringing greater numbers of children into contact with the criminal justice system, raising fears that child victims of sex crimes will be further harmed by the courts. In the present study, the effects of criminal court testimony on child sexual assault victims were examined in a sample of 218 children. From this sample, the behavioral disturbance of a group of "testifiers" was compared to that of a matched control group of "nontestifiers" at three points following testimony: 3 months, 7 months, and after prosecution ended. At 7 months, testifiers evinced greater behavioral disturbance than nontestifiers, especially if the testifiers took the stand multiple times, were deprived of maternal support, and lacked corroboration of their claims. Once prosecution ended, adverse effects of testifying diminished. In courthouse interviews before and after testifying, the main fear expressed by children concerned having to face the defendant. Children who appeared more frightened of the defendant while testifying were less able to answer the prosecutors' questions; and later, after the cases were closed, they were more likely to say that testifying had affected them adversely. The two most pervasive predictors of children's experiences in the courtroom, however, were age and severity of abuse. Despite relevant laws, few innovative techniques were used to help the children testify. The results are discussed in relation to children's ability to cope with stressful situations, the interaction of the legal system with the child/family system, and debates about the need to protect child victims who testify in criminal court.

Evaluation of child sexual abuse often necessitates interviewing children about genital touch, yet little scientific research exists on how best to obtain children's reports of genital contact. To examine this issue, 72 five- and seven-year-old girls experienced a standardized medical checkup. For half of the children, the checkup included a vaginal and anal examination (genital condition); for the other half, the checkup included a scoliosis examination instead (nongenital condition). The children's memories were later solicited through free recall, anatomically detailed doll demonstration, and direct and misleading questions. The majority of children in the genital condition revealed vaginal and anal contact only when asked directly about it. Children in the nongenital condition never falsely reported genital touch in free recall or doll demonstration; when asked directly, the false report rate was low. Significant age differences in free recall and doll demonstration, found only in the nongenital condition, implicated socioemotional factors as suppressing the reports of older children who experienced genital contact.

Age differences in children's ability to recount a stressful event were explored, as were several ways to improve children's reports. Seventy 3- to 7 year olds were videotaped while receiving inoculations at a medical clinic. It was predicted that multiple interviews would maintain memory and strengthen resistance to sugges-tion. It was also predicted that social support would ease intimidation and thus lessen children's suggestibility. To test these predictions, children were inter-viewed either once after a 4-week delay or twice, following 2- and 4-week delays, and under either "reinforcing" or "nonreinforcing" conditions. Age differences in answers to specific and misleading questions and in performance on a photo identification task were prevalent. However, multiple interviews and reinforce-ment supported more accurate reports. Training was effective in reducing false identifications on the photo identification task, especially for older children. Children's accuracy was unrelated to parental ratings of the stressfulness of the event. Our findings have implications for the testimony of child victim witnesses and for child-adult reconstruction of a child's past history.(Psychology)

Children's testimony often plays a central role in prosecutions of child sexual abuse. Nevertheless, research on jurors' perceptions of the credibility of child sexual assault victims remains limited. In three experiments, we examined mock jurors' reactions to children's testimony about sexual abuse. Participant jurors were exposed to videotaped or written scenarios of child sexual abuse trials and then rated victim credibility and defendant guilt. Analyses indicated that: (a) victim age was either inversely related or unrelated to perceptions of victim credibility, (b) women were more likely than men to find child victims credible, (c) corroborating testimony from a child victim increased the credibility of another child victim, and (d) exposure of participants to past criminal acts and other negative defendant character evidence heightened perceived victim credibility and defendant guilt. Implications for understanding jurors' reactions to child witnesses are discussed.

Inherent in false confessions is a person taking responsibility for an act he or she did not commit. The risk of taking such responsibility may be elevated in juveniles. To study possible factors that influence individuals' likelihood for taking responsibility for something they did not do, participants in a laboratory experiment were led to believe they crashed a computer when in fact they had not. Participants from 3 age groups were tested: 12-and 13-year-olds, 15-and 16-year-olds, and young adults. Half of the participants in each age group were presented with false evidence indicating liability. Additionally, suggestibility was investigated as a potential individual-difference factor affecting vulnerability to admissions of guilt. Results showed that younger and more suggestible participants were more likely than older and less suggestible participants to falsely take responsibility. Implications of these findings for juvenile justice are discussed.
