Cognitive Response Repertoires to Child Noncompliance by Mothers of Aggressive Boys

Cognitive response repertoires to videotaped child noncompliance episodes were examined in mothers of aggressive (MAs) and nonaggressive 4–6-year-old boys. Mothers provided open-ended solutions to three subtypes of child noncompliance under conditions of time pressure, or after they waited for 15 s to consider alternatives. Solutions were coded as assistance/facilitation, coercion, deference, or explanation/clarification. Compared with controls, MAs offered fewer explanation/clarification responses, more coercive responses, and fewer unique solutions during pressured responding. Two to 6 weeks later, mothers were videotaped while participating with their sons in a challenging block-building task. Maternal responses to the vignettes predicted conflict escalation during block building, even after rates of concurrent and past child noncompliance were partialled out. Implications for parent-training models are considered.     

Conceptual and perceptual processes in prospective remembering: differential influence of attentional resources

Does prospective remembering rely on strategic, attentionally demanding processes? We report three experiments suggesting that the extent to which attentional processes are required varies according to the character of ongoing task processing. Study-test changes in the semantic context of targets had a negative effect on prospective memory performance when participants were engaged in a conceptually focused (sentence verification) task (Experiment 1). Similarly, prospective remembering was lower following study-test changes in perceptual format (font) in the context of a perceptually focused (readability rating) ongoing task (Experiment 2). However, although dividing attention at retrieval had a negative effect during the performance of an ongoing conceptual task (Experiments 1 and 3), it had no effect during an ongoing perceptual task (Experiments 2 and 3). Thus, both perceptual and conceptual process are implicated in prospective remembering, but the processing focus of the task in which remembering should occur may mediate the requirement for strategic processes. These findings suggest that more than one retrieval route is available for prospective remembering and that selection of the route depends on the nature of the task and the processing that occurs at encoding and retrieval.     

Asymmetric aging effects on semantic and phonological processes: naming in the picture-word interference task

In 2 experiments, participants named pictures while ignoring auditory word distractors. For pictures with homophone names (e.g., ball), distractors semantically related to the nondepicted meaning (e.g., prom) facilitated naming by top-down phonological connections for young but not for older adults. Slowing from unrelated distractors and facilitation from phonologically related distractors were age invariant except in distractors that were both semantically and phonologically related. Only distractors semantically related to the picture interfered more for older than younger adults. These results ar einconsistent with age-linked deficits in inhibition of irrelevant information from either internal or external sources. Rather, aging affects priming transmission in a connectionist network with asymmetric effects on semantic and phonological connections involved in comprehension and production, respectively.     

Schizophrenia risk and paternal age: a potential role for de novo mutations in schizophrenia vulnerability genes

How schizophrenia (SZ) is maintained at roughly 1% of the population despite diminished reproduction is one puzzle currently facing researchers. De novo mutations were first proposed over half a century ago as a source for new SZ genes. Current evidence linking advancing paternal age to SZ risk makes revisiting this hypothesis important. Advancing paternal age is the major source of new mutations in the human population. This article will examine potential mechanisms whereby parental age may impact new mutations, as well as review recent data supporting such a hypothesis.     

MR imaging of fetal central nervous system abnormalities

Ultrasound is the screening modality of choice for fetal imaging. However, when additional information regarding fetal anatomy or pathology is needed, fast MR imaging is increasingly being used as a correlative imaging modality. Performances of high quality sonographic and MR examinations as well as interpretation by individuals familiar with prenatal diagnosis are important factors for optimal parental counseling. MR imaging frequently adds additional information regarding fetal central nervous system anomalies beyond that available with ultrasound. This information commonly changes patient counseling, and at times patient management.     

Predicting handwriting performance of early elementary students with the developmental test of visual-motor integration

The purpose of this study was to examine use of the Developmental Test of Visual-Motor Integration in predicting handwriting performance of early elementary students and the contribution of sex. An additional purpose was to examine whether successful completion of the first nine figures or the oblique cross from the test predicted handwriting. 101 children were tested at the beginning of their kindergarten year and again in the middle of the first-grade year on the Scale of Children's Readiness In PrinTing (SCRIPT). The VMI kindergarten scores did not significantly predict first-grade SCRIPT scores for the sample as a whole. When boys and girls were considered separately. VMI scores predicted handwriting SCRIPT scores for girls, but accounted for only 10% of the variance. Successful performance on the first nine VMI figures was significantly associated with handwriting for girls but not boys, while the oblique cross did not significantly predict handwriting performance. These results do not provide clear support for administration of the Developmental Test of Visual-Motor Integration during kindergarten as a tool to identify children at risk for handwriting difficulties.     

Research ethics for mental health science involving ethnic minority children and youths

In response to U.S. Public Health Service projects promoting attention to disparities in the outcomes of mental health treatments, in July 2001, the American Psychological Association, the National Institute of Mental Health, and the Fordham University Center for Ethics Education convened a group of national leaders in bioethics, multicultural research, and ethnic minority mental health to produce a living document to guide ethical decision making for mental health research involving ethnic minority children and youths. This report summarizes the key recommendations distilled from these discussions.     

The pleasures of uncertainty: prolonging positive moods in ways people do not anticipate

The authors hypothesized that uncertainty following a positive event prolongs the pleasure it causes and that people are generally unaware of this effect of uncertainty. In 3 experimental settings, people experienced a positive event (e.g., received an unexpected gift of a dollar coin attached to an index card) under conditions of certainty or uncertainty (e.g., it was easy or difficult to make sense of the text on the card). As predicted, people's positive moods lasted longer in the uncertain conditions. The results were consistent with a pleasure paradox, whereby the cognitive processes used to make sense of positive events reduce the pleasure people obtain from them. Forecasters seemed unaware of this paradox; they overwhelmingly preferred to be in the certain conditions and tended to predict that they would be in better moods in these conditions.     

Testing for localized stimulus enhancement and object movement reenactment in pig-tailed macaques (Macaca nemestrina) and young children (Homo sapiens)

Four puzzle boxes were used to investigate localized stimulus enhancement and object movement reenactment (OMR) in 13 pig-tailed macaques (Macaca nemestrina) and 30 human infants (Homo sapiens). Participants received contrasting demonstrations on each box. A circular lid was gripped by its rim or handle and swiveled to the left or right. A flap door was pushed or flipped. A sliding lid was pushed to the left or right. A pin bolt was demonstrated being pushed down, or the participants were left to solve the puzzle for themselves. Despite the fact that the monkeys watched the demonstrations about 60% of the time, only a weak OMR effect was found on the sliding lid. In contrast, the children watched significantly more, and there was clear evidence of socially mediated learning on all of the boxes.
