Recent studies have shown associations between maternal psychopathology and inhibited behaviors in infants. Moreover, physiological factors have been identified as affecting the continuity of behavioral inhibition across childhood. The purpose of the present study was to examine electroencephalogram (EEG) activity and inhibited behavior in 12-month-old infants of depressed versus non-depressed and mothers. Repeated measures MANOVAs indicated that the infants of mothers with stable psychopathology had greater relative right frontal EEG asymmetry, a pattern that typically accompanies greater negative affect and greater withdrawal behaviors. Infants of affectively ill mothers also showed more proximal behaviors toward a stranger and a novel toy than infants of well mothers, but fewer non-proximal behaviors toward their mothers. These results are discussed within a framework of behavioral inhibition for infants exposed to early psychopathologies in their mothers. 相似文献

The aim of this investigation was to examine the time course and the relative contributions of perceptual and post-perceptual processes to categorical perception (CP) of color. A visual oddball task was used with standard and deviant stimuli from same (within-category) or different (between-category) categories, with chromatic separations for within- and between-category stimuli equated in Munsell Hue. CP was found on a behavioral version of the task, with faster RTs and greater accuracy for between- compared to within-category stimuli. On a neurophysiological version of the task, event-related potentials (ERPs) showed earlier latencies for P1 and N1 components at posterior locations to between- relative to within-category deviants, providing novel evidence for early perceptual processes on color CP. Enhanced P2 and P3 waves were also found for between- compared to within-category stimuli, indicating a role for later post-perceptual processes. 相似文献

Performance Indicators in Math: Implications for Brief Experimental Analysis of Academic Performance
Brief experimental analysis (BEA) can be used to specify intervention characteristics that produce positive learning gains
for individual students. A key challenge to the use of BEA for intervention planning is the identification of performance
indicators (including topography of the skill, measurement characteristics, and decision criteria) that meaningfully relate
to longer term success in the learning environment. This study investigates the utility of various curriculum-based assessment
and measurement estimates of mathematics performance for predicting functional outcomes (i.e., retention of learned skills
over time and faster learning of related content in the future). All children in grades 2–5 at the participating school participated
in protocol-based computational fluency-building intervention 4 days per week for an entire school year. Specific criteria
were applied each week to systematically increase intervention difficulty classwide according to a pre-established sequence
of computational skill objectives. Three measurements were routinely obtained. Each week children completed a timed probe
of the skill for which intervention was currently occurring and a timed probe of previously mastered skills from the sequence
of computational skill objectives. Each month, all children completed a timed probe of mathematics skills representing computational
skills that students were expected to master by year’s end at each grade level. At all grade levels, learning a skill that
appeared early in the hierarchy or sequence of skills related positively to learning of future related and more complex computational
skills. Fluency criteria were specified that predicted retention of the skill over several months. 相似文献

The consequences of the early onset of substance use on later outcomes are a public health concern. In the present study,
we examined neighborhood risk factors as a possible predictor of the onset of substance use in adolescents. In addition, we
assessed the potential buffering effects of parental supervision on the relationship between neighborhood risk and the onset
of substance use. The participants included 95, abstinent, African American 6th graders (mean age = 11.5 years) who enrolled
in one site of a national, multi-site study of high-risk youth participating in a federally sponsored program. In the 6th
and 8th grades, the participants completed self-report measures regarding substance use, perceived negative neighborhood activities
and parental supervision. Logistic regression analyses demonstrated that both exposure to negative neighborhood activities
and low parental supervision increase the onset of substance use by the 8th grade among African American adolescents. However,
the results suggested that parents can protect their adolescents from the impact of exposure to adverse neighborhood factors
by providing appropriate supervision. 相似文献

We evaluated the efficacy of a social skills training intervention designed to improve adolescents’ social, emotional and
behavioral adjustment, Social Skills Group Intervention-Adolescent (S.S.GRIN-A). Seventy-four adolescents (ages 13–16 years)
and their parents were randomly assigned to either the treatment group (N = 40) or a wait-list control group (N = 34). Adolescents in the treatment and control groups were compared on global self-concept, social self-efficacy, internalizing
problems, and externalizing problems pre- and post-intervention. Youth in the treatment group demonstrated enhanced global
self-concept, increased social self-efficacy, and decreased internalizing problems as compared to youth in the control group.
No differences in externalizing behavior were found. We discuss the effectiveness of S.S.GRIN-A as a general program designed
for addressing a range of adjustment issues and social skill deficits in adolescents. 相似文献

In six experiments with English‐learning infants, we examined the effects of variability in voice and foreign accent on word recognition. We found that 9‐month‐old infants successfully recognized words when two native English talkers with dissimilar voices produced test and familiarization items ( Experiment 1 ). When the domain of variability was shifted to include variability in voice as well as in accent, 13‐, but not 9‐month‐olds, recognized a word produced across talkers when only one had a Spanish accent ( Experiments 2 and 3 ). Nine‐month‐olds accommodated some variability in accent by recognizing words when the same Spanish‐accented talker produced familiarization and test items ( Experiment 4 ). However, 13‐, but not 9‐month‐olds, could do so when test and familiarization items were produced by two distinct Spanish‐accented talkers ( Experiments 5 and 6 ). These findings suggest that, although monolingual 9‐month‐olds have abstract phonological representations, these representations may not be flexible enough to accommodate the modifications found in foreign‐accented speech. 相似文献

According to attachment theory, insecure individuals respond to events in their romantic relationships in ways that sometimes can be destructive. The objective of this research was to examine how these responses may accumulate over repeated interactions to influence the quality of the relationship. Across three studies, participants were presented with a "Choose Your Own Adventure" dating story in which they made choices based on their partners' behaviors. In each study we found that attachment styles predicted the kinds of choices participants made at the outset of and throughout the story. Additionally, relationship satisfaction was related to the choices participants made throughout the fictional narrative, even in situations in which the partner's behavior was the same for all participants. 相似文献

Medical psychology in Australia is heavily influenced by British and American thought. The dominant model for clinical training and practice is the scientist–practitioner model, yet a gulf exists between academic and practice settings. Membership of the professional society requires 6 years of university study in psychology. However, registration requires only 4 years training in psychology. Medical psychologists provide a broad range of services in hospital and community settings, often within multidisciplinary teams. Challenges for the future include bridging the divide between university and health settings, increasing qualifications required for registration, making psychology culturally relevant, and demonstrating to funding managers that psychological interventions are both clinically effective and cost effective. 相似文献

The present field study examined commuters’(N= 152) willingness to fund improvements in public transit. Consistent with Samuelson's (1993; Samuelson & Messick, 1995) multiattribute evaluation model of structural change in social dilemmas, support for the transit plan was higher when it was perceived to be (a) effective at reducing congestion and pollution, (b) personally beneficial, and (c) fair in terms of taxes and benefits. Also consistent with predictions, these relationships were moderated by individual differences in social value orientation (MClintock, 1968) and the consideration of future consequences (CFC; Strathman, Gleicher, Boninger, & Edwards, 1994). Prosocials responded more to the perceived fairness of the plan, while proselfs responded more to the plan's effectiveness in reducing congestion. Low CFCs responded more to the plan's personal benefits and effectiveness in reducing congestion, while high CFCs responded more to the plan's effectiveness in reducing pollution. 相似文献
