This research project was designed to investigate the possibility that asking subjects to respond in a mature manner when they take the Washington University Sentence Completion Test of Ego Development (WUSCTED) would result in higher test scores and improve the test-retest reliability of the measure. The results showed that there was a significant increase in Total Protocol Ratings (TPRs) and item sums in the experimental group (n = 32) over the control group (n = 32). In addition, the experimental group spent more time and used significantly more words in its response than did the control group. The question of improved test-retest reliability remains only tentatively resolved. The item sum scores showed a significantly higher correlation for the experimental instruction than for the control, although the test-retest agreement between TPR levels was insignificantly different in the two instructional groups. 相似文献

Recent research (e.g., Siegler, 1996) has discovered the important and vital role that variability plays among strategy use and development over time. However, as many researchers have pointed out (e.g., Miller, 1993), the majority of the research addressing this issue has focused on the outcomes, rather than on the potentially more informative aspects of variability, strategy development, and the process of adaptation. In this study, we examined the role of variability during strategy development, utilizing a longitudinal method. Thirteen participants were studied over 3 months as they coached a simulated football team. The results suggest that variability plays a major role in adaptive skill acquisition in a dynamic environment--in the direction, however, opposite to that predicted by previous research done with simple static tasks. 相似文献

Previous research has suggested that preschoolers possess a cognitive system that allows them to construct an abstract, coherent representation of causal relations among events. Such a system lets children reason retrospectively when they observe ambiguous data in a rational manner (e.g., D. M. Sobel, J. B. Tenenbaum, & A. Gopnik, 2004). However, there is little evidence that demonstrates whether younger children possess similar inferential abilities. In Experiment 1, the authors extended previous findings with older children to examine 19- and 24-month-olds' causal inferences. Twenty-four-month-olds' inferences were similar to those of preschoolers, but younger children lacked the ability to make retrospective causal inferences, perhaps because of performance limitations. In Experiment 2, the authors designed an eye-tracking paradigm to test younger participants that eliminated various manual search demands. Eight-month-olds' anticipatory eye movements, in response to retrospective data, revealed inferences similar to those of 24-month-olds in Experiment 1 and preschoolers in previous research. These data are discussed in terms of associative reasoning and causal inference. 相似文献

Neurocognitive function in monozygotic twins discordant for combat exposure: relationship to posttraumatic stress disorder 总被引:1,自引:0,他引:1

Neuropsychological deficits have been reported among trauma survivors with posttraumatic stress disorder (PTSD). It is often assumed that these cognitive difficulties are toxic consequences of trauma exposure. Alternatively, they may reflect preexisting characteristics that contribute to the likelihood of developing PTSD. To address this possibility, the authors evaluated cognitive performance in monozygotic twin pairs who were discordant for combat exposure. Pairs were grouped according to whether the combat-exposed brother developed PTSD. The combat-unexposed cotwins of combat veterans with PTSD largely displayed the same performance as their brothers, which was significantly lower than that of non-PTSD combat veterans and their brothers. The results support the notion that specific domains of cognitive function may serve as premorbid risk or protective factors in PTSD. 相似文献

Not quite as grown-up as we like to think: parallels between cognition in childhood and adulthood 总被引:1,自引:0,他引:1
Greater continuity in cognition between children and adults may exist than is usually appreciated. It was thought that after 3 to 4 years of age, the problem in switching on the dimensional-change card-sort task disappears. We show here, however, that if speed is used as the dependent measure, the effect of the first dimension is evident even in adults. Adults, like preschoolers, show difficulty in switching from a block of sorting by color or shape to a block of sorting by the other dimension. Notably, performance throughout the session was affected by the first dimension by which stimuli were sorted. We hypothesize that perhaps adults never fully outgrow any of the cognitive and perceptual biases of infancy and early childhood. Other examples of such biases that appear to still be present in adults are discussed. Conversely, the assumption that the optimal dependent measure for adults is the most sensitive measure for children is questioned. 相似文献

Speech perception is an ecologically important example of the highly context-dependent nature of perception; adjacent speech, and even nonspeech, sounds influence how listeners categorize speech. Some theories emphasize linguistic or articulation-based processes in speech-elicited context effects and peripheral (cochlear) auditory perceptual interactions in non-speech-elicited context effects. The present studies challenge this division. Results of three experiments indicate that acoustic histories composed of sine-wave tones drawn from spectral distributions with different mean frequencies robustly affect speech categorization. These context effects were observed even when the acoustic context temporally adjacent to the speech stimulus was held constant and when more than a second of silence or multiple intervening sounds separated the nonlinguistic acoustic context and speech targets. These experiments indicate that speech categorization is sensitive to statistical distributions of spectral information, even if the distributions are composed of nonlinguistic elements. Acoustic context need be neither linguistic nor local to influence speech perception. 相似文献

Since it appears that a wide divergence of opinion has existed between ministers and counselors in regard to such issues as a basic doctrine of man and the concept of permissiveness in interpersonal relationships, an attempt was made to compare seminary students and counselor trainees on their perceptions of human nature and tendencies toward authoritarianism. 相似文献

Posttraumatic stress symptoms are prominent in the lives of parents of young children with substance use disorders (SUD). Parenting experiences, particularly stress and competence, impact parenting behaviors and concomitant child growth and development. Factors that promote positive experiences of parenting, such as parental reflective functioning (PRF), and protect the mother and child from negative outcomes are crucial to understand to develop effective therapeutic interventions. The current US study analyzed baseline data from a parenting intervention evaluation to examine how length of substance misuse, PRF, and trauma symptoms were associated with parenting stress and parenting sense of competence among mothers in treatment for SUDs. Measures included the Addiction Severity Index, PTSD Symptom Scale-Self Report, Parental Reflective Functioning Questionnaire, Parenting Stress Index/Short Form, and Parenting Sense of Competence Scale. The sample included 54 predominantly White mothers with SUDs who had young children. Two multivariate regression analyses found that (1) lower parental reflective functioning and higher posttraumatic stress symptoms were associated with higher parenting stress, and (2) only higher posttraumatic stress symptoms were associated with lower levels of parenting sense of competence. Findings underscore the importance of addressing trauma symptoms and PRF when aiming to improve parenting experiences for women with an SUD. 相似文献
