An experiment is reported in which the effect of sex composition on the creativity of brainstorming groups is investigated. It was hypothesized that mixed sex groups would be more creative than either homogeneous male or homogeneous female groups. Fifteen groups, consisting of four members each two males and two females; four females; four males, took part in the experiment. The experimenter noted the number of ideas generated per person, as well as the different associations with these ideas, and the number of different angles from which the task was approached. After finishing the exercise, subjects completed a post-experimental questionnaire. Results show that heterogeneous groups produced more creative outcomes than homogeneous groups. Also, they rated their process more positively. These findings are discussed in relation to the type of task used, and in relation to the general notion that heterogeneous groups are likely to produce more creative outcomes yet suffer from more process problems as compared to homogeneous groups.  相似文献

Analysis of cross-sectional data from the normative sample of the Wechsler Memory Scale - Third Edition (WMS-III) revealed different patterns of age-related differences in memory span measures depending on the type of memory item, processing demands, and the age of the older adult group. Regression of memory span on age revealed that the slope for Spatial Span raw scores was significantly more negative than the slope for Digit Span raw scores. There was no significant difference, however, either between the slopes for forward and backward Digit Span or between the slopes for forward and backward Spatial Span. Regression of Letter-Number Sequencing raw scores on age showed a distinctive, curvilinear pattern. Taken together, the present findings suggest that at least two mechanisms are involved in age-related differences in memory span. One mechanism, associated with a relatively linear decrease in memory span as a function of age, may differentially affect the storage of different types of information (e.g., sequences of digits vs. spatial locations). The other mechanism, evidenced by the curvilinear trend in Letter-Number Sequencing scores, may be tentatively attributed to a decline in executive aspects of working memory that becomes increasingly pronounced with age.  相似文献

This article describes the value of life design counselling with an abandoned adolescent female. The participant was selected purposively from among a group of abandoned adolescent females who had expressed a need for career counselling. The life intervention comprised two 90-minute sessions per week over a period of a month. Life design data included collage, family constellation, life line, career style interview, asset map and life chapters. Following the intervention, the participant demonstrated career adaptability and an eagerness to take an active part in her evolving life story. Life design counselling has potential to meet the career counselling needs of children with neglect and abandonment experience.  相似文献

Working with the body in Mindfulness-Based Cognitive Therapy (MBCT) is often seen as a ‘means to an end’; that is, a vehicle for diverting attention from negative thought patterns, thereby fostering a detached metacognitive awareness of problematic thinking. The MBCT literature, however, accords the body a more central role. The literature expresses both the idea that the body is integral to a basic level of meaning creation experienced as a ‘bodily felt sense of something’ and that direct sensory or bodily awareness can contribute to a critical change in the felt sense of emotional difficulties. Tracing the development of the concept of the body in clinical cognitive theory, the paper concludes that these ideas of the body are anticipated in earlier revisions to Beck's schema theory. The paper concludes that research into the psychological mechanisms behind bodily awareness would be a fruitful supplement to the current research focus on metacognitive awareness.  相似文献

Toddlers' performance on a seriation sequencing task was measured after exposure to a video as a function of the social meaningfulness of the character. Forty eight 21-month-old toddlers were randomly assigned to a socially meaningful character video demonstration, a less socially meaningful character video demonstration, or a no exposure control group. Results indicated that toddlers learned the seriation sequencing task better from a video when a socially meaningful character, rather than a less socially meaningful character, demonstrated the task. Our findings demonstrate that toddlers under age two can learn cognitive, logical reasoning skills from a video presentation when the onscreen character is socially meaningful to them.  相似文献

This pilot study examined the feasibility, acceptability, and preliminary outcomes of a linguistically and culturally adapted intervention for immigrant Latina mothers with depression and their families. Fortalezas Familiares (Family Strengths) is a community‐based, 12‐week, multifamily group intervention that aims to increase communication about family processes leading up to and affected by the mother's depression, build child coping and efficacy, enhance parenting competence and skills, and promote cultural and social assets within the family. In terms of feasibility, of 16 families who enrolled and participated in the intervention, 13 families attended more than 90% of meetings and completed the intervention. Posttests reported positive changes following the intervention, including improved psychological functioning, increased family and marital support, and enhanced family functioning, as reported by mothers and other caregivers. Mothers also reported decreased conduct and hyperactivity problems among their children. Children reported positive changes in their psychological functioning and coping, parenting warmth and acceptance, and overall family functioning. Postintervention focus groups and surveys measuring acceptability revealed families' satisfaction with the intervention and suggested areas of improvement. We discuss similarities and differences in outcomes between the adapted intervention, Fortalezas Familiares, and the original intervention, Keeping Families Strong, and propose future areas of intervention adaptation and development.  相似文献

Swimming movements of 7 European green frogs (Rana esculenta) were studied, starting from the detailed analysis of the speed and timing of the propulsive, glide, and recovery phases of their intermittent swimming behavior. First, the authors identified the spatiotemporal factors used by the frogs to modulate their swimming behavior. None of the gait variables correlated strongly with average swimming speed, and no significant correlations were found between variables belonging to different phases. There did not seem to be an obvious control strategy. Instantaneous speeds at the transition of the different phases all increased significantly with average speed, however. The strong correlation between maximal speed at the end of propulsion and the speed averaged over a cycle might reflect the dominance of the propulsive phase in the determination of the overall swimming speed. The modulation of swimming speed thus seemed largely comparable with the regulation of jumping distance. That finding was confirmed in a mathematical model, in which the positive correlations between both glide and recovery speeds, on the one hand, and average speed, on the other, were shown to be only mathematical consequences of the strong impact of the propulsive phase on overall swimming performance. That finding suggests that the correlations did not result from an active control strategy.  相似文献

Game playing behavior of same and mixed sex pairs of 5-, 8-, and 11-year-old American children was compared, using a game in which cooperative behavior maximized reward. Pairs of 8- and 11-year-old children were relatively more cooperative and attained significantly more Joint Reward Goals than 5-year-old pairs. Older pairs were not maximally cooperative, however, in terms of all the dependent measures; in adjusting for initial differences on practice trials, 5-year-olds and 8-year-olds took less time than the 11-year-olds, and 11-year-old pairs of boys took significantly more time than all other pairs. In addition, cooperative behavior increased across trials, especially for the 11-year-old children.  相似文献

A number of correlational studies have established a clear association between perfectionism, control and beliefs regarding body shape in eating disorders (EDs). The aim of this study is to test the effectiveness of the above- mentioned associations in exploring the presence of intuitive heuristics. Intuitive heuristics can be conceived as as mental shortcuts, cognitive processes that are highly susceptible to irrational biases. Forty one non clinical female controls and 27 in-patient females with an ED diagnosis participated in an experimental task that tested whether participants would show an intuitive rather than a logically based link between perfectionism in different domains (study, work, hygiene) and a thin body shape. In the healthy female participants the occurrence of proposed link was noted in the hygiene domain only, while ED participants showed this intuitive association in all the domains explored: study, work, and hygiene. The study confirms in clinical ED sample a wider employment of heuristics associating perfectionism and thinness that is based on purely intuitive irrational reasoning.  相似文献

The goal of this study was to examine whether listeners bilingual in Spanish and English would have difficulty in the discrimination of English vowel contrasts. An additional goal was to estimate the correlation between their discrimination and production of these vowels. Participants (40 bilingual Spanish- and English-speaking and 40 native monolingual English-speaking college students, 23-36 years of age) participated (M age = 25.3 yr., Mdn = 25.0). The discrimination and production of English vowels in real and novel words by adult participants bilingual in Spanish and English were examined and their discrimination was compared with that of 40 native monolingual English-speaking participants. Stimuli were presented within triads in an ABX paradigm. Novel words were chosen to represent new words when learning a new language and to provide a more valid test of discrimination. Bilingual participants' productions of vowels were judged by two independent listeners to estimate the correlation between discrimination and production. Discrimination accuracy was significantly greater for native English-speaking participants than for bilingual participants for vowel contrasts and novel words. Significant errors also appeared in the bilingual participants' productions of certain vowels. Earlier age of acquisition, absence of communication problems, and greater percentage of time devoted to communication contributed to greater accuracy in discrimination and production.  相似文献
