This investigation evaluated the degree to which creativity training, idea generation instruction, and creative process impacted idea production, creativeness of solutions, and leadership effectiveness. Three sets of hypotheses were tested with a 114 groups of adults. First, groups whose members had some (i.e., one CPS course) or advanced training (i.e., graduate-level study in creativity or creativity professionals) were significantly more effective at idea generation than groups without training. Furthermore, leaders with some and advanced training were perceived to be significantly more effective than those with no creativity training. With respect to creativeness of solutions, the advanced training groups outperformed all others. The second set of hypotheses focused on the effectiveness of idea generation instruction (i.e., instructions without brainstorming, brainstorming, and brainstorming with criticism). Analysis revealed no significant difference for idea generation instruction relative to idea production or creativeness of solutions. The final set of hypotheses examined the use of a simple process structure for groups without prior creativity training (i.e., distinct phases for idea generation and solution development). Analysis revealed that those meetings that followed a simple process structure out performed groups that did not follow a process for both idea generation and creativeness of solutions. Further results are presented and implications discussed.  相似文献

Some words have fewer direct associates than others, and, when words varying in set size are studied in a list-learning task, those with smaller sets are more likely to be recalled. This set-size effect is found in cued recall when the words are studied in the absence of related words, but not when studied in the presence of related words. Related words provide context and theoretically inhibit irrelevant associates. The present research determined that set-size effects are found when words are encoded in sentence contexts. In contrast to list-learning experiments, the results of three experiments found such effects even when lexically related words were present in the sentences. Other findings indicated that target-set-size effects were determined by the proximity of related words in the sentence and the nature of the test cue. The results are discussed in relation to a model for explaining set-size effects and to selective findings from the sentence-comprehension literature.  相似文献

Civic actions are behaviours intended to improve conditions for others or help shape a community's future. Such actions vary widely from voting to voluntary helping, from canvassing to community organizing, and attempts have been made to categorize the array of civic actions. However, the question of why young adults engage in some types of civic actions versus others is not well understood. Using data from 598 White, cisgender, heterosexual young adults in the United States, we examined the relations between individual civic efficacy, collective civic efficacy, and seven actions: writing social media posts, voting, buycotting, volunteering, participating in an organization, supporting political candidates, and protesting. We hypothesized that individual efficacy would be positively related to all seven actions, but collective efficacy would be more strongly related to collective or political actions, compared to the individual or civil ones. Logistic regression analyses showed that individual efficacy positively predicted engagement in all seven civic actions. Individual and collective efficacy had a complex curvilinear relation with buycotting and supporting political candidates. Implications for future research and applications aimed at promoting civic engagement amongst young adults are discussed.

Operant temporal discrimination learning was investigated in goldfish. In the first experiment, there was a fixed daily change in illumination. Eight subjects were trained to operate a lever that reinforced each press with food. The period during which responses were reinforced was then progressively reduced until it was 1 hr in every 24. The final 1-hr feeding schedule was maintained over 4 weeks. The feeding period commenced at the same time each day throughout. The food dispensers were then made inactive, and a period of extinction ensued for 6 days. The pattern of responding suggested that the fish were able to exhibit temporal discrimination in anticipation of feeding time. This pattern of responding persisted for a limited number of days during the extinction procedure. The second experiment produced evidence that operant temporal discrimination could develop under continuous illumination.  相似文献

Transitioning from an acute psychiatric care setting to a less restrictive environment after a suicidal event is arguably the most critical period of suicide risk for adolescents, making comprehensive safety and coping plans for this population ever more critical. In this paper we provide theoretical and empirical rationale for the need for developmental adaptations to current safety planning procedures for suicidal adolescents, as well as the standardization of pediatric safety plans for broader use across settings that provide acute psychiatric care to adolescents. We describe how we developed the Adolescent Safety and Coping Plan (ASCP) using qualitative in-depth interviews with 20 adolescents and their parents, explain the specific components of the ASCP, and give a case example of the ASCP being used with a young adolescent and her parents. Finally, we conclude with a discussion of the barriers and facilitators of the use of the ASCP in settings that provide acute psychiatric care, as well as the need for future research to test the ASCP with diverse adolescent and family populations and settings.  相似文献

A plethora of data supports links between parenting behaviors and child anxiety, but few studies have examined factors that can contribute to variability in these relations. Adopting a biological sensitivity to context framework, this study explored the role of children's physiological stress reactivity in the links between emotion-parenting and child anxiety symptoms in a group of Chinese families. Sixty-one parent–child dyads (child Mage = 8.21 years, SD = 1.40, range = 6–12 years) participated in an acute stress protocol, from which children's physiological (cortisol and respiratory sinus arrhythmia) responses to a social speech task were recorded. Participants then completed questionnaires assessing parents’ emotion-parenting behaviors and children's anxiety symptoms. Results showed that the relation between supportive emotion-parenting and child anxiety was stronger in the context of greater child RSA suppression to acute stress, such that children higher in RSA suppression exhibited lower anxiety symptoms when supportive emotion-parenting was higher than when it was lower. Thus, these findings supported the biological sensitivity to context model. No significant moderation effect was detected for cortisol reactivity or recovery. Instead, exploratory mediation analyses showed that supportive emotion-parenting was negatively related to child anxiety via greater cortisol recovery. There was also a significant indirect path where unsupportive emotion-parenting was related to blunted cortisol recovery, which in turn was associated with higher child anxiety. The results highlight the importance of coaching parents to respond in supportive ways to children's emotional expressions, particularly in the context of greater child reactivity, to help buffer against childhood anxiety symptoms.  相似文献

We used fMRI to examine patterns of brain recruitment in 22 healthy seniors, half of whom had selective comprehension difficulty for grammatically complex sentences. We found significantly reduced recruitment of left posterolateral temporal [Brodmann area (BA) 22/21] and left inferior frontal (BA 44/6) cortex in poor comprehenders compared to the healthy seniors with good sentence comprehension, cortical regions previously associated with language comprehension and verbal working memory, respectively. The poor comprehenders demonstrated increased activation of left prefrontal (BA 9/46), right dorsal inferior frontal (BA 44/6), and left posterior cingulate (BA 31/23) cortices for the grammatically simpler sentences that they understood. We hypothesize that these brain regions support an alternate, nongrammatical strategy for processing complex configurations of symbolic information. Moreover, these observations emphasize the crucial role of the left perisylvian network for grammatically guided sentence processing in subjects with good comprehension.  相似文献

This study compares the narrative abilities of 13 children with autism, 13 children with developmental delays, and 13 typically developing children matched on language ability. Although groups did not differ in their use of causal language or internal state terms, children with autism and children with developmental delays were less likely than typical children to identify the causes of characters' internal states. Rather, they tended simply to label emotions and explain actions. Children with autism and children with developmental delays also relied on a more restricted range of evaluative devices, which both convey point of view and maintain listener involvement. In addition, the narrative abilities of children with autism were linked to performance on measures of theory of mind and an index of conversational competence, whereas this was not the case among children with developmental delays. Findings are discussed in relation to the social, cognitive, and emotional underpinnings and consequences of narrative activity.  相似文献

Vibratory roughness perception occurs when people feel a surface with a rigid probe. Accordingly, perceived roughness should reflect probe and surface geometry, exploratory speed, and force. Experiments 1 and 2 compared magnitude estimation of roughness with the bare finger and two types of probes, one designed to eliminate force moments, under the subject's active control. Experiments 3 and 4 varied speed under passive control. Log magnitude was consistently a quadratic function of log spacing between elements in the surface. The location of the function's peak was related to the drop point--that is, the spacing at which the probe can just drop between elements--which is affected by probe tip diameter, element height, and speed. Other parameters of the quadratic were affected by probe type and speed.  相似文献
