GSR records were obtained for four groups of 20 Ss. Group I was presented with a series of four different lights (amber, blue, green, and white) appearing 20 times each, in apparent random order. The procedure was similar for the other three groups except that in group 2, a novel stimulus (a red light) appeared instead of the sixth amber light; in group 3, it appeared instead of the 11th amber light; and, in group 4, it appeared instead of the 16th amber light. Typical GSR adaptation phenomena were observed in all groups. The introduction of the novel stimulus appeared to have no effect on the course of GSR adaptation. 相似文献

The goal of the present study was to evaluate the role of parent adherence in the Collaborative Life Skills (CLS) program, a multicomponent school-home intervention, for predicting child and parenting outcomes. A sample of 129 children (63% male; M age = 8.22, SD = 1.10; grades 2–5) with attention-deficit/hyperactivity disorder (ADHD) and their parents participated in CLS, which included 10 weekly behavioral parent training group sessions. Each week, parents provided information on their CLS skill use between sessions (at home) as part of the intervention. Outcome measures included parent and teacher ratings of child behavior and parenting at post-intervention and 6 months follow-up. Growth mixture models examining weekly parent skill use trajectories throughout the intervention significantly predicted parent- and teacher-reported outcomes including parent-rated child behavior, teacher-rated academic competence, and positive parenting behaviors. Fifty-two percent of parents displayed moderate skill use throughout the intervention, whereas the remaining parents had either low (20%) or high (28%) initial levels of use but demonstrated high skill utilization by the middle of the intervention. Results highlight the importance of examining individual differences in parents between session strategy use for behavioral parent training interventions targeting child and parenting outcomes. 相似文献

ABSTRACT This study explored pre-bereavement personality traits and gender as predictors of post-widowhood mortality risk, using newly derived life span data for participants originally recruited for Lewis Terman's classic study of the gifted. Personality traits measured in 1940 were used to predict mortality risk from 1940 through 2004 for married participants who were either widowed between 1940 and 1986 or who remained married. Results indicated that widowhood predicted a decrease in mortality risk for these (intelligent) individuals (relative hazard [ rh ]=0.68, N =843, p <.001) and neuroticism significantly moderated this effect. Specifically, neuroticism in young adulthood was significantly associated with decreased mortality risk among men who were later widowed ( rh =0.50, N =66, p <.02) but not among women or consistently married men. Conclusions reveal the importance of personality–situation interactions and the adoption of a long-term perspective. 相似文献

In two experiments, participants were trained to recognize a playground scene from four vantage points and were subsequently
asked to recognize the playground from a novel perspective between the four learned viewing perspectives, as well as from
the trained perspectives. In both experiments, people recognized the novel view more efficiently than those that they had
recently used in order to learn the scene. Additionally, in Experiment 2, participants who viewed a novel stimulus on their
very first test trial correctly recognized it more quickly (and also tended to recognize it more accurately) than did participants
whose first test trial was a familiar view of the scene. These findings call into question the idea that scenes are recognized
by comparing them with single previous experiences, and support a growing body of literature on the existence of psychological
mechanisms that combine spatial information from multiple views of a scene. 相似文献

A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co‐vary with other non‐verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behaviors. We used a computer‐generated animated pedagogical agent to control both verbal and non‐verbal behavior. Children viewed lessons on mathematical equivalence in which an avatar either gestured or did not gesture, while eye gaze, head position, and lip movements remained identical across gesture conditions. Children who observed the gesturing avatar learned more, and they solved problems more quickly. Moreover, those children who learned were more likely to transfer and generalize their knowledge. These findings provide converging evidence that gesture facilitates math learning, and they reveal the potential for using technology to study non‐verbal behavior in controlled experiments. 相似文献

Young children show competence in reasoning about how ownership affects object use. In the present experiments, we investigate how influential ownership is for young children by examining their explanations. In three experiments, we asked 3‐ to 5‐year‐olds (N = 323) to explain why it was acceptable (Experiments 1–3) or unacceptable (Experiment 2 and 3) for a person to use an object. In Experiments 1 and 2, older preschoolers referenced ownership more than alternative considerations when explaining why it was acceptable or unacceptable for a person to use an object, even though ownership was not mentioned to them. In Experiment 3, ownership was mentioned to children. Here, younger preschoolers frequently referenced ownership when explaining unacceptability of using an object, but not when explaining why using it was acceptable. These findings suggest that ownership is influential in preschoolers' explanations about the acceptability of using objects, but that the scope of its influence increases with age. 相似文献

We examined whether the generalized sense of power—the belief that one is able to influence others in one's various social relationships—serves as a psychological resource that enables leadership in high-stakes, unfamiliar group challenges, such as emergencies or crises. We studied current and prospective humanitarian aid professionals (N = 180) during a major field training exercise: a three-day, immersive simulated humanitarian crisis. Individuals who entered the simulated crisis with a greater sense of power in their social relationships experienced lower stress (anxiety), behaved more assertively, and left the simulation with a relatively heightened desire to lead, despite not being deemed better leaders by their teammates. Lacking an initial sense of power was associated with experiences (e.g., feeling timid) that undermined the desire to lead. These results suggest that the psychological sense of power is a key leadership resource, without which one may be at risk of self-selecting out of leadership. 相似文献
