Young (17-22 years) and older (61-86 years) persons underwent classical conditioning of the eye-blink response to a tone conditioned stimulus (CS) and an airpuff unconditioned stimulus (UCS) at 1 of 3 interstimulus intervals (ISIs; 400, 650, and 900 ms). As in a previous study, older subjects conditioned more slowly and emitted fewer conditioned responses at the optimal 400-ms ISI. At longer ISIs, however, this age-related disruption of classical conditioning was attenuated. These differences in conditioning were not due to nonassociative factors, such as sensitivity to the tone CS or airpuff UCS or to differences in spontaneous blink rate, nor were they due to differences in general cognitive abilities. The results are discussed in terms of the role of temporal relationships between stimuli in conditioning across the life span. 相似文献

This article examines the creation of a network of diverse religious leadership in a Midwest suburb where the intersection of religion and national pride fomented a community-wide conflict. Activated during a heated controversy over displaying a Christmas tree in a public school, the Network became a laboratory for testing viable strategies for community healing. The case of a Jewish student suspended for fighting when taunted for not singing Christmas Carols became a catalyst for debating what is religious, what is secular, and what is culturally American. The interaction of the key players is noted; educators, religious leaders, students and their families, particularly the mothers who regularly interacted across religious boundaries. The article describes the Network's experiment with deploying resources that accommodated diverse experiences of religion and patriotism, historically and culturally, within an American context. 相似文献

Infants and toddlers discriminate amount: are they measuring? 总被引:1,自引:0,他引:1
Four experiments that show an early ability to encode and retain information about extent are presented. We found that infants discriminate between the heights of dowels in a habituation task. We also found that toddlers discriminate between heights on a choice task in which a target dowel is presented and removed and they then choose between the target and a foil. Until 4 years of age, however, discrimination occurs only in the presence of a perceptually salient standard. Adults do not require a perceptually present standard; they can assess extent across temporal or spatial gaps by imposing a standard (measure). The present findings indicate that infants and toddlers do not possess an adult ability to establish extent, but that they do possess a skill that provides a start point for this important intellectual achievement. 相似文献

Given only information that a youth who could have been tried as either an adult or as a juvenile was being tried as an adult for murder, 218 undergraduate mock jurors were able to form consistent impressions of the defendant. A very high percent of our mock jurors included a criminal or juvenile justice history as part of that impression. A very large majority of the mock jurors also said that knowledge of that criminal history would be relevant to their vote of guilty. Almost all mock jurors said they would be influenced toward voting guilty by knowledge of a previous criminal history. Few of the other components of the impression were so closely correlated with a judgment of relevance, or with a judgment that they would be influenced toward voting guilty by the knowledge of that component of the stereotype. The effect is relatively specific to knowledge of a previous criminal history. The study has limited ecological validity. Nonetheless, we raise questions about whether the fact that a youth is put on trial as an adult is inherently prejudicial, and violates the Sixth Amendment right to an impartial jury. 相似文献

We investigated age-related effects in recall of emotional and neutral autobiographical memories. Protocols were scored according to episodic and non-episodic detail categories using the Autobiographical Interview. Young adults recalled a greater number of episodic details compared to older adults, whereas older adults recalled more semantic details, replicating previous findings. Both young and older adults' emotional memories contained more overall detail than neutral ones, with the enhancement from emotion-specific to episodic details, but this did not alter the effect of age group on the pattern of episodic and semantic details. However, the age effect on episodic details was attenuated for neutral autobiographical memories. The findings suggest that age differences for emotional autobiographical recollection might reflect a more general pattern of age-related changes in memory, with impaired recall of episodic components and relative sparing of semantic aspects of autobiographical memory in older adults when compared to young adults. 相似文献

Activities that require focused attention, such as reading, are declining among American youth, while activities that depend on multitasking, such as instant messaging (IMing), are increasing. We hypothesized that more time spent IMing would relate to greater difficulty in concentrating on less externally stimulating tasks (e.g., academic reading). As hypothesized, the amount of time that young people spent IMing was significantly related to higher ratings of distractibility for academic tasks, while amount of time spent reading books was negatively related to distractibility. The distracting nature and the context of IMing in this population are described. 相似文献

Children regulate negative emotions in a variety of ways. Emotion education programs typically discourage emotional disengagement and encourage emotional engagement or "working through" negative emotions. The authors examined the effects of emotional disengagement and engagement on children's memory for educational material. Children averaging 7 or 10 years of age (N=200) watched either a sad or an emotionally neutral film and were then instructed to emotionally disengage, instructed to engage in problem solving concerning their emotion, or received no emotion regulation instructions. All children then watched and were asked to recall the details of an emotionally neutral educational film. Children instructed to disengage remembered the educational film better than children instructed to work through their feelings or children who received no emotion regulation instructions. Although past research has indicated that specific forms of emotional disengagement can impair memory for emotionally relevant events, the current findings suggest that disengagement is a useful short-term strategy for regulating mild negative emotion in educational settings. 相似文献

Sender demeanor is an individual difference in the believability of message senders that is conceptually independent of actual honesty. Recent research suggests that sender demeanor may be the most influential source of variation in deception detection judgments. Sender demeanor was varied in five experiments (N = 30, 113, 182, 30, and 35) to create demeanor–veracity matched and demeanor–veracity mismatched conditions. The sender demeanor induction explained as much as 98% of the variance in detection accuracy. Three additional studies (N = 30, 113, and 104) investigated the behavioral profiles of more and less believable senders. The results document the strong impact of sender effects in deception detection and provide an explanation of the low‐accuracy ceiling in the previous findings. 相似文献
