Memory is susceptible to distortions. Valence and increasing age are variables known to affect memory accuracy and may increase false alarm production. Interaction between these variables and their impact on false memory was investigated in 36 young (18-28 years) and 36 older (61-83 years) healthy adults. At study, participants viewed lists of neutral words orthographically related to negative, neutral, or positive critical lures (not presented). Memory for these words was subsequently tested with a remember-know procedure. At test, items included the words seen at study and their associated critical lures, as well as sets of orthographically related neutral words not seen at study and their associated unstudied lures. Positive valence was shown to have two opposite effects on older adults' discrimination of the lures: It improved correct rejection of unstudied lures but increased false memory for critical lures (i.e., lures associated with words studied previously). Thus, increased salience triggered by positive valence may disrupt memory accuracy in older adults when discriminating among similar events. These findings likely reflect a source memory deficit due to decreased efficiency in cognitive control processes with aging. 相似文献

Is a Worried Citizen a Good Citizen? Emotions,Political Information Seeking,and Learning via the Internet 总被引:4,自引:1,他引:3

In this study we explore the mediating role of emotions in the process of becoming a politically informed citizen. Contrary to previous studies, we expect that anger and anxiety will have much different effects on this process. We suspect the role of anxiety is somewhat unique even among negative emotions as mediator of the causal effect of political threats on information seeking and learning. In addition, we speculate that anxiety should improve the quality of information seeking, not just its quantity. In one experiment, we induce emotions directly and find that while anger, enthusiasm, and anxiety can lead people to claim they will pay attention to the campaign, anger actually depresses total information seeking. In a second experiment, we examine the impact of realistic political threats and find that exposure triggers several emotions but that only anxiety boosts information seeking and learning. 相似文献

Infants can detect information specifying affect in infant- and adult-directed speech, familiar and unfamiliar facial expressions, and in point-light displays of facial expressions. We examined 3-, 5-, 7-, and 9-month-olds' discrimination of musical excerpts judged by adults and preschoolers as happy and sad. In Experiment 1, using an infant-controlled habituation procedure, 3-, 5-, 7-, and 9-month-olds heard three musical excerpts that were rated as either happy or sad. Following habituation, infants were presented with two new musical excerpts from the other affect group. Nine-month-olds discriminated the musical excerpts rated as affectively different. Five- and seven-month-olds discriminated the happy and sad excerpts when they were habituated to sad excerpts but not when they were habituated to happy excerpts. Three-month-olds showed no evidence of discriminating the sad and happy excerpts. In Experiment 2, 5-, 7-, and 9-month-olds were presented with two new musical excerpts from the same affective group as the habituation excerpts. At no age did infants discriminate these novel, yet affectively similar, musical excerpts. In Experiment 3, we examined 5-, 7-, and 9-month-olds' discrimination of individual excerpts rated as affectively similar. Only the 9-month-olds discriminated the affectively similar individual excerpts. Results are discussed in terms of infants' ability to discriminate affect across a variety of events and its relevance for later social-communicative development. 相似文献

The current research uses a novel methodology to examine the role of semantics in reading aloud. Participants were trained to read aloud 2 sets of novel words (i.e., nonwords such as bink): some with meanings (semantic) and some without (nonsemantic). A comparison of reading aloud performance between these 2 sets of novel words was used to provide an indicator of the importance of semantic information in reading aloud. In Experiment 1, in contrast to expectations, reading aloud performance was not better for novel words in the semantic condition. In Experiment 2, the training of novel words was modified to reflect more realistic steps of lexical acquisition: Reading aloud performance became faster and more accurate for novel words in the semantic condition, but only for novel words with inconsistent pronunciations. This semantic advantage for inconsistent novel words was again observed when a subset of participants from Experiment 2 was retested 6-12 months later (in Experiment 3). These findings provide support for a limited but significant role for semantics in the reading aloud process. 相似文献

Despite the importance of social support across the lifespan and extensive research on supportive communication between adults, little is known about how children or adolescents respond to the comforting efforts of their peers. The current study was designed to examine how 5th, 7th, and 9th graders evaluate six peer comforting strategies (sympathy, account giving, companionship, advice, optimism, and minimization) and to assess moderating effects of age, gender, and situation. Participants (N= 292) read scenarios involving a social rejection or academic failure and rated messages for affective improvement and perceived caring. Results indicated that companionship was the most positively evaluated strategy on both dependent variables, whereas minimization and account were least positively evaluated; sympathy, advice, and optimism received intermediate evaluations. These results were somewhat moderated by age, gender, and situation. Results are discussed with respect to potential differences between adult and tween evaluations and expectations in comforting interactions. 相似文献

This research examines women's narratives regarding the experiences that lead to becoming, sustaining, and challenging active community leaders. Seventeen women neighborhood leaders, age 28 to 73 years, completed in-depth interviews. Qualitative thematic content analyses identified prominent themes in participants' responses that were subsequently linked to a generativity framework. Analyses revealed that leaders reported circuitous rather than linear paths of emerging community participation and growing up among others who demonstrated an ethos of care in informal as well as formal community practices. Women's initial community engagement was most often in response to invitations to address community needs. Both communal and agentic rewards and challenges to community involvement were identified. Based upon the findings, strategies for promoting and sustaining women's community leadership are identified. 相似文献

Past research has identified a host of benefits associated with volunteering and community involvement, yet involvement appears to be on the decline in recent years. We tested the effectiveness of an intervention designed to encourage involvement. We provided young adolescents with information about volunteer opportunities, benefits and ways to overcome barriers to involvement. Adolescents who participated in the volunteering intervention reported greater involvement intentions than control participants. In addition, mediation analyses indicated that adolescents in the volunteering intervention based their self‐worth to a greater degree on virtuous behaviour, which in turn predicted their involvement intentions, especially in the helping domain.

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task. 相似文献

We describe changes in adaptive functioning for children enrolled in the Intensive Mental Health Program (IMHP), an innovative
model for serving children with the most severe forms of SED. Most children show marked improvements in multiple indicators
of role performance and symptomatology. Although a high risk, high need group, most children attended school regularly and
lived with a stable caregiver at discharge. 相似文献

We examined factors related to treatment responders (n = 35) and nonresponders (n = 16) in a group of 51 children admitted to the Intensive Mental Health Program (IMHP). Children’s response to treatment
was coded based on their functioning at intake and discharge using total CAFAS scores. Demographic variables, length of treatment,
number of diagnoses and medications, and history of physical/emotional abuse or neglect did not significantly distinguish
between responders and nonresponders. Nonresponders were more likely to present with a history of suspected or confirmed sexual
abuse, internalizing diagnoses, or comorbid internalizing and externalizing diagnoses. Although the small sample size may
limit interpretations, our findings indicate treatment programs need augmentation when children with serious emotional disturbances
(SED) may be at risk for not responding to interventions. 相似文献
