Both the accuracy of category-size information and its use during the retrieval of categorized materials were investigated among kindergarten (5-year-old) and third-grade (8-year-old) children. Subjects were asked for free recall of a 34-item, categorized list wherein eight categories contained varying numbers of items. Subjects recalled items under either limited-time or unlimited-time conditions. Additionally, subjects were tested under one of three instructions: they were provided with the size of each category (Informed group), they were asked to estimate the size of each category (Estimation group), or they were given standard free recall instructions. Analysis of both the amount recalled and intercategory pause times indicated that third-graders' use of category size information was spontaneous, while kindergartners used the size information only when explicitly provided with it or asked for size estimates. Also, kindergartners' estimates of category size were much more in error than those of third-graders, although both groups erred on the side of underestimation. Importantly, when recall time limitations made the use of exhaustive category search less appropriate, third-graders were more apt to modify their search strategies.  相似文献

Free-recall learning and organization were measured for 3rd, 7th, and 11th graders under conditions which varied the type and amount of task structure. Task structure for the input or list-presentation phase was manipulated by using a random, constant, or alphabetic item sequence across trials. Task structure for the output or recall phase was manipulated by providing standard instructions or instructions which suggested the possible use of an alphabetic ordering scheme. Recall performance and organization showed an interaction between age and both manipulations of task structure. The 3rd graders required the maximal amount of task structure (alphabetic order with alphabetic instructions) to demonstrate recall facilitation relative to the completely unstructured control condition. The 7th graders showed recall facilitation for intermediate and high levels of task structure, and the 11th graders showed recall facilitation for low, intermediate, and high levels of task structure. The results are related to current hypotheses about developmental changes in recall performance and their relationship to changes in the systematic use of organizational strategies.  相似文献

Affective touch is gentle slow stroking of the skin, which can reduce experimentally induced pain. Our participant, suffering from Parkinson's Disease and chronic pain, received 1 week of non-affective touch and 1 week of affective touch as part of a larger study. Interestingly, after 2 days of receiving affective touch, the participant started to feel less pain. After 7 days, the burning painful sensations fully disappeared. This suggest that affective touch may reduce chronic pain in clinical populations.  相似文献

Loneliness is a salient risk factor for obesity, emotional eating, and poor diet. Because adolescents and parents are embedded within a family unit, their experiences of loneliness may be associated with both their own and one another's behaviors. To examine the extent to which parent and child loneliness predict body mass index (BMI) and eating in parents and adolescents, an actor–partner interdependence model of loneliness, eating, and BMI in adolescent–parent dyads was analyzed. There were actor effects among adolescents such that greater loneliness was positively associated with emotional eating and BMI‐z, and there was an actor effect among parents such that higher loneliness was positively related to emotional eating. There was a partner effect among adolescents such that greater parental loneliness was positively associated with adolescent emotional eating, and there was a partner effect among parents such that higher adolescent loneliness was positively associated with parental emotional eating. There were several actor–partner effects for loneliness and junk food in dyads with boys. Findings highlight the importance of dyadic models of loneliness in adolescent–parent dyads.  相似文献

This article applies structural ritualization theory (SRT) to identify different rituals and determine their importance in the daily lives of social networking sites (SNS) users, especially Facebook users. A mixed‐methods approach of in‐depth interviews and netnography viewed through the lens of SRT allowed us to identify and analyze the types of rituals users engaged in, and how these rituals impacted users and evolved over time. During customer journeys on the SNS of Facebook, users shared daily ritual practices in distinct behavioral stages. Production and consumption of these daily rituals are important to marketers in SNS platform design for building and maintaining connectivity between users and the SNS platform.  相似文献

Stressful situations may contribute to pathological states in elderly people facing harmful events. This study investigated the relationships between adopting appropriate coping strategies, transforming circumstances to personal preferences or adjusting personal preferences to situational constraints, and the efficiency of cognitive functioning in an elderly sample of 121 residents drawn from a rural community in southern Italy. They were administered the Mini-Mental State Examination, the Tenacious Goal Pursuit, Flexible Goal Adjustment, and Coping Inventory for Stressful Situations. Intercorrelations of scores suggested that facing stressful situations is somewhat associated with efficient cognitive functioning and coping strategies that ensure a wide range of solutions.  相似文献

The effect of SpeechEasy on stuttering frequency during speech produced in a laboratory setting was examined. Thirteen adults who stutter participated. Stuttering frequencies in two baseline conditions were compared to stuttering frequencies with the device fitted according to the manufacturer's protocol. The fitting protocol includes instructions for deliberate use of vowel prolongation. Relative to the initial baseline condition, stuttering was reduced by 74%, 36%, and 49% for reading, monologue, and conversation, respectively. In comparison, stuttering was reduced by 42%, 30%, and 36%, respectively with the device in place, but before participants were instructed to deliberately prolong vowels. Examination of individual response profiles revealed that although stuttering reduced in the device compared to the baseline conditions during at least one of three speech tasks for most participants, degree and pattern of benefit varied greatly across participants. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) discuss recent research in altered auditory feedback that led to the development of SpeechEasy, (2) analyze and describe issues related to evaluating the treatment benefits of fluency aids, and (3) summarize the range of outcomes that were observed with SpeechEasy in this study.  相似文献
