Twenty mother-infant pairs were observed once a week for 7-hour periods when the infants were 2, 3, 4, and 5 weeks old. The occurrence of crying and its relationship to patterning of maternal behaviors was studied in two social contexts: while the mother was holding the infant and while she was not holding the infant. There were significant individual differences in the amount of crying in each of these contexts. The amount of crying in the two contexts was not correlated. Six variables describing forms of maternal attention throughout the 7-hour day were selected, and profiles were formed from measures of these variables. These profiles were found to vary systematically as a function of the amount of crying while the mother was holding the infant. In this context, only physical stimulation increased linearly with increased crying, whereas other forms of attention showed a U-shaped function in relation to increased crying. No relationship was found between crying while the mother was not holding the baby and patterns of interaction. We conclude that the structuring of a mother-infant relationship is reflected in the amount of crying that occurs while mother and infant are in close physical contact. The results also provide evidence that the social context for an infant's crying must be taken into account if the full adaptive value of crying is to be understood. 相似文献

Metaphors for retirement: Unshackled from schedules 总被引:1,自引:0,他引:1

This study uses metaphor analysis to examine the meanings of retirement for a group of 35 retired Canadian executives and managers. Our analysis identified eight metaphors relating to the meanings of retirement. The findings provide us with a range of insights into the experience of retirement, from loss of purpose and identity to liberation from the constraints of work to retirement being constructed as a new beginning or renaissance. Based on the accounts given by each manager, metaphors were collated and compared across retirees to reveal four distinct configurations that conceptualize retirement as exploring new horizons, searching for meaning, contributing on your own terms and putting your feet up. We discuss the implications of these metaphor configurations for understanding the consumer and producer-oriented meanings of retirement and challenge dominant career constructions of retirement as disengagement and decline. Our findings reveal that retirement appears to be better understood by incorporating future-focused and agentic forms that contribute to different types of identity work in retirement. 相似文献

This study sought to better understand the persistence of obsessive-compulsive disorder (OCD) by studying the dismissability of obsessional thoughts in individuals with OCD relative to the dismissability of panic-relevant thoughts in individuals with panic disorder with or without agoraphobia (PD/A). Individuals with a principal diagnosis of OCD (n = 25) or PD/A (n = 25) completed a thought replacement task in which they replaced a primary obsession (target thought for the OCD group) or a primary panic-relevant thought (target thought for the PD/A group), with a neutral thought, signaling when the target thought occurred and when the neutral thought was in mind. The OCD group had more target thoughts and appraised the recurrence of the target thought more negatively. Whereas mood state did not change in the PD/A group, it declined in the OCD group, and this change was predicted by negative appraisal of target thought recurrences, but not amount of time thinking the target thought. These findings suggest that in vivo appraisal of the recurrence of obsessions may be a unique, key mechanism in the persistence of OCD and that the identification and exploration of appraisal of thought recurrences may be an especially important target in its treatment. 相似文献

The purpose of this study was to explore the relationship of spiritual beliefs and involvement with anger and stress in early
adolescents. Early adolescents (n = 53) completed the Spiritual Involvement and Beliefs Scale (Hatch et al. 1998), the State-Trait Anger Expression Inventory (Spielberger 1999), and the Perceived Stress Scale (Cohen and Williamson 1988). Contrary to expectations, spirituality was significantly and positively related to anger and stress. Implications and possible
explanations for the unanticipated findings in this study are discussed. 相似文献

The purpose of this study was to move beyond the traditional specificity model of autobiographical memory (ABM) and to examine the content of memories with a focus on disorder and schema-relevant content. The sample (N = 82) included 25 patients with major depressive disorder (MDD), 24 with social phobia (SP), and 33 with panic disorder with agoraphobia (PDA) who were referred to a large outpatient clinic for group treatment of depression or anxiety. Participants completed the Autobiographical Memory Test (AMT) and Beck Depression Inventory-II as part of the clinical intake process. Responses to the AMT were coded for disorder-specific content based on diagnostic criteria for each disorder as well as for schema-relevant (sociotropy vs. autonomy) content. A repeated measures multiple analysis of variance demonstrated significant differences in disorder-specific content, with patients in the MDD group reporting more depressotypic ABMs than those in the PDA group but not the SP group. Similarly, in the analysis of schema-relevant content, significant differences were found between MDD and PDA regarding the presence of autonomy-based ABM ratings. Study results provide partial support for the cognitive specificity hypothesis with ABM content. The results are discussed in relation to the cognitive models of depression and anxiety. 相似文献

This study's primary goal was to evaluate the use of performance feedback procedures delivered to a classroom team to increase daily data collection. Performance feedback (PFB) was delivered to four classroom teams responsible for the daily collection of data representing student performance during prescribed instructional activities. Using a multiple-baseline design, the effects of the team performance-feedback were evaluated for the target student, and for generalization to data collection for all classroom students. A secondary question evaluated if student on-task behavior correlated with increased data collection. Finally, social validity was investigated to evaluate team satisfaction with the PFB intervention. The results demonstrate improved data collection across all four classroom teams for the target student in each classroom and generalization within classrooms to all remaining students. Slight increases in student on-task behavior were observed in three of the four classrooms, and teacher satisfaction ratings were high. 相似文献

Connine, Blasko, and Hall (Journal of Memory and Language 30:234–250, 1991) suggested that within a 1-second temporal window, subsequent biasing information can influence the identification of a previously spoken word. Four experiments further explored this hypothesis. Our participants heard sentences in which an ambiguous target word was followed less than or more than a second later by a word biased in favor of either the target word or another word. Overall, the effects of the contextual biases on responding, measured using phonemic restoration and phoneme identification, were almost as large after 1 second as before 1 second. The implications of these results for defining the window of contextual effects are discussed. 相似文献
