Abstract

Adults' narratives were analysed to study life-span changes in their structure. The narratives were collected from a group of adults in their 60s, 70s, and 80s. Four separate analyses were performed on the narratives' (1) hierarchical structure, (2) syntactic structure, (3) propositional content, and (4) cohesion. Age-group differences were obtained for the measures of hierarchical structure, syntactic structure, and cohesion. Further analyses revealed that the structural complexity of the narratives influenced their syntactic structure and cohesion. Interactions between the effects of age group and structural complexity suggest that elderly adults minimise the syntactic complexity of their narratives, reducing their cohesion, when producing structurally complex narratives. Finally, ratings of the quality of the narratives were strongly correlated with their structural complexity, suggesting that telling a “good” story involves constructing complex plots.  相似文献

In this article, the authors describe the refinement and preliminary evaluation of the Dimensions of Change in Therapeutic Community Treatment Instrument (DCI), a measure of treatment process. In Study 1, a 99-item DCI, administered to a cross-sectional sample of substance abuse clients (N = 990), was shortened to 54 items on the basis of results from confirmatory factor analyses and item response theory invariance tests. In Study 2, confirmatory factor analyses of the 54-item DCI, completed by a longitudinal cohort of 993 clients, established and validated an 8-factor solution across 2 subpopulations (adults and adolescents) and 2 time points (treatment entry and 30-days postentry). The results of the 2 studies are encouraging and support use of the 54-item DCI as a tool to measure treatment process.  相似文献

Dopamine is critical for directing goal-oriented behavior. We investigated dopamine D2 receptor involvement in reversal learning and reinforcement efficacy in mice lacking functional dopamine D2 receptors and their heterozygous and wild-type littermates. Mice discriminated between two odors to receive a food reinforcer: One odor signaled a reinforcer (S+); the other odor signaled no reinforcer (S). After mice learned the S+/S relationship, we inverted the reinforcement contingencies. The necessary number of trials to relearn the new reinforcement contingencies served as our index of reversal learning. Mice lacking functional dopamine D2 receptors repeatedly failed to inhibit previously reinforced responses during reversal trials. In a separate experiment, mice responded for reinforcers on a progressive ratio schedule of reinforcement. Mice lacking functional dopamine D2 receptors earned significantly fewer reinforcers than did heterozygous mice. Our results suggest that dopamine D2 receptors regulate reversal learning and influence the reinforcing efficacy of natural rewards.  相似文献

We used a daily process design and multilevel modeling to examine the role of borderline personality features in the day-to-day stability of college students' negative affect and self-esteem and their reactivity to interpersonal stressors. At the end of each day for two weeks, students completed a checklist of daily stressors and measures of state affect and self-esteem. We predicted that high scores on a measure of borderline features would be related to more daily interpersonal stressors, greater negative affective and self-esteem reactivity to these stressors, and less day-to-day carryover of negative mood and self-esteem. The first and third hypotheses were supported, but not the second. The findings demonstrate the utility of a daily process methodology and multilevel modeling to study the day-to-day functioning of individuals with borderline features.  相似文献

The utility of single-case vs. group studies has been debated in neuropsychology for many years. The purpose of the present study is to illustrate an alternative approach to group studies of aphasia, in which the same symptom dimensions that are commonly used to assign patients to classical taxonomies (fluency, naming, repetition, and comprehension) are used as independent and continuous predictors in a multivariate design, without assigning patients to syndromes. One hundred twenty-six Italian-speaking patients with aphasia were first classified into seven classic aphasia categories, based on fluency, naming, auditory comprehension, and repetition scales. There were two goals: (1) compare group analyses based on aphasia types with multivariate analyses that sidestep classification and treat aphasic symptoms as continuous variables; (2) present correlation-based outlier analyses that can be used to identify individuals who occupy unusual positions in the multivariate "symptom space." In the service of the first goal, group performance on an external validation measure (the Token Test) was assessed in three steps: analyses of variance based on aphasia type, regressions using the same cut-offs for fluency, naming, comprehension and repetition as independent but dichotomous predictors, and regressions using the same subscales as continuous predictors (with no cut-offs). More variance in Token Test performance was accounted for when symptoms were treated as continuous predictors than with the other two methods, though use of independent but dichotomous predictors accounted for more variance than aphasia taxonomies. Thus, if we by-pass classical taxonomies and treat patients as points in a multidimensional symptom space, better predictions are obtained. Outlier analyses show that group results depend on heterogeneity among patients, which can be used as a search tool to identify potentially interesting dissociations. Hence this multivariate group approach is complementary to and compatible with single-case methods.  相似文献

There exists considerable research on the effects of prenatal maternal stress on offspring. Animal studies, using random assignment to experimental and control groups, demonstrate the noxious effects of prenatal maternal stress on physical, behavioural and cognitive development. The generalizability of these results to humans is problematic given that cognitive attributions moderate reactions to stressors. In humans, researchers have relied upon maternal anxiety or exposure to life events as proxies for the stressors used with animals. Yet, the associations between maternal anxiety or potentially non-independent life events and problems in infants are confounded by genetic transmission of temperament from mother to child. We summarize the literature on prenatal maternal stress and infant cognitive development, leading to the conclusion that the human literature lacks the ability to separate the effects of the objective exposure to a stressor and the mother's subjective reaction. We then describe our prospective Project Ice Storm in which we are following 150 children who were exposed in utero to a natural disaster. We demonstrate significant effects of the objective severity of exposure on cognitive and language development at age two years with important moderating effects of the timing during pregnancy. The implications of our findings are discussed.  相似文献

Presents a comment on "Psychological Treatments" by D. H. Barlow. In his article, Barlow pointed to the need "to solidify the identification of psychology as a health care profession" by changing the terminology of practice in the health care context from psychotherapy to psychological treatments and suggested that the only persons qualified to carry out such interventions are doctoral-level psychologists. Unfortunately, there was no discussion of the health care professionals who already provide psychological treatments in health care settings and their contribution to the evidence base supporting such treatment. The authors find several aspects of the article to be problematic. Overall, the authors feel that suggesting that psychology should claim treatment of psychological disorders and psychological components of physical disorders in health care settings as exclusively its own domain ignores the research and clinical contributions of others.  相似文献

The sudden traumatic loss of a spouse equates to an assault on self and the loss of both an internal and external self-object. Mourning requires compensatory self-objects to help in the restoration of self and in the creation of new self-structure. The catastrophe of 9/11 not only assaulted thousands with unanticipated traumatic loss, but also devastated the usual networks of support. In this light, the bereavement group became a valuable venue for self-restoration and recovery. In her group work with 9/11 corporate and uniformed service widows, the author applies a self-psychology perspective that considers that empathic immersion not only affords safety and stabilization, but the opportunity to have self-object needs met in a process that restores and develops self-structure. She proposes the bereavement group as a cohesive self-object milieu serving mirroring, twinship, and idealizing needs. Drawing upon clinical examples, she illuminates the capacity of the group to establish safety, regulate affect, reduce isolation and shame, rekindle memory, and foster coping skills. As such, the group affords a restoration of the assaulted self, an integration of the loss, and an emerging redefinition of self.  相似文献

Random effects models were used to examine the association between behavioral disturbances in persons with Alzheimer's disease (N = 90) and caregiver depressive symptoms at 2-month intervals over an 18-month period. There was substantial variability in trajectories of change in caregiver depressive symptoms over time but no systematic increase in distress despite increased severity of dementia symptoms. Total behavioral disturbances were associated with higher levels of caregiver depressive symptoms: this effect was primarily attributable to aggressive behaviors. No consistent departure from linearity was evident in the relationship between behavior and depression over time.  相似文献
