The authors evaluated the relative contributions of speed, memory, and visual scanning to Digit Symbol score in a sample of young adults (N = 87). Speed (Symbol Copy) explained 35% of Digit Symbol variance; only half of this was attributable to graphomotor speed (Name Printing), implying a role for perceptual speed. Visual-scanning tests (e.g., Symbol Scan) explained (on average) 34% of Digit Symbol variance, much of which was independent of perceptual-motor speed, establishing an important role for visual-scanning efficiency in Digit Symbol performance. By contrast, memory tests (on average) explained only 4% to 5% of Digit Symbol variance: statistically significant but clearly subsidiary, although a visual memory composite correlated more strongly with Digit Symbol. The Digit Symbol incidental learning procedures did, however, correlate moderately with other memory measures, suggesting that they are valid memory screening devices. 相似文献

The present research explores the relationship of positive symptoms, negative symptoms, and posthospital functioning to subsequent suicidal behavior over a 7 1/2-year period, and examines whether these patterns vary with diagnosis. The results support a multifactor model of suicide risk. Both psychosis and poor functioning show some relationship to later suicidal activity for both schizophrenic and schizoaffective patients. Psychosis may remain a risk factor for suicidal activity for schizoaffective patients, even when functioning is partialed out. This is in contrast to the schizophrenia patients, for whom funtioning seems to mediate the effects of psychosis on later suicidality. In general, adequacy of overall posthospital functioning mediates the effects of some risk factors on suicidal activity within different diagnostic groups. 相似文献

A considerable gap exists between the behavioral paradigm of choice set formation in route choice and its representation in route choice modeling. While travelers form their viable choice set by retaining routes that satisfy spatiotemporal constraints, existing route generation techniques do not account for individual-related spatiotemporal constraints. This paper reduces the gap by proposing a route choice model incorporating spatiotemporal constraints and latent traits. The proposed approach combines stochastic route generation with a latent variable semi-compensatory model representing constraint-based choice set formation followed by compensatory choice. The model is applied to data focusing on habitual commuting route choice behavior in morning peak hours. Results show (i) the possibility of inferring spatiotemporal constraints from considered routes, (ii) the importance of incorporating spatiotemporal constraints and latent traits in route choice models, and (iii) the linkage between spatiotemporal constraints and time saving, spatial and mnemonic abilities. 相似文献

We present a conceptualization and a 2?year program of autonomy-supportive I?CThou dialogue among teachers and students that is based on self-determination theory (Deci and Ryan in Psychol Inq 11(4):227?C268, 2000) and Buber??s (1960) philosophy. The program was applied in 18 seventh grade classes (420 students). Findings showed: (a) increases in positive emotions and in perceptions of teachers as conducting more dialogue on the relevance of studies to students?? lives, and (b) decreases in negative emotions and in classroom violence. The findings highlight the importance of autonomy-supportive I?CThou dialogue and suggest that such dialogue might help adolescents to experience studying and school as more pleasant and secure. 相似文献

Although children born preterm or low birth weight (PT LBW) are more likely to exhibit behavior problems compared to children born at term, developmental and family processes associated with these problems are unclear. We examined trajectories of maternal depressive symptoms in relation to toddler compliance and behavior problems in families with PT LBW infants. A total of 177 infants (93 boys, 84 girls) and their mothers enrolled in the study during the infant's NICU stay. Data were collected at five time points across 2 years. Assessments of maternal depressive symptoms were conducted at all time points, and toddler compliance and opposition to maternal requests and behavior problems were assessed at 2 years. Toddlers born earlier with more health problems to mothers whose depressive symptoms increased over time exhibited the most opposition to maternal requests during a cleanup task at 24 months, consistent with multiple risk models. Mothers with elevated depression symptoms reported more behavior problems in their toddlers. The study has implications for family‐based early intervention programs seeking to identify PT LBW infants at highest risk for problem behaviors. 相似文献

The psychiatric literature is divided with regard to the long-term psychological effects associated with Holocaust (Shoah) experiences because the findings of clinical and empirical studies often contradict each other. Despite case reports of emotional sequelae related to intergenerational transmission of trauma, recent empirical research has suggested that offspring of survivors of the Shoah did not differ from other children and found no evidence that traumatic experiences of survivors of the Shoah affected their children??s and grandchildren??s adjustment. To shed light on some of the differences between the empirical and clinical observations, the present study set out to compare the grandchildren of survivors of the Shoah and persons of the same age whose families had not been through the Shoah experience. This study compared the two groups on some psychological dimensions relevant to traumatic sequelae: hopelessness, temperament, personality, attitudes, and interpersonal expectations. Subjects were 124 equally divided among the Shoah survivors?? grandchildren and comparison groups; we administered to all subjects TEMPS-A Rome, Beck Hopelessness Scale, State-Trait Anger Expression Inventory, and 9AP (9 Attachment Profile). We found no differences between two groups in Hopelessness, Dysthimic/Cyclotimic/Anxious, Hyperthimic temperament, and self-perception; instead the Shoah survivors?? grandchildren have a view of the other as rejecting, hostile, submissive, insecure, unreliable, and competitive in the interpersonal relationships. The Shoah survivors?? grandchildren are similar to controls in affective temperament, hopelessness and self-perception, but they are more irritable and angry than controls, and their perception about others is deeply negative. Attribution theory was used to elucidate these findings. 相似文献

Traditionally, developmental psychology, occupational/physical therapy, and behavioral pediatrics view similar infant behaviors from temperament, sensory processing, or neurobehavioral theoretical perspectives. This study examined the relations between similar and unique summary scores of three infant assessments (Early Infancy Temperament Questionnaire - EITQ, the Infant Sensory Profile - ISP, and the NICU Network Neurobehavioral Scale - NNNS) in a healthy sample of 100, one-month-old infants. A Principal Components Analysis of selected subscale scores derived from the three assessments suggested a three-factor model. Temperament and sensory summary scores had the strongest relations on two factors: Sensory-Affective Reactivity and Engagement. A third factor had strong relations between state regulation and motor competence. This new integrative model also validates an existing model and expands explanation of infant behavior across disciplines and methods which have significant implications for assessment, intervention, and management practices. 相似文献
