Factor analyses were used to develop new scales for the Multiple Affect Adjective Check List (MAACL) measuring anxiety, depression, hostility, positive, and sensation-seeking affects. Anxiety, depression, and hostility scales were moderately intercorrelated and a combined score called “dysphoria” was formed from their addition. Positive and sensation-seeking affects were also correlated and combined in a summary score (PASS). The dysphoric and PASS scores were not highly correlated. The number of items checked correlated highly with the positive affect scale, moderately with sensation seeking, and relatively low with the negative affect scales. Internal reliabilities were high and retest reliabilities were low, in conformance with the model for state scales. The anxiety score increased and the positive affect score and number of items checked decreased just prior to a classroom examination. Further plans for scale development are discussed.  相似文献

In this paper we examine mothers' representations of one form of trauma to the caregiving system: the experience of receiving a diagnosis of a chronic illness or disability in their child. An interview and classification system was used with 91 mothers of children ages 15–50 months with cerebral palsy or epilepsy. Mothers were classified as Resolved or Unresolved with respect to their child's diagnosis and grouped into subcategories within these major groups. Roughly half of these mothers were classified as Unresolved with respect to their child's diagnosis. Diagnosis type, severity of condition, developmental age, and time since receiving diagnosis were all unrelated to the distribution of Resolved/Unresolved classifications. Patterns of resolution in which cognitive strategies predominated were the most frequent form within the Resolved classification. Findings provide support for the organizational nature of caregiving representations as well as a number of implications for clinical practice.  相似文献

Delayed attentional engagement in the attentional blink   总被引:6,自引:0,他引:6  
Observers often miss the 2nd of 2 visual targets (first target [T1] and second target [T2]) when these targets are presented closely in time; the attentional blink (AB). The authors hypothesized that the AB occurs because the attentional response to T2 is delayed by T1 processing, causing T2 to lose a competition for attention to the item that follows it. The authors investigated this hypothesis by determining whether the AB is attenuated when T2 is precued. The results from 4 experiments showed that the duration and magnitude of the AB were substantially reduced when T2 was precued. The observed improvement in T2 report did not occur at the expense of T1 report, suggesting that processing of T1 was already completed or was at least protected when the cue was presented. The authors conclude that, during the AB, there is a delay between detection and the selection of target candidates for consolidation in short-term memory.  相似文献

The authors examined the role of family factors and the course of schizophrenia by carrying out additional assessments and analyses in 2 previously published studies of Mexican American and Anglo American patients and families. The authors found partial support for an attributional model of relapse for families who are low in emotional overinvolvement. Attributions of control, criticism, and warmth together marginally predicted relapse. The data also indicated that for Mexican Americans, family warmth is a significant protective factor, whereas for Anglo Americans, family criticism is a significant risk factor. These findings suggest that the sociocultural context shapes the pathways by which family processes are related to the course of illness. Moreover, the warmth findings suggest that families may contribute to preventing relapse.  相似文献

Inhibition of return to occluded objects   总被引:2,自引:0,他引:2  
Since many visual objects are vulnerable to occlusion, an active process that tracks objects behind occluders confers considerable ecological validity to the visual system. We studied this possibility by testing whether inhibition of return can be observed with occluded objects. In our experiments, two moving objects disappeared or reappeared behind occluders while a cue and a probe were presented. Contrary to the results of a previous study (Tipper, Weaver, Jerreat, & Burak, 1994), responses were consistently delayed for the cued object that was occluded when it was cued (Experiment 1), when it was probed (Experiment 2), or both (Experiment 3). These results suggest that attention can select occluded objects that are out of view. Our findings are in line with prior studies that have demonstrated similar perceptual/attentional effects for occluded objects, as well as for visible objects.  相似文献

The visual environment is extremely rich and complex, producing information overload for the visual system. But the environment also embodies structure in the form of redundancies and regularities that may serve to reduce complexity. How do perceivers internalize this complex informational structure? We present new evidence of visual learning that illustrates how observers learn how objects and events covary in the visual world. This information serves to guide visual processes such as object recognition and search. Our first experiment demonstrates that search and object recognition are facilitated by learned associations (covariation) between novel visual shapes. Our second experiment shows that regularities in dynamic visual environments can also be learned to guide search behavior. In both experiments, learning occurred incidentally and the memory representations were implicit. These experiments show how top-down visual knowledge, acquired through implicit learning, constrains what to expect and guides where to attend and look.  相似文献
