A previous study evaluating receptive language after unilateral brain damage in childhood hypothesized lateralized attention and memory deficits without direct measurement. Our study directly measured attention, memory, and language in order to evaluate empirically the severity and laterality of sequelae. The performances of 11 individuals with a unilateral ischemic-lesion (7 right and 4 left hemisphere) were compared to controls matched on age, sex, and socioeconomic status. Results suggest subtle but persistent deficits in verbal memory, functional memory, and speed of processing after a lesion to either hemisphere. Lesions sustained before two years of age were associated with the lowest IQ scores. Our findings provide support for a configural representation of language that can to some extent compensate for inefficient or damaged components (Bates, 1994), and the middle-ground lateralization position (Thal et al., 1991) that asserts initial hemispheric specialization with the potential for reorganization.  相似文献

The five-factor conceptualization of personality has been presented as all-embracing in understanding personality and has even received authoritative recommendation for understanding early development. I raise various concerns regarding this popular model. More specifically, (a) the atheoretical nature of the five-factors, their cloudy measurement, and their inappropriateness for studying early childhood are discussed; (b) the method (and morass) of factor analysis as the exclusive paradigm for conceptualizing personality is questioned and the continuing nonconsensual understandings of the five-factors is noted; (c) various unrecognized but successful efforts to specify aspects of character not subsumed by the catholic five-factors are brought forward; and (d) transformational developments in regard to inventory assessment of personality are mentioned. I conclude by suggesting that repeatedly observed higher order factors hierarchically above the proclaimed five may promise deeper biological understanding of the origins and implications of these superfactors.  相似文献

Social support represents an important recovery factor for individuals with posttraumatic stress disorder (PTSD). Nevertheless, partners, family, and friends who take on the role of caregiver for individuals with PTSD might face multiple difficulties. For example, they are at risk for developing anxiety and depressive symptoms, which could negatively affect their ability to offer support. This study examined the associations between the difficulties of individuals with PTSD (i.e., symptoms and level of functioning), their caregivers’ (partners, family, and friends) anxiety and depressive symptoms, and social support behaviors according to 2 variables: relationship status and gender. Sixty-five individuals with PTSD and either their partner, family member, or friend filled out questionnaires and participated in a trauma-oriented discussion. Social support behaviors were coded. Results revealed no associations between the difficulties of individuals with PTSD and their caregivers’ symptoms. However, caregivers’ depressive symptoms were negatively associated with the quality of some of their social support behaviors. Moreover, relationship status and gender were significant moderators, indicating stronger negative associations between anxiety and depressive symptoms and some social support behaviors of men and caregiving partners. Male caregivers could have difficulties offering appropriate support and responding to traditional masculine roles (e.g., being strong and self-reliant) when they report symptoms themselves. Partners are particularly involved in the everyday life of individuals with PTSD. Thus, they could have difficulties keeping an optimal emotional distance to offer support when they report symptoms themselves. Future directions as well as clinical implications are discussed.  相似文献

We examined how valence and arousal of an image influence visual attention. “Spotlight of attention” theory suggests that positive affect broadens, and negative affect narrows, one's aperture of attention, whereas the arousal theory literature suggests that arousal level is what modulates attentional focus, with highly arousing affect capturing attention, regardless of valence. In two experiments, a digit parity task was used to index the influence of valence, and arousal, on visual attention. Positive or negative images were displayed centrally on each trial, with single digits presented more peripherally (Experiment 1) or more centrally (Experiment 2) to the image. In both Experiments participants were slower, and less accurate at making parity decisions (e.g., both digits odd or both even) when the image was negative relative to positive, and of high arousal. For low arousal images, positive, relative to negative, valence images led to greater impairment of the digit parity task. Findings suggest that arousal level of images modulates the influence of valence on distribution of visual attention. Highly negative emotional images may command or capture attention, but there are other factors that can lead to attention capture, even in low arousing positive stimuli.  相似文献

ABSTRACT

We examined how context presented at study affects recollection of words in younger and older adults. In Experiment 1, participants studied words presented with a picture of a face (context-rich condition) or a rectangle (context-weak condition), and subsequently made ‘Remember’, ‘Know’, or ‘New’ judgments to words presented alone. Younger, but not older, adults showed higher Remember accuracy following rich- than weak-context trials. In Experiment 2, we manipulated the type of processing engaged during the encoding of context–word pairs. Younger and older adults studied words presented with a picture of a face under a surface feature (gender) or binding feature (match) instruction condition. Both age groups showed higher Remember accuracy in the binding than surface instruction condition. Results suggest that providing rich contextual detail at encoding boosts later item recollection in younger adults. Older adults, however, do not spontaneously engage in the processes required to boost recollection, though instructional manipulation during encoding lessens this deficit.  相似文献

Evaluates the the act frequency approach (AFA), noting that retrospective self-reports rather than behavioral acts are studied; act context and meaning are not considered; the AFA self-report inventories are incompletely developed and are psychometrically unsound; the AFA claim of absolute measurement of dispositions is insupportable; many of the self-report act statements used are technically unacceptable or conceptually unwarranted; the research agenda of the AFA primarily involves only "internal analyses" of self-report "act" inventories and indices and proposes the further creation of "act" inventories to index thousands of conceptually unorderable dispositions. Were the problems involved in the current implementation of the AFA to be resolved, various large conceptual problems presently besetting the approach then would have to be confronted.  相似文献

Unilateral nostril breathing influences lateralized cognitive performance   总被引:1,自引:0,他引:1  
Relative nostril efficiency (nasal cycle) is related to hemispheric EEG differences and performance on cognitive tasks. We investigated how unilateral forced nostril breathing influences spatial and verbal performance. Right-handed males and females performed both tasks under either left-nostril, right-nostril, or free-breathing conditions. Unilateral breathing affects performance differently in males and females. It influences male performance ipsilaterally on both tasks: Their spatial performance is better during right-nostril breathing, and their verbal performance is better during left-nostril breathing. Unilateral breathing influences female performance contralaterally, but only on the spatial task: Their spatial performance is better during left-nostril breathing. These differences within and between sexes may exist because unilateral nostril breathing differentially activates the two hemispheres and thereby facilitates performance, or because attempts of the brain to control the nasal cycle unilaterally interfere with performance.  相似文献

Sex differences in proneness to depression and paranoia are seen as reflecting caricatures of women s and men's stereotypical role in a male-dominated, exploitative society Following its major hypothesis that mental illness arises out of failures in the sociability that is inherent in our species, the paper discusses some of the evidence for sex differences in sociability, and some evidence from studies of sex differences in field dependence which, taken together, suggest a sex difference in proneness to shame and guilt This sex difference in ‘superego” style is a mediating factor in proneness to depression and paranoia  相似文献
