"Personal projects," as defined by B. R. Little (1983), were elicited from 600 community residents aged 70+, representing a broad range of health and illness. Factor analysis revealed 6 types of personal projects: activities of daily living, active recreation, other-oriented activities, intellectual activities, home planning, and spiritual moral activities. Background factors and health were shown to affect the number and type of projects reported. Most indices of personal projects were associated with positive affect and valuation of life. Only 1 was associated with depression. This confirms the differential association of personal projects to positive but not negative affect. Personal projects are seen as part of an open motivational system in which social position, cognitive ability, health, and positive mental health are mutually interacting members. 相似文献

The Bechara simulated gambling task is a popular method of examining decision-making deficits exhibited by people with brain damage, psychopathology, antisocial personality, or drug abuse problems. However, performance on this task is confounded by complex interdependencies between cognitive, motivational, and response processes, making it difficult to sort out and identify the specific processes responsible for the observed behavioral deficits. The authors compare 3 competing cognitive decision models of the Bechara task in terms of their ability to explain the performance deficits observed in Huntington's disease patients as compared with healthy populations and people with Parkinson's disease. The parameters of the best fitting model are used to decompose the observed performance deficit of the Huntington patients into cognitive, motivational, and response sources. 相似文献

Childhood maltreatment has been linked to adult depressive disorders. However, few studies have examined mechanisms through which childhood maltreatment may contribute to adult depression. Thus, we examined the role of one potential mechanism of this relationship, maladaptive cognitions, in a recently traumatized sample. Participants were adult women who had been recently raped (n = 133) or physically assaulted (n = 73). We examined whether maladaptive self-and other-cognitions mediated relationships between childhood sexual, physical, and emotional abuse and current depression. Relationships between childhood sexual abuse and both current depression symptoms and diagnosis were mediated by maladaptive cognitions about self. Relationships between both childhood sexual abuse and childhood physical abuse and adult depressive symptoms were mediated by maladaptive cognitions about others. 相似文献

The Russian Jewish intellectual, Chaim Zhitlovsky (1865–1943), a leading architect of secular Jewish culture and thought, was a central figure in the progressive Jewish intelligentsia of the late nineteenth and early twentieth century. In an essay written in 1927, Yidn un Yiddishkayt (Jews and Jewishness), he sought to define the secular essence of what he calls Yiddishkayt. This essay is not the first in Zhitlovskys long publicistic career in which he searches for new, secular definitions of Jewish identity and culture. But this essay differs, since it is marked by Zhitlovskys use of contemporary social scientific notions of race and racial traits to conceptualize what he believes constitutes Jewishness in a non-religious context, along with his adoption of the mystical Jewish concept of the pintele yid, the theory of an innate Jewishness embodied by a Jewish spark. Zhitlovskys desire to craft a truly secular theory of Jewish identity led him ironically to accept models of Jewish identity at odds with his stated larger vision. In turning to contemporary racial theory, as well as long nurtured mystical models of Yiddishkayt, Zhitlovsky reveals the wide range of ideological discourses that led him to innovative and controversial notions of modern Jewish identity. 相似文献

Findings from a complex decision-making task (the Iowa gambling task) show that individuals with neuropsychological disorders are characterized by decision-making deficits that lead to maladaptive risk-taking behavior. This article describes a cognitive model that distills performance in this task into three different underlying psychological components: the relative impact of rewards and punishments on evaluations of options, the rate that the contingent payoffs are learned, and the consistency between learning and responding. Findings from 10 studies are organized by distilling the observed decision deficits into the three basic components and locating the neuropsychological disorders in this component space. The results reveal a cluster of populations characterized by making risky choices despite high attention to losses, perhaps because of difficulties in creating emotive representations. These findings demonstrate the potential contribution of cognitive models in building bridges between neuroscience and behavior. 相似文献

How do we think about the space of bodies? Several accounts of mental representations of bodies were addressed in body part verification tasks. Animagery account predicts shorter times to larger parts (e.g., back < hand). Apart distinctiveness account predicts shorter times to more discontinuous parts (e.g., arm < chest). Apart significance account predicts shorter times to parts that are perceptually distinct and functionally important (e.g., head < back). Because distinctiveness and significance are correlated, the latter two accounts are difficult to distinguish. Both name-body and body-body comparisons were investigated in four experiments. In all, larger parts were verified more slowly than smaller ones, eliminating the imagery/size account. Despite the correlation between distinctiveness and significance, the data suggest that when comparisons are perceptual (body-body), part distinctiveness is the best predictor, and when explicit or implicit naming is involved, part significance is the best predictor. Naming seems to activate the functional aspects of bodies. 相似文献

The authors investigated the psychometric properties of the Beck Anxiety Inventory (BAI) in a sample of 75 older generalized anxiety disorder (GAD) patients and a comparison group of 32 older adults without significant psychopathology. Internal consistency was above .80, and the BAI showed evidence of convergent validity in both groups. Evidence for discriminant validity with respect to measures of depression was weaker. Two items, fearing the worst and nervousness, correctly distinguished 86.5% of patients with GAD and 93.8% of the normal controls. Medical comorbidity was associated with somatic but not cognitive anxiety symptoms in the normal older sample. Overall, results indicate the limitations of the BAI in assessing anxiety symptoms in older adults and suggest the need for use of an instrument focusing on cognitive aspects of anxiety. 相似文献

We conducted two word-by-word reading experiments to investigate the timing of implausibility detection for recipient and instrument prepositional phrases (PPs). These PPs differ in thematic role, relative frequency, and possibly in argument status. The results showed a difference in the timing of garden path effects such that the detection of implausible dative recipients (which are clearly arguments) was delayed relative to the detection of implausible instruments (which may not be arguments). They also demonstrated that commitments to syntactic structure were made at the preposition for both dative and instrument PPs. While these results refute delay models of parsing (e.g., Britt, 1994) and syntax-first accounts of PP-attachment (e.g., Frazier, 1978; Frazier & Clifton, 1996), they support constraint-based lexicalist models that enable verb bias and plausibility information to compete (Garnsey, Pearlmutter, Myers, & Lotocky, 1997). 相似文献

This article examines the theoretical basis of decision-making deficits exhibited by cocaine abusers in a laboratory decision-making
task first described by Bechara, Damasio, Damasio, and Anderson (1994). A total of 12 male cocaine abusers and 14 comparison
subjects performed the task, and the cocaine group performed significantly worse than the comparison group. A cognitive modeling
analysis (Busemeyer & Stout, 2002) was used to estimate three parameters that measure importance of the cognitive, motivational,
and response processes for determining the observed performance deficit. The results of this analysis indicated, for the first
time, that motivational and choice consistency factors, but not learning/ memory were mainly responsible for the decision-making
deficit of the cocaine abusers in this task. 相似文献

These cancer genetic counseling recommendations describe the medical, psychosocial, and ethical ramifications of identifying at-risk individuals through cancer risk assessment with or without genetic testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors Cancer Genetic Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment and counseling as well as the personal expertise of genetic counselors specializing in cancer genetics. The recommendations are intended to provide information about the process of genetic counseling and risk assessment for hereditary cancer disorders rather than specific information about individual syndromes. Key components include the intake (medical and family histories), psychosocial assessment (assessment of risk perception), cancer risk assessment (determination and communication of risk), molecular testing for hereditary cancer syndromes (regulations, informed consent, and counseling process), and follow-up considerations. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider's professional judgment based on the clinical circumstances of a client. 相似文献
