Studies suggest motor deficit asymmetry may help predict the pattern of cognitive impairment in individuals with Parkinson disease (PD). We tested this hypothesis using a highly validated and sensitive spatial memory task, spatial delayed response (SDR), and clinical and neuroimaging measures of PD asymmetry. We predicted SDR performance would be more impaired by PD-related changes in the right side of the brain than in the left. PD (n = 35) and control (n = 28) participants performed the SDR task. PD participants either had worse motor deficits on the right (RPD) or left (LPD) side of the body. Some participants also had magnetic resonance imaging for measurement of their substantia nigra (SN) volumes. The LPD group performed worse on the SDR task than the RPD and control groups. Right SN volume accounted for a unique and significant portion of the variance in SDR error, with smaller volume predicting poorer performance. In conclusion, left motor dysfunction and smaller right SN volume are associated with poorer spatial memory. 相似文献

Prospective and positive mental imagery deficits in dysphoria 总被引:1,自引:0,他引:1
We know less about positive mental imagery than we do about negative mental imagery in depression. This study examined the relationship between depressed mood and the subjective experience of emotion in imagined events; specifically, prospective imagery, and imagery in response to emotionally ambiguous stimuli. One hundred and twenty-six undergraduates completed measures of depression, imagery vividness for future events, and a homograph interpretation task in which they generated images and subsequently rated image pleasantness and vividness. As predicted, compared to low dysphoria, high dysphoria was associated with poorer ability to vividly imagine positive (but not negative) future events. These findings were augmented by the observation that high dysphorics provided lower pleasantness ratings of images generated in response to homographs they interpreted as positive. We suggest that an imbalance in the inability to vividly imagine positive but not negative future events may curtail the ability of high dysphorics to be optimistic. High dysphoric individuals are further disadvantaged: even when they interpret ambiguity positively, the resulting images they generate are associated with less positive affect. Therapeutic strategies that address both such positive-specific imagery biases hold promise for depression treatment innovation. 相似文献

Premarital precursors of infidelity were evaluated in a sample of 72 couples (N = 144) who were taking part in a longitudinal study of marriage. Premarital self-report and observational data were compared for couples who experienced infidelity and those who did not experience infidelity in the first years of marriage. Couples in which the male engaged in marital infidelity were characterized, premaritally, by significantly lower male sexual satisfaction, lower male positive communication, and higher female invalidation, whereas couples in which the female went on to engage in infidelity were characterized, premaritally, by significantly lower levels of female positive communication, higher levels of male and female negative communication, and higher levels of male and female invalidation. Implications of the findings for future research on the prediction and prevention of infidelity are discussed. 相似文献

The present study examined prevalence of lack of a close confidant in a medically underserved primary care sample, and evaluated demographic, medical, and psychological correlates of patients' deficits in close, personal contact. Adult patients (n = 413) reported on confidant status and symptoms of depression and anxiety. Sociodemographic and medical information were obtained through chart review. One-quarter of patients endorsed lack of a close confidant. Past month anxiety and depression symptoms, but not medical status, were associated with unmet socioemotional needs. Implications for primary healthcare interventions are discussed. 相似文献

The present work investigated the effect of modelling on children's pretend play behaviour. Thirty‐seven children aged between 27 and 41 months were given 4 min of free play with a dollhouse and associated toy props (pre‐modelling phase). Using dolls, an experimenter then acted out a series of vignettes involving object substitutions, imaginary play and attribution of properties. Children were subsequently provided with an additional 4 min free play (post‐modelling phase). Consistent with past research, more pretence was exhibited after modelling than before. Furthermore, in the post‐modelling phase, children were as likely to generate their own novel pretence as they were to copy the actions demonstrated by the experimenter. They also increased the number of novel symbolic acts involving imaginary play from the pre‐ to the post‐modelling phase. This study highlights how young children will not only imitate a model's demonstration of pretend acts but also use this demonstration to catalyze the creation of their own pretence.

The present investigation examined the relationships between five demographic variables (age, sex, income, marital status,
and education) and future time perspective. From a theoretical perspective, these demographic indicators were conceptualized
as proxy measures for the social forces that influence the adult expression of this personality dimension. Data were drawn
from six investigations in which a brief measure of future time perspective (Hershey and Mowen in The Gerontologist 40:687–697,
2000) had been administered to one thousand four hundred and ninety eight individuals. Higher future time perspective scores
(i.e., longer future orientations) were associated with being male, increased age, income, and educational level. These main
effects, however, were mitigated by a significant three-way interaction among sex, age, and level of education. These findings
suggest that a complex interplay of variables is responsible for the expression of personality traits at the individual level. 相似文献

Psychological Foundations of Financial Planning for Retirement 总被引:1,自引:0,他引:1

Little is known about the psychological mechanisms that underlie financial planning for retirement. Most studies of financial planning and investing have used demographic indicators (e.g., age, gender, income) to predict individual differences in saving. In the present study, a model of planning is tested in which psychological indicators (future time perspective, retirement goal clarity, and self-rated financial knowledge) are posited to mediate the relationship between demographic indicators and saving behaviors. Path-analytic techniques were used to test the model, based on data from 265 middle-aged working adults. Analyses revealed substantial support for the role of psychological factors in the retirement planning process. Findings have theoretical implications for the development of psychologically based models of planning, as well as applied implications for those who seek to understand the psychomotivational forces that underlie tendencies to plan and save. 相似文献

Previous researchers (e.g., J. A. Bargh, 1992, 2002) demonstrated the importance of nonconscious processes on consumer choice behavior. Using an advertisement, the authors determined the effect of two nonconscious processes--the mere exposure effect, which increases object preference by increasing consumer exposure to an object, and the endowment effect, which increases object valuation by providing consumer possession of an object--on consumer behavior. Although the mere exposure effect and endowment effect did not produce an interaction, they produced independent effects. The endowment effect increased object valuation but not object preference. The mere exposure effect increased object preference but not object valuation. Thus, at the unconscious level, an increase in object preference does not lead to an increase in object valuation, nor does an increase in object valuation lead to an increase in object preference. The authors discuss the importance of developing measures of unconscious process in advertising effectiveness. 相似文献
