In this study, the authors used a dual-task flanker paradigm to investigate the degree to which flankers are coprocessed with the target as a function of whether flankers have to be used as stimuli for a second task. A series of experiments, in which performance in dual tasks was compared with that in single tasks, revealed that participants had a strong tendency to coprocess flankers to a large degree in dual tasks, even if this impaired performance. Coprocessing of flankers was reduced only when totally irrelevant flankers were presented at the beginning of a trial or single tasks were performed on the great majority of trials within a block. The results suggest that it was demanding to process targets and flankers serially when both had to be used for a dual task. As a consequence, target and flankers were processed in parallel, even if this was nonoptimal for target selection. 相似文献

This study examined social network characteristics of adults aged 70 to 90 years in relation to widowhood and illness in France, Germany, Japan, and the United States. Participants were drawn from representative samples from each of the 4 countries (total N = 1,331). Resource deficit profiles based on whether respondents were widowed, ill, both, or neither were directly related to social network characteristics for German and Japanese adults, were differentially related by gender and age for French adults, and were not related to social networks of Americans. Country, gender, and age differences in total network size, proportion of close network members, and frequency of contact with network members are reported. Similarities and differences found in the associations between normative late-life deficits and social network characteristics in the 4 countries point to the importance of investigating sociocultural factors that mediate the impact of resource loss and afford life quality in very old age. 相似文献

Although a clinical case formulation can help focus treatment, little is known about the reliability and convergent validity of independently generated, cognitive–behavioral or cognitive–interpersonal formulations. Using videotapes of a semi-structured interview, pairs of clinicians independently formulated 2–3 cognitive–behavioral–interpersonal scenarios (CBISs) on each of 4 women with mood or comorbid mood and anxiety disorders. Ten licensed psychologists then rated each CBIS on 15 dimensions involving cognition, affect, symptoms, and interpersonal functioning. Reliability of the mean ratings (aggregated over the 10 raters) was >.83 for all dimensions. The set of CBISs formulated by a clinician for a patient generally demonstrated good convergent (same patient/different formulator) and discriminant (different patient/same or different formulator) validity on three factor-analytically derived general dimensions of depression, anxiety, and interpersonal functioning. Within each of three patients, pairs of formulators generally agreed on the situational components of the CBISs and demonstrated adequate to very good convergent validity of corresponding CBIS content. These results contribute to accumulating evidence for the reliability and validity of clinical scenarios as an idiographic, situation-level case formulation. Such formulations can help identify multiple cognitive, behavioral, or interpersonal intervention points in the causal chain leading to distress or dysfunction. 相似文献

Guided Search 2 (GS2) is currently one of the most detailed models of visual search and has been used to predict search times for different stimulus conditions by means of detailed computer simulations. The present article goes a step further and presents formulas that allow for the calculation of the search times and their variances. Moreover, these formulas can be applied to fit GS2 to data. An example is provided in which GS2 is fitted to search functions representing search asymmetries. 相似文献

A model is proposed and explored that links the coming-out process to the psychological functioning (i.e., self-esteem and distress) and sexual behaviors of gay, lesbian, and bisexual youths recruited from gay-focused community-based and college organizations in New York City. The coming-out process is multidimensional, consisting, as defined here, of involvement in gay/lesbian activities, attitudes toward homosexuality, comfort with homosexuality, self-disclosure of sexual identity to others, and sexual identity. The coming-out dimensions were related to self-esteem, distress, and unprotected sexual behaviors. In addition, the relations between the coming-out dimensions and unprotected sexual behaviors were explained by psychological functioning. In particular, limited involvement in gay/lesbian activities was associated with more unprotected sex. Negative attitudes toward homosexuality were related directly to more unprotected sex, and they were related indirectly to more unprotected sex by means of increasing emotional distress. These and other findings have implications for designing preventive interventions to increase the youths' psychological functioning and reduce their unprotected sexual behaviors. 相似文献

While anxiety research frequently uses only self-report measures to assess dimensions of state and trait anxiety, the present
study sought to corroborate these self-report measures using a physiological measure, namely heart rate. Another aim of the
present study was to test the multidimensional interaction model of anxiety in a social evalua-tion situation (i.e., a seminar
presentation), using a physiological measure of state anxiety. Graduate psychology students completed a state anxiety questionnaire
and were attached to a heart rate recorder prior to a class seminar presentation. One week later, students completed trait and state anxiety questionnaires and were again at-tached to a heart rate recorder
prior to seminar observation by others. Heart rate was elevated during seminar presentation relative to seminar observation, reached maxi-mum values during
the first 15 minutes of seminar presentation and then decreased over time. State anxiety scores indicate that participants
were experiencing consider-ably more anxiety just before presenting the seminar than just before observing a seminar. Heart
rate during seminar presentation was significantly correlated with self-report state anxiety and self-report social evaluation
trait anxiety, but not with seminar grade. Support was found for the multidimensional interaction model of anxiety using the
physiological measure (i.e., heart rate).

This study examined the relationship of three types of predictors of self-reported workaholism components and workaholic job behaviors: individual demographics, work situation characteristics, and two substantive workaholism antecedents (personal beliefs and fears, perceptions of organizational support of work-personal life imbalance). Data were collected from 530 women and men managers and professionals using anonymous questionnaires. The three blocks of predictors explained statistically significant but moderate levels of variance in workaholism components and workaholic job behaviors. The two substantive workaholism antecedents showed somewhat consistent relationships with the criterion measures. Participants more strongly endorsing the beliefs and fears and participants perceiving greater organizational support of work-personal life imbalance generally indicated higher levels of workaholism components and workaholic job behaviors. 相似文献
