Factor analytic studies of the 24-item Personal Attributes Questionnaire (Spence & Helmreich, 1978) have reported inconsistent results, and a previous confirmatory factor analysis (CFA) indicated inadequate fit for factors corresponding to Masculinity, Femininity, and Masculinity-Femininity scales. In this research, we used CFA in a college sample (N = 382) to evaluate the 3-factor model, and we revised scales by eliminating 6 misspecified items. The revised model fit well in another college sample (N = 230). We renamed the revised scales Agency, Communion, and Emotional Vulnerability. In relation to Five-factor theory, Emotional Vulnerability and Communion correlated well with Neuroticism and Agreeableness, respectively, and Agency had moderate correlations with Neuroticism, Extraversion, and Conscientiousness. Psychometric results in the context of current theory suggest that Agency (Masculinity) may not be a fully adequate measure of the agency construct.  相似文献

In 3 experiments, participants saw lists of 16 words for free recall with or without a 6-digit immediate serial recall (ISR) task after each word. Free recall was performed under standard visual silent and spoken-aloud conditions (Experiment 1), overt rehearsal conditions (Experiment 2), and fixed rehearsal conditions (Experiment 3). The authors found that in each experiment, there was no effect of ISR on the magnitude of the recency effect, but interleaved ISR disrupted free recall of those words that would otherwise be rehearsed. The authors conclude that ISR and recency cannot both be outputs from a unitary limited-capacity short-term memory store and discuss the possibility that the process of rehearsal may be common to both tasks.  相似文献

Following a pretest, 8 participants who were unfamiliar with algebraic and trigonometric functions received a brief presentation on the rectangular coordinate system. Next, they participated in a computer-interactive matching-to-sample procedure that trained formula-to-formula and formula-to-graph relations. Then, they were exposed to 40 novel formula-to-graph tests and 10 novel graph-to-formula tests. Seven of the 8 participants showed substantial improvement in identifying formula-to-graph relations; however, in the test of novel graph-to-formula relations, participants tended to select equations in their factored form. Next, we manipulated contextual cues in the form of rules regarding mathematical preferences. First, we informed participants that standard forms of equations were preferred over factored forms. In a subsequent test of 10 additional novel graph-to-formula relations, participants shifted their selections to favor equations in their standard form. This preference reversed during 10 more tests when financial reward was made contingent on correct identification of formulas in factored form. Formula preferences and transformation of novel mathematical and stimulus functions are discussed.  相似文献

Four experiments investigated item and order memory for sequences of seen unfamiliar faces and heard nonwords. Experiments 1 and 3 found bowed serial position curves using the serial reconstruction test of order with faces and nonwords, respectively. Experiments 2 and 4 found limited recency, no primacy, and above chance performance on all items using a two‐alternative forced choice (2AFC) test of item recognition, again with faces and nonwords. These results suggest that the different serial position curves typically found using traditional paradigms for exploring visual and verbal short‐term memory are due to differences in the methods used rather than modality‐specific mechanisms.  相似文献

This study investigated the development of prospective memory using tasks based on the prefrontal-lobe model. Three groups each of 30 children, adolescents, and young adults were compared on prospective-memory performance using ongoing tasks with two levels of cognitive demand (low and high), and two levels of importance (unstressed and stressed) of remembering prospective cues. The Self-Ordered Pointing Task (SOPT), Stroop Color Word Interference Test, and Tower of London were also used to assess relationships between prospective memory and prefrontal-lobe functions. The children remembered fewer prospective cues than either the adolescents or adults, but the adolescents and adults remembered equally well. This trend increased significantly as the cognitive demand of the ongoing tasks increased. However, stressing or not stressing the importance of remembering made no difference to prospective-memory performance. Performance on the SOPT and Stroop Colour Word Interference predicted performance on the high- but not on the low-demand condition. These findings implicate the maturation of the brain's prefrontal region in the development of prospective memory.  相似文献

A reliable two-factor instrument measuring appearance motivation attitudes for sun protection was developed using a longitudinal sample of beachgoers. At baseline, data on sun protection and appearance motivation attitudes were collected on 2324 individuals. Principal components analyses (PCA) indicated a two-factor solution measuring attitudes toward tan attractiveness and skin protection with only 2 items loading on the skin protection factor. At 12-months, the instrument was revised and shortened but including 3 new skin protection items. Split-half analyses were conducted to further refine and develop the instrument. PCA on half of the sample revealed a two-factor solution, which was confirmed using structural equation modeling on the remaining half. This resulted in a two correlated-factor, 10-item measure. Each factor was summed to create two scales. Both scales were internally consistent and demonstrated good external validity, correlating with sun protection specific Transtheoretical model variables. The tan attractiveness attitudes scale significantly improved prediction of sun protection outcomes over 24 months, over and above TTM variables.  相似文献

Abstract

Recent investigations suggest that the hostility component of the Type A behavior patter (TABP) is a greater detriment to health than the overall pattern. Some researchers suggest that certain Type A characteristics (e.g., job-involvement) are actually adaptive. This study compared the relative relationship of the TABP and hostility to career-related achievement and psychosocial adjustment among 223 service-delivery employees. Male and female participants completed the Jenkins Activity Survey and the MMPI Hostility Scale as part of a cardiovascular disease risk factor screening. The TABP was positively associated with managerial status for both men and women. However, the TABP was positively related to psychosocial adjustment variables among men only. Hostility was significantly related to undesirable outcomes including lower job status, life dissatisfaction, and unfavorable perceptions of the workplace for both men and women. Discussion addresses organizational factors which might perpetuate hostility and the TABP, as well as gender differences in the experience of these constructs.  相似文献

This study aimed to explore the lived experience of assuming the primary caregiver role in a group of spouses of individuals living with a traumatic spinal cord injury (SCI) (injuries ranged from paraplegia to quadriplegia). Individual in-depth interviews were conducted with 11 participants who were both the spouse and primary caregiver of an individual with a SCI; of these, 10 were female and 1 was male. All interviews were transcribed verbatim and were subjected to interpretative phenomenological analysis (IPA). Here we present three inter-related master themes: ‘The emotional impact of SCI’; ‘Post-injury shift in relationship dynamics’ and ‘Impact of caregiving on identity’. Regarding the emotional impact of spinal injury, participants reported an almost instantaneous sense of loss, emptiness and grief during the injured person's rehabilitative period and feelings of anxiety were reported in anticipation of their return to the family home. A distinct change in role from spouse and lover to care provider was reported and this ultimately contributed to relationship change and a loss of former identity. The findings are discussed in relation to extant caregiver literature and recommendations for future caregiver support are highlighted.  相似文献

Because Latinos are underrepresented and often negatively stereotyped in the media, concern is frequently expressed that repeated exposure to these portrayals may reflect poorly on Latino adolescents' self-esteem. To test this issue empirically, we conducted 2 studies examining associations between multiple dimensions of self-esteem and several forms of media use. Testing 40 Latino high school students in Study 1, we found that more frequent and more active TV viewing was associated with lower social and appearance self-esteem. Many of these general patterns were replicated in Study 2 with 115 college students and with several demographic controls. Additional analyses of possible moderators revealed more consistent negative correlations among women and among participants with a stronger Latino ethnic identity. Together, these findings provide powerful evidence of a potential link between media use and the self-conceptions of Latino youth.  相似文献
