Recent research on brain activity suggests that visual attention increases in response to emotional images. This increase is reflected in signs of greater activity, in response to different emotional visual stimuli, in parietal and parietooccipital areas in several studies employing neuroimaging techniques and event-related potentials (ERPs). In the latter case, greater parietal and parietooccipital negativities have been observed. The objective of the present study was to examine the role of a person's level of motivation towards the emotional stimulus with respect to this ERP pattern. Two groups of stimuli were presented to 60 participants: neutral or N (photographs of taps) and appetitive or A (photographs of cakes). The level of hunger was measured via a questionnaire. Recordings were taken at PO3, PO4, P7, and P8. The largest differences, as a function of appetite, were produced between 575 and 625 ms. Multiple regression analyses were carried out to study the relationship between subjects' appetite and their ERP recordings in response to A and N stimuli. There was a significant negative association between appetite and 575–625 mean amplitude in response to stimulus A at PO3 and PO4. 相似文献

According to the age differentiation hypothesis (ADH), g becomes increasingly invested in specific abilities with age: with increasing age, g should account for a decreasing proportion of the variance in any particular cognitive test. However, there is no conclusive evidence concerning this important topic. Data from the Italian, Spanish, and American standardisation samples of the WPPSI and the WISC-R were analysed in the present study for testing the ADH. No changes in the proportion of variance associated with g in the 4–16 age range were found. This pattern does not change depending on the country. Therefore, the ADH is rejected: g seems to be very stable across age, and, thus, it seems to be an equally important component of intelligence test performance from early childhood to late adolescence. 相似文献

The aim of this paper is to present a dynamic goal programming scheme. Throughout the revised literature, most of the dynamic goal programming approaches use target values on the final value of the objective functionals. In this paper, dynamic target values are assumed, so that they control not only the final values of the corresponding functionals, but their evolution along the planning period. As a result, the scalar problems are also dynamic ones, where the evolution of the deviation variables is minimized. A lexicographic dynamic goal programming algorithm is developed on these basis, and some considerations are made on the efficiency of the final solutions. © 1998 John Wiley & Sons, Ltd. 相似文献

Latina/o college students (N = 120) provided their perceptions of positive psychology, cultural, family, and vocational outcome expectations. Presence of meaning in life, hope, Anglo orientation, and Mexican orientation were significant predictors of subjective happiness. Implications for counselors are provided. 相似文献

This research examines others’ perception of the influence of managers working in successful or unsuccessful companies who possess or lack status (to be respected by others) and power (control of valued resources). Study 1 shows that high‐status managers were judged as more influential in the firm than their low‐status peers, regardless of the company's situation. Study 2 finds that in a context of economic uncertainty, a manager with high status and power is perceived to be more capable of affecting the firm. The effect of power seems to be secondary since when a manager has low status, having high power does not significantly benefit the influence attributed to him or her. Furthermore, dominance (assertive behavior), not warmth, mediated the relationship between status and the attributed influence. Overall, these findings confirm that status is a very potent source of social influence, status and power are distinct constructs with different effects, and dominance rather than warmth is a key personal dimension linked to successful leadership. 相似文献

Trust plays a crucial role in interpersonal relationships, including customer–company relationships, where the customer expects that a company will behave predictably in any particular situation. Companies do not always fulfill customers' expectations and thereby breach the trust relationship. To avoid negative consequences of this trust violation, companies may issue a formal apology as one possible path to regaining customer trust. In the same way, a previous social interaction, which can increase the customer's levels of oxytocin, can help to recover trust after service failures. In this study, three experiments were conducted as follows: the first manipulating a simulated social interaction with images; the second manipulating a physical social interaction, (i.e., a hug); and the third with exogenous oxytocin administration. The results showed that both physical interaction, (i.e., a hug) and simulated social interaction, (i.e., images of people interacting with each other) had a positive effect on customer trust recovery and provided support for oxytocin release as the underlying mechanism in this process. This research contributes to understanding of the link between social interactions and trust by elucidating the effects of both simulated and physical interactions on trust recovery. 相似文献
