A group of 97 participants who were monolingual or bilingual and who had extensive practice playing computer video games or not completed two Simon tasks. The tasks were presented in two conditions that manipulated the number of response switches required in each block of trials. Bilingualism and video-game experience each influenced a different aspect of performance: Video-game players were faster in most conditions, including control conditions that did not include conflict from irrelevant position; bilinguals were faster only in a condition that required the most controlled attention to resolve conflict from the position and the stimulus. The results show the potential of experience to modify performance and point to subtle processing differences in various versions of the Simon task.  相似文献

The absence of significant restrictions on tobacco advertising in stores has prompted concern about the proliferation of these messages and their impact on youth. This is among the first studies to investigate the effects of adolescents’ exposure to retail tobacco advertising. Under the guise of testing teen‐interest news stories, 8th and 9th graders (n= 385) saw photographs of a convenience store that was either dominated by or devoid of tobacco advertising while listening to a story about a proposed tobacco control law or one about teen food purchases. Regardless of the news story they heard, students exposed to the tobacco‐saturated store perceived significantly easier access to cigarettes, believed more peers tried and approved of smoking, and expressed weaker support for tobacco‐control policies than did the comparison group. The study results suggest that widespread tobacco advertising in stores might distort adolescents’ perceptions about the availability, use, and popularity of this product.  相似文献

Four autoshaping experiments with pigeons examined the transfer of facilitation between drug stimuli. In Experiment 1 the presence and absence of methadone or phencyclidine signaled which of two keylight CSs were followed by grain (US). A different keylight CS was reinforced in the absence of the drugs. The drugs facilitated responding to the CS with which they were trained but did not facilitate responding to the CS reinforced in the presence of the other drug. Thus, transfer of facilitation across drug stimuli was not obtained. In Experiment 2 one of the drug facilitators was replaced by a tone. No evidence of transfer of facilitative function was obtained between the tone and the remaining drug facilitator. In Experiment 3 transfer was again not found using a design similar to that used in Experiment 1 except that the drugs did not simultaneously signal nonreinforcement of a keylight CS. In Experiment 4 the procedures of Experiment 1 were employed except that drug facilitators were replaced by distinct visual stimuli surrounding the response key. Clear evidence of transfer between the visual facilitators was obtained. The lack of transfer of modulatory control by drug stimuli in Experiments 1-3, coupled with its occurrence in Experiment 4 and previous studies, suggests that stimulus control by drugs may differ in important ways from stimulus control by conventional stimuli.  相似文献

The changing contemporary work environment has brought new career realities that suggest an altered role for the career counselor. This article reaffirms the benefits of working with the subjective aspects of career. The focus is on the intelligent career, a model that provides a framework to integrate career data into a coherent picture. The Intelligent Career Card Sort, specifically developed to elicit and work with subjective career data, is offered as a way for counselors to accommodate personal and dynamic needs of their clients beyond a job focus.  相似文献

Research indicates the presence of an age-related pictorial processing deficit, for which the elderly may attempt to compensate through the use of relational information. Cognitive asynchrony theory, a recent synthetic formulation which unites elements of the generalized slowing hypothesis, environmental support theory, and the item-specific/relational information distinction, has proven useful in a number of experiments in explaining these aspects of visual cognitive aging. The present experiments tested this theoretical formulation under high processing demand conditions in both the relational and the pictorial/item-specific realm. Young and older adults yielded a complex pattern of results consistent with the cognitive asynchrony synthesis of these theoretical considerations. The present experiments add to the growing body of findings indicating that the cognitive subsystems of memory decline at different rates, that the differences in cognitive processing between young and older adults tend to be more quantitative than qualitative, and that the global age-related memory deficits of popular belief are in fact relatively circumscribed and specific. This research was supported by grant AG11605 from the National Institute on Aging, and by a grant from the College of Science and Mathematics, California State University.  相似文献

Parents raising children adopted from a different racial/ethnic group usually engage in cultural socialization—providing activities in adoptees’ birth culture—hoping to instill pride and help adoptees develop a positive identity. Adoptive parents engage in a wide variety of socialization activities, yet adult adoptees have reported not having deep enough exposure from their parents. The present study explored the depth of cultural socialization in transracial adoptive families. Informed by Pinderhughes' Ethnic‐Racial Socialization model, this study developed a continuum examining the depth in cultural socialization with three indicators: (1) the depth of cultural activities, (2) parents’ motivation for cultural socialization, and (3) parental cultural attitudes. Qualitative analyses of 41 White parents raising children adopted from China found that parents’ motivation and acknowledgement of cultural differences reflected deep appreciation of adoptees’ birth culture, however, activities they provided were not as deep. Activities that facilitated close relationships with people who shared adoptees’ background in a natural context appeared to provide the deepest cultural connection. Despite limitations, the study demonstrated that the depth continuum was able to capture variations and nuances in cultural socialization. Suggestions for future research and recommendation for practice were also included.  相似文献

The tendency for the affect associated with positive autobiographical events to fade less over time than the affect associated with negative autobiographical events (the fading affect bias, FAB) has been observed in a variety of contexts, but numerous mediators have been reported. This current study searches for the FAB, and for potential moderators of the FAB, in the context of romantic relationship memories. Both nonsexual types of memories and sexual types of memories showed the FAB. Moreover, the FAB emerged for memories of current relationships, but not for memories of past failed relationships. The FAB also emerged for securely attached individuals, but not for individuals exhibiting other attachment styles. In addition, the FAB was moderated by relationship quality, (for failed relationships) need to belong, sexual esteem, and sexual depression. Implications of these findings both for memory and for relationships are discussed.  相似文献

To correct problems identified in existing measures of meaning in life (MIL) (lack of inclusion of items related to felt sense, mattering, and reflectivity), a new 8-item Meaning in Life Measure (MILM) was developed. Two subscales emerged: Experience (MILM-E, with items related to felt sense, mattering, goals, coherence) and Reflectivity (MILM-R, with items related to valuing thinking about meaning). High internal consistency and test–retest reliability were found for both subscales. Concurrent validity was demonstrated by a strong positive correlation between MILM-E and the Meaning in Life Questionnaire-Presence (MLQ-P), and a moderate correlation between MILM-R and the Meaning in Life Questionnaire-Search (MLQ-S). For both subscales, small to moderate positive correlations were found with subjective well-being, extraversion, conscientiousness, openness, agreeableness, self-deception, and impression management; moderate negative correlations were found with depression and emotional instability. Participants who were older, female, of higher income, and married with children scored slightly higher than their counterparts on MILM-E; women scored slightly higher than men on MILM-R. We concluded that the MILM has good psychometric properties and that MIL seems to be composed of two factors.  相似文献

Previous studies of individual differences have revealed strong correlations between children's vocabulary and grammatical abilities, and these data have been used to support theoretical accounts positing direct developmental relations between these two areas of language. However, between‐person differences do not necessarily reflect intra‐individual dynamics. Thus, in the present study, we analysed longitudinal data from three annual assessments of vocabulary and grammar in 217 children (Mage = 4 years and 3 months at first assessment) using a modelling strategy with some utility in distinguishing relations at the between‐ and within‐person levels. The results revealed strong correlations between grammar and vocabulary at the between‐person level, but the evidence of direct dependencies between the variables at the within‐person level was rather limited. Specifically, we found a small direct contribution from grammar to vocabulary for children between the ages of 4 and 5, but there was no evidence of any direct contributions from vocabulary to grammar. Further analyses suggested that the home literacy environment may represent a common source of individual differences in children's vocabulary and grammatical skills. In light of these results, we argue that the evidence of direct relations between vocabulary and grammatical development in preschool‐aged children may not be as strong as previously assumed.  相似文献
