The purpose of this study was to test a model based on Social Cognitive Career Theory (Lent, Brown, & Hackett, 1994) that placed perceived social status as an antecedent of career-related learning experiences, self-efficacy, and outcome expectations. Gender was included in the present model and results indicated that gender related as expected to differential exposure to career-related learning experiences in Holland's (1997) RIASEC domains. After controlling for the effects of gender, results demonstrated that perceived social status related positively to learning experiences in the Investigative, Enterprising, and Conventional areas among 380 college students. Further, these enhanced learning experiences mediated the relationships between perceived social status and self-efficacy, and between perceived social status and outcome expectations, for the Investigative, Enterprising, and Conventional areas. These findings highlight the importance of perceived social status as a predictor of exposure to different types of career-related learning experiences that subsequently shape students' self-efficacy, outcome expectations, and (presumably) interests in particular RIASEC areas. Results are discussed in terms of exposure to career-related learning experiences in RIASEC domains with differing levels of prestige and implications of these results for developing interventions to enhance the learning experiences of students who report lower levels of perceived social status are presented. 相似文献
Retrieval-induced forgetting (RIF) is a widely studied phenomenon of human memory, but RIF of arithmetic facts remains relatively unexplored. In 2 experiments, we investigated RIF of simple addition facts (2 + 3 = 5) from practice of their multiplication counterparts (2 × 3 = 6). In both experiments, robust RIF expressed in response times occurred only for high-strength small-number addition facts with sums ≤ 10, indicating that RIF from multiplication practice was interference dependent. RIF of addition-fact memory was produced by multiplication retrieval (2 × 3 = ?) but not multiplication study (2 × 3 = 6), supporting an inhibitory mechanism of RIF in arithmetic memory. Finally, RIF occurred with multiplication practiced in word format (three × four) and addition tested later in digit format (3 + 4), which provides evidence that digit and written-word formats for arithmetic accessed a common semantic retrieval network. The results support the view that addition and multiplication facts are stored in an interrelated semantic network and that RIF of competing addition facts is an intrinsic process of multiplication fact retrieval. 相似文献
Monkeys, unlike chimpanzees and humans, have a marked difficulty acquiring relational matching-to-sample (RMTS) tasks that likely reflect the cognitive foundation upon which analogical reasoning rests. In the present study, rhesus monkeys (Macaca mulatta) completed a categorical (identity and nonidentity) RMTS task with differential reward (pellet ratio) and/or punishment (timeout ratio) outcomes for correct and incorrect choices. Monkeys in either differential reward-only or punishment-only conditions performed at chance levels. However, the RMTS performance of monkeys experiencing both differential reward and punishment conditions was significantly better than chance. Subsequently when all animals experienced nondifferential outcomes tests, their RMTS performance levels were at chance. These results indicate that combining differential reward and punishment contingencies provide an effective, albeit transitory, scaffolding for monkeys to judge analogical relations-between-relations. 相似文献
Several studies have used a visual search task to demonstrate that schematic negative-face targets are found faster and/or more efficiently than positive ones, with these findings taken as evidence that negative emotional expression is capable of guiding attentional allocation in visual search. A common hypothesis is that these effects should be disrupted by face inversion; however, this has not been consistently demonstrated, and raises the possibility of a perceptual confound. One candidate confound is the feature of "closure" (see Wolfe & Horowitz, 2004) caused by the down-turned mouth adjacent to edge of the face. This was investigated in the present series of experiments. In Experiment 1, the speed advantage for upright negative faces was replicated. In Experiment 2, the effect was not disrupted with inversion, and an efficiency advantage emerged, suggesting that perceptual features could be causing the advantage. In Experiment 3, speed and efficiency effects were seen when this perceptual characteristic remained but face features were scrambled. Taken together, these findings suggest that visual search using schematic faces containing a curved-line mouth feature cannot provide a valid test of guided search by negative facial emotion unless this confound is controlled. 相似文献
High productivity by behavioral health consultants (BHC) is a defining aspect of the primary care behavioral health (PCBH) model to maximize access to care and is often measured by patient volume. Studies of productivity in health care settings suggest a single productivity target may not be optimal. We used a Delphi method to obtain expert consensus on an operational definition of high productivity by BHCs in the PCBH model. Clinicians, managers, and researchers in PCBH were recruited to participate in a multi-round survey using a modified Delphi technique and develop consensus on PCBH productivity metrics. Ten participants completed all three survey rounds and rated 28 metrics. After three rounds, two direct metrics (average number of billable BHC visits each day; number of patients seen per day) received at least 80% consensus as “Essential”, two received at least 50%, and five received less than 50%. One influencer (level of integration at the practice) received at least 80% consensus as “Very Much” influential, 19 received at least 50%, and eight items received less than 50%. Several themes arose from participant comments. PCBH productivity can be interpreted as being high volume. Numerous practice factors influence how productive a BHC may be. Future studies should determine the feasibility of our metrics in clinical practice, establish productivity expectations based on patient needs and clinic resources, and identify patient-, clinician-, or practice-level moderators of productivity.
Recent insights show that increased motivation can benefit executive control, but this effect has not been explored in relation to semantic cognition. Patients with deficits of controlled semantic retrieval in the context of semantic aphasia (SA) after stroke may benefit from this approach since ‘semantic control’ is considered an executive process. Deficits in this domain are partially distinct from the domain-general deficits of cognitive control. We assessed the effect of both extrinsic and intrinsic motivation in healthy controls and SA patients. Experiment 1 manipulated extrinsic reward using high or low levels of points for correct responses during a semantic association task. Experiment 2 manipulated the intrinsic value of items using self-reference, allocating pictures of items to the participant (‘self’) or researcher (‘other’) in a shopping game before participants retrieved their semantic associations. These experiments revealed that patients, but not controls, showed better performance when given an extrinsic reward, consistent with the view that increased external motivation may help ameliorate patients’ semantic control deficits. However, while self-reference was associated with better episodic memory, there was no effect on semantic retrieval. We conclude that semantic control deficits can be reduced when extrinsic rewards are anticipated; this enhanced motivational state is expected to support proactive control, for example, through the maintenance of task representations. It may be possible to harness this modulatory impact of reward to combat the control demands of semantic tasks in SA patients. 相似文献
African Americans are overrepresented on the organ transplant waiting list and underrepresented among organ and tissue donors. One of the most highly noted reasons for lack of donation is the perception that donation is contrary to religious beliefs. The purpose of this cross-sectional study is to explore the complexities of religion (beliefs, religiosity, and religious involvement) and its association with willingness to donate and the written expression of donation intentions. Findings from a sample of 505 African American participants suggest that religion is a multidimensional construct and results differ depending on how the construct is measured and operationalized. 相似文献
