Drug craving has purportedly been linked to relapse and to substance use. For over two decades, cue reactivity has been a viable method to assess craving and physiological reactions to drug stimuli. However, traditional cue reactivity has faced the following limitations: austere situations or stimuli, lack of complex cues, lack of standardization, and limited generalization outside of the lab setting. In order to improve cue methodologies, a virtual reality (VR) nicotine cue reactivity assessment system (VR-NCRAS) was developed and tested in a controlled experimental trial. Ten nicotine dependent smokers were exposed to VR smoking cues and VR neutral cues in a standardized, timed, computer controlled experiment. Subjective craving and physiological responses were recorded and compared across VR-NCRAS stimuli. Subjective cigarette craving increased significantly and corresponding physiological reactivity was observed in response to VR smoking cues. VR neutral cues did not result in subjective or physiological changes consistent with craving. Implications of these findings on substance abuse research and treatment are discussed. 相似文献

Children without formal education in addition and subtraction are able to perform multi-step operations over an approximate number of objects. Further, their performance improves when solving approximate (but not exact) addition and subtraction problems that allow for inversion as a shortcut (e.g., a?+?b???b?=?a). The current study examines children's ability to perform multi-step operations, and the potential for an inversion benefit, for the operations of approximate, non-symbolic multiplication and division. Children were trained to compute a multiplication and division scaling factor (*2 or /2, *4 or /4), and were then tested on problems that combined two of these factors in a way that either allowed for an inversion shortcut (e.g., 8*4/4) or did not (e.g., 8*4/2). Children's performance was significantly better than chance for all scaling factors during training, and they successfully computed the outcomes of the multi-step testing problems. They did not exhibit a performance benefit for problems with the a*b/b structure, suggesting that they did not draw upon inversion reasoning as a logical shortcut to help them solve the multi-step test problems. 相似文献

Although the development of number-line estimation ability is well documented, little is known of the processes underlying
successful estimators’ mappings of numerical information onto spatial representations during these tasks. We tracked adults’
eye movements during a number-line estimation task to investigate the processes underlying number-to-space translation, with
three main results. First, eye movements were strongly related to the target number’s location, and early processing measures
directly predicted later estimation performance. Second, fixations and estimates were influenced by the size of the first
number presented, indicating that adults calibrate their estimates online. Third, adults’ number-line estimates demonstrated
patterns of error consistent with the predictions of psychophysical models of proportion estimation, and eye movement data
predicted the specific error patterns we observed. These results support proportion-based accounts of number-line estimation
and suggest that adults’ translation of numerical information into spatial representations is a rapid, online process. 相似文献

Adults vary their haptic exploratory behavior reliably with variation both in the sensory input and in the task goals. Little is known about the development of these connections between perceptual goals and exploratory behaviors. A total of 36 children ages 3, 4, and 5 years and 20 adults completed a haptic intramodal match-to-sample task. Participants were instructed to feel the shape, texture, rigidity, or weight of a sample object and then were asked to find which of three test objects matched the sample on that specific property. Hand movements were examined to determine whether children produced the same exploratory procedures while gathering perceptual information about each property as adults who searched for the same kind of information. Children demonstrated that they had good haptic abilities in two ways: They matched the sample objects on the specified perceptual dimension at near ceiling levels, and they produced the same hand movement patterns to find the same properties as adults. 相似文献

Transcendence Matters: Do the Ways Family Members Experience God Meaningfully Relate to Family Life?
As more Americans continue to move away from an institutional approach to religion and spirituality to a more personal approach, it is important to explore the ways that personal perspectives about God influence various aspects of life including family life. This study explored how participants viewed and experienced God as an authority figure (Directive Transcendence), as a close confidant (Intimate Transcendence), or as both (Authoritative Transcendence). In-depth interviews with 198 religious families from across America were analyzed using a team-based qualitative approach. These analyses revealed that participants experienced God as both an authority figure and as a close confidant. Both types of experiences are associated with family relationships in different ways. Concepts relating to ideas of authority, parenting styles, and attachment theory are used to help understand familial impacts from how one experiences God. 相似文献

Recent developmental research demonstrates that group bias emerges early in childhood. However, little is known about the extent to which bias in minimal (i.e., arbitrarily assigned) groups varies with children's environment and experience, and whether such bias is universal across cultures. In this study, the development of group bias was investigated using a minimal groups paradigm with 46 four- to six-year-olds from the Faroe Islands. Children observed in-group and out-group members exhibiting varying degrees of prosocial behaviour (egalitarian or stingy sharing). Children did not prefer their in-group in the pretest, but a pro-in-group and anti-out-group sentiment emerged in both conditions in the posttest. Faroese children's response patterns differ from those of American children [Schug, M. G., Shusterman, A., Barth, H., & Patalano, A. L. (2013). Minimal-group membership influences children's responses to novel experience with group members. Developmental Science, 16(1), 47–55], suggesting that intergroup bias shows cultural variation even in a minimal groups context. 相似文献

Several decades of laboratory research have shown that high-dominant women, when paired with low-dominant men, are less likely than expected to emerge as leaders on gender-neutral tasks. The current study was designed to investigate the impact of an incentive on leadership emergence in mixed-gender pairs in which one member was high in personality dominance and one was low. Across incentive conditions, men high in personality dominance were more likely than women to emerge as leaders. Under the no-incentive condition, personality dominance relative to men did not significantly improve women’s leadership likelihood; men were more likely to emerge as leaders regardless of personality dominance. However, under the incentive condition, high-dominant women were significantly more likely to emerge as leaders than were their low-dominant male counterparts, and high-dominant men were also more likely than low-dominant women to emerge as leaders. 相似文献
