We performed two experiments comparing the effects of speech production and speech comprehension on simulated driving performance. In both experiments, participants completed a speech task and a simulated driving task under single‐ and dual‐task conditions, with language materials matched for linguistic complexity. In Experiment 1, concurrent production and comprehension resulted in more variable velocity compared to driving alone. Experiment 2 replicated these effects in a more difficult simulated driving environment, with participants showing larger and more variable headway times when speaking or listening while driving than when just driving. In both experiments, concurrent production yielded better control of lane position relative to single‐task performance; concurrent comprehension had little impact on control of lane position. On all other measures, production and comprehension had very similar effects on driving. The results show, in line with previous work, that there are detrimental consequences for driving of concurrent language use. Our findings imply that these detrimental consequences may be roughly the same whether drivers are producing speech or comprehending it. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Donor‐conceived (DC) people represent a unique population with atypical family structures. This study examined whether individual differences in attachment predict adults' self‐reported curiosity about their donor conception identity, as well as attempts to find the donor and establish contact. Data were collected from 488 DC people from the Donor Sibling Registry (DSR). People who were high in attachment‐related anxiety were more curious than others about their donor conception. Despite this curiosity, however, highly anxious people were more disengaged from donor conception and were not more likely than others to search for or have made contact with their donor. These findings suggest that insecure attachment—particularly attachment anxiety—may contribute to people's willingness to incorporate donor conception into their identities. 相似文献

Objective: A qualitative study of PwMS who had clinically significant levels of anxiety was conducted to gain a richer perspective on their experience. The objective was to explore PwMS’ experiences of anxiety and their perspectives on causes and outcomes. Design: Twenty in-depth, semi-structured interviews were conducted with PwMS consecutively recruited from the Neurology Department of a NHS University Hospital. Sixteen had a relapsing-remitting course, three had a secondary progressive course and one person had primary progressive multiple sclerosis (MS). Interviews were recorded, transcribed and analysed using inductive thematic analysis. Results: Although participants thought different factors had initially triggered their anxiety, being given the diagnosis of MS appeared to be the most significant factor for many participants. Difficulties in the workplace and in relationships, particularly related to perceived dependence on others were also important themes. A wide range of emotional responses and negative thinking patterns were associated with anxiety; this suggested the presence of comorbid depression. Participants were able to acknowledge the positive and negative coping strategies that impacted on their anxiety. Conclusion: This review confirms that anxiety can have many negative implications for PwMS and suggests that early detection and intervention are necessary in order to improve patient’s well-being. 相似文献

The authors describe a transient phase during training on a movement sequence wherein, after an initial improvement in speed and decrease in variability, individual participants' performance showed a significant increase in variability without change in mean performance speed. Subsequent to this phase, as practice continued, variability again decreased, performance significantly exceeded the gains predicted by extrapolation of the initial learning curve, the type of errors committed changed, and performance became more coherent. The transient phase of increased variability may reflect a mixture of 2 (or more) performance routines before the more effective one is set and mastered, presumably the setting up of a sequence-specific representation. Both group and individual analyses indicated a departure from the single process (e.g., power-law) model of learning. However, although similar phases appeared in the mean group data, there was little correspondence to individual participants' time courses, and the individuals' gains in the second low-variability phase were masked. 相似文献

Frontotemporal lobar degeneration (FTLD) represent a constellation of disorders that may be overlooked or misdiagnosed, despite
being fairly common presenile neurodegenerative diseases. Although the cognitive disorder can be difficult to document, particularly
early in the dementia course, neuropsychological evaluation can assist in the diagnosis. Neuropsychologists are in an excellent
position to draw from related disciplines like personality theory and social psychology to better assess the types of changes
that characterize the prodromal and early phases of the disease. This review summarizes the current state of the field in
the diagnosis of FTLD and discusses the emerging role of neuropsychology in elucidating the brain organization of complex
processes including empathy, behavioral control and inhibition, reward systems, appetitive behaviors, emotional regulation,
and goal-orientation. As this review underscores, frontotemporal dementia remains a powerful model for studying brain–behavior
relationships. 相似文献

Expert video game players often outperform non-players on measures of basic attention and performance. Such differences might result from exposure to video games or they might reflect other group differences between those people who do or do not play video games. Recent research has suggested a causal relationship between playing action video games and improvements in a variety of visual and attentional skills (e.g., [Green, C. S., & Bavelier, D. (2003). Action video game modifies visual selective attention. Nature, 423, 534-537]). The current research sought to replicate and extend these results by examining both expert/non-gamer differences and the effects of video game playing on tasks tapping a wider range of cognitive abilities, including attention, memory, and executive control. Non-gamers played 20+ h of an action video game, a puzzle game, or a real-time strategy game. Expert gamers and non-gamers differed on a number of basic cognitive skills: experts could track objects moving at greater speeds, better detected changes to objects stored in visual short-term memory, switched more quickly from one task to another, and mentally rotated objects more efficiently. Strikingly, extensive video game practice did not substantially enhance performance for non-gamers on most cognitive tasks, although they did improve somewhat in mental rotation performance. Our results suggest that at least some differences between video game experts and non-gamers in basic cognitive performance result either from far more extensive video game experience or from pre-existing group differences in abilities that result in a self-selection effect. 相似文献

Sex differences in mate preferences revisited: do people know what they initially desire in a romantic partner? 总被引:1,自引:0,他引:1
In paradigms in which participants state their ideal romantic-partner preferences or examine vignettes and photographs, men value physical attractiveness more than women do, and women value earning prospects more than men do. Yet it remains unclear if these preferences remain sex differentiated in predicting desire for real-life potential partners (i.e., individuals whom one has actually met). In the present study, the authors explored this possibility using speed dating and longitudinal follow-up procedures. Replicating previous research, participants exhibited traditional sex differences when stating the importance of physical attractiveness and earning prospects in an ideal partner and ideal speed date. However, data revealed no sex differences in the associations between participants' romantic interest in real-life potential partners (met during and outside of speed dating) and the attractiveness and earning prospects of those partners. Furthermore, participants' ideal preferences, assessed before the speed-dating event, failed to predict what inspired their actual desire at the event. Results are discussed within the context of R. E. Nisbett and T. D. Wilson's (1977) seminal article: Even regarding such a consequential aspect of mental life as romantic-partner preferences, people may lack introspective awareness of what influences their judgments and behavior. 相似文献

Is it sensible to study attachment dynamics between potential romantic partners before they share a full-fledged attachment bond? The present data indicate that such an approach may reveal novel insights about initial attraction processes. Four studies suggest that the state-like experience of attachment anxiety has functional implications within fledgling (i.e., desired or undeveloped) romantic relationships, well before the formation of an attachment bond. Studies 1 and 3 reveal that attachment anxiety directed toward a particular romantic interest is elevated before (in comparison with after) participants report being in an established relationship. Studies 2 and 3 demonstrate that such partner-specific attachment anxiety predicts attachment-relevant outcomes in fledgling relationships, including proximity seeking, safe haven, secure base, passionate love, and other approach behaviors. These associations were reliable above and beyond (and were typically as strong as or stronger than) the effect of sexual desire. Finally, Study 4 presents evidence that partner-specific attachment anxiety may cause several of these attachment-relevant outcomes. Attachment anxiety seems to be a normative experience and may signal the activation of the attachment system during the earliest stages of romantic relationships. 相似文献
