Both alcohol and practice affect choice reaction time. The present study was conducted to investigate the possibility that impairment from alcohol and improvement with practice could be attributed to changes in the efficiency of control mechanisms (Rabbitt, 1979a), some of which depend upon the ability to judge response speed accurately. Twenty subjects participated in a four-choice reaction time experiment in which they received no alcohol (NA) in Session 1 and either no alcohol (10 subjects) or 0.8 ml alcohol (A) per kilogram of body weight (10 subjects) in Session 2. The task was to respond as fast and as accurately as possible to each stimulus. In addition, subjects were required to press a fifth key after any response that they considered to be both fast and accurate. Subjects had no difficulty in performing this task: (1) there was a significant difference of 122 msec between the mean response time for correct responses indicated as fast and that for correct responses not indicated as fast, and (2) subjects indicated 1 in 4 correct responses but only 1 in 64 errors. Alcohol increased all response times by approximately 40 msec. In contrast, practice decreased response times less for correct responses not indicated as fast than for correct responses indicated as fast. The ability to distinguish between fast and slow responses was thus unaffected by alcohol, but was improved by practice. Responses indicated as "fast" were significantly faster than errors, and appeared to occur without warning (unlike errors, which tended to end a sequence of increasingly fast correct responses). The results suggest that alcohol and practice influence choice reaction time in qualitatively different ways: Alcohol impairs overall response speed but has no effect on the ability to judge response speed, whereas practice improves both. 相似文献

Effective overall performance in judgment tasks generally involves both acquisition of information and integration of the information acquired. When information is costly the decision maker must balance acquisition costs against improved decisional accuracy, a complex balancing problem in which, laboratory evidence suggests, humans often do poorly. The three experiments reported here extend this earlier evidence to different task structures, subject pools, incentive systems, information volumes, decision aids, and kind of data sources. Though each of these factors was found to affect performance, the general finding was of persistent underpurchase (buying less information overall than is optimal) and mispurchase (buying poor sources when better sources are available at the same cost), with significant inflation of overall costs. It is proposed that unaided human judgment is unequal to the complexity of the cost/benefit trade-offs involved in acquiring costly information, and that formal decision analysis should be preferred whenever the stakes justify. 相似文献

A sample of 440 full-time employed couples from 11 states was examined to determine the differences between time spent on housework by husbands and wives in rural and urban areas. More time is spent in housework in rural families than in urban families because time spent in housework is greater for rural women than for urban women, while rural and urban husbands' times do not differ. Education of spouses, job status differentials, and age of the younger child do not significantly interact with rural-urban residence and sex of the spouse. However, family income does significantly influence the relationship between time spent on housework for rural and urban husbands and wives. 相似文献

The work of W.E.B. Du Bois highlights the significance of Christian religion in Black American life. According to Du Bois, the Black Church serves as a site of self-formation and affirmation, and the White Church as a source of racist beliefs and justifications for inequality. In this paper, we expand Du Bois’ inquiry about the influence of religion with a study of Black Americans who belong to a predominantly White religion. For those whose religious experience is almost wholly within the “white world,” what role does religion play in their lives? We analyze a set of 52 public accounts by Black Americans discussing their experiences as members of the Church of Jesus Christ of Latter-day Saints (LDS). We find that for many Black LDS, membership in the LDS Church is characterized by contrast and contradiction, yielding spiritual conviction, joy, and meaningful communion on one hand, and racism and isolation on the other. We also find that Black LDS respond to these contradictions in a variety of ways. We classify these agentic responses into five types and examine the sociological significance of the observed variation. We conclude with a discussion of implications for scholarship on race and religion. 相似文献

Realists about fictional characters posit a certain theoretical role and a candidate to fill this role. I will delineate the role realists take fictional characters like Emma Woodhouse to fill, and I will argue that it is better filled by what I will call ‘characterisations’. In explaining what I mean by ‘characterisations’, I will show that the existence of these entities is comparatively uncontroversial. Realists should acknowledge their existence, but doing so, I will argue, obviates the need to acknowledge the existence of Emma and other fictional individuals. 相似文献

We reviewed the child and the adult literature on the impact of witnesses drawing what happened on the number of details recalled and the accuracy of the reported details. Most experiments reported a beneficial effect of drawing what happened (or drawing the scene) on the number of details reported primarily in free recall and sometimes also in cued recall. The consensus across studies was that drawing protocols did not negatively impact the accuracy of reported details (when accuracy was attainable) unless suggestive details were drawn. These results were largely consistent regardless of interviewer expertise or protocol used. Draw-and-tell instructions should be considered by forensic investigators for the following reasons: (1) the beneficial effect on number of details recalled with no detriment to accuracy, (2) the added benefit for children who need additional interviewer support, and (3) the ease at which the instruction can be implemented with minimal expertise or training. However, more ecologically valid research is needed to establish the efficacy of drawing (1) in forensic interviews, (2) in the presence of misinformation, (3) across instances of repeated event memory, and (4) across sequential interviews. 相似文献

In March 2020, in response to the COVID-19 pandemic, Canadian provincial governments instituted a variety of public health measures that included social distancing and isolation, which may have had unintended consequeses. According to the Loneliness and Sexual Risk Model, gay, bisexual, and other men who have sex with men (GBM) often cope with loneliness through risky sexual behaviors. Previous studies have demonstrated that COVID-19 measures such as social distancing and isolation led to increases in loneliness; thus, these measures may also have led to elevated sexual risk-taking among some GBM. Participants were recruited from an ongoing cohort study on GBM health and well-being, and were included in the current analysis if they had completed relevant study questions (n = 1134). GBM who reported lower levels of social support pre-COVID-19, were younger, and lived alone each reported greater loneliness during the first year of COVID-19. Although feelings of loneliness did not predict sexual risk-taking within the first year of COVID-19, loneliness did predict greater sexual risk-taking 6 months later. Additionally, younger GBM and those living alone were more likely to engage in sexual risk-taking at both COVID-19 data collection points. These findings offer some support of the Loneliness and Sexual Risk Model; however, it is possible that the unique circumstances of the COVID-19 pandemic resulted in a temporary suspension of this association, as many GBM took steps to protect themselves and partners in the context of COVID-19. 相似文献

Violations of transitivity: Implications for a theory of contextual choice 总被引:1,自引:1,他引:0 下载免费PDF全文

Violations of strong stochastic transitivity in concurrent-chains choice were first reported by Navarick and Fantino. In a series of articles, Navarick and Fantino concluded that neither a unidimensional model capable of predicting exact choice probabilities nor a fixed-variable equivalence rule was possible for the concurrent-chains procedure. I show that when choice is modeled contextually (i.e., when preference for a schedule is affected by factors other than the schedule itself, e.g., aspects of the alternative schedule), a unidimensional, exact-choice probability model is possible that both predicts the intransitivities reported by Navarick and Fantino and provides a fixed-variable equivalence rule for the concurrent-chains procedure. The contextual model is an extension of the generalized matching law and violates a key assumption underlying traditional choice models—simple scalability—because of (a) schedule interdependence and (b) bias from procedural contingencies. Therefore, strong stochastic transitivity cannot be expected to hold. Contextual scalability is analyzed to reveal a hierarchy of context effects in choice. Navarick and Fantino's intransitivities can be satisfactorily explained by bias. If attribute sensitivity is context dependent, however, and if there are similarity structures among choice alternatives, the contextual model is shown to be able to predict violations of ordinal preference. Therefore, it may be possible to formulate a deterministic, general psychophysical model of choice as a behavioral alternative to probabilistic, multidimensional choice theories. 相似文献

In this paper, we propose an examination of the shared connections between the French philosopher, Maurice Merleau-Ponty and the Austro-Hungarian movement theorist, Rudolf Laban.In many ways Merleau-Ponty's philosophy demonstrates a synthesis of the best in existen-tialism and phenomenology. In like manner, Rudolf Laban was a synthesizer of experiences and theories of movement.we propose to examine the parallels and resonances of their theory within the forum of a hypothetical, collegial conversation. This dialogue will be prefaced by an historical contextualization of their work and an explanation of the appropriate reading sensibility with which to enter our interpretation of their text. In this way, we hope to reveal (a) possible parallels and resonances between their theories concerning the body in perception and movement, and (b) possible connections between phenomenology and movement education. 相似文献
