Irrelevant speech disrupts immediate recall of a short sequence of items. Salamé and Baddeley (1982) found a very small and nonsignificant increase in the irrelevant speech effect when the speech comprised items semantically identical to the to-be-remembered items, leading subsequent researchers to conclude that semantic similarity plays no role in the irrelevant speech effect. Experiment 1 showed that strong free associates of the to-be-remembered items disrupted serial recall to a greater extent than words that were dissimilar to the to-be-remembered items. Experiment 2 showed that this same pattern of disruption in a free recall task. Theoretical implications of these findings are discussed. 相似文献

Past research has led to the conclusion that two competing hypotheses are represented dependently, and confidence in them is updated in a complementary manner. It is argued here that confidence in two hypotheses can be represented either dependently or independently. Changes in confidence in the former case are always complementary, but changes in the latter case are complementary only under certain conditions. In three simulated medical diagnosis experiments, subjects learned about two illnesses in a manner expected to lead to either dependent or independent confidence. They were then presented with two symptoms sequentially (for each of several patients), updating confidence after each. Experiment 1 demonstrated that changes in confidence in the two illnesses were largely complementary for subjects with dependent, but not independent, confidence. Experiment 2 showed that encouraging consideration of the alternative led to more complementary changes for subjects with independent confidence. Experiment 3 succeeded in producing complementary changes from these subjects. Thus, complementarity does not imply dependent confidence, nor does independent confidence imply non-complementarity. 相似文献

US Air Force remote warrior personnel include a range of military personnel composed of remotely piloted aircraft aircrew, intelligence operators, and cyber warfare operators. Job duties in these professions entail long work hours, rotating shifts, and regular engagement in combat operations. Although research has identified a number of factors correlated with elevated burnout and emotional distress in this population, little is known about the unique needs of discrete subgroups of distressed personnel. In a sample of 7,550 US Air Force remote warriors, results of latent class analysis yielded four distinct classes. Three of the four reported moderately elevated burnout and job dissatisfaction but differed with respect to demographics and development career stage. The fourth group reported significantly higher levels of emotional distress, burnout, job dissatisfaction, and problems in living. This latter group was comparable to the mid-career group with respect to demographics, although this group had much lower levels of responsibility and indicators of career advancement. Results suggest that, among remote warrior personnel, there are several subtypes of elevated emotional distress. Prevention and intervention strategies that are matched to each subtype may yield better occupational and mental health outcomes than universal, “one size fits all” strategies. 相似文献

Decision makers typically overweight small probabilities and underweight large probabilities. However, there are recent reports that when probability is presented in the form of relative frequencies, this typical pattern reverses. We tested this hypothesis by comparing decision making in two tasks: In one task, probability was stated numerically, and in the other task, it was conveyed through a visual representation. In the visual task, participants chose whether a "stochastic bullet" should be fired at either a large target for a small reward or a small target for a large reward. Participants' knowledge of probability in the visual task was the result of extensive practice firing bullets at targets. In the classical numerical task, participants chose between pairs of lotteries with probabilities and rewards matched to the probabilities and rewards in the visual task. We found that participants' probability-weighting functions were significantly different in the two tasks, but the pattern for the visual task was the typical, not the reversed, pattern. 相似文献

Little is known about positive development across the transition from adolescence to young adulthood. The purpose of this paper was to use longitudinal data from a large community sample, the Australian Temperament Project, to investigate prospective associations between positive development at age 19?C20?years and changes in social, health, and behavioral outcomes at 23?C24?years. Data from 890 young adults (61.7% women) were analyzed using path analysis. Emotional health, physical well-being, friendship quality, reduced antisocial behavior, and positive development in young adulthood were predicted by higher levels of positive development in late adolescence, after controlling for baseline levels of respective outcomes, gender, and family socioeconomic status. Parent relationship quality and alcohol use were not significantly predicted. Based on these findings, interventions promoting positive development during adolescence should be investigated as a potential means of yielding positive social, health, and behavioral consequences well into young adulthood. 相似文献

BackgroundThere have been very limited long-term prospective studies examining social-cognitive models in the PA domain with large, representative population samples.ObjectiveThe primary objective was to examine the Theory of Planned Behaviour's (TPB) ability to explain PA behaviour in a randomly selected national sample of Canadian adults over a 15-year period. A secondary objective was to test the moderating effects of gender on TPB.DesignThe study employed a longitudinal design.MethodsA cohort of 1427 randomly-selected adults reported TPB constructs and PA behaviour in 1988, and again in 2003. Structural equation modelling techniques were employed to test TPB.ResultsThe full model including both 1988 and 2003 TPB measures accounted for 29% and 21% of the variance in intention, and 9% and 22% of the variance in PA in 1988 and 2003, respectively. Gender moderated aspects of the TPB in the full model. The core predictive model (1988 TPB constructs predicting 2003 PA behaviour) explained 13% of the variance in 2003 PA behaviour.ConclusionsThe TPB's long-term ability to predict PA behaviour is modest. 相似文献

Domestic dogs (Canis familiaris) and the radial arm maze: Spatial memory and serial position effects
M Craig J Rand R Mesch M Shyan-Norwalt J Morton E Flickinger 《Journal of comparative psychology (Washington, D.C. : 1983)》2012,126(3):233-242
The present study investigated spatial memory in domestic dogs (Canis familiaris) through the use of a radial arm maze. The study consisted of a total of three separate experiments. In the first two experiments, the ability of the dogs to successfully remember previously unentered arms was evaluated. The third experiment was similar to the first two, but also examined the nature of the serial position effect. Performance in all three experiments was better than expected solely by random choices. Dogs showed a much better memory for spatial locations presented earlier in a spatial list compared with those presented in the middle. Based on the present results, we suggest that the radial arm maze assesses canine spatial memory and that dogs show a primacy effect.

Five studies explored how perceived societal discrimination against one's own racial group influences racial minority group members' attitudes toward other racial minorities. Examining Black-Latino relations, Studies 1a and 1b showed that perceived discrimination toward oneself and one's own racial group may be positively associated with expressed closeness and common fate with another racial minority group, especially if individuals attribute past experiences of discrimination to their racial identity rather than to other social identities (Study 1b). In Studies 2-5, Asian American (Studies 2, 3, and 4) and Latino (Study 5) participants were primed with discrimination against their respective racial groups (or not) and completed measures of attitudes toward Black Americans. Participants primed with racial discrimination expressed greater positivity toward and perceived similarity with Blacks than did participants who were not primed. These results suggest, consistent with the common ingroup identity model (Gaertner & Dovidio, 2000), that salient discrimination against one's own racial group may trigger a common "disadvantaged racial minority" (ingroup) identity that engenders more positive attitudes toward and feelings of closeness toward other racial minorities. 相似文献
