Repetition priming is one of the most robust phenomena in cognitive psychology, but participants vary substantially on the amount of priming that they produce. The current experiments assessed the reliability of repetition priming within individuals. The results suggest that observed differences in the size of the repetition priming effect across participants are largely reliable and result primarily from systematic processes. We conclude that the unreliability of semantic priming observed by Stolz, Besner, and Carr (2005) is specific to uncoordinated processes in semantic memory, and that this unreliability does not generalize to other processes in visual word recognition. We consider the implications of these results for theories of automatic and controlled processes that contribute to priming. Finally, we emphasize the importance of reliability for researchers who use similar paradigms to study individual and group differences in cognition. 相似文献

Depression is one of the most common psychological disorders. It is associated with tremendous costs in terms of suffering, decrease in productivity, and loss of life. For many individuals, depression is a disorder that will recur throughout life. Recent findings suggest that the prevalence of depression is on the rise, particularly in young people. Clearly, depression prevention is an important goal. Can depression be prevented? In this article we review research on interventions designed to prevent episodes and symptoms of unipolar depression in adults and children. Our review focuses specifically on cognitive-behavioral and family interventions. We discuss what researchers have learned about the prevention of depression and conclude with recommendations for future investigations. 相似文献

One perennial policy question in Canada concerns the kind of immigrants Canada should admit. Should it be those with the best prospects of fast economic assimilation in the labour market?. This research note sketches the earnings outcomes of immigrants associated with different admission categories. Specifically, we examine two databases. The Immigration Data Base (IMDB) provides information on admission categories by linking immigration, administrative records with income tax files. The Survey of Labour and Income Dynamics (SLID) is a longitudinal sample that provides a comprehensive profile of immigrants and native-born Canadians. The IMDB and SLID datasets provide valuable information on the economic outcomes of immigrants in quite different ways. 相似文献

Despite recent findings suggesting the presence of racial differences in the perception of starting salaries, researchers have yet to empirically investigate this possibility. Consequently, this study examined the interactive effects of race, ethnic identity, and starting salaries on the salary perceptions of 342 undergraduates. Hispanic, Asian American, and White participants exhibited positive effects of salary whereas Black respondents failed to discriminate between the different salaries. However, a three-way interaction involving ethnic identity, race, and salary revealed a more complex pattern of responses for Black participants: Higher ethnic identifiers responded similarly to Hispanic, White, and Asian Americans. The implications of these results regarding the perpetuation of racial wage inequity are discussed. 相似文献

In this paper, we consider the different methods that have been developed to quantify random generation behavior and incorporate these measurement scales into a Windows95 computer program called RgCalc. RgCalc analyzes the quality of human attempts at random generation and can provide computer-generated, pseudorandom sequences for comparison. The program is designed to be appropriate for the analysis of various types of random generation situations employed in the psychological literature. The different algorithms for the evaluation of a dataset are detailed and an outline of the program is described. Performance measures are available for assessing various aspects of the response distribution, the sequencing of pairs, the ordinal relationships between sets of items, and the tendency to repeat alternatives over different lengths. A factor analysis is used to illustrate the multiple dimensions underlying human randomization processes. 相似文献

Three pigeons were trained in an upright conditioning chamber to peck a key transilluminated by a vertical line. This training was followed by a line orientation generalization test. During the test, the chamber was tilted laterally 22.5 degrees from upright. The chamber floor remained horizontal with respect to gravity. Under these conditions, the subjects responded more often in the presence of a visually vertical (parallel to chamber walls) line orientation than in the presence of a gravitationally vertical line orientation. Subsequent reinforcement of pecking in the presence of a line that was always gravitationally vertical but not always visually vertical temporarily abolished this "visual field dependency" and resulted in generalization gradients with peak responding in the presence of the gravitationally vertical line orientation. The results are discussed in terms of selective attention to the gravitational and visual components of line orientation. 相似文献

Stimulus control of responding during a fixed-interval reinforcement schedule 总被引:1,自引:1,他引:0 下载免费PDF全文

During training sessions, pecks by pigeons on a response key illuminated by a vertical line of white light resulted in reinforcement and an ensuing blackout according to a fixed-interval schedule. Training sessions were followed by dimensional stimulus control test sessions during which the orientation of the line present throughout the fixed interval was varied. Inverted U-shaped (excitatory) gradients of responding, with maximum responding occurring in the presence of the vertical line, were observed during the terminal part of the fixed interval. U-shaped (inhibitory) gradients of responding, with minimum responding occurring in the presence of the vertical line, were observed during the early part of the fixed interval when the preceding interval had terminated with reinforcement and blackout but not when the preceding interval had terminated with blackout only. These results suggest that the dimensional control by the stimulus present throughout the fixed interval is of a conditional variety. Whether the fixed-interval stimulus exerts inhibitory or excitatory dimensional control depends upon the presence and absence, respectively, of stimuli associated with reinforcement. 相似文献

Reformation theology has two significant contributions to make to a renewal of environmental theology. Its heritage of sin exposes the fact that human efforts at intervention in the environment are only ambiguously good and in need of redemption themselves. Its heritage of freedom exposes some efforts toward environmental healing as works‐righteousness, available to be transformed by God in hope for a heavenly and earthly future. 相似文献

Toward quantifying the abuse liability of ultraviolet tanning: A behavioral economic approach to tanning addiction 下载免费PDF全文

Many adults engage in ultraviolet indoor tanning despite evidence of its association with skin cancer. The constellation of behaviors associated with ultraviolet indoor tanning is analogous to that in other behavioral addictions. Despite a growing literature on ultraviolet indoor tanning as an addiction, there remains no consensus on how to identify ultraviolet indoor tanning addictive tendencies. The purpose of the present study was to translate a behavioral economic task more commonly used in substance abuse to quantify the "abuse liability" of ultraviolet indoor tanning, establish construct validity, and determine convergent validity with the most commonly used diagnostic tools for ultraviolet indoor tanning addiction (i.e., mCAGE and mDSM‐IV‐TR). We conducted a between‐groups study using a novel hypothetical Tanning Purchase Task to quantify intensity and elasticity of ultraviolet indoor tanning demand and permit statistical comparisons with the mCAGE and mDSM‐IV‐TR. Results suggest that behavioral economic demand is related to ultraviolet indoor tanning addiction status and adequately discriminates between potential addicted individuals from nonaddicted individuals. Moreover, we provide evidence that the Tanning Purchase Task renders behavioral economic indicators that are relevant to public health research. The present findings are limited to two ultraviolet indoor tanning addiction tools and a relatively small sample of high‐risk ultraviolet indoor tanning users; however, these pilot data demonstrate the potential for behavioral economic assessment tools as diagnostic and research aids in ultraviolet indoor tanning addiction studies. 相似文献
