The scientific community has witnessed growing concern about the high rate of false positives and unreliable results within the psychological literature, but the harmful impact of false negatives has been largely ignored. False negatives are particularly concerning in research areas where demonstrating the absence of an effect is crucial, such as studies of unconscious or implicit processing. Research on implicit processes seeks evidence of above-chance performance on some implicit behavioral measure at the same time as chance-level performance (that is, a null result) on an explicit measure of awareness. A systematic review of 73 studies of contextual cuing, a popular implicit learning paradigm, involving 181 statistical analyses of awareness tests, reveals how underpowered studies can lead to failure to reject a false null hypothesis. Among the studies that reported sufficient information, the meta-analytic effect size across awareness tests was d z = 0.31 (95 % CI 0.24–0.37), showing that participants’ learning in these experiments was conscious. The unusually large number of positive results in this literature cannot be explained by selective publication. Instead, our analyses demonstrate that these tests are typically insensitive and underpowered to detect medium to small, but true, effects in awareness tests. These findings challenge a widespread and theoretically important claim about the extent of unconscious human cognition. 相似文献

Background and Objectives: Emerging adulthood is often marked with elevated symptoms of anxiety and depression. Hispanic emerging adults may face cultural stressors such as ethnic discrimination that further increase levels of anxiety and depression symptoms. The study aims were to examine if (a) self-esteem mediated effects of ethnic discrimination on symptoms of anxiety and depression, and (b) if gender moderated the indirect effects of discrimination. Design: The study design was cross-sectional self-report. Method: Two moderated mediation models were tested, with 1084 Hispanic emerging adults (ages 18–25) enrolled in institutions of post-secondary in the United States. Results: Results indicated that (a) higher ethnic discrimination was associated with higher anxiety symptoms (β?=?.05, p?=?.04), higher depression symptoms (β?=?.06, p?=?.02), and lower self-esteem (β?=??.30, p?.001); (b) self-esteem mediated the associations of ethnic discrimination with anxiety and depression symptoms; and (c) gender moderated the indirect effects of discrimination, whereby self-esteem was a stronger mediator among men than women. Each moderated mediation model explained 26% of variability in symptoms of anxiety and depression, respectively. Conclusions: Findings suggest that the mediating effects of self-esteem linking ethnic discrimination with symptoms of anxiety and depression vary between genders. 相似文献

The aim of this study was to teach left/right (Experiment 1) and near/far (Experiment 2) discrimination with reference both to self and to another person. The procedures used involved teaching discrimination in expressive language (speaker behavior) and then testing the transfer of learning into receptive language (listener behavior). A total of six intellectually disabled adults took part in the study, four in Experiment 1 and two in Experiment 2. The results showed that the subjects learned the target behavior in expressive language and performed correctly in tests to confirm the transfer of learning to receptive language. Experiments to analyze the function of the stimuli involved in receptive language share a certain amount of common ground with research into conditional discrimination under contextual control. The procedures used in such experiments may additionally enhance the teaching of visuospatial perspective‐taking skills. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

This study examines the mediating role of effortful control between reactive temperament traits (negative affectivity and extraversion) and children’s internalizing and externalizing behavioural problems. The sample was composed of 424 non-clinical children from 3 to 6 years of age (60% male). Use of a structural equation model revealed effortful control-mediated relations between reactive temperament traits and behavioural problems. Nevertheless, uniquely and directly, negative affect predicted externalizing problems and extraversion predicted internalizing problems. Assessment of invariance by children’s sex showed that the mediating role of effortful control tends to be stronger for externalizing problems in boys than in girls. Results showed no significant age differences. According to these results, effortful control as a method of self-regulation seems to be an essential process through which reactive temperament traits affect a child’s psychological adjustment. 相似文献

We offer the new software Codex, written in Visual Basic 3.0. It is a tool adequate in observational methodology. Its fundamental objective is to record motor and verbal behavior using the data types proposed by Bakeman and Quera (1995, 1996), together with the field formats proposed by Hall (1963), Weick (1968), Hutt and Hutt (1974), and Anguera (1979). It is designed to allow for data interchange between specific programs in use in observational methodology (SDIS-GSEQ, The Observer, and Theme) and other general programs (spread sheets, statistics applications, word processing programs, sound cards, etc.). 相似文献

The purpose of this paper is threefold. First, I visit the Fogelin–Geach-dispute, criticizeMiller's interpretation of the Geachian notationN(x:N(fx)) and conclude that Fogelin's argumentagainst the expressive completeness of the Tractariansystem of logic is unacceptable and that the adoptionof the Geachian notation N(x:fx) would not violate TLP5.32. Second, I prove that a system of quantificationtheory with finite domains and with N as the solefundamental operation is expressively complete. Lastly, I argue that the Tractarian system is apredicate-eliminated many-sorted theory (withoutidentity) with finite domains and with N as the solefundamental operation, and thus is expressivelycomplete. 相似文献
