The relationship between individual differences in conjugate lateral eye movements (CLEMs) and inferential reasoning was investigated in two experiments. Subjects were given inference tasks in sentence and pictorial form and were later tested for recognition of correct inferences as well as literal recognition of the acquisition items. In Experiment 2, for example, subjects were given logical syllogisms during acquisition. Theoretically, right-eye movement/left-hemispheric (REM/LH) subjects should have excelled at this highly logical task but no significant differences between eye-movement groups were found. However, support for previous research showing the moderating effects of gender on hemispheric activation (measured by CLEMs) and hemispheric competence came from the memory data of Experiment 2. These data indicated that male REM/LH subjects recognized more acquisition sentences than the other eye movement/gender groups. It was suggested CLEMs and other measures of hemispheric activation and competence, coupled with data collected using complex cognitive tasks, can eventually lead to explanatory brain models of cognitive processing. 相似文献
Visuomanual sinusoidal tracking is investigated in 5- to 9-year-old children. The proportion of successful performances steadily increases with age, but adult proficiency is never attained even by those who can perform the task. Moreover, the progress in proficiency—as measured by systems analysis techniques—is not monotonic and suggests the presence of distinct stages in the development of visuomotor coordination. Qualitative analysis of unsuccessful performance demonstrates that failures cannot be ascribed only to insufficient motor coordination and emphasizes the role of cognitive and representational factors even in such a simple task. 相似文献
In sign languages, the task of communicating a shape involves drawing in the air with one moving hand (Method One) or two (Method Two). Since the movement path is iconic, method choice might be based on the shape. In the present studies we aimed to determine whether geometric properties motivate method choice. In a study of 17 deaf signers from six countries, the strongest predictors of method choice were whether the shape has any curved edges (Method One), and whether the shape is symmetrical across the Y‐axis (Method Two), where the default was Method One. In a second study of ASL dictionary entries for which the movement path of the sign is iconic of an entity's shape, the same predictors surfaced. These tendencies are captured in the Lexical Drawing Principle, which is coherent with biological constraints on movement in general. Drawing in the air with two hands, however, is costly, both cognitively and biomechanically. Furthermore, it distinguishes signers from non‐signers, who draw shapes with only one hand. Signers assume this extra cost in the lexicon because of the enhanced iconicity the possibility of two hands offers; they assume it in drawing shapes in the air because they apply the same linguistic principle they use in the lexicon. Additionally, having a choice of methods allows the signer to benefit from over‐specification in providing redundant information about the shape, enhancing comprehensibility and resolving ambiguity. 相似文献
Resurgence is often defined as the recurrence of an extinguished behavior when a more recently reinforced alternative behavior is also extinguished. Resurgence has also been observed when the alternative behavior is devalued by other means (e.g., reinforcement rate or magnitude reductions). The present study investigated whether punishment of an alternative behavior would generate resurgence. A target response was reinforced during Phase 1 and then extinguished in Phase 2 while an alternative response was reinforced. During Phase 3, response‐dependent foot shocks were superimposed on the schedule of reinforcement for the alternative response and shock intensity was escalated gradually across sessions. Resurgence of the target response was reliably observed, mostly at higher intensities. The effect was replicated in two subsequent exposures to the sequence of conditions, with resurgence tending to occur at the lowest foot shock intensity. These results suggest that devaluation of an alternative behavior via punishment can generate resurgence. Although it is difficult to reconcile the overall pattern of results with Bouton's context account, these findings are consistent with the suggestion that resurgence results from a “worsening of conditions” for the alternative behavior and with the formalization of that suggestion in terms of a choice‐based matching‐law account (i.e., Resurgence as Choice). 相似文献
Increasing the salience of aging has been shown to be a promising strategy to promote young adults' interest in saving for retirement. However, the processes responsible for this effect are still largely unknown. We hypothesize that increased savings choices will only occur when participants are also engaged in self‐relevant thoughts about their own future. Participants were exposed to a fictitious website advertising financial products. Study 1 (n = 78; Mage = 20.87) primed age salience and future self‐relevance orthogonally and showed that priming aging only caused increases in retirement investment decisions when self‐relevance was also high. Study 2 (n = 91; Mage = 23.40) tested whether the effects of age priming were due specifically to age or to a broader focus on the future. The study confirmed that investment decision effects are specific to exposure to the aging prime and not merely priming the future. The effects were also specific to investment in retirement funds and not just depositing money in a checking account. These findings have both theoretical and practical implications for the psychology of aging and retirement planning. 相似文献
Background: A systematic review was conducted to critically evaluate and synthesize literature investigating mental health practitioners' attitudes towards transgender people.
Objective: Three primary objectives were outlined; first, establish whether overall attitudes are positive or negative. Second, explore whether training, education or experience influences attitudes and finally, examine participant demographics in relation to attitude trends.
Method: A systematic electronic search was carried out in March 2017 using Medline, PsycINFO, PsycArticles, CINAHL, ASSIA, and Web of Science electronic databases. Manual citation and ancestral searches were conducted on identified papers. Qualitative, quantitative and mixed method studies were eligible for inclusion. A total of 13 papers of mixed quality were identified.
Results: Existing literature is limited to cross-sectional, quantitative data and fails to investigate differences between implicit and explicit attitudes. Small to moderate convenience samples reduce the generalizability of data. Overall attitudes were positive although negative attitudes were more frequent in male, Caucasian, heterosexual, religious, conservative mental health professionals.
Conclusions: Refined scales are needed to address the unique heterogeneity within transgender populations. Future research should focus on how attitudes impact care provided and employ longitudinal designs to explore the sustainability of targeted attitudinal training. 相似文献
