This article focuses on the sexual attraction motive for skin bleaching in Jamaica. Some captive Africans on plantations in Jamaica altered their complexion. These Africans modeled the British in the colony who bleached their skin to protect the “superior,” “sexy,” and ideal white skin from the “impurities” of interracial sex and the tropical climate. The beauty and sexual attraction accorded to light skin was also evident in skin bleaching newspaper ads in the 1950s. The ads told women that acquiring light complexion through skin bleaching would make them sexually attractive to men. The persistence of colorism and its most blatant expression—skin bleaching—is also evident in contemporary Jamaica as expressed in some dancehall songs which praise skin bleachers, and the explanatory narratives of skin bleachers that bleaching makes them pretty and sexually attractive to potential spouses. Similar themes are reflected in the criticism that the browning Dancehall Queen Carlene was deemed sexually attractive and choreographically talented only because of her brown physicality. Some spouses request that their partner acquire the bleached physicality because they find it sexually attractive similar to many male clients in “massage parlors” who only request female sex workers who bleach their skin.  相似文献

It is generally accepted that, with practice, people improve on most tasks. However, when tasks have multiple parts, it is not always clear what aspects of the tasks practice or training should focus on. This research explores the features that allow training to improve the ability to resume a task after an interruption, specifically focusing on task-specific versus general interruption/resumption-process mechanisms that could account for improved performance. Three experiments using multiple combinations of primary tasks and interruptions were conducted with undergraduate psychology students. The first experiment showed that for one primary and interruption task-pair, people were able to resume the primary task faster when they had previous practice with the interruption. The second experiment replicated this finding for two other sets of primary and interruption task-pairs. Finally, the third experiment showed that people were able to resume a primary task faster only when they had previous practice with that specific primary and interruption task-pair. Experience with other primary and interruption task-pairs, or practice on the primary task alone, did not facilitate resumption. This suggests that a critical component in resuming after an interruption is the relationship between two tasks. These findings are in line with a task-specific mechanism of resumption and incompatible with a general-process mechanism. These findings have practical implications for developing training programs and mitigation strategies to lessen the disruptive effects of interruptions which plague both our personal and professional environments.  相似文献

Barth and Paladino (2011) argue that changes in numerical representations are better modeled by a power function whose exponent gradually rises to 1 than as a shift from a logarithmic to a linear representation of numerical magnitude. However, the fit of the power function to number line estimation data may simply stem from fitting noise generated by averaging over changing proportions of logarithmic and linear estimation patterns. To evaluate this possibility, we used conventional model fitting techniques with individual as well as group average data; simulations that varied the proportion of data generated by different functions; comparisons of alternative models' prediction of new data; and microgenetic analyses of rates of change in experiments on children's learning. Both new data and individual participants' data were predicted less accurately by power functions than by logarithmic and linear functions. In microgenetic studies, changes in the best fitting power function's exponent occurred abruptly, a finding inconsistent with Barth and Paladino's interpretation that development of numerical representations reflects a gradual shift in the shape of the power function. Overall, the data support the view that change in this area entails transitions from logarithmic to linear representations of numerical magnitude.  相似文献

Objective

The purpose of this study was to synthesize findings from motivational climate interventions employing [Ames, 1992a] and [Ames, 1992b] and [Epstein, 1988] and [Epstein, 1989] TARGET framework within school-based physical education contexts.

Design

The present study employed a quantitative research synthesis design. Meta-analysis uses empirical studies to summarize past research by drawing overall conclusions from separate investigations. This research design highlights important and unsolved issues related to motivational climate interventions within physical education.

Methods

Standard meta-analytic procedures incorporating inclusion and exclusion criteria, literature search, coding procedures, and statistical methods were used to identify and synthesize 22 studies with 24 independent samples. Cohen’s (1988) criteria for effect sizes were used to interpret and evaluate results.

Results

There was an overall small positive treatment effect (g = 0.103) for groups exposed to mastery motivational climates. Outcome analyses identified the most consistent and largest overall treatment effects for behavioral outcomes (g = 0.39–0.49) followed by affective outcomes (g = −0.27 to 0.59) and cognitive outcomes (g = −0.25 to 0.32). Moderator analyses were directed by study heterogeneity and identified several trends in intervention features and study features with the most substantial trend for participant features as elementary students had the largest overall treatment effect (g = 0.41).

Conclusions

Outcome and moderator analyses identified several trends in methodological features, participant features, and study features that should be addressed in future physical education motivational climate interventions.  相似文献

Aim: This exploratory study examined the relationship between clients’ involvement in therapy and their cognitive errors (CE) and coping action patterns (CAP). Method: Therapy sessions from N = 26 clients were rated for CE and CP using the CE and CAP methods. Client involvement was measured with the Positive and Negative Affect Schedule, as well as the . Results: The CEs’ ‘magnification of the negative or minimisation of the positive’ and ‘labelling’ were associated with measures of affective therapeutic engagement. The coping styles ‘negotiation’, ‘opposition’, ‘submission’, ‘isolation’, ‘support seeking’, ‘information seeking’, ‘delegation’, and ‘escape’ were found to be associated with affective and behavioural dimensions of therapeutic involvement. Conclusions: These findings provide preliminary supporting evidence that CE and CP are related to the extent to which clients engage in the work of therapy. Implications for researchers and therapists are discussed.  相似文献

This research examined how one affectively reacts to others' guesses at a value one cares about, such as one's income. Conventional wisdom suggests that people will feel happier upon receiving more favorable guesses (e.g., higher income) than less favorable guesses. We found the opposite pattern. We propose a model to explain the effect and identify its boundaries and report experimental evidence for the model. This research enriches existing literature on self-enhancement and yields practical implications for how to approach guessing in interpersonal communications.  相似文献

The habitual use of expressive suppression as an emotion regulation strategy has been consistently linked to adverse outcomes in a number of domains, including psychological functioning. The present study aimed to uncover whether the suppression-health relationship is dependent on cultural context, given differing cultural norms surrounding the value of suppressing emotional displays. We hypothesized that the negative associations between suppression and psychological functioning seen in European Americans would not be seen among members of East Asian cultures, in which emotional restraint is relatively encouraged over emotional expression. To test this hypothesis, we asked 71 European American students and 100 Chinese students from Hong Kong to report on their use of expressive suppression, life satisfaction, and depressed mood. A moderation analysis revealed that expressive suppression was associated with adverse psychological functioning for European Americans, but not for Chinese participants. These findings highlight the importance of context in understanding the suppression-health relationship.  相似文献

Four experiments explored effects on analogical transfer of evaluating solutions to base problems. In contrast to reports of positive effects of explanation, evaluation consistently reduced transfer rates and impaired mental representations of base material. This effect was not ameliorated by encoding for a later memory test, summarizing, or engaging in similar processes at encoding and recall. However, providing a prior explanation task removed the inhibitory effect of evaluation. It appears that evaluation leads to encoding of extraneous material that interferes with access to solution-critical analogous information. Prior explanation inoculates against negative effects on transfer by ensuring that new information introduced via evaluation is organized around existing representations of relevant information of the base problem. The results suggest that the source of difficulty in analogical transfer may reside not only in retrieval and mapping but also in the initial encoding of problems.  相似文献

We explored the effect of trunk orientation on responses to visual targets in five experiments, following work suggesting a disengage deficit in covert orienting related to changes in the trunk orientation of healthy participants. In two experiments, participants responded to the color of a target appearing in the left or right visual field following a peripheral visual cue that was informative about target location. In three additional experiments, participants responded to the location (left/right) of a target using a spatially compatible motor response. In none of the experiments did trunk orientation interact with spatial-cuing effects, suggesting that orienting behavior is not affected by the rotation of the body relative to the head. Theoretical implications are discussed.  相似文献

Contrast thresholds for the detection of flicker and the detection of pattern were measured for nasal and temporal retinae of each eye separately. While confirming that these two types of threholds can differ, depending on the spatial frequency, the results provide no support for hemiretinal or hemispheric asymmetries in the distribution of the putative pattern and movement channels.  相似文献
