The sexualization of the breast may lead women who internalize the sexual objectification of their bodies to have more negative
attitudes toward breastfeeding. The purpose of the present study was to examine self-objectification in relation to young
women’s attitudes toward and concerns about breastfeeding. Two hundred and seventy-five female undergraduates completed a
survey with questions that assessed their plans for infant feeding, attitudes toward breastfeeding, concerns about breastfeeding,
and self-objectification. Women who scored higher on measures of self-objectification were more likely to view public breastfeeding
as indecent and to be concerned that breastfeeding would be embarrassing and would negatively impact their bodies and sexuality.
Self-objectification was not related to general attitudes toward breastfeeding or to young women’s future infant feeding plans.
Implications for theory and future research are discussed.
An earlier version of this study was presented at the annual meeting of the American Psychological Association, Washington,
DC (August, 2005). 相似文献

The present experiment examined the degree to which experience with different stimulus characteristics affects attentional capture, particularly as related to aging. Participants were presented with onset target/color singleton distractor or color singleton target/onset distractor pairs across three experimental sessions. The target/distractor pairs were reversed in the second session such that the target in the first session became the distractor in the second and third sessions. For both young and old adults previous experience with color as a target defining feature influenced oculomotor capture with task-irrelevant color distractors. Experience with sudden onsets had the same effect for younger and older adults, although capture effects were substantially larger for onset than for color distractors. Experience-based capture effects diminished relatively rapidly after target and distractor-defining properties were reversed. The results are discussed in terms of top-down and stimulus-driven effects on age-related differences in attentional control. 相似文献

This study investigated whether evaluative conditioning (EC) effects depend on an evaluative focus during the learning phase. An EC effect is a valence change of an originally neutral stimulus (conditioned stimulus or CS) that is due to the former pairing with a positive or negative stimulus (unconditioned stimulus or US). In three experiments, the task focus during the conditioning phase was manipulated. Participants judged CS–US pairings either with respect to their valence or with respect to another stimulus dimension. EC effects on explicit and implicit measures were found when valence was task relevant but not when the non-valent stimulus dimension was task relevant. Two accounts for the valence focus effect are proposed: (1) An additional direct learning of the relation of CS and evaluative responses in the valence focus condition, or (2) a stronger activation of US valence in the valence focus condition compared to the non-valent focus condition. 相似文献

Two experiments were conducted in which the latency of movement responses of varying complexity was investigated. The complexity of an arm sweep movement was varied by (a) increasing the extent of movement from 6 in. to 18 in., (b) reversing the movement, and (c) by making two or three pauses in an on-going movement. The results only partially supported the hypothesis that the latency of a response is related to the complexity of the movement pattern. Specifically RT was longer when the response involved significant changes in the temporal organization of the movement pattern. 相似文献

Mental speed is a common concept in theories of cognitive aging, but it is difficult to get measures of the speed of a particular psychological process that are not confounded by the speed of other processes. We used Bundesen’s (1990) Theory of Visual Attention (TVA) to obtain specific estimates of processing speed in the visual system controlled for the influence of response latency and individual variations of the perception threshold. A total of 33 non‐demented old people (69–87 years) were tested for the ability to recognize briefly presented letters. Performance was analyzed by the TVA model. Visual processing speed decreased approximately linearly with age and was on average halved from 70 to 85 years. Less dramatic aging effects were found for the perception threshold and the visual apprehension span. In the visual domain, cognitive aging seems to be most clearly related to reductions in processing speed. 相似文献

ABSTRACT The objective of the current study was to compare the trajectories of physiological levels of stress and self-report measures of mood in younger and older adults and to examine how a stress induction would affect performance. The current study examined physiological and subjective indicators of stress and mood before, mid-way through, and after being exposed to a stressful computer task. Stress levels and negative affect increased after stress induction relative to levels before and after the stressful task. Practice on the task helped to improve performance (accuracy and reaction time) but high workload measured during the task mitigated accuracy in younger and older adults, whereas it enhanced response speed in younger adults. 相似文献

ABSTRACT The neuropsychological test scores of 2,030 cognitively normal older adults were examined to evaluate performance patterns as they related to time of day (TOD) at which testing was initiated. Multiple regression analyses were used to examine the association of TOD with scores on seven neuropsychological tests used in the clinical evaluation of dementia. Episodic memory performance was significantly related to TOD, while memory span and verbal fluency were not. Best performance occurred during early morning hours and late afternoon; worst performance occurred mid-day (i.e., noon). These findings may have implications for clinical assessment, the design of research on dementia, and the daily functioning of older adults. 相似文献

ABSTRACT Context effects on episodic recognition memory involve separable contributions of target-context binding, additive familiarity, and configural constancy. Here we examine whether these factors reflect contributions of processes attributed to different brain substrates. First, we challenged frontal and medial temporal lobe-based cognitive capacities in healthy young adults, employing divided attention tasks at encoding and retrieval, and extended retrieval delay, respectively. Target-context binding effects were specifically attenuated by delay, but not by divided attention. In a second experiment, older adults were identified by neuropsychological testing as having different levels of frontal and medial temporal lobe-dependent cognitive functions. Consistent with Experiment 1, older adults with low medial temporal lobe function exhibited reduced target-context binding effects, but levels of frontal function did not modulate binding effects. These findings indicate that unlike source memory, context effects on memory are associated with the integrity of medial temporal lobe-based processes but not with the integrity of frontal lobe-based processes. Our findings also emphasize the importance of discriminating between functional subgroups in the attempt to characterize memory processes in older adults. 相似文献
