Do words cue children's visual attention, and if so, what are the relevant mechanisms? Across four experiments, 3‐year‐old children (= 163) were tested in visual search tasks in which targets were cued with only a visual preview versus a visual preview and a spoken name. The experiments were designed to determine whether labels facilitated search times and to examine one route through which labels could have their effect: By influencing the visual working memory representation of the target. The targets and distractors were pictures of instances of basic‐level known categories and the labels were the common name for the target category. We predicted that the label would enhance the visual working memory representation of the target object, guiding attention to objects that better matched the target representation. Experiments 1 and 2 used conjunctive search tasks, and Experiment 3 varied shape discriminability between targets and distractors. Experiment 4 compared the effects of labels to repeated presentations of the visual target, which should also influence the working memory representation of the target. The overall pattern fits contemporary theories of how the contents of visual working memory interact with visual search and attention, and shows that even in very young children heard words affect the processing of visual information.  相似文献

How far does a researcher’s responsibility extend when an incidental finding is identified? Balancing pertinent ethical principles such as beneficence, respect for persons, and duty to rescue is not always straightforward, particularly in neuroimaging research where empirical data that might help guide decision making are lacking. We conducted a systematic survey of perceptions and preferences of 396 investigators, research participants, and Institutional Review Board members at our institution. Using the partial entrustment model as described by Richardson, we argue that our data supports universal reading by a neuroradiologist of all research MRI scans for incidental findings and providing full disclosure to all participants.  相似文献

In today's global marketplace, the Philippines provide a unique example of an Asian culture with established economic ties to the West. In this study, Philippine and United States undergraduate business students responded to 13 vignettes describing questionable ethical actions in business situations. Results reveal significant differences between groups for 9 of the 13 vignettes. For 4 vignettes, Philippine participants were more disapproving of the actions, and for another 5, United States participants were more disapproving. The study suggests that cultural differences continue and the implications of these differences should be considered in today's global economy.  相似文献

For our field to truly understand women's use of IPV, it is crucial that the following three steps be taken by researchers to put context back into the equation: (a) incorporate the effects of multiple oppressions women face within the context of predominantly male offending across different types of violent criminal categories (top level); (b) integrate findings from both objective and subjective IPV research methods that will require elevating subjective approaches to the same status as objective (middle level); and (c) centralize the issue of ongoing patterns of coercion, power, and control within our definitions of IPV (individual level). Without such an embedded approach, our field will continue to divert much-needed resources toward the so-called gender symmetry debate and run the risk of helping to perpetuate further injustices against women.  相似文献

This article presents the results of a study assessing the needs and experiences of African American and White female survivors of sexual assault in the state of Maryland. Eight specific hypotheses regarding differences in the needs and experiences of African American as compared to White women receiving partial or no support through analyses of interview data drawn from 213 survivors (African American survivors, n = 133; White survivors, n = 80) were explored. No differences were reported in medical care received; however, in comparison to their White counterparts, African American women reported decreased use of sexual assault crisis centers and mental health services, and postassault help-seeking through use of sexual assault hotlines. Barriers and facilitators associated with treatment experiences differed by ethnicity. Findings are discussed in relation to future directions for research, and service and policy improvement for survivors of sexual assault.  相似文献

Two experiments were conducted to investigate sex differences in risktaking behavior on a computer-generated and controlled task. Male and female subjects faced a video display of simulated mine fields with varying numbers and patterns of dots representing mines in the fields. In Experiment 1, they estimated the probability that a tank might successfully cross 100 mine fields when starting from an unknown point below each field. This was followed by the risk-taking task in which they decided whether to send a tank across each of the fields. The participants were tested on the risk-taking task once in Experiment 1 and over four separate sessions in Experiment 2. Scores, based on decision outcomes, and decision latencies were recorded. No significant sex differences were found in the participants' ability to estimate probabilities or in their total scores for decisions made on the risk-taking task. In low probability-of-success situations, women initially took greater risks than men but took longer to make their decisions; in all subsequent sessions, this pattern was reversed, with men taking greater risks and a longer time to make decisions. The findings support the growing body of evidence that men are more inclined to take risks than women in a variety of situations, indicate the importance of obtaining data over repeated sessions when investigating sex differences in risk taking, and demonstrate that computer-simulated tasks can provide a valid means for laboratory studies of sex differences in risk taking.  相似文献

This study makes use of the basic experimental research on the social psychology of experiments in understanding the jury-selection process. A survey asked ex-jurors to report on their experiences during jury selection. The ex-jurors reported on the factors that influenced the honesty of their responses during voir dire. The findings were consistent with previous laboratory results, with evaluation anxiety producing the most significant changes in juror honesty. However, both evaluation anxiety and demand characteristics influenced juror behavior depending on the motives of the juror. Expectancies of judges and lawyers appeared to have little effect on the reported honesty of ex-jurors.  相似文献
