Under the guise of an experiment on gambling decisions, subjects briefly met a confederate of the experimenter, whom they later evaluated. The major hypothesis was that the confederate would be evaluated more favorably by subjects who were told that she had received a fortuitous reward than by control subjects. The hypothesis was confirmed for female subjects only. 相似文献

Van Orden (1987) reported that false positive errors in a categorization task are elevated for homophonic foils (e.g., HARE for A PART OF THE HUMAN BODY). Two new experiments replicate this finding and extend it to nonword homophone foils (e.g., SUTE FOR AN ARTICLE OF CLOTHING). False positive errors to nonword homophone foils substantially exceed false positive errors to nonhomophonic nonword spelling controls, showing that the phonological characteristics of the nonword foils are critical. Because nonwords are not represented in the lexicon, this new result implicates computed phonological codes as a source of the categorization errors. Additionally, in each of two experiments, matched word and nonword homophones produced virtually identical error rates. If stimulus nonword homophones are viewed as extremely unfamiliar words, compared with the relatively familiar stimulus word homophones, then our failure to observe an effect of stimulus familiarity strengthens the case that phonological coding plays a role in the identification of all printed words. The fact that the results are obtained in a categorization task that requires reading for meaning (rather than a lexical decision task) makes it difficult to avoid the conclusion that phonological mediation plays a role in normal reading of text for meaning. 相似文献

Over the past fifteen years, behavior analysts in Florida have worked together to develop the discipline with a multifaceted system of contingencies. Basing their effort in the area of retardation and with the cooperation of the state's Developmental Services Program Office, they have gradually developed a regulatory manual of programming policy and procedures, a hierarchical system of responsibilities for programming approval and monitoring, a state-sponsored certification program, a professional association, and an active university community. These components are described and discussed in terms of suggested principles for developing the field of behavior analysis within a state. 相似文献

Levels of adult alcohol consumption induced by interactions with child confederates exhibiting normal versus externalizing behaviors 总被引:2,自引:0,他引:2
Investigated levels of distress and alcohol consumption in Ss interacting with problematic vs non-problematic child confederates. Social drinkers were randomly assigned to interact with boys trained to enact behaviors characteristic of either normal or attention-deficit disorder/conduct disorder (ADD/CD) children. Mood data were collected before and after the interaction. Ss engaged in ad lib beer consumption for 20 min, while anticipating another interaction with the same boy. Children in the ADD/CD role produced comparably distressed moods for both male and female Ss. However, only men drank to higher blood-alcohol levels in the ADD/CD vs. normal child condition. Results suggest that higher rates of drinking observed in fathers of ADD/CD children may be partly a function of their particular response to the distress associated with interactions with such children. 相似文献

Despite the fact that sex differences in field dependence/independence have been a fairly constant feature in studies employing adults, doubt surrounds the status of similar sex differences in childhood. Several attempts have been made to explain these findings, the most popular being that group Embedded Figures Tests do not tap sex differences. A simpler explanation is that large enough Ns have not been employed in past research to allow the small sex difference present in childhood to emerge as a statistically significant phenomenon. This explanation is supported by the results of the present study which employed 1200 children and was able to demonstrate a significant sex difference at both 8 and 11 yr using the Children's Group Embedded Figures Test. 相似文献

Anxiety sensitivity (AS) has been linked to a variety of disabling chronic health conditions, including pain-related conditions. A recent study has found that healthy women with high AS reported significantly higher levels of sensory and affective pain on an experimental cold pressor task compared to women with low AS. However, this study found no differences between AS groups for pain tolerance or pain threshold. In the present study, which was designed to replicate and extend these findings, 90 undergraduate university women were selected for inclusion in 1 of 2 AS groups (high or low) based on their screening scores on a 16-item measure of AS. Participants were tested individually on a lab-based cold pressor task using a variety of self-report and observer-measured variables. Data analyses revealed that, as expected, the high AS participants reported significantly more fear in response to the cold pressor on a relevant item of the McGill Pain Questionnaire-Short Form (SF-MPQ) than did the low AS participants. Also as expected, the high AS participants reported more pain in response to the cold pressor on the Present Pain Index (PPI) of the SF-MPQ than did the low AS participants. High AS participants did not differ from low AS participants on other aspects of the cold pressor response (e.g. pain threshold, pain tolerance, pain recovery). These results support the role of pain-related fear as a mediating variable between AS and increased perceived pain intensity. 相似文献

Little Bayesians or little Einsteins? Probability and explanatory virtue in children's inferences 下载免费PDF全文
Angie M. Johnston Samuel G.B. Johnson Marissa L. Koven Frank C. Keil 《Developmental science》2017,20(6)
Like scientists, children seek ways to explain causal systems in the world. But are children scientists in the strict Bayesian tradition of maximizing posterior probability? Or do they attend to other explanatory considerations, as laypeople and scientists – such as Einstein – do? Four experiments support the latter possibility. In particular, we demonstrate in four experiments that 4‐ to 8‐year‐old children, like adults, have a robust latent scope bias that leads to inferences that do not maximize posterior probability. When faced with two explanations equally consistent with observed data, where one explanation makes an unverified prediction, children consistently preferred the explanation that does not make this prediction (Experiment 1), even if the prior probabilities are identical (Experiment 3). Additional evidence suggests that this latent scope bias may result from the same explanatory strategies used by adults (Experiments 1 and 2), and can be attenuated by strong prior odds (Experiment 4). We argue that children, like adults, rely on ‘explanatory virtues’ in inference – a strategy that often leads to normative responses, but can also lead to systematic error. 相似文献
