Intact perception of biological motion in the face of profound spatial deficits: Williams syndrome 总被引:8,自引:0,他引:8
Williams syndrome (WS) is a rare genetic disorder that results in profound spatial cognitive deficits. We examined whether individuals with WS have intact perception of biological motion, which requires global spatial integration of local motion signals into a unitary percept of a human form. Children with WS, normal mental-age-matched children, and normal adults viewed point-light-walker (PLW) displays portraying a human figure walking to the left or right. Children with WS were as good as or better than control children in their ability to judge the walker's direction, even when it was masked with dynamic noise that mimicked the local motion of the PLW lights. These results show that mechanisms underlying the perception of at least some kinds of biological motion are unimpaired in children with WS. They provide the first evidence of selective sparing of a specialized spatial system in individuals with a known genetic impairment. 相似文献

While the sample size is too small to warrant conclusions, these preliminary results suggest that assessment of depression would be worthwhile for patients diagnosed with congestive heart failure. 32 out of 54 patients with congestive heart failure scored positive for depression. When psychiatric treatment was given, there was a decrease in depressive symptoms for four of the six patients at the 6-mo, retest. A decrease in depressive symptoms was found for two of the six untreated patients, and the remaining four patients had worse scores on the Zung Depression Inventory. Primary care physicians, who typically meet with such patients regularly, are encouraged to screen for depression, as their clinical assessments in this study were associated with scores on the Zung Depression Inventory. These observations support a full scale investigation with a much larger sample size and a requisite medical cost comparison. 相似文献

Hearing the sound of laughter is important for social communication, but processes contributing to the audibility of laughter remain to be determined. Production of laughter resembles production of speech in that both involve visible facial movements accompanying socially significant auditory signals. However, while it is known that speech is more audible when the facial movements producing the speech sound can be seen, similar visual enhancement of the audibility of laughter remains unknown. To address this issue, spontaneously occurring laughter was edited to produce stimuli comprising visual laughter, auditory laughter, visual and auditory laughter combined, and no laughter at all (either visual or auditory), all presented in four levels of background noise. Visual laughter and no-laughter stimuli produced very few reports of auditory laughter. However, visual laughter consistently made auditory laughter more audible, compared to the same auditory signal presented without visual laughter, resembling findings reported previously for speech. 相似文献

In Study 1, 20 incurious worry reduction motive (IWRM) items were administered to 280 participants along with curiosity and worry scales. With factor analysis, two six‐item scales were developed: focus on distress (IWRM‐FD) and focus on relief (IWRM‐FR). IWRM‐FD was associated with wanting positive news about threats, whereas IWRM‐FR was related to wanting negative news to be free from further worry. Neither the curiosity nor worry scales predicted wanting information. In Study 2, the IWRM scales were administered to 170 participants along with a coping inventory. IWRM‐FD correlated with avoidant‐coping, whereas IWRM‐FR was associated positively with active‐coping and advice‐seeking. The results suggest that IWRM‐FD reflects a desire to minimize distress, whereas IWRM‐FR motivates identifying and dealing directly with problems. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This investigation examined the relationship between organizationally based financial incentives and a focus on profit vs. prosociality during decision making. Participants were 84 managers from a Fortune 200 corporation. Managers read a vignette containing a dilemma and freely generated issues that they considered important in resolving the dilemma. These responses were coded for their inclusion on 3 dimensions: financial profitability, well‐being of nonpowerful stakeholders, and legal culpability. The results demonstrated that salary level predicted an increased focus on the dimension related to financial profitability and decreased focus on the dimensions of prosociality and legal concerns. Implications of these findings and future directions for research are discussed. 相似文献

Contemporary comparative cognition has a large repertoire of animal models and methods, with concurrent theoretical advances that are providing initial answers to crucial questions about human cognition. What cognitive traits are uniquely human? What are the species-typical inherited predispositions of the human mind? What is the human mind capable of without certain types of specific experiences with the surrounding environment? Here, we review recent findings from the domains of space, time and number cognition. These findings are produced using different comparative methodologies relying on different animal species, namely birds and non-human great apes. The study of these species not only reveals the range of cognitive abilities across vertebrates, but also increases our understanding of human cognition in crucial ways. 相似文献

In 2015, AshleyMadison.com (AshleyMadison) was hacked, leading to the release of site members’ personal information. The exposed members faced public scrutiny, judgment, and other negative outcomes. In this study, we examined predictors of the demonization of the AshleyMadison participants (i.e., AshleyMadison members, owners, hackers) to help explain victim derogation. We attempted to discern the role religiosity and sexual guilt played in the demonization of the AshleyMadison hacking participants. We predicted sexual guilt would mediate between religiosity and demonization of the AshleyMadison hacking participants. Our findings indicate that religiosity alone does not predict demonization. Instead, sex guilt was a necessary part of the equation and mediated between participants’ religiosity and the amount they demonized the different groups. 相似文献

The purpose of the study was to examine the effectiveness of the micro‐expressions training tool (METT) in identifying and using micro‐expressions to improve lie detection. Participants (n = 90) were randomly assigned to receive training in micro‐expressions recognition, a bogus control training, or no training. All participants made veracity judgements of five randomly selected videos of targets providing deceptive or truthful statements. With the use of the Bayesian analyses, we found that the METT group did not outperform those in the bogus training and no training groups. Further, overall accuracy was slightly below chance. Implications of these results are discussed. 相似文献

This study examined contextual control of long-term habituation and whether such effects are dependent on the habituating response system. Habituation of the acoustic startle response transferred from the home cage to the testing context, whereas habituation of lick suppression was context specific (Experiments 1 and 2). Contextual control of habituation was demonstrated between 2 experimental contexts for lick suppression to a tone (Experiment 3) and bar-press suppression to a light (Experiment 4). Experiment 5 extinguished habituation of lick suppression and the orienting response to a tone with 27 exposures to the habituation context. Context specificity of both responses also was found. Previous failures to demonstrate contextual control of habituation may be due to the choice of response system and to less sensitive procedures to detect response recovery. The habituation mechanism for startle is independent from the process or processes that underlie habituation in other response systems, but the nature of these mechanisms is not yet known. 相似文献
