Zap! Magnetic tricks on conscious and unconscious vision 总被引:2,自引:0,他引:2

Blindsight, the remarkable capability to react to unseen visual stimuli, has thus far only been demonstrated in patients and monkeys with a lesion to primary visual cortex. A recent study by Boyer, Harrison and Ro demonstrates blindsight in normal human observers, using TMS to block visual processing. Combined with other work, this opens new vistas towards understanding mechanisms of conscious and unconscious vision. 相似文献

Dyadic caregiving decision making was studied in 30 mother-son and 29 mother-daughter pairs (mother's age=65-94 years) who responded to a vignette depicting a caregiving decision situation. The observed decision-making process of mother-child pairs was largely naturalistic, with few alternatives proposed and quick convergence to a decision followed by a postdecision justification; a degree of more rational decision making was seen in some pairs. Among significant findings, adult children, especially sons, dominated the decision process, doing more talking and introducing more alternatives than did their mothers, who played a more subordinate role. Mother-son pairs expected more negative outcomes and greater regrets regarding their decisions than mother-daughter pairs. Closeness of the parent-child relationship influenced the decision-making process, expected outcomes, and regrets. 相似文献

By employing visual lexical decision and functional MRI, we studied the neural correlates of morphological decomposition in a highly inflected language (Finnish) where most inflected noun forms elicit a consistent processing cost during word recognition. This behavioral effect could reflect suffix stripping at the visual word form level and/or subsequent meaning integration at the semantic-syntactic level. The first alternative predicts increased activation for inflected vs. monomorphemic words in the left occipitotemporal cortex while the second alternative predicts left inferior frontal gyrus and/or left posterior temporal activation increases. The results show significant activation effects in the latter areas. This provides support for the second alternative, i.e., that the morphological processing cost stems from the semantic-syntactic level. 相似文献

In an associative recognition task, distractors generally consist of a rearrangement of the items composing the study pairs.
This makes it possible that processing the distractors generates retroactive interference on memory for the study pairs. In
Experiment 1, we explored this possibility in ayes/no recognition test concerning previously learned arbitrary associations between visual symbols and auditory syllables. Rearranged
pairs had a deleterious impact on the accuracy and the speed of responses to related correct pairs. This effect did not vary
as a function of the number of training blocks, and furthermore, in Experiment 2, the same effect was observed for overlearned
small multiplication facts. These results suggest that exposure to potentially confounding information generates interference
even if this information is known to be incorrect. Some implications are outlined, especially with regard to the widespread
use of multiple-choice tests in knowledge evaluation. 相似文献

In this study, the authors examined the stability of Minnesota Multiphasic Personality Inventory--2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) code types in a sample of 94 injured workers with a mean test-retest interval of 21.3 months (SD = 14.1). Congruence rates for undefined code types were 34% for high-point codes, 22% for 2-point codes, and 22% for 3-point codes. The data provide tentative evidence suggesting that defined code types are more stable than undefined code types. Cohen's kappa, a statistic that controls for chance agreement, was calculated for each clinical scale for both 2-point and 3-point code types. Only 2 of the 20 kappa coefficients were not significant at the p = .05 level. 相似文献

The present study examined the impact of different modes of processing anxious apprehension on subsequent anxiety and performance in a stressful speech task. Participants were informed that they would have to give a speech on a difficult topic while being videotaped and evaluated on their performance. They were then randomly assigned to one of three conditions. In a specific processing condition, they were encouraged to explore in detail all the specific aspects (thoughts, emotions, sensations) they experienced while anticipating giving the speech; in a general processing condition, they had to focus on the generic aspects that they would typically experience during anxious anticipation; and in a control, no-processing condition, participants were distracted. Results revealed that at the end of the speech, participants in the specific processing condition reported less anxiety than those in the two other conditions. They were also evaluated by judges to have performed better than those in the control condition, who in turn did better than those in the general processing condition. 相似文献

The principal aim of this study is to determine why police officers are generally found to be more prejudiced towards disadvantaged groups than are the standard population. Two independent processes were expected to account for this effect: Selection and group socialisation. Using a cross‐sectional design (N = 170), firstly, we compared, newly recruited police officers with a control population (selection effect), and secondly, police officers with 1 year of training with the newly recruited ones (group socialisation effect). Results reveal a significant effect of both selection and group socialisation, the two being underlined by distinct processes; right‐wing authoritarianism (RWA) in the case of the former and internalisation of a prejudice norm in the case of the latter. Finally, the results show that group identification moderates the change in internalisation of the prejudice norm. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The purpose of this study was to compare the effectiveness of two different forms of reciprocal peer tutoring (RPT) on the motor and cognitive performance of adolescents in a physical education setting. We also explored the influence of gender. We assigned 72 ninth-graders (36 M, 36 F), all novices in a table tennis task, to a 2 × 3 (Gender × Learning Condition: physical practice with trained RPT [TRPT] vs. physical practice with spontaneous RPT [SRPT]vs. physical practice without any form of RPT [PP; individual control condition]) factorial design. Results indicated superior motor performance and cognitive skills for the TRPT condition and no difference between the SRPT and PP conditions. The peer-tutor training was thus a crucial organizational variable of the success of RPT. Interestingly, our results support the assumption that females particularly benefit from a highly structured peer tutoring framework. 相似文献
