Action observation (AO) and movement imagery (MI) have been reported to share similar neural networks. This study investigated the congruency between AO and MI using the eye gaze metrics, dwell time and fixation number. A simple reach-grasp-place arm movement was observed and, in a second condition, imagined where the movement was presented from the first person perspective (1PP) and the third person perspective (3PP). Dwell time and number of fixations were calculated for whole scene and regions of interest (ROIs). For whole scene, no significant differences were found in the number of fixations for condition (AO, MI) or perspective. Dwell time, however, was significantly longer in AO than MI. For ROIs, the number of fixations was significantly greater in 1PP than 3PP. The data provide support for congruence between motor simulation states but also indicate some functional differences. 相似文献

This mixed method study applies components of the theory of planned behavior (Ajzen and Fishbein 1980) to mother-adolescent conflict. We examine if three kinds of beliefs—behavioral, control, and normative—predict patterns of family conflict. Forty mother-adolescent dyads completed an open-ended interview, self-report measures of conflict, and an observational measure of family interaction. Hierarchical multiple regressions revealed that mothers’ and adolescents’ beliefs about the costs and benefits of conflict significantly predicted how they interacted and perceived conflict within dyads. Sex differences and differences between mothers and adolescents were identified. This work contributes to our understanding of the role of both general and specific beliefs in family conflict. 相似文献

Several previous studies have suggested that we may attend only a fixed number of 'objects' at a time. However, whereas findings from two-target experiments suggest that we can attend only one object at a time, other results from object-tracking and enumeration paradigms point instead to a four-object limit. Here, we note that in these previous studies the number of objects covaried with the overall size and complexity of the stimulus, such that apparent one-object or four-object limits in those tasks may reflect changes in the complexity of attended stimuli, rather than the number of objects per se. Accordingly, in the current experiments we employ stimuli in which the number of objects varies, while overall size and complexity are held constant. Using these refined measures of object-based effects, we find no evidence for a one-object or four-object limit on attention. Indeed, we conclude that the number of attended objects does not affect how efficiently we can attend a given stimulus. We propose and test an alternative approach to object-based attention limitations based on within-object and between-object feature-binding mechanisms in human vision. 相似文献

Teenage premarital sexual activity has become an important concern for parents and educators in recent years. Many attempts have been made to address this problem in order to reduce the number of teenage pregnancies and sexually transmitted diseases. The authors review some of those efforts and attempt to identify the approaches that seem to be effective. Implications for research are also presented. 相似文献

This study investigated differences in the phonological knowledge and reading skill of deaf adults using three experimental conditions that tested sensitivity to syllables, rhyme, and phonemes. Analysis of response latencies and accuracy in the three awareness tasks demonstrated that skilled deaf readers had superior phonological awareness skill to that of less-skilled readers and showed less reliance on orthography when making their phonological judgments. Rhyme had greater independent predictive strength than syllable or phoneme awareness for reading comprehension. Phoneme awareness did not contribute independently to either reading comprehension or word reading, but it did independently predict application of grapheme-phoneme correspondences. 相似文献
