We investigated whether prosocial and nonsocial word primes prior to action observation modify subsequent initiation and execution of the observer's own reach-to-grasp actions. Participants observed a model performing exaggeratedly curved (vertical deviation) or natural straight reaches to a vertical dowel and always performed a straight reach to a dowel themselves. Observing curved movements slowed initiation times and increased the vertical deviation of the participants’ movements. Observing curved movements enhanced vertical deviation only in the prosocial word primes condition. We suggest that social context priming can modulate initiation of movement as well as the extent of motor contagion (in this case, the extent of vertical deviation) between model and observer. 相似文献

Contemporary studies in unconscious cognition are essentially founded on dissociation, i.e., on how it dissociates with respect to conscious mental processes and representations. This is claimed to be in so many and diverse ways that one is often lost in dissociation. In order to reduce this state of confusion we here carry out two major tasks: based on the central distinction between cognitive processes and representations, we identify and isolate the main dissociation paradigms; we then critically analyze their key tenets and reported findings. 相似文献

It is assumed that the processing of a prime followed by a mask occurs sequentially in a feedforward manner when the three (initiation, takeover, and independence) criteria outlined by the rapid-chase theory are met. The purpose of the current study was to determine if the processing of the prime and mask fit the predictions of the rapid-chase theory when the prime and mask are presented during an ongoing movement. In two experiments, participants made rapid pointing movements to a target indicated by the mask. In Experiment 1, the prime was presented at movement onset and the prime-mask stimulus onset asynchrony (SOA) was manipulated. In Experiment 2, the prime-mask SOA was constant but the delay between movement and prime onset was manipulated. Although the results support the initiation and takeover criteria, the data did not support the independence criterion. Consequently, the rapid-chase theory does not appear to extend to movement execution. 相似文献

Unconscious thought theory (UTT) suggests that conscious thinking is less effective in complex decision-making than unconscious thinking. However, little research has taken individual differences (e.g., cognitive style) into account. Using an adapted UTT paradigm, the present study compared the performances of individuals with a wholist or an analytic cognitive style in both conscious and unconscious thought conditions. After viewing information regarding four hypothetical phones, participants in the conscious thought condition deliberated for three minutes before rating the phones, while participants in the unconscious thought condition were distracted with a 2-back task for three minutes before rating. The results showed that wholists were equally good at differentiating good and bad phones after conscious or unconscious thought, whereas analytics performed well only when thinking unconsciously. The modulation effect of cognitive style appeared only in conscious thought. Implications for UTT and the understanding of cognitive style are discussed. 相似文献

ABSTRACTThe results of this study confirmed that people react differently to preferred meanings of ambiguous images (to those that will get into consciousness later) and to rejected meanings of ambiguous images (those that will not). We observed a facilitative after-effect of the preferred meaning which was expressed in the positive priming-effect, and the following dynamics of the rejected meaning after-effect: positive priming at small values of SOA (30?ms), negative at bigger SOA values (530?ms) and positive priming at all the following SOA values (1,030, 3,030 and 5,030?ms). These results imply that subliminal perception, as well as supraliminal, is selective. We believe that negative priming for one of the meanings of an ambiguous image presented subliminally might be associated with an unconscious decision as to whether or not a particular stimulus will enter into consciousness, in accordance with the negative choice theory. 相似文献

The dominant theory of what people can learn implicitly is that they learn chunks of adjacent elements in sequences. A type of musical grammar that goes beyond specifying allowable chunks is provided by serialist or 12-tone music. The rules constitute operations over variables and could not be appreciated as such by a system that can only chunk elements together. A series of studies investigated the extent to which people could implicitly (or explicitly) learn the structures of serialist music. We found that people who had no background in atonal music did not learn the structures, but highly selected participants with an interest in atonal music could implicitly learn to detect melodies instantiating the structures. The results have implications for both theorists of implicit learning and composers who may wish to know which structures they put into a piece of music can be appreciated. 相似文献
