The impact of novel labels on visual processing was investigated across two experiments with infants aged between 9 and 21 months. Infants viewed pairs of images across a series of preferential looking trials. On each trial, one image was novel, and the other image had previously been viewed by the infant. Some infants viewed images in silence; other infants viewed images accompanied by novel labels. The pattern of fixations both across and within trials revealed that infants in the labelling condition took longer to develop a novelty preference than infants in the silent condition. Our findings contrast with prior research by Robinson and Sloutsky (e.g., Robinson & Sloutsky, 2007a ; Sloutsky & Robinson, 2008 ) who found that novel labels did not disrupt visual processing for infants aged over a year. Provided that overall task demands are sufficiently high, it appears that labels can disrupt visual processing for infants during the developmental period of establishing a lexicon. The results suggest that when infants are processing labels and objects, attentional resources are shared across modalities. 相似文献

The lack of an adequate theory of reversible perspective is largely attributable to the haphazard methodology adopted by many workers in this area of research. After more than 60 years, no standard experimental procedure has evolved, and the comparison of results from different studies is difficult. Some representative experiments are reviewed in terms of the temporal, stimulus, and procedural factors involved. It is suggested that the general use of the reversal rate measure is the major single barrier to progress, and that a continuous recording method be adopted in future experimentation. 相似文献
