The Influence of Interference Items Features on Semantic Effects in Picture-Word Interference Paradigm
Ren Guiqi · Journal of Liaoning Normal University · 2014
A picture-word interference paradigm was used to investigate the interference effects of semantic types and word frequency.Eye tracker was used to investigate the picture-word interference effects when subjects were asked to finish a semantic task.Three eye movement index such as total fixation durations, gazing point numbers and regional time percent is chosen to conduct the research.The results showed that:(1)there were frequency effects and semantic effects among interference items in picture-word paradigm;subjects made more mistakes for high frequency words than that for low frequency words,which is due to the semantic association between the interference items and target picture being affected by high frequency interference items.(2)More fixation durations were spent in inconsistent conditions than that in consistent conditions,which is mainly due to stimulation speed differences of two kinds of inteference items.(3)word frequency and semantic type both affected semantic effects;(4)the feature of interference items which were located in the center of the picture should not be ignored in picture-word interference paradigm.
