The theory predicts that if attention is overloaded or diverted, features (i.e. colors, contrast, shapes, orientations of line, etc.) of each object would be recombined wrongly (illusory conjunction) and thus subjects sometimes would report the illusory object which is not displayed actually. The results of previous studies, however, were inconsistent since the probability of illusory conjuction was different among subjects. Especially, when some stimuli were presented with additive item which shared the same features as the target stimulus, the distribution of the probability showed the bimodality using the Signal Detection Theory. We tested the three possibilities of the causes of this phenomenon. That is 1) feature conditions (lack, conjuctive, additive), 2) anisotoropy, 3) subject effect measured by VVQ test (Vebalizer Visualizer Questionnaire). The result showed that the discriminability in each stimulus condition did not distribute bimodal. The result also implied that there are some relations between the occurence of the illusory conjunction and VVQ scores.}, pages = {80--88}, title = {Illusory Conjunciton 生起確立の分布に及ぼすいくつかの要因について : 付加特徴の効果,空間異方性,VVQテストとの関連}, volume = {13}, year = {} }
