| 内容記述 | 4つの実験によって,2種類の要素を数百個集めて構成した対象を短時間提示した場合,その構成比率を正確に判断することができるか否かを検討した.実験1では,3つ刺激提示時問を設定して,瞬時に全体を見て要素の構成比率を判断できるか否かを調べた.全体的には,0.5秒,1秒,2秒の各提示時問とも各提示比率において比較的に正確な判断がなされており,知覚の初期段階で比率判断を行うプロセスが機能することが示唆された.実験2では,△と○,□と○いう構成要素を組合せた刺激を用いて,要素の大きさが刺激の比率判断に及ぼす影響を検討した.□と○を対比させた場合には口が過大評価され,△と○を対比させた場合には,構成比率50%を境として,それ以下の比率では△が過大に,それ以上では過小に評価された.実験3では,要素の色特性が刺激の比率判断に及ぼす影響を検討した.赤と白あるいは青と白で刺激を構成した場合,赤及び青の構成比率が過大評価された.ただし,赤と青を対比させた場合は,比較的に提示比率と一致した評価がなされた.実験4では,大きさ(△と□)と色(赤と青)の2つの視覚的特徴を同時に組合せた4種類の要素と白○を対として,それらの特性が比率判断にどのような影響を及ぼすかを調べた.赤△と青△を白○に対比させた場合には,赤□や青□が過大評価され,赤△と青△を白○と対比させた場合には,提示比率に近い比率判断がなされた.これらの結果から,一般に要素の大きさが大きいほど比率は過大に評価され,有彩色の要素は無彩色のものに比べて過大評価されることが分かった.ただし,視覚的特徴を複合させた要素を用いた場合には,何らかの相互作用が働き,提示比率に接近した比率判断を導く方向に作用した. | |||||

| 内容記述 | Four experiments were conducted in order to explore the ability to judge correctly a component. ratio of briefly presented stimulus where several hundreds of components were arranged randomly but divided into two groups by visual features. In Experiment 1, three duration (0.5s, 1s, 2s) for presenting stimulus were tentatively used. The stimulus consisted of two digits, 0 and 1. Component ratios were varied from 10% to 90 % among trials. For almost all presented component ratios, the observers could make relatively precise judgements of component, rat in. The result suggested that early visual information was available in the judgement under these conditions. In Experiment 2 the effects of component size on the ratio judgement were tested. Two combinations of components were used; white filled triangles versus white filled circles and white filled squares versus white filled circles. A square was larger than a triangle. A circle was intermediate between them. Ratio judgements of squares were overestimated for almost all presented component ratios. Whilst ratio judgements of triangles were overestimated where the presented ratio of triangles was under 50%, they were underestimated in the condition that presented ratio of triangles was over 50%. In Experiment 3, we investigated whether the color of components affected ratio judgement. Generally speaking, red is perceived expanding but blue shrinking. Three combinations of color were used; red versus white, blue versus white, and red versus blue. The shape of all components was identical circular. Both blue and red were overestimated against white. On the other hand, the ratio judgements were almost precise in comparisons between red and blue. In Experiment 4, stimulus was specified not by a single feature but by a conjunction of size, shape and color. The shape of component to judge was either a triangle or square, the color of which was either red or blue. The other component was a white circle. Observers judged the ratio of triangle and square. Whilst judgement ratios of square were overestimated in both color conditions, judgement ratios of triangle corresponded fairy accurately to the presented component ratios. Results showed the ratio judgements of large and chromatic components were overestimated. Furthermore an interaction of the two factors was discussed. | |||||
