Half of the 36subjects received the two figures, and the other half were presented two sounds during habituation session. After the session, subjects were assigned to one of the following three groups during the test session: The Key-Press(KP) group, in which the subjects were required to press a key to the offset of one (test stimulus) of the two stimuli; The Perceptual-Judgement (PJ) group which estimated the perceived duration of the test stimulus; The Neutral-Instruction (NI) group which was asked to do nothing to the stimulus presentations. Results are as follows: (1) The KP and the PJ groups indicated a significant increase of the EDR to the test stimulus (selective OR), but not to the non-test stimulus when compared to the NI group. (2) The effects of overt "key press" and covert "perceptual judgement" appeared equally on the EDR to the test stimulus. These results suggest the occurrence of selective OR to the significant stimulus under the unimodal presentation.}, pages = {103--112}, title = {定位反応に及ぼす内示反応と外示反応の課題教示の効果―単一モダリティでの刺激提示事態について―}, volume = {37}, year = {1991} }
