刺激の位置を含む複数属性と反応のマッピング学習

Location is considered to play a unique role in object perception, such that focusing attention on an object location combines features of various attributes. However, whether location plays a unique role in visuomotor mapping is unclear. Therefore, we compared stimulus location with other visual features in a multi-attribute stimulus-response mapping learning task. Participants were required to learn the mapping of four sets of stimuli to four response keys. Four objects made by combining two colors and two shapes appeared left or right to the center of the display. These eight stimuli were categorized into four sets: identical color and shape, identical shape and location, identical color and location, and a non-identical feature set. Consequently, participants could learn to map combinations of location and other features to responses, though it was relatively difficult to learn, suggesting that location and other features are combined equivalently in the visuomotor mapping.
