Abstract:
Objective To investigate how target position and observer's heading affect spatial direction judgement (object locating judgement vs. orienting judgement). Methods Based on visual spatial scene and spatial memory, localization judgement and orientation judgement were used as tasks in four subjects-within experiments respectively. The data of response time were collected as the main dependent variables, and the total, 80 subjects (40 female), participated in the study. Results 1) 0? (front) and 180? (back) advantage effect, north advantage effect (expect for Exp.3), and cardinal direction-R90? position advantage effect were significant; 2) There was no significant difference on response time between Exp.1 and 2, and between Exp.3 and 4; no significant difference on time used for location was found between Exp.3 and 4, but each of them was longer than its corresponding response time for judgement task. Conclusion The effect modes of heading and target position are all consistent between the two types of spatial direction judgements, and the effect modes will not be changed according to differences in information medium and processing.
