摘要: Determination of a direction travel is necessary component successful navigation, and various species appear to use the geometric shape (global cues) an environment determine direction. Yet, debate remains concerning which objective parameter responsible for spatial reorientation via global cues. For example, principal axis space, runs through centroid approximate length medial trunk branch system that fills shape, have each been suggested as basis explain reorientation. As principal- medial-axis accounts substantial theoretical implications regarding nature perception, memory, underlying psychological representations it appears critical empirically differentiate between these accounts. The present experiment explicitly placed predictions from medial-axis-based in conflict diagnostic purposes. We used standard paradigm human participants first reoriented rectangular environment; subsequent testing I-shaped enclosure allowed dissociation or show was consistent with principal-axis account inconsistent account. suggest relatively simple efficient way establish directionality would be advantageous over more complex less (PsycINFO Database Record
