Strategic spatial anchoring as cognitive compensation during word categorization in Parkinson’s Disease: Evidence from eye movements
MetadataShow full item record
The association between a word and typical location (e.g., cloud-up) appears to modulate healthy individuals' response times and visual attention. This study examined whether similar effects can be observed in a clinical population characterized by difficulties in both spatial representation and lexical processing. In an eye-tracking experiment, participants categorized spoken words as either up-associated or down-associated. Parkinson's disease patients exhibited a tendency to maintain their visual attention in the upper half of the screen, however, this tendency was significantly lower when participants categorized concepts as down-associated. Instead, the control group showed no preference for either the upper or lower half of the screen. We argue that Parkinson's disease patients present an over-reliance on space during word categorization as a form of cognitive compensation. Such compensation reveals that this clinical population may use spatial anchoring when categorizing words with a spatial association, even in the absence of explicit spatial cues.
