Summary
Word and nonword representations are spatial. Experiments show word superiority and spatial compatibility effects, with vertical word presentation leading to vertical arrangement, demonstrating flexible spatial representation.
Area of Science:
- Cognitive Psychology
- Psycholinguistics
- Human Information Processing
Background:
- Investigating the nature of word representations is crucial for understanding reading and language processing.
- Previous research suggests word representations are unitary, but their spatial characteristics remain debated.
Purpose of the Study:
- To determine if word and nonword representations possess spatial properties.
- To examine the influence of stimulus orientation on the spatial layout of word representations.
- To investigate the interplay between word recognition and spatial processing.
Main Methods:
- Participants performed letter search tasks in horizontally and vertically presented words and nonwords.
- Response times were measured for target letters at different positions.
- Stimulus-response compatibility (Simon effect) and word superiority effects were analyzed.
Main Results:
- Faster responses to targets in words than nonwords (word-superiority effect).
- Faster responses for compatible stimulus-response pairings (Simon effect).
- Left-side targets were responded to faster than right-side targets in nonwords (left-right scanning effect).
- Vertical word presentation eliminated spatial compatibility effects, suggesting vertical arrangement.
Conclusions:
- Word and nonword representations exhibit spatial characteristics.
- The spatial layout of word representations adapts to stimulus orientation, aligning horizontally for horizontal stimuli and vertically for vertical stimuli.
