Figural after-Effects Resulting from Gross Action Patterns: The Amount of Exposure to the Inspection Task and the Duration of the after-Effects

Abstract One hundred and twenty male university students guided themselves, while blindfolded, through curved and straight pathways. Of these 120, 40 subjects moved eight times through curved half-circle pathways, a second 40 traversed them twelve times, while a final 40 moved sixteen times through them. Based upon the percent who reported opposite curvature in a straight test pathway traversed immediately afterward, an intermediate amount of exposure (12 traversals) in the inspection task (the curved pathways) resulted in slightly more sustained after-effects. Theoretical implications relative to Helson's Adaptation Theory are discussed.
