Abstract

Dimensional interactions of width and orientation stimuli in early visual processing were assessed in a texture-segregation paradigm. The basis for detecting a discrepant quadrant in 6 × 6 arrays of objects was varied in accordance with Garner's Control, Correlated, and Orthogonal conditions. Individual differences as measured by Witkin's Group Embedded Figures Task differentiated performance patterns on the texture-segregation task. Individuals with high scores on the Embedded Figures Test, termed Field-independent, exhibited redundancy gains in the Correlated condition and no interference in the Orthogonal condition whereas those scoring low, termed Field-dependent, demonstrated no redundancy gains and no interference effects. Results support recent findings that individual differences in field dependence-independence are associated with differences in low-level visual mechanisms and suggest that individual differences in attentional flexibility exist in early visual processing.
