9:30-10:30 Paper Session II ( Moderator: Sadie Emery, Clinical Graduate Program, Texas Tech University)

9:30-9:50 Characteristics of Layout Representations ALICIA O. BURRIS & CARMELA V. GOTTESMAN, University of Oklahoma (Faculty Sponsor: CARMELA V. GOTTESMAN, University of Oklahoma) Two experiments examined layout representations’ sensitivity to view expanse and view angle. In both experiments participants saw a prime, a target containing 2 spots, and were asked to determine the closest spot. Primes in the first experiment included: same view, closer-up view, and wider-angle view. Facilitation occurred for all primes, but was smaller for close-ups. Primes in the second experiment included 0°, 30°, 60°, or 90° view angles. Facilitation occurred only for small angle differences.

9:50-10:10 Repetition Priming Components in Picture Naming MARY L. JONES, University of Texas at El Paso (Faculty Sponsor: WENDY S. FRANCIS, University of Texas at El Paso) Two parallel experiments in English and Spanish examined repetition priming in different components of picture naming. Picture categorization was used to prime picture identification processes, and naming a different exemplar was used to prime word retrieval processes. Both tasks elicited priming in picture naming, and these effects were independent, suggesting that picture identification and word retrieval components of picture naming are independent and sequential.

10:10-10:30 Iconic Memory Effects on Object Substitution Masking MICHAEL W. MEBANE, Texas Tech University (Faculty Sponsor: WILLIAM S. MAKI, Texas Tech University) Object substitution occurs when four small dots surrounding a visual target drastically impair identification of the target when the dots remain visible after the target disappears. Previous studies show the mask does not have to be over the target to mask the target. Our results show that when the mask is not presented over the target, a large number of the errors come from the letter under the mask, suggesting a reinterpretation of previous studies.
