dc.description.abstract The present investigation was designed to answer the question of whether or not schizophrenia spectrum members exhibit increased susceptibility to perceptual and conceptual backward masking effects when processing complex stimulus events. Introductory psychology students were screened through the use of the Minnesota Multiphasic Personality Inventory (MMPI) to obtain 3 groups of subjects having inflation-free, 4-9, and 2-7-8 profiles. Immediate memory for pictures was assessed as a function errors in all of the groups for both correct and incorrectof mask type (picture, pattern, and noise), luminance (high vs. low), and mask delay (0 vs. 300 ms). No significant differences were found between the groups in their ability to recognize a picture in the absence of a mask. The frequency of mask target trials was discovered to be nonsignificant. Analysis of subjects’ number of correct target identifications as a function of group, mask type, luminance level and delay of mask revealed significant main effects for luminance and for delay of mask. However, no factor involving the group variable reached statistical significance.
