An Investigation Of Peripheral Localization Errors In Older Adults, Eric Stephens
An Investigation Of Peripheral Localization Errors In Older Adults, Eric Stephens
Masters Theses & Specialist Projects
In a typical useful field of view (UFOV) paradigm, an observer must correctly identify a center target while simultaneously localizing a peripheral target. Previous research has shown that many older adults have difficulty locating the peripheral target in the UFOV paradigm when compared to younger adults (Sekuler & Ball, 1986; Scialfa, Kline, & Lyman, 1987; Ball, Beard, Roenker, Miller, & Griggs, 1988; Ball, Roenker, & Bruni, 1990; Scialfa, Thomas, & Joffe, 1994). However, the reason for this difficulty is not clearly understood. The purpose of this study was to test two potential explanations for the difficulty that some older adults …
The Effects Of Practice On Stroop Inhibition: A Process Dissociation Approach, Emily Patterson
The Effects Of Practice On Stroop Inhibition: A Process Dissociation Approach, Emily Patterson
Masters Theses & Specialist Projects
Two studies were performed to investigate the effects of age and practice on Stroop inhibition. The first experiment examined the influence of age on the ability to ignore the meaning of words on Stroop items. Fifteen younger and 15 older adults were asked to name the color of congruent, incongruent, and control items appearing on a computer screen. Participants' interference and facilitation scores, error rates, and color and word process dissociation estimates were computed. The results indicate that older adults experienced more interference and facilitation than the younger adults and produced more errors than the younger adults on items where …
