There have been 314 post-conviction DNA exonerations, and about 70% of these wrongful convictions were due to witness misidentification. Many factors affect the accuracy of a witness’s testimony, including the concept of “verbal overshadowing,” in which the verbal reporting of a visual memory interferes with the subsequent recognition of the visual stimuli. The present study seeks to replicate Jonathan Schooler’s original findings with regard to this phenomenon (Schooler & Engstler-Schooler, 1990). The first experiment is focused on verbalizing a visual memory that is particularly hard to put into words: the memory of a face. The hypothesis for both the original …

Many developers wish to capitalize on touch-screen technology for developing aids for the blind, particularly by incorporating vibrotactile stimulation to convey patterns on their surfaces, which otherwise are featureless. Our belief is that they will need to take into account basic research on haptic perception in designing these graphics interfaces. We point out constraints and limitations in haptic processing that affect the use of these devices. We also suggest ways to use sound to augment basic information from touch, and we include evaluation data from users of a touch-screen device with vibrotactile and auditory feedback that we have been developing, …
