The Effect of Perceptual Learning on Face Recognition in Individuals with Central Vision Loss.

ABSTRACT:

Purpose

To examine whether perceptual learning can improve face discrimination and recognition in older adults with central vision loss.

Methods

Ten participants with age-related macular degeneration (ARMD) received 5 days of training on a face discrimination task (mean age, 78 ± 10 years). We measured the magnitude of improvements (i.e., a reduction in threshold size at which faces were able to be discriminated) and whether they generalized to an untrained face recognition task. Measurements of visual acuity, fixation stability, and preferred retinal locus were taken before and after training to contextualize learning-related effects. The performance of the ARMD training group was compared to nine untrained age-matched controls (8 = ARMD, 1 = juvenile macular degeneration;
