Investigators of microelectronic visual prosthesis devices have found that some aspects of
vision can be restored in the form of spots of light in the visual field, so-called “phosphenes” …

The structure of the human face allows it to signal a wide range of useful information about a
person's gender, identity, mood, etc. We show empirically that facial identity information is …

We examined the amount of practice needed to improve performance on 10-AFC face-and
texture identification tasks. On Day 1, subjects were grouped by amount of practice: a control …

Background In this study, we quantified age-related changes in the time-course of face
processing by means of an innovative single-trial ERP approach. Unlike analyses used in …

We trained subjects to identify either upright or inverted faces in a 10AFC task and
measured performance subsequently in four conditions: same-and different-upright faces …

The type of visual information needed for categorizing faces and nonface objects was
investigated by manipulating spatial frequency scales available in the image during a …

Five minutes of processing the local features of a Navon letter causes a detriment in
subsequent face-recognition performance (Macrae & Lewis, 2002). We hypothesize a …

Letters are broadband visual stimuli with information useful for discrimination over a wide
range of spatial frequencies. Yet, recent evidence suggests that observers use only a single …

When the size of a letter stimulus is near the visual acuity limit of a human subject, details of
the stimulus become unavailable due to ocular optical and neural filtering. In this study we …

We examined whether familiarity with a face influences the spatial frequencies (SFs)
required for face matching. Using the psychophysical method of constant stimuli and a 3AFC …
