Cross-Modal Attention Influences Auditory Contrast Sensitivity: Decreasing Visual Load Improves Auditory Thresholds For Amplitude- And Frequency-Modulated Sounds, Vivian M. Ciaramitaro, Hiu Mei Chow, Luke G. Eglington
Dartmouth Scholarship
We used a cross-modal dual task to examine how changing visual-task demands influenced auditory processing, namely auditory thresholds for amplitude- and frequency-modulated sounds. Observers had to attend to two consecutive intervals of sounds and report which interval contained the auditory stimulus that was modulated in amplitude (Experiment 1) or frequency (Experiment 2). During auditory-stimulus presentation, observers simultaneously attended to a rapid sequential visual presentation—two consecutive intervals of streams of visual letters—and had to report which interval contained a particular color (low load, demanding less attentional resources) or, in separate blocks of trials, which interval contained more of a target letter …

Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng
Dartmouth Scholarship
Abstract Bruce and Young (1986) proposed a model for face processing that begins with structural encoding, followed by a split into two processing streams: one for the dynamic aspects of the face (e.g., facial expressions of emotion) and the other for the invariant aspects of the face (e.g., gender, identity). Yet how this is accomplished remains unclear. Here, we took a psychophysical approach using contrast negation to test the Bruce and Young model. Previous research suggests that contrast negation impairs processing of invariant features (e.g., gender) but not dynamic features (e.g., expression). In our first experiment, participants discriminated differences in …
