Previous studies have shown that fixations on familiar stimuli tend to be longer than on unfamiliar stimuli, theorized to be a result of retrieval of information from memory. We hypothesize that extended fixations are due to a lesser need to explore an already familiar stimulus. Participant's gaze was tracked as they tried to encode or retrieve a…

Learning spatial layouts and navigating through them rely not simply on sight but rather on multisensory processes, including touch. Digital haptics based on ultrasounds are effective for creating and manipulating mental images of individual objects in sighted and visually impaired participants. Here, we tested if this extends to scenes and…

Memory is expressed in multiple functionally and anatomically distinct systems that interact over the course of learning and during the retrieval of information about the world. One method to determine the kind of memory representation (episodic and/or procedural) guiding behavior is to look at the expression of expectations (i.e., predictions) in…

Research on attention allocation to social and non-social stimuli in autism spectrum disorder (ASD) has produced mixed results, with some studies suggesting that attention allocation is atypical in ASD (e.g., Klin, Jones, Schultz, Vokmar, & Cohen, 2002) and others finding no significant differences in attention allocation patterns when…

Fifteen stutterers (aged 5-16) were treated using graded airflow, tension/relaxation, and electromyographic biofeedback to reduce stuttering frequency. In a second study, addition of a discriminative stimulus control procedure to maintain fluency made the treatment program more effective than the first study and achieved a level of <1% stuttered…
