This task is an auditory task designed to measure roving intensity perception and was also adapted from Goswami et al. (2011). Subjects hear 2 stimuli and are asked to indicate which had a softer rise. Stimulus onset difference (i.e. time it takes for stimulus to reach full intensity) begins at 278 ms and changes adaptively […]

Distorted Tunes
The distorted tunes task is an auditory task designed to measure pitch perception (Drayna et al., 2001). Subjects hear short clips of tonal melodies and are asked to indicate whether the tune sounded correctly or incorrectly, with wrong notes in them, and whether or not the tune was familiar to them. Stimuli include tonal representations […]
Tone Matching Task
The tone matching task is designed to measure pitch perception. Subjects are presented with pairs of 100 ms tones with 500 ms inter-tone intervals and are asked to indicate whether they sounded the same or different. In order to minimize learning effects, 3 different base tones are used: 500, 1000, or 2000 Hz. Half the […]
Loneliness, Social Connectedness, and Isolation
Basic Research Questions 1. Do individuals with schizophrenia have intact motivation to interact with others? 2. How does social communication relate to loneliness, desire for social connectedness, and actual isolation in both a healthy population and in schizophrenia? 3. How do these measures relate to clinical outcome? Humans have evolved highly complex social cognitive and […]
Rhythm and Amusia in Schizophrenia
Basic Research Questions 1. Do schizophrenia patients’ rhythmic performances vary in the presence of tonal changes within rhythmic sequences? 2. Would such rhythmic performance variations themselves vary by the subjects’ pitch perception acuity? 3. Does rhythmic performance contribute to schizophrenia dysprosodia? Perceiving social intent via vocal intonation (prosody) is profoundly impaired in schizophrenia. Recent studies […]
Prosody-Centric Neuropsychological Connectome
Basic Research Questions 1. How do deficits in auditory and language abilities relate to prosody perception across different diagnoses? 2. Which neuropathic mechanisms impair prosodic perception in schizophrenia and how are these different from other diagnoses? 3. What are the optimal targets for treatment interventions to improve social communication impairments? Dysprodia, which is impairment in […]
