Lab News

At the Memory and Perception of Speech (MAPS) Lab, we broadly investigate how learning and memory support our perception and production of speech.

Our current projects fall into one of three areas:

Memory consolidation of perceptual learning

We are conducting a series of studies into the effects of post-training wake/sleep on the perception and production of newly learned speech contrasts. We combine behavioral methods with actigraphy/sleep polysomnography, and neuroimaging (fMRI, EEG/ERP) techniques, in order to discover the time course for establishing speech sound and speech motor representations. We are interested in how this occurs in individuals with typical language, and also where this process breaks down in individuals with idiopathic speech and language disorders.

Division of labor between memory systems during perceptual learning

Several of our projects focus on defining the separable contributions of the declarative and procedural memory systems to perceptual learning. As declarative and procedural memory are thought to undergo different consolidation processes, our emerging framework for the time course of speech learning is informed by this division of labor. This line of work allows us to ask if the differences in perceptual ability in disordered populations (e.g. developmental language disorder, dyslexia) are attributable to weaknesses in a specific memory system.

Time-of-day effects on perceptual learning

We are launching a new series of studies into how the time of day informs the strategy that people use to learn new perceptual categories. We will examine how the “optimal” time of day of learning differs across individuals at different stages of adolescence, as young adults undergo drastic changes to their chronotype.
