Michael S. Goodman ’74 Memorial Seminar Series. Perception & Action Seminar Series. Speaker: Zsuzsa Kaldy, UMass Boston. Title: What makes infants’ working memory work? Abstract: Visual Working Memory (VWM) for objects and their locations underlies what is where is paramount. We developed a novel Delayed Match Retrieval paradigm to test infants’ VWM capacity for object/location bindings - what is where - that is based on anticipatory gaze responses. Compared to Violation-of-Expectation paradigms that measure passive gaze responses to novelty, our paradigm presents a more challenging, but more ecologically relevant test of VWM, as it measures the ability to use remembered information to make predictions. I will present results from a series of studies with infants between 7 and 30 months of age, tracing the development of information maintenance and updating in VWM. In the second part of the talk I will present our findings using pupillometry in this task. The task-evoked pupil response (TEPR) has long been taken as a sensitive, real-time, involuntary measure of focused attention in adults. We found that the magnitude of the TEPR during memory encoding predicted VWM performance in infants. Pupillometry provides an exciting new way to investigate the interactions between infants’ attentive states and their VWM capacity.
