The Aim
The Garner Lab studies how memories and expectations shape perception.
The Impact
Our brains use memories and expectations to interpret what we sense. This is what allows us to react to a siren before we have fully registered the sound. But these same interpretive processes can also misfire, contributing to conditions like anxiety, PTSD, and learning or sensory disorders. By studying how perception works in everyday life, the Garner Lab aims to understand both how the brain makes sense of the world and what happens when that process breaks down.
A Closer Look
TEDx New England talk: How memories shape your reality (September 2024) – video (opens in a new tab)
In this TEDx talk, Aleena Garner explains how memory quietly rewrites incoming sensory signals so that what we see and hear is always filtered through what we already expect. This speaks to the brain’s role as a prediction machine rather than a neutral recorder of the world.
July 2024 Brainfacts.org article: Sound Expectations & Auditory Hallucinations – article (opens in a new tab)
In this article, Garner explains how the brain uses what it has heard before to predict what it will see next, and how a breakdown in that process may underlie the auditory hallucinations experienced by those with schizophrenia.
