Are experience-dependent eye movements determined by implicit or explicit memory processes?

Experience-dependent eye movements reflect hippocampus-dependent (aware) memory.

We investigated the relationship between experience-dependent eye movements, hippocampus-dependent memory, and aware memory. We measured eye movements in young adults, older adults, and memory-impaired patients with damage to the medial temporal lobe as they viewed 120 novel scenes and 120 previously viewed scenes. Participants indicated if each scene was old or new and also gave a confidence r...

Experience-dependent eye movements, awareness, and hippocampus-dependent memory.

We asked what kind of memory is operating when eye movements change as the result of experience. Participants viewed scenes that were either novel, repeated, or manipulated (i.e., a change was introduced in one region of the scene). Eye movements differed depending on the past viewing history of each scene. Participants made fewer fixations and sampled fewer regions when scenes were repeated th...

Implicit and Explicit Processes

Eye Movements Index Implicit Memory Expression in Fear Conditioning

The role of contingency awareness in simple associative learning experiments with human participants is currently debated. Since prior work suggests that eye movements can index mnemonic processes that occur without awareness, we used eye tracking to better understand the role of awareness in learning aversive Pavlovian conditioning. A complex real-world scene containing four embedded household...

Explicit, Neutral, or Implicit

Social groups have different rules and preferences for what they consider acceptable behavior and a social behavior that is favorable in a certain cultural context may be unacceptable in another. In this study, we evaluate the effects of robot communication style on how participants from two distinct cultures (Indian and American) perceive them; the robots use or violate cultural norms. We recr...
