Socially shared perception and metacognition
Perceptual experience provides rational support for actions, beliefs, and intentions. When you see a banana as yellow, that perceptual experience makes it reasonable for you to believe that the banana is yellow. But decades of research show that other people have an implicit impact on individual perception and cognition. This influence even occurs with the mere presence of others: we unconsciously and spontaneously encode others’ perceptual perspectives and shift our frame of reference accordingly. Theories of human perception and attention, however, have been predominantly centred on the solitary mind. What is the epistemic standing of socially influenced perception?
To answer this question, one of the key factors that must be addressed is conscious access. If you are unaware that others distort your perceptual experience, are you responsible for the beliefs and behaviours based on that experience? What is, if any, the epistemic responsibility of other agents in distorting, or aiding, an individual’s perception? Building on current models of perceptual metacognition, the project will (1) develop a principled way to determine experimentally whether social influences on perception are still minimally accessible to consciousness, and (2) examining how these social influences and their metacognitive profile modulate the epistemic role of perceptual experience in justifying actions and beliefs.
Collective perception and the sense of reality
We can differentiate veridical perceptual experiences from imagination and hallucination, because veridical perception comes together with a feeling that we are perceiving the real world: a sense of reality. But what makes an experience feel real? In both analytic and phenomenological philosophy traditions, perceptual social interaction has been considered an important step for the idea of a shared objective reality. However, most philosophical accounts of the sense of reality in perception take an individualistic approach.
The aim of this project is to build on the proposal that we directly perceive the content of another’s perspective, and examine how a sense of reality is constructed through shared perception. I will critically examine the claim that the ability to coordinate my perception to an object together with another individual, goes hand in hand with the ability to experience objects as real, and differentiate them from hallucinations and imagery.
Joint Attention: Perception and Other Minds
From care-giver and infant playing with a toy, to singing duets or playing basketball, we frequently and effortlessly coordinate our attention with others towards a common focus. Joint attention plays a fundamental role in our social lives: it ensures that we refer to the same object, develop a shared language, understand each other and coordinate our actions.
This project aims is to elucidate the relational nature of joint attention, and its functional significance for social cognition, including cases involving different sense modalities and more complex forms of joint activities.
The project's subgoals are to:
- clarify the role of perceptual experience for characterising joint attention;
- propose a functional framework to assess multisensory contributions to establishing and maintaining joint attention;
- test the hypothesis that engaging in joint attention can affect the processing of multisensory information.
