- Abstract
- Young children show an immature capacity to reason about sources of knowledge, overestimating the knowledge to be gained from looking actions compared to other actions. Recent studies using computer tasks have suggested that this overestimation is not completely overridden when adults reason about the knowledge other people gain from their physical interactions with the world. The aim of the current study was to characterize source of knowledge processing in adults when they have to reason about their own sources of knowledge during on-line physical interactions with the environment. Thirty right-handed healthy volunteers were asked to answer as quickly as possible questions regarding the characteristics of an object placed inside a box. The object changed from trial to trial, and could vary in color (white or green), temperature (cold or warm), and weight (heavy or light). To answer each question, participants could perform one of three actions: 1) looking at the object inside the box (opening the box from one side), 2) touching the object (through a hole on the front of the box), or 3) lifting the object (pulling a string on top of the box). Overt responses were recorded by the experimenter and showed that in the first block of trials, 30% of the participants wrongly choose a looking action to verify non-visual object properties. Such results indicate that the bias to overestimate the knowledge gained from looking occurs even during on-line physical interactions with the environment. Preliminary data from a motion tracking sensor that was attached to each subject’s right index will also be presented and discussed.
