Don’t be fooled! Attentional responses to social cues in a face-to-face and video magic trick reveals greater top-down control for overt than covert attention

Cognition, vol. 146, p. 136-142, 2016

People’s attention is oriented towards faces, but the extent to which these social attention effects are under top down control is more ambiguous. Our first aim was to measure and compare, in real life and in the lab, people’s top-down control over overt and covert shifts in reflexive social attention to the face of another. We employed a magic trick in which the magician used social cues (i.e. asking a question whilst establishing eye contact) to misdirect attention towards his face, and thus preventing participants from noticing a visible colour change to a playing card. Our results show that overall people spend more time looking at the magician’s face when he is seen on video than in reality. Additionally, although most participants looked at the magician’s face when misdirected, this tendency to look at the face was modulated by instruction (i.e., “keep your attention on the cards”), and therefore, by top down control. Moreover, while the card’s colour change was fully visible, the majority of participants failed to notice the change, and critically, change detection (our measure of covert attention) was not affected by where people looked (overt attention). We conclude that there is a tendency to shift overt and covert attention reflexively to faces, but that people exert more top down control over this overt shift in attention. These finding are discussed within a new framework that focuses on the role of eye movements as an attentional process as well as a form of non-verbal communication.

A psychologically-based taxonomy of misdirection

Kuhn, Gustav ; Caffaratti, Hugo A. ; Teszka, Robert ; Rensink, Ronald A.
Frontiers in Psychology, vol. 5, art. 1392, 14 pages, 2014

Magicians use misdirection to prevent you from realizing the methods used to create a magical effect, thereby allowing you to experience an apparently impossible event. Magicians have acquired much knowledge about misdirection, and have suggested several taxonomies of misdirection. These describe many of the fundamental principles in misdirection, focusing on how misdirection is achieved by magicians. In this article we review the strengths and weaknesses of past taxonomies, and argue that a more natural way of making sense of misdirection is to focus on the perceptual and cognitive mechanisms involved. Our psychologically-based taxonomy has three basic categories, corresponding to the types of psychological mechanisms affected: perception, memory, and reasoning. Each of these categories is then divided into subcategories based on the mechanisms that control these effects. This new taxonomy can help organize magicians' knowledge of misdirection in a meaningful way, and facilitate the dialog between magicians and scientists.
