Social perception and the action-observation method

James T. Enns,

Professor and Distinguished University Scholar, University of British Columbia

Everyday human interaction involves inferring people’s mental states, their intentions and future actions, by way of facial expression, body posture, eye gaze, and limb movements. I will describe an iterative method for studying action production and action perception, under the assumption that observers form predictive simulations to guide their behavior. Some studies involve single actors performing tasks (e.g., the mental effort of visual search, the kinematics of reaching, emotion perception while self-monitoring, gaze aversion during conversation). Other studies involve actors working in collaboration (e.g., the perception of jazz duets, collaborative visual search, moving furniture, joint exercise).

The Role of Brain Oscillations in the Attentional Blink

Kim Shapiro

Professor, Chair of Cognitive Neuroscience, Centre for Human Brain Health and School of Psychology, University of Birmingham

In recent years there has been an increasing drive to understand the role played by brain oscillations in human cognition. Neural oscillations are a plausible mechanism by which distributed brain areas can communicate in real time to support the spectrum of cognitive activity from stimulus representation to decision making. My talk will focus on the role played by oscillations in different frequency bands to facilitate attention by examining the phenomenon of the attentional blink. Understanding the role of brain oscillations will be made increasingly possible by advances in high-density EEG, MEG, transcranial electrical stimulation, and electrocorticography.

Knowing what’s real: The role of Attention in Banknote Authentication

Jane E. Raymond

Professor (Emeritus), University of Birmingham

How do people know the difference between genuine objects and counterfeit? What role does visual attention play in authentication judgements? Recent studies from my lab on how consumers authenticate banknotes have shed light on these questions. We found that counterfeit is generally detected very quickly by the brain’s sensory processes, but slower more cognitive processes involved in recognition of images, e.g., a portrait on a banknote, often override the initial impression that a banknote is fake. We also report that special print features that provide clear visual signals of authenticity can dramatically improve counterfeit detection but only if these features quickly capture fixation and provide simple, obvious cues that cannot be easily reproduced. These and other related findings point to the general principle that authentication is based on object features that are tangential to object categorisation but are themselves easily identified. Such findings are currently being used to improve the design of banknotes and other products to improve security for consumers.
