1. Defensive coloration: some things we know, and some things we’d like to know

Nick SCOTT-SAMUEL (Psychological Science, University of Bristol)

Over the last decade or so, there has been an explosion of interest in the principles that might underlie camouflage: how can one prevent or disrupt the detection, identification, selection or targeting of a prey item? These sorts of question are best addressed from an interdisciplinary perspective, drawing on the knowledge of biologists and psychologists amongst others. I will give an overview of what we know so far, with particular reference to research from CamoLab (www.camolab.com), and then talk about some outstanding issues, in particular attempts to categorise and quantify different camouflage strategies.

2. Effects of perceptual grouping in the brain processing of sounds

Kentaro ONO (Brain, Mind, and KANSEI research center, Hiroshima University)

What is perceptual grouping? Perceptual grouping occurs when we are perceptually put parts together into a whole. Auditory inputs are a mixture of sounds produced by several simultaneous sources. However, we rarely perceive these sounds as incomprehensible noise. While psychological studies have found several principles for perceptual grouping, neural correlates of perceptual grouping remain unclear. Here, I shortly review some neuroimaging studies of perceptual grouping and introduce our studies that have shown neurophysiological correlates of it.
