Attention shapes visual perception

Visual attention is essential for visual perception. Spatial attention
allows us to grant priority in processing and selectively process
information at a given location. In this talk, I will present empirical
studies:

(1) investigating how endogenous (voluntary) and exogenous (involuntary)
covert attention improve contrast sensitivity at attended locations and
have concurrent costs at unattended locations;

(2) testing predictions of a normalization model of attention; (3)

The Evolution of Punishment

Punishment involves paying a cost to harm another individual and is thought to be a key mechanism that promotes cooperation. Nevertheless, it is not clear (1) whether punishment has the effect of converting cheats into cooperators or (2) how punishment can be favoured by selection, given that it involves costs to punishers. Here, I will use the cleaner fish-client mutualism as a model species to show that punishment does indeed promote cooperation in some contexts.

Computational Neuroimaging of Human Auditory Cortex

Just by listening, humans can determine who is talking to them, whether a window in their house is open or shut, or what their child dropped on the floor in the next room. This ability to derive information from sound is enabled by a cascade of neuronal processing stages that transform the sound waveform entering the ear into cortical representations that are presumed to make behaviorally important sound properties explicit.
