Is optimism optimal? Functional causes of apparent behavioural biases
Behavioural Processes, 2012We review the use of the terms 'optimism' and 'pessimism' to characterize particular types of behaviour in non-human animals. Animals can certainly behave as though they are optimistic or pessimistic with respect to specific motivations, as documented by an extensive range of examples in the literature.

Biased diffusion in percolation systems: indication of multifractal behaviour
Journal of Physics A: Mathematical and General, 1987The authors study diffusion in percolation systems at criticality in the presence of a constant bias field E. Using the exact enumeration method they show that the mean displacement of a random walker varies as (r(t)) approximately log t/A(E) where A/(E)=In((1+E)/(1-E)) for small E. More generally, diffusion on a given configuration is characterised by

Sex-biased disruptive behaviour in breeding crested penguins
Polar Biology, 2012Colonial breeding is common in seabirds, and may provide individuals with benefits such as increased protection from predators by joint defence, improved information exchange and enhanced access to mates. However, the presence of large numbers of individuals in breeding colonies may also lead to interference, especially where conspecific behaviour ...

The prominence of behavioural biases in eye guidance
Visual Cognition, 2009When attempting to understand where people look during scene perception, researchers typically focus on the relative contributions of low- and high-level cues. Computational models of the contribution of low-level features to fixation selection, with modifications to incorporate top-down sources of information have been abundant in recent research ...

Behavioural Biases and the Pricing-Kernel Puzzle
SSRN Electronic Journal, 2017The pricing-kernel, when estimated from index options, appears to show risk-loving behaviour for small gains and losses. Although this puzzle could be caused by option buyers using subjective probability-weighting, such weighting generates an unrealistically large (and time-varying) risk-premium.
