Trimmer P, McNamara J, Houston A, Marshall J
J Theor Biol
. 2012 May;
302:39-52.
PMID: 22619751
A fundamental question relating to animal behaviour is how animals learn; in particular, how they come to associate stimuli with rewards. Numerous empirical findings can be explained by assuming that...

Biol Lett
. 2012 Feb;
8(4):516-9.
PMID: 22357935
We investigate the optimal behaviour of an organism that is unable to obtain a reliable estimate of its mortality risk. In this case, natural selection will shape behaviour to be...

Behav Processes
. 2011 Nov;
89(2):172-8.
PMID: 22085791
We 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...

Anim Cogn
. 2011 Mar;
14(4):465-76.
PMID: 21360119
Animals (including humans) often face circumstances in which the best choice of action is not certain. Environmental cues may be ambiguous, and choices may be risky. This paper reviews the...

McNamara J, Trimmer P, Eriksson A, Marshall J, Houston A
Ecol Lett
. 2010 Nov;
14(1):58-62.
PMID: 21070564
We propose operational definitions of reproductive optimism and pessimism; optimism involves behaving in a way that gives too much weight (in terms of producing surviving offspring) to positive events, pessimism...

Trimmer P, Houston A, Marshall J, Bogacz R, Paul E, Mendl M, et al.
Proc Biol Sci
. 2008 Jul;
275(1649):2353-61.
PMID: 18611852
Empirical findings suggest that the mammalian brain has two decision-making systems that act at different speeds. We represent the faster system using standard signal detection theory. We represent the slower...
