Mixture choice data consist of the joint distribution choices a group agents from collection menus, comprising implied stochastic function plus any cross-menu correlations. When are heterogeneous with respect to both preferences and other aspects cognition, we show that these two determinants behavior identified simultaneously by suitable mixture data. We also demonstrate how this finding can b...

Do we fully understand the structure of the problems we present to our subjects in experiments on animal cognition, and the information required to solve them? While we currently have a good understanding of the behavioural and neurobiological mechanisms underlying associative learning processes, we understand much less about the mechanisms underlying more complex forms of cognition in animals....

Neuroimaging has identified an overlapping network of brain regions whose activity is modulated by mood and cognition. Studies of depressed individuals have shown changes in perception, attention, memory, and executive functions. This suggests that mood has a pervasive effect on cognition. Direct evidence of the effect of sad mood on cognition is surprisingly limited, however. Published studies...

In this chapter, we analyze the relationships between the Internet and its users in terms of situated cognition theory. We first argue that the Internet is a new kind of cognitive ecology, providing almost constant access to a vast amount of digital information that is increasingly more integrated into our cognitive routines. We then briefly introduce situated cognition theory and its species o...

background: the association between helminthic parasitic infection and cognitive function has long been recognized, however there are few reports about giardia lamblia infection. this paper describes a study about the effect of g. lamblia infection on the cognitive function. methods: one hundred thirty two children infected with g. lamblia from robat karim south of western tehran, iran were com...

Organisms across species use the strategy of generating structures in their environment to lower cognitive complexity. Examples include pheromones, markers, color codes, etc. We provide a model of how such structures originate, and present a simulation where organisms with only reactive behavior learn, within their lifetime, to add such structures to their world to lower cognitive load. This im...

A central tenet of evolutionary ethics is that as a result processes, humans tend to respond in certain ways particular moral problems. Various authors have posited “dual-process” conflicts between “fast”, automatic, evolved impulses, and “slower”, controlled, reasoned judgements. In this chapter we argue the sources automatic judgements are diverse, include some intuitive processes (especially...
