Evidence for carcass access times and levels of early hominid mobility is synthesized using studies of carnivore ethology and theories of interspecific competition to arrive at tentative conclusions about the organization of Plio-Pleistocene hominid foraging groups. The model presented suggests that group foraging tactics, in combination with high mobility, are central to successful confrontati...

Although the title of Cullen's book is Deleuze and Ethology, author does not focus on passages in which Gilles discusses ethology or animals. Cullen even quote Deleuze's valuable definition as “the study . capacities for affecting being affected that characterize each thing.” Instead, tries to construct a philosophical his own with reference works cinema, which, argues, allowed philosopher “to ...

A plethora of words are used to describe the spectrum of human emotions, but how many distinct emotions exist, and how do they interact? Over the past few decades, several theories of emotion have been proposed, each founded upon a set of basic emotions, and each supported by an extensive variety of research including studies in facial expression, ethology, neurology and physiology. Here we pro...

Studies of attention, often conducted in artificial laboratory experiments, may have limited validity when performance in the natural world is considered. For instance, for over two decades investigations of "reflexive" and "volitional" attention have tended to be grounded in methodologies that do not capture the demands of attention in everyday life. Recent studies suggest these laboratory inv...

Ethologists and others studying animal behavior in a "cognitive" spirit are in need of a descriptive language and method that are neither anachronistically bound by behaviorist scruples nor prematurely committed to particular "information-processing models. "Just such an interim descriptive method can be found in intentional system theory. The use of intentional system theory is illustrated wit...

For the past two decades, it has widely been assumed by linguists that there is a single computational operation, Merge, which is unique to language, distinguishing it from other cognitive domains. The intention of this paper is to progress the discussion of language evolution in two ways: (i) survey what the ethological record reveals about the uniqueness of the human computational system, and...

IN A SEMINAL PAPER WRITTEN FIVE DECADES AGO, CRONBACH DISCUSSED THE TWO HIGHLY DISTINCT APPROACHES TO SCIENTIFIC PSYCHOLOGY: experimental and correlational. Today, although these two approaches are fruitfully implemented and embraced across some fields of psychology, this synergy is largely absent from other areas, such as in the study of learning and behavior. Both Tolman and Hull, in a rare c...
