Despite the fact that the role of learning is recognised in empirical and theoretical work on sense of agency , the nature of this learning has, rather surprisingly, received little attention. In the present study we consider the contribution of associative mechanisms to SoA. SoA can be measured quantitatively as a temporal linkage between voluntary actions and their external effects. Using an outcome blocking procedure, it was shown that training action–outcome associations under conditions of increased surprise augmented this temporal linkage. (...) Moreover, these effects of surprise were correlated with schizotypy scores, suggesting that individual differences in higher level experiences are related to associative learning and to its impact on SoA. These results are discussed in terms of models of SoA, and our understanding of disrupted SoA in certain disorders. (shrink)

Although psychologists study both the objective (behavior) and the subjective (phenomenology) components of cognition, we argue that an overemphasis on the subjective drives a wedge between psychology and other closely related scientific disciplines, such as comparative studies of cognition and artificial intelligence. This wedge is particularly apparent in contemporary studies of episodic recollection and future planning, two related abilities that many have assumed to be unique to humans. We shall challenge this doctrine. To do so, we shall adopt an ethological (...) approach to comparative cognition and this necessitates two requirements. The first is that memory and planning need to be characterized in terms of objectively defined properties as opposed to purely phenomenological ones; the ability to remember what happened, where, and how long ago is a critical behavioral criterion for episodic memory. The second requirement is the identification of an ethological context in which these memories would confer a selective advantage. As a consequence, we turn this debate into an empirical evaluation in nonlinguistic animals and one embodied in synthetic creatures. Indeed, our behavioral conception of flexibly deployable information about “what, where, and when” has so far supported a comparative cognition in animals as diverse as corvids and primates. We argue that this approach may clarify and challenge ideas that have been based solely on research with human subjects, without the need to be constrained by phenomenological assumptions based on human‐centric ways of thinking.

In Thucydides' account of Melesander's expedition with six ships to Caria and Lycia there appears to me to be a difficulty which is universally ignored by commentators and fudged by translators. Thucydides describes the purpose of the expedition.

Responding to Allen and Bekoff's (this issue) critique of Heyes and Dickinson's (1990) analysis of the intentionality of animal action, we reiterate that our approach does not assume that a hypothesis can be definitively falsified by the results of a single experiment, and argue that the evolutionary analysis favoured by Allen and Bekoff insulates intentional accounts of animal behaviour from rejection in the usual‘holistic’process of scientific evaluation. Specifically, we present data showing that the maintenance of behaviour on an omission schedule (...) cannot be construed as rational because on these schedules it is reward for withdrawal that restores approach. In addition, we argue that, since behaviour can be affected by the non‐intentional properties of representations such as search images and cognitive maps, whether or not these representations have intentional properties can be assessed empirically only through research on instrumental behaviour.

Although the mental time travel (MTT) hypothesis provides a rich, conceptual framework, the absence of clear, empirically tractable, behavioural criteria for determining the capacity for MTT restricts its usefulness in comparative research. Examples of empirical criteria for evaluating MTT in animals are given. We also question the authors' evaluation of semantic foresight and their even-handedness in assessing human and nonhuman behaviour.
