Presence and Reality Judgment in Virtual Environments: A Unitary Construct? This theory proposes a central executive that, among other things, is responsible for directing attention to relevant information, suppressing irrelevant information and inappropriate actions, and for coordinating cognitive processes when more than one task must be done at the same time. Specifically, current definitions tend to suggest that intelligence is the ability to: Learn from experience: The acquisition, retention, and use of knowledge is an important component of intelligence. And so, this brief foray into the long journey of primate evolution has brought us back to selective attention and to the posterior parietal cortex, but with a different perspective on both. NCI CPTC Antibody Characterization Program. While vital to the human experience, it remains obscure and hidden - the ghost in the machine (Hofstadter & Dennett, 1982). Butler, A. In view of a failure of this approach, as is obvious for the case of attention versus intention, two reactions are to be expected. In this article, we challenge the usefulness of attention as a unitary construct and/or neural system. We thus conclude that selectivity emerged through evolution as a design feature to enable efficient goal-directed action. . Tipper, S.P., Meegan, D., & Howard, L.A. (2002). 739752) Cambridge, MA: MIT Press. In contrast, we could not confirm a unitary construct underlying the DSM-IV or DSM-5 definitions of PTSD. 1). Spatial neglect and attention networks. The episodic buffer resembles Tulving's concept of episodic memory, but it differs in that the episodic buffer is a temporary store.[6]. The snooze of lose: Rapid reaching reveals that losses are processed more slowly than gains. Experimental Brain Research, 105, 261-275. This emphasis on integrated sensori-cognitive-motor processes takes inspiration from the synthetic approach to understanding cognition (Hommel & Colzato, 2015) and a proposed phylogenetic refinement of the scientific approach to understanding behavior (Cisek, 2019 [this issue]).
