Although psychology is the science of mental life and behavior, little attention has been paid to the means by which mental life is translated into behavior. One domain in which links between cognition and action have been explored is the manipulation of objects. This article reviews psychological research on this topic, with special emphasis on the(More)

Humans (Homo sapiens) anticipate the consequences of their forthcoming actions. For example, they grasp objects with uncomfortable grasps to afford comfortable end positions-the end-state comfort (ESC) effect. When did such sophisticated motor planning abilities emerge in evolution? We addressed this question by asking whether humans' most distant living(More)
Actions that are chosen have properties that distinguish them from actions that are not. Of the nearly infinite possible actions that can achieve any given task, many of the unchosen actions are irrelevant, incorrect, or inappropriate. Others are relevant, correct, or appropriate but are disfavored for other reasons. Our research focuses on the question of(More)
1. Afferent discharges from single atrial mechanoreceptors were studied in vitro in isolated, perfused cat hearts, by balloon inflation and by localized endocardial stretching with step and ramp wave forms. 2. Receptor excitability could be maintained for several hours with perfusion, but failed reversibly within a half hour without it. 3. Responses to pure(More)
Vaesen asks whether goal maintenance and planning ahead are critical for innovative tool use. We suggest that these aptitudes may have an evolutionary foundation in motor planning abilities that span all primate species. Anticipatory effects evidenced in the reaching behaviors of lemurs, tamarins, and rhesus monkeys similarly bear on the evolutionary(More)
Transfer functions of the input impedance Z(f) and coupling ratio H(f) were measured from the paired Retzius cells of leech segmental ganglia, using sinusoidal and pseudorandom test test currents. The data were compared with two classes of linear electric circuit models of electrotonic coupling, one with a purely resistive junction, and the other with a(More)

art gallery 44 ARTIST STATEMENT My sculptures represent motion in static form. Using digital tools, the shapes are derived from various animations of a figure, with the arc of a body's motion defining each form. Though the work may be compared to early Modernist paintings by Duchamp and Balla, they depict time as a continuum, rather than as a collection of(More)
Previous research has demonstrated that nontool-using primates are capable of sophisticated motor planning for a single action. The present study extends this work by asking whether monkeys are capable of planning a sequence of repetitive motor actions to accommodate a task demand. We presented tamarins with a tape measure baited with a food reward at near(More)
