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)
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)
Although hand preference is one of the best known features of performance, a recent study of object transfer behavior (Coelho, Studenka, & Rosenbaum, J Exp Psychol Human Percept Perform, 40:718-730, 2014) showed that people place greater emphasis on using the hand that avoids extreme joint angles than on using the hand they normally prefer. In the present(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)
Dear Sir: In an earlier letter on another matter, Chapman and Johnson (1978) identified a paradox facing a widely held stoichiometric model for ATP utilization in active ion transport. Their well-reasoned and carefully documented argument summarized two apparently conflicting points of evidence. First, the net rate of ATP hydrolysis not only varies with(More)
