ACTIONS,HABITS AND CONSTITUTION

In this paper I offer a critique of the view made popular by Davidson that rationalization is a species of causal explanation, and propose instead that in many cases the explanatory relation is constitutive. Given Davidson’s conception of rationalization, which allows that a huge range of states gathered under the heading ‘pro attitude’ could rationalize an action, I argue that whilst the causal thesis may have some merit for some such ‘attitudes’, it has none for others. The problematic ‘attitudes’ are those which can be attributed to the agent only on the basis of her history of doing a certain sort of thing. In other words, they are among the agent’s habits. I argue that such temporally extended states cannot be the causes of any present occurrence. Instead, I suggest we should think of the present action as partly constituting the state in question, and give a corresponding interpretation of the explanatory relation. Such explanations invite us to abandon a conception of agency narrowly based on psychology, in favour of an enriched one which takes an agent’s habits to partly constitute the agent.     

INFANTS' INDIVIDUATION AND ENUMERATION OF ACTIONS

Abstract— Two experiments examined 6-month-old infantsapos; ability to individuate and enumerate physical actions—the sequential jumps of a puppet In both experiments, which employed a habituation paradigm, infants successfully discriminated two-jump from three-jump sequences The sequences of activity in the two experiments provided for an initial exploration of the cues infants use to individuate actions. Results show that (a) infants can individuate and enumerate actions in a sequence, indicating that their enumeration mechanism is quite general in the kinds of entities over which it will operate, (b) action whose temporal boundaries are characterized by a contrast between motion and absence of motion are especially easy to individuate and enumerate, but nonetheless (c) infants can individuate and enumerate actions embedded in a sequence of continuous motion, indicating that infants possess procedures for parsing an ongoing motionful scene into distinct portions of activity.     

ACTIONS AND AGENTS: NATURAL AND SUPERNATURAL RECONSIDERED

Using a process‐oriented understanding of the relation between actions and agents, the author argues that an ontological agent is the ongoing effect or by‐product rather than the antecedent cause of actions. Applied to the relation between natural and supernatural in philosophical cosmology, this allows one to claim, first, that agents (whether natural or supernatural) are not sensibly perceived, but only inferred from the ongoing observation of empirical actions; second, that the distinction between the natural and the supernatural is then conceivably a distinction between interrelated processes rather than between independently existing agents; and third, that a higher order process of supernatural origin could be operative in a lower order empirical process without interference even though its existence and activity could only be established on the basis of a faith commitment, not empirical evidence. What Paul Ricoeur referred to as a “surplus of meaning” over and above the scientific explanation of an event would be in play with the claim of divine guidance for the cosmic process.     

ASSESSING AND INCREASING PHYSICAL ACTIVITY

Increasing physical activity is a crucial component of any comprehensive approach to combat the growing obesity epidemic. This review summarizes recent behavioral research on the measurement of physical activity and interventions aimed at increasing physical activity and provides directions for future research.     

MODIFICATION OF ACTIVITY LEVEL THROUGH BIOFEEDBACK AND OPERANT CONDITIONING1

The biomotometer, an electronic device that simultaneously measures activity and provides auditory feedback to the subject, was used in combination with material reinforcers in two experiments attempting to modify activity level in children. In the first study the activity level of an 11-year-old highly active boy was decreased below mean baseline during conditioning in a classroom setting. His level of activity returned to baseline when feedback was withdrawn. In the second study, activity level of a 10-year-old hypoactive boy was increased over mean baseline level during conditioning in a free-play setting, and returned to slightly below baseline during five extinction trials. Results of these studies indicate that the biomotometer is a useful instrument for modification of activity level.
