Humean dispositionalism

Humean metaphysics is characterized by a rejection of necessary connections between distinct existences. Dispositionalists claim that there are basic causal powers. The existence of such properties is widely held to be incompatible with the Humean rejection of necessary connections. In this paper I present a novel theory of causal powers that vindicates the dispositionalist claim that causal powers are basic, without embracing brute necessary connections. The key assumptions of the theory are that there are natural types of causal processes, and that manifestations of powers are identified with certain kinds of causal processes. From these assumptions, the modal features of powers are explained in terms of internal relations between powers themselves and the process-types in which powers are manifested.     

The development of and interaction among alerting,orienting, and executive attention in children

A sex-balanced sample (N = 96) of children from age 6.5 to age 12.5 completed a modified Attention Network Test. Across these ages, we found evidence for developmental changes to alerting and executive control but stable orienting. Additionally, we found that the youngest members of our sample manifested an interaction between alerting and executive control that is opposite to that typically found in adults; a reversal that diminishes with age to achieve the adult pattern by the older end of the age range of our sample.     

Defense,dreams and rationality

Are some mental activities rational but unconscious? Psychopathological symptoms, it is said, have a sense — they are seen as “compromise-formations” which express the “intentions” of agents even though the agents are totally unaware of “bringing about” such symptoms. Philosophers, who often claim that such a conception is simply contradictory or incoherent, have shed little light on the puzzles and apparent paradoxes that surround the issue. It is argued here that Freud's two models of explanation — the mechanistic and the intentionalistic — each fail to provide a basis for an explanatory account of the phenomenon of unconscious defense. An examination of the problem of dream “composition” helps explain why Freud's dependence upon “rational homunculi” is inappropriate and misleading. Finally, an alternative model which depends neither upon Freud's version of mechanism nor upon his lavish anthropormorphism is suggested. Ladies and Gentlemen, — It was discovered one day that the pathological symptoms of certain neurotic patients have a sense. On this discovery the psychoanalytic method of treatment was founded. It happened in the course of the treament that patients, instead of bringing forward their symptoms, brought forward dreams. A suspicion thus arose that the dreams too had a sense.     

Relevant Restricted Quantification

The paper reviews a number of approaches for handling restricted quantification in relevant logic, and proposes a novel one. This proceeds by introducing a novel kind of enthymematic conditional.
