Palatability shift of a salt-associated incentive during sodium depletion

Previous studies of natural palatability-sensitive reactions, elicited from rats by tastes, have indicated that the taste of concentrated NaCl becomes more palatable during states of body sodium depletion. A training procedure based upon “sensory preconditioning” or “irrelevant incentive” designs was used here to establish gustatory conditioned labels (quinine or citric acid) for either NaCl or fructose while rats were in a normal physiological state. Experiment 1 replicated demonstrations by others that gustatory conditioned labels for salt can attract and act as independent incentives during the salt appetite induced by sodium depletion. Experiment 2 used the taste reactivity measure to show that the enhanced palatability of the taste of NaCl transfers to produce enhanced palatability of the taste of the isolated conditioned label for salt in a state-dependent fashion. These results offer further support for the proposition that conditioned incentives not only predict hedonic events to follow, but themselves become attributed with the hedonic properties of their reinforcers.     

Do Belief Reports Report Beliefs

Abstract: The traditional puzzles about belief reports puzzles rest on a certain seemingly innocuous assumption, that 'that'-clauses specify belief contents. The main theories of belief reports also rest on this "Specification Assumption", that for a belief report of the form 'A believes that p' to be true,' the proposition that p must be among the things A believes. I use Kripke's Paderewski case to call the Specification Assumption into question. Giving up that assumption offers prospects for an intuitively more plausible approach to the semantics of belief reports. But this approach must confront a puzzle of its own: it turns out that every case is a Paderewski case, at least potentially.     

LOSS OF SELF AS ETHICAL LIMIT

This Comment argues that Stephen Bush's critique of Georges Bataille's meditative practice fails to recognize how the disruption of the self, and the challenge to goal‐oriented activity that comprise the heart of that practice, serve as an ethical limit that protects against sadistic and violent engagement with the world. The ethical disposition fostered by Bataille's practice is a dissolution of the self.
