On Understanding Leśniewski

Tarski's manner of defining truth is generally considered highly significant. About why, there is less consensus. I argue first, that in his truth-definitions Tarski was trying to solve a set of philosophical problems; second, that he solved them successfully; third, that all of these that are simply problems about defining truth are as well or better solved by a simpler account of truth. But one of his crucial problems remains: to give an account of validity, one requires an account not just of truth but of truth under varying interpretations. Tarski's account has the merit of generalizing to this, to model theory and to abstract algebra.     

How do i know what i feel? Evidence for the role of self‐categorisation in symptom perceptions

This paper extends the self‐categorisation model of symptom appraisals to predict that individuals who believe they have a given illness will perceive concurrent symptoms relevant to that illness to be more severe when they categorise themselves as members of a group of people with that illness. These predictions are supported with opportunity samples of individuals reporting, or not reporting a common cold (Study 1, N = 60) and reporting colds or tinnitus (Study 2, N = 64). In both studies, relevant symptoms were rated as more severe when illness group memberships were salient. The methodological, theoretical and clinical implications of these findings and possible therapeutic applications of self‐categorisation theory (SCT) to symptom perceptions are discussed.
