We congratulate Michelle Quee on the award of her PhD! Her thesis entitled “Multiple Categorization: Choices and Constraints in the Perception of Individuals and Groups” makes use of the ‘who-said-what’ paradigm to explore the role of comparative fit, normative fit, and perceiver readiness factors in multiple categorization at a range of levels of perceptual hierarchy. Michelle’s thesis breaks new ground in the application of this complex paradigm, and in significantly extending the use of the salience model in self-categorization theory. Congratulations Dr. Quee.
