Abstract
A bewildering array of sciences, theories, and methodologies offer researchers many difficult choices when studying emotion or designing affective technologies. Thus, clarity of focus is a prime virtue of good work, as illustrated in the Aylett and Paiva (2012) article. The social sciences remain fundamentally undecided about how to conceptualize human variations, including how to measure culture and personality, and even about whether these two commonly used words have real meaning. This disagreement is pronounced in human-centered computing, because cognitive and rational-choice perspectives are technically easiest to apply, and these make little room for culture and personality. The article employs a modular approach, which can inspire researchers following alternative conceptualizations to substitute their own preferred choices
