This paper describes a comparative study of three usability test approaches: concurrent thinkaloud protocols, retrospective think-aloud protocols, and constructive interaction. These three methods were compared by means of an evaluation of an online library catalogue, which involved four points of comparison: number and type of usability problems detected; relevance of the problems detected; ov...

Think-aloud protocols are a dominant method in usability testing. There is, however, only little empirical evidence on the actual validity of the method. This paper describes an experiment that compares concurrent and retrospective think-aloud protocols for a usability test of an online library catalogue. There were three points of comparison: usability problems detected, overall task performan...

Two studies demonstrate that a dispositional proneness to disgust ("disgust sensitivity") is associated with intuitive disapproval of gay people. Study 1 was based on previous research showing that people are more likely to describe a behavior as intentional when they see it as morally wrong (see Knobe, 2006, for a review).

We present an algorithm for automatically constructing a decompositional shape model from examples. Unlike current approaches to structural model acquisition, in which one-to-one correspondences among appearance-based features are used to construct an exemplar-based model, we search for many-tomany correspondences among qualitative shape features (multi-scale ridges and blobs) to construct a ge...

I THINK IT SAFE TO SAY that just about everyone connected to resident recruitment has been amazed by the number ofmedical students whohave had experience with or have expressed interest in work in low-income countries. Indeed, a growing number of our surgical residents envision themselves becoming involved in the nascent branch of global health, now increasingly referred to as global surgery. G...
