Individual Differences In Categorization, Urooj Anees

Undergraduate Student Research Internships Conference

The appearance of individual differences used to be regarded as noise in psychological experiments, but is slowly becoming a tool used to enhance and solidify findings in various fields of cognitive psychology. This presentation aims to very briefly discuss individual differences and categorization and what questions future research could aim to answer.

Neural Representation Of Stimulus Category Membership Across Modalities, Carson Rumble-Tricker

Undergraduate Student Research Internships Conference

Category learning is a process through which common features among category members, distinctive features among non-members, or even both, are identified (Hammer et al., 2009). This process is a critical aspect of cognition and can guide decision making and information inference. Furthermore, category learning is involved among a large number of stimuli, including visual (Folstein et al., 2013), auditory (Ley et al., 2012), olfactory (Qu et al., 2016), and multisensory (Viganòa, Borghesani, & Piazza, 2021) stimuli.

The aim of this systematic review is to determine and qualitatively analyze studies that investigate the changes in the neural representations of stimuli that …

Testing The Bayesian Confidence Hypothesis, Wei Ji Ma, Ronald Van Den Berg

MODVIS Workshop

Asking subjects to rate their confidence is one of the oldest procedures in psychophysics. Remarkably, quantitative models of confidence ratings have been scarce. The Bayesian confidence hypothesis (BCH) states that an observer’s confidence rating is monotonically related to the posterior probability of their choice. I will report tests of this hypothesis in two visual categorization tasks: one requiring rapid categorization of a single oriented stimulus, the other a deliberative judgment typically made by scientists, namely interpreting scatterplots. We find evidence against the Bayesian confidence hypothesis in both tasks.
