1. Wilson, Daniel Joseph. The Dynamics of Decision Making: Attribute Evaluation and Weighting.

Degree: 2017, University of Toronto

The aim of the present research was to investigate the evaluation and weighting mechanisms people employ in multi-attribute decision making. In a Primary and Supplementary Study, I developed a choice task that required subjects to assess the summed value of two attributes and, based on this value, make an accept or reject decision. The Primary Study employed a novel experimental paradigm which allowed us to dynamically track subject attention, with stimulus values that could be dynamically reweighted via the addition of â multipliersâ , which magnified attribute values on a trial-by-trial basis. I found that people were able to accurately re-weight attribute when making decisions. Results also revealed that people tend to fixate longer on stimuli that have been re-weighted. Finally, I developed a computational model of the task using drift diffusion modeling, which provides the basis for future imaging studies to extend this work in a search for neural correlates of attribute evaluation and weighting.

2. Lin, Hause. Neurophysiological Signals Parametrically Track Subjective Conflict during Intertemporal Choice.

Degree: 2016, University of Toronto

When choosing between equally desirable options, how is decision conflict represented in the brain? We measured neurophysiological signals that are believed to reflect decision processes in different brain regions as participants made intertemporal decisions. Participant-specific delayed rewards (e.g., $20.30 in 10 days)â generated based on each participant's hyperbolic discount functionâ were presented to parametrically vary the amount of decision conflict in different choice pairs. We found that conflict negativity and pupil dilation track varying degrees of conflict, suggesting the anterior cingulate and locus coeruleus/norepinephrine system are implicated in value comparison and conflict monitoring processes. We show that the neuroeconomic and psychophysiological approaches can be integrated to better understand the neural systems and processes underlying decision making.
