Variables affecting specialty choice in occupational therapy.
Over the past 15 years, the number of occupational therapists entering the practice area of mental health has greatly declined. To determine the possible reasons for this decline, a random sample of 450 occupational therapy students who graduated in 1986 was surveyed to identify those factors that influence practice choice. Participants were asked to indicate their practice preferences at five ...
متن کاملNoisy Parameters in Risky Choice
We examine the effect of variability in model parameters on the predictions of expected utility theory and cumulative prospect theory, two of the most influential choice models in decision making research. We find that zero-mean and symmetrically distributed noise in the underlying parameters of these models can systematically distort choice probabilities, leading to false conclusions. Likewise...
متن کاملEye Movements in Risky Choice
We asked participants to make simple risky choices while we recorded their eye movements. We built a complete statistical model of the eye movements and found very little systematic variation in eye movements over the time course of a choice or across the different choices. The only exceptions were finding more (of the same) eye movements when choice options were similar, and an emerging gaze b...
متن کاملRisky Weighting in Discrete Choice
This paper presents a new approach to discrete choice analysis for risky prospects. Conventional discrete choice analysis focuses on riskless prospects and does not deal with the scenario where the alternatives that the decision-makers choose from are associated with risk. In this paper, we investigate decisionmakers’ risk perception and choice behaviour in choice experiments when they are faci...
متن کاملMenu Dependence in Risky Choice
Economic theory assumes that individuals have stable preferences for risky choice options. This research challenges this assumption and demonstrates that preferences for risky options are constructed contingent on which other options constitute the decision maker’s choice set. This leads to systematic violations of normative choice axioms thereby leading to inefficient choice. Expertise in eval...
