Context Matters: Emotional Sensitivity to Probabilities and the Bias for Action in Cancer Treatment Decisions.

Background: Past studies have shown a commission bias for cancer treatment, a tendency to choose active treatment even when watchful waiting is less risky. This bias suggests motivations for action beyond mortality statistics, but recent evidence suggests that individuals differ in their emotional sensitivity to probabilities (ESP), the tendency to calibrate emotional reactions to probability. The current study aims to examine the role of ESP in the commission bias, specifically whether those higher in ESP are more likely to choose watchful waiting when risk probabilities align with that choice.

The role of emotional sensitivity to probability in the decision to choose genetic testing.

While the availability of genetic testing is rapidly increasing, many opt out of testing. The decision to test or not is emotionally charged, and both clinical research and theoretical work in psychology show that in emotional decisions, people often struggle to interpret and utilize risk information. Clinical research on genetic testing uptake also shows that feeling overwhelmed by numeric information may be a deterrent to testing.

Compared to what? A joint evaluation method for assessing quality of life.

Purpose: This study tests whether a joint evaluation method for assessing quality of life can stabilize ratings by providing contextual information, thereby helping participants calibrate responses on a rating scale. We also use the method to test for scale recalibration between patients and non-patients.

Method: In an Internet survey, participants (N = 1,865) rated a target health condition, either diabetes or obesity, on a 100-point rating scale.

The development of abstract letter representations for reading: evidence for the role of context.

We review evidence that in the course of reading, the visual system computes abstract letter identities (ALIs): a representation of letters that encodes their identity but that abstracts away from their visual appearance. How could the visual system learn such a seemingly nonvisual representation? We propose that different forms of the same letter tend to appear in similar distributions of contexts (in the same words written in different ways) and that this environmental correlation interacts with correlation-based learning mechanisms in the brain to lead to the formation of ALIs. We review a neural network model that demonstrates the feasibility of this common contexts hypothesis and present two experiments confirming some novel predictions: (a) repeatedly presenting arbitrary visual stimuli in common contexts leads those stimuli to be confusable with each other, and (b) different forms of the same letter are more confusable with each other in word-like contexts than in nonword-like contexts.

Are they really that happy? Exploring scale recalibration in estimates of well-being.

Objective: The authors addressed a lingering concern in research on hedonic adaptation to adverse circumstances. This research typically relies on self-report measures of well-being, which are subjective and depend on the standards that people use in making judgments. The authors employed a novel method to test for, and rule out, such scale recalibration in self-reports of well-being.
