Newcomb's Problem,Prisoners' Dilemma,and collective action

Among various cases that equally admit of evidentialist reasoning, the supposedly evidentialist solution has varying degrees of intuitive attractiveness. I suggest that cooperative reasoning may account for the appeal of apparently evidentialist behavior in the cases in which it is intuitively attractive, while the inapplicability of cooperative reasoning may account for the unattractiveness of evidentialist behaviour in other cases. A collective causal power with respect to agreed outcomes, not evidentialist reasoning, makes cooperation attractive in the Prisoners' Dilemma. And a natural though unwarranted assumption of such a power may account for the intuitive appeal of the one-box response in Newcomb's Problem.This paper was originally submitted to Synthese in March 1989.

Assessing text representations with recognition: The interaction of domain knowledge and text coherence

Readers construct at least 2 interrelated mental representations when they comprehend a text: a textbase and a situation model. Two experiments were conducted with recognition memory to examine how domain knowledge and text coherence influence readers' textbase and situation-model representations. In Experiment 1, participants made remember-know judgments to text ideas. Knowledge and coherence interacted to influence remember judgments differently than know judgments. In Experiment 2, the authors used the process-dissociation procedure to obtain recollection and familiarity estimates. Knowledge and coherence interacted to influence recollection estimates but not familiarity estimates. The authors claim that recollection and familiarity can be used as markers of the different processes involved in constructing a textbase and a situation model.     

Culture-based perceptions of academic achievement among low-income elementary students

This study examined the influence of culture on students' perceptions of academic success. Students read scenarios depicting hypothetical classmates achieving success through the cultural themes of individualism, competition, communalism, or verve. Students reported their social endorsement for the hypothetical classmates. A 2x4 repeated measures analysis, examining the effects of cultural group and cultural theme on students' endorsement, revealed an interaction between the two variables. African American students were significantly more accepting of communal and vervistic high-achieving peers than European American students. European American students endorsed individualistic and competitive high achievers significantly more than African American students. These and other findings suggest that the value students attach to academic success should not be understood in the absence of cultural considerations.     

Background factors predicting accuracy and improvement in micro expression recognition

Micro expressions are brief facial expressions displayed when people attempt to conceal, hide, or repress their emotions. They are difficult to detect in real time, yet individuals who can accurately identify micro expressions receive higher workplace evaluations and can better detect deception. Two studies featuring college students and security officers examined background factors that may account for accuracy differences when reading micro expressions, both before and after training. Study 1 revealed that college students who were younger and high in openness to experience were better at recognizing micro expressions. However, individual differences did not predict improvement in micro expression recognition gained through training. Study 2 revealed experiential factors such as prior facial expression training and lack of law enforcement experience were more predictive of micro expression recognition than personality or demographic factors. Individuals in both studies showed recognition improvement with training, and the implications of the ability to improve at micro expression recognition are discussed in the context of security and interpersonal situations.
