Logics of Synonymy

Journal of Philosophical Logic - We investigate synonymy in the strong sense of content identity (and not just meaning similarity). This notion is central in the philosophy of language and in...     

Gettier Cases without False Lemmas?

Examples cited by Feldman, Lehrer and others of true beliefs that are justified, but not by false lemmas, turn out under scrutiny to involve false lemmas after all. In each case there is an EG inference whose conclusion is unwarranted unless its base instance is false. A shift to non-deductive justification does not avert the difficulty. The relation of this result to non-inferential Gettier cases is suggested.     

Dreams of traditional and nontraditional women: Are dream aggression and hostility related to higher levels of waking well-being?

In order to determine whether varying degrees of traditionality would be manifested in specific behaviors that would be present in women's waking and dreaming life, 100 women between the ages of 22 and 79, 12% of whom were African American, were administered a number of self-report measures of psychological well-being and were asked to complete ongoing dream diaries for a 2-week period. These instruments were then scored along with a variety of measures used to determine to what extent traditionality differentiated among the women. Randomly selected dreams from the dream diaries were scored for aggression, anxiety, emotion, hostility, self-efficacious problem-solving, and success/failure. While traditionality was not a significant factor among the self report scales, a number of significant relationships between traditionality and dream content scales were found. As predicted, nontraditionality was positively correlated with a high ratio of achievement-oriented success to failure interactions, self-efficacious problem-solving, and aggressive dream interactions. However, nontraditionality was also significantly correlated with higher overall dream hostility. The results are discussed within the context of recent dream function theory as well as within a broader sociocultural context on shifting gender roles.This research was completed in partial fulfillment of the first author's requirements for the doctoral degree in clinical psychology at Yeshiva University.

Sex differences in the object representations in the dreams of adolescents

The present study explored sex and age differences in the level of object representations and human movement in the dreams of adolescents. In order to test empirically the contention that early object relations are significantly linked to the formation of children’s gender identity, 389 dreams recorded by 115 adolescents, ages 15–18, were scored for object representations and levels of human movement. As predicted, there were significant differences in the quality of object representations in male and female adolescent’s dream content. In addition, female’s dreams contained significantly higher amounts of human movement than males’ dreams although these differences may well be attributable to longer dream narratives in the female sample. Further, these sex differences were most pronounced at the highest end of the sample age range. Results are discussed in terms of object relations adolescent development. The authors wish to thank Patricia Heenan, M.A., for her invaluable assistance with data management, Alice Pope, Ph.D., for her helpful suggestions, and Dave Cowen, Ph.D., for making his data available to us.

Thinking about decisions: An integrative approach of person and task factors

Decisions vary. They may vary in both content and complexity. People also vary. An important way that people vary is how much they think. Some prior research investigating thinking and decision making largely conflicts with most traditional decision theories. For example, if considering an array of products to choose from, thinking more about the alternative's attributes should lead to a better decision. However, some research indicates that thinking more may also lead to focusing on irrelevant aspects of the decision and a less optimal outcome. We propose that this conflict in the literature exists because of a failure to consider the interaction between the individual and the decision task. To test this, we used separate methodologies that enhance or attenuate a person's thinking. In Study 1, we selected people who were especially high or low in need for cognition and had them complete a robust decision-making inventory, which included both complex and simple tasks. In Study 2, we manipulated participant's level of glucose, which acts as the brain's fuel to enhance or attenuate thinking ability. Both studies provide insight for understanding our central tenant that more thought leads to better decisions in complex tasks but does not influence simple decisions. These findings show how the individual's thinking can interact with the constructive elements of the task to shape decision choice.
