A mediational model of power, affiliation and achievement motives and product involvement

A model based on McClelland's theory of human motivation was proposed in which motive incentives mediated the relationship between motive level (n Power, n Affiliation and n Achievement) and product involvement. This hypothesis was tested with 142 college students. Results indicate that power motive incentives successfully mediated the relationship between power motive level and product involvement for the expensive car and interview clothing conditions. Affiliation motive incentives mediated the relationship between affiliation motive level and involvement for greeting cards but not gifts. The two achievement products (scientific calculator and computer manual) failed to meet most of the criteria for mediation.Laura Schmidt is a psychology doctoral student and Irene Frieze is a professor of psychology and business administration at the University of Pittsburgh.

Relationships among critical thinking skills, academic achievement, and misconceptions about psychology.

Two groups of 60 students each were selected from introductory college psychology classes. One consisted of high academic achievers, the other of average achievers. They were given the McCutcheon Test of Misconceptions, a 65-item, multiple-choice test designed to measure common misconceptions about psychology. Subsequently, they were also given the Watson-Glaser Critical Thinking Appraisal. Both groups made many errors on the McCutcheon test, but high academic achievers made significantly fewer errors on both the McCutcheon test and the Watson-Glaser than average achievers. A stepwise multiple regression consisting of Watson-Glaser subscales 1 (the ability to draw valid inferences) and 4 (ability to weigh and interpret evidence) and GPA successfully predicted McCutcheon test scores (R = .43). This suggests that even beginning students with high grades and good critical thinking skills are likely to harbor many misconceptions about psychology.     

Indulging anxiety: human enhancement from a Protestant perspective.

At the heart of any ethics of human enhancement must be some normative assumptions about human nature. The purpose of this essay is to draw on themes from a Protestant theological anthropology to provide a basis for understanding and evaluating the tension between maintaining our humanity and enhancing it. Drawing primarily on the work of theologian Reinhold Niebuhr, I interpret enhancement as proceeding from the anxiety that characterizes human experience at the juncture of freedom and finiteness. Religious and moral dimensions of human sinfulness are considered in relation to cultural values that motivate human enhancement generally. I employ these dimensions in a series of benchmarks to suggest a background of theological, anthropological, and moral considerations against which enhancement is not to be condemmed but rather critically evaluated.     

Picture-word differences and conceptual frequency judgments

Recent evidence suggests that while pictures are more easily recognized, discriminated, associated, and recalled than their corresponding verbal labels, this is not the case in concept acquisition/utilization tasks. If such evidence is interpreted in terms of a "frequency theory" perspective, one would expect the typically obtained frequency judgment differences between pictures and words to be reduced if "conceptual" frequency judgments are required. This expectation was confirmed in three experiments.
