ACADEMIC HARASSMENT

Although much has been written concerning the sexual harassment of university students, no research has yet directly examined the behaviors of university professors themselves. The present study describes the responses of 235 male faculty members of a prestigious, research-oriented university who responded to a survey inquiring about social and sexual interaction among faculty and students. Although the majority of the responses focused on mentoring and social interactions, a sizable minority (26%) reported sexual involvement with women students. In addition to item frequencies, a structural analysis of the phenomenon of academic harassment is presented, and discussed in the context of the subjects' responses to an open-ended invitation to comment on the study.     

Young infants are pro-victims,but it depends on the context

The current study examined whether and when young infants are sensitive to distressed others, using two experiments with a forced-choice paradigm. Experiment 1 showed that 5- to 9-month-old infants demonstrate a clear pro-victim preference: Infants preferred a distressed character that had been physically harmed over a matched neutral character. Experiment 2 showed that infants’ preference for a distressed other is not invariable, but rather depends on the context: Infants no longer preferred the distressed character when it expressed the exact same distress but for no apparent reason. These findings have implications for the early ontogeny of human compassion and morality, addressed in the discussion.     

Dealing with Possible Baseline Inequalities Between Experimental Groups – The Case of Motor Learning

Abstract

One important concept of experimental design is the random assignment of participants to experimental groups. This randomization process is used to prevent selection bias, as well as to provide a strong basis for a cause-and-effect relationship between the independent variable/s and the dependent variable/s. In small sample sizes, simple randomization may not provide equal groups at baseline for one or more of the variables, and therefore more restricted types of randomization, such as the stratified permuted-block randomization, can be used. A code was written to calculate the probability that simple randomization will not lead to equality between groups at baseline, and then an example of stratified permuted-block randomization was examined. The findings suggest that for certain variables that are commonly measured in experiments in motor learning, there is a relatively high probability that groups will not be equal at baseline after simple randomization. This observation reflects the small sample sizes usually found in the literature on motor learning. However, stratified permuted-block randomization does lead to greater equality among groups. Implications for researchers are discussed, and a flowchart is proposed that will allow researchers to decide whether to use simple or stratified randomization.
