Epistemic Justice and a Role for Virtue in the Politics of Knowing

The dual aim of this article is to reveal and explain a certain phenomenon of epistemic injustice as manifested in testimonial practice, and to arrive at a characterisation of the anti–prejudicial intellectual virtue that is such as to counteract it. This sort of injustice occurs when prejudice on the part of the hearer leads to the speaker receiving less credibility than he or she deserves. It is suggested that where this phenomenon is systematic it constitutes an important form of oppression.     

The Confidence of Eyewitnesses in Their Identifications From Lineups

The confidence that eyewitnesses express in their lineup identifications of criminal suspects has a large impact on criminal proceedings. Many convictions of innocent people can be attributed in large part to confident but mistaken eyewitnesses. Although reasonable correlations between confidence and accuracy can be obtained under certain conditions, confidence is governed by some factors that are unrelated to accuracy. An understanding of these confidence factors helps establish the conditions under which confidence and accuracy are related and leads to important practical recommendations for criminal justice proceedings.     

EVALUATION OF THE MULTIPLE-STIMULUS WITHOUT REPLACEMENT PREFERENCE ASSESSMENT METHOD USING ACTIVITIES AS STIMULI

The current study examined the accuracy of the multiple-stimulus without replacement (MSWO) preference assessment for identifying preferred common classroom activities as reinforcers with children with behavioral disorders. The accuracy of predictions from the MSWO regarding high, medium, and low stimulus preference was tested by providing contingent access to activities for completing math problems within an independent seatwork format. Overall, there was an interaction effect between preference ranking (high, medium, or low) and number of problems completed. The results confirm and extend previous findings regarding the accuracy of predictions with the MSWO. The findings also reveal, however, some individual differences that may account for instances in which student behavior did not conform to predictions of stimulus preference assessments.     

An automated system for mapping spatial movement patterns in behavioral research

A computerized positioning system was developed and used to map gross body movement of children around a room in response to high-intensity sound stimulation. Details of the data collection system are discussed. The system has potential for use in a variety of research projects when it is necessary to identify position coordinates and analyze changes in spatial location for subjects within a test room environment.
