An Exploration of Johnson's Sense of ‘Argument’

This essay attempts to give definitions and identity conditions for the two predominant senses of Argument currently in use, the one involving reasons for a conclusion and the other denoting an expressed disagreement with ensuing verbal behaviour by two parties. I see Johnson's new concept of Argument, as developed in his book Manifest Rationality, as a hybrid of the two common senses of Argument, and, accordingly, I try to define and give the identity conditions of Johnson-arguments. Finally, I disagree with Johnson on the nature of the definition he thinks he has proposed, and I conclude with observations suggesting that his logical perspective has dialectical and rhetorical components.     

On the sampling theory roundations of item response theory models

Item response theory (IT) models are now in common use for the analysis of dichotomous item responses. This paper examines the sampling theory foundations for statistical inference in these models. The discussion includes: some history on the stochastic subject versus the random sampling interpretations of the probability in IRT models; the relationship between three versions of maximum likelihood estimation for IRT models; estimating versus estimating -predictors; IRT models and loglinear models; the identifiability of IRT models; and the role of robustness and Bayesian statistics from the sampling theory perspective.A presidential address can serve many different functions. This one is a report of investigations I started at least ten years ago to understand what IRT was all about. It is a decidedly one-sided view, but I hope it stimulates controversy and further research. I have profited from discussions of this material with many people including: Brian Junker, Charles Lewis, Nicholas Longford, Robert Mislevy, Ivo Molenaar, Donald Rock, Donald Rubin, Lynne Steinberg, Martha Stocking, William Stout, Dorothy Thayer, David Thissen, Wim van der Linden, Howard Wainer, and Marilyn Wingersky. Of course, none of them is responsible for any errors or misstatements in this paper.

The influence of CS-US interval on several different indices of learning in appetitive conditioning

Four experiments examined the effects of varying the conditioned stimulus-unconditioned stimulus (CS-US) interval (and US density) on learning in an appetitive magazine approach task with rats. Learning was assessed with conditioned response (CR) measures, as well as measures of sensory-specific stimulus-outcome associations (Pavlovian-instrumental transfer, potentiated feeding, and US devaluation). The results from these studies indicate that there exists an inverse relation between CS-US interval and magazine approach CRs, but that sensory-specific stimulus-outcome associations are established over a wide range of relatively long, but not short, CS-US intervals. These data suggest that simple CR measures provide different information about what is learned than measures of the specific stimulus-outcome association, and that time is a more critical variable for the former than latter component of learning.     

Parental Attachment and Adjustment to College: The Mediating Role of Avoidant Coping

Many studies have documented an association between parental attachment and college student adjustment. Few studies have explored the mechanisms underlying this association. The authors asked college students nearing the end of their first academic year to complete instruments measuring parental attachment, coping, and adjustment to college. Structural equation modeling was used to model mediation separately for attachment to mother and father. Avoidant coping mechanisms (operationalized as denial, mental disengagement, behavioral disengagement, and substance use) significantly mediated the parental attachment and adjustment to college relationship. Self-sufficient coping mechanisms (operationalized as planning, positive reinterpretation, acceptance, active coping, and suppression) did not mediate the parental attachment and adjustment to college relationship.

Teaching cultural sensitivity in psychological assessment: a modular approach used in a distance education program

In this article, I describe the teaching and evaluation of 8 multicultural assessment competencies in an American Psychological Association accredited, distance education, clinical psychology doctoral program. This modular approach consists of 15 hr of face-to-face, didactic and experiential multicultural assessment training designed to (a) augment personal awareness, (b) develop a conceptual base, (c) provide exposure to available assessment technologies, (d) ensure an understanding of an integrative model of culturally sensitive assessment, and (e) offer opportunities to apply this material to assessment cases. In addition to completing this training, students are evaluated on these competencies as part of their preinternship clinical comprehensive. I present preliminary evaluative outcome data as well as a critique of this approach.     

Human responses in assessing object relations subscales of the Psychoanalytic Rorschach Profile

The Rorschach test is often used to assess object relations. This research examined whether human responses are necessary for a valid assessment.     

Learning to optimize speed, accuracy, and energy expenditure: a framework for understanding speed-accuracy relations in goal-directed aiming

Over the last century, investigators have developed a number of models to explain the relation between speed and accuracy in target-directed manual aiming. The models vary in the extent to which they stress the importance of feedforward processes and the online use of sensory information (see D. Elliott, W. F. Helsen, & R. Chua, 2001, for a recent review). A common feature of those models is that the role of practice in optimizing speed, accuracy, and energy expenditure in goal-directed aiming is either ignored or minimized. The authors present a theoretical framework for understanding speed-accuracy tradeoffs that takes into account the strategic, trial-to-trial behavior of the performer. The strategic behavior enables individuals to maximize movement speed while minimizing error and energy expenditure.
