Dialectical Behavior Therapy: Does It Bring About Improvements in Affect Regulation in Individuals with Eating Disorders?

The current investigation sought to determine whether a standard outpatient dose of dialectical behavior therapy (DBT) skills training (2 h per week) coupled with standard CBT treatment would be sufficient to produce changes in affect regulation over the course of day hospitalization treatment. In an uncontrolled pre-post treatment design, 65 women diagnosed with anorexia nervosa or bulimia nervosa were assessed at the beginning of treatment and at the end of treatment on affect regulation. Findings indicated that participants demonstrated a significant improvement in their ability to regulate affect, suggesting that weekly DBT treatment may play an important role in producing changes in affect regulation. Secondary analyses on eating disorder outcomes revealed a significant increase in weight gain as well as a significant reduction in restriction, bingeing, purging and eating disordered cognitions. Findings are discussed in the context of clinical and treatment implications for those with severe eating disorders.     

A Reinforcer Pathology perspective on relapse

The Reinforcer Pathology theory proposes conditions under which drugs emerge as excessively preferred reinforcers compared to other available reinforcers among drug users. The theory highlights 2 key variables as important determinants of drug preference: (a) excessive preference for immediate rewards (high discounting of future rewards); and (b) excessive valuation for addictive reinforcers (e.g., drugs). Two iterations of the Reinforcer Pathology theory exist with the latest iteration (i.e., Reinforcer Pathology 2.0) specifying that the temporal window of reinforcer integration (measured by delay discounting) is a determinant of reinforcer value. The 2 iterations of the Reinforcer Pathology theory are described. A novel insight and understanding of abstinence and relapse from a Reinforcer Pathology perspective, limitations, and future directions are discussed. The Reinforcer Pathology theory continues the long-standing efforts to scientifically understand and better define novel concepts and methods to further translational research and improve treatment outcomes. Exploring the complementary relation between the Reinforcer Pathology perspective and other current approaches could have a valuable effect.     

Reading and Character: Weil and McDowell on Naïve Realism and Second Nature

Both Simone Weil and John McDowell analogize value or meaning to sensations such as colour or heat, and this analogy is a strategy for resisting anti‐realism. However, McDowell's analogy tacitly accepts the very dualism which he is criticizing, while Weil's analogy is both more naïve and more radical than his. Like McDowell, Weil argues that virtuous character is the actualization of a second nature, but she emphasizes the role of the body in this process. Fully trained, the agent's body is a transparent medium through which she reads circumstances – and through which the circumstances, clearly perceived, express themselves in action.     

Parent and actometer measures of motor activity level in the young infant

Motor activity level is one dimension of infant temperament for which parental judgment can be validated against a truly independent criterion. Two studies were conducted, the first involving a 27-min sample of behavior in a structured, attention-getting situation, and the second involving a 24-hr sample of in-home behavior. In both studies, parent perception of the 3- or 4-month-old as measured by the Activity Level (AL) scale of the Rothbart Infant Behavior Questionnaire was compared to the composited readings from four mechanical motion recorders (actometers) worn, one per limb, by the infant. The AL scale did not correlate with the actometer measure, r=.05 and R=.00, and the expected convergence of the 3-month version of the IBQ activity scale with its mechanical counterpart was not found. In the 24-hr study, birth order and ponderal index were significantly correlated with 24-hr actometer scores; first-borns and thin infants were most active.     

Knowing when to move on: cognitive and perceptual decisions in time

We investigated people's ability to decide how much time to spend on the task at hand. To make such decisions well, one must take into account, among other things, the cost of failing and how one's task performance changes as a function of time. We first investigated timing decisions when the underlying task was perceptual. Decisions were highly efficient and suggested that people can make good use of perceptual knowledge and abstract reward information. Previous studies have found that perceptual decisions are generally optimal, but that cognitive decisions are generally suboptimal--a perception-cognition gap. Does a similar gap exist for timing decisions? We compared timing decisions for a perceptual task with timing decisions for more cognitive tasks. Performance was highly similar across the tasks, which suggests that knowledge can be acquired, and used to make timing decisions, in an equally efficient way regardless of whether that knowledge is derived through perceptual or cognitive experience.     

Domain specific effects of central traits in impression formation

In a procedure similar to that used in Asch's classic studies in 1946, 125 college students (54 men and 71 women, Mage=20.9 yr., SD=4.8) rated their impression of a hypothetical man or woman who was described by seven stimulus traits. This list included one of four central traits which appeared in the middle of the list: warm, cold, serious, or foolish. The dependent measures were factor scores derived from participants' ratings of 20 traits on social desirability and intellectual desirability. As hypothesized, warm and cold, prototypes of social desirability and undesirability, were associated with judgments of social but not intellectual desirability, and serious and foolish, prototypes of intellectual desirability and undesirability, were associated with judgments of intellectual but not social desirability. In addition, there was evidence of a subtle sex bias: ratings of "foolish" women were higher on social desirability than ratings of "foolish" men.
