Toward a differential testing approach: Testing-the-limits employing the Raven matrices

Various testing-the-limits procedures were employed in administering the Raven Coloured Progressive Matrices Test to 203 second grade and 230 fourth grade children. Tests of impulsivity, neuroticism, extroversion, intelligence and school achievement were also given. The main results showed that testing-the-limits procedures which involved verbalization and feedback were efficacious in maximizing performance on the Raven. The puzzle form of the test generally led to higher scores than the picture version for the second but not fourth graders. Differential analyses were carried out to establish how construct, concurrent and predictive validity of the Raven were affected by the salient testing-the-limits procedures involved. Analysis was also done with the personality variables and revealed how their effect interacted with various test administration procedures. The results were discussed in theoretical and practical terms.     

Consistency in attitude and behavior of women with a liberated attitude toward the rights and roles of women

The study was designed to determine the extent of consistency of attitude and behavior of women with liberated attitudes toward their rights and roles, and to identify determinants of inconsistency between attitude and behavior. The Attitude Towards Women Scale, Rotter's locus of control scale, the Ego-Strength Scale, the Self-Esteem Scale, the Liberated Behavior Questionnaire, and the Attitude of Family and Friends Questionnaire were administered to 242 women. Women with more liberated attitudes tended to act more liberated. Also, women with liberated attitudes tended to act more liberated if their close friends were liberated and if they themselves were more aware of leaders in the women's liberation movement. The personality measures did not relate to the tendency to act liberated.     

Transfer of persistence to the acquisition of a new behaviour

Two experiments tested whether the degree of effort required for the reinforcement of one behaviour would affect the acquisition of a second behaviour. In the first experiment, rats were placed in a conditioning chamber and: (a) were required to press a lever for food pellets on a fixed ratio schedule, (b) received free presentation of the pellets, or (c) did not receive pellets. Next, all rats were rewarded for a new behaviour, round trips across the length of a runway. As predicted, the fixed-ratio group had the greatest shuttle rate. In the second experiment, two groups were required to press a lever, and the number of presses per pellet was varied. For two other groups not required to press the lever, the amount of food presented per approach to the feeder was varied. The greater required number of lever presses and the lesser number of pellets per approach to the feeder produced the higher subsequent shuttle rates. Two alternative explanations were compared: the degree of accustomed effort per reinforcer becomes a learned component of behaviour, or high effort increases the habituation of frustration-produced disruptive responses.     

The stability and reliability of attentional bias measures in the dot-probe task: Evidence from both traditional mean bias scores and trial-level bias scores

Motivation and Emotion - A new method of calculating attentional bias from the dot-probe task measures fluctuations in bias towards and away from emotional stimuli over time using trial level bias...     

The Presumption of Nothingness

Several distinguished philosophers have argued that since the state of affairs where nothing exists is the simplest and least arbitrary of all cosmological possibilities, we have reason to be surprised that there is in fact a non-empty universe. We review this traditional argument, and defend it against two recent criticisms put forward by Peter van Inwagen and Derek Parfit. Finally, we argue that the traditional argument nevertheless needs reformulation, and that the cogency of the reformulated argument depends partly on whether there are certain conceptual limitations to what a person can hypothetically doubt.     

Honoring and Privileging Personal Experience and Knowledge: Ideas for a Narrative Therapy Approach to the Training and Supervision of New Therapists

This article discusses an approach for the training and supervision of new therapists built around social constructionist and poststructuralist ideas from a narrative therapy perspective. We briefly discuss some of the pitfalls of current training/supervision in marriage and family therapy (MFT) that are deficit based and/or that disproportionately grant privilege to expert knowledge. We articulate this emerging training approach which utilizes the rite of passage metaphor, centers relationalism, and incorporates the honoring and privileging of new therapists' lived experience, knowledges, skills, talents, ideas, morals, personal ethics, values, beliefs. Concrete practices of experience privileging, re-membering, and creating communities of concern are detailed, and illustrative examples from our supervision work are given.
