A modification of kendall's tau for measuring association in contingency tables

A coefficient of association is described for a contingency table containing data classified into two sets of ordered categories. Within each of the two sets the number of categories or the number of cases in each category need not be the same.=+1 for perfect positive association and has an expectation of 0 for chance association. In many cases also has –1 as a lower limit. The limitations of Kendall's _a and _b and Stuart's _c are discussed, as is the identity of these coefficients to' under certain conditions. Computational procedure for is given.     

Suggestion reduces the stroop effect

We examined the effects of suggestion on Stroop interference in highly suggestible individuals. Participants completed the Stroop task with and without a suggestion to perceive Stroop words as meaningless symbols. Half the participants were given this suggestion in hypnosis, and half were given the suggestion without the induction of hypnosis. Suggestion produced a significant reduction in Stroop inhibition, accounting for about 45% of the variance in Stroop responding, regardless of whether hypnosis had been induced. These findings indicate that suggestion can at least partially overcome the automaticity associated with the Stroop effect.     

Conditioning, expectancy, and the placebo effect: comment on Stewart-Williams and Podd (2004)

Classical conditioning is included as a component in the response expectancy model of placebo responding. Though introspectable when attention is drawn to them, expectancies need not be in awareness while guiding behavior. Most placebo effects are linked to expectancies, and classical conditioning is one factor (but not the only factor) by which these expectancies can be produced and altered. Conditioned placebo effects without expectancies exist but are relatively rare in humans. The adaptive advantage of cognition is increased response flexibility. For it to convey that benefit, however, it must be capable of overriding the influence of simpler automatic processes. Thus, the higher up the phylogenetic scale, the smaller the role of nonconscious conditioning processes and the larger the role of cognition.     

The shifting sands of a professional identity

I decided while an undergraduate that I wanted to be a psychologist. Beyond that, I'm still not sure what I'll do when I grow up. This brief autobiography maps the shifting sands of my professional identity: from psychotherapist to developmental psychopathologist and then to primary concerns with education and training, from psychologist to academic administrator and then back again, to forensic psychologist and on to whatever may come next. Through all of these shifts in focus, however, there has been one recurring theme--the appeal of being an assessment psychologist. The events that kept bringing me back to assessment, whatever else my focus at the time, are recorded in the story that follows.     

Why are therapists indifferent to research?

In counselling and psychotherapy there is a serious research—practice gap. Why should research on the therapeutic process have such little impact? Five related factors are considered: (i) epistemology—reliance on experiential/personal knowledge; (ii) preciousness—reliance on nonaxiomatic truths; (iii) lack of theoretical rigour—looseness with which constructs are construed; (iv) non-Popperian logic—tendency to work within a theory and defend it; and (v) personalisation of theory—evaluation seen as criticism. The result is a proliferation of therapies rather than a refinement of therapy.     

Hope and Coping with Cancer by College Women

The relations of dispositional hope to various self-reported cancer-related coping activities were examined in 115 college women. Dispositionally high- as compared to low-hope women were more knowledgeable about cancer, and this relationship remained when the shared variances due to previous academic achievement, experience with cancer among family or friends, and positive and negative affectivity were removed. Additionally, high- as compared to low-hope women reported more hope-related coping responses in four separate imagined phases of cancer (prevention/risk, detection, temporal course, and impact), and these relationships remained when shared variances related to previous academic achievement, knowledge about cancer, experience with cancer, and negative affectivity were removed. Hope is discussed as means of maintaining a "fighting spirit" for coping with cancer.
