Visual and tactual form discrimination: Psychophysical comparison within and between modalities

Intermodal perceptual equivaience was investigated, using visual and tactual oddity discrimination and cross-modal matching-to-sample tasks. Four groups of Ss were presented with 100 problems made up of randomly derived forms from five levels of sidedness. The same quadratic relationship was observed for all tasks as a function of complexity, with optimal performance at eight sides. Comman information utilization, as indicated by intercorrelations of performance variables and by correlational analyses with differences in form measures, was not as pronounced within side classes. Evidence concerning the nature of pattern-feature usage in discrimination was obtained from graphical analyses.     

Functional equivalence between same-different classifications and judged similarity of Markov patterns

This experiment represented an initial at tempt at comparing same-different classifications and similarity judgments of Markov histoforms sampled from three different schema families. A measure of individual stimulus variability was more strongfy related to classification responses than to judged similarity. Dichotomous responses, derived from the similarity data by imposing threshold criteria, were found to be highly similor to real classification responses when the threshold values were estimated directly from the latter; little correspondence, however, was obtained using optimal classification criteria. The results support the notion that somewhat different features are used in making classification responses and similarity judgments, and indicate the need for developing more sensitive tasks involving controlled scanning of pattem information.     

The development of the menstrual symptom questionnaire

The literature has suggested that there are two separate types of primary dysmenorrhea with different physiological bases and different reported symptomatology. The purpose of this study was to construct a questionnaire based on suggestions from Dalton's (1969) theory of congestive and spasmodic types of primary dysmenorrhea, to obtain test-retest reliabilities of items, and to factor analyze the instrument to empirically investigate the two-type theory. The first set of 51 items had mean test-retest reliabilities of 0.76 and yielded two clearly distinct factors in support of the two-type hypothesis. When items with factor loadings less than ±0.35 were discarded, 25 items remained. The mean test-retest reliabilities of these items was 0.78. Again, two clearly distinct factors emerged defining congestive and spasmodic dysmenorrhea consistent with the literature. The retained items from the first questionnaire and the items from the second questionnaire loaded on the same factors both times. It was concluded that two types of dysmenorrhea do, in fact, exist and that this study has provided a reliable means of differentiating them. From a therapeutic standpoint, accurate diagnosis of type may be a prerequisite for prescribing appropriate treatment.     

Spatial interactions of taste stimuli on the human tongue

Two nearby loci on the human tongue were stimulated with solutions representing the four basic taste qualities. The recognition threshold for each test stimulus was measured when a strong concentration of one of the four qualities or water was placed nearby. Decreased sensitivity for the test stimulus resulted when both stimuli were the same quality, with the exception of an enhancement of bitter sensitivity by QHCl. The only effect across qualities was a suppression of citric acid by NaC1. In contrast, classical studies reported across-quality enhancement. Stimulation of two loci on the same half of the tongue and the use of modern psychophysical techniques may explain the differences between these and earlier results.     

Advancing the trait EI content domain: Further evidence for the distinctiveness of interpersonal facets

This investigation sought to assess the congruence of the trait emotional intelligence (EI) sampling domain, reflected in the short form of the Trait Emotional Intelligence Questionnaire (TEIQue; Petrides & Furnham, 2006), with the theoretical content of trait EI—namely, the range of personality traits implicated in emotions. First, associations of the TEIQue factors with Emotion-Oriented Coping (EOC) and Social Coping (SC) were compared. Three of the four TEIQue factors were stronger predictors of EOC than SC; only the Emotionality factor was a stronger predictor of SC. Also, Emotionality did not add to the prediction of EOC in a simultaneous regression with the other factors. Secondly, by means of Structural Equation Modelling, the 30-item composite and a theoretically altered 16-item composite were compared as mediators between the Big Five and the emotion-laden dimension of mental health. Even though all interpersonal items (i.e., those pertaining to Sociability and Emotionality) were omitted for the altered composite, it outperformed the original composite in predicting a latent mental health composite of Stress, Anxiety, and EOC. The results highlight the distinct nature of Emotionality and Sociability facets and have implications for the refinement of the trait EI content domain.     

The Relationship Between Adult Happiness and Self-Appraised Childhood Happiness and Events

The primary purpose of the present research was to relate questionnaire-assessed self-reported childhood happiness and events to adulthood happiness in 387 nonclinical participants. Although childhood happiness and adult happiness were found to be significantly correlated (r = .28, p < .001), there was little relationship between reported adult happiness and reported specific childhood events and circumstances. Childhood events and circumstances, however, were much more highly correlated with childhood happiness (R = .64). Thirty-four percent of the persons who said they were unhappy or very unhappy as a child, but only 9% who said they were happy or very happy as a child, reported that they were unhappy or very unhappy as adults.     

Toward making progress feedback an effective common factor in couple therapy

Systematic monitoring of individual therapy progress, coupled with feedback to the therapist, reliably enhances therapy outcome by alerting therapists to individual clients who are off track to benefit by the end of therapy. The current paper reviews the possibility of using similar systematic monitoring and feedback of therapy progress as a means to enhance couple therapy outcome, including what measures of therapy progress are most likely to be useful, how to structure feedback to be most useful to therapists, and the likely mediators of the effects of therapy progress feedback. One implicit assumption of therapy progress feedback is that clients unlikely to benefit from therapy can be detected early enough in the course of therapy for corrective action to be taken. As a test of this assumption, midtherapy progress was examined as a predictor of final couple therapy outcome in a sample of 134 distressed couples. Either a brief 7- or 32-item assessment of couple therapy progress at midtherapy detected a substantial proportion (46%) of couples who failed to benefit by the end of therapy. Given that failure to benefit from couple therapy is somewhat predictable across the course of therapy, future research should test whether systematic monitoring and feedback of progress could enhance therapy outcome.
