Information processing in chronic pain disorder: A preliminary analysis

Researchers have alternately suggested selective attention, impaired stimulus filtering, and affective language deficiency models as accounting for multiple somatic complaints in persons with chronic pain disorder. The purpose of the present study was to establish the comparative usefulness of these three models for explaining somatic focus in a chronic pain population. Nine chronic pain patients evidencing high somatic focus (somatizing chronic pain patients), 10 chronic pain patients evidencing low somatic focus (nonsomatizing chronic pain patients), and 10 healthy control subjects were administered a computerized version of the emotional Stroop test as a test of these models. A total of 105 pain-, depression-, and neutral-content words were used as Stroop test stimuli. Stroop test color-naming response latencies were submitted to a two-way Group × Word Type mixed-model ANOVA, with Word Type as the repeated measure. Results reveal that neither the selective attention model nor the affective language deficiency model adequately explain Stroop test performance in somatizing chronic pain patients. Findings provide tentative support for the impaired stimulus filtering model, with somatizing chronic pain patients evidencing similar Stroop test response delays across all words. These results suggest that chronic pain sufferers misinterpret bodily sensations. Findings are discussed in terms of a bilevel approach for treatment of somatizing chronic pain patients that would include assisting the patient in accurate appraisal and interpretation of physical symptoms.     

Affective information processing and the assessment of anxiety

A conceptualization of anxiety as comprising three loosely coupled response systems of overt behavior, verbal report, and physiological activation has proven useful in clinical and theoretical work. With this framework as a starting point, an information-processing approach to the study of emotion is described. Emotions are conceived as affective programs within the brain, with information coded as propositions organized into associative networks. Affective expression results when such a network is accessed and processed, which can occur when a sufficient number of propositions are activated by environmental stimuli and/or internal associations. It is hypothesized that information about the expressive physiology is an integral component of the associative structure, and that processing of the network accordingly results in measurable psychophysiological response. Data from studies of emotional imagery, as well as other areas of research, are reviewed in support of these theories. The utility of this approach for the assessment of anxiety disorders is discussed, and results of clinical studies are presented to suggest that individual differences in accessing and processing emotional information may bear significant implications for prognosis and treatment selection. It is speculated that differences among the anxiety disorders could be interpreted in terms of the degree of cognitive organization of the network, leading to potential refinement of current diagnostic categories. In conclusion, cognitive psychology paradigms are discussed in terms of their application to the assessment and treatment of anxiety disorders.The authors' research is supported in part by NIMH Grant MH 37757. Portions of this paper were presented at the NIMH Conference on Anxiety, Tuxedo, NY, September 1983. Several of its themes were developed there at more length, and this material may be found in the publication of the conference proceedings (Tuma & Maser, 1985).     

Spatial and temporal relations in conditioned reinforcement and observing behavior

In Experiment 1, depressing one perch produced stimuli indicating which of two keys, if pecked, could produce food (spatial information) and depressing the other perch produced stimuli indicating whether a variable-interval or an extinction schedule was operating (temporal information). The pigeons increased the time they spent depressing the perch that produced the temporal information but did not increase the time they spent depressing the perch that produced the spatial information. In Experiment 2, pigeons that were allowed to produce combined spatial and temporal information did not acquire the perch pressing any faster or maintain it at a higher level than pigeons allowed to produce only temporal information. Later, when perching produced only spatial information, the time spent depressing the perch eventually declined. The results are not those implied by the statement that information concerning biologically important events is reinforcing but are consistent with an interpretation in terms of the acquisition of reinforcing properties by a stimulus associated with a higher density of primary reinforcement.     

Swedish and English secondary school pupils' attitudes towards, and conceptions of, bullying: concurrent links with bully/victim involvement

Thirteen and fifteen year old Swedish and English secondary school pupils (n = 210) completed a questionnaire designed to measure attitudes towards, and conceptions of, bullying. The older participants also provided peer nominations of classmates thought to be bullies and victims. Significant differences between pupils from the two countries, between younger and older pupils, and between girls and boys emerged on a number of these variables. For example, a significantly larger percentage of English pupils than Swedish pupils indicated that name calling is bullying, whereas the reverse was true for leaving somebody out. These results suggest that findings concerning incidence of, and beliefs about, bullying may not generalise from one group of pupils to another. Overall, participants tended to express anti-bullying attitudes. The present results also add to the small but growing set of findings which suggest that pupils' attitudes concerning bullying and their actual involvement in bullying are associated concurrently. Attitudes were found to significantly predict involvement in bullying even after the variance shared with participants' sex had been controlled. Specifically, those pupils that expressed the weakest anti-bullying attitudes were found to be most often nominated by peers as a bully. The implications of these results for anti-bullying interventions were discussed.     

Biases in Visual Attention in Children and Adolescents With Clinical Anxiety and Mixed Anxiety-Depression

Recent research has indicated that anxious adult and child patients and high trait-anxious adults selectively shift attention toward threatening stimuli. The present study extends this research and investigates the content-specificity of the effects in clinically anxious and mixed anxious–depressed children and adolescents. Twenty four generally anxious patients, aged 9 to 18, 19 mixed anxious–depressed patients, and 24 normal controls were comparable with respect to age, sex, verbal IQ, and vocabulary level. The participants carried out an attentional deployment task in which probe detection latency data were used to determine the distribution of visual attention for threat-related and depression-related material. The results showed that clinically anxious children, relative to controls, selectively allocated processing resources toward threat stimuli. However, mixed anxious–depressed children, relative to controls, did not show any attentional bias towards either threat- or depression-related stimuli. Preliminary data on age and gender differences are also presented. The results of this study are discussed in the light of previous research.

Argument Quality and Cultural Difference

Central to argumentation theory is a concern with normativity. Argumentation theorists are concerned, among other things, with explaining why some arguments are good (or at least better than others) in the sense that a given argument provides reasons for embracing its conclusion which are such that a fair- minded appraisal of the argument yields the judgment that the conclusion ought to be accepted -- is worthy of acceptance -- by all who so appraise it.This conception of argument quality presupposes that the goodness of arguments is characterizable in terms of features of the argument itself. It makes no reference either to the attributes of the persons appraising the argument and judging its normative force, or to the context in which that appraisal is carried out. But recent work by a wide range of philosophers, argumentation theorists, and social theorists rejects such an abstract, impersonal notion of argument goodness. Instead, these theorists insist upon taking seriously, in the evaluation of arguments, the features of the evaluators themselves. In particular, such theorists emphasize the importance of cultural difference in argument appraisal. Often locating themselves under the banner of multiculturalism, they argue that the quality of an argument depends upon culturally-specific beliefs, values, and presuppositions; that an argument may be of high quality in one cultural context but of low quality in another. Consequently, they contend, no abstract, impersonal characterization of argument quality can succeed.In this paper I consider this multiculturalist approach to argument quality. I argue that while there is much merit in the general multiculturalist perspective, the multiculturalist argument against impersonal conceptions of argument quality fails. It fails for several reasons detailed below; most fundamentally, it fails because it itself presupposes just the kind of impersonal account of argument quality it seeks to reject. I call this presupposition that of transcultural normative reach. I identify this presupposition in the multiculturalist argument, and show how it undercuts the multiculturalist challenge to abstract, impersonal, transcultural conceptions of argument quality. I conclude with an evaluation of the strengths, and weaknesses, of the multiculturalist challenge to such conceptions of argument quality.
