Theor of free choice permission

I argue that the conjunctive distribution of permissibility over or, which is a puzzling feature of free-choice permission is just one instance of a more general class of conjunctive occurrences of the word, and that these conjunctive uses are more directly explicable by the consideration that or is a descendant of oper than by reference to the disjunctive occurrences which logicalist prejudices may tempt us to regard as semantically more fundamental. I offer an account of how the disjunctive uses of or may have come about through an intermediate discourse-adverbial use of or, drawing a parallel with but, which, etymologically, is disjunctive rather than conjunctive and whose conjunctive uses seem to represent just such a discourse-adverbial application.     

The preservation of coherence

It is argued that the preservation of truth by an inference relation is of little interest when premiss sets are contradictory. The notion of a level of coherence is introduced and the utility of modal logics in the semantic representation of sets of higher coherence levels is noted. It is shown that this representative role cannot be transferred to first order logic via frame theory since the modal formulae expressing coherence level restrictions are not first order definable. Finally, an inference relation, calledyielding, is introduced which is intermediate between the coherence preservingforcing relation introduced elsewhere by the authors and the coherence destroying, inference relation of classical logic.     

Cerebral lateralization of visual stimulus recognition in stutterers and fluent speakers

Cerebral lateralization of stutterers and nonstutterers was assessed in terms of choice reaction times to stimuli presented to either the left or right visual hemifield on letter recognition and figure recognition tasks. Reaction times on both tasks were determined before and after a behavioral speech therapy program. Stutterers demonstrated a significant reduction in mean reaction times in the letter recognition task over the course of the therapy program. This change differed significantly from that obtained from stutterers in the figure recognition task. The stutterers' responses were in contrast to the responses of the nonstutterers, who showed no reduction in mean reaction times for the letter or figure recognition tasks. The results were discussed in terms of alterations in aspects of central nervous system processing as a result of participation in the behavioral speech therapy.     

A technique for rapid,reliable assessment of thermal-pain threshold in humans

A simple and reliable method of assessing pain threshold in humans may be useful in a number of research areas, such as in examining acute antinociceptive effects of drugs. We have developed a low-cost, computer-controlled method to reliably assess thermal-pain threshold using radiant heat focused from a slide projector and applied to a small area of skin. An electronic shutter is attached to the projector opening to provide precise onset and offset of heat. A computer keypad allows for subject response at the point of pain onset (i.e., threshold), with latency to threshold determined by computer timer. The details of the apparatus setup, subject preparation, and instructions to subjects are presented. The development of the method is described, and sources of unreliability are identified. Coefficients of variation (CVs) are calculated to provide a measure of variability within subjects across trial exposures and across sessions. Results indicate that the method is reliable for determining pain threshold, especially within sessions, and can be employed with relatively minimal expense and subject preparation.     

A measure of linear influence between patient and therapist.

This paper describes the application of the cross-correlation function (CCF) to four quantified dimensions of the therapeutic consultation dialogue: newness of themes, degree of narration, and positive and negative thematic tone of images. A 10-min. window was used to study lag relationships in both directions of effect--from therapist to patient and the reverse. This measure of linear influence was applied to six psychotherapeutic consultation sessions carried out by different well known psychoanalysts with two women patients. Analysis showed a range of significant CCF effects that totaled from zero to 1360 sec. depending on the consultation. The implications of these and other findings are discussed in the context of viewing the present study as part of a program of investigations into the nonexperimental nature--the underlying laws, structures, and transactions--of therapeutic and everyday emotional dialogues.     

Type A behavior and reminiscence in college undergraduates

This study represents the first empirical test of Friedman and Ulmer's (1984. Treating Type A behavior and your heart. New York: Fawcett) clinical observation that deficits in the capacity to reminisce about pleasant past events are among the most pervasive and dysfunctional correlates of Type A behavior. Type A (N = 79) and B (N = 109) college undergraduates completed a questionnaire assessing the frequency, content, style, and consequences of their reminiscence about positive past experiences. Findings supported two hypotheses: relative to Type Bs, Type As were less likely to report that they consciously look back on positive events after these events are over in order to store details for later recall, and were more likely to report that they typically reminisce about past achievements. Contradicting Friedman and Ulmer's observations, however, there were no significant A/B differences in the reported frequency, style, or consequences of recalling positive memories. The findings are discussed in terms of components of Type A behavior, such as competitive achievement-striving and self-esteem enhancement, that may make Type As (a) less likely to store, but not to recall, positive memories and (b) particularly likely to reminisce about personal accomplishments. Plausible reasons for the relative lack of support for Friedman and Ulmer's hypotheses are discussed in the context of directions for future research.     

Retaliatory equity as a factor in humor appreciation

Squelches depicting a protagonist who is provoked and who then retaliates against his provoker were manipulated to effect a variation in the degree of retaliation achieved: extreme underretaliation, underretaliation, fair retaliation, overretaliation, and extreme overretaliation. It was proposed that retaliatory equity, i.e., a situation in which the negative consequences inflicted upon the provoker by the retaliator are of a similar magnitude to the negative consequences initially inflicted upon the retaliator, constitutes an optimal condition for mirth, and that both types of retaliatory inequity, under- and overretaliation, impair humor appreciation in proportion to the magnitude of the resultant inequity. The findings fully supported these propositions.     

Assessing support networks: Stability and evidence for convergent and divergent validity

Data on important methodological problems in assessing support networks is presented. Stability (over 1 year) and construct validity were examined in two groups of mothers of preschool children. One group of mothers had children with a physical handicap (n = 25); the other group had normally developing children (n = 44). When their children were 4 years of age and again at 5 years of age, mothers' support networks were assessed with the Pattison Psychosocial Kinship Inventory (a semistructured interview) and a log diary. Results indicated considerable stability in mothers' support networks over the 1-year period. In addition, agreement across methods was fairly high despite marked differences in format, providing evidence for the construct of support networks. Further evidence for construct validity was provided by generally low correlations between support network variables and other measures of social ecology. Findings were roughly similar for both groups of mothers indicating general replicability of findings.
