Bilateral tachistoscopic word perception of stutterers and normal subjects

Bilateral tachistoscopic procedures were utilized to investigate the visual half-field preferences of 15 stutterers and a group of 15 normal controls. Statistical analyses indicated a right visual half-field preference for the control group. In contrast, a significant visual half-field preference was not revealed for the stuttering group. However, further analysis revealed that a significantly larger proportion of stutterers, compared to controls, demonstrated a left visual half-field preference. Results indicated reversed cerebral processing for the stuttering group as compared with the control group.     

A Multitrait-multimethod examination of Minnesota Multiphasic Personality Inventory (MMPI) and Millon Clinical Multiaxial Inventory (MCMI)

Recently, certain Minnesota Multiphasic Personality Inventory (MMPI) and Millon Clinical Multiaxial Inventory (MCMI) scales have seen increasing usage for the measurement of DSM-III personality disorders. The current study sought to identify the convergent and discriminant validity of these two sets of scales for this purpose. In general, the results indicated significant convergence across the two instruments. However, better convergent validity was found for scales representing those DSM-III disorders which are most consistent with the typology upon which the MCMI was based. In particular, convergent and discriminant validity results were poorest for Compulsive, Antisocial, and Passive-Aggressive personality scales.     

The fallacy of fallacies

Several of the so-called fallacies in Aristotle are not in fact mistaken inference-types, but mistakes or breaches of rules in the questioning games which were practiced in the Academy and in the Lyceum. Hence the entire Aristotelian theory of fallacies ought to be studied by reference to the author's interrogative model of inquiry, based on his theory of questions and answers, rather than as a part of the theory of inference. Most of the fallacies mentioned by Aristotle can in fact be diagnosed by means of the interrogative model, including petitio principii, multiple questions, babbling, etc., and so can Aristotle's alleged anticipation of the fallacy of argumentum ad hominem. The entire Aristotelian conception of inquiry is an interrogative one. Deductive conclusions caught Aristotle's attention in the form of answers that every rational interlocutor must give, assuming only his own earlier answers. Several features of Aristotle's methodology can be understood by means of the interrogative model, including the role of endoxa in it. Theoretically, there is also considerable leeway as to whether fallacies are conceived of as mistakes in questioning or as breaches of the rules that govern questioning games.     

Relationships between the Beck Depression Inventory and the Hamilton Psychiatric Rating Scale for Depression in depressed outpatients

The Beck Depression Inventory (BDI) and the Hamilton Psychiatric Rating Scale for Depression (HRSD) were used with 300 outpatients diagnosed with DSM-III major depression disorders. A principal-components analysis was performed on the intercorrelations among the 21 BDI and 24 HRSD symptoms. Three orthogonal components were found and interpreted as reflecting differences in self-report and clinical rating methods for measuring the severity of depression. The importance of using both self-reports and clinical ratings for evaluating depression in psychiatric outpatients was discussed.     

The topics in medieval logic

The topics is a theory of argumentation based upon topoi or in Latin loci. The medieval logicians used works by Aristotle and Boethius as their sources for this doctrine, but they developed it in a rather original way. The topics became a higher-level analysis of arguments which are non-valid from a purely formal point of view, but where it is none the less legitimate to infer the conclusion from the premiss(es). In this connection the topics give rise to a number of discussions about the form and the matter of arguments. Further the topic contribute to the elaboration of the important doctrine of the second intentions, i.e. higher-level concepts of the particular things. In some respects the topics may be said to form a link between formal and informal logic. The topics vanished as a part of logic at the end of the Middle Ages, perhaps because the medieval logicians never got rid of Boethius' claim to have compiled a complete list of the loci, which was an unlucky one. The topics does not have an exact parallel in modern formal logic, but some reflections on non-formal argumentation by recent authors contain certain resemblances to it.     

Correspondence in children's self-report: Tacting and manding aspects

Four boys and 4 girls (3 to 5 years old) played with as many as three toys chosen from a set of six, and were then asked whether they played with each of the toys. After a baseline in which all children showed high levels of correspondence between reported and actual behavior, reports of play were differentially reinforced, first in an individual and then in a social context. Two children in the individual condition began to report play with all six toys, even though no more than three toys had been played with. When reports of play were reinforced in a group context, 5 children reported play with all six toys. When correspondence was subsequently reinforced, virtually complete correspondence returned and was maintained in a third noncontingent reinforcement condition. Correspondence and lack of correspondence were discussed in terms of self-tacting and distorted tacting or manding.     

An improved solution for factals: A nonmetric common factor analysis

In FACTALS an alternating least squares algorithm is utilized. Mooijaart (1984) has shown that this algorithm is based upon an erroneous assumption. This paper gives a proper solution for the loss function used in FACTALS.     

From dispositions to behaviors: The flip side of attribution

The implicational relations between dispositional levels and relevant categories of behavior were investigated. Observers were asked questions about the extent to which persons occupying moderate or extreme positions on an attribute (dispositional) continuum (a) attempt various behaviors, (b) are potentially able to perform various behaviors, and (c) generally emit those same behaviors. Three determinants—central tendency, ability, and social desirabliity—offer a reasonable account of the observed implicational relations. First, persons with a given disposition are not expected to emit behavior that is widely discrepant with that disposition. Second, ability considerations dictate that persons with skillful dispositions are believed capable of unskillful behavior, but unskillful persons are thought relatively incapable of skillful behavior. Third, persons are believed to more frequently attempt socially desirable than socially undesirable behavior. Also, persons with moderate dispositions are believed to actually emit socially desirable behavior more frequently than socially undesirable behavior. Finally, the determinants noted above may be of differing relevance for morality, ability, and preference attributes.     

Olfactory dysfunction in man: anatomical and behavioral aspects

We reviewed studies examining the olfaction of patients with brain damage for the purpose of discerning correlations between disordered structure and function. Patient samples included those with neurological disorders and neurosurgical interventions and recording of spontaneous or elicited neuronal activity. Brain areas involved in olfaction include the olfactory bulbs, the orbitofrontal and medial temporal cortices, the thalamus, and the amygdala. Despite recent advances in olfactory anatomy, understanding of how these structures are related to olfactory detection, discrimination, and recognition continues to be limited. Inadequate localization of brain lesions and lack of comprehensive behavioral assessment have thus far prevented a detailed account of the organization of olfaction in the human brain.
