Categorial grammars determined from linguistic data by unification

We provide an algorithm for determining a categorial grammar from linguistic data that essentially uses unification of type-schemes assigned to atoms. The algorithm presented here extends an earlier one restricted to rigid categorial grammars, introduced in [4] and [5], by admitting non-rigid outputs. The key innovation is the notion of an optimal unifier, a natural generalization of that of a most general unifier.     

Stability of the Millon Clinical Multiaxial Inventory among psychiatric inpatients

This study investigated the stability of the Millon Clinical Multiaxial Inventory (MCMI) in a sample of psychiatric inpatients over a longer time period and from different perspectives than previous reliability studies. Test-retest reliability was assessed from three perspectives: correlation/regression, equivalence of dimensional structures across testings upon different admissions, and stability of personality style across testings. Some stability from a correlational perspective was found, with higher stability estimates indicated for the basic personality scales in comparison with the clinical symptom scales which is consistent with Millon's theory. The internal structure of the MCMI was essentially identical across testings. Although source of reinforcement and instrumental or coping style were stable across testings beyond chance, the MCMI profiles of a considerable number of subjects were inconsistent across testings. Correspondingly, clinicians should be cautious in using the MCMI to make categorical decisions regarding personality style with inpatients who are tested at admission and who have had repeated hospitalizations.     

Brief report: Psychometric properties of the adaptive behavior scale with psychiatric inpatients

This study investigated the psychometric properties of the Adaptive Behavior Scale (ABS) with a sample of chronic psychiatric inpatients. Patients (N = 117) on extended care wards of a state hospital were assessed with the ABS. An orthogonal principal-components analysis revealed three underlying factors (independent functioning, general maladaptation, and inappropriate social behavior). Evidence for construct validity was demonstrated by analyses demonstrating that the ABS could discriminate among patients according to age, diagnosis, and length of hospitalization. The results are consistent with previous data which suggest that the ABS can be appropriately used with psychiatric patients. Implications of the results for suggestions regarding possible revision of the ABS are discussed.     

Ethology and psychoanalysis

Ethology has sometimes been considered a distant, perhaps quaint discipline which on occasion has peripherally enriched psychoanalysis. In contrast to this, it is suggested that the evolution of ethology, which is barely seventy years old, has, to a remarkable extent, mirrored the development of psychoanalysis. A comparison is made between the classical instinct concept in psychoanalysis and the classical ethological concept of instinct; and a parallel between the fate of the concept in each discipline is drawn. It is further suggested that the dialectical relationship and complementary evolution between ethology and psychoanalysis stems from both disciplines having introduced into an explanatory model of human behavior an element that was innate, instinctual, genetic—in short, biological.     

Effects of a school-based cognitive-behavioral intervention for ADHD children

Two variations of school-based cognitive-behavioral training (CBT) program were compared to each other and to a waiting-list control condition in the treatment of children with attention-deficit hyperactivity disorder (ADHD). The experimental interventions included a multicomponent condition that provided coordinated training programs for parents, teachers, and children and a teacher-only condition that offered training for classroom teachers only. Evaluation of outcome occurred at pre-intervention, post-intervention and at 6-week followup periods. Depedent measures included classroom behavior observations, teacher ratings of child behavior, child self-report, and teacher ratings of adjustment. The multicomponent CBT condition was significantly better than the other conditions at improving observed off-task/disruptive behavior at post-test. This improvement was maintained at followup, although treatment condition differences were no longer significant. There were no treatment condition differences on any other measures at postintervention or followup. It was concluded that the intervention had minimal short-term effects on the ADHD children. The results are discussed within the context of several methodological limitations of the study which serve as proposals for continued research in this area.The authors gratefully acknowledge the support and assistance of the faculty and staff at Echo Park, Cedar Park and Westview Elementary Schools (Rosemount, MN, Independent School District), and the parents and children who participated in this study. The authors would also like to extent special thanks to the principals of these schools, Mr. Robert Keaton, Mr. William Mack and Mr. Marvin Skinner, and the school psychologists servicing these schools, Ms. Sheila Peterson, Ms. Ann O'Brien, and Mr. Mark Kaloski, for their commitment and service to children with attention-deficit hyperactivity disorder.     

Belief, knowledge, and uncertainty: A cognitive perspective on subjective probability

This paper presents a cognitive analysis of subjective probability judgments and proposes that these are assessments of belief-processing activities. The analysis is motivated by an investigation of the concepts of belief, knowledge, and uncertainty. Judgment and reasoning are differentiated, Toulmin's (1958) theory of argument being used to explicate the latter. The paper discusses a belief-processing model in which reasoning is used to translate data into conclusions, while judgmental processes qualify those conclusions with degrees of belief. The model sheds light on traditional interpretations of probability and suggests that different characteristics of belief—likelihood and support—are addressed by different representational systems. In concluding, the paper identifies new lines of research implied by its analysis.
