Boston Naming Test: problems with administration and scoring

The poorly written administration and scoring instructions for the Boston Naming Test allow too wide a range of interpretations. Three different, seemingly correct interpretations of the scoring methods were compared. The results show that these methods can produce large differences in the total score.     

A Critique of Langsam's “The Theory of Appearing Defended”

In this paper we consider, and reject, Harold Langsams defenceof the Theory of Appearing, in this journal (1997), in the faceof three standard arguments against it. These arguments are:the argument from hallucination; the argument from the samecause-same effect principle; and the argument from perceptualtime-gap.     

Correlations among measures of cognitive ability, creativity, and academic achievement for gifted minority children

This study explored the correlations among nonverbal reasoning ability, creativity, and academic achievement in gifted minority children, 89 girls and 71 boys in Grades 1 through 8 in a program for gifted. A random half of students from all grade levels were tested at the beginning of the year and the remaining half after 7 mo. with Raven Progressive Matrices, Torrance Tests of Creative Thinking, and the California Achievement Test. Pearson correlations reflected limited relations among these variables except for a significant positive value between creativity and reading achievement. Suggestions for further study and implications for identification procedures and program development were provided.     

Criticisms of the criminal justice system: A decision making analysis

When a decision making analysis is applied to key decisions within the criminal justice system, e.g., bail, sentencing, and plea bargaining, a wide range of evidence suggests that the decision makers believe they follow policies other than those that actually guide their decisions; that the policies that are followed are often simple ones, involving only a few decision factors; and that the decision outcomes are often assigned to defendants in a reasonable manner but that, even so, the outcomes are often ineffective. Because many proposals for the reform of the criminal justice system are based on the testimony of decision makers and “experts” whose knowledge of the system is often flawed, it is unlikely that reforms will have a beneficial impact on criminal behavior until much more is known about the day-to-day decisions of judges, prosecutors, and probation officers.     

The completeness of the factor semantics for Łukasiewicz's infinite-valued logics

In [12] it was shown that the factor semantics based on the notion ofT-F-sequences is a correct model of the ukasiewicz's infinite-valued logics. But we could not consider some important aspects of the structure of this model because of the short size of paper. In this paper we give a more complete study of this problem: A new proof of the completeness of the factor semantic for ukasiewicz's logic using Wajsberg algebras [3] (and not MV-algebras in [1]) and Symmetrical Heyting monoids [7] is proposed. Some consequences of such an approach are investigated.     

Transcortical motor aphasia: One or two aphasias?

The name "transcortical motor aphasia" has been used to refer to two different types of language alterations: damage in the left supplementary motor area and Luria's dynamic aphasia. It is proposed that they represent two types of language disturbances different enough to be considered two different forms of aphasia.
