Semantic Holism is seriously false

Semantic Holism is the claim that any semantic path from inferential semantics (the indeterminate semantics forced by the classical inference rules of PC) reaches all the way to classical semantics if it is even one step long. In our joint paper Semantic Holism, Belnap and I showed that some such semantic paths are two steps long, but we left open a number of questions about the lengths of semantic paths. Here I answer the most important of these questions by showing that there are infinitely long semantic paths that begin at inferential semantics but that do not even reach classical semantics. I do this by showing how to construct such an infinite semantic path from the members of the family of (n–1)-out-of-n-disjunction connectives.     

Comorbidity of ADHD and reading disability among clinic-referred children

Of a consecutive series of 115 boys diagnosed in a university outpatient clinic as ADHD, 39% also demonstrated a specific reading disability. Pure ADHD patients were compared with mixed ADHD + RD and normal controls on a battery of cognitive and attentional measures. The aim was to determine whether a distinct pattern of deficits would distinguish the groups. Both ADHD subgroups performed significantly worse than controls on measures of sequential memory and attentional tasks involving impulse control andplanful organization. Only ADHD+RD boys differed from controls on measures or rapid word naming and vocabulary. The reuslts are discussed within the framework of an automatic versus effortful information-processing model.     

A COMPARATIVE STUDY OF RECIDIVISTS AND CONTRACEPTORS ALONG THE DIMENSIONS OF LOCUS OF CONTROL AND IMPULSIVITY

The research examined personality differences between repeat aborters, initial aborters, and nulliparas. A review of the literature in the area has documented the demographic characteristics of women who continually seek repeated abortion. This study was an attempt to differentiate between women who contracept from those who seek abortion repeatedly on the basis of personality differences. The findings indicate that repeaters who seek abortion at the time of personality testing perceive themselves low in impulsivity, a finding similar to that for women who have never been pregnant and are seeking contraceptive services. Results are examined from the perspective of inaccurate vs accurate self-perceptions. No differences were found with respect to locus of control.     

Toward a value diffusion theory of depression

Unlike psychoanalytic theory, which claims that loss of a valued relationship, role, or goal trigers a trauma of infancy or childhood involving separation from the mother, value diffusion theory describes the relationship between loss and depression differently: First, loss precipitates a destabilization of values (specifically, “continuity” and “discontinuity” values) that form a part of the character of an individual; second, if the destabilization persists and is of sufficient severity, value diffusion, a state in which the individual actually experiences a loss of identity or self, occurs, which often produces a state of depression. The author draws attention to a direct relationship between concepts underlying a value diffusion theory and psychoanalytic theory of depression. Psychoanalytic theorists have noted the special significance of two kinds of loss producing depression: (1) a loss of relationships, and (2) a loss of achievements. In value diffusion theory, the first of these corresponds to one of a set of values to which the author has given the name “continuity” values in prior publications, and the second to one of a set of values given the name “discontinuity”. A case study is presented of an elderly depressed woman to illustrate certain aspects of value diffusion theory, and to contrast it with psychoanalytic and learned helplessness theory as causal explanations of depression.     

The Vocational Exploration Group and minority youth: An experimental outcome study

This study was designed to investigate experimentally the effectiveness of the Vocational Exploration Group in assisting students to become more aware of the world of work and its relevance for them. Sixty male, Mexican-American, junior high students were randomly assigned to one of three groups: (1) Vocational Exploration Group, (2) VEG without interaction, or (3) Control. Upon completion of treatments subjects were post-tested with an instrument designed to assess knowledge of factors such as differing functions of jobs, interests and skills needed in different jobs and satisfactions available from work. Analyses revealed no statistically significant differences (a = .05) among groups.
