Central intermittency: Some further observations

When the human subject is asked to respond to two stimuli separated by a very short time interval the response to the second stimulus may be relatively delayed. The present experiment is designed to test the hypothesis that the elements of the delay attributable to the sensory and motor components of the stimulus-response situation may be subserved by relatively independent neural mechanisms. The results obtained are compatible with this hypothesis and are briefly discussed.     

Some functions of the self personified by the father.

I have presented clinical material in order to illustrate a series of fantasies of parental intercourse which represent the self in successive stages of individuation from early projective identification to later introjective identification. From this is abstracted the idea of 'father' both as a component of the self representation and as the personification of the urge towards continuing development. Evidence is also gathered from the clinical material, supported by mythological parallels, to suggest that the whole process, including those components explicitly identified with the mother, is subsumed under an identification of the deintegrating self, its identity and integrity, with 'the father'.     

Intelligence and race: further comments on J. P. Rushton's work.

A review of some implications of J.P. Rushton's 1988 and 1990 work on racial differences in brain mass (size or weight) suggests that his comments do not constitute a viable scientific theory.     

Some comments on the role of cotherapists in group psychotherapy with borderline patients

This paper points out examples of patients in a psychotherapy group who meet DSM-III criteria for the diagnosis of borderline personality disorder and who are treated by cotherapists utilizing object relations theory. Interpretations of phenomena shown by borderline patients—splitting, projective identification and denial—are illustrated. How cotherapy lends itself to the recognition and management of the problems these patients bring to group psychotherapy is illustrated.Hope Aspell assisted in the editing of this paper.     

Chemical aversion conditioning in the treatment of alcoholism: further comments.

The literature on consummatory aversion (CA) conditioning in rats does provide a well-developed theoretical foundation for chemical aversion conditioning. Nevertheless, differences between rats and humans in CA learning suggest caution in extrapolating from the animal laboratory to the treatment of alcoholic patients. Serious methodological problems with studies of emetic therapy with alcoholics preclude unambiguous evaluation of its effects. Emetic therapy is an intrusive and relatively costly form of treatment which has not been shown to be more effective than alternative, less costly methods. The onus is on proponents of this method to demonstrate its specific advantages over alternative treatments.     

Some observations on the perception of Marroquin patterns.

Demonstrations are presented to show that the perception of structure in Marroquin patterns is disrupted if the dots comprising the pattern have opposite contrast polarity, and also if the dots comprising the pattern are separated in stereoscopic depth. It is also demonstrated that the perception of structure in a Marroquin pattern is made possible if the pattern is separated in stereoscopic depth from 'noise' dots, where the pattern structure cannot be perceived in either half of the unfused stereogram. In these respects the perception of Marroquin patterns is similar to the perception of Glass patterns. These findings are thus consistent with the proposal that the perception both of Marroquin and of Glass patterns is based on the construction of virtual lines.     

Some comments on Lehrer semantics

Lehrer Semantics, as it was devised by Adrienne and Keith Lehrer, is imbedded in a comprehensive web of thought and observations of language use and development, communication, and social interaction, all these as empirical phenomena. Rather than for a theory, I take it for a ??model?? of the kind which gives us guidance in how to organize linguistic and language-related phenomena. My comments on it are restricted to three aspects: In 2 I deal with the question of how Lehrerian sense can be empirically distinguished from Lehrerian reference as a precondition for the claim that sense relationships are in general more stable than reference relations. It seems that this very claim must already be presupposed for doing the respective empirical investigation. But in 3, I argue for the option to interpret the Lehrers?? concept of sense resp. sense vectors as intension concepts, by which move one may gain a generalized concept, so-to-say ??graded analyticity??, containing Carnapian strict analyticity for language systems as the extreme case of sense vectors with maximum value. Such graded sense may also be empirically investigated in the case of normal languages. In 4, I plead for my view that what the Lehrers take for communal languages are really collections of family-resembling idiolects of individual speakers and hypotheses of individual speakers about the idiolects of their fellow speakers. This move should free us from the fiction of, and sterile discussions about, the ??true?? meanings of words, but nevertheless keep normal language communication possible. As a concluding remark I propose in 5 to have both: normal languages from an empirical point of view, and codified languages from a logical reconstructionist one.
