Requiem for “schizophrenia”

In this article a brief overview of the treatment of chronic psychosis for the last two centuries is covered, with particular emphasis on many scientifically demonstrated causes of chronic organic psychosis and their medically successful treatment, including recent neurotransmitter manipulations. With respect for the important contributions of Bleuler, the term “schizophrenic” is considered as an unscientific and unprovable nosological construct, which has hampered the successful resolution of chronic psychosis and has outlived its usefulness in the lexicon of modern psychiatry.     

The measurement of imagery ability

When variations in imagery ability are used to predict task performance, distinct and consistent relationships do not tend to emerge. A selective review of studies is undertaken to outline some basic reasons why individual difference measures of imagery are often so unsuccessful. Relevant studies concerning the learning and performance of motor skills are examined in some detail. It is concluded that the major problem in these studies is the types of imagery tests that have been employed; these tests have not adequately measured imagery ability. A recently developed instrument, the Movement Imagery Questionnaire, which has been designed to assess individual differences in visual and kinesthetic imagery of movement is discussed.     

Completely nonmetric multidimensional scaling

Most of the distance models underlying multidimensional scaling assume that if a stimulus y is between the stimuli x and z on each dimension, then x and z should be the farthest apart of the three stimuli. An iterative algorithm is described that uses only this betweenness prediction to infer the ordering of a set of stimuli on each of one or two dimensions. Applied to previously published semantic similarity data, this algorithm produced two-dimensional configurations that were similar in appearance to Euclidean configurations but generally involved fewer violations of the betweenness prediction.     

Reduction of sadistic sexual arousal by olfactory aversion: a case study

A sexual sadist was treated by an olfactory aversion procedure for eight weeks. Pre-treatment assessment of sexual arousal showed high levels of response to sadistic stimuli as well as high arousal to non-sadistic heterosexual stimuli. In treatment the inhalation of the gas of an odoriferous chemical agent, valeric acid, was paired with slide presentations of sadistic materials while penile erection was monitored. The aversive stimulus immediately and permanently suppressed the response for the duration of treatment. In separate measurement sessions, with valeric acid absent, deviant response remained suppressed and nondeviant response was unaffected. Post-treatment reassessment revealed very low levels of response to sadistic stimuli. Follow-up sessions showed that the deviant response was absent eight months following the conclusion of treatment.     

Using Self-Supervision to Maintain Counseling Skills: A Review

Counselor education literature acknowledges the difficulty of skill maintenance but offers few solutions. A review of related areas was conducted to provide direction in developing maintenance strategies. Four domains were considered: maintenance in behavior modification, behavioral self-control, the traditional maintenance mechanisms of feedback, supervision, and observational media, and self-supervisory programs. A self-supervisory program that applies the procedures of behavioral self-control to specific helping behavior that is identifiable on audiotape or videotape is advocated.     

Parameters for vowel substitutions in Broca''s aphasia

Most phonological investigations of aphasic speech have focused on consonants. In this study, the vowel substitutions of five English-speaking Broca's aphasics were investigated with respect to several major explanatory hypotheses. An important possible motivating factor for aphasic substitutions, phonological environment, is an unlikely origin for these errors, since most substitutions occur along the paradigmatic axis. Another prominent hypothesis, markedness, also has no predictive power for the data of this sample. However, an analysis of the five Chomsky and Halle (1968, (The Sound Pattern of English), New York: Harper and Row) vowel features indicates that the two features for vowel height are selectively impaired: There is a strong tendency for lower vowels to replace higher targets. Moreover, the substitution sounds tend to be close to their target sounds along the height axis. Four possible hypotheses are advanced to account for this consistent lowering tendency.
