An addendum to the understanding and treatment of individuals with motivational deficits

A brief philosophical addendum to the traditional cognitive-behavioral treatment of individuals with motivational deficits is presented. A distinction is drawn between long-term desire, or motivation, and short-term willpower. It is asserted that willpower deficit is typically self-defined by individuals who report they do not wish to, and therefore believe they are unable to, act upon a previous commitment. In addition to utilizing the already-established strategies for treating these individuals, it is suggested that drawing the distinction between motivation and action can often serve to move unmotivated clients.     

Automated system for acoustic research

An automated system is described for stimulus presentation and response collection in psychoacoustic research. The system is capable of producing rapidly and precisely a wide range of discrete frequencies.     

Visual detection of signals in the presence of continuous and pulsed backqrounds

The detectability of intensity increments in the presence of continuous and pulsed backgrounds was investigated using a two-alternative, temporal, forced-choice procedure. Differences were found in intensity-duration reciprocity relations, the form of the Weber function, and the shape of the psychometric function between continuous- and pulsed-detection conditions. In a second study, signals were added either to a steady background (simple detection) or to background plus pedestal (pedestal detection). Two unusual phenomena were noted, namely, “negative masking” and the “pedestal effect.” The interpretation of the results in terms of a simple, Poisson-detection model is discussed.     

PUNISHMENT OF SELF-INJURIOUS BEHAVIOR USING AROMATIC AMMONIA AS THE AVERSIVE STIMULUS

Punishment with aromatic ammonia was used to eliminate self-injurious behavior of an autistic woman during experimental sessions. The effects were reversible but were limited to experimental sessions until staff used the ammonia on the ward at all times.     

Effects of two levels of stimulus complexity upon hypothesis sampling systems among second and sixth grade children

Groups of second and sixth grade children each solved a series of discrimination-learning problems involving four and eight dimensions that contained blanktrial probes for the S′s hypothesis (H). There were significant effects of grade level on three dependent measures (learning, generating consistent H patterns, sampling locally consistent Hs). Main effects of stimulus complexity were significant on five measures (the three above, rejecting disconfirmed Hs, maintaining confirmed Hs). There were no interactions involving any of these measures. The hypothesis sampling system (Sy) observed in each problem was also determined. Among sixth grade Ss this measure was unaffected by stimulus complexity level. Second grade Ss generated logically structured Sys in 65% of four-dimensional, but only 30% of eight-dimensional problems. They generated stereotyped behaviors or unsystematic sequences of Hs in 70% of eight-dimensional, but only about 35% of four-dimensional problems. Detailed analyses revealed that among second grade Ss good information processors (in terms of four component processes above) usually imposed a logical structure on four-dimensional, but generated unsystematic sequences of Hs in many of eight-dimensional problems. Poor processors generated stereotyped behaviors in both four- and eight-dimensional problems.     

The treatment of homosexuality by ‘assisted’ covert sensitization

Covert sensitization is a procedure which pairs imagined scenes of an unwanted behavior, such as homosexuality, with scenes aversive to the patient, in an effort to diminish the strength of a given response. It has been employed in the treatment of a host of maladaptive approach behavior (Cautela, 1967). However, only anecdotal or single-case reports (Barlow et al., 1969; Cautela, 1966, 1967; Gold and Neufeld, 1965) have appeared regarding the treatment of homosexuality, and these have been unanimously positive. It was disappointing, therefore, in applying this technique to homosexuals, to find it ineffective. One patient complained that the stimuli ‘were not strong enough’. Another could not adequately visualize noxious scenes. This report describes our development of a bolstered from of covert sensitization, demonstrates its application to the treatment of homosexuals and provides follow-up data to evaluate the adequacy of such treatment.
