StopPulling.com: An Interactive, Self-Help Program for Trichotillomania

Despite the widespread nature and significant impact of trichotillomania (TTM), relatively few controlled studies have evaluated treatment options for people with this disorder. Pharmacological treatment and behavior therapy are the two most widely accepted approaches to treating TTM, but few mental health professionals with appropriate expertise are available to provide care. The cost of treatment also is prohibitive in some cases. A number of self-help books are available for people with TTM, but no empirical data have documented associated outcomes. This paper describes the development and two phases of program evaluation for an alternative, Internet-based self-help treatment strategy for repetitive hair pulling. StopPulling.com is an on-line, interactive self-help approach derived from evidence-based cognitive behavioral models of treatment for TTM. Following program development, an initial test phase elicited feedback from individuals with repetitive hair pulling and professionals with expertise in the treatment of TTM or Web site development. StopPulling.com was modified in accordance with feedback from this initial test phase, and a revised version was made available to the public in January 2003. Preliminary data from 265 users of the program during the first year of public availability suggested significant improvement in symptoms, with some evidence that duration of program use accounted for reductions in symptom severity. Response rates were comparable to long-term follow-up after more intense cognitive behavioral treatment. StopPulling.com may provide a potentially useful self-help alternative or adjunctive strategy for repetitive hair pulling.     

Lana Chimpanzee Learns to Count by “Numath”: A Summary of a Videotaped Experimental Report

This paper summarizes a videotaped presentation (Rumbaugh, Savage-Rumbaugh, Hopkins, Washburn, & Runfeldt, 1987) of computerized training programs whereby an adult female chimpanzee, Lana (Pan troglodytes), learned to use a joystick to remove from a screen the number of boxes appropriate to the value of a randomly selected Arabic numeral 1, 2, or 3. Initial training provided a variety of cues, both numeric and otherwise, to support correct performance. Across software programs, all cues other than numeric ones were deleted. In the final test, Lana was correct on over 80% of trials in which there was no residual feedback of intratrial events and where only her memory of those events could provide the cue to indicate that she had removed boxes in accordance with the value of the target numbers and should terminate the trial. The tape is narrated and consists of video recordings of Lana's performance on each software program.     

Integration and eclecticism in counselling and psychotherapy: Cautionary notes

Obstacles on the path to integration and eclecticism are illustrated in three realms of endeavour: the therapeutic relationship, the constitution of knowledge, and visions of reality. The strands of three major systems of psychotherapy - the psychoanalytic, the behavioural and the humanistic - are examined as to the desired nature of the therapist-client relationship, their sources and understanding of data, and the worldviews they encompass from among the romantic, ironic, tragic and comic. Differences among these theories of psychotherapy are seen to limit the possibilities for integration and eclecticism. This conclusion is tempered, however, by a recognition of the value of each approach assimilating some views of the others in a considered way.     

Running laboratory experiments using the RSX operating system and FORTRAN on the PDP-11

A system of FORTRAN-callable subroutines designed to facilitate running laboratories with the RSX operating system on a PDP-11 computer is presented. The subroutines include ones to give the FORTRAN programmer timing capability, better control of CRT input and output, control of a parallel-bit input and output interface, control of an analog-to-digital interface, and control of a digital-to-analog interface.     

GROUP TRAINING OF CONSERVATION SKILLS WITH CHILDREN FROM A NON-TECHNOLOGICAL CULTURE*

Group training of conservation of length was undertaken with primary school children in Botswana. Each group contained 10 subjects of mixed academic ability. Three methods of training were used: (1) teacher demonstration accompanied by responsive group recitation, (2) limited manipulation of training materials by students, (3) full manipulation of training materials by students. The three training methods were effective in producing learning, retention, and generalization of conservation. The results are discussed in terms of Piaget's views on the role of environmental influences and the function of action in the development of cognitive structures. The value of Piagetian concepts for non-technological societies also is discussed.     

Computerizing the perception laboratory: Surviving the transition

A number of problems may be encountered during the transition to a computerized perception laboratory. Although some of these problems are of a technological nature, others have to do with the psychology of the investigator. These problems are discussed in the context of actual incidents taken from various research facilities, and some suggestions for avoiding common difficulties are presented.     

AN EVALUATION OF THE RELATIONSHIP BETWEEN RECEPTIVE SPEECH SKILLS AND EXPRESSIVE SIGNING

We examined the effects of receptive speech on the acquisition of manual signing among three mentally retarded children. In an alternating treatments design, we compared the acquisition of expressive signs that were, versus were not, in a child's receptive vocabulary. The children were trained via total communication in which pictorial referents were named during sign training. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. We conducted posttests to assess the stimulus control of signing and any changes in expressive and receptive signing and speech. Observed changes in performance could be accounted for by attention to aspects of the stimulus complex during training and functional equivalence of stimuli established by training.
