Interleaving reading and acting while following procedural instructions

Memory for an interactive procedure acquired from written instructions is improved if the procedure can be carried out while the instructions are being read. The size of the read-act cycle was manipulated in Experiments 1 and 2 by comparing chunked instruction-following, in which 3 or 4 steps are read then performed with single-step conditions. In both experiments, enforced chunking improved subsequent unaided performance of the procedure. In Experiment 3, participants were allowed to manage the interleaving of reading and acting. The imposition of a small behavioral cost (a single mouse point-and-click operation) on the switch between instructions and device encouraged more chunking and better subsequent test performance. The authors concluded that the interleaving of reading and acting is an important practical concern in the design of interactive procedures and that more effective chunk-based strategies can quite readily be encouraged.     

Using Counselor Training and Collaborative Programming Strategies in Working With International Students

This article offers an overview of the adjustment concerns of international students in the United States and explores venues for inclusion of this population in multicultural training and counselor competency development opportunities for graduate students. Counselor educators need to provide awareness and knowledge about the issues faced by international students within graduate course work and training models. This will ensure that counselor trainees are competent within a multicultural framework to understand the unique issues of international students and respond by providing culturally sensitive counseling services and programming. A model of programming implemented at a private university that provided a training opportunity for counselors‐in‐training is highlighted. Considerations in designing collaborative programs are also discussed. Este artículo da un resumen de las preocupaciones de ajustamiento de estudiantes intemacionales en los Estados Unidos y explora avenidas para incluir esta población en el entrenamiento y desarollo multicultural de estudiantes de consejería. Educadores de consejeros necesitan proveer consciencia e información sobre las situaciones enfrentadas por estudiantes intemacionales en el entrenamiento de estudiantes graduados. Esto asegurara la competencia multicultural de los estudiantes para que así entiendan las necesidades unicas de los estudiantes intemacionales y puedan proveer sensibilidad cultural en la consejería y programación de servicios. Este artículo describe un modelo de programación implementado en una universidad privada que entrenó a estudiantes de consejería. Además se discuten consideraciones para el diseño de programas colaborativos.     

Counting bones: environmental cues that decrease food intake

At an all-you-can eat buffet in a sports bar, it was tested whether people would eat less if they knew how much they had already eaten. 50 graduate students (34 women; M age = 24.1 yr.) were seated at 21 tables randomly assigned to be bussed (leftover wings removed) or unbussed (wings left on table). The 31 students at the bussed tables ate more than those at the unbussed tables (7 wings vs. 5.5 wings), with the effect being stronger for men than women. In distracting eating environments, environmental cues may provide an effective means of reducing consumption. Implications for controlling alcohol intake were also noted.     

A controlled evaluation of group cognitive therapy in the treatment of irritable bowel syndrome

We randomized, at two sites, 210 patients with Rome II diagnosed irritable bowel syndrome (IBS), of at least moderate severity, to one of three conditions: group-based cognitive therapy (CT; n=120), psychoeducational support groups (n=46) as an active control, or intensive symptom and daily stress monitoring (n=44). One hundred eighty-eight participants completed the initial treatment. Those in symptom monitoring were then crossed over to CT. For an intent to treat analysis on a composite GI symptom measure derived from daily symptom diaries, both CT and the psychoeducational support groups were significantly more improved than those in the intensive symptom monitoring condition, but the CT and psychoeducational support group did not differ. Among treatment completers on the same composite measure of GI symptoms, again, both CT and psychoeducational support groups were statistically superior to symptom monitoring but did not differ on the symptom composite, or on any other measure. On individual IBS symptoms, both CT and psychoeducational support were statistically superior to symptom monitoring on reductions in abdominal pain and tenderness and for flatulence. Patient global ratings at the end of treatment showed the two active conditions statistically superior to symptom monitoring on change in Bowel Regularity, with CT superior to symptom monitoring on reduction in overall pain and in improvement in sense of well-being. Three-month follow-up data on 175 patients revealed maintenance of significant improvement or continued significant improvement on all IBS symptoms, including the McGill Pain Questionnaire. Group CT and psychoeducational support groups continued not to differ on any measure. We thus conclude that group CT is not superior to an attention placebo control condition.     

Down with the Hierarchies

Evidence hierarchies are widely used to assess evidence in systematic reviews of medical studies. I give several arguments against the use of evidence hierarchies. The problems with evidence hierarchies are numerous, and include methodological shortcomings, philosophical problems, and formal constraints. I argue that medical science should not employ evidence hierarchies, including even the latest and most-sophisticated of such hierarchies.
