Should a school honor a student's DNR order? A lawyer responds: a student's right to forgo CPR.

...Instead of and certainly before advising the school or S.A. to go into court, I would urge them to try to resolve the question where it arises -- in the classroom, not the courtroom. And I would ask school officials to try to place themselves in S.A.'s shoes, and to imagine how she feels about her situation; and to ask themselves how they will feel if they administer CPR against her and her parents' wishes. Is there no way that they can do more than nothing, but less than CPR? Which image would we prefer to attach to S.A.'s case, that of some lawyers giving a press conference on the courthouse steps or of a story about a school that made it possible for one of its students to spend her precious time with her friends, classmates, and teachers, as they learn together that death does not need to separate the living from the dying?     

Ethics been very good to us

This commentary asks whether ongoing efforts to accredit, certify, and credential hospital ethics consultants are nothing other than an illegal restraint on trade masquerading as an effort to protect the public from harm.     

Teacher Acquisition of Functional Analysis Methods Using Pyramidal Training

Pyramidal training involves an experienced professional training a subset of individuals who, in turn, train additional individuals. Pyramidal training is effective for training a variety of behavior-analytic skills with direct-care staff, parents, and teachers. As teachers’ roles in behavioral assessment increase, pyramidal training may be useful to improve the procedural fidelity with which teachers conduct functional analyses. In the current study, previously trained teachers taught six other teachers (trainees) to conduct standard functional analysis conditions in a pyramidal training model. All trainees quickly acquired the skills necessary to conduct attention, escape, play, and tangible conditions during analog role-plays. Trainees also implemented functional analysis conditions with fidelity in their classrooms with students. Using a pyramidal training model may help to disseminate behavior-analytic procedures.     

Hide and seek: The theory of mind of visual concealment and search

Researchers have investigated visual search behavior for almost a century. During that time, few studies have examined the cognitive processes involved in hiding items rather than finding them. To investigate this, we developed a paradigm that allowed participants to indicate where they would hide (or find) an item that was to be found (or hidden) by a friend or a foe. We found that (i) for friends more than foes, participants selected the pop-out item in the display, and (ii) when the display was homogeneous, they selected nearby and corner items. These behaviors held for both hiding and finding, although hide and find behaviors were not identical. For pop-out displays, decision times were unusually long when hiding an item from a foe. These data converge on the conclusion that the principles of search and concealment are similar, but not the same. They also suggest that this paradigm will provide researchers a powerful method for investigating theory of mind in adults.     

Cognitive reappraisal reduces perceived exertion during endurance exercise

Emotion regulation may influence psychological responses to exercise. We examined whether the emotion regulation strategies, cognitive reappraisal and distraction, influenced psychological state and prefrontal cortex oxygenation during endurance exercise. Twenty-four endurance runners ran for 90 min at 75–85% maximum heart rate in three separate sessions with no instruction or with instructions to use cognitive reappraisal or distraction. Participants rated their emotional arousal, emotional valence, and perceived exertion before, every 30 min during, and after exercise. Functional near-infrared spectroscopy quantified changes in prefrontal cortex oxygenation. Participants felt lower emotional arousal and physical exertion when instructed to utilize cognitive reappraisal than when given no emotion regulation instruction. Such responses to distraction did not differ from the other conditions. Emotion regulation strategies did not influence emotional valence or prefrontal cortex oxygenation. Participants’ analytical interpretation of the cognitive reappraisal instruction could contribute to small effect sizes and limited effects. Further research should determine contexts under which emotion regulation strategies most benefit endurance exercise experience.     

Paradoxical Results and Item Bundles

Hooker, Finkelman, and Schwartzman (Psychometrika, 2009, in press) defined a paradoxical result as the attainment of a higher test score by changing answers from correct to incorrect and demonstrated that such results are unavoidable for maximum likelihood estimates in multidimensional item response theory. The potential for these results to occur leads to the undesirable possibility of a subject’s best answer being detrimental to them. This paper considers the existence of paradoxical results in tests composed of item bundles when compensatory models are used. We demonstrate that paradoxical results can occur when bundle effects are modeled as nuisance parameters for each subject. However, when these nuisance parameters are modeled as random effects, or used in a Bayesian analysis, it is possible to design tests comprised of many short bundles that avoid paradoxical results and we provide an algorithm for doing so. We also examine alternative models for handling dependence between item bundles and show that using fixed dependency effects is always guaranteed to avoid paradoxical results.
