An integral approach to health science and healthcare

Defining disease and delineating its boundaries is a contested area in contemporary philosophy of medicine. The leading naturalistic theory faces a new round of difficulties related to defining a normal environment alongside normal organismic functioning and to delineating a discrete boundary between risk factors and disease. Normative theories face ongoing and seemingly intractable difficulties related to value pluralism and the problematic relation between theory and practice. In this article, I argue for an integral—as opposed to a hybrid—philosophy of health based on Bernard Lonergan’s notion of generalized empirical method that provides a way to settle these difficulties dynamically and comprehensively, both in theory, by orienting functional and statistical investigation toward an explanatory ecological viewpoint, and in practice, by framing critiques in relation to the normativity intrinsic to all human inquiry.     

The generalized sense of power is a psychological resource: Evidence from a disaster response field training exercise

We examined whether the generalized sense of power—the belief that one is able to influence others in one's various social relationships—serves as a psychological resource that enables leadership in high-stakes, unfamiliar group challenges, such as emergencies or crises. We studied current and prospective humanitarian aid professionals (N = 180) during a major field training exercise: a three-day, immersive simulated humanitarian crisis. Individuals who entered the simulated crisis with a greater sense of power in their social relationships experienced lower stress (anxiety), behaved more assertively, and left the simulation with a relatively heightened desire to lead, despite not being deemed better leaders by their teammates. Lacking an initial sense of power was associated with experiences (e.g., feeling timid) that undermined the desire to lead. These results suggest that the psychological sense of power is a key leadership resource, without which one may be at risk of self-selecting out of leadership.     

L’adaptation transculturelle d’une échelle de mesure Cas de l’échelle des ancres de carrière

The objective of this research is to achieve a transcultural adaptation of a measure scale of professional values, particularly Schein’s (1985) career anchors from a north American context where it has been conceived to an arab-islamic culture, Tunisian’s environment. For this, this research follows a rigorous methodological process, that enable it to establish a new measure scale, offering good psychometric qualities and building up professional values adapted to Tunisian employees.     

Interpersonal Problem-Solving Skills Training in the Treatment of Self-Poisoning Patients

The present study evaluated the effectiveness of interpersonal problem-solving skills training (IPSST) for the treatment of self-poisoning patients. Thirty-nine self-poisoning patients were assigned randomly either to IPSST or to a control treatment condition (a brief problem-oriented approach). Both conditions were equally effective in reducing the number of presenting problems and in reducing hopelessness levels. However, the IPSST condition was significantly more effective than the control condition as determined by other outcome measures (measures of interpersonal cognitive problem solving, self-rated personal problem-solving ability, perceived ability to cope with ongoing problems, and self-perception). Follow-up studies showed maintenance of IPSST treatment gains at 6 months and a greater reduction of repetition of self-poisoning in the IPSST group at 1 year posttreatment.

Investigating virtual reality navigation in amnestic mild cognitive impairment using fMRI

Spatial navigation requires a well-established network of brain regions, including the hippocampus, caudate nucleus, and retrosplenial cortex. Amnestic Mild Cognitive Impairment (aMCI) is a condition with predominantly memory impairment, conferring a high predictive risk factor for dementia. aMCI is associated with hippocampal atrophy and subtle deficits in spatial navigation. We present the first use of a functional Magnetic Resonance Imaging (fMRI) navigation task in aMCI, using a virtual reality analog of the Radial Arm Maze. Compared with controls, aMCI patients showed reduced activity in the hippocampus bilaterally, retrosplenial cortex, and left dorsolateral prefrontal cortex. Reduced activation in key areas for successful navigation, as well as additional regions, was found alongside relatively normal task performance. Results also revealed increased activity in the right dorsolateral prefrontal cortex in aMCI patients, which may reflect compensation for reduced activations elsewhere. These data support suggestions that fMRI spatial navigation tasks may be useful for staging of progression in MCI.     

Categorization does not promote symmetry in Guinea baboons (<Emphasis Type="Italic">Papio papio</Emphasis>)

Humans have the capacity to use stimuli interchangeably by forming equivalence classes, and this ability seems to be supported by our language system. According to Sidman and Tailby (Conditional discrimination vs. matching to sample: an expansion of the testing paradigm. J Exp Anal Behav 37:5–22, 1982), the formation of equivalence classes require that three relations are derived among the class members, and past experiments have shown that one of these relations, i.e., symmetry, corresponding to the ability to reverse a relation (if A → B, then B → A), is extremely difficult to obtain in non-human animals. Because language development and the ability to form equivalence classes both co-occur in children with an increased ability to form categories, the current study tested the idea that category learning might promote symmetry in a nonhuman primate species. In Experiment 1, twelve Guinea baboons (Papio papio) were trained to associate 60 pictures of bears and 60 pictures of cars to two category labels, before being tested in symmetry trials. In Experiment 2, symmetry was trained and tested by reversing the association order between labels and pictures, using a new set of stimuli. In both experiments, the baboons successfully demonstrated category discrimination, but had only a weak (though significant) tendency to respond in accordance with symmetry during test trials. Altogether, our results confirm that symmetry is inherently difficult in non-human animals. We discuss possible explanations for such a limitation and give reasons for thinking that the effects of categorization on symmetry should be further investigated.
