The high prevalence of brain injury incidents in adolescence and adulthood demands effective models for re-learning lost cognitive abilities. Impairment in brain injury survivors’ higher-level cognitive functions is common and a negative predictor for long-term outcome. We conducted two small-scale interventions (N = 12; 33.33% female) with persons with acquired brain injuries in two municipalities in Sweden. Age ranged from 17 to 65 years (M = 51.17, SD = 14.53). The interventions were dialogic, inquiry-based, and inspired by the Philosophy for (...) Children Programme, a participatory thinking skills approach with documented higher-order cognitive outcomes, such as developed argumentation skills, in other target groups. Philosophical dialogues were conducted once a week in the two groups, totalling 12 dialogues per group. Group argumentation development was measured through compared scores from structured observations of filmed dialogues early and late in the intervention. Large positive changes in mean scores from early to late in the intervention, together with constantly high facilitator quality, suggest argumentation development in the sample due to the intervention.

Annually, more than ten million people in all age groups in the world experience an acquired brain injury, which is a brain injury caused after birth by external forces or certain internal factors. Brain injury survivors are often left with long-term impairments in cognitive, social, or emotional functioning. Despite a promising outset, research on the effectiveness of philosophical dialogues as an educational method for persons with ABI to increase their cognitive, social, and emotional functioning has, to our knowledge, been virtually (...) non-existent. The present research project targets this and uses a pretest-posttest and mixed-method triangulation design and attempts to measure effects of two small-scale interventions carried out in the northern part of Sweden. In this text, the project’s research design, data production, and data processing are described. (shrink)
