The Köhler Group Motivation Gain: How to Motivate the ‘Weak Links’ in a Group

A recurring question of successful group work is how to maintain high task motivation of the individual members. This paper reviews research on one well documented group motivation gain phenomenon, where group members are more highly motivated than comparable individual performers – the Köhler motivation gain effect. The basic effect is attributed to two psychological mechanisms, one involving upward social comparisons and a second involving the indispensability of group members’ efforts. In addition to summarizing research on the discovery and causes of the basic effect, this review identifies probable moderators of each contributing causal mechanism. Moreover, promising topics for future research as well as implications for the application of the Köhler effect in real group work are discussed.     

Telehealth Monitoring of Patients with Schizophrenia and Suicidal Ideation

A telehealth system was developed to monitor risk following hospitalization for suicidal ideation. We hypothesized that 3 months of telehealth monitoring will result in a greater reduction in suicidal ideation. Veterans with schizophrenia admitted with recent suicidal ideation and/or a suicidal attempt were recruited into a discharge program of VA Usual Care with daily Health Buddy© monitoring (HB) or Usual Care (UC) alone. Fifteen of 25 were randomized to HB and 10 received UC. Daily adherence in the use of the HB system during months 1–3 was, respectively, 86.9%, 86.3%, and 84.1%. There were significant improvements in Beck Scale for Suicide Ideation scores in HB participants. There were no changes in depressive symptoms. Telehealth monitoring for this population of patients appears to be feasible.     

Transubstantiation after Wittgenstein

Catholic doctrine of the eucharist is commonly thought to incorporate a metaphysical theory of substance. Wittgenstein subverts such theories. Elizabeth Anscombe and Michael Dummett, much respected post-Wittgensteinian philosophers, who are also deeply committed Catholics, argue that substance/accidents metaphysics as well as modern transignification theories prevent the religious events to stand on their own: the moment of consecration, the reservation of the consecrated elements. Bad theories which occlude the religious realities are thus removed—which does not show that all philosophizing about religious doctrine must be "rubbish".
