Message Planning,Communication Failure,and Cognitive Load Further Explorations of the Hierarchy Principle

The hierarchy principle predicts and research has demonstrated that in response to communication failure, individuals make less cognitively demanding, low-level changes to message plans, such as the vocal intensity at which they are delivered, rather than more demanding alterations to message content and structure. Three experiments examined the effects of different message preparations on cognitive loads associated with high-level message plan alterations. In Experiment 1, individuals who prepared only one highly iconic message before experiencing communication failure demonstrated greater cognitive load when requested to deliver an alternative message than did individuals who prepared three highly iconic alternative messages. No cognitive load differences were found between those who prepared one or three low-iconicity messages. In Experiment 2, individuals who prepared one or six highly iconic message plans demonstrated greater cognitive load after communication failure than those who prepared three alternatives. This U-curve relationship was replicated in Experiment 3.     

Speaking about the Unspeakable: genocide and philosophy

ABSTRACT  Genocide is a political catastrophe. Yet it has not received much academic attention. A few social scientists have studied it. Philosophers have largely ignored it. There is a large literature on the Holocaust, but there is little agreement as to how this should be related to other genocides. Some have argued that the Holocaust represented a crisis of Western culture, but that Western culture has not responded adequately for the lack of the appropriate self-understanding. This crisis has been attributed to the predominance of scientistic models of rationality in our culture. Social-scientific approaches to genocide have been criticised because of their commitment to logical empiricism, which is held to be epistemologically and ethically inadequate. Ethical approaches based on liberal humanism have been criticised by post-Nietzschean philosophers for their attachment to allegedly outworn metaphysical assumptions. However, the deconstruction of social science and liberal ethics leads in the direction of relativism and nihilism, which are either useless or dangerous in the face of evils such as genocide. The arguments against conventional social science and ethics are examined, and a counter-critique made of post-modern philosophy in order to clear the ground for constructive thinking about genocide.     

Tonkens on the Irrationality of the Suicidally Mentally Ill

abstract   Ryan Tonkens proposes that my Kantian approach to suicide intervention with respect to the mentally ill (2002) wrongly assumes that the suicidally mentally ill are rational and are therefore rational agents to whom Kantian moral constraints ought to apply. Here I indicate how the empirical evidence concerning the suicidally mentally ill does not support Tonkens' criticism that the suicidally mentally ill are irrational. In particular, that evidence does not support the conclusion that such individuals are systemically practically irrational so as to undermine the attribution of at least minimal rational autonomy to them. A Kantian moral framework, albeit one developed in a non-ideal direction, remains applicable to such individuals.
