The biological paradigm of psychosis in crisis: A Kuhnian analysis

The philosophy of Thomas Kuhn proposes that scientific progress involves periods of crisis and revolution in which previous paradigms are discarded and replaced. Revolutions in how mental health problems are conceptualised have had a substantial impact on the work of mental health nurses. However, despite numerous revolutions within the field of mental health, the biological paradigm has remained largely dominant within western healthcare, especially in orientating the understanding and treatment of psychosis. This paper utilises concepts drawn from the philosophy of Thomas Kuhn to explore the impact of what Kuhn terms 'anomalies' within the dominant biological paradigm: the anomaly of the meaningful utterance, the anomaly of complex aetiology and taxonomy and the anomaly of pharmacological inefficacy in recovery. The paper argues that the biological paradigm for understanding psychosis is in crisis and explores the implications for mental health nursing.

Psychological and actual group formation: Conflict is neither necessary nor sufficient

Conflict is neither necessary nor sufficient for the existence of groups. First, the existence of mutually supporting, rather than antagonistic, interactants is sufficient to constitute a "social group." Second, conflict does not necessarily mark group boundaries but can also exist within an ingroup. Third, psychological representations of social groups do not only trace, but also perpetuate the existence of groups.

Activism as a heroic quest for symbolic immortality: An existential perspective on collective action

Excellent research exists on the conditions that generate political and social activism. Yet a central issue has remained perplexing: how does the personal need to stand out as unique and heroic interact with the concern for the positive image of the group, and the desire to protect and bolster its status, goals and shared values, in propelling collective action? Inspired by existential theory and research, this paper proposes an existential perspective on activism that identifies the human desire for a sense of meaning and significance as an important motivation underlying individuals' choice to engage in collective action. This study outlines an integrative model of collective action, combining insights from existential psychology with insights from the social identity perspective, to bridge together needs and concerns associated with both personal identity and group identity into a single model of collective action through the concept of death-anxiety buffering mechanisms. This model suggests that collective action is an effective means to satisfy existential needs through bolstering and protecting group interests and values on the one hand, and realizing the activist's heroism project on the other. Suggestions for future research are discussed.
