We read with interest the paper written by Savaris et al. entitled “Stay-at-home policy is a case of exceptional fallacy: an internet-based ecological study”[1]. We believe that the topic of whether non-pharmaceutical interventions (NPIs) have an impact on COVID-19 mortality is a key metric that is important to measure, and applaud the authors for attempting to do so. However, we believe that several key deficiencies within the methodology make the conclusions – that the authors found no evidence that COVID-19 deaths were reduced by staying at home – largely meaningless. In this letter we explain the deficiencies in the analysis, and why the methodology may be inadequate to detect an effect even if it were to exist.

Goals are a central feature of narratives, and, thus, narratives may be particularly potent means of goal priming. Two studies examined two features of goal priming (postdelay behavioral assimilation and postfulfillment accessibility) that have been theorized to distinguish goal from semantic construct priming. Across the studies, participants were primed with high achievement, either in a narrative or nonnarrative context and then completed either a behavioral task, followed by a measure of construct accessibility, or a behavioral task after a delay. Indicative of goal priming, narrative-primed participants showed greater postdelay behavioral assimilation and less postfulfillment accessibility than those exposed to the nonnarrative prime. The implications of goal priming from narratives are discussed in relation to both theoretical and methodological issues.

Abstract. Psychotherapy is an effective treatment for most mental disorders, including anxiety disorders. Successful psychotherapy implies new learning experiences and therefore neural alterations. With the increasing availability of functional neuroimaging methods, it has become possible to investigate psychotherapeutically induced neuronal plasticity across the whole brain in controlled studies. However, the detectable effects strongly depend on neuroscientific methods, experimental paradigms, analytical strategies, and sample characteristics. This article summarizes the state of the art, discusses current theoretical and methodological issues, and suggests future directions of the research on the neurobiology of psychotherapy in anxiety disorders.
