Inventor perseverance after being told to quit: the role of cognitive biases

We find that approximately one third (29%) of independent inventors continue to spend money and 51% continue to spend time on projects after receiving highly diagnostic advice to cease effort. Using survey data from actual inventors, this paper studies the role of overconfidence, optimism, and the sunk‐cost bias in these decisions. We find that inventors are more overconfident and optimistic than the general population. We also find that optimism and past expenditures increased perseverance after being told to quit, while overconfidence in judgment ability had no effect. After being told to quit, optimists spend 166% more than pessimists and those having already spent, for example, $10 000 spend another $10 000. Copyright © 2007 John Wiley & Sons, Ltd.     

Calibration accuracy of a judgmental process that predicts the commercial success of new product ideas

We examine the accuracy of forecasts of the commercial potential of new product ideas by experts at an Inventor's Assistance Program (IAP). Each idea is evaluated in terms of 37 attributes or cues, which are subjectively rated and intuitively combined by an IAP expert to arrive at a forecast of the idea's commercialization prospects. Data regarding actual commercialization outcomes for 559 new product ideas were collected to examine the accuracy of the IAP forecasts. The intensive evaluation of each idea conducted by the IAP produces forecasts that accurately rank order the ideas in terms of their probability of commercialization. The focus of the evaluation process on case‐specific evidence that distinguishes one idea from another, however, and the corresponding neglect of aggregate considerations such as the base rate (BR) and predictability of commercialization for new product ideas in general, yields forecasts that are systematically miscalibrated in terms of their correspondence to the actual probability of commercialization.

Argumentation in and Across Disciplines: Two Norwegian Cases

This paper aims at exploring the challenges arising when teachers at secondary school level decide to cooperate about students’ argumentative writing. Two teams of teachers and researchers have met regularly during the school year, discussing students’ texts from a variety of disciplines. Going into two writing tasks in detail, the authors discuss the importance of scaffolding (support) in the teaching of argument. The paper includes a discussion of some specific textual features that are often touched upon in the meetings.     

Combined eyetracking and keystroke-logging methods for studying cognitive processes in text production

Writers typically spend a certain proportion of time looking back over the text that they have written. This is likely to serve a number of different functions, which are currently poorly understood. In this article, we present two systems, ScriptLog+TimeLine and EyeWrite, that adopt different and complementary approaches to exploring this activity by collecting and analyzing combined eye movement and keystroke data from writers composing extended texts. ScriptLog+TimeLine is a system that is based on an existing keystroke-logging program and uses heuristic, pattern-matching methods to identify reading episodes within eye movement data. EyeWrite is an integrated editor and analysis system that permits identification of the words that the writer fixates and their location within the developing text. We demonstrate how the methods instantiated within these systems can be used to make sense of the large amount of data generated by eyetracking and keystroke logging in order to inform understanding of the cognitive processes that underlie written text production.     

The normal distribution in scaling subjective stimulus differences: Less “normal” than we think?

The Gaussian, or “normal,” distribution is routinely used to model distributions of subjective quantities. This practice rests on a trust in the central limit theorem, yet this theorem does not cover the case of a mixture of Gaussian distributions with different standard deviations, which yields a distribution that is heavier tailed than the Gaussian. In psychophysical judgment experiments, this may result, for example, from fluctuating or interindividually varying attention. Two candidates for describing this commonly encountered type of distribution are the logistic distribution and thet distribution with a small number of degrees of freedom. In reanalyses of experimental data on three-category loudness comparisons, as well as in a Monte Carlo simulation,t(4) was found to model the underlying mixed inter- and intraindividual-distribution of subjective loudness differences quite satisfactorily.     

Living (dys)regulated and alienated young masculinity—Young men's embodied experiences of mental disorders and suicidality

Introduction

Mental disorders, such as depression and anxiety with interlinked suicidality, are the leading cause of health-related disability among young men. Knowledge of the interaction between emotional, bodily, social and gendered mental health processes in young men is limited and therefore needed.

Aim

This study aimed to explore young men's lived embodied experiences of mental disorders and suicidality, and to conceptualise these by integrating affective–emotional, physiological, social and gendered processes.

Methods

Semistructured individual interviews were conducted with 13 young men who had sought professional help for mental disorders and suicidality. Grounded theory (GT) was used with a social constructivist perspective.

Results

The results comprise one core category—Living (dys)regulated and alienated young masculinity—with related categories “battling with the emotional body,” “suffering in social silence” and “balancing embodied darkness and distress.” The GT illustrates how young men navigate and manage their embodied and emotional suffering in a context of “regulative” masculine and social norms alongside insufficient social support.

Conclusion

Our results suggest that young men's lived embodied experiences of mental disorders and suicidality can be understood as a dynamic process of internal and external “(dys)regulation and alienation.” The generated GT provides a broad tentative explanation model, contributing to theory development, and serves as a basis for gender-sensitive interventions—in both psychotherapy and physiotherapy—integrating body, mind and the social context.     

An Investigation of the Relationship between Age,Achievement, and Creativity in Mathematics

In this exploratory study, I investigate the relationship between age, knowledge, and creativity in mathematics, by looking at to what extent does grade level, controlled for mathematical achievement, influence mathematical creativity and what characterizes the relationship between grade level, mathematical achievement and mathematical creativity. This was accomplished in two steps. In the first part, 301 students, 184 grade eight students and 117 grade eleven students, were given a creative mathematics test. A 3 × 2 ANOVA indicates that the older students were more creative; however, there was a significant interaction effect between grade level and achievement in mathematics on mathematical creativity. In the second part, an inductive content analysis was performed on the solutions of high achievers in grade eleven and grade eight. The results indicate that high achievers in grade eight are more creative than high achievers in grade eleven, but the nature of the task mediates the relationship between creativity and knowledge.

The 2004 Indian Ocean Tsunami Catastrophe,its Survivors,Job and the Universal Features of Suffering: A Theoretical Study

The purpose of this theoretical article is to discuss the existential and universal feature of suffering—as illustrated by Job’s suffering in the Book of Job in the Bible and by the survivors of the 2004 Asian tsunami catastrophe—and to highlight its significance for health care. Further, the study is aiming at contributing to health professionals’ understanding of patients’ suffering. The sources are narratives, comprising Job’s book, TV interviews 1 year after the tsunami catastrophe and the survivors’ autobiographies. The methodological approach is a philosophical analysis. The existential, universal, ontological and epistemological aspects of suffering are carefully scrutinized to unveil the universal and existential versus culture-specific features of suffering. Based on the results, the authors’ recommendations are (1) a holistic concept of the patient and health care has to seriously consider suffering in all its complexity because when a person is in pain, it is not his/her body but the whole person as a unity of body, psyche and spirit that suffers and (2) suffering should be seen as the most central concept of health care, which should provide treatment for physical pain and all dimensions of suffering: physical, social, mental and spiritual aspects.     

The Trauma Related Shame Inventory: Measuring Trauma-Related Shame Among Patients with PTSD

This article proposes a new measurement instrument of trauma-related shame. The purpose of this study is to investigate the psychometric properties of the scores derived from the Trauma Related Shame Inventory (TRSI) by means of generalizability theory (G-theory). The psychometric analyses are based on a sample of 50 patients in treatment for Post-traumatic Stress Disorder (PTSD). The results provided supporting construct validity evidence for the interpretation of TRSI as a homogeneous construct. The 24-item version of internal and external referenced shame yielded generalizability and dependability coefficients of .874 and .868, respectively. The distinction between shame and guilt was supported by a high generalizability coefficient of .812 for the difference scores between TRSI and guilt cognition scale. Further validity evidence was provided by a positive relationship between TRSI and a) self-judgment subscale in Self-Compassion Scale (SCS; Neff Self and Identity 2:(3), 223–250, 2003) and b) Beck Depression Inventory (Beck Steer and Brown 1996a) when controlled for guilt. The results of the present study provided promising support for using the 24-item version of TRSI in both clinical research and practice.
