The Relationship

The depressive-realism effect refers to a phenomenon in which depressed individuals are more realistic at assessing the relationship between two events than non-depressed individuals. Recent evidence suggests that the depressive realism hypothesis is weaker than first thought. Thus, we sought evidence for depressive-realism under conditions that we hypothesised would maximise the effect. We tested a clinically depressed sample of participants who were administered a rumination induction. Twenty-eight clinically depressed and 39 non-depressed participants were randomly allocated to either a rumination condition (focused on the causes, consequences, and meaning of their mood) or a distraction condition (focused on external objects/events such as a classroom). Participants then completed a contingency task in which there was no relationship between their responses and an outcome, and they were asked to make a judgment of how much control they had over an outcome. Both groups and conditions did not differ in their judgments of control; participants in all conditions showed a non-normative judgment of control. The depressive-realism effect was not observed in this study, even when depressed participants were encouraged to ruminate. Rather, the present study clearly demonstrates the robustness of the illusion of control.

The Relationship

This chapter utilizes cognitive theory to explain how entrepreneurial passion influences the speed of new venture's technology commercialization and explore the roles of cognitive bias (illusion of control and risk propensity) played in this process. The results show that both entrepreneurial passion and cognitive bias positively impact on the speed of technology commercialization. The authors also find that illusion of control and risk propensity play a partial mediating role in the relationship between entrepreneurial passion and the speed of technology commercialization. This conclusion can make up for the gap of existing theoretical research.

The Relationship

The purpose of this article is to investigate the relationship of overconfidence and illusion of control towards the start of new venture, taking in consideration the mediating role of risk perception in the context of Tunisia. This article examines students' responses to surveys based on a teaching case titled “Optical Distortion, Inc.” The authors tested hypotheses by correlation and regression analysis. The results show that the perception towards risk associated with new venture plays an important role in decision-making. Moreover, they find that overconfidence and illusion of control reduce risk perception associated to the decision to start a venture. While overconfidence directly affects the decision to start a venture and indirectly through its effect on reducing the risk perception, illusion of control has neither a direct nor an indirect impact on that. These results partially confirm those of Simon show that the mediation exists but partially.

The Relationship

By analyzing interpoint comparisons, we obtain significant results describing the relationship in “hippocampus shape space” of clinically depressed, high-risk, and control populations. In particular, our analysis demonstrates that the high-risk population is closer in shape space to the control population than to the clinically depressed population.

Objectives. The objective of this study is threefold: 1) to examine the effect of positive illusions on risk taking manifested in opportunity evaluation and investment decision; 2) to examine the mediating role of risk attitudes on the relationship between positive illusions and risk taking manifested in opportunity evaluation and investment decision; 3) to examine the moderating effect of experience on the relationship between positive illusions and risk taking manifested in opportunity evaluation and investment decision. Sample and setting. Research sample comprised 132 entrepreneurs aged between 19 and 63 (M = 40.6; SD = 10.8) owning small, medium, and large-sized businesses. Hypotheses. 1) Individuals exhibiting higher positive illusions (overconfidence, unrealistic optimism, illusion of control) would take higher risk manifested in opportunity evaluation and investment decision. 2) Risk attitudes will mediate the relationship between positive illusions and risk taking manifested in opportunity evaluation and investment decision. 3) Experience will moderate the relationship between positive illusions and risk taking manifested in opportunity evaluation and investment decision. Statistical analysis and results. 1) Using simple linear regression it was found that only unrealistic optimism for rare positive events and illusion of control predicted risk taking manifested in investment decision. None of positive illusions explained opportunity evaluation. 2) Using PROCESS macro for mediation analysis it was found that domain-specific risk perception, rather than general risk tolerance, is statistically significant mediator of the relationship between unrealistic optimism for rare positive events and investment decision. 3) Moderation analysis via PROCESS macro showed that only entrepreneurial experience moderates the relationship between unrealistic optimism for rare positive events and investment decision using own savings. The limitations concerning gender and domain specificity of methods are discussed in the study.

Sobre Todo

Tras los acontecimientos bélicos que asolaron el mundo durante el siglo XX, en concreto, a partid de 1980, aumento el interés y el acercamiento teórico sobre el pasado y la memoria. Partiendo de ello, la cuestión a tratar en el presente trabajo es: qué características tiene nuestro presente y cómo esto determina algunas formas de acceso al pasado. Para luego preguntarnos sobre la relación que se establece con los memoriales, es decir, en qué medida el contexto o condiciones del sujeto mediatizan su relación con la memoria. Dado que la reflexión acerca de la memoria puede estar condicionada por las características propias de nuestro contexto: aceleración social. El acercamiento que puede tener un sujeto perteneciente a las generaciones más alejadas de lo acontecido en el siglo XX difiere mucho de la relación que pueden tener aquellos que vivieron el suceso o las consecuencias de una forma más inmediata. Por ello, debemos preguntarnos: ¿Hemos -sobre todo las generaciones más jóvenes- volcado la memoria y el conocimiento en objetos externos a los que recurrir y de esa manera no llevar el peso y poder adaptarnos al contexto actual? Estos objetos portadores de la memoria y conocimiento, como las imágenes, internet, o los memoriales, etc. ¿Están sólo bajo una lógica del consumo inmediato?, o ¿es el tipo de uso más potenciado? ¿Qué relación establecemos con los memoriales? Monumentos creados con el fin de recordar. After the warlike events that devastated the world during the 20th century, specifically, from 1980, interest and the theoretical approach on the past and memory increased. Starting from this, the question to be dealt with in the present work is: what characteristics does our present have and how this determines some forms of access to the past. To then ask ourselves about the relationship that is established with memorials, that is, to what extent the context or conditions of the subject mediate his relationship with memory. Since the reflection on memory can be conditioned by the characteristics of our context: social acceleration. The approach that a subject belonging to the generations furthest away from what happened in the twentieth century may have differs greatly from the relationship that those who experienced the event or the consequences can have in a more immediate way. For this reason, we must ask ourselves: Have we - especially the younger generations - turned memory and knowledge into external objects to turn to and thus not carry the weight and be able to adapt to the current context? These objects that carry memory and knowledge, such as images, the internet, or memorials, etc. Are they only under a logic of immediate consumption? Or is it the most enhanced type of use? What relationship do we establish with the memorials? Monuments created in order to remember.

The Relationship

The term ‘risk management’ implies that risk is something which can be quantified, predicted and controlled. This paper seeks to demonstrate the limits of this assumption where complex projects are involved. The argument is based upon a case study of a failed £80 million IT venture known as Taurus. Analysis focuses upon the relationship between politics and the assumption of risk. Acceptance of risk, it is argued, is ultimately determined by the balance of power between decision makers. Moreover, risk analysis and other techniques of management may actually compound the difficulties by fostering an illusion of control and escalation. The implications for project management are discussed.

The Relationship

The Objective of the study is to investigate the relationship of overconfidence bias and illusion of control bias towards the start of new venture, with the mediating role of risk perception in context of Pakistan. To understand the relationship, this study developed and tested hypothesis by correlation and regression analysis. This study’s sample consisted of 170 students pursuing a Masters of Business Administration. The students’ responses to a survey based on a case study regarding a decision to start a venture were examined. This study found illusion of control and risk perceptions have significant effect on decision to start new venture. Conversely, overconfidence bias has insignificant relationship with decision to start new venture. The positive and negative impact of biases and perceiving low levels of risk suggest the importance of exploring the area of venture formation. As this study has incorporated two biases but many other biases should also be considered that effect human decision making process like self-efficacy, availability heuristics, law of small numbers and escalation of commitment.

Objectives The relationship between dimensionally assessed personality and the onset, features, and course of depressive illness will be critically examined and considered in relation to 4 hypothesized models: predisposition or vulnerability; pathoplasty; complication or scar; and spectrum or continuity. Method Studies that have used clinically depressed adult patients to explore the relationship between personality dimensions and depression will be reviewed. Results Higher-order personality factors that have shown a significant and consistent association with major depressive illness include neuroticism, extraversion (negative relationship), and the factors of Cloninger's Tridimensional Personality Model. Neuroticism appears to be the most powerful predictor of depression. Lower-order factors showing a significant and consistent relationship with depressive illness include dependency, self-criticism, obsessionality, and perfectionism. The links between depression and dependency and self-criticism have the strongest empirical support. Conclusions Several personality dimensions are significantly associated with depressive illness, but the evidence that unequivocally demonstrates a true personality predisposition for depression is modest. Measures of personality may prove to be clinically useful for treatment selection.
