Whether the decision is to have unprotected sex, consent to surgery, have an extra piece of pie, or spend rather than save for retirement, risky decisions permeate our lives, and sometimes with disastrous consequences. How and why risk taking occurs has important implications. Yet many questions remain about how neurobiological, psychological, and socio-cultural factors influence decision-making. This book advances basic understanding and scientific theory about the brain mechanisms underlying risky decision by integrating findings from a number of disciplines, including development and cognitive psychology, brain sciences, law, behavioral economic, and addiction. The result is a rich scientific framework for understanding the causal mechanisms of risky decision making across the lifespan. Book jacket.

Risky Decision Making in Psychological Disorders provides readers with a detailed examination of how risky decision making is affected by a wide array of individual psychological disorders. The book starts by providing important background information on the construct of risky decision making, the assessment of risky decision making, and the neuroscience behind such decision making. The Iowa Gambling Task, Balloon Analogue Risk Task, and other behavioral measures are covered, as are topics such as test reliability and the pros and cons of utilizing tasks that have strong practice effects. The book then moves into how risky decision making is affected by specific psychological disorders, such as addictive behaviors, anxiety disorders, mood disorders, schizophrenia, sleep disorders, eating disorders, and more. Explores how risky decision making is affected by different psychological disorders Examines risky decision making and ADHD, psychosis, mood/anxiety disorders, and more Synthesizes the research on risky decision making Discusses merits/limitations of the Iowa Gambling Task and other behavioral measures Covers risky decision making and its associations with other executive functions

In the current study, we examined the effects of priming and personality on risky decision making while playing the Game of Dice Task (GDT). Participants were randomly assigned to one of three priming conditions: Risk Aversive, Risk-Seeking, or Control. In the Risk Seeking condition, a fictional character benefited from risky behavior while in the Risk Aversive condition, a fictional character benefited from exercising caution. In the GDT, participants decide how risky they wish to be on each trial. To optimize performance, one should make "safe" rather than risky choices. Although older adults self-reported being more cautious than younger adults, older adults made riskier decisions than younger adults on the GDT. However, there were no longer significant age differences on the GDT after controlling for working memory. More than likely, the aforementioned age differences were due to age-related changes in effective strategy usage, rather than age-related changes in the propensity to take risks. In addition, for young adults, certain personality traits significantly predicted risky decision making on the GDT. The findings from this study have implications for older adults' decision making in everyday situations. Older adults may make risky decisions and thereby jeopardize their financial and other resources, not because they intentionally want "to roll the dice," but because of an inability to strategize and fully comprehend the consequences of their decisions.

Researchers have attempted to measure risk propensity as a single personality trait, but propensity to engage in risk is dependent both on characteristics of the individual and the situation. A dual process theory of decision making seems to describe how three main factors influence risky decision making (RDM). Individuals can have a predisposition for higher valuation in one of the processes, the characteristics of the situation can predispose an individual towards one process over another, and individuals can be differentially affected by the situational differences. I proposed a model that utilizes impulsivity as a measure of individual process predisposition, gambles that differed between frames as losses or gains, and the HEXACO personality traits to predict RDM. 158 participants (M = 19.0 years, SD = 1.04) performed 20 decision-making tasks, 10 framed in terms of losses and 10 framed in terms of gains, and then responded to personality measures. Participants made more risky decisions in the loss frame than in the gain frame. Lack of follow through and conscientiousness were negatively associated with RDM, both being possible measures of process predisposition. The HEXACO personality traits did not moderate the framing effect suggesting interpretation of frames were not dependent upon the HEXACO traits. Future research should be focused on the differences between the five-factor model and the HEXACO model in decision tasks and should further evaluate the dual process theory to better inform future research on decision making.

Here is a book that challenges the very basis of the way psychologists have studied child development. According to Urie Bronfenbrenner, one of the world's foremost developmental psychologists, laboratory studies of the child's behavior sacrifice too much in order to gain experimental control and analytic rigor. Laboratory observations, he argues, too often lead to "the science of the strange behavior of children in strange situations with strange adults for the briefest possible periods of time." To understand the way children actually develop, Bronfenbrenner believes that it will be necessary to observe their behavior in natural settings, while they are interacting with familiar adults over prolonged periods of time. This book offers an important blueprint for constructing such a new and ecologically valid psychology of development. The blueprint includes a complete conceptual framework for analysing the layers of the environment that have a formative influence on the child. This framework is applied to a variety of settings in which children commonly develop, ranging from the pediatric ward to daycare, school, and various family configurations. The result is a rich set of hypotheses about the developmental consequences of various types of environments. Where current research bears on these hypotheses, Bronfenbrenner marshals the data to show how an ecological theory can be tested. Where no relevant data exist, he suggests new and interesting ecological experiments that might be undertaken to resolve current unknowns. Bronfenbrenner's groundbreaking program for reform in developmental psychology is certain to be controversial. His argument flies in the face of standard psychological procedures and challenges psychology to become more relevant to the ways in which children actually develop. It is a challenge psychology can ill-afford to ignore.

In the current study, I examined the effects of age, explicitness of instructional materials, and personality differences on risky decision making while playing the Game of Dice Task (GDT). Participants were randomly assigned to one of two instruction conditions: Explicit vs. Standard. In the explicit condition, the instructions were very straightforward, with respect to risk, while the instructions in the standard condition were not. To describe this game in more detail, in the GDT, participants decide how risky they wish to be on each trial. To optimize performance, participants should make "safe" rather than risky choices. Overall, older adults were riskier than younger adults on the GDT even though they self-report being more risk averse than younger adults in several different risk domains except for social. In regards to the instruction condition, there were no significant age differences in the standard condition. Younger and older adults perform similarly. However, there were age differences in the explicit condition. Older adults were riskier in the explicit condition than younger adults were. In addition, a 3-way interaction between age, instruction, and conscientiousness was discovered. Older adults who are low in conscientiousness perform similar to regular older adults in the standard and explicit conditions. However, the effect of instruction condition disappears for those who are high in conscientiousness.
