Going with your gut: How William James' theory of emotions brings insights to risk perception and decision making research

The basic premise of William James' theory of emotions – that bodily changes lead to emotional feelings – ignited debate about the relative importance of bodily processes and cognitive appraisals in determining emotions. Similarly, theories of risk perception have been expanding to include emotional and physiological processes along with cognitive processes. Taking a closer look at The Principles of Psychology, this article examines how James' propositions support and extend current research on risk perception and decision making. Specifically, James (1) described emotional feelings and their related cognitions in ways similar to current dual processing models; (2) defended the proposition that emotions and their expressions serve useful and adaptive functions; (3) suggested that anticipating an emotion can trigger that emotion due to associations learned from past experiences; and (4) highlighted individual differences in emotional experiences that map on well with individual differences in risk-related decision making.

Evidence for an emotion-cognition interaction in the statistical prediction of suicide attempts

Suicidal behavior is a prevalent problem among adolescents and young adults. Although most theoretical models of suicide suggest that this behavior results from the interaction of different risk factors, most prior studies have tested only bivariate associations between individual risk factors and suicidal behaviors. The current study was designed to address this limitation by testing the effect of an emotion–cognition interaction on suicide attempts among youth. Specifically, we hypothesized that the interaction of emotion reactivity and problem-solving skills would statistically predict the probability of a recent suicide attempt among 87 adolescents and young adults. Results revealed a significant interaction, such that emotion reactivity was strongly associated with the probability of a suicide attempt among those with poor problem-solving skills, moderately associated among those with average problem-solving skills, and not significantly associated among those with good problem-solving skills. The next generation of studies on suicidal behavior should continue to examine how risk factors interact to predict this dangerous outcome.     

"I had so much it didn't seem fair": Eight-year-olds reject two forms of inequity

Research using economic games has demonstrated that adults are willing to sacrifice rewards in order to prevent inequity both when they receive less than a social partner (disadvantageous inequity) and when they receive more (advantageous inequity). We investigated the development of both forms of inequity aversion in 4- to 8-year-olds using a novel economic game in which children could accept or reject unequal allocations of candy with an unfamiliar peer. The results showed that 4- to 7-year-olds rejected disadvantageous offers, but accepted advantageous offers. By contrast, 8-year-olds rejected both forms of inequity. These results suggest that two distinct mechanisms underlie the development of the two forms of inequity aversion.     

Changes in children’s perception-action tuning over short time scales: Bicycling across traffic-filled intersections in a virtual environment

This investigation examined short-term changes in child and adult cyclists’ gap decisions and movement timing in response to general and specific road-crossing experiences. Children (10- and 12-year-olds) and adults rode a bicycle through a virtual environment with 12 intersections. Participants faced continuous cross traffic and waited for gaps they judged were adequate for crossing. In the control condition, participants encountered randomly ordered gaps ranging from 1.5 to 5.0 s at all intersections. In the high-density condition, participants encountered high-density intersections sandwiched between sets of control intersections. These high-density intersections were designed to push participants toward taking tighter gaps. Participants in both conditions were more likely to accept 3.5-, 4.0-, 4.5-, and 5.0-s gaps at the last set of intersections than at the first set of intersections, whereas participants in the high-density condition were also more likely to accept very tight 3.0-s gaps at the last intersections than at the first intersections. Moreover, individuals in the high-density condition who waited less and took shorter gaps at the middle intersections were also more likely to take very tight 3.0-s gaps at the last intersections. The 10-year-olds in both conditions had more time to spare when they cleared the path of the oncoming car at the last intersections, whereas the 12-year-olds and adults showed no change in time to spare across intersections. The discussion focuses on linking short-term change in perceptual-motor functioning to longer term perceptual-motor development.     

Demographic and familial predictors of early executive function development: Contribution of a person-centered perspective

Executive function (EF) skills are integral components of young children’s growing competence, but little is known about the role of early family context and experiences in their development. We examined how demographic and familial risks during infancy predicted EF competence at 36 months of age in a large, predominantly low-income sample of nonurban families from Pennsylvania and North Carolina in the United States. Using latent class analysis, six ecological risk profiles best captured the diverse experiences of these families. Profiles with various combinations of family structure, income, and psychosocial risks were differentially related to EF. Much of the influence of early risks on later EF appears to be transmitted through quality of parent-child interactions during infancy. Findings suggest that early family environments may prove to be especially fruitful contexts for the promotion of EF development.     

The vigilant parent: Parental role salience affects parents' risk perceptions, risk-aversion, and trust in strangers

Since parenting involves protecting children from various risks and dangers, tendencies towards increased risk perception, risk-averse decision-making, and distrust of strangers may come to be associated with the parental role. Consequently, parents may be more likely to exhibit each of these psychological tendencies when their parental role is situationally salient than when it is not salient. We tested this hypothesis in two studies that manipulated the salience of the parental role in samples of parents and nonparents and measured the effects on participants' risk perceptions, risk-aversion, and trust in strangers. As we hypothesized, parents perceived greater risk (Study 1), made more risk averse choices (Study 1), and trusted strangers less (Study 2) when their parental role was salient than when it was not salient. Implications for understanding psychological adaptations to social roles are discussed.     

Cognitive model decomposition of the BART: Assessment and application

The Balloon Analogue Risk Task, or BART, aims to measure risk taking behavior in a controlled setting. In order to quantify the processes that underlie performance on the BART, Wallsten, Pleskac, and Lejuez (2005) proposed a series of mathematical models whose parameters have a clear psychological interpretation. Here we examine a 2-parameter simplification of Wallsten et al.’s preferred 4-parameter model. A parameter recovery study shows that — with plausible restrictions on the number of participants and trials — both parameters (i.e., risk taking γ⁺ and response consistency β) can be estimated accurately. To demonstrate how the 2-parameter model can be used in practice, we implemented a Bayesian hierarchical version and applied it to an empirical data set in which participants performed the BART following various amounts of alcohol intake.     

The utility and accuracy of oral reading fluency score types in predicting reading comprehension

This study used data from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2002) oral reading fluency (ORF) probes to examine variation among different ORF score types (i.e., the median of three passages, the mean of all three passages, the mean of passages 2 and 3, and the score from passage 3) in predicting reading comprehension as a function of student reading fluency level and to compare the screening accuracy of these score types in predicting student reading comprehension. The results revealed that the relation between oral reading fluency and reading comprehension varied as a function of students' oral reading fluency and that different score types had varying predictive validity for year-end reading comprehension. The mean of all three passages demonstrated a marginally better balance in screening efficiency from September to December of grade one (especially for low-performing students), whereas in grades two and three, the median score was the best predictor. Furthermore, across all grades, increasing reading rates were observed for the three administered passages within an assessment period. The observed patterns mimicked previous experimental studies (Francis et al., 2008; Jenkins, Graff, & Miglioretti, 2009), suggesting that practice effects are an important consideration in the administration of multiple passages assessing oral reading fluency.     

Relationships between digit ratio 2D:4D and self-reported aggression and risk taking in an online study

2D:4D, the length ratio of the second to the fourth digit, is a putative measure of prenatal testosterone, which may have effects on aggression and risk taking. Participants in a German online study (>1000 females, >1200 males) submitted their self-measured digit lengths and self-report measures on verbal and physical aggression and risk taking. For males, left-hand 2D:4D and verbal aggression correlated significantly (r = −.10, after correction for age and reduced reliability in self-measured 2D:4D), with other relationships being similar but non-significant. For females, no relationships between aggression and 2D:4D were found. Risk taking and right-hand 2D:4D correlated significantly in women (r = −.10, after correction for age and reduced reliability in self-measured 2D:4D); similar, but statistically non-significant, relationships were found in men. The result corroborates an emerging view that 2D:4D is negatively related to aggression in males and that 2D:4D is negatively related to risk taking. This tentatively points to effects of prenatal testosterone on these characteristics.
