Smarter than we think: when our brains detect that we are biased

Human reasoning is often biased by stereotypical intuitions. The nature of such bias is not clear. Some authors claim that people are mere heuristic thinkers and are not aware that cued stereotypes might be inappropriate. Other authors claim that people always detect the conflict between their stereotypical thinking and normative reasoning, but simply fail to inhibit stereotypical thinking. Hence, it is unclear whether heuristic bias should be attributed to a lack of conflict detection or a failure of inhibition. We introduce a neuroscientific approach that bears on this issue. Participants answered a classic decision-making problem (the "lawyer-engineer" problem) while the activation of brain regions believed to be involved in conflict detection (anterior cingulate) and response inhibition (lateral prefrontal cortex) was monitored. Results showed that although the inhibition area was specifically activated when stereotypical responses were avoided, the conflict-detection area was activated even when people reasoned stereotypically. The findings suggest that people detect their bias when they give intuitive responses.

The effects of revisionism on remembered emotion: the valence of older,voluntary immigrants' pre‐migration autobiographical memories

Prior research on remembered emotion demonstrates effects of revisionism in memory. The positivity bias describes preferential recall for positive emotions and the fading affect bias describes greater fading of negative versus positive emotion over time. Such effects predict that older adults would remember childhood and youth more positively than later adulthood. However, economic immigrants, whose childhood and youth reflect experiences of poverty and unemployment, may not show the effects of such revisionism. This study examined the remembered emotion of immigrant and non‐immigrant older Puerto Ricans whose early years corresponded to hard times on the island. Multilevel modelling showed that both groups exhibited the effects of the positivity and fading affect biases, but immigrants remembered childhood and youth more negatively than non‐immigrants. This suggests both accurate memory for a more negative past as well the effects of additional revisionism whereby a valued and chosen present is preferentially compared to the past.

VR-based conversation training program for patients with schizophrenia: a preliminary clinical trial.

Schizophrenia is a devastating mental illness and is characterized by hallucinations and delusions as well as social skills deficits. Generally, social skills training designed to help patients develop social skills includes role-playing, but this form of training has typical shortcomings, which are largely due to a trainer's difficulties to project emotion. Virtual reality (VR)-based techniques have the potential to solve these difficulties, because they provide a computer-generated but realistic three-dimensional world and humanlike avatars that can provide emotional stimuli. In this paper, we report on a method of implementing virtual environments (VEs) in order to train people with schizophrenia to develop conversational skills in specific situations, which could overcome the shortcomings of or complement conventional role-playing techniques. The paper reports the efficacy of the proposed approach in a preliminary clinical trial with 10 patients with schizophrenia.     

Demand characteristics and self-report measures of imaginary audience sensitivity: implications for interpreting age differences in adolescent egocentrism.

Self-consciousness during early adolescence has been explained as an outcome of adolescent egocentrism, in which adolescents create an imaginary audience (IA) of attentive, critical peers. The possibility that such self-consciousness might result from contact with peers who are more attentive and critical than those encountered during childhood or adulthood has not been considered. Study 1 tested whether young adults, who are not theoretically susceptible to IA, could be made to receive high scores on IA and self-consciousness measures by having them complete a procedure in 1 of 3 laboratory conditions-a critical audience, a noncritical audience, or no audience. However, participants in the critical-audience condition received significantly lower IA and self-consciousness scores than participants in the no-audience condition did. Study 2 tested whether the directions given to Study 1 participants might have been responsible for the unexpected findings. Results indicated that participants instructed to give mature-sounding responses received lower IA/self-consciousness scores than did those asked to report their honest opinions. Together, the results of Studies 1 and 2 indicated that survey measures of IA are subject to demand characteristics and highlighted the need to interpret with caution age differences in IA as traditionally assessed.     

Selective responsiveness of chronically ill children to assessments of depression.

Many investigators have noted that depression is a common symptom among pediatric cancer patients. However, prevalence rates vary widely across studies. This variation in prevalence rates may be due, in part, to selective reporting of patients based on measures used and environmental cues. In this study, we evaluated 50 chronically ill pediatric patients (19 cancer and 31 diabetic patients) for their use of selective reporting of depression. Factors in the 2 x 2 design were Intervention (disclosure videotape and cartoon videotape) and Examiner (familiar examiner and unfamiliar examiner). In the Intervention manipulation, subjects were shown either a videotape prompting the child that self-disclosure was appropriate or a tape of a cartoon (control condition). In the Examiner manipulation, subjects were administered the experimental measures by either a familiar (parent) or unfamiliar (research assistant) examiner. Dependent variables were the Children's Depression Inventory (CDI; Kovacs, 1981), the Depression scale of the Roberts Apperception Test for Children (RATC; McArthur & Roberts, 1982), and a depression measure taken from the Child Behavior Checklist (CBCL; Achenbach & Edelbrock, 1983). As hypothesized, the Examiner x Intervention interaction revealed that children who did not view the disclosure videotape and who were tested by an unfamiliar examiner gave significantly lower self-reports of depression on the CDI than children in the other conditions. However, parent and child projective reports of depression did not vary as a function of experimental condition. The results are interpreted as selective responding on the part of pediatric patients. Limitations of assessing internal psychological states in children are discussed.     

Newborn screening for cystic fibrosis: Educational implications

We examined the educational implications of newborn screening for cystic fibrosis (CF) as performed by combining the measurement of immunoreactive trypsin with analysis for the most common CF mutation, F508. Four out of 77 (5%) of maternity staff from 11 hospitals in rural New South Wales, Australia had learned about the salient features of the screening protocol from a pamphlet distributed from a central laboratory. In comparison, a didactic lesson resulted in a significantly greater (p<0.00006) number of maternity staff learning about the salient features of the screening protocol. Most maternity staff expanded their explanation to parents of newborn babies because of the didactic lesson.     

Microcomputers in psychology laboratory courses

The implementation of a microcomputer-based laboratory curriculum is described and analyzed in terms of general guidelines for introducing computer-based instruction. Procedures are suggested for analyzing need, choosing a system, and implementing the project. Pedagogical considerations arising from the use of computer technology are also discussed.     

The Effect of Internal Locus of Control on Career Adaptability: The Mediating Role of Career Decision‐Making Self‐Efficacy and Occupational Engagement

This study examined the mediating roles of career decision‐making self‐efficacy (a domain‐specific motivational variable) and occupational engagement (a behavioral variable) on the relationship between internal locus of control (a general motivational variable) and career adaptability among college students in South Korea (N = 310). The findings extend past research on career adaptability by identifying a relationship among the variables.     

The Power to Detect and Predict Individual Differences in Intra-Individual Variability Using the Mixed-Effects Location-Scale Model

Our goal is to provide empirical scientists with practical tools and advice with which to test hypotheses related to individual differences in intra-individual variability using the mixed-effects location-scale model. To that end, we evaluate Type I error rates and power to detect and predict individual differences in intra-individual variability using this model and provide empirically-based guidelines for building scale models that include random and/or systematically-varying fixed effects. We also provide two power simulation programs that allow researchers to conduct a priori empirical power analyses. Our results aligned with statistical power theory, in that, greater power was observed for designs with more individuals, more repeated occasions, greater proportions of variance available to be explained, and larger effect sizes. In addition, our results indicated that Type I error rates were acceptable in situations when individual differences in intra-individual variability were not initially detectable as well as when the scale-model individual-level predictor explained all initially detectable individual differences in intra-individual variability. We conclude our paper by providing study design and model building advice for those interested in using the mixed-effects location-scale model in practice.
