The influence of improper sets of information on judgment: how irrelevant information can bias judged probability

This article introduces 2 new sources of bias in probability judgment, discrimination failure and inhibition failure, which are conceptualized as arising from an interaction between error prone memory processes and a support theory like comparison process. Both sources of bias stem from the influence of irrelevant information on participants' probability judgments, but they postulate different mechanisms for how irrelevant information affects judgment. The authors used an adaptation of the proactive interference (PI) and release from PI paradigm to test the effect of irrelevant information on judgment. The results of 2 experiments support the discrimination failure account of the effect of PI on probability judgment. In addition, the authors show that 2 commonly used measures of judgment accuracy, absolute and relative accuracy, can be dissociated. The results have broad implications for theories of judgment.     

Giving the boot to the bootstrap: how not to learn the natural numbers

According to one theory about how children learn the concept of natural numbers, they first determine that "one", "two", and "three" denote the size of sets containing the relevant number of items. They then make the following inductive inference (the Bootstrap): The next number word in the counting series denotes the size of the sets you get by adding one more object to the sets denoted by the previous number word. For example, if "three" refers to the size of sets containing three items, then "four" (the next word after "three") must refer to the size of sets containing three plus one items. We argue, however, that the Bootstrap cannot pick out the natural number sequence from other nonequivalent sequences and thus cannot convey to children the concept of the natural numbers. This is not just a result of the usual difficulties with induction but is specific to the Bootstrap. In order to work properly, the Bootstrap must somehow restrict the concept of "next number" in a way that conforms to the structure of the natural numbers. But with these restrictions, the Bootstrap is unnecessary.     

Risk perception and conspiracy theory endorsement predict compliance with COVID-19 public health measures

Public health measures such as spatial distancing and physical hygiene have been found effective in mitigating the spread of the coronavirus. However, there is considerable variability in individual compliance with such public health measures and factors contributing to these interindividual differences are currently still understudied. The present study set out to determine the role of risk perception and conspiracy theory endorsement on compliance with COVID-19 public health measures and explored variations in these associations across participant age and the developmental status of a country, leveraging a large multi-national data set (N = 45,772) across 66 countries/territories, collected via online survey during the early phase of the COVID-19 pandemic (between April and May 2020). Human Development Index (HDI), developed by the United Nations Development Program, was used as a proxy of a country's achievement in key dimensions of human development. Overall, higher risk perception was associated with greater compliance, particularly in individuals with greater conspiracy theory endorsement. Specifically, people from more developed countries who perceived themselves less at risk but showed stronger conspiracy theory endorsement reported the lowest compliance with COVID-19 public health measures. Findings from this study advance understanding of the interplay between risk perception and conspiracy theory endorsement in their effect on compliance with COVID-19 public health measures, under consideration of both individual-level and country-level demographic variables and have potential to inform the design of tailored interventions to fight the current and future global pandemics.     

Redemptive processing of impactful COVID-19 experiences predicts well-being among older but not younger adults

People engage in autobiographical reasoning to make sense of major life events. This study examined whether younger and older adults utilized different autobiographical reasoning strategies to make sense of highly emotional and impactful experiences during the COVID-19 pandemic. We hypothesized that older adults would show higher levels of redemptive processing, younger adults would show higher levels of exploratory processing, and that these respective processes would be associated with well-being for each group. Two samples of younger (n = 245; ages 17–22) and older (n = 224; ages 55–83) adults provided written narratives about their most impactful positive and negative experiences from the COVID-19 pandemic and responded to a questionnaire assessing well-being. We found that younger and older adults did not differ in their use of exploratory and redemptive processing. Redemptive processing was uniquely predictive of well-being among older adults, although this relationship disappeared when positive and negative events were considered independently. These results suggest that the ability to positively reframe COVID-related events could be particularly important for the well-being of older adults.     

Teaching children with autism to engage in peer-directed mands using a picture exchange communication system

We evaluated differential reinforcement of alternative behavior (DRA) plus prompting to increase peer-directed mands for preferred items using a picture exchange communication system (PECS). Two nonvocal individuals with autism participated. Independent mands with a peer increased with the implementation of DRA plus prompting for both participants. In addition, peers engaged in brief social interactions following the majority of mands for leisure items. These results suggest that teaching children to use PECS with peers may be one way to increase manding and social interactions in individuals with limited or no vocal repertoire.     

Feeling threatened about the future: Whites' emotional reactions to anticipated ethnic demographic changes

In many Western countries, the proportion of the population that is White will drop below 50% within the next century. Two experiments examined how anticipation of these future ethnic demographics affects current intergroup processes. In Study 1, White Americans who viewed actual demographic projections for a time when Whites are no longer a numerical majority felt more angry toward and fearful of ethnic minorities than Whites who did not view future projections. Whites who viewed the future projections also felt more sympathy for their ingroup than Whites in the control condition. In Study 2, the authors replicated the effects for intergroup emotions with a sample of White Canadians. White Canadians who thought about a future in which Whites were a numerical minority appraised the ingroup as more threatened, which mediated the effect of condition on intergroup emotions. The authors discuss the implications of these findings for race relations in increasingly diverse societies.     

Integrating Religion and Spirituality Into Treatment for Late-Life Anxiety: Three Case Studies

Generalized anxiety disorder (GAD) is common in older adults and, although cognitive behavioral therapy (CBT) is an efficacious treatment for late-life GAD, effect sizes are only moderate and attrition rates are high. One way to increase treatment acceptability and enhance current cognitive behavioral treatments for GAD in older adults might be to incorporate religion/spirituality (R/S). The cases presented here illustrate the use of a 12-week modular CBT intervention for late-life anxiety, designed to allow incorporation of R/S elements in accordance with patient preferences. The three women treated using this protocol chose different levels and methods of R/S integration into therapy. All three women showed substantial improvement in worry symptoms, as well as a variety of secondary outcomes following treatment; these gains were maintained at 6-month follow-up. These preliminary results suggest that the incorporation of R/S into CBT might be beneficial for older adults with GAD. Strengths, limitations, and future directions are discussed.     

Sport psychology group consultation using social networking web sites

A social networking Web site, Facebook, was used to deliver long-term sport psychology consultation services to student-athletes (i.e., soccer players) in 30- to 60-min weekly sessions. Additional short-term team building, group cohesion, communication, anger management, injury rehabilitation, mental toughness, commitment, and leadership workshops were provided. Cohesion and overall relationships between both the student-athletes and the sport psychology consultants benefited from this process. Social networking Web sites offer a practical way of providing sport psychology consulting services that does not require use of major resources.

Evaluator agreement in placement recommendations for insanity acquittees

Research has examined differences between psychologists and psychiatrists in opinions on trial competency and criminal responsibility, but there is little research on such differences in risk assessment. This study examined the impact of disciplinary affiliation on opinions regarding whether new insanity acquittees should be hospitalized or released, and the risk factors given the most weight by each discipline. There was no significant difference between disciplines in the frequency of recommendations for hospitalization versus release. However, the concordance rate at the individual case level was only moderate when controlling for chance, which raises questions about the reliability and validity of forensic risk assessments in real-world settings. A number of variables emerged as significant in the decision-making of each discipline, with some differences noted.
