Chimpanzees (Pan troglodytes) can wait,when they choose to: a study with the hybrid delay task

Self-control has been studied in nonhuman animals using a variety of tasks. The inter-temporal choice (ITC) task presents choices between smaller–sooner (SS) and larger–later (LL) options. Using food amounts as rewards, this presents two problems: (a) choices of the LL option could either reflect self-control or instead result from animals’ difficulty with pointing to smaller amounts of food; (b) there is no way to verify whether the subjects would not revert their choice for the LL option, if given the opportunity to do so during the ensuing delay. To address these problems, we have recently introduced a new protocol, the hybrid delay task, which combines an initial ITC with a subsequent accumulation phase in which selection of the SS option leads to its immediate delivery, but choice of the LL option then leads to one-by-one presentation of those items that continues only as long as the subject does not eat any of the accumulated items. The choice of the LL option therefore only reflects self-control when the number of items obtained from LL choices during the accumulation phase is higher than what could be received in the SS option. Previous research with capuchin monkeys demonstrated that their apparent self-control responses in the ITC task may have overestimated their general self-control abilities, given their poor performance in the hybrid delay task. Here, chimpanzees instead demonstrated that their choices for the LL option in the ITC phase of the hybrid delay task were confirmed by their ability to sustain long delays during accumulation of LL rewards.     

The Art Therapy Practice Research Network: Hurdles,pitfalls and achievements

Aim: This article gives an overview of the setting up of the Art Therapy Practice Research Network (ATPRN) in 2000, amidst a culture resistant to research. The authors discuss their experiences in changing this culture and encouraging art therapists to become practitioner/researchers. They identify learning points that may be helpful for other professionals who want to form new practice research networks (PRNs). Context: The research and practice context contemporary to the ATPRN foundation is outlined and identified as a significant influence on its inception and development. Key events in the 14 years of the PRN's life and articles on art therapy and psychotherapy research published at the time of the ATPRN foundation are used to illuminate the historical context. ATPRN newsletters and symposium reports were consulted to identify themes and issues across 14 years of development and growth. Learning points: Several learning points are identified and listed as useful factors to address when setting up and maintaining a PRN and include: shape the culture from the start; review and revise; get practical together; encourage members' presentations; build synergy with professional body; embed the ATPRN around all aspects of research publication. Conclusions: Successful PRNs depend on making practitioners feel included from the start by acknowledging fear and anxiety about research. Providing practical projects helped practitioners to feel less isolated by being part of a meaningful and productive network. Maintaining and developing PRNs is an iterative process that demands constant reviewing and revising.     

Shared Decision-Making Among Caregivers and Health Care Providers of Youth with Type 1 Diabetes

The present study aimed to examine perceptions of shared decision-making (SDM) in caregivers of youth with type 1 diabetes (T1D). Interview, survey data, and HbA1c assays were gathered from caregivers of 439 youth with T1D aged 3–18 years. Caregiver-report indicated high perceived SDM during medical visits. Multivariable linear regression indicated that greater SDM is associated with lower HbA1c, older child age, and having a pediatric endocrinologist provider. Multiple logistic regression found that caregivers who did not perceive having made any healthcare decisions in the past year were more likely to identify a non-pediatric endocrinologist provider and to report less optimal diabetes self-care. Findings suggest that youth whose caregivers report greater SDM may show benefits in terms of self-care and glycemic control. Future research should examine the role of youth in SDM and how best to identify youth and families with low SDM in order to improve care.     

Using the Tenets of the Problem‐Centered Systems Therapy of the Family (PCSTF) to Teach the McMaster Approach to Family Therapists

This article describes the videoconferencing training of a group of family therapists in the McMaster Approach to evaluating and treating families. A discussion of the key tenets of the McMaster Approach lays the groundwork for how these tenets were applied to training in a residential treatment agency for adolescents. The article serves as an example of how videoconference technology can facilitate extended training, even from a distance.     

Religion and Political Decision Making

Influential political theorists suggest that religious differences in political life may be overcome through shared commitment to political processes. In this article, I subject the underlying assumptions of this proposition to empirical inquiry. When faced with substantive conflict over policy outcomes, do religious persons defer to a political process for resolution? And if so, to which political process do they defer? Through a novel interview exercise with 61 respondents from a variety of religious backgrounds, I find a general willingness to defer to a legitimate political process, even if it results in an undesirable outcome that violates religious (or other) political preferences. However, I also find that a political process need not be democratic to be seen as legitimate, and that process preferences do not map onto religious differences.     

The Relationship Between Sluggish Cognitive Tempo and Impairment in Children With and Without ADHD

This study examined impairment in multiple domains of functioning in children with and without ADHD who present with high or low levels of sluggish cognitive tempo (SCT) while taking into account the total symptom ratings of ADHD. Participants were 584 children in kindergarten through eighth grade (55.7 % male, 91.7 % Caucasian), drawn from five archival datasets. Two, 2 (SCT groups: high and low) x 3 (ADHD Status: ADHD-I, ADHD-C, and non-ADHD) MANCOVAs were conducted with the total ADHD symptom ratings and child age as covariates. One MANCOVA was conducted on scores on the teacher Impairment Rating Scale (IRS; Fabiano et al. Journal of Clinical Child and Adolescent Psychology 35:369–385, 2006) and the other on the 6 scores on the parent IRS. The results indicated that the presence of SCT symptoms was associated with greater functional impairment at home according to parent report while it was associated with less functional impairment at school according to teacher report. Thus, the relationship between SCT symptoms and impairment differs depending on the informant and the context in which impairment is evaluated.     

Neighborhood Racial Composition,Racial Discrimination,and Depressive Symptoms in African Americans

While evidence indicates that experienced racial discrimination is associated with increased depressive symptoms for African Americans, there is little research investigating predictors of experienced racial discrimination. This paper examines neighborhood racial composition and sociodemographic factors as antecedents to experienced racial discrimination and resultant levels of depressive symptoms among African American adults. The sample included 505 socioeconomically-diverse African American adults from Baltimore, MD. Study data were obtained via self-report and geocoding of participant addresses based on 2010 census data. Study hypotheses were tested using multiple pathways within a longitudinal Structural Equation Model. Experienced racial discrimination was positively associated with age and sex such that older individuals and males experienced increased levels of racial discrimination. In addition, the percentage of White individuals residing in a neighborhood was positively associated with levels of experienced racial discrimination for African American neighborhood residents. Experienced racial discrimination was positively associated with later depressive symptoms. Neighborhood-level contextual factors such as neighborhood racial composition and individual differences in sociodemographic characteristics appear to play an important role in the experience of racial discrimination and the etiology of depression in African American adults.     

The impact of salesperson credibility-building statements on later stages of the sales encounter

Salespeople frequently attempt to build credibility on their first encounter with a customer. Because customers actively evaluate persuasive messages, it is important to understand their reactions to credibility-building tactics and how these reactions shape the sales interaction. Accordingly, this study investigates customers' reactions to two types of credibility-building statements – benevolence and expertise – using a multistep qualitative analysis of sales transactions in the life insurance industry, along with surveys before and after the sales encounter. Empirical results show that customers are more likely to react positively to credibility-building statements that match their buying style expectations. Furthermore, when customers react positively to a credibility-building tactic, salespeople are more likely to continue using that tactic when addressing customer objections. However, whereas benevolence tactics for addressing customer objections lead to stronger relational outcomes, the findings indicate that expertise tactics do not. Thus, matching sales tactics with customers' buying style expectations is beneficial in the early stages of the sales encounter, but customer objections are best addressed with benevolence tactics, regardless of customers' buying style.     

Debiasing by instruction: The case of belief bias

Abstract

The study is concerned with the question of whether robust biases in reasoning can be reduced or eliminated by verbal instruction in principles of reasoning. Three experiments are reported in which the effect of instructions upon the belief bias effect in syllogistic reasoning is investigated. Belief bias is most clearly marked by a tendency for subjects to accept invalid conclusions which are a priori believable. Experiment 1 attempted to replicate and extend an experiment reported by Newstead, Pollard, Evans and Allen (1992). In contrast with their experiment, it was found that belief bias was maintained despite the use of augmented instructions which emphasised the principle of logical necessity. Experiment 2 provided an exact replication of the augmented instructions condition of Newstead et al., including the presence of problems with belief-neutral conclusions. Once again, significant effects of conclusion believability were found. A third experiment examined the use of elaborated instructions which lacked specific reference to the notion of logical necessity. The use of these instructions significantly reduced the effects of belief on the reasoning observed.

Taking the current findings together with the experiment of Newstead et al., the overall conclusion is that elaborated instructions can reduce the belief bias effect in syllogistic reasoning, but not eliminate it. This conclusion is discussed with reference to (1) the practical implications for improving thinking and reasoning via verbal instruction and (2) the nature of the belief bias phenomenon.     

Unrecognized Changes in the Self Contribute to Exaggerated Judgments of External Decline

People commonly perceive social conditions as declining. We propose that perceptions of social decline are often a consequence of a bias whereby people mistake change in themselves for change in the world. The present research demonstrates that common personal changes such as the parenthood transition (Studies 1–2) and physical aging (Study 3) may increase a person's sensitivity to dangers and thereby contribute to an illusory perception that external dangers are increasing. We use experimental models of the hypothesized change processes to test whether these common personal changes may contribute to judgments of social decline.
