Infinite Epistemic Regresses and Internalism

This article seeks to state, first, what traditionally has been assumed must be the case in order for an infinite epistemic regress to arise. It identifies three assumptions. Next it discusses Jeanne Peijnenburg's and David Atkinson's setting up of their argument for the claim that some infinite epistemic regresses can actually be completed and hence that, in addition to foundationalism, coherentism, and infinitism, there is yet another solution (if only a partial one) to the traditional epistemic regress problem. The article argues that Peijnenburg and Atkinson fail to address the traditional regress problem, as they don't adopt all of the three assumptions that underlie the traditional regress problem. It also points to a problem in the notion of making probable that Peijnenburg and Atkinson use in their account of justification.     

Beyond commitment: entrenchment in the buyer–seller exchange

A specific empirical finding in the buyer–seller literature – initially discovered by Moorman, Zaltman, and Deshpande and subsequently replicated by Grayson and Ambler – still suffers from incomplete explanation. In business-to-business marketing, why do some long-term buyers appear to trust their providers a great deal but not use the service provided? This research endeavours to more fully explain this ‘dark side’ of relationship selling by integrating work on the economic theory of entrenchment with Dwyer, Schurr, and Oh's seminal buyer–seller framework. The result is a modified conceptual model of the buyer–seller exchange in which potential seller entrenchment follows Dwyer et al.'s courting and commitment stages. Motivated by Dwyer et al.'s urging to examine their model using a negotiation lens, this research then borrows two contrasting orientations from the negotiation literature and offers propositions regarding how buyers and sellers interact at each stage of the exchange. In addition to enriching understanding of how buyers and sellers negotiate in the courting and commitment stages, this research is the first to offer insight into how both sides might negotiate when faced with seller entrenchment.     

Cognitive performance in older adults with stable heart failure: Longitudinal evidence for stability and improvement

Cognitive impairment is prevalent in heart failure (HF), though substantial variability in the pattern of cognitive impairment is found across studies. To clarify the nature of cognitive impairment in HF, we examined longitudinal trajectories across multiple domains of cognition in HF patients using latent growth class modeling. 115 HF patients completed a neuropsychological battery at baseline, 3-months and 12-months. Participants also completed the Beck Depression Inventory-II (BDI-II). Latent class growth analyses revealed a three-class model for attention/executive function, four-class model for memory, and a three-class model for language. The slope for attention/executive function and language remained stable, while improvements were noted in memory performance. Education and BDI-II significantly predicted the intercept for attention/executive function and language abilities. The BDI-II also predicted baseline memory. The current findings suggest that multiple performance-based classes of neuropsychological test performance exist within cognitive domains, though case-controlled prospective studies with extended follow-ups are needed to fully elucidate changes and predictors of cognitive function in HF.     

AMAB: Automated measurement and analysis of body motion

Technologies that measure human nonverbal behavior have existed for some time, and their use in the analysis of social behavior has become more popular following the development of sensor technologies that record full-body movement. However, a standardized methodology to efficiently represent and analyze full-body motion is absent. In this article, we present automated measurement and analysis of body motion (AMAB), a methodology for examining individual and interpersonal nonverbal behavior from the output of full-body motion tracking systems. We address the recording, screening, and normalization of the data, providing methods for standardizing the data across recording condition and across subject body sizes. We then propose a series of dependent measures to operationalize common research questions in psychological research. We present practical examples from several application areas to demonstrate the efficacy of our proposed method for full-body measurements and comparisons across time, space, body parts, and subjects.     

“Plateau”-related summary statistics are uninformative for comparing working memory models

Performance on visual working memory tasks decreases as more items need to be remembered. Over the past decade, a debate has unfolded between proponents of slot models and slotless models of this phenomenon (Ma, Husain, Bays (Nature Neuroscience 17, 347-356, 2014). Zhang and Luck (Nature 453, (7192), 233-235, 2008) and Anderson, Vogel, and Awh (Attention, Perception, Psychophys 74, (5), 891-910, 2011) noticed that as more items need to be remembered, “memory noise” seems to first increase and then reach a “stable plateau.” They argued that three summary statistics characterizing this plateau are consistent with slot models, but not with slotless models. Here, we assess the validity of their methods. We generated synthetic data both from a leading slot model and from a recent slotless model and quantified model evidence using log Bayes factors. We found that the summary statistics provided at most 0.15 % of the expected model evidence in the raw data. In a model recovery analysis, a total of more than a million trials were required to achieve 99 % correct recovery when models were compared on the basis of summary statistics, whereas fewer than 1,000 trials were sufficient when raw data were used. Therefore, at realistic numbers of trials, plateau-related summary statistics are highly unreliable for model comparison. Applying the same analyses to subject data from Anderson et al. (Attention, Perception, Psychophys 74, (5), 891-910, 2011), we found that the evidence in the summary statistics was at most 0.12 % of the evidence in the raw data and far too weak to warrant any conclusions. The evidence in the raw data, in fact, strongly favored the slotless model. These findings call into question claims about working memory that are based on summary statistics.     

Health Related Quality of Life and Social Support in Pediatric Patients with Pacemakers

Prior research evaluating health-related quality of life (HRQOL) among pediatric patients with internal cardiac devices has primarily focused on children with cardiac defibrillators, with scant attention devoted to pacemaker recipients. Social support has been conceptualized as a protective factor that partially accounts for differences in HRQOL. This study compares the HRQOL of children with pacemakers with that of healthy children, and examines associations between HRQOL and social support. Twenty-seven pediatric pacemaker recipients completed measures of HRQOL and social support. Their parents also completed measures of child HRQOL. High concordance was found for child and parent-proxy reports of child HRQOL. Children with pacemakers and their parents both reported relatively low child HRQOL when compared to published normative data for healthy children and parents of healthy children. Family and friends emerged as the sources of support positively associated with the greatest number of HRQOL domains. In conclusion, these findings suggest that pediatric pacemaker recipients experience lower levels of HRQOL compared to healthy peers, and that social support from those closest to the child is associated with their perceived HRQOL.     

The joint flanker effect: Less social than previously thought

Research on joint action has been taken to suggest that actors automatically co-represent the tasks and/or actions of co-actors. However, recent findings on the joint Simon effect have provided evidence for a nonsocial account, which renders automatic co-representation unlikely. In the present study, we aimed to test whether a nonsocial account is also feasible for the joint version of the flanker task. In particular, we manipulated the social nature of the “co-actor” who could be another human or a Japanese waving cat. Contrary to the social interpretation of the joint flanker effect, the results demonstrated a “joint” flanker effect, irrespective of whether participants shared the task with another person or with the Japanese waving cat.     

Twenty Years of the Journal of Clinical Psychology in Medical Settings: We Hope You Will Enjoy the Show

The 20th anniversary of the Journal of Clinical Psychology in Medical Settings is celebrated by highlighting the scientist-practitioner philosophy on which it was founded. The goal of the Journal—to provide an outlet for evidence-based approaches to healthcare that underscore the important scientific and clinical contributions of psychology in medical settings—is discussed. The contemporary relevance of this approach is related to the current implementation of the Patient Protection and Affordable Care and its focus on accountability and the development of an interprofessional healthcare workforce; both of which have been foci of the Journal throughout its history and will continue to be so into the future. Several recommendations of future topic areas for the Journal to highlight regarding scientific, practice, policy, and education and training in professional health service psychology are offered. Successfully addressing these topics will support the growth of the field of psychology in the ever evolving healthcare system of the future and continue ensure that the Journal is a key source of professional information in health service psychology.     

The impact of telework on emotional experience: When,and for whom,does telework improve daily affective well-being?

Teleworking has become increasingly popular in organizations around the world. Despite this trend towards working outside of the traditional office setting, research has not yet examined how people feel (i.e., their affective experiences) on days when working at home versus in the office. Using a sample of 102 employees from a large US government agency, we employed a within-person design to test hypotheses about the relationship between teleworking and affective well-being. We also examined four individual differences (openness to experience, rumination, sensation seeking, and social connectedness outside of work) as cross-level moderators. Results show that employees experience more job-related positive affective well-being (PAWB) and less job-related negative affective well-being (NAWB) on days when they were teleworking compared to days they were working in the office. Findings show that several of the individual differences moderated the relationships. Discussion focuses on the need to consider the affective consequences of telework and the characteristics that determine who will benefit more or less from working at home.     

Going beyond the Human: Christians and Other Transhumanists

Abstract

Today's transhumanists ask good questions about the human future. What about their answers? Is their version of transhumanism useful or acceptable to Christian theology today? No, at least not in its usual form. Transhumanism and Christianity divide on how we think about the cause of the changes that lie ahead for humanity. For transhumanists, the cause or the agent of human transcendence is technology. For Christians, it is grace, the underserved goodness of God who gives life and wholeness to the creation. Our core question is whether it is proper for Christian theology to see technology as contributing in any way to the future that a gracious God has in store for the creation. Does God work through technology? Yes. We may contribute through technology to what God is doing; but it is always God's doing.
