Limits of the Retrieval-Inhibition Construct: List Segregation in Directed Forgetting

The authors hypothesized that retrieval inhibition in list method directed forgetting could be improved by presenting a task that maximized the segregation step of the retrieval-inhibition process. In Experiment 1, they presented lists of semantically related words in a list method directed-forgetting task to maximize retrieval inhibition. Contrary to predictions, this manipulation eliminated the directed-forgetting effect. The authors further investigated the results of Experiment 1 in Experiments 2 and 3 by manipulating recall instructions and by presenting lists that contained both a categorized and an unrelated list-half. They found directed-forgetting effects for semantically related word lists when participants were asked to recall only the TBR (to-be-remembered) items but not when participants were asked to recall both the TBF (to-be-forgotten) and TBR items. They also found that directed-forgetting effects were not produced when categorized items were presented in the 1st list.     

Are personality disorders associated with social welfare burden in the United States?

This study examined the association between personality disorders and use of major social welfare services in a nationally representative sample of U.S. adults (N = 43,093). Social welfare services received and diagnoses of personality, substance use, mood, and anxiety disorders were assessed with the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV-version. Analyses quantified the association between personality disorders and forms of public assistance while controlling for numerous confounds. Logistic regression analyses revealed dependent personality disorder, paranoid personality disorder, antisocial personality disorder, and avoidant personality disorder were significantly associated with increased odds of receiving public assistance. In contrast, persons diagnosed with histrionic, schizoid, and obsessive-personality disorder were not significantly more likely to receive any public welfare service. Development of effective prevention and treatment of personality disorders would likely lead to reductions in overall social welfare burden.

Musical rhythm discrimination explains individual differences in grammar skills in children

This study considered a relation between rhythm perception skills and individual differences in phonological awareness and grammar abilities, which are two language skills crucial for academic achievement. Twenty‐five typically developing 6‐year‐old children were given standardized assessments of rhythm perception, phonological awareness, morpho‐syntactic competence, and non‐verbal cognitive ability. Rhythm perception accounted for 48% of the variance in morpho‐syntactic competence after controlling for non‐verbal IQ, socioeconomic status, and prior musical activities. Children with higher phonological awareness scores were better able to discriminate complex rhythms than children with lower scores, but not after controlling for IQ. This study is the first to show a relation between rhythm perception skills and morpho‐syntactic production in children with typical language development. These findings extend the literature showing substantial overlap of neurocognitive resources for processing music and language.

Views on Aging: How Caring for an Aging Parent Influences Adult Daughters’ Perspectives on Later Life

Approximately 24 million Americans provide informal (unpaid) care to a family member or friend who is disabled or ill. The most common informal caregiving relationship is that of an adult child providing assistance to an elderly parent. Women in midlife represent most of the unpaid caregivers for older adults, yet little is known about how providing care affects women’s beliefs about and desires for their own aging. The purpose of this study was to understand how being a caregiver affected adult daughters’ perspectives on their own late life. In-depth interviews were conducted with a diverse sample of 15 women between the ages of 50 and 65 who were providing care to an ill and disabled parent or parent-in-law. Analysis of the qualitative data revealed that caregivers were affected by the caregiving experience in five ways: gaining awareness, provoking fears, providing a comparison for current functioning, providing firsthand knowledge about aging, and providing an example of how to age. This study offers an alternative perspective on the well-documented negative consequences of caring for an older person, suggesting that caregiving encourages personal growth for adult daughters in midlife.     

Functional principal components analysis of workload capacity functions

Workload capacity, an important concept in many areas of psychology, describes processing efficiency across changes in workload. The capacity coefficient is a function across time that provides a useful measure of this construct. Until now, most analyses of the capacity coefficient have focused on the magnitude of this function, and often only in terms of a qualitative comparison (greater than or less than one). This work explains how a functional extension of principal components analysis can capture the time-extended information of these functional data, using a small number of scalar values chosen to emphasize the variance between participants and conditions. This approach provides many possibilities for a more fine-grained study of differences in workload capacity across tasks and individuals.     

Sovereign Debt

This essay examines the concept of sovereign debt in both political‐economic and theological registers. Elaborating the dynamics of monetary economy, I demonstrate how postures of indebtedness characterize the relationship between sovereign power and the governed. While taxation signals the debt of obedience and fealty owed to sovereignty, the monetary circuit reveals that sovereign power exists in a state of indebtedness to the governed. The morally valenced proximity between debt and guilt helps to perpetuate such relations. Tracing these resonances and resemblances in the theological realm, I consider the centrality of debt as a structuring principle in key soteriological traditions within Christian thought. Not only does God appear to uphold debt logic, but God, I claim, becomes identified with debt and marked as a debtor. The divine sovereign as debtor and as enforcing debt provides cues for earthly sovereigns and legitimates cultures of debt. In light of the theopolitical legacy in the West, the mutual influence between theology and the political realm, refiguring this set of influential theological concepts may prove helpful in decentering debt as a governing principle in modern life.     

There are many ways to be rich: Effects of three measures of semantic richness on visual word recognition

Previous studies have reported that semantic richness facilitates visual word recognition (see, e.g., Buchanan, Westbury, & Burgess, 2001; Pexman, Holyk, & Monfils, 2003). We compared three semantic richness measures--number of semantic neighbors (NSN), the number of words appearing in similar lexical contexts; number of features (NF), the number of features listed for a word's referent; and contextual dispersion (CD), the distribution of a word's occurrences across content areas-to determine their abilities to account for response time and error variance in lexical decision and semantic categorization tasks. NF and CD accounted for unique variance in both tasks, whereas NSN accounted for unique variance only in the lexical decision task. Moreover, each measure showed a different pattern of relative contribution across the tasks. Our results provide new clues about how words are represented and suggest that word recognition models need to accommodate each of these influences.
