Presentation modality,rehearsal-prevention conditions,and auditory confusions in tests of short-term memory

Ss were presented four-letter sequences either auditorily or visually and asked for ordered recall after 0, 2.1, 4.2, 8.4, or 12.6 sec of digit categorization. Three different rehearsal-prevention conditions were required during presentation of the memory set: categorizing, suppressing (saying "dah"), or pronouncing each letter. Recall was worst after categorizing, best after pronouncing. Auditory presentation led to better recall after no delay but more rapid forgetting than visual presentation, regardless of the rehearsal-prevention condition. These results, and analyses of auditory confusions, are inconsistent with a view of memory which asserts that sensory information is encoded auditorily regardless of presentation modality or vocalization behavior during presentation.     

A two‐part mixed effects model for cigarette purchase task data

The Cigarette Purchase Task is a behavioral economic assessment tool designed to measure the relative reinforcing efficacy of cigarette smoking across different prices. An exponential demand equation has become a standard model for analyzing purchase task data, but its utility is compromised by its inability to accommodate values of zero consumption. We propose a two‐part mixed effects model that keeps the same exponential demand equation for modeling nonzero consumption values, while providing a logistic regression for the binary outcome of zero versus nonzero consumption. Therefore, the proposed model can accommodate zero consumption values and retain the features of the exponential demand equation at the same time. As a byproduct, the logistic regression component of the proposed model provides a new demand index, the “derived breakpoint”, for the price above which a subject is more likely to be abstinent than to be smoking. We apply the proposed model to data collected at baseline from college students (N = 1,217) enrolled in a randomized clinical trial utilizing financial incentives to motivate tobacco cessation. Monte Carlo simulations showed that the proposed model provides better fits than an existing model. We note that the proposed methodology is applicable to other purchase task data, for example, drugs of abuse.     

Subjective Cognitive Complaints and Objective Cognitive Function in Aging: A Systematic Review and Meta-Analysis of Recent Cross-Sectional Findings

Research investigating how subjective cognitive complaints (SCCs) might reliably indicate impairments in objective cognitive functioning has produced highly varied findings, and despite attempts to synthesise this literature (e.g., Jonker et al. International Journal of Geriatric Psychiatry, 15, 983–991, 2000; Reid and MacLullich Dementia and Geriatric Cognitive Disorders, 22(5–6), 471–485, 2006; Crumley et al. Psychology and Aging, 29(2), 250–263, 2014), recent work continues to offer little resolution. This review provides both quantitative and qualitative synthesis of research conducted since the last comprehensive review in 2006, with the aim of identifying reasons for these discrepancies that might provide fruitful avenues for future exploration. Meta-analysis found a small but significant association between SCCs and objective cognitive function, although it was limited by large heterogeneity between studies and evidence of potential publication bias. Often, assessments of SCCs and objective cognitive function were brief or not formally validated. However, studies that employed more comprehensive SCC measures tended to find that SCCs were associated independently with both objective cognitive function and depressive symptoms. Further explicit investigation of how assessment measures relate to reports of SCCs, and the validity of the proposed ‘compensation theory’ of SCC aetiology, is recommended.     

Maltreated and Comparison Adolescents’ Recollections of Lifetime Residences: Relationship to Delinquency and Marijuana Use

This study of child welfare-affiliated maltreated youth (n?=?216) and comparison youth (n?=?128) from the same community (age M?=?18.21, SD?=?1.42) examined: 1. whether child/caregiver characteristics and maltreatment status were associated with lifetime number of residences; and 2. whether child/caregiver characteristics, residences, and maltreatment status were associated with delinquency and marijuana use. Maltreatment status, ever living with a nonparent caregiver, and being older were associated with more residences during childhood. More residences and male sex were associated with person offense delinquency and marijuana use. It is important to help caregivers who live in disadvantaged neighborhoods, especially families with child welfare involvement, understand the behavioral consequences of a high number of residences during childhood and adolescence and provide support for stable long-term housing.     

Theory of Mind and Children's Trait Attributions about Average and Typically Stigmatized Peers

Previous research indicates that children hold negative beliefs about peers with foreign accents, physical disabilities, and people who are obese. The current study examined skills associated with individual differences in children's social judgements about these typically stereotyped groups. Theory of mind, memory, and cognitive inhibition were assessed in 3‐ to 6‐year‐olds. Then, children were asked to make trait attributions and behavioural predictions about story characters' willingness to help a peer. Results indicated that better theory of mind skills were related to greater positive trait attributions and behavioural predictions about typically stereotyped characters. Younger children made fewer positive behavioural predictions as compared to older children, but both age groups made positive trait attributions. Overall, memory and inhibition had little to no influence on children's responses, although the results varied by story type. Copyright © 2015 John Wiley & Sons, Ltd.     

Self-affirmation and affective forecasting: Affirmation reduces the anticipated impact of negative events

When forecasting how they will feel in the future, people overestimate the impact that imagined negative events will have on their affective states, partly because they underestimate their own psychological resiliency. Because self-affirmation enhances resiliency, two studies examined whether self-affirmation prior to forecasting reduces the extremity of affective forecasts. Participants in self-affirmation conditions completed a values scale or wrote an essay asserting their most important value, whereas participants in the no-affirmation condition asserted a relatively unimportant value. Participants then predicted their affective reactions to a negative or positive imagined event. In both studies, self-affirmation reduced the unpleasant affect expected to result from a negative event, but had no impact on affective forecasts for a positive event. This pattern was mediated by participants’ cognitive appraisals of the imagined event, but not by differential focus on that event. Results are consistent with self-affirmation activating or enhancing psychological resiliency to counteract immune neglect during affective forecasting of a negative event.     

The Spiritual Self‐In‐Relation: Empathy and the Construction of Spirituality Among Modern Descendants of theSpanish Crypto‐Jews

The research that is presented here explores the role that empathic attachment plays in the development of the religious self. Based on an ethnographic study of modern descendants of the Spanish crypto‐Jews, the work applies self‐in‐relation theory to the study of spirituality and religious belief acquisition among a population of individuals who, in adulthood, have modified their religious world view as a result of their crypto‐Jewish heritage. The findings of the research expand the parameters of self‐in‐relation theory in three important ways: 1) through an examination of the role that empathic attachment plays in adult conversion patterns; 2) through the elaboration of a developmental model that considers the significance of empathic attachment for sons as w ll as daughters; and 3) through an investigation into the relationship between ethnicity and spiritual development.
