Refining CVLT-II recognition discriminability indices to enhance the characterization of recognition memory changes in healthy aging

The present study examined age-related differences on the four false-positive (FP) error subtypes found on the California Verbal Learning Test-Second Edition yes/no recognition memory trial and the influence of these subtypes on source and novel recognition discriminability (SoRD and NRD, respectively) index calculations. Healthy older (n = 55) adults generally made more FP errors than healthy young adults (n = 57). Accordingly, older adults performed worse than young adults on all SoRD and NRD indices. However, the manner in which FP error subtypes were incorporated into SoRD and NRD index calculations impacted the magnitudes of observed differences between and within the two age groups on SoRD and NRD indices. The present findings underline the importance of examining FP errors in assessments of recognition memory abilities, and using more refined indices of recognition discriminability to further elucidate the nature of age-related recognition memory impairment.     

‘Language of the past’ – Exploring past tense disruption during autobiographical narration in neurodegenerative disorders

Compromised retrieval of autobiographical memory (ABM) is well established in neurodegenerative disorders. The recounting of autobiographical events is inextricably linked to linguistic knowledge, yet no study to date has investigated whether tense use during autobiographical narration is disrupted in dementia syndromes. This study investigated the incidence of correct past tense use during ABM narration in patients with Alzheimer's disease (AD, n = 10) and semantic dementia (SD, n = 10) in comparison with healthy older Controls (n = 10). Autobiographical narratives were analysed for episodic content (internal/external) and classified according to tense use (past/present). Across both patient groups, use of the past tense was significantly compromised relative to Controls, with increased levels of off‐target present tense verbs observed. Voxel‐based morphometry analyses based on structural MRI revealed differential associations between past tense use and regions of grey matter intensity in the brain. Bilateral temporal cortices were implicated in the SD group, whereas frontal, lateral, and medial temporal regions including the right hippocampus emerged in AD. This preliminary study provides the first demonstration of the disruption of specific linguistic constructs during autobiographical narration in AD and SD. Future studies are warranted to clarify at what point in the disease trajectory such deficits in tense use emerge, and whether these deficits are a product or contributing factor in memory disruption in these syndromes.     

Effects of frustration justification on hostile aggression

The present study tested Berkowitz' [1989: Psychological Bulletin 106:59-73] reformulation of the frustration-aggression hypothesis which states that any negative or aversive stimulus such as frustration, even if justified, will result in some measurable tendency to aggress, Participants' attainment of an expected gratification was either blocked in an unjustified manner, blocked in a justified manner, or not blocked at all. Degree of hostile aggression directed at the frustrating individual was measured. As predicted, justified frustration produced less hostile aggression than unjustified frustration, but even justified frustration produced more hostile aggression than no frustration at all. Results support Berkowitz' frustration-aggression reformulation. © 1995 Wiley-Liss, Inc.     

Father-adolescent relationships and the role of genotype-environment correlation.

This study uses 2 samples of adolescents and parents--the child-based Nonshared Environment in Adolescent Development project (NEAD; D. Reiss, J. M. Neiderhiser, E. Hetherington, & R. Plomin, 2000; N = 395 families) and the parent-based Twin and Offspring Study in Sweden (TOSS; N = 909 twin family pairs)--to investigate passive and evocative genotype-environment correlation (rGE) on fathering. Both samples used the same measures of positivity, negativity, control, and monitoring. A previous report examining mothering found evidence for passive rGE for positivity and monitoring, and evocative rGE for negativity and control, although both types of rGE were suggested in many cases. The current report focuses on fathering. Father reports of positivity and control are influenced by evocative rGE, whereas father reports of negativity and monitoring are influenced by both passive and evocative rGE. Adolescent reports of father's positivity and negativity were influenced by both evocative and passive rGE, and control and monitoring by passive rGE. The most notable difference in findings for fathers and mothers is for positivity and the presence of rGE for father's control and monitoring. These findings and their implications are discussed.     

Assessments of equivocal salesperson behavior and their influences on the quality of buyer-seller relationships

Abstract

In buyer-supplier relationships, salespeople engage in behaviors that buyers may (or may not) view as deceptive. Despite the salesperson’s underlying miscreant or innocent motives, buyers have a difficult time attributing the intentionality of salesperson behaviors after the fact. While extant research has explicated various governance mechanisms to mitigate the occurrence of opportunistic behaviors a priori, scholarship is not as well-versed in understanding (a) the relational factors that influence the buyer’s interpretation of debatably opportunistic salesperson behaviors and (b) the buyer’s retributive response within the ongoing relationship. To bring clarity to these issues, the authors examine relationship factors that influence the likelihood of perceived salesperson opportunism following equivocal salesperson acts. Utilizing data from industrial buyers in the U.S. healthcare industry, this study shows that buyer specific investments are related positively to attributions of salesperson guile, whereas contractual agreements are related negatively to attributions of guile. Relationship solidarity moderates these effects. Further, we find that attributions of salesperson guile lead to perceived salesperson opportunism, which in turn results in buyers lowering their expectations of relationship continuity and increasing their retributive responses. We corroborate these findings with cross-sectional survey data from a sample of industrial buyers. Collectively, these findings hold implications with regard to the role of the buyer’s attribution of salesperson guile for a specific behavior as a determinant of perceived opportunism in general, while also outlining conditions under which buyers are inclined to engage in retributive opportunism.     

Does a Gatekeeper Suicide Prevention Program Work in a School Setting? Evaluating Training Outcome and Moderators of Effectiveness

The current study sought to evaluate the suicide prevention gatekeeper training program QPR (Question, Persuade, and Refer) among school personnel using a non‐equivalent control group design. Substantial gains were demonstrated from pre‐ to post‐test for attitudes, knowledge, and beliefs regarding suicide and suicide prevention. Exploratory analyses revealed the possible moderating effects of age, professional role, prior training, and recent contact with suicidal youth on QPR participants' general knowledge, questioning, attitudes toward suicide and suicide prevention, QPR quiz scores, and self‐efficacy. The need for replication using a more rigorous experimental design in the context of strong community collaboration is discussed.     

With or without you: The impact of partner presence and attachment on exploration

Past research has examined the link of attachment anxiety and avoidance with exploration in adults, though results have been inconsistent and have relied primarily on self-reports. We hypothesized that the presence of the attachment figure (i.e., romantic partner) would play a critical moderating role on exploration duration and enjoyment. Eighty-six couples were randomly assigned to explore alone or with the partner in order to examine the moderating effect of partner presence on the effects of individuals' anxiety and avoidance as well as the partner's anxiety and avoidance. Consistent with hypotheses, there were significant two-way interactions of partner presence with anxiety, avoidance, and partner anxiety. When exploring alone, more (vs. less) anxious individuals spent less time exploring and felt less positive affect. When exploring with the partner, more (vs. less) avoidant individuals spent less time exploring and felt less positive affect. Individuals with more anxious partners felt more positive affect after exploring alone than with the partner, whereas individuals with more avoidant partners were not affected by the partner's presence. Above and beyond individuals' attachment style, partner presence and partner attachment style have implications for exploratory behavior.     

Perfectionism Dimensions and the Five‐factor Model of Personality

This study of university students (n = 357) and community adults (n = 223) examined personal standards (PS) and evaluative concerns (EC) higher‐order dimensions of perfectionism that underlie several measures from three different theoretical frameworks. In both students and community adults, confirmatory factor analyses supported PS perfectionism and EC perfectionism higher‐order latent factors. In relation to the revised NEO Personality Inventory, PS perfectionism was primarily related to conscientiousness and achievement striving. In contrast, EC perfectionism was primarily related to neuroticism, and lower positive emotions, trust and competence. EC perfectionism accounted for unique variance in current depressive and anxious symptoms over and above the five‐factor domain scores. Copyright © 2011 John Wiley & Sons, Ltd.
