Are children better witnesses than adolescents? Developmental trends in different false memory paradigms

Abstract

The current study compared older children’s (11/12-year-olds) and adolescents’ (14/15-year-olds) vulnerability to false memory creation using two different methods (i.e., the Deese/Roediger-McDermott [DRM] and memory conformity paradigms) involving neutral and negative stimuli. In line with previous research, a developmental reversal effect was found for the DRM paradigm, which means that when employing this method children displayed lower false memory levels than adolescents. However, when using the memory conformity paradigm, the opposite pattern was found, with adolescents forming fewer false memories than children. This indicates that in a co-witness context, adolescents are less prone to memory errors than children. The emotional valence of the stimuli used in both paradigms did not notably affect the production of false memories. There was no statistically significant correlation between false memories as measured by the DRM and the memory conformity paradigms. Altogether, the current study indicates that there is no single type of false memory as different experimental paradigms evoke different types of erroneous recollections. Additionally, our study corroborates past findings in the literature concerning the issue of developmental reversal, strengthening the idea that under certain circumstances children might indeed be better witnesses than adolescents.     

Measuring Romantic Love: Psychometric Properties of the Infatuation and Attachment Scales

Romantic love is ubiquitous and has major influences on people's lives. Because romantic love consists of infatuation and attachment, researchers need to be able to differentiate between these constructs when examining the behavioral, affective, cognitive, and physiological correlates of this intriguing phenomenon. Existing love questionnaires appear less suitable for measuring the two-dimensional construct of romantic love. We present here the new 20-item Infatuation and Attachment Scales (IAS) questionnaire. In Study 1, exploratory factor analyses in a Dutch-speaking sample (n = 162) revealed a clear-cut two-factor structure, with 10 infatuation and 10 attachment items loading on separate components. This two-factor structure was confirmed in a new Dutch-speaking sample (n = 214, Study 2), and in an English-speaking sample (n = 183, Study 3). In all studies, it was additionally shown that both scales possessed good convergent and discriminant validity, as well as excellent internal consistency and test-retest reliability. We argue that the IAS is a widely applicable, psychometrically sound instrument that will be useful in future research exploring the effects of infatuation and attachment on behavior, emotion, cognition, peripheral physiology, and brain functioning.     

Production planning and control for remanufacturing: literature review and analysis

This article reviews the literature on production planning and control (PPC) for remanufacturing. The objectives are threefold: to determine whether the gaps identified by Guide (Guide Jr, V.D.R., 2000. Production planning and control for remanufacturing: industry practice and research needs. Journal of Operations Management, 18, 467–483) on the subject with respect to the main complicating characteristics of remanufacturing have been fulfilled; to classify the literature based on an appropriate structure to obtain a better understanding of the subject identifying sources of future research and to provide a useful source for scholars and practitioners. Seventy-six papers were examined and classified. It was found that none of the studies deals simultaneously with all of the complicating characteristics, and that more practical research is needed. In addition it was found that we lack studies regarding forecasting and aggregate planning considering disassembly of returned products, material matching restrictions or stochastic routings, master production scheduling considering material matching restrictions or stochastic routings, ordering system and capacity planning considering material matching restrictions and inventory control and management considering stochastic routings.     

Production planning and control for remanufacturing: exploring characteristics and difficulties with case studies

Production planning and control for remanufacturing is a major managerial challenge in the operations management. Researches demonstrate the need for decision-making methods in this context, which has generated theoretical and quantitative studies. However, this area still lacks empirical studies dealing with the practical, day-to-day difficulties of remanufacturers. The purpose of this paper is to link the literature and practice in a systematic in such a way that it is possible to show the similarities and differences between theoretically listed needs and real cases, thereby extending the results of previous research. For this purpose, four case studies are considered. The cases involve original equipment manufacturers (OEM) of automotive parts that have remanufacturing operations. The results indicate that these companies have difficulties that have not been addressed to date in the literature related to the uncertainties inherent in remanufacturing. In addition, we find that these companies use simplified decision-making approaches.     

Is Materialism All That Bad? Effects on Satisfaction with Material Life, Life Satisfaction, and Economic Motivation

The literature in economic psychology and quality-of-life studies alludes to a negative relationship between materialism and life satisfaction. In contrast, the macroeconomic literature implies a positive relationship between material consumption and economic growth. That is, materialism may be both good and bad. We develop a model that reconciles these two contrasting viewpoints by asserting that materialism may lead to life dissatisfaction when materialistic people evaluate their standard of living using fantasy-based expectations (e.g., ideal expectations), which increases the likelihood that they would evaluate their standard of living negatively. In turn, dissatisfaction with standard of living increases the likelihood that they would evaluate their life negatively. However, materialistic people who evaluate their standard of living using reality-based expectations (e.g., ability expectations) are likely to feel more economically motivated than their non-materialistic counterparts, and this economic motivation is likely to contribute significantly and positively to life satisfaction. Survey data were collected from seven major cities each in a different country (Australia, Bosnia/Herzegovina, Germany, Egypt, Korea, Turkey, and the USA) using a probability sample (cluster sampling method involving income stratification). The results provide support for the model. The economic public policy implications concerning how people evaluate their standard of living using ability-based expectations are discussed in the context of the ideals of meritocracy.     

Linking Advertising,Materialism, and Life Satisfaction

This paper develops theory related to advertising, materialism, and life satisfaction by formally testing explanations related to the antecedents and consequences of materialism. Survey data were collected from seven major cities each in a different country (Australia, Bosnia/Herzegovina, Germany, Egypt, Korea, Turkey, and the USA) using a probability sample (cluster sampling method involving income stratification). The results showed that the extent to which advertising is perceived to be materialistic contributes to materialism. Materialism, in turn, leads to the frequent use of various standards of comparison in making judgments about standard of living. As judgments about standard of living increase, standard of living is evaluated more negatively. In turn, negative self-evaluations contribute significantly to dissatisfaction with life.     

A life satisfaction measure: Additional validational data for the Congruity Life Satisfaction measure

Meadowet al. (1992) have developed a measure of life satisfaction based on judgment theory, referred to as Congruity Life Satisfaction (CLS). This paper reports the results of a major study involving six samples from different countries testing the construct validity of the CLS measure. The results of these studies provide additional validational support for the CLS measure.     

Pareto utility

In searching for an appropriate utility function in the expected utility framework, we formulate four properties that we want the utility function to satisfy. We conduct a search for such a function, and we identify Pareto utility as a function satisfying all four desired properties. Pareto utility is a flexible yet simple and parsimonious two-parameter family. It exhibits decreasing absolute risk aversion and increasing but bounded relative risk aversion. It is applicable irrespective of the probability distribution relevant to the prospect to be evaluated. Pareto utility is therefore particularly suited for catastrophic risk analysis. A new and related class of generalized exponential (gexpo) utility functions is also studied. This class is particularly relevant in situations where absolute risk tolerance is thought to be concave rather than linear.     

A method for assessing residents' satisfaction with community-based services: a quality-of-life perspective

A method for assessing residents' satisfaction with community-based services is developed and tested using four samples. The method is based on the theoretical notion that consumer satisfaction with individual government services (e.g., police, fire/rescue, and library), business services (e.g., banking/savings, insurance, and department stores), and nonprofit services (e.g., alcohol/drug abuse services, crisis intervention, and religious services) affect satisfaction with the community at large (global community satisfaction). Ultimately, this global community satisfaction, together with satisfaction with other relevant life domains (work, family, leisure, etc.), affect global life satisfaction. The theoretical notions are explained using bottom-up spillover theory -- a theory highly established in quality-of-life research. This theory applied to the proposed method explains that residents' overall satisfaction with a community can be decomposed into a variety of sub-domains, each of which contributes to their overall feelings about the community. Survey data from four different communities were collected to test the validity of the method. The results provided support to the model and the assessment method and measures used. From a managerial perspective, we showed how the model and the assessment method can be used by community leaders to tap citizens' perception of community quality-of-life and its determinants, identify strategic gaps or problem areas, and take corrective action.
