Inhibition, Contextual Segregation, and Subject Strategies in List Method Directed Forgetting

This experiment tested alternative explanations of list method directed forgetting effects. Two word lists were studied by 135 subjects. Between lists, subjects were instructed to remember both lists (remember group), remember both lists as well as in which list words were studied (segregate group), or to forget the first list and remember the second (forget group). All subjects took both recall and recognition tests with test order varied between subjects. Among subjects who took the recall test first, the forget group showed a directed forgetting effect (poorer performance on List 1 than List 2) with both recall accuracy, recall typing time, and recognition reaction time measures. Contextual segregation of List 1 words by forget subjects was ruled out as a sufficient cause of the effect. Limited support was obtained for a differential rehearsal explanation of the effect. Within-group comparisons and findings of release from directed forgetting support inhibitory processes as the major cause of the directed forgetting effect.     

Scalable choice models

Two representational criteria for probabilistic choice models are studied. These criteria, called scalability and weak scalability, are shown to be characterized by behavioral axioms designated, respectively, as pairwise dependence and weak pairwise dependence. The former is shown to be equivalent to the order independence axiom of Tversky. In addition, structural conditions on the choice alternatives are established under which all axioms are equivalent.     

The psychological health of employed and unemployed recent graduates as a function cognitive appraisal and of coping

In the literature on the effects of unemployment on graduates two competing hypothesis have found support. On one hand graduates have higher expectations about status and occupational identity, hence being unemployed should be more distressing. On the other hand graduates have access to more personal and situational resources and should cope better with the stress of unemployment. In a study of 181 recent graduates it was found that those who were employed (n = 88) scored higher on both somatization and interpersonal sensitivity than those who were unemployed (n = 93). A large percentage also reported not being in the job to which they aspired and scored low on job commitment. The unemployed graduates had a more positive approach to problem-solving, higher achievement motivation, more perceived social support, were more assertive, and felt less hopeless than their employed peers. They also engaged in more constructive leisure activities than the employed group. The data provide tentative support for the hypothesis that graduates are better at coping with unemployment. However the indication is that any advantage to be gained is relative to the type of job occupied by the employed group to whom they are compared. The general conclusion is that opting for a job which does not meet expectations or aspirations may be more psychologically damaging in the short term than being unemployed and hopeful. This is a function of the individual's vulnerability or resistance to stress and highlights the need for graduates to be prepared more effectively for the path to a career.     

Are Better Workers Also Better Humans? On Pharmacological Cognitive Enhancement in the Workplace and Conflicting Societal Domains

The article investigates the sociocultural implications of the changing modern workplace and of pharmacological cognitive enhancement (PCE) as a potential adaptive tool from the viewpoint of social niche construction. We will attempt to elucidate some of the sociocultural and technological trends that drive and influence the characteristics of this specific niche, and especially to identify the kind of capabilities and adaptations that are being promoted, and to ascertain the capabilities and potentialities that might become diminished as a result. In this context, we will examine what PCE is, and how and why it might be desirable as a tool for adaptation within the workplace. As human beings are, or at least should be allowed to be, more than merely productive, able-bodied and able-minded workers, we will further examine how adaptation to the workplace niche could result in problems in other domains of modern societal life that require the same or other cognitive capabilities. In this context we will also focus on the concept of responsibility and how it pertains to PCE and the modern workplace niche. This will shed some light on the kind of trends related to workplace niche construction, PCE and capability promotion that we can expect in the future, and on the contexts in which this might be either beneficial or detrimental to the individual as a well-rounded human being, and to other members of society.     

An Introduction to Latent Class Growth Analysis and Growth Mixture Modeling

In recent years, there has been a growing interest among researchers in the use of latent class and growth mixture modeling techniques for applications in the social and psychological sciences, in part due to advances in and availability of computer software designed for this purpose (e.g., Mplus and SAS Proc Traj). Latent growth modeling approaches, such as latent class growth analysis (LCGA) and growth mixture modeling (GMM), have been increasingly recognized for their usefulness for identifying homogeneous subpopulations within the larger heterogeneous population and for the identification of meaningful groups or classes of individuals. The purpose of this paper is to provide an overview of LCGA and GMM, compare the different techniques of latent growth modeling, discuss current debates and issues, and provide readers with a practical guide for conducting LCGA and GMM using the Mplus software.     

"Official" Doctrine and "Unofficial" Practices: The Negotiation of Catholicism in a Netherlands Community

This article examines the Dutch Catholic Church. It is based on a qualitative ethnographic analysis of a particular Dutch Catholic community. It seeks to demonstrate that despite a decline in the church since the 1960s many Dutch parishioners are becoming active in redefining the church and attempting to revitalize Catholicism, creating democratically organized local communities where laity and local clergy, women and men, work together as equals in negotiating change, but argues that this may involve "unofficial" practices, possibly at odds with "official" church hierarchy controlled doctrine, which may resist acknowledging them and resist change. By examining these issues, the article aims to understand the dialectic and tension between what could be termed "popular" and "orthodox", "private" and "public", beliefs and to examine the constraints or possibilities this may place on the church. In this sense, the article also aims to explore how religion, thought to be vulnerable to recent change encouraging individual independence from social institutions, may negotiate (or reject) new developments. Although challenged, Catholic identity may still be valued and provide individuals with resources for negotiating new developments. However, the success or failure of this may depend on the nature of the struggle for authority and influence between "official" and "unofficial" versions of Catholicism.     

Reliability of a Longitudinal Sequence of Scale Ratings

Reliability captures the influence of error on a measurement and, in the classical setting, is defined as one minus the ratio of the error variance to the total variance. Laenen, Alonso, and Molenberghs (Psychometrika 73:443–448, 2007) proposed an axiomatic definition of reliability and introduced the R _T coefficient, a measure of reliability extending the classical approach to a more general longitudinal scenario. The R _T coefficient can be interpreted as the average reliability over different time points and can also be calculated for each time point separately. In this paper, we introduce a new and complementary measure, the so-called R _Λ , which implies a new way of thinking about reliability. In a longitudinal context, each measurement brings additional knowledge and leads to more reliable information. The R _Λ captures this intuitive idea and expresses the reliability of the entire longitudinal sequence, in contrast to an average or occasion-specific measure. We study the measure’s properties using both theoretical arguments and simulations, establish its connections with previous proposals, and elucidate its performance in a real case study.
