Emotional Valence and Perceived Event Frequency Affect Memory Accuracy for a Personally Relevant Life Event

False autobiographical remembering is known to be affected both by an event's emotional valence and its perceived frequency (PEF). Here, we present a procedure that enables the assessment of retrieval accuracy for details of an overarching personally relevant real‐life event (a graduation ceremony) while taking into account variations in both their valence and PEF. Former university students who attended the same graduation ceremony completed a questionnaire with true and false statements about the ceremony. Their task was to judge whether the event details were true. Event details were previously rated for valence (positive vs. negative) and PEF (high vs. low) and their truth status was confirmed with original video footage from the ceremony. The results showed that valence modulated the effect of PEF on memory accuracy in that a decrease in false memory judgements was observed only for negative low‐PEF (implausible) event details. These results are interpreted within the affect‐as‐information framework. Copyright © 2016 John Wiley & Sons, Ltd.     

Who Reaps the Benefits of Social Change? Exploration and Its Socioecological Boundaries

We investigated the interplay between the personality trait exploration and objective socioecological conditions in shaping individual differences in the experience of two individual‐level benefits of current social change: new lifestyle options, which arise from the societal trend toward individualization, and new learning opportunities, which accrue from the societal trend toward lifelong learning. We hypothesized that people with higher trait exploration experience a greater increase in lifestyle options and learning opportunities––but more so in social ecologies in which individualization and lifelong learning are stronger, thus offering greater latitude for exploring the benefits of these trends. We employed structural equation modeling in two parallel adult samples from Germany (N = 2,448) and Poland (N = 2,571), using regional divorce rates as a proxy for individualization and Internet domain registration rates as a proxy for lifelong learning. Higher exploration was related to a greater perceived increase in lifestyle options and in learning opportunities over the past 5 years. These associations were stronger in regions in which the trends toward individualization and lifelong learning, respectively, were more prominent. Individuals higher in exploration are better equipped to reap the benefits of current social change––but the effects of exploration are bounded by the conditions in the social ecology.     

Seeing How It Sounds: Observation,Imitation, and Improved Learning in Piano Playing

This study centers upon a piano learning and teaching environment in which beginners and intermediate piano students (N = 48) learning to perform a specific type of staccato were submitted to three different (group-exclusive) teaching conditions: audio-only demonstration of the musical task; observation of the teacher's action demonstration followed by student imitation (blocked observation); and observation of the teacher's action demonstration while alternating imitation of the task with the teacher's performance (interleaved observation). Students submitted to interleaved observation were more proficient at the learned task with no significant differences for students of different proficiency levels.     

Air pollution, cognitive deficits and brain abnormalities: a pilot study with children and dogs

Exposure to air pollution is associated with neuroinflammation in healthy children and dogs in Mexico City. Comparative studies were carried out in healthy children and young dogs similarly exposed to ambient pollution in Mexico City. Children from Mexico City (n: 55) and a low polluted city (n:18) underwent psychometric testing and brain magnetic resonance imaging MRI. Seven healthy young dogs with similar exposure to Mexico City air pollution had brain MRI, measurement of mRNA abundance of two inflammatory genes cyclooxygenase-2, and interleukin 1 beta in target brain areas, and histopathological evaluation of brain tissue. Children with no known risk factors for neurological or cognitive disorders residing in a polluted urban environment exhibited significant deficits in a combination of fluid and crystallized cognition tasks. Fifty-six percent of Mexico City children tested showed prefrontal white matter hyperintense lesions and similar lesions were observed in dogs (57%). Exposed dogs had frontal lesions with vascular subcortical pathology associated with neuroinflammation, enlarged Virchow-Robin spaces, gliosis, and ultrafine particulate matter deposition. Based on the MRI findings, the prefrontal cortex was a target anatomical region in Mexico City children and its damage could have contributed to their cognitive dysfunction. The present work presents a groundbreaking, interdisciplinary methodology for addressing relationships between environmental pollution, structural brain alterations by MRI, and cognitive deficits/delays in healthy children.     

Achievement and self-concept of students with learning disabilities

The internal/external frame of reference (I/E) model by Marsh (Am Educ Res J 23:129–149, 1986) assumes that, besides social comparisons with their classmates, students engage in intraindividual, dimensional comparisons, comparing their own achievement in one subject with their achievement in other subjects. These dimensional comparison processes are assumed to result in negative paths from achievement in one subject (e.g., math) to self-concept in another (e.g., the verbal domain). In a study with N = 270 students, we investigated the generalizability of the I/E model to students with learning disabilities. Analyses showed positive correlations between math and German achievement and positive effects of achievement in both subjects on the corresponding domain-specific self-concept. Verbal and math self-concepts were almost uncorrelated. Moreover, there were negative effects of achievement in one domain on self-concept in the other. Our results therefore indicate that the I/E model can be generalized to students with learning disabilities.     

Subjective aspects of cognitive control at different stages of processing

Although research on cognitive control has addressed the effects that different forms of cognitive interference have on behavior and the activities of certain brain regions, until recently, the effects of interference on subjective experience have not been addressed. We demonstrate that, at the level of the individual trial, participants can reliably introspect the subjective aspects (e.g., perceptions of difficulty, competition, and control) of responding in interference paradigms. Similar subjective effects were obtained for both expressed and unexpressed (subvocalized) actions. Few participants discerned the source of these effects. These basic findings illuminate aspects of cognitive control and cognitive effort. In addition, these data have implications for the study of response interference in affect and self-control, and they begin to address theories regarding the function of consciousness.     

Temperament and Psychopathy: A Dual-Pathway Model

ABSTRACT— The concept of psychopathy refers to a pattern of chronic antisocial behavior and personality features, such as emotional detachment, lovelessness, and guiltlessness, attributable in part to a temperament deficit. Historically, that deficit has been seen as a low reactivity to fear, but recent research has documented a second temperament deficit in adults that involves poor emotional and behavioral control. Both pathways are found in the child psychopathology literature, pointing to multifactorial developmental pathways from childhood to adult psychopathy.     

What to Do with a Second Chance in Life? Long-Term Experiences of Non-carriers of Huntington’s Disease

Little is known about how people’s lives are influenced when going from a 50% risk status of Huntington’s disease (HD) to no risk after performing predictive testing. In this study, 20 interviews were conducted to explore the long-term (>?5 years) experiences after receiving predictive test results as a non-carrier of HD. The results showed a broad variety of both positive and negative reactions. The most prominent positive reaction reported was feelings of relief and gratitude, of not carrying the HD mutation for themselves and for their children. Also, the non-carrier status promoted in some individuals’ significant life changes such as a wishing to have (more) children, pursuing a career or breaking up from an unhappy relationship. However, negative reactions on their psychological well-being were also described. Some had experienced psychological pressure of needing to do something extraordinary in their lives; others expressed feelings of guilt towards affected or untested siblings, resulting in sadness or clinical depression. The new genetic risk status could generate a need of re-orientation, a process that for some persons took several years to accomplish. The results of the present study show the importance of offering long-term post-result counselling for non-carriers in order to deal with the psychological consequences that may follow predictive testing.     

Employees’ perception of diversity management practices: scale development and validation

Scholars and practitioners are paying increasing attention to diversity management (DM). Despite this increase and an expanding literature, there exists a lack of psychometrically sound scales to measure DM practices and none that capture employees’ perception of DM practices (EPDMP). This dearth in literature has thus hindered DM research. To fill the gap, in the present paper, using a qualitative study and 3 quantitative studies in a sample of 590 employees across various sectors in the UK, a 9-item uni-dimensional EPDMP scale is developed and validated. Results from content adequacy, reliability, convergent, discriminant, nomological and incremental predictive validity assessments provide support for the measures use in diagnostic and theory testing efforts. This paper concludes with a discussion of the implications for theory, management practice and future research.
