Philosophical Studies - Mark Johnston and Eric Olson have both pressed what Johnston has dubbed the personite problem. Personites, if they exist, are person-like entities whose lives extend over a...     

Attention and cognitive control: unfolding the dichotic listening story

In this article we present a theoretical approach to cognitive control and attention modulation, as well as review studies related to such a view, using an auditory task based on dichotic presentations of simple consonant-vowel syllables. The reviewed work comes out of joint research efforts by the 'Attention-node' at the 'Nordic Center of Excellence in Cognitive Control'. We suggest a new way of defining degrees of cognitive control based on systematically varying the stimulus intensity of the right or left ear dichotic stimulus, thus parametrically varying the degree of stimulus interference and conflict when assessing the amount of cognitive control necessary to resolve the interference. We first present an overview and review of previous studies using the so-called "forced-attention" dichotic listening paradigm. We then present behavioral and neuroimaging data to explore the suggested cognitive control model, with examples from normal adults, clinical and special ability groups.     

Framing Effects in International Relations

Framing is the least well-developed central concept of prospect theory. Framing is both fundamental to prospect theory and remarkably underdeveloped in the prospect theory literature. This paper focuses on the many subtypes and variations of framing: thematic vs. evaluative; successful vs. failed; productive vs. counterproductive; purposeful, structural and interactive framing; counterframing; loss frames vs. gain frames; revolving framing vs. sequential framing; framing by a third party; and framing vs. priming. The bulk of the paper provides an analysis of framing and framing effects in foreign policy settings with an emphasis on U.S. foreign policy. We highlight framing effects during the Cold War, the Persian Gulf War, the current ``war on terrorism', and other IR/foreign policy settings. Our examination highlights the extent to which presidents and other significant world leaders use framing to shape policy debates and national security choices.     

Pentecostal theology of mission in the making

While Pentecostals are known for productive and widespread mission work, theological reflection has not kept up with praxis. In recent years, however, a number of leading Pentecostal theologians have started to reflect on key issues such as what are the underlying motifs and distinguishing features as well as urgent challenges facing Pentecostal mission, social concern and relation to other religions, among others. This essays attempts to offer a state‐of‐art critical survey based on English speaking literature at the international level.     

Role clarity,role conflict,and vitality at work: The role of the basic needs

This study aimed to provide new information on the relationships between vitality at work and role clarity, role conflict, and psychological basic need satisfaction. Participants of the cross‐sectional study were 110 employees in a preventive intervention program. Associations between the focal constructs were examined with regression and bootstrapping analyses. The results suggest that the role clarity is associated with subjective vitality at work through higher autonomy and higher competence, and that role conflict is negatively associated with subjective vitality at work through lower autonomy and lower relatedness. Additionally, an interaction between the role characteristics was observed, suggesting that the strength of the association between role clarity and competence, and the strength of the indirect association between role clarity and vitality through competence may vary depending on the level of role conflict. The findings are consistent with the notion that that managers and co‐workers may affect the opportunities of individuals to achieve need satisfaction and feel energized by delineating and negotiating role‐related factors at work. Need satisfaction, in turn, is an antecedent of well‐being and motivation. Employees should feel able to clarify role ambiguities with their supervisor or co‐workers and thus reduce the role conflicts imposed by the expectations of various stakeholders. Limitations of the study include the self‐rating methodology, cross‐sectional design, and properties of the sample restricting generalizability.     

Working memory training revisited: A multi-level meta-analysis of n-back training studies

The efficacy of working memory (WM) training has been a controversial and hotly debated issue during the past years. Despite a large number of training studies and several meta-analyses, the matter has not yet been solved. We conducted a multi-level meta-analysis on the cognitive transfer effects in healthy adults who have been administered WM updating training with n-back tasks, the most common experimental WM training paradigm. Thanks to this methodological approach that has not been employed in previous meta-analyses in this field, we were able to include effect sizes from all relevant tasks used in the original studies. Altogether 203 effect sizes were derived from 33 published, randomized, controlled trials. In contrast to earlier meta-analyses, we separated task-specific transfer (here untrained n-back tasks) from other WM transfer tasks. Two additional cognitive domains of transfer that we analyzed consisted of fluid intelligence (Gf) and cognitive control tasks. A medium-sized transfer effect was observed to untrained n-back tasks. For other WM tasks, Gf, and cognitive control, the effect sizes were of similar size and very small. Moderator analyses showed no effects of age, training dose, training type (single vs. dual), or WM and Gf transfer task contents (verbal vs. visuospatial). We conclude that a substantial part of transfer following WM training with the n-back task is task-specific and discuss the implications of the results to WM training research.     

Brief training in mindfulness may normalize a blunted error-related negativity in chronically depressed patients

The error-related negativity (ERN), an evoked-potential that arises in response to the commission of errors, is an important early indicator of self-regulatory capacities. In this study we investigated whether brief mindfulness training can reverse ERN deficits in chronically depressed patients. The ERN was assessed in a sustained attention task. Chronically depressed patients (n = 59) showed significantly blunted expression of the ERN in frontocentral and frontal regions, relative to healthy controls (n = 18). Following two weeks of training, the patients (n = 24) in the mindfulness condition showed a significantly increased ERN magnitude in the frontal region, but there were no significant changes in patients who had received a resting control (n = 22). The findings suggest that brief training in mindfulness may help normalize aberrations in the ERN in chronically depressed patients, providing preliminary evidence for the responsiveness of this parameter to mental training.
