Assessment of affect integration: validation of the affect consciousness construct

Affect integration, or the capacity to utilize the motivational and signal properties of affect for personal adjustment, is assumed to be an important aspect of psychological health and functioning. Affect integration has been operationalized through the affect consciousness (AC) construct as degrees of awareness, tolerance, nonverbal expression, and conceptual expression of nine discrete affects. A semistructured Affect Consciousness Interview (ACI) and separate Affect Consciousness Scales (ACSs) have been developed to specifically assess these aspects of affect integration. This study explored the construct validity of AC in a Norwegian clinical sample including estimates of reliability and assessment of structure by factor analyses. External validity issues were addressed by examining the relationships between scores on the ACSs and self-rated symptom- and interpersonal problem measures as well as independent, observer-based ratings of personality disorder criteria and the Global Assessment of Functioning (GAF) scale from the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994).     

Quality of Life Before and After Cataract Surgery: Research in a Sample of Polish Patients

The goal of this paper is to present possible change in quality of life (QoL) in older sample of people with vision disturbances. The patients were investigated twice: before (N = 193) and 4 month after the cataract surgery (N = 69), by means of the scale for vision functioning, and the Life Quality Questionnaire (Schalock & Keith, 1993) extend with the items measuring health related quality of life (HRQoL). Two problems were formulated: To what extent are visual defects associated with the decreased subjective QoL? What changes are observed in perceived QoL during the period of treatment of visual defects? The patients reported significant increase of HRQoL, however they did not report similar increase of a general QoL. Few reasons are considered: overlapping of the content of visual function scales and HRQoL and different indices of a general QoL and HRQoL, lack of a proper postoperative care, low socio-economic status of the participants, and too high expectation concerning better functioning after the surgery.

I see what you mean: theta power increases are involved in the retrieval of lexical semantic information

An influential hypothesis regarding the neural basis of the mental lexicon is that semantic representations are neurally implemented as distributed networks carrying sensory, motor and/or more abstract functional information. This work investigates whether the semantic properties of words partly determine the topography of such networks. Subjects performed a visual lexical decision task while their EEG was recorded. We compared the EEG responses to nouns with either visual semantic properties (VIS, referring to colors and shapes) or with auditory semantic properties (AUD, referring to sounds). A time-frequency analysis of the EEG revealed power increases in the theta (4-7Hz) and lower-beta (13-18Hz) frequency bands, and an early power increase and subsequent decrease for the alpha (8-12Hz) band. In the theta band we observed a double dissociation: temporal electrodes showed larger theta power increases in the AUD condition, while occipital leads showed larger theta responses in the VIS condition. The results support the notion that semantic representations are stored in functional networks with a topography that reflects the semantic properties of the stored items, and provide further evidence that oscillatory brain dynamics in the theta frequency range are functionally related to the retrieval of lexical semantic information.     

Factor structure of the Norwegian version of the WAIS-III in a clinical sample: the arithmetic problem

Confirmatory Factor Analyses (CFA) of the Wechsler Adult Intelligence Scale-III (WAIS-III) lend partial support to the four-factor model proposed in the test manual. However, the Arithmetic subtest has been especially difficult to allocate to one factor. Using the new Norwegian WAIS-III version, we tested factor models differing in the number of factors and in the placement of the Arithmetic subtest in a mixed clinical sample (n = 272). Only the four-factor solutions had adequate goodness-of-fit values. Allowing Arithmetic to load on both the Verbal Comprehension and Working Memory factors provided a more parsimonious solution compared to considering the subtest only as a measure of Working Memory. Effects of education were particularly high for both the Verbal Comprehension tests and Arithmetic.     

Memory trace stabilization leads to large-scale changes in the retrieval network: a functional MRI study on associative memory

Spaced learning with time to consolidate leads to more stabile memory traces. However, little is known about the neural correlates of trace stabilization, especially in humans. The present fMRI study contrasted retrieval activity of two well-learned sets of face-location associations, one learned in a massed style and tested on the day of learning (i.e., labile condition) and another learned in a spaced scheme over the course of one week (i.e., stabilized condition). Both sets of associations were retrieved equally well, but the retrieval of stabilized association was faster and accompanied by large-scale changes in the network supporting retrieval. Cued recall of stabilized as compared with labile associations was accompanied by increased activity in the precuneus, the ventromedial prefrontal cortex, the bilateral temporal pole, and left temporo–parietal junction. Conversely, memory representational areas such as the fusiform gyrus for faces and the posterior parietal cortex for locations did not change their activity with stabilization. The changes in activation in the precuneus, which also showed increased connectivity with the fusiform area, are likely to be related to the spatial nature of our task. The activation increase in the ventromedial prefrontal cortex, on the other hand, might reflect a general function in stabilized memory retrieval. This area might succeed the hippocampus in linking distributed neocortical representations.     

Cross-frequency coupling between neuronal oscillations

Electrophysiological recordings in animals, including humans, are modulated by oscillatory activities in several frequency bands. Little is known about how oscillations in various frequency bands interact. Recent findings from the human neocortex show that the power of fast gamma oscillations (30-150Hz) is modulated by the phase of slower theta oscillations (5-8Hz). Given that this coupling reflects a specific interplay between large ensembles of neurons, it is likely to have profound implications for neuronal processing.     

Gateways—just as important as standards: How the internet won the “religious war” over standards in Scandinavia

This article concerns the Nordunet project and its “plug.” It is a history about how the Internet “won” the “religious war” about computer communication protocol standards in Scandinavia. It teaches us important lessons about how the Nordic countries (except Denmark) became the leading ones in the adoption and use of the Internet. On a more general level this story also teaches us an important lesson about the importance of gateways in the design and establishment of large scale computer networks and information infrastructures. It is a universal truth that the development of such technologies requires standards. And that gateways are equally important. The main conclusion drawn is that what matters in the development of such technologies is to combine and balance the use of gateways and standards in a proper way. Originally trained as a computer scientist his research focuses mainly on the interplay between social and technical issues in the development and use of large-scale information systems and infrastructures—including their standards. He has worked most of his professional career within applied research institutions and industry and before moving into academia in 1997.     

Understanding the Development of Team Identification: A Qualitative Study in UN Peacebuilding Teams

Purpose

The goal of our study was to scrutinize the psychological processes that occur in individuals when developing identification with a highly diverse team.

Design/Methodology/Approach

A qualitative, theory-generating approach following the principles of grounded theory was chosen as research design. Data were obtained from 63 personal interviews with members of seven UN peacebuilding teams in Liberia and Haiti. These teams were particularly well suited for analyzing the dynamics of identification processes as they constitute extreme cases with respect to team members’ identity diversity.

Findings

Our analysis reveals four different processes that occur as individuals develop team identification (TI): enacting a salient identity, sensemaking about team experience, evaluating collective team outcomes, and converging identity.

Implications

We can show that team members engage in both individual- and collective-directed sensemaking processes during TI development, thereby using internal (i.e., other team members) and external points of reference (i.e., team-external actors) for ingroup/outgroup comparisons. Moreover, our study reveals different modes of identity convergence (i.e., active, reactive, and withdrawal) which are associated with different types of TI (i.e., deep-structured TI, situated TI, and disidentification).

Originality/Value

Although team members’ identification with their workgroup has long been considered important for effective team functioning, knowledge about its development has remained limited and largely without empirical footing from a real-world team context. Our study represents the first empirical attempt to inductively identify the processes that occur in individuals as they develop TI.
