Global behavioral variation: A test of differential-K

Despite Rushton’s path-breaking work into evolutionary forces affecting life history traits, not many attempts at operationalizing the differential-K spectrum at the level of countries or racial groups have been made so far. We report the construction of a “national K” factor from country-level behavioral variables. This K factor is closely related to country-level intelligence (“g”), operationalized by a composite score of IQ and scholastic achievement. We further demonstrate relationships of both g and K with measures of current environment and hypothesized evolutionary antecedents. Whereas K is predicted most powerfully by intelligence, log-transformed GDP (lgGDP) and skin reflectance, g is predicted by skin reflectance, lgGDP, cranial capacity, and a measure of evolutionary novelty.     

602 and One Dead: On Contribution to Global Poverty and Liability to Defensive Force

Abstract: When suggesting that we—the affluent in the developed world—are legitimate targets of defensive force due to our contribution to global poverty one is likely to be countered by one of two strategies. The first denies that we contribute to global poverty. The second seems to affirm that we contribute, and even that we have stringent contribution‐based duties to address this poverty, but denies that such contribution makes forcible resistance permissible. Those in this second group employ several argumentative strategies. In this paper I investigate these strategies for denying the force‐related implication of contribution to poverty. I do not argue for political violence or for the permissibility of targeting the affluent, I merely investigate a conditional: if contribution to global poverty generates stringent duties to address it, then this contribution implies permission on the part of the victims to defend themselves with force, or for third parties to use force on their behalf.     

Work performance norms and organizational efficacy as cross-level effects on the relationship between individual perceptions of self-efficacy,overcommitment, and work-related stress

In the past 10 years, there has been increasing interest in applying multilevel analysis to explain how psychosocial work conditions may influence organizational behaviour. In the present study, we investigated how the individual level variables of self-efficacy and overcommitment may relate to job stress within an analytic context controlling for the main effects of dimensions of the psychosocial work environment, as well as the employees' collective perceptions of work performance norms and organizational efficacy beliefs. The final sample consisted of 924 employees from the food and beverage industry in Norway. Hierarchical linear analysis shows that overcommitment and self-efficacy together have significant main effects on stress. As expected, the results show that overcommitment is positively related to experiences of stress and self efficacy is negatively related to work-related stress. Norms governing performance, magnitude of production, attendance, and work pressure in the workplace are directly and positively related to job stress experiences at the individual level. Contrary to our expectations we did not find a significant interaction effect of work performance norms, nor did we find main or interactional cross-level effects of organizational efficacy on stress.     

The Creative Personality: A Synthesis and Development of the Creative Person Profile

Several constructs from the research literature on the creative personality were reoperationalized to gain further understanding of the structure of the creative personality and to develop a broad measure of relevant traits (CPP—the Creative Person Profile). From an initial pool of 38 creativity relevant personality constructs, 7 factors were identified and labeled (emotional instability, ambition, associative orientation, motivation, need for originality, agreeableness, and flexibility) in a sample of 481 participants with a mean age of 31.6 years. In a subsample, there were theoretically meaningful correlations between the 5-factor model of personality and 5 of the CPP factors. Moreover, most of the 7 components correlated with at least 1 ability test or self-report criterion of creativity (creative problem solving, remote associates test, ideational fluency, items from a creative activities checklist). Finally, in a discriminant validity study, scores on the 7 factors clearly differentiated between a group of professional artists (n = 69) and the remainder of the sample, and between a group of marketing students (n = 40) and the remainder of the sample.     

Therapeutische Teams: Theorie—Empirie—Klinik (Therapeutic Teams: Theory—Research—Clinic)

Abstract

Internalized stigma has been suggested to play a major role in negative changes in identity in severe mental illness. Evidence suggests that roughly one-third of people with severe mental illness show elevated internalized stigma and that it is linked to compromised outcomes in both subjective and objective aspects of recovery. Despite substantial evidence for the impact of internalized stigma, few efforts have been made to develop professionally led treatment to address this issue. In this article, we discuss our development of a new group-based approach to the treatment of internalized stigma which we have termed “narrative enhancement and cognitive therapy (NECT)”. We describe the treatment approach and offer an illustration of it by way of a case vignette.     

C. G. Jung after ten years

Thoughts while driving on a quiet street … We were camping out in British Columbia in the most gorgeous campgrounds I'd ever seen. It was raining. We were the only campers around, as it was out of season. Driving up the coast from California to British Columbia, camping a little and staying in motels with our two children, had taken longer than we'd planned. Now, we were finally close to Victoria, and we chose to camp out instead of going to a motel. British Columbia gets a lot of rain. I realized that the lush beauty and greenery of the campgrounds were due to the rain, but it didn't occur to me that we would actually be rained upon. We were soaked by the downpour, ail of our packed clothes and bedding were very damp, and I quickly began to feel miserable.     

Political skill and emotional cue learning via voices: a training study

The ability to discern emotional expressive cues represents an important interpersonal emotional skill at the workplace. In a training study with 123 employee–peer dyads, we examined whether political skill enhances the learning of emotional expressive cues via voices. Controlling for the effects of extraversion and self‐monitoring, it was found that political skill was significantly related to the accurate recognition of emotions via voices after a training session. As predicted, other‐reported political skill was found to be a stronger predictor of such learning than self‐reported political skill. In addition, social astuteness and networking ability were the most predictive of emotional cue learning among the different dimensions of political skill. Implications and limitations are discussed.     

Is there an optimal factor structure of the Positive and Negative Syndrome Scale in patients with first‐episode psychosis?

The Positive and Negative Syndrome Scale (PANSS) is the most widely used scale to assess a variety of symptoms in patients with schizophrenia and other psychoses. The factor structure of the PANSS has been examined with confirmatory factor analyses in several studies, but not in a well‐defined first‐episode psychosis sample. The aim of this paper is to examine the statistical fit of five different PANSS models in a first‐episode, non‐affective psychosis sample. Confirmatory factor analyses were performed on PANSS data (n = 588). A main criterion for best fit was defined as the Expected Cross Validation Index (ECVI). No tested model revealed an optimally satisfactory model fit index. The Wallwork/Fortgang five‐factor model demonstrated the most optimal psychometric properties. The corresponding subscales of all evaluated five‐factor models were strongly intercorrelated. The Wallwork/Fortgang five‐factor model was found to be statistically and clinically ideal among patients with first‐episode psychosis. Therefore, we recommend this model in forthcoming studies among patients with first‐episode psychosis. However, to prevent the loss of clinically valuable information on an item level, we do not recommend removing any items from the original form. Our study also implies that the specific choice of model will not have a substantial effect on outcome results in studies on the course and outcome in first‐episode psychosis.     

Dichotic listening,executive functions and grey matter cortical volume in patients with schizophrenia and healthy controls

Schizophrenia is characterized by cognitive impairment, especially in relation to executive functions. Brain structural abnormalities are also often seen in schizophrenia although little is known of the relationship between cognitive impairment and structural brain changes. Our aim was therefore to investigate this relationship further using MRI and a dichotic listening (DL) task with simple speech sounds and with instructions to focus attention and report only from the left or right ear stimulus. When instructed to focus attention on the left ear syllable a cognitive conflict is induced requiring the allocation of executive resources to be resolved. Grey matter (GM) volume was measured with MRI from four volumes of interests (VOIs), left and right frontal and temporal cortex, respectively, and correlated with DL performance. The results showed significant differences between the groups in their ability to focus attention on and report the left ear stimulus, which was accompanied by reduced GM volume in the left frontal and right temporal lobe VOIs. There was also a significant positive correlation between left frontal GM volume and performance on the DL task, for the groups combined. The results did not support a conclusion that an impairment in cognitive function in schizophrenia was driven by an corresponding impairment in brain structure, since there were no significant correlations when the groups were analyzed separately. It is however concluded that patients with schizophrenia are impaired in executive functions and that they also show reduced GM volumes in left frontal and right temporal lobe areas, compared to healthy controls.     

Are cognitive differences between countries diminishing? Evidence from TIMSS and PISA

Cognitive ability differences between countries can be large, with average IQs ranging from approximately 70 in sub-Saharan Africa to 105 in the countries of north-east Asia. A likely reason for the great magnitude of these differences is the Flynn effect, which massively raised average IQs in economically advanced countries during the 20th century. The present study tests the prediction that international IQ differences are diminishing again because substantial Flynn effects are now under way in the less developed “low-IQ countries” while intelligence is stagnating in the economically advanced “high-IQ countries.” The hypothesis is examined with two periodically administered scholastic assessment programs. TIMSS has tested 8th-grade students periodically between 1995 and 2011 in mathematics and science, and PISA has administered tests of mathematics, science and reading between 2000 and 2009. In both TIMSS and PISA, low-scoring countries tend to show a rising trend relative to higher-scoring countries. Despite the short time series of only 9 and 16 years, the results indicate that differences between high-scoring and low-scoring countries are diminishing on these scholastic achievement tests. The results support the prediction that through a combination of substantial Flynn effects in low-scoring countries and diminished (or even negative) Flynn effects in high-scoring countries, cognitive differences between countries are getting smaller on a worldwide scale.
