Refining the relationship between personality and subjective well-being

Understanding subjective well-being (SWB) has historically been a core human endeavor and presently spans fields from management to mental health. Previous meta-analyses have indicated that personality traits are one of the best predictors. Still, these past results indicate only a moderate relationship, weaker than suggested by several lines of reasoning. This may be because of commensurability, where researchers have grouped together substantively disparate measures in their analyses. In this article, the authors review and address this problem directly, focusing on individual measures of personality (e.g., the Neuroticism-Extroversion-Openness Personality Inventory; P. T. Costa & R. R. McCrae, 1992) and categories of SWB (e.g., life satisfaction). In addition, the authors take a multivariate approach, assessing how much variance personality traits account for individually as well as together. Results indicate that different personality and SWB scales can be substantively different and that the relationship between the two is typically much larger (e.g., 4 times) than previous meta-analyses have indicated. Total SWB variance accounted for by personality can reach as high as 39% or 63% disattenuated. These results also speak to meta-analyses in general and the need to account for scale differences once a sufficient research base has been generated.     

Is the P600/SPS affected by the richness of semantic content? A linguistic ERP study in Swedish

The study investigated whether the P600/SPS component is sensitive to the richness of semantic content in sentences. ERPs were recorded while 30 native Swedish speakers read sentences, of which half were syntactically correct and half contained a syntactic violation. Both kinds of sentences came in one of three types of descending semantic completeness: semantically coherent sentences, sentences which were incoherent due to violations of selectional restrictions, or sentences of pseudo words, hence void of lexical content. In the semantically coherent sentences a P600/SPS was found for the syntactic violation. A less salient positivity was found for the violation in the semantically incoherent sentences. No P600/SPS was found for the syntactic violation in the pseudo word sentences and no LAN component in any sentence type. The results are interpreted as supporting the hypothesis that the P600/SPS component reflects a semantically based reanalysis process.     

Self-reported emotional and behavioral problems in Swedish 14 to 15-year-old adolescents: a study with the self-report version of the Strengths and Difficulties Questionnaire

The psychometric properties of the Swedish self-report version of the Strengths and Difficulties Questionnaire (SDQ-s), and the prevalence of emotional and behavioral problems as measured by the SDQ-s, were studied in 14 to 15-year-old adolescents. The psychometric properties were found to be similar to those found in other language versions, in terms of similar factor structure and acceptable test-retest stability, but low internal consistencies for some of the subscales. There was evidence of good convergent and discriminant validity. The results with regard to gender differences replicated previous findings in other countries, the girls reporting more emotional symptoms and more prosocial behavior, and the boys reporting more conduct problems and tending to report more peer problems. It is concluded that the results are in favor of using the Swedish SDQ-s as a screening instrument for adolescents, despite the low internal consistencies of some of its subscales.     

The descent of cognitive development

A constructivist theory of the evolution of cognitive development is proposed. Seven propositions are posed plus supporting evidence. Constructing fundamental physical and logicomathematical conceptual universals underlies the development of cognition in primate phylogeny, ontogeny and history. Nevertheless, diverging onset and offset ages, velocity, extent, sequencing and organization mark the evolution of cognitive development in primate phylogeny. Thus, the evolution is heterochronic, not simply recapitulatory. Converging origins followed by diverging development of primates' conceptual constructions insures species‐specific cognitive specializations. Some specializations (e.g. recursive classifying) evolved in great ape development but not in monkey development; while others (e.g. hierarchically integrated classifying) evolved in human development only. Human enculturation and language (symbolic) rearing fosters quantitative but not qualitative progress in most of chimpanzees’ developing cognition. Heterochronic evolution provided humans with the widest and most synchronic ontogenetic window of opportunity for progressive cognitive development. The descendant cognitive development – humans’ precocial, integrated and extended intellectual constructions – bridges the evolution and history of ideas.     

FISH 3: A microworld for studying social dilemmas and resource management

A Java-based microworld environment for studying resource management is described. FISH 3 may be used in research or the classroom to investigate commons dilemmas and resource dilemmas. The program uses ocean fishing as its metaphor; participants (“fishers”) experience the metaphor through both graphics (“fish” may be seen in an ocean) and text (e.g., resource replenishment is translated as “spawning”). In either stand-alone or networked modes, either with all human fishers or a mixture of human and computer fishers, 15 parameters such as the number of resource units (fish), participants (fishers), and trials (seasons), payoff values, the rate and period of resource regeneration (spawning), harvesting greed by computer fishers, awareness of other harvesters’ actions, uncertainty in the amount of the resource, operating costs, and whether the resource is visible to harvesters may be varied.
