Narcissism and the Strategic Pursuit of Short-Term Mating:Universal Links across 11 World Regions of the International Sexuality Description Project-2
Previous studies have documented links between sub-clinical narcissism and the active pursuit of short-term mating strategies (e.g., unrestricted sociosexuality, marital infidelity, mate poaching). Nearly all of these investigations have relied solely on samples from Western cultures. In the current study, responsesfrom a cross-cultural survey of 30,470 people across 53 nations spanning 11 world regions (North America, Central/South America, Northern Europe, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, Southeast Asia, and East Asia) were used to evaluate whether narcissism (as measured by the Narcissistic Personality Inventory; NPI) was universally associat…
Mechanisms of the national character stereotype: How people in six neighbouring countries of Russia describe themselves and the typical Russian
Altogether, 1448 individuals from six neighbouring countries of Russia in the Baltic Sea region (Finland, Estonia, Latvia, Lithuania, Poland and Belarus) described a ‘typical’ member of their own nation and a ‘typical’ Russian, as well as rated their own personality, using the National Character Survey (NCS). Results suggest that national character stereotypes are widely shared, temporally stable and moderately related to assessed personality traits, if all assessments are made using the same measurement instrument. In all studied countries, agreement between national auto‐stereotypes and assessed personality was positive and in half of the samples statistically significant. Although membe…
Harmonization of Neuroticism and Extraversion phenotypes across inventories and cohorts in the Genetics of Personality Consortium:an application of Item Response Theory
Mega- or meta-analytic studies (e.g. genome-wide association studies) are increasingly used in behavior genetics. An issue in such studies is that phenotypes are often measured by different instruments across study cohorts, requiring harmonization of measures so that more powerful fixed effect meta-analyses can be employed. Within the Genetics of Personality Consortium, we demonstrate for two clinically relevant personality traits, Neuroticism and Extraversion, how Item-Response Theory (IRT) can be applied to map item data from different inventories to the same underlying constructs. Personality item data were analyzed in >160,000 individuals from 23 cohorts across Europe, USA and Australia…
RESOLVING AMBIGUITIES IN ORIENTATION, MOTION, AND DEPTH DOMAINS
Three different perceptual systems—orientation, motion, and depth—can recover a global perceptual organization from spatially correlated random multielement patterns. In all three cases the global structure composed of random elements is evaluated by mechanisms performing measurements in the energy domain within appropriately defined local space—time areas. The selective increase in energy of one fraction of the elements may dramatically change the whole perceptual organization of the stimulus. In specially devised patterns one and the same element can belong to two or more separate perceptual organizations, the perceptual salience of one of which can be reinforced by a luminance increment…
A Big Five personality inventory in two non‐Indo‐European languages
In this study we report on two successful replications of a five‐factor personality inventory in two non‐Indo‐European languages, Estonian and Finnish, which both belong to the group of Uralic languages. Costa and McCrae's (1985) NEO Personality Inventory was adapted to these two languages. By all relevant psychometric parameters neither developed construct differs from the original construct: the reliabilities of only 11 per cent for the Estonian and 36 per cent for the Finnish subscale were lower than those of the respective NEO‐PI scales. The factor structure of both Estonian and Finnish inventories was very close to the five‐factor structure of the NEO‐PI, accounting for 71.7 per cent …
Size invariance in visual number discrimination
This study deals with the observer's ability to discriminate the numerosity of two random dot-patterns irrespective of their relative size. One of these two patterns was a reference one that was always composed of 32 dots randomly distributed within a K x K invisible square window (K = 1.92 degrees). The second one was the test pattern with one of the five magnifications (K = 0.64 degrees, 1.28 degrees, 1.92 degrees, 2.56 degrees, 3.20 degrees) and the relative number of dots varied on 11 levels (N = -15, -12, -9, -6, -3, 0, 3, 6, 9, 12, or 15 dots). The observer's task was to indicate which of the two patterns contained more dots. The results show that the stimulus size, as an irrelevant s…
