Personality Traits and Eating Habits in a Large Sample of Estonians

OBJECTIVES Diet has health consequences, which makes knowing the psychological correlates of dietary habits important. Associations between dietary habits and personality traits were examined in a large sample of Estonians (N = 1,691) aged between 18 and 89 years. METHOD Dietary habits were measured using 11 items, which grouped into two factors reflecting (a) health aware and (b) traditional dietary patterns. The health aware diet factor was defined by eating more cereal and dairy products, fish, vegetables and fruits. The traditional diet factor was defined by eating more potatoes, meat and meat products, and bread. Personality was assessed by participants themselves and by people who knew them well. The questionnaire used was the NEO Personality Inventory-3, which measures the Five-Factor Model personality broad traits of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness, along with six facets for each trait. Gender, age and educational level were controlled for. RESULTS Higher scores on the health aware diet factor were associated with lower Neuroticism, and higher Extraversion, Openness and Conscientiousness (effect sizes were modest: r = .11 to 0.17 in self-ratings, and r = .08 to 0.11 in informant-ratings, ps < 0.01 or lower). Higher scores on the traditional diet factor were related to lower levels of Openness (r = -0.14 and -0.13, p < .001, self- and informant-ratings, respectively). CONCLUSIONS Endorsement of healthy and avoidance of traditional dietary items are associated with peoples personality trait levels, especially higher Openness. The results may inform dietary interventions with respect to possible barriers to diet change.

The Effect of Response Style on Self-Reported Conscientiousness Across 20 Countries:

Rankings of countries on mean levels of self-reported Conscientiousness continue to puzzle researchers. Based on the hypothesis that cross-cultural differences in the tendency to prefer extreme response categories of ordinal rating scales over moderate categories can influence the comparability of self-reports, this study investigated possible effects of response style on the mean levels of self-reported Conscientiousness in 22 samples from 20 countries. Extreme and neutral responding were estimated based on respondents’ ratings of 30 hypothetical people described in short vignettes. In the vignette ratings, clear cross-sample differences in extreme and neutral responding emerged. These responding style differences were correlated with mean self-reported Conscientiousness scores. Correcting self-reports for extreme and neutral responding changed sample rankings of Conscientiousness, as well as the predictive validities of these rankings for external criteria. The findings suggest that the puzzling country rankings of self-reported Conscientiousness may to some extent result from differences in response styles.

How People See Others Is Different From How People See Themselves: A Replicable Pattern Across Cultures

Consensus studies from 4 cultures--in Belgium, the Czech Republic, Estonia, and Germany--as well as secondary analyses of self- and observer-reported Revised NEO Personality Inventory (NEO PI-R) data from 29 cultures suggest that there is a cross-culturally replicable pattern of difference between internal and external perspectives for the Big Five personality traits. People see themselves as more neurotic and open to experience compared to how they are seen by other people. External observers generally hold a higher opinion of an individuals conscientiousness than he or she does about him- or herself. As a rule, people think that they have more positive emotions and excitement seeking but much less assertiveness than it seems from the vantage point of an external observer. This cross-culturally replicable disparity between internal and external perspectives was not consistent with predictions based on the actor-observer hypothesis because the size of the disparity was unrelated to the visibility of personality traits. A relatively strong negative correlation (r = -.53) between the average self-minus-observer profile and social desirability ratings suggests that people in most studied cultures view themselves less favorably than they are perceived by others.

Comparability of self-reported conscientiousness across 21 countries

In cross–national studies, mean levels of self–reported phenomena are often not congruent with more objective criteria. One prominent explanation for such findings is that people make self–report judgements in relation to culture–specific standards (often called the reference group effect), thereby undermining the cross–cultural comparability of the judgements. We employed a simple method called anchoring vignettes in order to test whether people from 21 different countries have varying standards for Conscientiousness, a Big Five personality trait that has repeatedly shown unexpected nation–level relationships with external criteria. Participants rated their own Conscientiousness and that of 30 hypothetical persons portrayed in short vignettes. The latter type of ratings was expected to reveal individual differences in standards of Conscientiousness. The vignettes were rated relatively similarly in all countries, suggesting no substantial culture–related differences in standards for Conscientiousness. Controlling for the small differences in standards did not substantially change the rankings of countries on mean self–ratings or the predictive validities of these rankings for objective criteria. These findings are not consistent with mean self–rated Conscientiousness scores being influenced by culture–specific standards. The technique of anchoring vignettes can be used in various types of studies to assess the potentially confounding effects of reference levels. Copyright

Longitudinal Associations of Cognitive Ability, Personality Traits and School Grades with Antisocial Behaviour

This study investigated the role of adolescents’ cognitive ability, personality traits and school success in predicting later criminal behaviour. Cognitive ability, the five–factor model personality traits and the school grades of a large sample of Estonian schoolboys (N = 1919) were measured between 2001 and 2005. In 2009, judicial databases were searched to identify participants who had been convicted of misdemeanours or criminal offences. Consistent with previous findings, having a judicial record was associated with lower cognitive ability, grade point average, agreeableness, and conscientiousness and higher neuroticism. In multivariate path models, however, the contributions of cognitive ability and conscientiousness were accounted for by school grades and the effect of neuroticism was also accounted for by other variables, leaving grade point average and agreeableness the only independent predictors of judicial record status.

The tonal component of Estonian quantity in native and non-native perception

Abstract This paper focuses on the role of the pitch cue in the perception of Estonian quantity degrees. The significance of the tonal component is investigated through comparison of native vs. learned identification of the quantities. The study reports on perception tests with manipulated natural speech stimuli given to Estonian native (L1) listeners and non-native (L2) listeners with different language backgrounds. Our earlier results [Lippus, P., Pajusalu, K., & Allik, J. (2007). The tonal component in perception of the Estonian quantity. In J. Trouvain, & Barry, W. J. (Eds.), The proceedings of the 16th international congress of phonetic sciences: 16th international congress of phonetic sciences , Saarbrucken, Germany, 6–10 August 2007 (pp. 1049–1052)] showed that native Estonian listeners use pitch as an important cue for perceiving the overlong quantity (Q3), but the cue plays no significant role for L2 listeners. In this study we analyze more closely the effect of the listeners’ native language on the perception of Estonian quantities. Finnish and Russian L1 listeners successfully learn the Estonian three-way quantity distinction without considering the pitch cue. Latvian L1 listeners show some confusion between the long and overlong quantity degree, which could be explained by reference to the tonal and temporal contrasts in their native language.

Personality Profiles and the “Russian Soul”: Literary and Scholarly Views Evaluated:

Many domestic and foreign observers have claimed that Russians have a unique constellation of personality traits that mirrors their distinctive historical and cultural experience. To examine the hypothesized uniqueness of Russian personality, members of the Russian Character and Personality Survey collected data from 39 samples in 33 administrative areas of the Russian Federation. Respondents (N = 7,065) identified an ethnically Russian adult or college-aged man or woman whom they knew well and rated the target using the Russian observer-rating version of the Revised NEO Personality Inventory. The mean personality profile of Russians was very similar to the international average based on 50 different countries, debunking the myth of a unique Russian soul.The small variations from world norms did not converge with depictions of Russian national character in fiction and the scholarly literature. New items intended to capture distinctive, emic aspects of Russian personality provided no new information beyond the familiar Big Five dimensions. Religion, ethnicity, and beliefs about the uniqueness of the Russian character and the malleability of personality traits had little effect on personality ratings. Perceptions of the Russian soul do not seem to be based on the personality traits of Russians.

Obligatory averaging in mean size perception

The perception of ensemble characteristics is often regarded as an antidote to an established bottleneck in focused attention and working memory, both of which appear to be limited in capacity to a few objects only. In order to test the associative law of summation, observers were asked to estimate the mean size of four circles relative to a reference circle. When there was no time to scrutinize each individual circle, observers discriminated the mean size difference identically, irrespective of whether the same summary size increment or decrement was added to or subtracted from the size of only one, two, or all four circles. Since observers judged the size of individual circles, the position of which was indicated after they were displayed, considerably less accurately than the mean size of the four circles, it is very unlikely that explicit knowledge of the size of the individual elements is the basis of mean size judgments. The sizes of individual elements were pooled together in an obligatory manner before size information had reached awareness. The processing of size information seems to be largely constrained to only one measure at a time, with a preference for mean size rather than the individual measures from which it is assembled.

History of the Diagnosis of a Sexually Transmitted Disease is Linked to Normal Variation in Personality Traits

INTRODUCTION Stable individual differences in personality traits have well-documented associations with various aspects of health. One of the health outcomes that directly depends on peoples behavioral choices, and may therefore be linked to personality traits, is having a sexually transmitted disease (STD). AIM The study examines the associations between a comprehensive set of basic personality traits and past STD history in a demographically diverse sample. METHODS Participants were 2,110 Estonians (1,175 women) between the ages of 19 and 89 (mean age 45.8 years, SD = 17.0). The five-factor model personality traits (Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness) and their specific facets were rated by participants themselves and knowledgeable informants. Sex, age, and educational level were controlled for. MAIN OUTCOME MEASURE History of STD diagnosis based on medical records and/or self-report. RESULTS History of STD diagnosis was associated with higher Neuroticism and lower Agreeableness in both self- and informant-ratings. Among the specific personality facets, the strongest correlates of STD were high hostility and impulsiveness and low deliberation. CONCLUSIONS Individual differences in several personality traits are associated with a history of STD diagnosis. Assuming that certain personality traits may predispose people to behaviors that entail a higher risk for STD, these findings can be used for the early identification of people at greater STD risk and for developing personality-tailored intervention programs.
