Gerotranscendence and wisdom in Polish older adults. The longitudinal mediation analysis of forgiveness.

Objectives: The goal of the present study was to investigate whether forgiveness played a mediating role in the relationships between gerotranscendence and wisdom among people in late adulthood. Method: The study included 416 participants aged 60 to 75 years. The following measures were used: the Gerotranscendence Scale Type 2 (GST2), the Heartland Forgiveness Scale and the Self-Assessed Wisdom Scale (SAWS). To verify the hypothesis, a longitudinal three-wave field study was conducted. Results: The results suggest that an increase in gerotranscendence is associated with an increase in forgiveness and wisdom. In addition, greater willingness to forgive co-occurs with higher levels of wisdom. Moreover, dispositional forgiveness mediates the relationship between gerotranscendence and wisdom - a higher gerotranscendence leads to a higher wisdom through an increase in forgiveness. Conclusion: The results of our research add to the knowledge of the mechanism of the relationship between gerotranscendence and wisdom and support the thesis that late adulthood presents individuals with new challenges and opportunities for creative personal development.

The Role of Machiavellianism and Interdependent Agency in Facebook Intrusion.

Facebook is one the most popular social networking sites in the world. The social aspect and perceiving oneself in the context of relationships seem to be crucial in the analysis of Facebook use. In recent years the number of Facebook users has been increasing, which is related to the problem of Facebook intrusion. Machiavellianism and selected interdependence agency indicators (conformity, relatedness, and autonomy) are associated with social functioning, which is an important aspect of Facebook intrusion. The aim of the study was to check how Machiavelianism and the interdependent agency indicators mentioned above affect Facebook intrusion and whether Facebook intrusion decreases satisfaction with life. The participants in the online study were 715 Polish Facebook users. We administered the Facebook Intrusion Scale, Conformity, Relatedness, and Autonomy Scales, and the Satisfaction With Life Scale. The results show that the selected interdependence agency indicators predict Facebook intrusion. Our results revealed that a high level of Machiavellianism was related to a high level of Facebook intrusion in women. They also show that conformity is positively and autonomy negatively related to Facebook intrusion and that Facebook decreases reduces satisfaction with life. The presented research thus contributes to knowledge about Facebook usage patterns.

The emergence of sex differences in personality traits in early adolescence: A cross-sectional, cross-cultural study.

Although large international studies have found consistent patterns of sex differences in personality traits among adults (i.e., women scoring higher on most facets), less is known about cross-cultural sex differences in adolescent personality and the role of culture and age in shaping them. The present study examines the NEO Personality Inventory-3 (McCrae, Costa, & Martin, 2005) informant ratings of adolescents from 23 cultures (N = 4,850), and investigates culture and age as sources of variability in sex differences of adolescents' personality. The effect for Neuroticism (with females scoring higher than males) begins to take on its adult form around age 14. Girls score higher on Openness to Experience and Conscientiousness at all ages between 12 and 17 years. A more complex pattern emerges for Extraversion and Agreeableness, although by age 17, sex differences for these traits are highly similar to those observed in adulthood. Cross-sectional data suggest that (a) with advancing age, sex differences found in adolescents increasingly converge toward adult patterns with respect to both direction and magnitude; (b) girls display sex-typed personality traits at an earlier age than boys; and (c) the emergence of sex differences was similar across cultures. Practical implications of the present findings are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

The Inaccuracy of National Character Stereotypes.

Consensual stereotypes of some groups are relatively accurate, whereas others are not. Previous work suggesting that national character stereotypes are inaccurate has been criticized on several grounds. In this article we (a) provide arguments for the validity of assessed national mean trait levels as criteria for evaluating stereotype accuracy; and (b) report new data on national character in 26 cultures from descriptions (N=3,323) of the typical male or female adolescent, adult, or old person in each. The average ratings were internally consistent and converged with independent stereotypes of the typical culture member, but were weakly related to objective assessments of personality. We argue that this conclusion is consistent with the broader literature on the inaccuracy of national character stereotypes.

Stereotypes of age differences in personality traits: universal and accurate?

Age trajectories for personality traits are known to be similar across cultures. To address whether stereotypes of age groups reflect these age-related changes in personality, we asked participants in 26 countries (N = 3,323) to rate typical adolescents, adults, and old persons in their own country. Raters across nations tended to share similar beliefs about different age groups; adolescents were seen as impulsive, rebellious, undisciplined, preferring excitement and novelty, whereas old people were consistently considered lower on impulsivity, activity, antagonism, and Openness. These consensual age group stereotypes correlated strongly with published age differences on the five major dimensions of personality and most of 30 specific traits, using as criteria of accuracy both self-reports and observer ratings, different survey methodologies, and data from up to 50 nations. However, personal stereotypes were considerably less accurate, and consensual stereotypes tended to exaggerate differences across age groups.

Perceptions of aging across 26 cultures and their culture-level associates.

College students (N=3,435) in 26 cultures reported their perceptions of age-related changes in physical, cognitive, and socioemotional areas of functioning and rated societal views of aging within their culture. There was widespread cross-cultural consensus regarding the expected direction of aging trajectories with (a) perceived declines in societal views of aging, physical attractiveness, the ability to perform everyday tasks, and new learning; (b) perceived increases in wisdom, knowledge, and received respect; and (c) perceived stability in family authority and life satisfaction. Cross-cultural variations in aging perceptions were associated with culture-level indicators of population aging, education levels, values, and national character stereotypes. These associations were stronger for societal views on aging and perceptions of socioemotional changes than for perceptions of physical and cognitive changes. A consideration of culture-level variables also suggested that previously reported differences in aging perceptions between Asian and Western countries may be related to differences in population structure.

Riluzole enhances the anti-seizure action of conventional antiepileptic drugs against pentetrazole-induced convulsions in mice.

Riluzole, a pre- and postsynaptic modulator of glutamate transmission, administered alone at doses of 5 and 10 mg/kg did not affect pentetrazole-evoked seizures in mice. However, it enhanced the anti-seizure action of valproate, phenobarbital, ethosuximide, although not that of clonazepam, in this model of experimental epilepsy. Keeping in mind that riluzole did not change plasma levels of antiepileptic drugs, a pharmacokinetic interaction, at least in terms of free plasma levels, does not seem probable. Regarding undesired effects, riluzole (5 mg/kg) and its combination with valproate did not produce any motor or long-term memory impairment. In contrast, the concomitant treatment of riluzole (5 mg/kg) with valproate (144 mg/kg), phenobarbital (4.9 mg/kg), or ethosuximide (90 mg/kg), resulted in a moderate motor deficit, but not long-term memory impairment in the tested mice. In conclusion, the results of the present study suggest that riluzole might occur effective as an additive drug in the treatment of myoclonic or absence epilepsy in humans.
