The Big Five Inventory (BFI) is a self-report measure designed to assess the high-order personality traits of Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness. As part of the International Sexuality Description Project, the BFI was translated from English into 28 languages and administered to 17,837 individuals from 56 nations. The resulting cross-cultural data set was used to address three main questions: Does the factor structure of the English BFI fully replicate across cultures? How valid are the BFI trait profiles of individual nations? And how are personality traits distributed throughout the world? The five-dimensional structure was robust across major regions of the world. Trait levels were related in predictable ways to self-esteem, sociosexuality, and national personality profiles. People from the geographic regions of South America and East Asia were significantly different in openness from those inhabiting other world regions. The discussion focuses on limitations of the current data set and important directions for future research.

As part of the International Sexuality Description Project, a total of 17,804 participants from 62 cultural regions completedthe RelationshipQuestionnaire(RQ), a self-reportmeasure of adult romanticattachment. Correlational analyses within each culture suggested that the Model of Self and the Model of Other scales of the RQ were psychometrically valid within most cultures. Contrary to expectations, the Model of Self and Model of Other dimensions of the RQ did not underlie the four-category model of attachment in the same way across all cultures. Analyses of specific attachment styles revealed that secure romantic attachment was normative in 79% of cultures and that preoccupied romantic attachment was particularly prevalent in East Asian cultures. Finally, the romantic attachment profiles of individual nations were correlated with sociocultural indicators in ways that supported evolutionary theories of romantic attachment and basic human mating strategies.

Contrary to research findings previously reported in Western cultures, we found that men were not significantly more dismissing than women across all cultural regions. Gender differences in dismissing romantic attachment were evident in most cultures, but were typically only small to moderate in magnitude. Looking across cultures, the degree of gender differentiation in dismissing romantic attachment was predictably associated with sociocultural indicators. Generally, these associations supported evolutionary theories of romantic attachment, with smaller gender differences evident in cultures with high–stress and high–fertility reproductive environments. Social role theories of human sexuality received less support in that more progressive sex–role ideologies and national gender equity indexes were not cross–culturally linked as expected to smaller gender differences in dismissing romantic attachment.peer-reviewe

Classical conditioning of sexual arousal has previously been demonstrated in human males but not in females. This study explored the role of classical (Pavlovian) conditioning in the activation of genital sexual arousal in both women and men, and assessed the effects of varying conditioned stimulus (CS) duration (subliminal/conscious) and relevance (sexually relevant/irrelevant). Twenty-seven female and 29 male participants received either subliminal or conscious presentations of a photograph of either a sexually relevant (abdomen of the opposite sex) or irrelevant (gun) CS+, which was followed by the unconditioned stimulus (US-erotic film clip). A CS-, a stimulus not paired with the US, was also included in the 11 conditioning trials. Ten participants were assigned to a control group that received unpaired presentations of the CS+, CS-, and the US. Both women and men showed more evidence of conditioning to the abdomen than to the gun when the CS was presented subliminally. When consciously perceived CSs were used, however, gender differences emerged. Men again showed the expected cue-to-consequence specificity but women showed the opposite effect, that is, conditioned arousal to the sexually irrelevant rather than to the relevant CS. The latter finding may be due to increased autonomic nervous system arousal associated with the irrelevant CS (gun). Skin conductance responses indicated more general arousal to the gun than to the male abdomen in women. This is the first study to compare the effects of a subliminal and conscious CS and to find classical conditioning of sexual arousal in women.
