Gender rating gap in online reviews.

Although online reviews are used by many people to make decisions, these reviews may be biased. On the basis of 1.2 billion observations across five leading online review platforms and two lab studies (n = 1,172 and n = 1,165; US respondents fluent in English), we provide evidence for a consistent and systematic gender rating gap: women's mean online review ratings are significantly more favourable than men's.

Emotion and motion: Toward emotion recognition based on standing and walking.

Emotion recognition is key to interpersonal communication and to human-machine interaction. Body expression may contribute to emotion recognition, but most past studies focused on a few motions, limiting accurate recognition. Moreover, emotions in most previous research were acted out, resulting in non-natural motion, which is unapplicable in reality.

Help others-be happy? The effect of altruistic behavior on happiness across cultures.

Research has established that altruistic behavior increases happiness. We examined this phenomenon across cultures, differentiating between individualistic and collectivist cultures. We propose that cultural variations in the notion of altruism lead to different effects of helping on the helper's happiness.

Preferences don't have to be personal: expanding attitude theorizing with a cross-cultural perspective.

Attitudes, theorized as behavioral guides, have long been a central focus of research in the social sciences. However, this theorizing reflects primarily Western philosophical views and empirical findings emphasizing the centrality of personal preferences. As a result, the prevalent psychological model of attitudes is a person-centric one.

Higher motivation - greater control? The effect of arousal on judgement.

This research examines control over the effect of arousal, a dimension of affect, on judgement. Past research shows that high processing motivation enhances control over the effects of affect on judgement. Isolating and studying arousal as opposed to valence, the other dimension of affect, and its effect on judgement, we identify boundary conditions for past findings.

Impression Management in Survey Responding: Easier for Collectivists or Individualists?

Three experiments indicate that when individualists and collectivists engage in impression management on self-reports, they do so through different psychological mechanism s. Collectivists do so through a relatively automatic process. Thus, they can impression manage even when cognitively busy.
