The negativity bias: conceptualization, quantification, and individual differences.
There is an extensive literature on the negativity bias, including its conceptualization, measurement, temporal stability (individual differences), and neural and genetic associations. Hibbing et al. posit that the difference across individuals in the negativity bias is a key factor in determining political predisposition. The measures and paradigms developed in this literature provide a means ...
متن کاملAll in the first glance: first fixation predicts individual differences in valence bias.
Surprised expressions are interpreted as negative by some people, and as positive by others. When compared to fearful expressions, which are consistently rated as negative, surprise and fear share similar morphological structures (e.g. widened eyes), but these similarities are primarily in the upper part of the face (eyes). We hypothesised, then, that individuals would be more likely to interpr...
متن کاملCorrugator muscle responses are associated with individual differences in positivity-negativity bias.
Corrugator supercilii muscle activity is considered an objective measure of valence because it increases in response to negatively valenced facial expressions (angry) and decreases to positive expressions (happy). The authors sought to determine if corrugator activity could be used as an objective measure of positivity-negativity bias. The authors recorded corrugator responses as participants r...
متن کاملInvestigating the efficacy of attention bias modification in reducing high spider fear: The role of individual differences in initial bias
BACKGROUND AND OBJECTIVES Attention Bias Modification (ABM) targets attention bias (AB) towards threat and is a potential therapeutic intervention for anxiety. The current study investigated whether initial AB (towards or away from spider images) influenced the effectiveness of ABM in spider fear. METHODS AB was assessed with an attentional probe task consisting of spider and neutral images p...

Disputes between those holding differing political views are ubiquitous and deep-seated, and they often follow common, recognizable lines. The supporters of tradition and stability, sometimes referred to as conservatives, do battle with the supporters of innovation and reform, sometimes referred to as liberals.
