Recognising faces seen alone or with others: why are two heads worse than one?

The ability to identify an unfamiliar target face from an identity lineup declines when the target is accompanied by a second face during visual encoding. This two-face disadvantage is still little studied and its basis remains poorly understood. We investigated several possible explanations for this phenomenon. Experiments 1 and 2 varied the number of potential targets (1 or 2) and the number of faces in a lineup (5 or 10) to explore if this effect arises from the number of identity comparisons that need to be made to detect a target in a lineup. We also explored if this effect arises from an uncertainty concerning which is the to-be-identified target in two-face displays, by cueing the relevant face during encoding. In experiment 3 we then examined whether the two-face disadvantage reflects the depth of face encoding or a memory effect. The results show that this effect arises from the additional comparisons that are necessary to compare two potential targets to an identity lineup when memory demands are minimised (experiment 1), but it reflects a difficulty in remembering several faces when targets and lineups cannot be viewed simultaneously (experiments 2 and 3). However, in both cases the two-face disadvantage could not be eliminated fully by cueing the target. This hints at a further possible locus for this effect, which might reflect perceptual interference during the initial encoding of the target. The implications of these findings are discussed.

Religion and politics: examining the impact of faith on political participation

This study examines the relationship between religion and political activity. It theorises religious influences on political activity and tests the impact of various religious factors on political participation in a large cross-national sample (1981–2014). This study integrates longitudinal data from the aggregated World Values Survey with country-level data in the hierarchical multilevel analysis that allows teasing out the individual-level religious influences, including membership in religious organisations, religiosity and self-identification with various religious denominations, and the country-level impacts. The temporal and spatial coverage of the data used in the study includes more than 65% of the world’s population. The seven types of political participation examined in the study include signing petitions, joining in boycotts, participating in demonstrations, taking part in unofficial strikes, occupying buildings and factories, voting and membership in political parties. We find that religion matters but not always in the expected ways. Religiosity, by itself, often serves as a deterrent rather than mobilising force for political engagement, regardless the denominational differences. It is the membership in religious organisations and other voluntary associations of a secular nature that make individuals more likely to engage in political activity.
