Observation distance and recognition of photographs of celebrities' faces

Subjects were tested to assess the distance at which they could recognize the faces of celebrities (more specifically, a set of 44 portrait photographs of movie and television actors). The set of test photographs was shown initially at a distance of 200 ft. and then closer in increments of 20 ft. When the actor in a given photograph was identified, either by name, character role, or by the movie or television show in which the actor had starred, the recognition-distance was recorded and the photograph was removed from the test set. Those which were not recognized (even at the closest distance) were not included in the data summaries or statistical analysis. In calculating recognition-distance for each photograph, the values were adjusted to reflect the distance at which recognition would have occurred if all the faces were of normal size. The upper limit for recognition, as defined by the distance above which only 10% of the faces are identified, was just over 160 ft. for women, and just under 200 ft. for men. There was also a significant difference in mean recognition distance between women and men. The large range of recognition-distance (across photographs and across subjects) argues that the distance is not controlled primarily by the feature detail provided in a given photograph or by the discrimination and recall skills of the observer. More likely it is a function of diverse memory associations, so that the distance at which each photograph is recognized will depend on such factors as frequency and recency of exposure, perceived attractiveness, and how much the subject admires the celebrity.     

Cognition and Emotion over twenty-five years

In the 25 years since its foundation, Cognition and Emotion has become a leading psychological journal of research on emotion. Here we review some of the ways in which this has occurred. Questions have included how parallel systems of cognition and emotion can operate in emotion regulation and psychological therapies (including the issue of free will), how the cognitive approach to emotion works, how emotion affects attention, memory, and decision making, and how emotion research is moving beyond the individual mind into the space of the interpersonal.     

Social marketing,parental purchasing decisions,and unhealthy food in developing countries: A Nigerian typology

Developing nations are emerging from food poverty and overcoming associated externalities such as malnutrition. However, there is a growing possibility that due to the globalization of food markets and widespread use of different marketing approaches, children immediately then become exposed to a new set of externalities associated with unhealthy food choices, such as obesity. In this article, we explore the relatively under‐researched area of the influence that marketing and packaging may have on parents' food purchasing behaviour in developing countries. We present the results of a multivariate analysis of a survey of parents in Nigeria as a case study, exploring the characteristics and attitudes of parents to develop a typology of consumers whose young children may be at risk from eating unhealthy food. In addition, we consider the role that social marketing could play in encouraging segments of parents to purchase more healthy food for their children and changing children's purchasing behaviour. While older parents appear to be more susceptible to children's food purchasing requests, younger households appear to be vulnerable to forming unhealthy consumption habits, which could create further economic, social, and humanitarian development issues as countries try to raise national incomes. The importance of segmented social marketing and globalized versus local marketing differentiation is emphasized A social marketing approach may not only reduce worrying trends relating to childhood obesity but also play a role in reducing malnutrition, as it is important that corporations and governments ensure that developing nations do not emerge from one food‐health crisis only to encounter another.

Moral error theories and folk metaethics

In this paper, I distinguish between two error theories of morality: one couched in terms of truth (ET1); the other in terms of justification (ET2). I then present two arguments: the Poisoned Presupposition Argument for ET1; and the Evolutionary Debunking Argument for ET2. I go on to show how assessing these arguments requires paying attention to empirical moral psychology, in particular, work on folk metaethics. After criticizing extant work, I suggest avenues for future research.
