Sex Really Does Sell: The Recall of Sexual and Non‐sexual Television Advertisements in Sexual and Non‐sexual Programmes

The present study examined memory for advertisements as a function of both advertisement content and the contextual programme content. Participants were randomly assigned to one of two conditions: in one condition, they watched a sexual programme and in the other a non‐sexual programme. Embedded within each programme were the same highly sexual and non‐sexual advertisements that had been matched in pairs for five products. Memory for the advertisements and involvement in the programmes was measured. It was found that on three indices (free recall, brand recognition and prompted recall), memory for the sexual advertisements was superior to that for non‐sexual advertisements. There was no effect of the programme content on advertisement recall and no relationship between programme involvement and advertisement recall. The results are discussed with reference to extant literature on memory for advertisements. Copyright © 2015 John Wiley & Sons, Ltd.     

Effects of program‐advertisement congruity and advertisement emotional appeal on memory for health and safety advertisements

The aim of this study was to examine the memory for health and safety advertisements (HSAs) embedded within a congruent (documentary) or incongruent (sitcom) program. A total of 80 participants aged 16–25 years took part. Participants watched either a sitcom or a health‐related program with health and safety and “filler” advertisements. After they watched the 30 minute program, they were given free and cued recall measures as well as program evaluation. These showed that the free recall scores were generally better for HSAs than filler advertisements across both program types, while the cued recall and advertisement recognition scores were better for filler advertisements than HSAs. Memory scores revealed that the HSAs were better remembered than filler advertisements in an incongruent program environment. Health advertisements are better recalled in non‐health‐related programs. This supported the interference hypothesis.     

Narratives,mechanisms and progress in historical science

Geologists, Paleontologists and other historical scientists are frequently concerned with narrative explanations targeting single cases. I show that two distinct explanatory strategies are employed in narratives, simple and complex. A simple narrative has minimal causal detail and is embedded in a regularity, whereas a complex narrative is more detailed and not embedded. The distinction is illustrated through two case studies: the ‘snowball earth’ explanation of Neoproterozoic glaciation and recent attempts to explain gigantism in Sauropods. This distinction is revelatory of historical science. I argue that at least sometimes which strategy is appropriate is not a pragmatic issue, but turns on the nature of the target. Moreover, the distinction reveals a counterintuitive pattern of progress in some historical explanation: shifting from simple to complex. Sometimes, historical scientists rightly abandon simple, unified explanations in favour of disunified, complex narratives. Finally I compare narrative and mechanistic explanation, arguing that mechanistic approaches are inappropriate for complex narrative explanations.     

Using robots to understand animal cognition

In recent years, robotic animals and humans have been used to answer a variety of questions related to behavior. In the case of animal behavior, these efforts have largely been in the field of behavioral ecology. They have proved to be a useful tool for this enterprise as they allow the presentation of naturalistic social stimuli whilst providing the experimenter with full control of the stimulus. In interactive experiments, the behavior of robots can be controlled in a manner that is impossible with real animals, making them ideal instruments for the study of social stimuli in animals. This paper provides an overview of the current state of the field and considers the impact that the use of robots could have on fundamental questions related to comparative psychology: namely, perception, spatial cognition, social cognition, and early cognitive development. We make the case that the use of robots to investigate these key areas could have an important impact on the field of animal cognition.

Targeting those in need: baseline data from the first English National Health Service (NHS) health trainer service

As part of a wider strategy to reduce health inequalities, England's National Health Service has introduced health trainers (HTs) to facilitate healthier behaviour among disadvantaged groups. This study reports baseline data from the first English HT service: assessing whether the HTs reached socially disadvantaged clients engaging in unhealthy behaviours and describing client belief characteristics relevant to the delivery of the service. Data from 864 clients show that the service reached disadvantaged groups and that those groups were engaging in risky health behaviours. Self-efficacy about changing behaviour was not strong and clients were unlikely to have made explicit behaviour-change plans prior to attending the service. Implications for HT services around targeting those most in need and supporting psychological triggers for change are discussed.
