Unfamiliar face matching: Pairs out‐perform individuals and provide a route to training

Matching unfamiliar faces is known to be difficult. Here, we ask whether performance can be improved by asking viewers to work in pairs, a manipulation known to increase accuracy for low‐level visual discrimination tasks. Across four experiments we consistently find that face matching accuracy is higher for pairs of viewers than for individuals. This ‘pairs advantage’ is generally driven by adopting the response of the higher scoring partner. However, when the task becomes difficult, both partners' performance is improved by working in a pair. In two experiments, we find evidence that working in a pair can lead to subsequent improvements in individual performance, specifically for viewers whose accuracy is initially low. The pairs' technique therefore offers the opportunity for substantial improvements in face matching performance, along with an added training benefit.     

It’s under control: Top-down search strategies can override attentional capture

Bacon and Egeth (1994) proposed that observed instances of attentional capture by feature singletons (e.g., color) were the result of a salience-based strategy adopted by subjects (singleton detection mode) and, thus, were not automatic. They showed that subjects could override capture by adopting strategies based on searching for specific target features (feature search mode). However, Theeuwes (2004) has recently argued that Bacon and Egeth’s results arose from experimental confounds. He elaborated a model in which attentional capture must be expected when salient distractors fall within a spatialwindow of attention. According to Theeuwes’s (2004) model, there exist two essential criteria for examining stimulus-driven capture. First, search latencies cannot increase with display size, since the search must be parallel; second, the salience of the irrelevant distractor must not be compromised by characteristics of the search display. Contrary to the predictions of Theeuwes’s (2004) model, we provide evidence that involuntary capture can be overridden when both of these criteria are met. Our results are consistent with Bacon and Egeth’s proposal.     

The effects of childbirth-related post-traumatic stress disorder on women and their relationships: a qualitative study

There is converging evidence that 1%-2% of women develop post-traumatic stress disorder (PTSD) as a result of childbirth. The current study aimed to explore the long-term effects of childbirth-related PTSD on women, their relationship with their partner and their relationship with their child. Semi-structured interviews were carried out with six women who reported clinically significant PTSD after birth, ranging from 7 months to 18 years beforehand. Interviews were transcribed and analysed using thematic analysis. Childbirth-related PTSD was found to have wide-ranging effects on women and their relationships. Women reported changes in physical well-being, mood and behaviour, social interaction, and fear of childbirth. Women reported negative effects on their relationship with their partner, including sexual dysfunction, disagreements and blame for events of birth. The mother-baby bond was also seriously affected. Nearly all women reported initial feelings of rejection towards the baby but this changed over time. Long-term, women seemed to have either avoidant or anxious attachments with their child. It is concluded that childbirth-related PTSD can have severe and lasting effects on women and their relationships with their partner and children. Further research is needed to compare this to normal difficulties experienced by women after having children.     

Tribespotting: a semiotic analysis of the role of consumption in the tribes of Trainspotting

• The postmodern self is so engaged with the symbolic aspects of consumption that many authors have argued that consumption defines the self. Drawing upon the literature in this area, with a particular stress on the symbolic interactionist school of thought, it is the thesis of the authors that many acts of consumption are tribal and role supporting. From this we develop a model: the rubix cube of postmodern consumption. This model places the power of self‐definition squarely on the psychic powers of the individual and not in the realms of consumption. Consumption does not define the self. Evidence, to support this view and model, is garnered from a semiotic analysis of consumption in the motion picture Trainspotting.

Sensory stimuli and e‐tailers

• This paper examines the use of sensory stimuli in the creation of store atmosphere in the online context. Parsons ( 2002 ) shows that online shoppers are motivated by many of the same non‐functional aspects of shopping as physical store shoppers (eg Tauber, 1972 ; Sheth, 1983 ), including sensory stimulation from aural and visual stimuli. This study investigates what customers desire from a virtual store atmosphere, and conducts an audit of the 15 top e‐tailers as ranked by Nielsen/NetRatings ( 2001 ) using the extant set of stimuli/responses established from the physical store literature. Findings suggest a strong desire from customers for sensory stimuli, with only partial matching by e‐tailers, and a surprising lack of differentiation among competitors. Examination of purchase responses to actual stimuli suggests a need for e‐tailers to match consumers' desires.
