Some effects of token rewards on school achievement of children with Down's syndrome

The effectiveness of a token economy system in producing improvement in the academic performance of children with Down's syndrome was tested. One group of seven children received token reinforcement for correct responses and showed significant improvement both in arithmetic and language. A second matched group of six children received only verbal praise for correct responses to the same instructional materials and failed to improve in arithmetic but showed significant gains in language. Re-test scores one year later revealed that the Token Group maintained its gains in both subjects whereas the language performance of the No-Token Group showed a significant decline.     

Using unexpected questions to elicit information and cues to deceit in interpreter‐based interviews

We examined whether speech‐related differences between truth tellers and liars are more profound when answering unexpected questions than when answering expected questions. We also examined whether the presence of an interpreter affected these results. In the experiment, 204 participants from the United States (Hispanic participants only), Russia, and the Republic of Korea were interviewed in their native language by a native‐speaking interviewer or by a British interviewer through an interpreter. Truth tellers discussed a trip that they had made during the last 12 months; liars fabricated a story about such a trip. The key dependent variables were the amount of information provided and the proportion of all statements that were complications. The proportion of complications distinguished truth tellers from liars better when answering unexpected than expected questions, but only in interpreter‐absent interviews. The number of details provided did not differ between truth tellers and liars or between interpreter‐absent and interpreter‐present interviews.     

Pub and community: The views of Birmingham untreated heavy drinkers

This paper reports the results of a qualitative analysis of semi‐structured interviews with 79 members of the Birmingham Untreated Heavy Drinkers Cohort. The cohort was recruited in 1997 when all participants were drinking 50 or more standard units of alcohol (men) or 35 or more units (women) most weeks. Present interviews were carried out as part of the fourth wave of interviews, held in 2003. The topic was the participants' places of drinking in the community and the functions those places served. The present analysis focused on the relationship between pubs and community. The strongest theme to emerge was that the pub provided for many participants a real sense of community in itself. It did so by enabling participants to meet with like‐minded others, in a setting distinct from home or work, where conversing and confiding could take place in a relaxed atmosphere, with a range of other activities and forms of social support available to many. At the same time, participants were discriminating about which pubs they used, and when, and with whom they chose to interact. There was less consensus about whether the pub served a wider function by contributing to a positive sense of community in the local neighbourhood. It is suggested that English pubs, at least in a large conurbation such as the West Midlands, are very varied, sometimes continuing to serve as ‘the local’ for a community, sometimes being part of a variety of drinking places which between them provide people with a diversity of social niches to meet their increasingly diverse choices and preferences, and sometimes reflecting and even contributing to local community disorganisation.

‘It's gotten a bit old,charity’: Young adults in New Zealand talk about poverty,charitable giving and aid appeals

An extensive body of literature exists on the phenomena of poverty, charitable giving and the effectiveness of aid appeals. To date psychological research has predominantly focused on individualistic models to explain people's understandings of poverty and their charitable giving practices. Based upon a social constructionist epistemology, this study investigates how understandings of aid appeals, poverty and charitable giving are discursively produced and constructed in relation to one another through an analysis of New Zealand young adults' talk about these issues. Data were collected from three focus group discussions among pre‐existing friendship groups comprising three male and nine female students aged between 18 and 25. A brief video clip of aid appeals was used to stimulate discussion on poverty and charitable giving. Analysis of these discussions revealed three discursive themes relating to the aid appeals: local versus international need, emotional arousal and insufficient information. Drawing upon these themes the participants constructed poverty as relative or extreme, and largely explained by educational deficits. They constructed charitable giving as solicited through aid appeals, as compromised through immunity to such appeals, and as diminished through positionings of self‐help and self‐responsibility. These discursive constructions were drawn on by participants to legitimate their own non‐donor position. Copyright © 2008 John Wiley & Sons, Ltd.     

Overriding auditory attentional capture

Attentional capture by color singletons during shape search can be eliminated when the target is not a feature singleton (Bacon & Egeth, 1994). This suggests that a "singleton detection" search strategy must be adopted for attentional capture to occur. Here we find similar effects on auditory attentional capture. Irrelevant high-intensity singletons interfered with an auditory search task when the target itself was also a feature singleton. However, singleton interference was eliminated when the target was not a singleton (i.e., when nontargets were made heterogeneous, or when more than one target sound was presented). These results suggest that auditory attentional capture depends on the observer's attentional set, as does visual attentional capture. The suggestion that hearing might act as an early warning system that would always be tuned to unexpected unique stimuli must therefore be modified to accommodate these strategy-dependent capture effects.     

Attentional capture in serial audiovisual search tasks

The phenomenon of attentional capture has typically been studied in spatial search tasks. Dalton and Lavie recently demonstrated that auditory attention can also be captured by a singleton item in a rapidly presented tone sequence. In the experiments reported here, we investigated whether these findings extend cross-modally to sequential search tasks using audiovisual stimuli. Participants searched a stream of centrally presented audiovisual stimuli for targets defined on a particular dimension (e.g., duration) in a particular modality. Task performance was compared in the presence versus absence of a unique singleton distractor. Irrelevant auditory singletons captured attention during visual search tasks, leading to interference when they coincided with distractors but to facilitation when they coincided with targets. These results demonstrate attentional capture by auditory singletons during nonspatial visual search.     

Nonconscious relationship reactance: When significant others prime opposing goals

Individuals nonconsciously and unintentionally pursue goals they associate with relationship partners ( [Fitzsimons and Bargh, 2003] and [Shah, 2003]). Here, we demonstrate conditions under which individuals nonconsciously and unintentionally reject goals they associate with relationship partners and instead pursue opposing goals. In Experiment 1, participants were subliminally primed with the name of a controlling significant other who had a particular goal for them. Without awareness or intent, participants pursued a goal that directly opposed their significant other’s wishes. In Experiment 2, chronic reactance was shown to moderate this effect: Low-reactant individuals adopted a subliminally primed significant other’s goal, whereas high-reactant individuals pursued an opposing goal. This research suggests that in response to controlling significant others and among chronically reactant individuals, the nonconscious activation of relational representations can automatically elicit oppositional goal pursuits, even when pursuit of an oppositional goal results in a personally suboptimal outcome.     

Family/media approach to HIV prevention: results with a home-based, parent-teen video program.

We describe the first study with a home-based HIV prevention video program for parents and young teenagers. The objectives of the program are to inform parents and teenagers about the causes and prevention of HIV infection and other sexually transmitted diseases, to increase family problem-solving skills, and to increase teen problem-solving and assertiveness skills. The objectives pertain to the goals of increasing skills needed to help teenagers avoid or manage high-risk behaviors and situations. Forty-five families with at least one 12- to 14-year-old were randomly assigned to either experimental (receive video program) or control (no video) conditions in a pretest-posttest design. After 6 months (Follow-Up 1), the experimental and control families were reassessed. The control families next received the video program, and the control families were assessed again (Follow-Up 2). The results indicate increases in parent and teen knowledge and skills only with video viewing. Approaches to improving the video program, particularly with teenagers, are discussed.     

Perceptual load does not modulate auditory distractor processing

In vision, it is well established that the perceptual load of a relevant task determines the extent to which irrelevant distractors are processed. Much less research has addressed the effects of perceptual load within hearing. Here, we provide an extensive test using two different perceptual load manipulations, measuring distractor processing through response competition and awareness report. Across four experiments, we consistently failed to find support for the role of perceptual load in auditory selective attention. We therefore propose that the auditory system – although able to selectively focus processing on a relevant stream of sounds – is likely to have surplus capacity to process auditory information from other streams, regardless of the perceptual load in the attended stream. This accords well with the notion of the auditory modality acting as an ‘early-warning’ system as detection of changes in the auditory scene is crucial even when the perceptual demands of the relevant task are high.
