Effects of active information processing on the understanding of risk information

Two experiments investigated effects of active processing of risk information on participants' understanding and judgments. It was hypothesized that more active processing would lead to better understanding and differences in affective judgments (e.g. increased satisfaction and reduced perceived risk to health). In both experiments participants were given a written scenario about their being prescribed a fictitious medication. This medication was said to cause side effects in 2% of people who took it. Before answering a series of written questions, participants in the active conditions of both experiments were asked to carry out a reflective task (portraying the size of risk on a bar chart in Experiment 1 and answering a reflective question in Experiment 2). The results showed that active participants rated the likelihood of experiencing possible side effects significantly lower than passive participants (Experiment 1), and that active participants were significantly more satisfied with the information and judged perceived risk to health from taking the medication significantly lower than passive participants (Experiment 2). In both experiments, active participants were significantly more correct in their probability and frequency estimates. The studies demonstrate that active processing of risk information leads to improved understanding of the information given. This has important implications for risk communication. In the context of health, better understanding should lead to improved decision-making and health outcomes. Copyright (C) 2004 John Wiley Sons, Ltd.

Training conditional and cumulative risk judgements: the role of frequencies, problem-structure and Einstellung

Two experiments implement and evaluate a training scheme for learning to apply frequency formats to probability judgements couched in terms of percentages. Results indicate that both conditional and cumulative probability judgements can be improved in this manner, however the scheme is insufficient to promote any deeper understanding of the problem structure. In both experiments, training on one problem type only (either conditional or cumulative risk judgements) resulted in an inappropriate transfer of a learned method at test. The obstacles facing a frequency-based training programme for teaching appropriate use of probability data are discussed. Copyright (c) 2006 John Wiley & Sons, Ltd.

Drivers' ratings of different components of their own driving skill: a greater illusion of superiority for skills that relate to accident involvement

Different components of driving skill relate to accident involvement in different ways. For instance, while hazard-perception skill has been found to predict accident involvement, vehicle-control skill has not. We found that drivers rated themselves superior to both their peers and the average driver on 18 components of driving skill (N = 181 respondents). These biases were greater for hazard-perception skills than for either vehicle-control skills or driving skill in general. Also, ratings of hazard-perception skill related to self-perceived safety after overall skill was controlled for. We suggest that although drivers appear to appreciate the role of hazard perception in safe driving, any safety benefit to be derived from this appreciation may be undermined by drivers' inflated opinions of their own hazard-perception skill. We also tested the relationship between illusory beliefs about driving skill and risk taking and looked at ways of manipulating drivers' illusory beliefs.

Reducing implicit prejudice by blurring intergroup boundaries

In two experiments we examined whether and when blurring intergroup boundaries reduces implicit prejudice. In Experiment 1 we observed that when participants first completed a task in which they generated characteristics that overlapped between an ingroup and an outgroup they showed less implicit bias as measured by an Implicit Association Test. In Experiment 2 we found that the effectiveness of blurring intergroup boundaries for reducing implicit bias was moderated by pretask levels of ingroup identification. We discuss these findings in the context of extending differentiation-based interventions for reducing explicit bias to the domain of implicit attitudes.

Implicit memory and consumer choice: the mediating role of brand familiarity

Two experiments investigated the influence of implicit memory on consumer choice for brands with varying levels of familiarity. Priming was measured using a consideration-choice task, developed by Coates, Butler and Berry (2004). Experiment 1 employed a coupon-rating task at encoding that required participants to meaningfully process individual brand names, to assess whether priming could affect participants' final (preferred) choices for familiar brands. Experiment 2 used this same method to assess the impact of implicit memory on consideration and choice for unknown and leader brands, presented in conjunction with familiar competitors. Significant priming was obtained in both experiments, and was shown to directly influence final choice in the case of familiar and highly familiar leader brands. Moreover, it was shown that a single prior exposure could lead participants to consider buying an unknown, and indeed fictitious, brand. Copyright (c) 2006 John Wiley & Sons, Ltd.

Implicit memory: a prime example for brand consideration and choice

Three experiments investigated the influence of implicit memory for familiar brand names on consumer choice. Priming was measured using modified preference judgment tasks that comprised both brand consideration and choice components. Experiment 1 used a 'complex choice task' where consideration and choice stages were characterized as acting in sequence. Experiment 2 explored a different formulation whereby consideration and choice were assumed to act in parallel, Both experiments demonstrated that priming had an influence on brand consideration but not on final or preferred choice. Finally, Experiment 3 replicated and extended these findings under more realistic conditions where participants actually received some of the products that they selected. Overall, the experiments suggested that for many decisions involving the consideration of familiar brands prior to choice, previous exposure to brand names can increase the likelihood that they will enter the consumers' consideration set. However, the advantage does not appear to extend to choice itself. Copyright (C) 2004 John Wiley Sons, Ltd.

Reverberant auditory environments: the effects of multiple echoes on distraction by 'irrelevant' speech

Two experiments examine the effect on an immediate recall test of simulating a reverberant auditory environment in which auditory distracters in the form of speech are played to the participants (the 'irrelevant sound effect'). An echo-intensive environment simulated by the addition of reverberation to the speech reduced the extent of 'changes in state' in the irrelevant speech stream by smoothing the profile of the waveform. In both experiments, the reverberant auditory environment produced significantly smaller irrelevant sound distraction effects than an echo-free environment. Results are interpreted in terms of changing-state hypothesis, which states that acoustic content of irrelevant sound, rather than phonology or semantics, determines the extent of the irrelevant sound effect (ISE).

Auditory distraction from low-intensity noise: a review of the consequences for learning and workplace environments

The 'irrelevant sound effect' in short-term memory is commonly believed to entail a number of direct consequences for cognitive performance in the office and other workplaces (e.g. S. P. Banbury, S. Tremblay, W. J. Macken, & D. M. Jones, 2001). It may also help to identify what types of sound are most suitable as auditory warning signals. However, the conclusions drawn are based primarily upon evidence from a single task (serial recall) and a single population (young adults). This evidence is reconsidered from the standpoint of different worker populations confronted with common workplace tasks and auditory environments. Recommendations are put forward for factors to be considered when assessing the impact of auditory distraction in the workplace. Copyright (c) 2005 John Wiley & Sons, Ltd.

When's your birthday? The self-reference effect in retrieval of dates

Material encoded with reference to the self is better remembered. One interpretation of this effect is that the self operates to organise retrieval of memories. We were motivated to find out whether this organisational principle extended to everyday information and for material not explicitly related to the self. Participants generated friends' birthdays from memory and then gave their own birthday. We found that participants were particularly likely to recall birthdays from on or around the date of their own birthday. Thus, memory for birthdays clusters around self-relevant information, even when there is no specific attempt to recall self-related material. Birthdays clustered somewhat around the time of testing, important dates in the calendar, and for a close other, but not to the extent of the participants' birthdays. We suggest this is a demonstration of the organisational structure of the self in memory. Copyright (C) 2010 John Wiley & Sons, Ltd.

Exploring homeless people’s use of outreach services: applying a social psychological perspective

A number of critiques have been published drawing attention to the gaps in research methods applied to issues surrounding homelessness and service utilisation in Britain. This paper discusses the use of social identity, a theory drawn from the field of applied social psychology, and synthesises it with the pathways model, thereby providing a framework to further explore service utilisation. The synthesised framework was used to predict the uptake of outreach services in a prospective study of 121 homeless people in a major UK city. In general, homeless people's use of intervention services was affected by the extent to which they identified with the support services themselves. The study demonstrates the central role of social identity in understanding service utilisation patterns, and shows the importance of applying fresh techniques to fine-tune our understanding of uptake in the long term.

Att skapa sammanhållning via ett systemutvecklingsprojekt : med inspiration av idrottspsykologi

Detta examensarbete har genomförts av två studenter vid Högskolan Dalarna i samarbete medIT-konsultbolaget Istone Concrevi. Edsbyverken, som är en möbeltillverkare baserad i Edsbyn,är kund hos Istone och har ett behov att öka sin leveranssäkerhet. Företaget upplever också attdet finns en bristande sammanhållning mellan de som arbetar administrativt och de som arbetarmed tillverkning i verksamheten. Edsbyverken hoppas att en ökad sammanhållning ska varabidragande till en bättre leveranssäkerhet. Sammanhållning är ett begrepp som är vanligtförekommande inom idrott och lagsporter och förknippas ofta med framgång inom idrotten.Forskningsstrategin som används i studien är design and creation som fokuserar på att skapa nyaIT-produkter, artefakter. Denna studie har resulterat i en artefakt av typen instansiering i form aven applikation som utvecklats med hjälp av ett användarcentrerat och agilt arbetssätt. Syftet medstudien är att undersöka och testa hur teorier inom idrottspsykologi kan användas inom ettsystemutvecklingsprojekt med ändamål att få artefakten och utvecklingsprocessen att främjasammanhållning hos verksamheten. Datainsamlingsmetoder som använts i studien är intervjueroch enkäter. Intervjuerna har använts för att insamla bakgrundsinfo från verksamheten ochönskemål kring appen och enkäterna för feedback på appen samt för att utvärderasystemutvecklingens och appens påverkan på sammanhållningen.Resultaten från datainsamlingen är i många fall spretande med allt från positiva omdömen sommenar att sammanhållningen förbättrats, till negativa som menar att ingen inverkan skett. Vid ensammanvägning kan man dock se att majoriteten menar att detta forskningsprojekt inte lyckatsmed att förbättra sammanhållningen. En viss andel anställda vid Edsbyverken tror dock attsammanhållningen kan öka på längre sikt. Slutsatsen kring idrottspsykologi är att den vid enkoppling till systemutveckling har ett begränsat användningsområde och att många av de teoriersom förekommer om sammanhållning inte är användbara eller passande vidsystemutvecklingsarbete.

Dinâmicas sociais e estados de humor

O objetivo do estudo foi avaliar as relações das dinâmicas sociais (família, amigos e escola; i.e., três fatores sociais) sobre os estados de humor. A pesquisa foi realizada com uma equipe feminina de voleibol (14/15 anos). Aplicou-se o teste POMS (Profile of Mood States) para mensurar os estados de humor. Foi utilizada uma escala de 1 (muito mal) a 5 (muito bem) para que as atletas avaliassem cada um dos três fatores. Os resultados apontaram correlações significativas entre as escalas e os estados de humor; e diferenças significativas entre os níveis de intensidade apontados na escala dos três fatores e os estados de humor. Os resultados indicam clara interferência das dinâmicas sociais sobre os estados de humor, portanto, as interferências sociais não podem ser descartadas na preparação do atleta.
