Risk perception as a function of risk exposure amongst rock climbers

ObjectivesThe first objective was to examine the extent to which climbers' climbing safety perceived competence (CSPC) and perceived own absolute (POAR) and comparative (PCR) risk of getting seriously injured whilst climbing is related to risk exposure. The second objective was to examine which variables influence POAR and PCR.MethodTwo hundred and thirty-five climbers (M = 32, SD = 10.2 years of age) completed the following questionnaires: a CSPC scale specifically developed to assess perceived ability to practice climbing safely; indirect measures of PCR, consisting in the subtraction of the participants' assessment of their own risks from their assessment of other climbing referents' risks; and the Life Orientation Test-Revised, measuring dispositional optimism (DO). Participants were approached in their practices sites from Mediterranean regions, and were divided into groups based on their climbing practice's risk exposure; that is, high risk: traditional climbing (TRAD; n = 42); moderate risk: leading (LEAD; n = 89); and low risk: either top-roping (TOP; n = 51) or indoor bouldering (IND; n = 53).ResultsAnalyses of variance showed that TRAD expressed higher CSPC and higher POAR than the other groups. PCR also differed amongst the groups. More specifically, TRAD expressed comparative pessimism and LEAD expressed comparative optimism, as their POAR was, respectively, higher and lower than their perceived average climber's risk. TOP and IND perceived their own risk in a similar way to that of the average climber. Regression analyses showed that DO did not influence POAR or PCR. Past injury episode was positively related to POAR and negatively related to the propensity to express comparative optimism, though only amongst TRAD and LEAD.ConclusionsClimbers' risk perception accurately reflected their risk exposure. Climbers whose climbing modality involves higher risks acknowledged so when evaluating their own absolute and comparative risks of getting seriously injured whilst climbing.     

Text messaging, personality, and the social context

The purpose of this research was to undertake some analyses of how the language used in text messaging varies as a function of personality traits and the interpersonal context. After completing personality questionnaires, participants provided their most recent text messages and indicated their relationship with the message recipient on several dimensions. Correlations between Linguistic Inquiry and Word Count (LIWC) categories and personality traits and relationship status were examined. There were significant correlations between certain LIWC categories and extraversion (e.g., personal pronouns), neuroticism (e.g., negative emotion words) and agreeableness (e.g., positive emotion words), suggesting that personality traits are displayed in how one texts. One of the defining features of texting - linguistic alterations (e.g., abbreviations) - varied as a function of both personality traits and relationship status. Overall, the results provide a snapshot of what text messages look like, and how they reflect the texter’s personality and the interpersonal context.     

Social identity and the perception of history: cultural representations of Aotearoa/New Zealand

The context of intergroup relations in Aotearoa/New Zealand was investigated using perceptions of history by Maori (Polynesian‐descended) and Pakeha (European‐descended) samples from university and the general public. There was strong consensus that the Treaty of Waitangi was the most important event in New Zealand's history, but only Maori, the subordinate ethnic group, showed in‐group favouritism in their judgments regarding the Treaty. Pakeha, the dominant group, showed outgroup favouritism, and distanced themselves from past injustices using linguistic strategies. Maori students showed interest in their ethnic origins (ontogeny), rating the distant past and Polynesian history higher, and free‐recalling more events prior to European arrival than other groups; Maori in the general population shared a more similar perception of history to Pakeha. Both in‐group favouritism and ontogeny were found in sentence‐completion choices. Historical perceptions were strongly related to positions on current political issues. Results are related to social identity theory, social representations theory, and social dominance theory. Copyright © 1999 John Wiley & Sons, Ltd.     

Situation Awareness: Its proficiency amongst older and younger drivers,and its usefulness for perceiving hazards

The two studies reported here sought to measure and compare the Situation Awareness (SA) of younger and older driver groups whilst driving (Study 1), and watching video footage of actual car journeys (Study 2). In both studies this was achieved by recording a participant’s commentary on what s/he felt was of relevance to the driving task. The narratives produced were analysed by computer software that could abstract main concepts and calculate scores indicative of Situation Awareness. In Study 2, these scores were related to others for hazard perception proficiency (also derived from participant commentaries). It was found that the older drivers matched and often exceeded the younger drivers when their SA scores were compared individually, but not when assessed as a group. However, the younger drivers out-performed their older counterparts in hazard perception ability, and this was shown to be related to their Situation Awareness score. When the results from participants who undertook both studies were compared, it was found that Situation Awareness performance was significantly higher when commenting on video footage (Study 2) than whilst actually driving (Study 1).     

Risk perception in novice drivers: the relationship between questionnaire measures and response latency

The extent to which questionnaire based measures of driving risk, driving ability and accident likelihood are associated with response latency based measures obtained on a hazard perception test was examined. In Experiment 1 questionnaire evaluations of driving in general were obtained and correlated with hazard perception performance. In Experiment 2 questionnaire evaluations and hazard perception performance were obtained when drivers viewed the same driving scenes. In neither experiment did questionnaire responses correlate significantly with hazard perception performance. Additionally while in both experiments no difference in hazard perception performance arose between males and females, females rated driving as more risky and their ability to be lower than males. The results indicate independence between questionnaire and response latency measures of hazard perception. However the possibility that both approaches should be adopted within a single framework is raised.     

The relationship between cognitive function and hazard perception in younger drivers

Driving is a complex task; with research suggesting cognitive function plays a significant role in driver behaviour. Recent studies have investigated the role of cognitive function in younger drivers who are experiencing brain maturation and are over-represented in crash statistics. Emerging evidence suggests poor cognitive functioning is one explanation for this high crash risk. For younger drivers, the relationship between cognitive function and driving ability has been consistently shown for speeding and lane deviations. However, the driving skill most consistently linked to crash involvement is hazard perception, which is the ability to anticipate and respond to potentially dangerous traffic situations. The aim of this study was to investigate the cognitive correlates of hazard perception in younger drivers. Seventy-nine undergraduate students completed a hazard perception test and a battery of cognitive tests that have previously demonstrated a relationship with safe driving. The newly created hazard perception test measured accuracy of hazard identification, response times when anticipating the hazard, and response times when taking action to avoid the hazard. Hazard perception accuracy was significantly related to visuo-spatial skills, executive functioning and global cognitive status. Anticipation response times were significantly related to inhibitory control, with no significant relationship found between cognitive function and action response times. These findings are discussed in line with limitations in the study. Future research into the role of specific cognitive domains could lead to the enhancement of hazard perception testing for licensing with cognitive training and assessment, with the potential to reduce the crash risk of vulnerable younger drivers.     

Models and mosaics: Investigating cross-cultural differences in risk perception and risk preference

In this article, we describe a multistudy project designed to explain observed cross-national differences in risk taking between respondents from the People’s Republic of China and the United States. Using this example, we develop the following recommendations for cross-cultural investigations. First, like all psychological research, cross-cultural studies should be model based. Investigators should commit themselves to a model of the behavior under study that explicitly specifies possible causal constructs or variables hypothesized to influence the behavior, as well as the relationship between those variables, and allows for individual, group, or cultural differences in the value of these variables or in the relationship between them. This moves the focus from a simple demonstration of cross-national differences toward a prediction of the behavior, including its cross-national variation. Ideally, the causal construct hypothesized and shown to differ between cultures should be demonstrated to serve as a moderator or a mediator between culture and observed behavioral differences. Second, investigators should look for converging evidence for hypothesized cultural effects on behavior by looking at multiple dependent variables and using multiple methodological approaches. Thus, the data collection that will allow for the establishment of conclusive causal connections between a cultural variable and some target behavior can be compared with the creation of a mosaic.     

The development and validation of a hazard perception test for Thai drivers

Thailand is a developing country with a high traffic accident fatality rate. However, few attempts have been made to understand crash risks in Thai drivers from a psychological perspective. The purpose of the present study was to develop and validate a latency-based hazard perception test for Thai drivers. The initial test comprised our full item pool of 77 clips containing traffic conflicts captured on video from the driver’s perspective on Thai roads. We evaluated the validity of this test by examining whether performance differed as a function of driving experience in a sample of 135 Thai drivers. We found that experienced drivers (n = 87) performed significantly better than novice drivers (n = 48) after adjusting for individual differences in computer mouse skill, mirroring crash risk differences between these groups. The final 30-item version of the test, which comprised the best items from the initial test, yielded novice/experienced driver differences with or without adjusting for computer mouse skill. These results offer preliminary support for the validity of the latency-based test as a measure of hazard perception ability in Thai drivers.     

Individual differences in risk perception versus risk taking: handedness and interhemispheric interaction

Research indicates that right-hemisphere mechanisms are specifically sensitive to and averse to risk. Research also indicates that mixed degree of handedness is associated with increased access to right hemisphere processing. Accordingly, it was predicted that mixed-handers would exhibit greater risk aversion. Participants were presented with various risky activities and were asked to rate (i) the perceived risk, (ii) the perceived benefit, and (iii) their likelihood to engage in each activity. No handedness differences were found for any of these ratings. Regression analyses, however, indicated that the likelihood to engage in risky activities was predicted primarily by the perceived risks in mixed-handers and by the perceived benefits in strong-handers.     

Explaining contradictory relations between risk perception and risk taking

Different studies have documented opposite relations between perceived risk and behavior. The present study tested a theoretical explanation that reconciles these conflicting results. Adolescents (N= 596) completed alternative measures of risk perception that differed in cue specificity and response format. As predicted by fuzzy-trace theory, measures that emphasized verbatim retrieval and quantitative processing produced positive correlations between perceived risk and risky behavior; risk perceptions reflected the extent to which adolescents engaged in risky behavior. In contrast, measures that assessed global, gist-based judgments of risk produced negative correlations; higher risk perceptions were associated with less risk taking, a protective rather than reflective relation. Endorsement of simple values and principles provided the greatest protection against risk taking. Results support a dual-processes interpretation of the relation between risk perception and risk taking according to which observed relations depend on whether the cues in questions trigger verbatim or gist processing.     

Emotion and reason in everyday risk perception

Although research has documented the importance of emotion in risk perception, little is known about it in the context of everyday life. Using the Experience Sampling Method (ESM), 94 part‐time students were prompted at random—via cellular telephones—to report on mood state and three emotions and to assess risk on thirty occasions during their working hours. The emotions—valence, arousal, and dominance—were measured using self‐assessment manikins (SAMs) (Bradley & Lang, 1994). Hierarchical linear models (HLM) revealed that mood state and emotions explained significant variance in risk perception. In addition, valence and arousal accounted for variance over and above “reason” (measured by severity and possibility of risks). Six risks were re‐assessed in a post‐experimental session and found to be lower than their real‐time counterparts. The study demonstrates the feasibility and value of collecting representative samples of data with simple technology. Evidence is also provided to demonstrate the statistical consistency of the HLM estimates. Copyright © 2010 John Wiley & Sons, Ltd.     

Worry propensity and the perception of risk

This paper examines how the tendency to worry impacts risk estimation for an upcoming, stressful event. Students in a statistics class completed worry, anxiety, and subjective risk questionnaires on the first day of class. State-anxiety and subjective risk questionnaires were again administered immediately before their first examination. Subjects showed significant increases in anxiety and the perceived risk of poor academic performance in the class. Risk domains unrelated to the examination (e.g., physical threats) remained stable across measurement periods. Regression analysis was used to determine the independent contribution of worry propensity in predicting elevations in the perceived risk of poor academic performance. The analysis showed that worry propensity predicted subjective risk bias, even after variance attributable to current mood and trait anxiety had been removed. Results from a second series of regression equations suggested subjective risk biases partially mediated the relationship between worry propensity and current mood. These results are used to argue that the elevations in state anxiety observed when worriers are confronted with a stressful event are largely a function of risk inflation.     

Measuring perceived risk: Self-reported and actual hand positions of SUV and car drivers

This research examines the observed steering wheel hand positions and the reported steering wheel hand placements of a sample of Sports Utility Vehicle (SUV) and car drivers. Following the method of Walton and Thomas (Walton, D. & Thomas, J. A. (2005). Naturalistic observations of driver hand positions. Transportation Research Part F. Traffic Psychology and Behaviour, 8, 229–238), variation in hand position is found to be an effective, indirect measure of drivers’ perceived risk. As perceived risk increases, it is expected that drivers will be more likely to adopt a ‘10–2 o’clock’ hand placement to increase their control over the vehicle. Because they are a larger vehicle, SUVs are typically perceived by drivers as being safe, so it is also expected that SUV drivers would have a lower level of perceived risk, as evidenced by their hand positions. A questionnaire examining drivers’ hand placements confirmed that drivers do perceive that two hands on the top half of the steering wheel will give the most control over the vehicle, and also revealed that drivers overestimate their use of this hand position, when compared with actual observation. Observed hand positions reveal that SUV drivers are more likely to drive with one hand instead of two hands on the top half of the steering wheel, indicating a lower level of perceived risk.     

Environmental risk: perception and target with local versus global evaluation

This research addressed environmental risk perception depending on the target evaluated and on the category of hazard (technological and chemical hazards, climate change, loss of biodiversity). Correlations between environmental risk assessment and pro-environmental behavioural intentions were also tested. In a sample of 113 French adults, 15 different environmental risks were evaluated for four different risk targets (oneself, the inhabitants of the town, the inhabitants of the country, and humanity). As expected, environmental hazards were perceived as a greater risk for larger areas. Moreover, risks difficult to conceptualise, which contain both high uncertainty and long-term consequences (climate change, loss of biodiversity) are perceived as less risk to oneself and to the inhabitants of the town and the country of residence than more concrete and immediate risks (technological and chemical). Only the technological and chemical hazards significantly predict pro-environmental behavioural intentions.

Physician decision making and cardiac risk: effects of knowledge, risk perception, risk tolerance, and fuzzy processing

Despite training, professionals sometimes make serious errors in risky decision making. The authors investigated judgments and decisions for 9 hypothetical patients at 3 levels of cardiac risk, comparing student and physician groups varying in domain-specific knowledge. Decisions were examined regarding whether they deviated from guidelines, how risk perceptions and risk tolerances determined decisions, and how the latter differed for knowledge groups. More knowledgeable professionals were better at discriminating levels of risk according to external correspondence criteria but committed similar errors in disjunctive probability judgments, violating internal coherence criteria. Also, higher knowledge groups relied on fewer dimensions of information than did lower knowledge groups. Consistent with fuzzy-trace theory, experts achieved better discrimination by processing less information and made sharper all-or-none distinctions among decision categories.     

Avoidance motivation,risk perception and emotional processing

The present studies examined the moderating role of state motivation on the associations between trait avoidance motivation, risk perception and emotional processing. In Studies 1 and 2, avoidance or approach states were evoked in participants who then completed a risk perception task and a trait avoidance motivation measure. Both studies showed that trait avoidance only correlated with risk perceptions among individuals in approach state. In Study 3, emotional interpretation was measured. State and trait avoidance motivation did not interact in predicting emotional interpretation. The results showed that the effect of state motivation can explain the low correlations found between trait avoidance and risk perceptions, and suggested that the avoidance system may operate on an on–off principle rather than synergistically.

Selective review,optimism and HIV risk perception

Abstract

Research suggests that review of risk factors increases optimism about health. The present experimental study explored the effects of reviewing risk increasing and risk decreasing factors on HIV risk perception (own risk, others' risk, optimism), self efficacy and behavioural intentions. 164 heterosexual subjects completed a questionnaire concerning their beliefs about HTV and their sexual behaviour. Subjects were allocated to either the risk increasing condition (eg. since being sexually active how often have you asked your partners HIV status?), the risk decreasing condition (eg. since being sexually active how often have you tried to select your sexual partners carefully?), or a control group. The results suggest that review of risk decreasing factors increased optimism and that this change in optimism was related to an increase in perceived others' risk. The results are discussed in terms of theories of selective focus and egocentricism in risk perception and the implications for health promotion.
