Order Effects of Ballot Position without Information-Induced Confirmatory Bias

Candidate list positions have been shown to influence decision making when voters have limited candidate information (e.g. Miller and Krosnick, 1998; Brockington, 2003). Here, a primacy advantage is observed due to a greater number of positive arguments generated for early list candidates (Krosnick, 1991). The present study examined list position effects when an absence of information precludes such a confirmatory bias heuristic. We report the first large scale low-information experimental election where candidate position is fully counterbalanced. Seven hundred and twenty participants voted in a mock election where the position of 6 fictitious and meaningless parties was counterbalanced across the electorate. Analysis by position revealed that significantly fewer votes were allocated to the terminal parties (Experiment 1). In addition, Experiment 1 reported preliminary evidence of an alphabetical bias (consistent with Bagley, 1966). However, this positional bias was not present in a methodological replication using six genuine UK political parties (Experiment 2). This suggests that in situations of pure guessing, the heuristic shifts from the primacy benefiting confirmatory bias to an alternative heuristic that prejudices the first and last parties. These findings suggest that whilst the UK general electoral process may be largely immune to positional prejudice, English local elections (in which there can be multiple candidates from the same party) and multiple preference ranking systems (Scottish Local Government and London Mayoral Elections) could be susceptible to both positional and alphabetical biases

Forming Judgments of Attitude Certainty, Intensity, and Importance: The Role of Subjective Experiences

Two studies examined the impact of subjective experiences on reports of attitude certainty, intensity, and importance. In Study 1, participants with moderate or extreme attitudes toward doctor-assisted suicide generated three (easy) or seven (hard) arguments that either supported or countered their opinion toward the issue prior to indicating the strength of their attitude. Participants with moderate attitudes rated their opinions as more intense, personally important, and held with greater certainty when they had generated either a small number of supporting arguments or a large number of opposing arguments. Ratings provided by individuals with extreme attitudes were unaffected by the argument generation task. In Study 2, the impact of ease of recall on strength-related judgments was eliminated when it was rendered nondiagnostic by a misattribution manipulation. Implications of these findings for attitude strength and other judgmental phenomena are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68385/2/10.1177_0146167299025007001.pd

Testing message framing to increase physical activity among British South Asians

Objective: British South Asians (BSAs) experience a higher incidence of coronary heart disease (CHD) which is not declining in line with the UK national average. Low physical activity levels are likely to contribute to this elevated risk. This study investigated the effectiveness of message framing, cultural sensitivity and their interaction on promoting physical activity among BSAs. Design: One hundred and seventy-nine participants (70 males and 109 females) were randomly allocated to watch one of four films in a 2 (loss vs. gain) × 2 (culturally sensitive vs. non-culturally sensitive) design. Main outcome measures: Measures of self-reported physical activity and behavioural intention were completed at baseline and two-month follow-up. Results: The analysis revealed no main effects for message framing, cultural sensitivity or for the interaction between these factors for self-reported physical activity and behavioural intention. Conclusions: Healthy BSAs appear not to respond to health promotion messages which have been manipulated by message framing or cultural sensitivity. Possible explanations are that despite an increased risk of developing CHD, healthy BSAs may be unwilling to engage in immediate action for a potential future health problem and cultural sensitivity may be irrelevant to a ‘Westernised’ sample. Nevertheless, future research ought to investigate variations of the current intervention by using a larger sample size, targeting a more sedentary population, varying the length and exposure to the intervention in less assimilated groups, clinically symptomatic populations or those at high risk of CHD

The Aversion to Tampering with Nature (ATN) Scale: Individual Differences in (Dis)comfort with Altering the Natural World

People differ in their comfort with tampering with the natural world. Although some see altering nature as a sign of human progress, others see it as dangerous or hubristic. Across four studies, we investigate discomfort with tampering with the natural world. To do so, we develop the Aversion to Tampering with Nature (ATN) Scale, a short scale that is the first to directly measure this discomfort. We identify six activities that people believe tamper with nature (geoengineering, genetically modified organisms, pesticides, cloning, gene therapy, and nanoparticles) and show that ATN scores are associated with opposition to these activities. Furthermore, the ATN Scale predicts actual behavior: donations to an antiâ tampering cause. We demonstrate that ATN is related to previously identified constructs including trust in technology, naturalness bias, purity values, disgust sensitivity, aversion to playing God, and environmental beliefs and values. By illuminating who is concerned about tampering with nature and what predicts these beliefs, the ATN Scale provides opportunities to better understand public opposition to technological innovations, consumer preferences for â naturalâ products, and strategies for science communication.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154364/1/risa13414_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154364/2/risa13414.pd

A functional-cognitive framework for attitude research

In attitude research, behaviours are often used as proxies for attitudes and attitudinal processes. This practice is problematic because it conflates the behaviours that need to be explained (explanandum) with the mental constructs that are used to explain these behaviours (explanans). In the current chapter we propose a meta-theoretical framework that resolves this problem by distinguishing between two levels of analysis. According to the proposed framework, attitude research can be conceptualised as the scientific study of evaluation. Evaluation is defined not in terms of mental constructs but in terms of elements in the environment, more specifically, as the effect of stimuli on evaluative responses. From this perspective, attitude research provides answers to two questions: (1) Which elements in the environment moderate evaluation? (2) What mental processes and representations mediate evaluation? Research on the first question provides explanations of evaluative responses in terms of elements in the environment (functional level of analysis); research on the second question offers explanations of evaluation in terms of mental processes and representations (cognitive level of analysis). These two levels of analysis are mutually supportive, in that better explanations at one level lead to better explanations at the other level. However, their mutually supportive relation requires a clear distinction between the concepts of their explanans and explanandum, which are conflated if behaviours are treated as proxies for mental constructs. The value of this functional-cognitive framework is illustrated by applying it to four central questions of attitude research

A proposed method to investigate reliability throughout a questionnaire

<p>Abstract</p> <p>Background</p> <p>Questionnaires are used extensively in medical and health care research and depend on validity and reliability. However, participants may differ in interest and awareness throughout long questionnaires, which can affect reliability of their answers. A method is proposed for "screening" of systematic change in random error, which could assess changed reliability of answers.</p> <p>Methods</p> <p>A simulation study was conducted to explore whether systematic change in reliability, expressed as changed random error, could be assessed using unsupervised classification of subjects by cluster analysis (CA) and estimation of intraclass correlation coefficient (ICC). The method was also applied on a clinical dataset from 753 cardiac patients using the Jalowiec Coping Scale.</p> <p>Results</p> <p>The simulation study showed a relationship between the systematic change in random error throughout a questionnaire and the slope between the estimated ICC for subjects classified by CA and successive items in a questionnaire. This slope was proposed as an awareness measure - to assessing if respondents provide only a random answer or one based on a substantial cognitive effort. Scales from different factor structures of Jalowiec Coping Scale had different effect on this awareness measure.</p> <p>Conclusions</p> <p>Even though assumptions in the simulation study might be limited compared to real datasets, the approach is promising for assessing systematic change in reliability throughout long questionnaires. Results from a clinical dataset indicated that the awareness measure differed between scales.</p

Provision of relapse prevention interventions in UK NHS Stop Smoking Services: a survey

Background UK NHS Stop Smoking Services provide cost effective smoking cessation interventions but, as yet, there has been no assessment of their provision of relapse prevention interventions. Methods Electronic questionnaire survey of 185 UK Stop Smoking Services Managers. Results Ninety six Stop Smoking Service managers returned completed questionnaires (52% response rate). Of these, 58.3% (n = 56) ran NHS Stop Smoking Services which provided relapse prevention interventions for clients with the most commonly provided interventions being behavioural support: telephone (77%), group (73%), and individual (54%). Just under half (48%, n = 27) offered nicotine replacement therapy (NRT), 21.4% (n = 12) bupropion; 19.6% (n = 11) varenicline. Over 80% of those providing relapse prevention interventions do so for over six months. Nearly two thirds of all respondents thought it was likely that they would either continue to provide or commence provision of relapse prevention interventions in their services. Of the remaining respondents, 66.7% (n = 22) believed that the government focus on four-week quit rates, and 42.9% (14 services) believed that inadequate funding for provision of relapse prevention interventions, were major barriers to introducing these interventions into routine care. Conclusions Just over half of UK managers of NHS Stop Smoking Services who responded to the questionnaire reported that, in their services, relapse prevention interventions were currently provided for clients, despite, at that time, there being a weak evidence base for their effectiveness. The most commonly provided relapse prevention interventions were those for which there was least evidence. If these interventions are found to be effective, barriers would need to be removed before they would become part of routine care
