Composition and safety evaluation of tea from New Zealand kawakawa (Piper excelsum)
Effects of alternative label formats on choice of high- and low-sodium products in a New Zealand population sample
Objective Dietary sodium reduction is a cost-effective public health intervention to reduce chronic disease. In response to calls for further research into front-of-pack labelling systems, we examined how alternative sodium nutrition label formats and nutrition claims influenced consumers’ choice behaviour and whether consumers with or without a diagnosis of hypertension differed in their choice patterns. Design An anonymous online experiment in …
Reactions to information about genetic engineering
There is a need to develop effective communication strategies with the public about the risks and benefits of applied genetic engineering. The Elaboration Likelihood Model was used to systematically investigate the impact of source factors (trust) and the perceived personal relevance of information, including the persuasiveness of the information, on attitudes towards genetic engineering, and whether these factors resulted in more thoughts about …
Objection’ mapping in determining group and individual concerns regarding genetic engineering
What Determines Trust in Information About Food‐Related Risks? Underlying Psychological Constructs
Trust in risk information about food related-hazards may be an important determinant of public reactions to risk information. One of the central questions addressed by the risk communication literature is why some individuals and organizations are trusted as sources of risk information and others are not. Industry and government often lack public trust, whereas other sources (for example, consumer organizations, the quality media, medical doctors…
Acute Effects on Mood and Cognitive Performance of Breakfasts Differing in Fat and Carbohydrate Content
Effect of Effort on Meal Selection and Meal Acceptability in a Student Cafeteria
Consumer acquisition of commercial and nutrition information in food choice
An investigation into the relationship between perceived control, attitude variability and the consumption of two common foods
The study reported here takes its lead from the literatures which emphasize the importance of attitude variability and the role of perceived control over action. Within‐person variability and perceptions of control are investigated in the context of people's attitudes towards the consumption of two common foods. The role of attitude ambivalence is also examined. The findings indicate that higher attitude variability is associated with weaker rela…
Expectancy‐value models of attitudes
Concern has been expressed in the literature regarding the method of scoring ‘beliefs’ within expectancy‐value models of attitudes. This paper reviews the major issues and focuses upon some hitherto largely neglected problems with scoring methods. Empirical findings from a series of studies concerned with ‘the theory of reasoned action’ are examined: with a multiplicative Combination of beliefs and evaluations, it is found that bipolar scoring of…
