    Ethical Concerns and Risk Perceptions Associated with Different Applications of Genetic Engineering: Interrelationships with the Perceived Need for Regulation of the Technology. [REVIEW]Lynn J. Frewer & Richard Shepherd - 1995 - Agriculture and Human Values 12 (1):48-57.
    The development of genetic engineering and its plausible consequences raises a level of controversy that can be identified at the level of public rather than scientific debate. Opposition to genetic engineering may manifest itself in rejection of the technology overall, or rejection of specific aspects of the technology, where public attitudes may be defined by a complex set of perceptions incorporating risk, benefit, control, and ethical concerns.One hundred and seventy six members of the public responded to questionnaires about genetic engineering (...)

    The Role of Moral Judgments Within Expectancy-Value-Based Attitude-Behavior Models.Paul Sparks & Richard Shepherd - 2002 - Ethics and Behavior 12 (4):299 – 321.
    Rational choice models are characterized by the image of the self-interested Homo economicus. The role of moral concerns, which may involve a concern for others' welfare in people's judgments and choices, questions the descriptive validity of such models. Increasing evidence of a role for perceived moral obligation within the expectancy-value-based theory of reasoned action and the theory of planned behavior indicates the importance of moral-normative influences in social behavior. In 2 studies, the influence of moral judgments on attitudes toward food (...)

    Gene Technology, Food Production, and Public Opinion: A UK Study. [REVIEW]Paul Sparks, Richard Shepherd & Lynn J. Frewer - 1994 - Agriculture and Human Values 11 (1):19-28.
    In this paper, dimensions of the debate surrounding the application of gene technology to food production are discussed and a study assessing perceptions of the technology among a sample of the UK public (n = 1499) is reported. The general picture that emerges from the study is one of people expressing low familiarity with the technology, with more people associating it with high risks than with low risks, and more people expecting it to provide low benefits than high benefits. Attitudes (...)

    The Influence of Initial Attitudes on Responses to Communication About Genetic Engineering in Food Production.Lynn J. Frewer, Chaya Howard & Richard Shepherd - 1998 - Agriculture and Human Values 15 (1):15-30.
    Source credibility has been thought to bean important determinant of peoples‘ reactions toinformation about technology. There has also been muchdebate about the need to communicate effectively withthe public about genetic engineering, particularlywithin the context of food production. Questionnaireswere used to investigate the impact of sourcecredibility, admission of risk uncertainty, andinitial attitude towards genetic engineering onattitudes of respondents after information provision.120 respondents with positive attitudes towardsgenetic engineering in food production were providedwith persuasive information about the technology,where both source attribution and admission (...)
