Genes, Autism and Psychological Spectrum Disorders
Patrick Walsh using the Spectrum of Opinion School Resource Pack to teach an A-level Psychology class at Robert Napier School
Spectrum of Opinion: Genes, Autism and Psychological Spectrum Disorders is a Progress Educational Trust (PET) project devised and overseen by PET Communications Officer Sandy Starr, and supported by the Wellcome Trust. The project was originally conceived as a response to autism expert Simon Baron-Cohen's call for an informed public debate about developments in genetics and our understanding of autism, following a media furore in 2009 about the prospect of genetic testing for autism. This episode highlighted shortcomings not only in public and media understanding of the relationship of genetics to psychology, but also in the divergent interpretations of this relationship promulgated by experts in different fields.
The three principal objectives of the Spectrum of Opinion project are:
The five principal outcomes of the Spectrum of Opinion project have been:
PET believes that the spectrum, and the relationship between genes and psychology that it hinges upon, are ideal subjects for public debate because they exemplify many of the challenges that characterise modern biomedicine and the public's understanding of it. Most notably, they exemplify the tension between different approaches to diagnosis, such as phenomenology and aetiology.
Initially, diagnostic categories tend to be constructed from prognosis and clinical descriptions of a disorder's presenting features. Subsequently, diagnostic categories tend to be constructed from an improved understanding of a disorder's biomedical causes. Categories arrived at via these different routes may coincide, but when they do not, then this may prompt a revision of the original category.
This potential disparity between diagnostic approaches is especially marked in the case of genetics and psychology, and may be further complicated by a number of other factors. The burgeoning field of epigenetics studies the biochemical mechanisms whereby gene expression may be selectively silenced in different tissues of the body and at different points during an individual's development, complicating our understanding of heritability. Then there are the many non-biomedical factors that can contribute to a spectrum of behaviours and impairments, and are the province of disciplines such as sociology.
The School Resource Pack created by PET as part of the Spectrum of Opinion project has been piloted at Robert Napier School in Gillingham, and PET has now made the pack freely available for anyone to read and use. It can be downloaded as a .pdf document (605KB), or alternatively is available in an online version.
We are keen to hear from anyone with feedback or ideas about the pack and its use, and we are especially keen to hear from anyone interested in helping PET to secure funding to develop the pack further. Please contact Sandy Starr at
