Psychological aspects of risk appraisal in asphyxiation accidents: a review of the factors influencing children's perception and behaviour.

Psychological aspects determining children's behaviour in response to asphyxiation risk due to ingestion of foreign matter have been rarely and non-systematically examined in the literature. Aim of this report is to highlight--through a review of the most significant psychological research in the literature--which factors influence the behaviour, perception and assessments of children 0 to 14 years of age, in a risk situation. In particular, attention is focused on the direct experience of a child at risk, assuming that this experience can play a significant role in future dangerous situations. Outcomes of studies taken into consideration have highlighted the influence of age, sex, socio-economic status, parents' role, peer group, personal traits, television and personal experience. The latter refutes the initial hypotheses, showing an unexpected and clearly negative effect on future evaluation and behaviour in response to similar contexts of asphyxiation risk. The implications for research on asphyxiation due to ingestion of foreign matter are examined.
