The effects of anxious mood induction on suggestibility to misleading post‐event information

Abstract

AbstractLittle research has been carried out into the effects of anxious mood at the time of either the encoding of misleading post‐event information or the time of its possible retrieval, on subsequent suggestibility. Participants comprised 160 first‐year undergraduates. Using a standard suggestibility paradigm, half of all participants were exposed to misleading information while half were non‐misinformed controls. In addition there were four state anxiety conditions, dependent on the timing of the anxious mood induction: at the time of encoding misleading information; at retrieval only; at both encoding and retrieval; or at neither encoding nor retrieval (controls). Results showed memory accuracy for non‐suggestible items was unaffected by the anxious mood induction. With respect to suggestibility, there was a strong effect of misleading information. In addition, within the misinformed group, all three groups who experienced the anxious mood induction were significantly less suggestible than controls. These findings are discussed both in terms of theories of anxiety and cognition and the applied implications for the increasing use by the police of video‐recorded witness interviews.
