College students' eyewitness accuracy and suggestibility were assessed with two measures of suggestibility: (1) the non-forensic version of the Gudjonsson Suggestibility Scale [GSS 2; Gudjonsson, G. H. (1987). A parallel form of the Gudjonsson Suggestibility Scale. British Journal of Clinical Psychology, 27, 185–187; Gudjonsson, G. H. (1997). The Gudjonsson suggestibility scales manual. East Sussex, UK: Psychology Press.] in which participants hear a story and are then asked leading and suggestive questions and (2) a Standard Misinformation Paradigm in which participants experience an event, later receive misleading information regarding that event, and are then tested for their memory of the original event. The students also completed two personality inventories [NEO PI-R, Costa, P. T., & McCrae, R. R. (1992). Revised NEO Personality Inventory (NEO-PI R) and NEO Five Factor Inventory (NEO-FFI). Odessa, Florida: Psychological Assessment Inventories.; Multidimensional Personality Questionnaire (MPQ); Tellegen, A. (1982). Brief manual for the differential personality questionnaire. Unpublished manuscript, University of Minnesota, Department of Psychology, Minneapolis.], and four measures of perceived control. Findings on both suggestibility measures indicated that adults who were more suggestible had poorer recall of the original event. In addition, suggestibility on the GSS 2 was predicted by the perceived control dimensions of memory efficacy and locus of control, by facets on the extraversion and conscientiousness domains of the NEO PI-R, and by the traditionalism scale of the MPQ. In contrast, suggestibility on the Misinformation Paradigm was associated with facets on the openness to experience and agreeableness domains of the NEO PI-R. The results are discussed in terms of the multidimensionality of eyewitness suggestibility. |
