SINGH AND GISLI H. GUDJONSSON* This study investigates some of the hypotheses generated by the Gudjonsson and Clark model of interrogative suggestibility. The subjects were 40 adolescent boys (11-16 years), who completed the Gudjonsson Suggestibility Scale and instruments measuring intellectual skills, memory, field-dependence, hostility, and attitudes towards persons in authority. Suggestibility correlated negatively with I.Q. and memory capacity, and positively with field-dependence. INTRODUCTION Interrogative suggestibility is a special type of suggestibility which bears little resemblance to the traditional type of suggestibility associated with hypnosis (Gudjonsson, 1987~). It is best construed as the tendency of an individual’s account of events to be altered by misleading information and inter-personal pressure within interviews (Gudjonsson 1983; 1984). In order to measure objectively interrogative suggestibility, Gudjonsson (1984) constructed a special scale, known as the Gudjonsson Suggestibility Scale (GSS 1). He subsequently developed a parallel form for research and clinical purposes, which is known as the GSS 2, because it enables subjects to be tested on more than one occasion (Gudjonsson, 19876). The two subscales of the GSS 1 and GSS 2, known as “ Yield” and “ Shift” , are highly correlated (Gudjonsson, 19873). Whereas “Yield” measures the extent to which subjects give in to leading questions, “ Shift” refers the tendency to change one’s answers after being given negative feedback. The GSS 1 has been extensively researched and validated with differ- ent adult populations (see Gudjonsson, 1992, for an extensive review), but the work carried out on adolescents is very limited.
