Age trends in eye-witness suggestibility and compliance

Abstract

This paper addresses two issues: whether there is a developmental trend in suggestibility to misleading post-event information, and whether suggestibility can be reduced by use of part of the cognitive interview. Twenty participants from each of three age groups (four-to-five year olds, eight-to-nine year olds and adults) watched a filmed event, and half of the participants in each age group were subsequently asked to recall everything they had seen using a method derived from the cognitive interview procedure. Following this, all participants were asked questions about the filmed event, some of which incorporated misleading information. Twenty four hours later the witnesses were interviewed again, this time critical questions were included about the truth of the presuppositions introduced in the initial questionnaire. It was found that although the eight-to-nine year olds were more suggestible than adults, the apparent greater suggestibility of very young children (four-to-five years) could potentially be explained in terms of heightened compliance to the perceived demands of the interviewer. The 'be complete' part of the cognitive interview only produced an improvement in performance for the eight-to-nine year olds.     

Memory conformity and suggestibility

Abstract

The present study examined whether the degree to which participants engage in memory conformity, which occurs when a person alters their memory report of an event to be consistent with another person, can be predicted by their levels of interrogative suggestibility (IS), which is the degree to which people are susceptible to altering their memory reports during questioning. Memory conformity was introduced by having participant and confederate pairs study words and then complete a social recognition test where they took turns to make judgements to the same items. When the participants responded after the confederate, they tended to conform to confederate's judgements regardless of whether the confederate had made a correct or incorrect response. IS was measured using the Gudjonsson Suggestibility Scale 2. This scale allows separate measures of Yield, which is a measure of how susceptible people are to altering their memory reports of events as a result of leading questions, and Shift, which is a measure of how susceptible people are to changing responses to questions when placed under pressure to do so. Only Yield was a significant predictor of memory conformity.     

讯问客体语言的听解

讯问人员对犯罪嫌疑人语言的听解有着重要的作用。讯问时,讯问人员要认真听辨犯罪嫌疑人的供述,细致地识别其有声语言、类语言和无声语言。     

讯问活动的思维形式——侦查讯问中的“问题”研究

讯问是以问答形式进行的侦查活动。问题负载着讯问信息，沟通讯问双方的思维，引领着讯问活动的方向。根据问题的逻辑重点可以将其分为判断型问题（包括是非式、选择式、填充式）、说明型问题、论证型问题三类。侦查讯问中运用问题暗示的原则是：问题暗示只能用于帮助犯罪嫌疑人形成供述动机，而在犯罪的时间、地点、工具等具体情节上禁止暗示；为了避免不良暗示，侦查人员在讯问犯罪情节时，应尽量使用填充或说明型问题，少用是非式和选择式问题。     

Is There Touch in the Game of Twister®? The Effects of Innocuous Touch and Suggestive Questions on Children's Eyewitness Memory

Preschool children (ages 48–70 months, N = 48) experienced 2 to-be-remembered events (i.e., the games Twister^® and Shapes) that included either innocuous bodily touch or no touch. Participants were interviewed 7 days later and asked direct (“Did Amy kiss you?”) or suggestive “tag” questions (“Amy kissed you, didn't she?”) equated for content. Results indicated that children who were innocuously touched were no more likely to falsely assent to “abuse-related” touch questions (e.g., “Amy touched your bottom, didn't she?”) than were children who were not touched. However, children who were asked tag questions responded at chance levels, thereby making high errors of commission in response to abuse-touch questions relative to their no-tag counterparts who responded to “abuse questions” accurately 93% of the time. Children who were asked tag questions assented at a higher rate to general forensic questions (“Amy took your picture, didn't she?”) than did children asked direct questions, and children assented at higher rates to “abuse-touch” questions than to general forensic questions. Results are discussed in terms of prior research on interviewing techniques and adult influence on children's testimony.     

A face in the crowd: The influences of familiarity and delay on preschoolers’ recognition

Abstract

Preschoolers’ abilities to recognize former caregivers were examined. Participants were 35 children from three preschool classes. Caregivers volunteered in the classes over a 7-week period. At an initial assessment, children were asked to select former caregivers from a line-up of five photographs, and to rank-order the caregivers by personal preference. Recognition was assessed again after 3 months. Although older toddlers performed at chance levels, clear age-related increases in recognition performance were observed, with older preschoolers recognizing 86% of the volunteers at time 2. Younger children responded less consistently over time than older children. Preference for individual caregivers affected recognition performance among younger, but not older, preschoolers. Implications for children's eyewitness testimony are considered.     

犯罪嫌疑人虚假供述的心理原因及其讯问策略

在实际讯问工作中,保持沉默和作虚假供述多被视为是拒供的表现,但二者在表现形态和心理原因上却存在着许多差别。通过对讯问中被讯问人各种不同于虚假供述的表现形态及其心理原因的分析和相应讯问策略的研究,可以进一步探讨讯问中达到获取犯罪嫌疑人真实供述这一最终目的的方法和途径。     

The Portuguese adaptation of the Gudjonsson Suggestibility Scale (GSS1) in a sample of inmates

This paper comprises two studies which address the validity of the Portuguese adaptation of the Gudjonsson Suggestibility Scale, GSS1. In study 1, the means and standard deviations for the suggestibility results of a sample of Portuguese inmates (N = 40, M_age = 37.5 years, SD = 8.1) were compared to those of a sample of Icelandic inmates (Gudjonsson, 1997; Gudjonsson & Sigurdsson, 1996). Portuguese inmates' results were in line with the original results. In study 2, the means and standard deviations for the suggestibility results of the sample of Portuguese inmates were compared to those of a general Portuguese population sample (N = 57, M_age = 36.1 years, SD = 12.7). The forensic sample obtained significantly higher scores in suggestibility measures than the general population sample. ANOVA confirmed that the increased suggestibility in the inmates sample was due to the limited memory capacity of this latter group. Given that the results of both studies 1 and 2 are in keeping with the author's original results (Gudjonsson, 1997), this may be regarded as a confirmation of the validity of the Portuguese GSS1.     

<Emphasis Type="Italic">Miranda</Emphasis> Comprehension in Adults with Mental Retardation and the Effects of Feedback Style on Suggestibility

Interrogations present several major challenges to persons with mental retardation (MR). Sixty adults with mild MR completed measures of Miranda comprehension and tendency to yield to leading questions. In addition, suggestibility was assessed based on whether participants revised answers to questions in response to unfriendly, friendly, or neutral feedback to original responses. Furthermore, we examined how expressed confidence in answers to repeated questions varied with the type of feedback received. Results revealed that participants demonstrated marked difficulties understanding their Miranda rights and greater likelihood of changing answers to questions for which they received friendly feedback than for questions for which they received unfriendly or neutral feedback. Most participants who received positive reinforcement for their answers on a second trial expressed confidence about improvement from trial 1 to trial 2, although accuracy did not improve. Implications of these results are reviewed.
