Little consensus exists regarding how the details of truthful and false allegations of traumatic victimisation may change over short and long time intervals, yet this cue is utilised in the assessment of witness, victim and suspect credibility. The present study involved a narrative analysis of the details written within 147 sets of allegation statements across both short-term (~3 months) and long-term (~6 months) intervals. Overall results indicated that true allegations contained more consistent details, omissions and commissions, although the rates of change over time were variable. These changes appear to result from natural variations in memory and recall over time. However, direct contradictions (inconsistent details) were more prevalent in false allegations, and these claims were more stable over time, suggesting ‘script-like’ processing. These results have implications for our understanding of testimonial alterations and how determinations of veracity are influenced by statement details. Copyright © 2014 John Wiley & Sons, Ltd.

Purpose. Assessing the credibility of reports of sexual victimization - often in the absence of corroboration - presents a significant challenge for legal decision makers. This study examined the accuracy of observers in discriminating genuine and fabricated sexual assault allegations. Further, we examined whether individual differences and cue utilization strategies influenced deception detection accuracy.Methods. Observers (N= 119) evaluated eight (four truthful and four deceptive) written allegations of sexual assault (counterbalanced), and completed a Credibility Assessment Questionnaire (CAQ) and individual differences measures.Results. Results indicated that overall accuracy was below chance (M= 45.3%), and a truth bias was evidenced. Examining the Big Five personality traits, we found that openness to experience and neuroticism were positively associated with accuracy, whereas extraversion was negatively related to accuracy. Further, judgement confidence was negatively associated with accuracy.Conclusions. The present study offers insights into observers' perceptions of credibility regarding real-life sexual assault allegations. Implications for legal decision making are discussed. Language: en

Purpose. The process of catching liars is challenging, though evidence suggests that deception detection abilities are influenced by the characteristics of the judge. This study examined individual differences in emotional processing and levels of psychopathic traits on the ability to judge the veracity of written narratives varying in emotional valence. Methods. Undergraduate participants (N= 251) judged the veracity of 12 written narratives (truthful/deceptive) across three emotional categories: positive, negative, and neutral events. Levels of psychopathy were assessed to investigate its relation to accuracy and cue use. Results. Overall accuracy was close to chance, although participants were more accurate in determining the veracity of truthful relative to deceptive narratives. Accuracy was impaired for emotional (positive and negative) relative to neutral narratives. Psychopathy was not associated with levels of overall accuracy, but related to discriminative ability, and differential use of cues in decision making. Reported cue use also differed across emotional narrative conditions. Conclusions. We speculated that an emotive truth bias may have detracted judges from attending to valid cues that are indicative of the deceptive nature of stimuli because they were distracted by the emotional content of the report. Implications for deception detection in forensic settings are discussed.

SUMMARY The credibility of reports of victimization must be evaluated by police and adjudicators. The present prospective study investigated the features of truthful and fabricated narratives of trauma and their relative consistency over a 6-month period. Participants described both a genuine and fabricated traumatic experience on three occasions over the 6 months. The narrative features were coded at each phase and the stories’ consistency was examined at Times 2 and 3. We found that truthful trauma narratives contained more: details, contextual information, and emotional details, and were rated as more ‘plausible’, relative to fabricated traumas. The details of truthful narratives also were more factually consistent than fabricated narratives over the 6 month interval. This research offers basic information on the nature and consistency of traumatic memories, and potentially applicable information for discriminating true and false allegations.

This study examined the relative consistency and characteristics of memories for trauma and other non-traumatic emotional experiences over time. A community sample of 52 participants who reported a recent traumatic event were asked to recall both the traumatic and a positive emotional experience in two interviews separated by approximately three months (M = 105.39 days). The recollections were elicited with either a free narrative, cognitive interview, guided imagery, or written narrative approach. Results indicated that traumatic experiences were recalled more reliably over time than other emotional experiences. Traumatic memory imagery tended to persist in memory (with no apparent impairment), whereas features of positive memories were subject to considerable distortion, regardless of interview style. The findings contribute to the understanding of the impact of trauma on memory with the passage of time. Copyright © 2004 John Wiley & Sons, Ltd.
