Purpose. Deception detection research has mainly studied denials and distortionsgiven by students. This study examined true and false confessions as told by offenders.It was hypothesized that the statement analytic techniques Criteria-Based ContentAnalysis (CBCA) and Reality Monitoring (RM) would discriminate truths and lies.Methods. Truthful and deceptive confessions to crime were given by 30 offenders(both women and men) in a within-subject design. The participants were in prison at thetime of data collection, and told the truth about a crime they had committed and beensentenced for. In addition, they made up a lie about a different crime after a few minutesof preparation. The transcribed statements were scored for CBCA and RM criteria.Results. Results showed that neither total CBCA nor total RM scores differentiatedbetween lies and truths. Some individual CBCA criteria, however, showed differences:more self-deprecations and doubts about own testimony in the told lies, and more unexpectedcomplications in the truths.Conclusions. The results are discussed in relation to statement analysis of offenders’accounts, individual CBCA criteria, as well as the development of criminal experienceand familiarity with the event and setting. Implications for triers of fact and suggestionsfor future research are considered.

Ninety-five dental care patients participated in a quasi-experiment in which they were interviewed twice about dental visits they had made during thepast ten years. Objective truth was established by analysing their dental records. The main purpose of the study was to investigate to what extent con-text-specific cues could facilitate particularization (i.e., recollection of events and details) of repeated and similar events. A mixed design was employedand the effects of three types of cues were explored: two types of context-specific cues vs. cues commonly used in police practise when interviewingplaintiffs. In line with our hypothesis, context-specific cues tended to be more effective for recollection of individual events than the comparison cues.In addition, context-specific cues generated more details than the comparison cues and the difference was marginally significant. Rehearsal of the memo-ries by telling them to others was associated with an increased number of recollected events and details. The results are discussed from a legal psychol-ogy perspective with focus on recollection of repeated abuse.

Memory for repeated events is relevant to legal investigations about repeated occurrences. We investigated how two measures of specificity (number of events referred to and amount of detail reported about the events) were influenced by interviewees' age, number of experienced events, interviewer, perceived unpleasantness, and memory rehearsal. Transcribed narratives consisting of over 40.000 utterances from 95 dental patients, and the corresponding dental records, were studied. Amount of detail was measured by categorizing the utterances as generic, specific, or specific-extended. We found that the two measures were affected differently by all five factors. For instance, number of experienced events positively influenced number of referred events but had no effect on amount of detail provided about the events. We make suggestions for future research and encourage reanalysis of the present data set and reuse of the material.

In 2012, Swedish dental care patients (n = 95) participated in a quasi-experiment in which they were interviewed twice about dental visits they had made between 2002 and 2012. For verification purposes, the participants' narratives were compared to the dental records. The qualitative data was quantified, stored as a .csv file, and supplemented with a codebook in plain text. All study materials are freely available online. The data can be reused to further analyse memory for repeated events. The data can be used both as data from an experiment (including both interviews) and as single interview data (including data only from the first interview, i.e., before the respondents were provided with memory cues).
