  • Alcohol, crime and memory. Intoxicated eyewitnesses delayed recall of a kidnapping.
  • 2012
  • Ingår i: Svenska föreningen för Alkohol- och Drogforskning, konferens 8-9 November, Norrköping.

    • Alcohol is involved in 50-70% of violent crimes in Sweden. Eyewitness memory is a valuable source in investigations and it is common that the police interview alcohol intoxicated eyewitnesses. There are few studies on how alcohol affects witness memory. This study investigated how different doses of alcohol affected eyewitness recall one week after witnessing a crime and potential sex differences. The participants (N = 126) were healthy adults and were randomly assigned to either a control group, 0.0 g/kg ethanol (N = 42), a lower alcohol dose group, 0.4 g/kg ethanol (N = 40), or a higher alcohol dose group, 0.7 g/kg ethanol (N = 44). After 15 minutes consumption in a laboratory, participants witnessed a film showing a kidnapping of a woman by two men. The witnesses were interviewed about the crime one week later in a sober state. Witnesses in the higher alcohol dose group recalled fewer details compared to witnesses in the lower alcohol dose group. The amount of alcohol consumed did not have an impact on accuracy. Women and men reached the same blood alcohol concentration and no sex differences were found in recall. Interestingly, although the witnesses in the high alcohol dose group reported less information, their testimony was as correct as the testimony given by witnesses in the control group and the lower alcohol dose group. Despite the interesting results, more studies are needed before recommendations to the legal system can be made.

  • Alcohol intoxicated eyewitnesses´ delayed recall of a kidnapping.

    • This study investigated how different doses of alcohol affected eyewitness recall. Participants (N = 126) were randomly assigned to three groups with different blood alcohol concentration (BAC), either a control group (mean BAC 0.00%, N = 42), a lower alcohol dose group (mean BAC 0.04%, N = 40), or a higher alcohol dose group (mean BAC 0.06%, N = 44). After consumption in a laboratory, participants witnessed a film of a mock crime where a woman was kidnapped by two men. One week after, the witnesses were interviewed in a sober state, by interviewers who were blind to which beverage the witnesses had consumed the week before. The main results showed that witnesses with the higher intoxication level recalled fewer details compared to witnesses with the lower intoxication level. The amount of alcohol consumed did not have an impact on the accuracy rate. No sex differences were found. We conclude that more studies are needed before recommendations can be made to an applied setting, but this study showed that alcohol may have a negative impact on eyewitness recall.

  • Alcohol-intoxicated eyewitnesses’ memory: The effects of recall format, recall time, and repeated interviewing
  • 2015
  • Ingår i: Annual convention for Association for Psychological Science (APS), 2015-05-22, New York City, USA.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Intoxicated eyewitnesses are common, but are often discredited by investigators and in courts. The aim was to examine how intoxication (control vs. alcohol), recall format (free vs. cued), recall time (immediate vs. one week delayed), and repeated interviewing affects witnesses’ memory. The participants (N = 99) were randomly assigned to consume either juice or alcohol (0.7 g/kg), and they then witnessed a filmed staged crime. The participants were asked for a free recall followed by cued recall, either a) immediately and after a one week delay or b) only after a one week delay. Intoxicated witnesses recalled the same amount of information as sober ones in the cued recall phase, but significantly less details than sober ones in the free recall phase. However, all witnesses recalled more details and had a higher accuracy rate in free recall compared to cued recall. Overall, there was no difference between sober and intoxicated witnesses with respect to their accuracy rate. Also, all witnesses reported more details and were more accurate at the immediate compared to the delayed recall. However, conducting two recalls were more superior to one recall, since all witnesses recalled new details with relatively high accuracy at the second recall. Results are discussed in the light of their theoretical and applied relevance.

  • Alcohol-intoxicated witnesses: A review of the current literature and new steps forward.
  • 2014
  • Ingår i: Nordic Network for Psychology and Law (NNPL), 7-8 November 2014, Oslo, Norway.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Eyewitnesses often provide central investigative leads in many criminal cases, and are often the sole source of evidence. Many witnesses are under the influence of alcohol during the crime, and/or during the investigative interview and line-up. There is evidence that jurors and expert witnesses perceive intoxicated witnesses as more cognitively impaired and less credible than sober ones. The few studies that have examined the effects of alcohol on witness memory for events cast doubt on whether expert witnesses’ and jurors’ inferences are warranted. That is, in experimental studies, intoxicated witnesses rarely differ from sober or placebo witnesses in terms of accuracy and quantity of information recalled or in their ability to recognize a perpetrator in a lineup. At the few occasions when a detrimental effect of alcohol on witness memory has been found it resulted in small differences between alcohol and sober or placebo participants, barely of any practical significance for law enforcement personnel. The present literature review indicates that intoxicated witnesses might be better than their reputation, and that witnesses who have a low to moderate intoxication level (BAC <0.10%) can be rather reliable sources of information in criminal investigations. However, limitations in the previous studies are highlighted and new steps of further research is discussed.

  • Bottled memories: On how alcohol affects eyewitness recall
  • 2013
  • Ingår i: Scandinavian Journal of Psychology. - : Wiley. - 0036-5564 .- 1467-9450. ; 54:3
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigated how different doses of alcohol affected eyewitness recall. Participants (N = 126) were randomly assigned to three groups with different blood alcohol concentration (BAC), either a control group (mean BAC 0.00%, N = 42), a lower alcohol dose group (mean BAC 0.04%, N = 40), or a higher alcohol dose group (mean BAC 0.06%, N = 44). After consumption, participants witnessed a movie of a mock crime and were interviewed one week later. The main results showed that witnesses with the higher intoxication level recalled fewer details compared to witnesses with the lower intoxication level. The amount of alcohol consumed did not have an impact on the accuracy rate. No sex differences were found. The results are discussed in the light of past research. We conclude that more studies are needed before recommendations can be made to an applied setting. Key words: Alcohol, eyewitness memory, recall, delayed interview, intoxicated witnesses.

  • Do Sober Eyewitnesses Outperform Alcohol Intoxicated Eyewitnesses in a Lineup?
  • 2013
  • Ingår i: European Journal of Psychology Applied to Legal Context. - 1889-1861. ; 5:1, s. 23-47
  • Tidskriftsartikel (refereegranskat)abstract
    • Although alcohol intoxicated eyewitnesses are common, there are only a few studies in the area. The aim of the current study is to investigate how different doses of alcohol affect eyewitness lineup identification performance. The participants (N = 123) were randomly assigned to a 3 [Beverage: control (0.0 g/kg ethanol) vs. lower (0.4 g/kg ethanol) vs. higher alcohol dose (0.7 g(kg ethanol)] X 2 (Lineup: target-present vs. target-absent) between-subject design. Participants consumed two glasses of beverage at an even pace for 15 minutes. Five minutes after consumption the participants witnessed a film depicting a staged kidnapping. Seven days later, the participants returned to the laboratory and were asked to identify the culprit in a simultaneous lineup. The result showed that overall, the participants performed better than chance; however, their lineup performance was poor. There were no significant effects of alcohol intoxication with respect to performance, neither in target-present nor target-absent lineups. The study's results suggest that eyewitnesses who have consumed a lower (0.4 g/kg ethanol) or a higher (0.7 g/kg ethanol) dose of alcohol perform at the same level as sober eyewitnesses in a lineup. The results are discussed in relation to the alcohol myopia theory and suggestions for future research are made.

  • Effect of the degree of alcohol intoxication on eyewitness memory for a violent crime: Identification accuracy in lineup
  • 2011
  • Ingår i: Oral presentation at The Nordic Network for Psychology and Law (NNPL), September 16-17 2011, Oslo, Norway.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction and Aim. In Sweden, 50-70% of all violent crimes are alcohol related (BRÅ, 2007, 2009). Eyewitnesses are valuable to the Police since they have seen the event and many crimes lack technical evidence like DNA. Due to the limited studies in the area, this ongoing experimental study might give valuable knowledge to the legal system concerning the assessment of alcohol intoxicated eyewitnesses and the credibility of their testimonies. Methods. The participants (N = 120 when finished) consists of healthy adult students. The study uses a 3 x 2 between- participants design with random assignment to alcohol beverage (none vs. moderate vs. high dose,) and lineup presentation (target present vs. target absent). Consumption time is 15 minutes in a laboratory with living room design. A movie depicting a staged kidnapping is shown to the participants and after 30 minutes of distracting filler tasks the participants are interviewed. One week later, the participants are presented the simultaneous lineup in order to identify the culprit from the movie and are also interviewed in more detail about the crime scene. Results and Conclusions. The data collection is ongoing during the spring of 2011. To this date, data from half of the participants has been collected. Results concerning identification accuracy will be presented and discussed at the NNPL conference in Oslo in September 2011.

  • Immediate or delayed recall: When is the best time to interview alcohol intoxicated eyewitnesses?
  • 2013
  • Ingår i: Oral presentation at The Nordic Network for Psychology and Law (NNPL), October 25-26 2013, Aarhus, Denmark.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction. Many violent crimes involve alcohol intoxicated eyewitnesses, but there are only a few studies on how alcohol affects eyewitness memory. Aim. The overall aim was to examine whether eyewitnesses, intoxicated as well as sober, recall more (and more accurate) information when interviewed immediately after witnessing a crime, compared to a delayed interview. Methods. The participants (N = 99) were randomly assigned to a 2 (Beverage: control vs. alcohol) x 2 (Recall trial: immediate and delayed vs. delayed only) mixed design. After a 15 minutes consumption time, a staged kidnapping on film was shown. Half of the participants (N = 48) were interviewed immediately and all (N = 100) had a one week delayed recall. Results. There was no difference between sober and intoxicated eyewitnesses in terms of amount of details, but intoxicated witnesses were less accurate. Eyewitnesses who had an immediate recall remembered significantly more and were more accurate at the delayed recall, than eyewitnesses who did not have an immediate recall. This regardless whether the eyewitnesses had consumed alcohol or not the week before. Conclusions. This study shows the importance of conducting an immediate interview, even when the witnesses are intoxicated with a low to moderate blood alcohol concentration.

  • Stumbling down memory lane: When to interview alcohol-intoxicated eyewitnesses?
  • 2014
  • Ingår i: Conference of European Association of Psychology and Law (EAPL), 25th of June 2014, St. Petersburg, Russia.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction. Many violent crimes are observed by alcohol intoxicated eyewitnesses, but there are only a few studies on how alcohol affects witness memory. Aim. The aim was to examine to what extent alcohol, time of interview (immediate vs. delayed) and recall trial (single vs. repeated) affect the completeness and accuracy of testimonies. Methods. Participants (N = 99) were randomly assigned to a 2 (Beverage: control vs. alcohol) x 2 (Recall: immediate and delayed vs. delayed only) mixed design. After a 15 minutes consumption time, a staged kidnapping on film was shown. Half of the participants (N = 48) were interviewed immediately and all (N = 99) had a one week delayed recall. Results. Overall, alcohol reduced the accuracy of the reports, but had no effect on the completeness of the testimonies. Regardless of intoxication level, the best recall performances were found when witnesses were interviewed immediately. Conclusions. The findings from this study indicates that intoxicated witnesses might report the same amount of details to the police, but be slightly less accurate compared to sober witnesses. More studies are needed to be conducted before recommendation to the legal system can be made.
