- Background/Rational Every day people decide how to travel to their out-of-home activities. What is important for them when choosing the mode of transportation? Are those things predictors of attitudes towards modes of transportation along with driving habits and satisfaction with daily travel? Does being more or less satisfied affect people’s attitudes? Method A survey was mailed to a sample of 3,000 Swedish residents in rural, semi-rural and urban areas. The questionnaire consisted of four sections: driving habits, satisfaction, important aspects when choosing mode of daily commuting and socio-demographics measurements. Results Factor analysis was conducted regarding “satisfaction with daily commuting”, “important aspects for mode choice of commuting” and “driving habits” (KMO = .74; .76; 79, respectively). The retained factors were used in multiple regressions analyses as predictors of attitudes towards car, public transport and bike (R2 = .32; .11; .16, respectively). Conclusions “Driving habits” was the main predictor for attitudes towards car while “socially desirable aspects” was the most important factor to predict attitudes towards public transport and bike. Living in big cities negatively affected attitudes toward car and satisfaction with daily commuting was a minor predictor for all modes of transportation. Action/Impact Attitudes towards modes of commuting are predicted by people’s habits and what they value as important when commuting. Knowing what they value when choosing modes of transportation gives support to implement accurate and effective interventions, policies and new services that promote sustainability in transportation.

The effects of approach and avoidance states on lie-detection accuracy
- 2017

- Three experiments examined perceivers’ lie-detection performance under different self-regulatory states. Overall, participants in approach and avoidance states did not differ in their ability to discriminate between truthful and deceptive messages, but approach participants displayed impaired performance relative to controls.

Alcohol, crime and memory. Intoxicated eyewitnesses delayed recall of a kidnapping.
- 2012

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- 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.

- 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.

Effect of the degree of alcohol intoxication on eyewitness memory for a violent crime: Identification accuracy in lineup
- 2011

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

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.
