Deception Traits in Psychological Interviewing

Deception researchers have attempted to improve people’s ability to detect deceit by teaching them which cues to pay attention to. Such training only yields limited success because, we argue, the nonverbal and verbal cues that liars spontaneously display are faint and unreliable. In recent years, the emphasis has radically changed and the current focus is on developing interview techniques that elicit and enhance cues to deception. We give an overview of this innovative research. We also consider to what extent current deception research can be used to fight terrorism. We argue that researchers should pay particular attention to settings that are neglected so far but relevant for terrorism, such as (i) lying about intentions, (ii) examining people when they are secretly observed and (iii) interviewing suspects together. We will commence this paper with general information that puts our reasoning into context. That is, we turn briefly to physiological and neurological lie detection methods that are often discussed in the media, then to the theoretical underpinnings of nonverbal and verbal cues to deceit, and the research methods typically used in nonverbal and verbal lie detection research.     

Gender,Indigeneity, and the Criminal Courts: A Narrative Exploration of Women's Sentencing in Western Australia

Ethel Rosenberg's prison letters illustrate women's prison writing at a transitional point. Preceding her work are prison writings that focus on self-justification and autobiography; afterward come texts that assert the writer's pride and challenge the penal system and society. Rosenberg's correspondence includes elements of both traditional and contemporary women's prison literature. Along traditional lines, her letters focus on family matters and her own mental state as she attempts to adapt to imprisonment. In their outright assertions of pride in self and anger at perceived injustice, Rosenberg's letters point ahead to the writing of women inmates today.     

Cues to Deception and Ability to Detect Lies as a Function of Police Interview Styles

In Experiment 1, we examined whether three interview styles used by the police, accusatory, information-gathering and behaviour analysis, reveal verbal cues to deceit, measured with the Criteria-Based Content Analysis (CBCA) and Reality Monitoring (RM) methods. A total of 120 mock suspects told the truth or lied about a staged event and were interviewed by a police officer employing one of these three interview styles. The results showed that accusatory interviews, which typically result in suspects making short denials, contained the fewest verbal cues to deceit. Moreover, RM distinguished between truth tellers and liars better than CBCA. Finally, manual RM coding resulted in more verbal cues to deception than automatic coding of the RM criteria utilising the Linguistic Inquiry and Word Count (LIWC) software programme.In Experiment 2, we examined the effects of the three police interview styles on the ability to detect deception. Sixty-eight police officers watched some of the videotaped interviews of Experiment 1 and made veracity and confidence judgements. Accuracy scores did not differ between the three interview styles; however, watching accusatory interviews resulted in more false accusations (accusing truth tellers of lying) than watching information-gathering interviews. Furthermore, only in accusatory interviews, judgements of mendacity were associated with higher confidence. We discuss the possible danger of conducting accusatory interviews.     

Discrimination between sediment and soil samples for forensic purposes using elemental data: an investigation of particle size effects

This paper reports the results of an investigation to quantify variations in elemental concentrations amongst different particle size fractions obtained from a suite of sediment samples collected from the River Avon, UK. Concentrations of 49 elements determined by inductively coupled plasma spectrometry (ICP-AES and ICP-MS) were compared using conventional and multivariate statistical methods in order to assess compositional differences between different size fractions and between different samples. The results showed significant differences between different size fractions and the bulk sediments, but indicated that all of the size fractions considered (<150, 63-150, 20-63 and <20microm) provided an adequate basis on which to identify associations and differences between samples. It was concluded that, while in certain specific circumstances it may be most appropriate to make forensic comparisons based on a very narrowly defined particle size range, for the majority of purposes the <150microm fraction provides the best compromise between sample size requirements and data resolution.     

“Undoing” (or Symbolic Reversal) at Homicide Crime Scenes

A closed case file review of a nonrandom national sample of 975 homicides disclosed 11 cases (1.13%) of undoing, wherein offenders engaged in crime scene behavior that has been considered an attempt to symbolically reverse the murder. The frequency of the various methods of undoing involved the use of blankets to cover the victim's body (55%), positioning the body (55%), use of a bed or couch (42%), washing the body (36%), using pillows (36%), as well as removing clothing and adding other types of adornments (27%). Ten of the 11 offenders were male, and one was female; all 12 victims were female. Ten of the 12 victims were family members or relationship intimates. These findings are consistent with prior reports which concluded that the motivation for undoing behavior is an attempt to compensate for guilt or remorse for having committed the homicide.     

Fragmentation and cooperation: the evolution of organized crime in Mexico

Some researchers suggest that the observed boom in the levels of violence in Mexico since 2008 are a consequence of placing federal military forces in states with a significant organized crime presence. However, little has been said about the role of the changeable, competitive, and violent nature of criminal organizations on this increasing violence. Using the literature on inter- and intra-state conflicts as matter of analogy to explain organized crime developments in Mexico, fragmentation and cooperation seem to be determinant forces that alter the equilibrium within Mexican criminal groups, affecting their territorial control. By using a private dataset gathered by the Drug Policy Program at the Center for Economic Research and Teaching (CIDE), we examine the evolution of criminal organizations in Mexico by focusing on their different alliances and fragmentations from December 2006 to December 2011. Our analysis suggests that violence is a consequence not only of the law enforcement actions, but also of the fragmentation and cooperation within and between private groups.     

Students’ Feelings of Safety,Exposure to Violence and Victimization,and Authoritative School Climate

Although many students feel unsafe at school, few malleable factors have been identified to increase students’ feelings of safety. Drawing on criminological behavior control theories, this study posits authoritative school climate as one such factor. With data from two nationally representative datasets, this study uses path analysis to examine the relationship between authoritative school climate and feelings of safety, as well as the extent to which this relation is explained by exposure to violence and victimization. Across both datasets, a more authoritative school climate was associated with increased feelings of safety at school. Both models also indicated that this relationship was explained in part by reduced exposure to violence and victimization, although the strength of this indirect effect varied across models. These findings suggest that strengthening students’ relationships with adults and increasing the fairness and consistency of rules in the school may both reduce exposure to violence and victimization and help students feel safer at school.     

Skeletal Trauma Resulting From Fatal Low (≤3 m) Free Falls: An Analysis of Fracture Patterns and Morphologies

The skeletal trauma resulting from fatal low (≤3 m) free falls is poorly researched and understood by forensic practitioners. The aim of this study was to identify the types of skeletal trauma resulting from low falls through investigating fracture patterns and morphologies. Skeletal trauma was analyzed using full‐body postmortem computed tomography scans of 145 individuals who died from a low free fall. Trauma was then contextualized to the variables that influence how a person falls using multiple logistic regression. Results showed fracture patterning primarily involved the axial skeleton and that there were a number of patterns significantly associated with the height fallen, pre‐existing health conditions, and age. Analysis of fracture morphologies showed 108 possible fracture types, six of which were significantly associated with the height fallen. Understanding the skeletal trauma characteristic of low free falls will further inform anthropological interpretations of trauma in cases where a fall may be considered the possible mechanism.     

Quality of low secure services in the UK: development and use of the Quality of Environment In Low Secure Services (QELS) checklist

Low secure services provide care for psychiatric patients whose risk cannot be safely managed in other settings. The physical environment in these units plays an important role in supporting recovery and risk management. We developed the Quality of Environment in Low secure Services (QELS) checklist to assess the quality of the physical environment of these services. Using recommendations from previously published standards we piloted a draft checklist with a weighted scoring system reflecting the views of patients and providers. The checklist showed good criterion validity and inter-rater reliability. Data collected from 33 low secure services showed considerable variation in the quality of the physical environment. The QELS checklist provides an accessible and reliable means for managers and clinicians to assess whether the quality of the physical environment of low secure units meets recommended standards and can be used to support efforts to improve the quality of care delivered by these services.     

Interpersonal Relationships and the Development of Behavior Problems in Adolescents in Urban Schools: A Longitudinal Study

The purpose of this study was to investigate the trajectories of behavioral problems for a sample of predominately minority adolescents (n = 212, 91% African-American and/or Hispanic, 45% boys, 55% girls) in a large, urban school district and to determine the impact of parental and peer relationships, gender, and risk status on their development during middle and high school. Multi-level growth modeling was the primary statistical procedure used to track internalizing and externalizing behavioral problems across time. Results indicated that behavioral problems as rated by students’ teachers declined significantly for both boys and girls, a finding that is in direct contrast to previous studies of adolescent behavior. The quality of parental relationships was a strong predictor of both types of behavior whereas the quality of peer relationships predicted only internalizing behavioral symptoms. These findings suggest that behavioral trajectories may be somewhat unique for this population underscoring the need for additional research in this area. The findings also have implications for intervening with children and youth who display behavioral problems during critical developmental periods.
