ABSTRACT

No-body homicide cases are typically difficult to investigate, owing to the lack of forensics and leads. Researchers in the fields of forensics, criminology, and psychology have attempted to provide assistance to these investigations through their respective disciplines. The focus of the current case study review is on a combined approach to assisting in no-body homicides and cold cases. The proposed approach will outline a geographical profiling technique that has previously been used in no-body homicide investigations, Winthropping. Alongside this, forensic linguistic analyses will be outlined to show how a combination may provide fresh leads and investigative avenues for further exploration. A series of 4 real-world cases in which bodies were moved, dumped, and hidden by a suspect, who subsequently revealed knowledge of the clandestine grave are given. The aim is that readers from related fields and disciplines might synergistically collaborate to develop the area and further help in these cases.

ABSTRACT

The aim of the current study was to compare and contrast non-cannibalistic and cannibalistic serial killers. Using case study data, the present study assessed common patterns among the life histories of cannibalistic serial killers compared to those of a control sample of serial killers that did not commit cannibalism. These include but are not limited to childhood experiences, socio-economic status, biological abnormalities and life events. Results indicated that factors that may differentiate cannibals from non-cannibals likely result from childhood influences, rather than influences at the time of the kill. Findings may be used to identify potential warning signs or triggers for cannibalistic behaviour.

ABSTRACT

Every year, more children and youths are sent to Secure Children's Homes while moving through the criminal justice system. Aggressive and violent incidents in these settings are common, and staff are often required to intervene and restrain violent individuals. The research literature has many examples of aggression and violence questionnaires and measures; however, for staff in communal areas it is the observable behaviors that they react to most. The current research, therefore, analyzed observable behaviors leading-up to violent episodes, and used Behavior Sequence Analysis to highlight the typical chains of behaviors that tend toward violence. The outcomes of this research show pathways to violence that staff can use to highlight potential spirals of aggression and violence. The current results show the links between non-confrontational behaviors (e.g., talking) through to more confrontational (staring, approaching, and pushing others). Overall, the research forms the foundation for future investigation into these and similar settings and outlines a novel approach to understanding violence escalation in a way that can be interpreted and used by service staff.

ABSTRACT

The aim of the current research was to provide a novel method for mapping the developmental sequences of serial killers' life histories. An in-depth biographical account of serial killers' lives, from birth through to conviction, was gained and analyzed using Behavior Sequence Analysis. The analyses highlight similarities in behavioral events across the serial killers' lives, indicating not only which risk factors occur, but the temporal order of these factors. Results focused on early childhood environment, indicating the role of parental abuse; behaviors and events surrounding criminal histories of serial killers, showing that many had previous convictions and were known to police for other crimes; behaviors surrounding their murders, highlighting differences in victim choice and modus operandi; and, finally, trial pleas and convictions. The present research, therefore, provides a novel approach to synthesizing large volumes of data on criminals and presenting results in accessible, understandable outcomes.

ABSTRACT

Stalking is a complex issue involving multiple behaviors and interactions between the stalker and their target. Research has typically involved grouping risk behaviors related to stalking; however, the research question in the current research was to what extent a temporal method would allow investigators to map the dynamics of stalking. Behavior Sequence Analysis is a form of systems analysis that examines sequences of events over time, providing statistically significant results from complex real-world data. The Behavior Sequence Analysis method was applied to 39 participants' detailed accounts of stalking written in online forums. The study provides illustration of the antecedents of stalking and how it may initiate and develop through to end of contact. Both stalker behavior and decisions made by victim were included in the models. The results show multiple patterns of stalkers' behaviors; however, the results also clearly show that victims need not perform many behaviors for stalkers to continue with their actions. A main finding was how many behavior transitions occurred before victims felt a significant problem. A large number of participants indicated that they (repeatedly) reported their case of stalking to police and authorities; however, they were mostly dismissed or felt that police did not stop the stalker's actions. A major implication of the current research is providing a novel method to produce a framework that may be used to operationalize definitions of stalking based on coherent frameworks of stalkers' behaviors over time.

ABSTRACT

ISSUES ADDRESSED: Although cannabis use is still illegal in most places around the world, it remains a widely used drug. The recreational use of cannabis has been linked to multiple mental wellbeing issues, including psychosis, depression and anxiety. The objective of this study was to investigate the temporal dynamics of cannabis use in relation to mental health issues. METHODS: The current research uses a novel methodological approach, behaviour sequence analysis, to understand the temporal relationship between recreational cannabis use and surrounding issues related to mental wellbeing, in a sample of 61 participants who had written autobiographical accounts online. RESULTS: The results indicated a bi-directional temporal ordering between cannabis use and mood disorders. Cannabis use preceded psychosis and can also exacerbate symptoms of psychosis, depression and anxiety. Findings also suggested that low self-esteem may be a predictor of future cannabis use. CONCLUSIONS: Research shows a link between mood disorders and recreational cannabis use. The BSA method can be used in applied settings to map pathways in individuals' life histories. SO WHAT?: The current study shows the sequential links between cannabis use and psychosis, depression and anxiety. Results show there is no single clear pathway and clinical practitioners should focus on a wider range of factors in individual's case histories.

ABSTRACT

The causes of false confessions are an important issue in legal studies and forensics. Recent advances in DNA testing have increased the number of proven false confessions; however, there are probably many cases without scientific evidence to refute the guilty verdict. The current research provides a novel approach to understand the structure and process of police interrogation techniques, in the United States behaviour sequence analysis. This method allows complex interactions in interrogations to be broken down and the progression of techniques analysed clearly. A case study is provided of an individual who confessed to a series of very serious crimes. The results show that several psychological techniques, such as leading statements, pressure, empathy, and inducements, are used, in increasing frequency, which resulted in the suspect's confession. This research provides support for behaviour sequence analysis as a new method to understand the structure of police interrogations and how psychological techniques may be used to gain false confessions.

ABSTRACT

OBJECTIVES: This preliminary study examined whether implicit doping attitude, explicit doping attitude, or both, predicted athletes' vigilance towards unintentional doping. DESIGN: A cross-sectional correlational design. METHODS: Australian athletes (N=143;Mage=18.13, SD=4.63) completed measures of implicit doping attitude (brief single-category implicit association test), explicit doping attitude (Performance Enhancement Attitude Scale), avoidance of unintentional doping (Self-Reported Treatment Adherence Scale), and behavioural vigilance task of unintentional doping (reading the ingredients of an unfamiliar food product). RESULTS: Positive implicit doping attitude and explicit doping attitude were negatively related to athletes' likelihood of reading the ingredients table of an unfamiliar food product, and positively related to athletes' vigilance towards unintentional doping. Neither attitude measures predicted avoidance of unintentional doping. Overall, the magnitude of associations by implicit doping attitude appeared to be stronger than that of explicit doping attitude. CONCLUSIONS: Athletes with positive implicit and explicit doping attitudes were less likely to read the ingredients table of an unknown food product, but were more likely to be aware of the possible presence of banned substances in a certain food product. Implicit doping attitude appeared to explain athletes' behavioural response to the avoidance of unintentional doping beyond variance explained by explicit doping attitude.

ABSTRACT

Modelling data have provided good evidence to support the efficacy of a minimum pricing policy for alcoholic beverages as a means to reduce alcohol consumption and risky and harmful drinking. The aim of the present study was to investigate attitudes and beliefs towards a minimum price policy for alcohol among members of the general public in Western Australia (WA). The study also explored what factors might promote acceptance of the policy. Eleven focus groups, comprising participants from a broad range of backgrounds in WA, were conducted. Using a facilitator-administered semi-structured interview schedule participants discussed their beliefs about the policy and how its acceptability might be promoted. Transcriptions of discussions were analysed using qualitative inductive content analysis for emergent themes. Three major themes emerged: attitudes towards the policy, beliefs about effectiveness and strategies to increase acceptability. Participants expressed negative attitudes towards the policy and thought that it would lead to increased crime, drug use and financial strain. Participants identified the policy as unfair on disadvantaged groups, and suggested that individuals would find a way to procure alcohol regardless of minimum pricing policies. Suggestions to make the policy more acceptable included increasing alcohol education and directing the revenue towards alcohol reduction initiatives. Participants' negative views and perceived lack of effectiveness corroborate research conducted in the UK. Information and education campaigns aimed at reducing misunderstanding of the policy and highlighting its effectiveness may help to promote greater acceptability.

ABSTRACT

Binge drinking is associated with deleterious health, social and economic outcomes. This study explored the lay understanding of the causes of binge drinking in members of the general public in the United Kingdom and Australia. Participants in the United Kingdom (N = 133) and Australia (N = 102) completed a network diagram exercise requiring them to draw causal paths and provide path strength ratings between 12 candidate factors (24-h opening, age, alcohol advertizing, alcohol availability, boredom, drinking culture, income, low cost, parental influence, peer pressure, stress and supermarket discounts) and binge drinking. Results indicated good consistency in paths across samples, although differences in frequency and strength ratings for some paths were found. Drinking culture, peer pressure and low alcohol cost were perceived as direct causes of binge drinking in both samples. Low alcohol cost and drinking culture were most frequently viewed as direct causes of binge drinking in UK and Australian participants, respectively. Supermarket discounts and low cost of alcohol were most frequently viewed as indirect causes of binge drinking by UK and Australian samples. Findings reflect general awareness and prominence of factors affecting binge drinking in both national groups. Findings may inform the development of campaigns to promote public support policies to curb binge drinking.

ABSTRACT

Despite difficulties in interpretation, nonverbal communication is especially important in forensic settings, such as police investigations. Three distinct clusters of personality disorders have been outlined as being associated with criminal behaviour. Understanding the similarities and differences between these personality clusters and nonverbal communication could help investigators look for key signs of psychological distress or deception. The current research proposes a novel approach to nonverbal communication: behaviour sequence analysis (BSA). An application of this approach is outlined to investigate whether criminals with different personality types are better at concealing emotions and nonverbal communication when being interrogated. The results indicate that while sequences are generally similar across clusters, individuals from different personality clusters exhibit unique patterns. This research provides an initial step towards a new area of nonverbal communication research and application, which could be used in future research to highlight increased possibility of deception or concealment of emotion.

ABSTRACT

Caudwell, KM and Keatley, DA. The effect of men's body attitudes and motivation for gym attendance. J Strength Cond Res 30(9): 2550-2556, 2016-The current study integrates men's body attitudes with implicitly and explicitly measured motivation to investigate the role of these factors in predicting gym attendance. Male participants (N = 99) who regularly attended a gym were recruited to participate in an online questionnaire. Participants completed implicit and explicit measures of motivation, explicitly measured men's body attitudes, and reported the average number of gym visits per week. Attitudes related to body fat and explicitly measured autonomous motivation significantly predicted typical gym attendance. Implicitly measured motivation significantly and negatively predicted gym attendance. Results indicate some support for a dual-systems account of gym attendance. Men's body attitudes and autonomous motivation influences gym attendance; however, implicitly measured motivation showed antagonistic effects. Although individuals may explicitly state their autonomous motivation for gym attendance, attendance may also be influenced at the explicit level. Health and fitness professionals may improve gym attendance by focusing on people's reasons for attending a gym, facilitating autonomous motivation in clients, and minimizing the influence of controlled reasons for exercise.

ABSTRACT

BACKGROUND: Excessive alcohol consumption has significant adverse economic, social, and health outcomes. Recent estimates suggest that the annual economic costs of alcohol in Australia are up to AUD $36 billion. Policies influencing price have been demonstrated to be very effective in reducing alcohol consumption and alcohol-related harms. Interest in minimum pricing has gained traction in recent years. However, there has been little research investigating the level of support for the public interest case of minimum pricing in Australia. OBJECTIVE: This article describes protocol for a study exploring Western Australian (WA) public knowledge, understanding, and reaction to a proposed minimum price policy per standard drink. METHODS: The study will employ a qualitative methodological design. Participants will be recruited from a wide variety of backgrounds, including ethnic minorities, blue and white collar workers, unemployed, students, and elderly/retired populations to participate in focus groups. Focus group participants will be asked about their knowledge of, and initial reactions to, the proposed policy and encouraged to discuss how such a proposal may affect their own alcohol use and alcohol consumption at the population level. Participants will also be asked to discuss potential avenues for increasing acceptability of the policy. The focus groups will adopt a semi-structured, open-ended approach guided by a question schedule. The schedule will be based on feedback from pilot samples, previous research, and a steering group comprising experts in alcohol policy and pricing. RESULTS: The study is expected to take approximately 14 months to complete. CONCLUSIONS: The findings will be of considerable interest and relevance to government officials, policy makers, researchers, advocacy groups, alcohol retail and licensed establishments and organizations, city and town planners, police, and other stakeholder organizations.

ABSTRACT

We applied the strength-energy model of self-control to understand the relationship between self-control and young athletes' behavioral responses to taking illegal performance-enhancing substances, or "doping." Measures of trait self-control, attitude and intention toward doping, intention toward, and adherence to, doping-avoidant behaviors, and the prevention of unintended doping behaviors were administered to 410 young Australian athletes. Participants also completed a "lollipop" decision-making protocol that simulated avoidance of unintended doping. Hierarchical linear multiple regression analyses revealed that self-control was negatively associated with doping attitude and intention, and positively associated with the intention and adherence to doping-avoidant behaviors, and refusal to take or eat the unfamiliar candy offered in the "lollipop" protocol. Consistent with the strength-energy model, athletes with low self-control were more likely to have heightened attitude and intention toward doping, and reduced intention, behavioral adherence, and awareness of doping avoidance.

ABSTRACT

Research into individuals' intended behavior and performance has traditionally adopted explicitly measured, self-report constructs, and outcomes. More recently, research has shown that completing explicit self-report measures of constructs may effect subsequent behavior, termed the "mere measurement" effect. The aim of the present experiment was to investigate whether implicit measures of motivation showed a similar mere measurement effect on subsequent behavior. It may be the case that measuring the implicit systems affects subsequent implicit interventions (e.g., priming), observable on subsequent behavior. Priming manipulations were also given to participants in order to investigate the interaction between measurement and priming of motivation. Initially, a 2 [implicit association test (IAT: present vs. absent) ×2 (Prime: autonomous vs. absent) and a 2 (IAT: present vs. absent) × 2 (Prime: controlled vs. absent)] between participants designs were conducted, these were them combined into a 2 (IAT: present vs. absent) ×3 (Prime: autonomous vs. controlled vs. absent) between participants design, with attempts at a novel task taken as the outcome measure. Implicit measure completion significantly decreased behavioral engagement. Priming autonomous motivation significantly facilitated, and controlled motivation significantly inhibited performance. Finally, there was a significant implicit measurement × priming interaction, such that priming autonomous motivation only improved performance in the absence of the implicit measure. Overall, this research provides an insight into the effects of implicit measurement and priming of motivation and the combined effect of completing both tasks on behavior.

ABSTRACT

While we agree that personal financial incentives (PFIs) may have some utility in public health interventions to motivate people in the uptake and persistence of health behaviour, we disagree with some of the sentiments outlined by Lynagh et al. (Int J Behav Med 20:114-120, 2012). Specifically, we feel that the article gives a much stronger impression that PFIs will likely lead to long-term behaviour change once the incentive has been removed than is warranted by current research. This claim has not received strong empirical support nor is it grounded in psychological theory on the role of incentives and motivation. We also feel that the presentation of some of the tenets of self-determination theory by the authors is misleading. Based on self-determination theory, we propose that PFIs, without sufficient consideration of the mechanisms by which external incentives affect motivation and the interpersonal context in which they are presented, are unlikely to lead to persistence in health behaviour once the incentive is removed. We argue that interventions that adopt PFIs as a strategy to promote health-behaviour change should incorporate strategies in the interpersonal context to minimise the undermining effect of the incentives on intrinsic motivation. Interventions should present incentives as informational regarding individuals' competence rather than as purely contingent on behavioural engagement and emphasise self-determined reasons for pursuing the behaviour.

ABSTRACT

The current research tested the hypothesis that individuals engaged in long-term efforts to limit food intake (e.g., individuals with high eating restraint) would have reduced capacity to regulate eating when self-control resources are limited. In the current research, body mass index (BMI) was used as a proxy for eating restraint based on the assumption that individuals with high BMI would have elevated levels of chronic eating restraint. A preliminary study (Study 1) aimed to provide evidence for the assumed relationship between eating restraint and BMI. Participants (N = 72) categorized into high or normal-range BMI groups completed the eating restraint scale. Consistent with the hypothesis, results revealed significantly higher scores on the weight fluctuation and concern for dieting subscales of the restraint scale among participants in the high BMI group compared to the normal-range BMI group. The main study (Study 2) aimed to test the hypothesized interactive effect of BMI and diminished self-control resources on eating behavior. Participants (N = 83) classified as having high or normal-range BMI were randomly allocated to receive a challenging counting task that depleted self-control resources (ego-depletion condition) or a non-depleting control task (no depletion condition). Participants then engaged in a second task in which required tasting and rating tempting cookies and candies. Amount of food consumed during the taste-and-rate task constituted the behavioral dependent measure. Regression analyses revealed a significant interaction effect of these variables on amount of food eaten in the taste-and-rate task. Individuals with high BMI had reduced capacity to regulate eating under conditions of self-control resource depletion as predicted. The interactive effects of BMI and self-control resource depletion on eating behavior were independent of trait self-control. Results extend knowledge of the role of self-control in regulating eating behavior and provide support for a limited-resource model of self-control.

ABSTRACT

BACKGROUND: Exposure to smoking-related cues leads to increased urge to smoke in regular cigarette smokers and resisting these urges requires considerable self-control. PURPOSE: Adopting a resource depletion model, two studies tested the hypothesis that resisting smoking urges depletes self-control resources. METHODS: Adopting a within-participants randomized cross-over design, participants (study 1, N = 19; study 2, N = 32) were exposed to smoking-related (study 1: smoking images; study 2: cigarette cue-exposure task) and neutral (study 1: neutral images; study 2: drinking-straw task) cues with presentation order randomized. After each cue set, participants completed self-control tasks (study 1: handgrip task; study 2: handgrip and Stroop tasks), performance on which constituted dependent measures of self-control. RESULTS: Self-control task performance was significantly impaired when exposed to smoking-related cues compared to neutral cues. No significant presentation-order effects, or interaction effects between stimulus and presentation order, were found. CONCLUSIONS: Findings corroborate our hypothesis that resisting smoking urges depletes cigarette smokers' self-control resources and suggests that self-control capacity is governed by a limited resource.
