Missing person alerts: does repeated exposure decrease their effectiveness?

Objectives

Prospective person memory refers to situations where one is asked to be on the lookout for a missing or wanted individual. Some researchers have hypothesized that because people see missing person alerts for multiple people over a period of time, that people habituate to missing persons alerts much like they do to car alarms. The purpose of this research was to test that hypothesis.

Methods

Some participants saw three different mock missing person videos, depicting three different target individuals, with one video being shown on each of 3 days (Monday, Wednesday, Friday). Other participants engaged in unrelated tasks on the first 2 days and saw a single mock missing person video on the third day. All participants were told that if they saw a person from a mock missing person video and contacted the experimenters they would win a cash prize. On the final day of the study, the target individual was located in the hallway a short distance from the experiment room in a location that participants had to pass on their way out of the building.

Results

Correct sightings of the target individual were significantly lower in the multiple video condition than in the single video condition.

Conclusions

The results suggest that overuse of missing person alert systems can decrease their effectiveness in a manner consistent with a “car alarm” effect.

     

A mixed methods study of the mental health and criminal justice histories of missing persons

Approximately 35,000 people are reported missing each year in Australia; rates elsewhere are even higher, with a recent UK study suggesting that a person goes missing every 2 min. Missing persons place a significant burden on police services; it is interesting, therefore, that very little research attention has been paid to this topic. This mixed methods study aimed to address this significant gap by analysing the mental health and criminal justice histories of a sample of missing persons and comparing them to rates in the general community. The study found that both mental health and criminal justice histories were significantly overrepresented among missing persons compared to those in the general community, and that young people reported missing commonly displayed suicidal behaviour. Results highlight at risk groups and suggest that criminality is much more commonly implicated in missing person incidents than previously thought.     

Public and family support and concerns for providing DNA to law enforcement in long-term missing person cases

The identification of long-term missing persons and unidentified human remains is a global challenge. Many people stay on missing persons registers, with unidentified human remains stored for extended periods in mortuaries around the world. Research exploring public and/or family support for providing DNA in long-term missing persons cases is scarce. The aims of this study were to examine whether trust in police predicted the level of support for providing DNA and explore public/family support and concerns for providing DNA in such cases. Trust in police was measured through two widely used empirical attitude scales; “The Measures of Police Legitimacy and Procedural Justice”. Support and concerns for giving DNA were measured through four hypothetical missing persons case scenarios. The results showed more positive attitudes towards police legitimacy and procedural justice significantly predicted support, with the percentage level of positive support across the four case types as follows: cases involving a long-term missing child (89%), elderly adult with dementia (83%), young adult with a history of runaway (76%), with the lowest level of support for an adult with an estranged family (73%). Participants also reported more concerns about providing DNA when the missing person circumstances involved family estrangement. Understanding levels of public/family support and concerns around providing DNA to police in missing persons cases is vital to ensure that DNA collection practices reflect what the public/family support and, wherever possible, alleviate public concerns.     

The Successful Onset of Sex Offending: Determining the Correlates of Actual and Official Onset of Sex Offending

PurposeThe current study investigates the covariates of age of onset (actual and official) and cost avoidance of sex offending in first-time convicted sex offenders.MethodsThe current study utilized a large sample (n = 332) of federally sentenced first-time convicted adult male sex offenders. Actual onset was measured using self-report, victim statements, and police investigation notes. Official onset was measured using age at first conviction. Cost avoidance was measured as the time gap between actual and official onset.ResultsFirst, while most offenders initiated their sexual criminal career in their early adult years (25–35 years) they were typically not arrested until middle adulthood. Second, the covariates for official onset are in line with cost avoidance, but not actual onset. Third, offenders best able to avoid costs were early starters with a conventional background (i.e., employed, absence of a conviction for a non-sex crime), targeting prepubescent children within the family context.ConclusionsWhile early actual onset offenders were more likely to target stranger victims, early official starters exhibited an unconventional background, prior criminal record, more extensive sexual criminal career, and targeted strangers. Thus, official, but not actual onset revealed a profile in line with prior research.     

Perceived criteria used by criminal justice and mental health professionals to predict dangerous behavior of mentally ill persons

A group of 163 Colorado mental health and criminal justice professionals were asked to rate the effectiveness of a set of predictors of violent behavior for mentally ill persons. Violent behavior and the characteristics of the offense were rated highest, followed by mental health and social factors respectively. Little variation existed between mental health and criminal justice groups with respect to which predictors were perceived as important. The rankings of the dangerous behavior predictors by criminal justice and mental health workers were highly correlated, suggesting agreement between the groups. A moderate correlation was found for the rankings of mental illness predictors. These factors were similar to those identified in previous research. Both groups perceived their predictors to be accurate.     

Fitting stories into professional legal education—the missing ingredient

Abstract

THIS ARTICLE considers the absence of story‐telling from legal education in England and Wales. This important aspect of persuasion is quite thoroughly considered in the academic and professional legal literature of the USA and Australia, for example, but has received very little attention in England, specifically when one looks at professional legal education and training. Currently, the training programme for law graduates (who will qualify as barristers1) devotes considerable time to training in advocacy skills and often in case preparation as well but typically little or no time to the concept of story‐telling or story‐framing. These training programmes do not seek to inform our lawyers‐in‐waiting about the ways in which fact‐finders make decisions.

If one actively seeks information and learned comment on the topic of story‐telling, the legal trainer in England is forced to turn elsewhere, usually to the USA. Undoubtedly, research is ongoing in England on the topic of juror decision‐making but at present this tends to be the exclusive province of psychologists. This article will suggest that this topic is a vital missing ingredient in professional legal training in England and that space must be made for its inclusion in such training programmes. Consideration will be given to the most appropriate ways to facilitate this inclusion.

Life is not what one lived, but what one remembers and how one remembers it in order to recount it.2     

Using the cognitive interview with adults with mild learning disabilities

Abstract

Forty-seven adults with mild learning disabilities (mild intellectual disabilities) attending day-centres and thirty-eight adults from the general population viewed a videorecording of an accident. A day later the participants were interviewed using either a cognitive interview (CI) or a structured interview (SI, a control interview). Compared with their counterparts with learning disabilities, adults from the general population recalled more correct information and made fewer confabulations about persons and objects. Nevertheless, the type of interview had an impact. For both groups, the CI was more effective than the SI in enhancing recall although, for the ‘learning disabilities’ group, the CI also produced a disproportionate increase in the reporting of person confabulations. All the same, the accuracy ratios were similar across interview types (80% for the CI and 82% for the SI). It is suggested that the CI could be helpful in assisting people with learning disabilities to provide information about events they have seen.     

The effect of perceived risk and victimization on plans to purchase a gun for self-protection

Purposes

To determine if perceived risk of criminal victimization, and past criminal victimization experiences, increases the likelihood of a person owning a gun for self-protection, and to determine if defects in past research concerning the way gun ownership was measured had obscured such effects.

Methods

We analyzed data on over 2,500 U.S. adults, using different ways of measuring gun ownership, and also analyzed future plans (among persons who did not own a gun at the time of the survey) to acquire a gun for self-protection. The latter procedure avoids the causal order problem attributable to the possibility that acquiring a gun might affect victimization risks and perceived risks, as well as the reverse.

Results

The estimated effect of perceived risk and prior victimization changed from being nonsignificant when household gun ownership was the dependent variable (as in most prior research) to being increasingly strong, and statistically significant, when gun ownership of the individual respondent for defensive reasons was measured. Further, once the causal order issue was side-stepped, risk and victimization showed even stronger, significant positive effects on planning to get a gun.

Conclusions

Crime affects gun ownership, in addition to any effects that gun ownership may have on crime.     

A social-cognitive model of animal cruelty

ABSTRACT

Recent decades have seen the emergence of social cognitive models of interpersonal aggression. These models, which have focused primarily on childhood aggression, have been the subject of extensive theoretical, methodological, and empirical attention. More recently, researchers have used social cognitive models to address adult interpersonal aggression as well as child abuse and neglect. This article will discuss the ways in which researchers can potentially extend this model to understand the abuse and neglect of animals. After a brief review of the literature on social-information processing, schemas, and normative beliefs about aggression, I will apply these mechanisms and findings to what we know about animal cruelty. I will also use current social cognitive models of aggression to describe potential directions for future research within the field of animal abuse and neglect scholarship.     

Associated Adults: Prospective Person Memory for Family Abducted Children

In family abductions, authorities sometimes release pictures of both missing children and associated adults. The effectiveness of this approach was tested in a prospective person memory experiment. Participants studied mock missing child posters including a picture of a child, a picture of a child alongside a picture of the correct adult, or a picture of a child alongside a picture of the incorrect adult. Participants then saw pictures of child/adult pairs with instructions to make a response to ‘alert authorities’ if the target individuals were seen. Including the picture of the correct adult on the poster, significantly improved recognition relative to the other two conditions. There was no significant effect of including the picture of the incorrect associated adult.     

Children's identification of unfamiliar voices on both target-present and target-absent lineups

ABSTRACT

A robust finding from the eyewitness literature is that children are as accurate as adults on target-present lineups from the age of five years, whereas they continue to make an erroneous false positive identification from a target-absent lineup up until around fourteen years of age (Pozzulo, J. D., & Lindsay, R. C. L. (1998). Identification accuracy of children versus adults: a meta-analysis. Law and Human Behavior, 22(5), 549–570). The current study explores whether the same pattern occurs when voices are used instead of faces. A total of 334 participants from six age groups (6–7-year-olds, 8–9-year-olds, 10–11-year-olds, 12–13-year-olds, 14–15-year-olds and adults) listened to a 30 second audio clip of an unfamiliar voice and were then presented with either a six person target-present or target-absent voice lineup. Overall, participants were more accurate with target-present than target-absent lineups. Moreover, performance on target-present lineups showed adult-like levels of attainment by 8–9 years of age. In contrast, performance on target-absent lineups was extremely poor, with all age groups tending to make a false identification. Confidence was higher when participants made correct rather than incorrect decisions for both types of lineup and this did not change with increasing age. Given these results, both child and adult earwitness evidence needs to be treated with considerable caution.     

Criminogenic needs and human needs: A theoretical model

Over the last two decades, empirical evidence has increasingly supported the view that it is possible to reduce reoffending rates by treating or rehabilitating offenders rather than simply punishing them. In fact, this shift from a punishment to a rehabilitation model is arguably one of the most significant events in modern correctional policy. Criminogenic needs, dynamic risk factors, have been the focus of a considerable amount of research and are viewed as primary intervention targets. Drawing from the correctional, psychological, philosophical, and social policy literature, we distinguish between instrumental and categorical needs. The latter are derived from assumptions about human nature and provide the theoretical grounds for the former, as well as for criminogenic needs. We argue that an enriched concept of needs embedded in the notion of human well being, can provide a coherent conceptual basis for rehabilitation and also avoid the problems apparent in the concept of criminogenic needs. From this perspective, criminogenic needs are usefully construed as the internal and external obstacles associated with need distortion. Therefore, they are directly linked to basic need distortion and the absence of the internal and external conditions necessary for a person to lead a fulfilling life. Finally, we outline a possible framework utilising categorical needs and discuss the clinical and policy implications of our perspective.     

Using Social Science to Inform the Law of Intestacy: The Case of Unmarried Committed Partners

Laws of intestate succession determine how the estate of a person who dies without a will is distributed. Researchers have struggled with the question of how to infer the donative intent of persons who die intestate. Based on an empirical study of unmarried committed partners, we compare the usefulness of two methods of social research for informing intestacy law: will studies and interviews with living persons about their preferences for estate distribution. The results indicate that for some groups of unmarried committed partners, will studies may not adequately reflect the extent to which intestate decedents wish their partner to share in their estate. In addition, the results demonstrate a close correspondence between respondents' actual wills, when they had them, and their distributive preferences on hypothetical scenarios. These findings are discussed as they relate to an examination of which sources of social scientific evidence are most useful in informing the law of intestacy.     

Missing persons-missing data: the need to collect antemortem dental records of missing persons

The subject of missing persons is of great concern to the community with numerous associated emotional, financial, and health costs. This paper examines the forensic medical issues raised by the delayed identification of individuals classified as "missing" and highlights the importance of including dental data in the investigation of missing persons. Focusing on Australia, the current approaches employed in missing persons investigations are outlined. Of particular significance is the fact that each of the eight Australian states and territories has its own Missing Persons Unit that operates within distinct state and territory legislation. Consequently, there is a lack of uniformity within Australia about the legal and procedural framework within which investigations of missing persons are conducted, and the interaction of that framework with coronial law procedures. One of the main investigative problems in missing persons investigations is the lack of forensic medical, particularly, odontological input. Forensic odontology has been employed in numerous cases in Australia where identity is unknown or uncertain because of remains being skeletonized, incinerated, or partly burnt. The routine employment of the forensic odontologist to assist in missing person inquiries, has however, been ignored. The failure to routinely employ forensic odontology in missing persons inquiries has resulted in numerous delays in identification. Three Australian cases are presented where the investigation of individuals whose identity was uncertain or unknown was prolonged due to the failure to utilize the appropriate (and available) dental resources. In light of the outcomes of these cases, we suggest that a national missing persons dental records database be established for future missing persons investigations. Such a database could be easily managed between a coronial system and a forensic medical institute. In Australia, a national missing persons dental records database could be incorporated into the National Coroners Information System (NCIS) managed, on behalf of Australia's Coroners, by the Victorian Institute of Forensic Medicine. The existence of the NCIS would ensure operational collaboration in the implementation of the system and cost savings to Australian policing agencies involved in missing person inquiries. The implementation of such a database would facilitate timely and efficient reconciliation of clinical and postmortem dental records and have subsequent social and financial benefits.     

Deterrence: A Panel Analysis

Recently, two research groups have tested the deterrence model using longitudinal designs (Saltzman, et al. 1982; Minor and Harry 1982). They suggest that most cross-sectional survey research on deterrence is so methodologically flawed as to be arguably irrelevant. Moreover, using a research strategy which is clearly more appropriate to test the model, they uncover no evidence of deterrent effects. This paper represents a partial replication and extension of these studies, using two-wave panel data from a sample of 2,147 adolescents. Unlike the prior panel research, the findings here support the viability of the deterrence model. They also indicate that there are significant differences in responsiveness to the perceived threat of sanctioning in terms of sociodemographic characteristics of potential offenders. The methodological and theoretical implications of the research are discussed.     

Location,location, location: Interdistrict and intercircuit variation in sentencing outcomes for federal drug-trafficking offenses

Research on sentencing has made clear that factors beyond case and offenders' attributes influence court decisions. Environmental and procedural characteristics also significantly affect the sentences of criminal courts. Yet, while state-level studies regularly control for such factors, most research on modern federal determinate sentencing has neglected jurisdictional attributes and variation as sources of extralegal sentence disparity. Using the organizational context and social worlds theoretical perspectives with a multilevel analytical approach, this study assessed how district and circuit of adjudication affect case-level lengths of sentences for federal drug-trafficking offenses, finding that both significantly affect sentencing outcomes and their predictors.     

Youths who sexually harm: A multivariate model of behaviour

Abstract

This study investigates the variations in behaviour displayed by young people who sexually harm, as previous research has shown that they are not a homogeneous sample. Three conceptually distinct sets of behaviour were hypothesized, relating to various modes of interaction between the young people with harmful sexual behaviour (HSB) and their victim, victim as object, victim as person and victim as vehicle. Thirty-three behaviours were drawn from an extensive review of the files of 300 youths who had sexually harmed. The pattern of co-occurrence of the presence or absence of these behaviours was revealed by a multidimensional scaling procedure, Smallest Space Analysis (SSA). The results provide empirical support for three distinct behavioural themes; 258 (86%) of the youths could be assigned to one dominant mode of interaction (victim as object, victim as person or victim as vehicle). The findings have implications for the ways in which practitioners differentiate between young people with HSB.     

Criminal thinking as a moderator of the perceived certainty–offending relationship: age variations

ABSTRACT

The purpose of this study was to determine whether the perceived certainty of punishment and general criminal thinking interact and whether the effect varies as a function of age. Data from all 1354 members (1170 males, 184 females) of the Pathways to Desistance study were used to test whether perceived certainty, general criminal thinking, and their interaction predicted subsequent offending during late adolescence (16–18 years of age) and emerging adulthood (20–22 years of age). The results showed that while perceived certainty and general criminal thinking failed to interact at age 17, general criminal thinking moderated the effect of perceived certainty at age 21. During emerging adulthood, offending was more common and varied in young adults with low certainty perceptions and high criminal thinking than it was in emerging adults with high criminal thinking and high certainty perceptions or low criminal thinking and either high or low certainty perceptions.     

Clinical assessment of adult sexual offenders with learning disabilities

Abstract

Assessment and treatment of adults with learning disabilities who commit sexual offences presents a number of challenges. Much of the professional forensic and psychiatric literature on work with this group concentrates on the development of interventions based on theoretical models of sexual offending originating from the mainstream criminal justice system and have often been adapted and applied to people with learning disabilities. Currently, there is very little evidence to demonstrate the effectiveness or validity of the adaptation and application of mainstream models to this population. The efficacy of such adapted models used to describe sexual offending in people with learning disabilities clearly has an impact of any intervention informed by them. In particular, some researchers suggest that key factors such as cognitive distortions are evident in sexual offenders with learning disabilities; there is, however, no research relating to the prevalence of these or other key factors within the general population of people with learning disabilities. The present literature review highlights some of the clinical issues with a particular focus on the assessment of deviant sexual interest. Specifically, the literature is confused with inconsistencies relating to the definition of the group, the extent and nature of offending and a lack of standardized methodology for assessment and comparison. Consideration is given to the particular needs of this group and the implications for research and treatment.
