The controversy of defining serial murder: Revisited

Over the years, researchers and law enforcement professionals have tried to achieve uniformity in the use of the term “serial murder,” but such efforts have rather proved futile. Endeavors aimed at achieving a consensus on the definition of serial murder have potentiated its precarious applications. Though the term continues to remain elusive, ambiguous and amorphous in the literature, recent efforts are suggestive of a trend towards the attainment of a standardized definition of serial murder. However, a review of both current research and legal definitions of serial murder revealed some discrepancies in how the term is defined. Built upon Skrapec's (2001) definition, the current article aims to revisit several key definitional issues and to propose a more comprehensive serial murder definition with three key elements: (1) Two or more forensic linked murders with or without a revealed intention of committing additional murder, (2) the murders are committed as discrete event(s) by the same person(s) over a period of time, and (3) where the primary motive is personal gratification.     

Benefits of recreational dance and behavior analysis for individuals with neurodevelopmental disorders: A literature review

Dance can be an entertaining experience that offers multiple benefits for those who participate. Unlike typically developing populations, studies examining benefits of recreational dance for individuals with neurodevelopmental disorders are limited. In this review, we conducted a literature search, where “dance” was cross‐listed with all neurodevelopmental disorders across five databases, yielding 19 articles. Twelve studies involved children and youth with neurodevelopmental disorders aged 3–19 years, two studies included both adolescents and adults aged 14–22 years, and five studies included adults aged 20–65 years. Given the effectiveness of applied behavior analysis in enhancing skill development, it is encouraging that eight studies explicitly identified behavioral components. Results suggest potential benefits of recreational dance across studies using self‐report and objective measures, but limited research with sound methodology exists. There is a need for controlled research with measurable outcomes to evaluate programs tailored to these populations to improve core challenges and secondary outcomes such as quality of life.     

Infectious and immune factors in the pathogenesis of neurodevelopmental disorders: epidemiology, hypotheses, and animal models

Both genetic and environmental factors contribute to the pathogenesis of a wide variety of neurodevelopmental disorders, including autism, mental retardation, and schizophrenia. Some heritable disorders approach 100% penetrance; nonetheless, even in these disorders, subtle aspects of clinical disease expression may be influenced by the environment. In other disorders with genetic influences, exogenous factors, and the timepoint(s) during nervous system development at which they are introduced, modulate expression of disease. Elucidation of the mechanisms guiding this intricate interplay between host response genes, environmental agents, and the neurodevelopmental context within which these interactions occur, is necessary to understand the continuum of clinical outcomes. This chapter will review the evidence that infectious and immune factors may contribute to the pathogenesis of neurodevelopmental disorders, describe an animal model of neurodevelopmental disorders based upon viral infection, identify processes by which neural circuitry may be compromised, and outline areas for future research.     

Rethinking the concepts of ‘local or global processors’: evidence from Williams syndrome,Down syndrome,and Autism Spectrum Disorders

Both Williams syndrome (WS) and Autism Spectrum Disorder (ASD) have been characterized as preferentially processing local information, whereas in Down syndrome (DS) the reported tendency is to process stimuli globally. We designed a cross‐syndrome, cross‐task comparison to reveal similarities and differences in local/global processing in these disorders. Our in‐depth study compared local/global processing across modalities (auditory‐verbal/visuo‐spatial) and levels of processing (high/low) in the three syndromes. Despite claims in the literature, participants with ASD or WS failed to show a consistent local processing bias, while those with DS failed to show a reliable global processing bias. Depending on the nature of the stimuli and the task, both local and global processing biases were evident in all three neurodevelopmental disorders. These findings indicate that individuals with neurodevelopmental disorders cannot simply be characterized as local or global processors.     

Spatial patterns of serial murder: an analysis of disposal site location choice

Although the murders committed by serial killers may not be considered rational, there is growing evidence that the locations in which they commit their crimes may be guided by an implicit, if limited rationality. The hypothesized logic of disposal site choice of serial killers led to predictions that (a) their criminal domains would be around their home base and relate to familiar travel distances, (b) they would have a size that was characteristic of each offender, (c) the distribution would be biased towards other non-criminal activities, and (d) the size of the domains would increase over time. Examination of the geographical distribution of the sites at which 126 US and 29 UK serial killers disposed of their victims' bodies supported all four hypotheses. It was found that rational choice and routine activity models of criminal behavior could explain the spatial choices of serial murderers. It was concluded that the locations at which serial killers dispose of their victims' bodies reflect the inherent logic of the choices that underlie their predatory activities.     

Children's reactions to serial murder

This study examined the psychological reactions of children who lived in a community exposed to serial murder. The research also examined how parents coped with their children's psychological responses. Thirty-four parents of 64 children between the ages of 5 and 18, inclusive, were asked to identify changes in their children since the serial murders. Data collection began 4 weeks following the murders and included assessment of emotional, cognitive and behavioral aspects of the child's responses. Follow-up data collection occurred at 9 months and 18 months after the murders. Results indicated that children, as a group, experienced a number of psychological changes following the murders, even though none of the actual victims were children. The most frequently reported symptoms were anxiety-based (fear of being alone, difficulty falling asleep and wanting to sleep with patents). Most children showed a significant decline in symptoms across time. The most popular parent coping strategies involved discussing issues of risk minimization, talking about the murders, and spending more time with children.     

The Jack the Ripper murders: a modus operandi and signature analysis of the 1888–1891 Whitechapel murders

A number of females, commonly recognized as 11 victims, were murdered in separate events in Whitechapel, London between 1888 and 1891. An evaluation of the murders revealed that six of those murders were linked by a number of distinct, personal signature characteristics, including picquerism, overkill, incapacitation, domination and control, open and displayed, unusual body position, sexual degradation, mutilation, organ harvesting, specific areas of attack, preplanning and organization, and a combination of signature features. The signature characteristics observed in these infamous Jack the Ripper murders were compared to a 1981–1995 cohort of 3359 homicide cases from Washington State's HITS database. The analysis revealed that the signature displayed in six of the Whitechapel murders was extremely rare. There were only six records of female victims, one a prostitute, with probed, explored, or mutilated body cavities. There were only two cases, both females who were not prostitutes, where the body was left in an unusual position and body cavities were explored, probed, or mutilated.

What standardized tests ignore when assessing individuals with neurodevelopmental disorders / Lo que ignoran los tests estandarizados en la evaluación de personas con trastornos del neurodesarrollo

Abstract

In this article we critique the use of traditional standardized tests for the cognitive assessment of children with neurodevelopmental disorders. Limitations stem from the lack of integrating (a) results from research into the psychological functioning of these populations, and (b) the main arguments underlying models of human development. We identify four secondary issues in this discussion: (1) these instruments cannot be used with children who have particularly low cognitive functioning; (2) little or no variance in the scores obtained by individuals with neurodevelopmental disorders, because all are at floor, prevent adequate interpretations; (3) measurements do not provide information useful for the design of intervention strategies; and (4) different cognitive and/or neural processes may underlie behavioural scores ‘in the normal range’. Rethinking traditional assessment methods in favour of technologically-mediated games yields new cognitive assessment possibilities.     

Fear of future illness, chemical AIDS, and cancerphobia: a review.

A review of the literature indicates that fear of future illness shares many characteristics with a wide variety of conditions. Concepts such as hypochondriasis, adjustment disorders, generalized anxiety, and mass hysteria must be considered. Also, factors such as reporting bias, influential others, collective behavior, political groups, and litigation appear to induce symptom reporting from patients complaining of fear of illness and cancerphobia. Cancerphobia may result in impairment ranging from avoidance behaviors to cognitive dysfunctions. Various treatment modalities have been used successfully in treating cancerphobia, and the prognosis is typically good. Complaints of chemical AIDS, universal allergy, or twentieth century disease have little medical or empirical support and require further investigation. Researchers and clinicians must recognize multiple factors contribute to fear of future illness or cancerphobic complaints, and additional research must be undertaken if a thorough understanding of fear of future illness, cancerphobia, and perceptions of chemical AIDS is to be obtained.     

Mindfulness and emotional distress: The role of negatively biased cognition

Mindfulness is a receptive attention to and awareness of events and experiences as they occur. A substantial body of literature supports the usefulness of mindfulness-based approaches for preventing or reducing emotional distress (e.g., depression and anxiety). However, mechanisms by which mindfulness produces these benefits are still being explored. Cognitive theories of emotional disorder implicate negatively biased cognition as a primary source of distress, and the theoretical literature on mindfulness suggests that it may reduce biased thoughts and judgments. Thus, the present research tested a mediation model in which less negatively biased cognition explains the inverse relation between mindfulness and emotional distress. Participants completed multiple standardized measures of trait mindfulness, negatively biased cognition, and emotional distress. The proposed relations between these constructs then were examined using structural equation modeling. Support was found for a partial mediation model, and possible alternative models were ruled out. These findings highlight a previously unidentified cognitive mechanism to explain the relation between mindfulness and reduced emotional distress. Specifically, mindfulness may reduce negative, maladaptive cognitive styles, which in turn may reduce predisposition to emotional disorders.     

The neurodevelopmental frontostriatal disorders: evolutionary adaptiveness and anomalous lateralization

The frontostriatal system (dorsolateral prefrontal cortex, lateral orbitofrontal cortex, anterior cingulate, supplementary motor area, and associated basal-ganglia structures) is subject to a range of neurodevelopmental disorders: Tourette's syndrome (TS), obsessive compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), schizophrenia (SCZ), autism, and probably depression. The system is responsible for our adaptive responses (initiation, execution, or withholding) to environmental situations, and the above disorders, involving effectively excessive release or withholding of various types of response, are all a consequence of changes in specific frontostriatal regions. The disorders all have a genetic component, and their persistence in the genome indicates that their clinical manifestations may also be associated, perhaps in low levels in close relatives, with certain adaptive advantages in given situations. Thus autism is associated with computational careers, depression with literary creativity, SCZ with lateral thinking and the Odyssean personality, ADHD with an Ice-Age readiness to respond, OCD with a focused range of interests, and TS with competitive sports and jazz improvisation. The disorders are all highly comorbid, and which one predominantly manifests may depend on how the frontostriatal system happens to be compromised as a result of inherited genetic predispositions and environmental contingency. We review the adaptive nature of the various subclinical manifestations and the evidence for concomitant phenomena (possibly epiphenomena): alterations in structural, functional, and behavioral lateralization in each syndrome. Indeed it is not clear that altered lateralization in frontostriatal disorders of a neurodevelopmental origin generally has any adaptive significance; it may often simply serve as a marker for altered regulatory function of the frontostriatal system, alterations which in low genetic dosage or penetrance continue to play an adaptive role in clinically unaffected close relatives of probands, but which, in high dosage or penetrance in the probands themselves, are generally deleterious.     

Sex differences in prenatal epigenetic programming of stress pathways

Maternal stress experience is associated with neurodevelopmental disorders including schizophrenia and autism. Recent studies have examined mechanisms by which changes in the maternal milieu may be transmitted to the developing embryo and potentially translated into programming of the epigenome. Animal models of prenatal stress have identified important sex- and temporal-specific effects on offspring stress responsivity. As dysregulation of stress pathways is a common feature in most neuropsychiatric diseases, molecular and epigenetic analyses at the maternal-embryo interface, especially in the placenta, may provide unique insight into identifying much-needed predictive biomarkers. In addition, as most neurodevelopmental disorders present with a sex bias, examination of sex differences in the inheritance of phenotypic outcomes may pinpoint gene targets and specific windows of vulnerability in neurodevelopment, which have been disrupted. This review discusses the association and possible contributing mechanisms of prenatal stress in programming offspring stress pathway dysregulation and the importance of sex.     

Beyond the fragments of the two Victoires: A fictionalised and incomplete memoir of the two women murdered by Pierre Rivière – His sister and his mother

This paper focuses on gendered spaces in which Pierre Rivière carried out the murder of his mother, his sister and his brother. The archival work of Foucault et al. provides multiple accounts of these family murders, including the very evocative memoir written by Pierre Rivière himself in prison. The position and perspectives of the women in that text, particularly those in his immediate family, are obscured, being seen very much through the eyes of men in general, and Pierre and his father specifically. Here we attempt to cut through that obscuration with a reflexive feminist excavation of fragments from this parricide case. We borrow from multiple sources including historical literature on women at that time, changing laws relating to equality and freedom, literary ways of coming to know the perspective of another through writing, magical realist strategies fostered in arts-based social research, and therapeutic strategies for remembering traumatic events. From these Victoire and her daughter are brought to life in a womanist reading that makes Victoire's position both imaginable and supportable. Specific historical material is confined to footnotes, so maintaining its coherence whilst allowing the foregrounding of the various narratives (from the research process, from original testimonies, and from attempts to write into the spaces left by those testimonies).     

Rescue Fantasies in Homicide-Suicide*

ABSTRACT: Thirteen homicide-suicides, events in which an individual murders one or more persons and kills himself immediately afterward, were studied. Findings were presented in terms of the setting in which these events occurred, the relationship between perpetrator and victim, and the rationalizations produced by the perpetrators to explain their behavior. The results are interpreted to suggest that persons who commit homicide-suicide are acting out a three-party rescue fantasy in an attempt to resolve unbearable stress.     

Maternal pregnancy-specific anxiety is associated with child executive function at 6-9 years age

Because fetal brain development proceeds at an extremely rapid pace, early life experiences have the potential to alter the trajectory of neurodevelopment, which may increase susceptibility for developmental and neuropsychiatric disorders. There is evidence that prenatal maternal stress and anxiety, especially worries specifically related to being pregnant, influence neurodevelopmental outcomes. In the current prospective longitudinal study, we included 89 women for whom serial data were available for pregnancy-specific anxiety, state anxiety, and depression at 15, 19, 25, 31, and 37 weeks gestation. When the offspring from the target pregnancy were between 6 and 9 years of age, their executive function was assessed. High levels of mean maternal pregnancy-specific anxiety over the course of gestation were associated with lower inhibitory control in girls only and lower visuospatial working memory performance in boys and girls. Higher-state anxiety and depression also were associated with lower visuospatial working memory performance. However, neither state anxiety nor depression explained any additional variance after accounting for pregnancy-specific anxiety. The findings contribute to the literature supporting an association between pregnancy-specific anxiety and cognitive development and extend our knowledge about the persistence of this effect until middle childhood.     

Occupational Therapy Assessment of Neurodevelopmentally Disordered Children and Adolescents

ABSTRACT

Research suggests that many children and adolescents with neurodevelopmental disorders such as attention deficit hyperactivity disorder or Tourette syndrome exhibit neurological soft signs including sensory misperception. The parents of 52 children or adolescents, ages 6 to 16, entering the Neurodevelopmental Disorders Clinic at St Boniface General Hospital completed a structured questionnaire measuring sensory and motor systems. The questionnaire formed the basis of a semi-structured interview involving parent(s) and child or adolescent. Results suggested altered sensory and motor processing and indicated an increased sensory sensitivity regarding tactile, auditory, olfactury, gustatory and visual sensations. The literature regarding sensory defensiveness and neurodevelopmental systems is discussed in relation to the findings from the sample.     

The concept of leakage in threat assessment

Leakage in the context of threat assessment is the communication to a third party of an intent to do harm to a target. Third parties are usually other people, but the means of communication vary, and include letters, diaries, journals, blogs, videos on the internet, emails, voice mails, and other social media forms of transmission. Leakage is a type of warning behavior that typically infers a preoccupation with the target, and may signal the research, planning, and implementation of an attack. Nomothetic data suggest that leakage occurs in a majority of cases of attacks on and assassinations of public figures, adult mass murders, adolescent mass murders, and school or campus shootings: very low-frequency, but catastrophic acts of intended and targeted violence. Idiographic or case data illustrate the various permutations of leakage. We discuss the operational importance of the concept, place it in the context of other warning behaviors, emphasize the need for further research, and outline risk management strategies for the mitigation of such acts of violence in both law enforcement and clinical mental health settings.     

Brain imaging in neurogenetic conditions: realizing the potential of behavioral neurogenetics research

Behavioral neurogenetics research is a new method of scientific inquiry that focuses on investigation of neurodevelopmental dysfunction associated with specific genetic conditions. This research method provides a powerful tool for scientific inquiry into human gene-brain-behavior linkages that complements more traditional research approaches. In particular, the use of specific genetic conditions as models of common behavioral and cognitive disorders occurring in the general population can reveal insights into neurodevelopmental pathways that might otherwise be obscured or diluted when investigating more heterogeneous, behaviorally defined subject groups. In this paper, we review five genetic conditions that commonly give rise to identifiable neurodevelopmental and neuropsychiatric disability in children: fragile X syndrome, velo-cardio-facial syndrome, Williams syndrome, Turner syndrome, and Klinefelter syndrome. While emphasis is placed on describing the brain morphology associated with these conditions as revealed by neuroimaging studies, we also include information pertaining to molecular genetic, postmortem, and neurobehavioral investigations to illustrate how behavioral neurogenetics research can contribute to an improved understanding of brain disorders in childhood.
