Moreno Rojas Abstract Background: Psychopathy is proven to be an important forensic construct highly comorbid with substance use disorders. Expanding beyond the traditional dimensions of psychopathy a further delineation of the construct is needed for a better understanding of the many aspects of psychopathy and its relation to substance misuse. Methods: The present study examined 327 high-risk adolescents in six Dutch juvenile residential facilities, on alcohol abuse (The Alcohol Use Disorders Identification Test), cannabis abuse (The Cannabis Use Disorders Identification Test), anxiety sensitivity (The Substance Use Risk Profile Scale), attentional bias (Visual Probe Task), and psychopathic traits (Youth Psychopathic traits Inventory). Results: Cluster analysis revealed that the construct of psychopathy is heterogeneous and that high-anxious secondary variants of psychopathic youth endorse more negative emotionality than low-anxious primary subtypes. The subtypes of juvenile psychopathy differed in their substance use, but contrary to expectations the primary subtype reported more substance use. As for attentional bias no significant differences between groups were found, although the secondary subtype displayed on average more attentional bias. Conclusions: Results further underline the possibility that the two variants of psychopathy, both of which are high on the affective-interpersonal dimensions of psychopathy, may have different developmental pathways, with the primary being more related to drug (ab)use and the secondary being more related to negative emotionality and attentional bias. Keywords: juvenile primary & secondary psychopathy, substance abuse, attentional bias 1. Introduction The development of delinquent behaviour is characterized by a great heterogeneity within youth who show serious antisocial behaviours (Skeem, Poythress, Edens, Lilienfeld, & Cale, 2003). Distinct groups differ not only on the life course and the severity of the displayed antisocial behaviour, but also on the likely causal processes leading to their antisocial behaviour (Frick & Viding, 2009). As a result, specifying methods for distinguishing among the different subgroups of antisocial individuals, and specifically distinguishing their developmental trajectories of antisocial behaviour, has attracted much interest. Rather than solely focusing on the behavioural outcomes and following the principle of equifinality (multiple aetiological/developmental pathways can lead to similar outcomes), a more thorough understanding of antisocial behaviour in youth is likely to result from studying the various developmental pathways that lead to delinquent behaviour (Kotler & McMahon, 2005). In this context, there has been an increasing interest in exploring psychopathic traits in juvenile populations, in particular because the presence or absence of these traits may help to identify unique aetiological pathways in the development of criminal behaviour and other negative outcomes. 4 Primary and secondary subtypes of juvenile psychopathy: a difference in attentional bias toward addictive substances 1.1 Juvenile Psychopathy Historically, psychopathy has been described as a stable personality disposition, which can be identified by a cluster of specific interpersonal, affective and antisocial traits and behaviours (Hare & Neumann, 2003). On the interpersonal level, psychopathic individuals display glibness/superficial charm, a grandiose sense of self worth, pathological lying and conning/manipulative behaviour. Affectively, they are characterized by a lack of remorse or guilt, callous/lack of empathy and shallow affect. Both the interpersonal and the affective dimension are closely related to a socially deviant lifestyle that includes a parasitic lifestyle, poor behavioural control, lack of realistic, long-term goals, impulsivity, irresponsibility, failure to accept responsibility for own actions and criminal versatility (Hare & Neumann, 2009). Several factors have led to an increasing interest in the topic of child and adolescent psychopathy. First, psychopathic traits have been strongly associated with aggressive and criminal behaviour in adult populations. This association has prompted interest in whether aggression, antisocial behaviour and violence in high-risk youth might be explained by similar personality correlates (Perez, 2012; Asscher et al., 2011). Second, due to the negative outcomes associated with psychopathy and the pessimistic view that psychopathy in adulthood seems to be unmalleable by treatment, the early identification of these particular traits seem to be essential (Rosenbaum, Lee, & Lester, 2009; Shine & Hobson, 2000; see Salekin (2002) for a meta-analysis challenging the notion that psychopathic offenders are untreatable). Moreover, retrospective findings point to the notion that psychopathic individuals have antisocial and criminal histories that commence prior to adulthood (Lynam, Miller, Vachon, Loeber, Stouthamer- Loeber, 2009; Salekin, 2008). In consequence, it is implicitly postulated that psychopathic traits in childhood or adolescence are related to adult psychopathy. However,

A. T. P1, Sakkeel. K. P2 ABSTRACT: Lying is a part of communication and a form of social behavior which is involved in interacting with others. Lying means saying a statement that he/she knows themselves as false to others to whom he/she want to perceive it as true. It can be explained by different psychological principles of psychodynamic theory, humanistic theory, behavior theory etc. Lying arises from hedonistic nature of humans that to avoid pain and to increase pleasure. It can be also seen that we lies not only for personal gains but also for others gain too. That is to avoid harm affecting ourselves and to avoid hurting others. Lying can be accepted if it saves someone’s life-ourselves or of others. Keywords: Psychological factors, Lie INTRODUCTION: Lying is a form of deceiving others verbally. It is a part of our behavioral response in communicating with others. It has long been a part of everyday life. We can't get through even a single day without telling lies. It is a consistent feature of human social behavior. We are not aware of all the lies we tell. We people lie most the time in our daily life, afraid of other people finding out the truth about us. We lie mostly to our parents, partners, friends, supervisors and so on to whomever else with whom we interact.

Here, we performed the largest diffusion tensor imag- ing (DTI) study of incarcerated criminal offenders to date (N 5 147) to determine whether psychopa- thy severity is linked to the microstructural integrity of major white matter tracts in the brain. Consistent with the results of previous studies in smaller samples, we found that psychopathy was associated with reduced fractional anisotropy in the right uncinate fasciculus (UF; the major white matter tract connecting ventral frontal and anterior temporal cortices). We found no such associa- tion in the left UF or in adjacent frontal or temporal white matter tracts. Moreover, the right UF finding was specifically related to the interpersonal features of psychopathy (glib superficial charm, grandiose sense of self-worth, pathological lying, manipulativeness), rather than the affective, anti- social, or lifestyle features.

  • Introduction Psychopathy and Substance Addiction Are Highly Co
    1 Introduction Psychopathy and substance addiction are highly co-morbid. This co-morbidity has often been examined in a cause and effect relationship, where one condition pre-dates the other and results in the onset of the second condition. Rather than view the co-morbidity between addiction and psychopathy as a cause and effect relationship, I will argue that the two disorders are actually linked by a series of underlying traits. These traits do not serve as simply common characteristics among addicts and psychopaths, but rather as an explanation for the emergence of both addictive and psychopathic behaviors in certain individuals. In examining the presence of impulsivity and novelty seeking in both addicts and psychopaths, these characteristics emerge as hallmark traits in both populations. Recent evidence suggests that both these traits may result from the presence of a specific polymorphism on the dopamine D4 receptor gene. This 7-repeat sequence on the dopamine D4 receptor gene may ultimately account for a pre-disposed, genetic vulnerability for the emergence of psychopathy and addictions as the result of increased impulsivity and novelty seeking coupled with negative environmental factors. History of Psychopathy Throughout history, societal norms define normal behavior. Defining and understanding normalcy has not been nearly as difficult as understanding the abnormal. The extremes of society present a struggle for explaining human behavior. While both the exceptionally good and terribly evil fall outside the realm of most human experiences, societies have always been fascinated with attempting to understand the extremes of behavior perceived as evil. 2 Psychopathy as a modern construct for understanding the behaviors and expressions which characterize the most evil extremes of society has largely been defined by the work of Robert Hare, who not only developed the defining list of psychopathic traits, but also created the Psychopathy Checklist, Revised for psychopathic evaluation (Hare online).

Despite scientific evidence supporting the existence of individual differences in lying, a validated measure of dispositional deception is still lacking. This study aims to explore the structure of dispositional deception by validating a 16-item questionnaire to characterize individuals’ lying patterns. The final sample included 716 participants (Mean age = 25.02; 55.87% females) who were recruited via posters, flyers, and online social media platforms in Singapore. Our findings suggested four distinct latent dimensions: frequency, ability, nega- tivity, and contextuality. We established the convergent validity of our measure by showing significant relationships with social desirability, malevolent traits, cognitive control deficits, normal and pathological personality traits, as well as demographic variables such as sex, age, and religiosity. Overall, the present study introduced a general framework to understanding deception as a dispositional trait.

    Alzheimer’s Disease Pathology as a Clue to Pathogenesis DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Kristen E. Funk Graduate Program in Molecular, Cellular and Developmental Biology The Ohio State University 2012 Dissertation Committee: Jeffrey A. Kuret, PhD, Advisor Christopher J. Phiel, PhD David E. Somers, PhD Mariano S. Viapiano, PhD Copyright by Kristen E. Funk 2012 Abstract Alzheimer’s disease is characterized pathologically by two intracellular lesions, granulovacuolar degeneration and neurofibrillary tangles. Because Alzheimer’s disease is primarily sporadic, the traditional starting point for studying disease is pathology. It is still debated whether these hallmark lesions are markers or mediators of disease progression; however, the correlation between these lesions and disease progression warrants their use as clues to underlying disease processes. The molecular mechanisms of their development, their role in the disease process, and their connection to one another are not fully understood. Granulovacuolar degeneration involves the accumulation of large, double membrane-bound bodies within certain neurons during the course of disease. Because of their ultrastructure, it is hypothesized that the bodies are autophagic. To test this, colocalization of autophagic and endocytic markers with a marker for granulovacuolar degeneration was investigated in hippocampal sections prepared from post mortem late stage Alzheimer’s
