Cognition and psychopathy in incarcerated sexual offenders / Cognição e psicopatia em autores de violência sexual encarcerados

Objective: The objective was to investigate if perpetrators of sexual offenses against children and adolescents with and without psychopathy differ regarding cognitive aspects. Method: A total of 30 male inmates participated in the study, divided into two groups: one that included psychopaths and the other with non-psychopaths. The instruments used were: protocol for collecting information on criminal court records; Rorschach test according to the Performance Assessment System, considering the cognitive variables and the Psychopathy Checklist-Revised Scale. Results: The results indicate that psychopaths exhibit greater impairment in the organization of thoughts, as well as greater vulnerability to the general personality disruption. The best regression model showed that 55% of psychopathy can be explained by a greater propensity to a general personality disorder (EII-3 β: 4.77; p-value < 0.001), associated with the predisposition to be arrested at a young age (β: -0.26; p-value = 0.004). Conclusion: The efficiency of the R-PAS is observed in the identification of cognitive failures in psychopath perpetrators of sexual violence and perpetrators of sexual violence, and its usefulness is enhanced, when associated with other behavioral measures in the identification of this type of personality profile.

Objetivo: O objetivo foi investigar se autores de violência sexual contra crianças e adolescentes, com e sem psicopatia, se diferenciam em relação aos aspectos cognitivos. Método: Participaram do estudo 30 reeducandos cumprindo pena em regime fechado, divididos em dois grupos: um composto pelos psicopatas e outro pelos não psicopatas. Os instrumentos utilizados foram: protocolo de coleta de informações no processo criminal; teste de Rorschach, de acordo com o Sistema de Avaliação por Performance, considerando as variáveis cognitivas, e; a escala Psychopathy Checklist-Revised. Resultados: Os resultados indicaram que o grupo de psicopatas apresentou maiores prejuízos na organização do pensamento, bem como maior vulnerabilidade à desorganização geral da personalidade. O melhor modelo de regressão identificou que 55% da psicopatia pode ser explicada por uma maior propensão ao desajuste geral da personalidade (EII-3 β: 4.77; p-value < 0.001), associada à predisposição a ser preso ainda jovem (β: -0.26; p-value = 0.004). Conclusão: A eficiência do R-PAS é observada na identificação de falhas cognitivas em psicopatas autores de violência sexual e autores de violência sexual, e sua utilidade é potencializada, quando associada a outras medidas comportamentais na identificação desse tipo de perfil de personalidade.

Combining Wake-Up-Back-to-Bed with Cognitive Induction Techniques: Does Earlier Sleep Interruption Reduce Lucid Dream Induction Rate?

Lucid dreaming offers the chance to investigate dreams from within a dream and by real-time dialogue between experimenters and dreamers during REM sleep. This state of consciousness opens a new experimental venue for dream research. However, laboratory study in this field is limited due to the rarity of lucid dreamers. In a previous study, we were able to induce in 50% of the participants a lucid dream in a single sleep laboratory night by combining a wake-up-back-to-bed (WBTB) sleep routine and a mnemonic method (Mnemonic Induction of Lucid Dreams, MILD). In three experiments, we tried to replicate our earlier findings while we adapted our procedure in shortening (Exp1-3: 4.5 vs. 6 h of uninterrupted sleep in the first half of the night), simplifying (Exp2: time-based wakening vs. REM wakening in the second half of the night), and applying another induction technique (Exp3: reality testing vs. MILD). In the three conditions, four out of 15 (26%), zero out of 20 (0%), and three out of 15 (20%) participants reported a lucid dream. Compared to the original study, the earlier sleep interruption seems to reduce the lucid dream induction rate. Furthermore, without REM awakenings in the morning, lucid dream induction failed, whereas reality testing showed a lower success rate compared to MILD. Further systematic sleep laboratory studies are needed to develop reliable techniques for lucid dream research.

Training-Dependent Change in Content of Association in Appetitive Pavlovian Conditioning.

In appetitive Pavlovian conditioning, experience with a conditional relationship between a cue [conditioned stimulus (CS)] and a reward [unconditioned stimulus (US)] bestows CS with the ability to promote adaptive behavior patterns. Different features of US (e.g., identity-specific sensory, general motivational) can be encoded by CS based on the nature of the CS-US relationship experienced (e.g., temporal factors such as training amount) and the content of association may determine the influence of CS over behavior (e.g., mediated learning, conditioned reinforcement). The content of association changed with varying conditioning factors, thereby altering behavioral consequences, however, has never been addressed in relevant brain signals evoked by CS. Our previous study found that phospholipase C ß1-knockout (PLCß1-KO) mice display persistent mediated learning over the extended course of odor-sugar conditioning, and that wild-type (WT) mice lose mediated learning sensitivity after extended training. In this study, in order to see whether this behavioral difference between these two genotypes comes from a difference in the course of association content, we examined whether odor CS can evoke the taste sensory representation of an absent sugar US after minimal- and extended training in these mice. In contrast to WT, which lost CS-evoked neural activation (c-Fos expression) in the gustatory cortex after extended training, KO mice displayed persistent association with the sensory feature of sugar, suggesting that sensory encoding is reliably linked to mediated learning sensitivity and there is a training-dependent change in the content of association in WT. PLCß1 knockdown in the left medial prefrontal cortex (mPFC) resulted in mediated learning sensitivity and CS-evoked gustatory cortical activation after extended training, proposing a molecular component of the neural system underlying this Pavlovian conditioning process. We also discuss how disruption of this process is implicated for hallucination-like behaviors (impaired reality testing).

A Proposed Probabilistic Method for Distinguishing Between Delusions and Other Environmental Judgements, With Applications to Psychotherapy.

How can individuals with schizophrenia best be equipped to distinguish delusions from accurate judgements about their environment? This study presents an approach based on the principles of Bayesian probability and presents the results of a series of tests in which a simulated observer classifies randomly generated data characteristic of a simulated environment. The complexity of the data ranges from scalars to vectors of variable lengths, and the simulated observer makes its decisions based on either perfect or imperfect models of its environment. We find that when a low-dimensional observation is considered characteristic of both real observations and delusions, the prior probabilities of any observation being real or fake are of greater importance to the final decision than the attributes of the observation. However, when an observation is high-dimensional (complex), classification accuracy tends to improve toward 100% with increasing complexity of observations, as long as the patient's model of the world isn't drastically inaccurate. On the contrary, when the observer's model is sufficiently inaccurate, the accuracy rate decreases with increasing observational complexity. Overall, the results suggest applicability of the Bayesian model to the use of interventional therapy for those who suffer from psychosis.

Paranormal Belief, Thinking Style and Delusion Formation: A Latent Profile Analysis of Within-Individual Variations in Experience-Based Paranormal Facets.

This study examined the degree to which within-individual variations in paranormal experience were related to belief in the paranormal, preferential thinking style, and delusion formation. A sample of 956 non-clinical adults completed measures assessing experience-based paranormal indices (i.e., paranormal experience, paranormal practitioner visiting, and paranormal ability), paranormal belief, belief in science, proneness to reality testing deficits, and emotion-based reasoning. Latent profile analysis (LPA) combined the experience-based indices to produce six underlying groups. Inter-class comparison via multivariate analysis of variance (MANOVA) indicated that both breadth and intensity of experiential factors were associated with higher belief in in the paranormal, increased proneness to reality testing deficits, and greater emotion-based reasoning. Belief in science, however, was less susceptible to experiential variations. Further analysis of reality testing subscales revealed that experiential profiles influenced levels of intrapsychic activity in subtle and intricate ways, especially those indexing Auditory and Visual Hallucinations and Delusional Thinking. Collectively, identification of profiles and inter-class comparisons provided a sophisticated understanding of the relative contribution of experiential factors to differences in paranormal belief, belief in science, proneness to reality testing deficits, and emotion-based reasoning.

Differences in Cognitive-Perceptual Factors Arising From Variations in Self-Professed Paranormal Ability.

This study examined whether scores on indices related to subclinical delusion formation and thinking style varied as a function of level of self-professed paranormal ability. To assess this, the researchers compared three groups differing in personal ascription of paranormal powers: no ability, self-professed ability, and paranormal practitioners (i.e., Mediums, Psychics, Spiritualists, and Fortune-Tellers). Paranormal practitioners (compared with no and self-professed ability conditions) were expected to score higher on paranormal belief, proneness to reality testing deficits, emotion-based reasoning, and lower on belief in science. Comparable differences were predicted between the self-professed and no ability conditions. A sample of 917 respondents (329 males, 588 females) completed self-report measures online. Multivariate analysis of variance (MANOVA) revealed an overall main effect. Further investigation, using discriminant descriptive analysis, indicated that paranormal practitioners scored higher on proneness to reality testing deficits, paranormal belief, and emotion-based reasoning. Belief in science did not meaningfully contribute to the discriminant function. Overall, results were consistent with previous academic work in the domains of paranormal belief and experience, which has reported that paranormal-related cognitions and perceptions are associated with factors related to subclinical delusion formation (i.e., emotion-based/intuitive thinking).

Associations among parental and romantic attachment, personality disorder symptoms, and physical health.

The relations of parental and romantic attachment with physical health symptoms and the mediating role of personality disorder symptoms in those relations were examined in an online survey of US young adults. Latent class analysis identified two groups: occasionally sick and healthier. Insecure attachment was related to being occasionally sick and to personality disorder symptoms (poor reality testing, primitive defenses, and diffused identity). Primitive defenses/identity diffusion mediated relations between insecure parental attachment and physical symptoms. Maternal and paternal attachment each provided unique information about these relations. Romantic attachment was not associated with physical symptoms after adjusting for parental attachment and personality disorder symptoms.

Inducing lucid dreams by olfactory-cued reactivation of reality testing during early-morning sleep: A proof of concept.

The reliable induction of lucid dreams is a challenge in lucid dream research. In a previous study by our research group we were able to induce in about 50% of the participants a lucid dream in a single sleep laboratory night by combining a wake-up-back-to-bed sleep protocol and a mnemonic technique. In the present study, we extended our previous procedure by additional presentation of an odor during sleep to reactivate memory traces about reality testing. In total 16 male participants spent a single night in the sleep lab whereas the procedure induced in two participants a lucid dream (12.5%). The induction rate stays below the success rate of our previous study and therefore odor-cueing seems not a promising technique for inducing lucid dreams. Beside the odor presentation, several other methodological changes have been made, which will be discussed and hopefully help further dream engineering to improve induction techniques.

Lucid Dreaming, Nightmares, and Sleep Paralysis: Associations With Reality Testing Deficits and Paranormal Experience/Belief.

Focusing on lucid dreaming, this paper examined relationships between dissociated experiences related to rapid eye movement (REM) sleep (lucid dreaming, nightmares, and sleep paralysis), reality testing, and paranormal experiences/beliefs. The study comprised a UK-based online sample of 455 respondents (110 males, 345 females, Mean age = 34.46 years, SD = 15.70), who had all previously experienced lucid dreaming. Respondents completed established self-report measures assessing control within lucid dreaming, experience and frequency of nightmares, incidence of sleep paralysis, proneness to reality testing deficits (Inventory of Personality Organization subscale, IPO-RT), subjective experience of receptive psi and life after death (paranormal experience), and paranormal belief. Analysis comprised tests of correlational and predictive relationships between sleep-related outcomes, IPO-RT scores, and paranormal measures. Significant positive correlations between sleep and paranormal measures were weak. Paranormal measures related differentially to sleep indices. Paranormal experience correlated with lucid dreaming, nightmares, and sleep paralysis, whereas paranormal belief related only to nightmares and sleep paralysis. IPO-RT correlated positively with all paranormal and sleep-related measures. Within the IPO-RT, the Auditory and Visual Hallucinations sub-factor demonstrated the strongest positive associations with sleep measures. Structural equation modeling indicated that Auditory and Visual Hallucinations significantly positively predicted dissociated experiences related to REM sleep, while paranormal experience did not. However, paranormal experience was a significant predictor when analysis controlled for Auditory and Visual Hallucinations. The moderate positive association between these variables explained this effect. Findings indicated that self-generated, productive cognitive-processes (as encompassed by Auditory and Visual Hallucinations) played a significant role in conscious control and awareness of lucid dreaming, and related dissociative sleep states (sleep paralysis and nightmares).

An Evaluation of the Belief in Science Scale.

The Belief in Science Scale (BISS) is a unidimensional measure that assesses the degree to which science is valued as a source of superior knowledge. Due to increased academic interest in the concept of belief in science, the BISS has emerged as an important measurement instrument. Noting an absence of validation evidence, the present paper, via two studies, evaluated the scale's factorial structure. Both studies drew on data collected from previous research. Study 1 (N = 686), using parallel analysis and exploratory factor analysis, identified a unidimensional solution accounting for 56.43% of the observed variance. Study 2 (N = 535), using an independent sample, tested the unidimensional solution using confirmatory factor analysis (CFA). Data-model fit was good (marginal for RMSEA): CFI = 0.93, TLI = 0.91, RMSEA = 0.09 (90% CI of 0.08 to 0.10), SRMR = 0.04. Invariance testing across gender supported invariance of form, factor structure, and item intercepts for this one-factor model. BISS at the overall level correlated negatively with the reality testing dimension of the Inventory of Personality Organization (IPO-RT), demonstrating convergent validity. Researchers often use the IPO-RT as an indirect index of preference for experiential processing (intuitive thinking). In this context, only BISS scores above the median (second quartile) produced a reduction in experiential-based thinking. The authors discuss these findings in the context of belief in science as a psychometric construct.

Psychotic Personality Structure.

This article discusses the concept of psychotic personality organization. I relate psychotic personality organization to observations and speculations about psychotic transferences and to behavioral developments during the treatment of chronically psychotic patients (particularly those with schizophrenia). The overwhelming theoretical perspectives used are twofold: (1) object relations theory and (2) a model integrating neurobiological advances in the study of psychosis with contemporary psychodynamic perspectives.

A realidade da perda: considerações sobre o luto e o exame de realidade / The reality of loss: considerations on grief and reality testing / La realidad de la pérdida: consideraciones sobre el luto y el examen de la realidad

O objetivo deste ensaio é desdobrar a afirmação de Freud segundo a qual o trabalho psíquico do luto é iniciado a partir da constatação da realidade da perda objetal por meio da ação do exame (ou teste) de realidade. A discussão deste problema leva os autores a propor uma definição de "exame de atualidade", tendo em conta a formação da capacidade de distinguir a separação da perda. A reflexão a propósito desta distinção tem por consequência, ainda, a postulação de uma condição anterior à capacidade de vivenciar a perda objetal: o estado de perdição. Conclui-se que as construções desenvolvidas neste artigo podem auxiliar no entendimento: de certas características relacionais de pacientes que se enquadram nos chamados "estados-limites"; e do lugar que o luto ocupa na cultura contemporânea.

This essay aims to unfold Freud's statement that the psychic elaboration of grief begins upon the realization of the loss of an object through the act of reality testing. While discussing this problem, the authors propose a definition of "immediacy testing" considering the development of the capacity to distinguish separation from loss. From this distinction, they postulate, also, a prior condition to the ability to experience an object's loss: the "state of perdition". It is concluded that the constructions undertaken in this article can help in the understanding of: certain relational characteristics of patients fitting so-called "borderline states"; and the place taken by the experience of grief in today's culture.

El objetivo de este ensayo es explorar la afirmación de Freud según la cual el trabajo psíquico del luto empieza con la constatación de la realidad de la pérdida objetal por medio de la acción del examen de la realidad. La discusión acerca de este problema lleva los autores a proponer una definición de "examen de la actualidad", llevando en cuenta la formación de la capacidad de distinguir entre la separación y la pérdida. Reflejar sobre esta distinción tiene por consecuencia, además, la postulación de una condición anterior a la capacidad de vivenciar la pérdida objetal: el "estado de perdición". Se concluye que las construcciones desarrolladas en este artículo pueden contribuir a la comprensión: de ciertas características relacionales de pacientes que se encajan en lo que se llama "estados-límites"; y del lugar que el luto ocupa en la cultura contemporánea.

Confirmatory Factor Analysis of the Inventory of Personality Organization-Reality Testing Subscale.

The reality testing dimension of the Inventory of Personality Organization, the IPO-RT, has emerged as an important index of proneness to reality testing deficits. However, to date few studies have examined the factorial structure of the IPO-RT in isolation. This is an important and necessary development because studies use the IPO-RT as a discrete measure. Additionally, psychometric evaluation of the IPO suggests alternative factorial solutions. Specifically, recent work supports multidimensionality, whereas initial IPO assessment evinced a unidimensional structure. Accordingly, this study, using a heterogeneous sample (N = 652), tested the fit of several factorial models (one-factor, four-factor oblique, second-order, and bifactor) via maximum likelihood with bootstrapping due to multivariate non-normality. Analysis revealed superior fit for the bifactor solution (correlated errors) (CFI = 0.965, SRMR = 0.036, RMSEA = 0.042). This model comprised a general reality testing dimension alongside four subfactors (auditory and visual hallucinations, delusional thinking, social deficits, and confusion). Inter-factor correlations were in the moderate range. Item loadings and omega reliability supported the notion that the IPO-RT emphasizes a single latent construct. The model demonstrated invariance across gender and partial age invariance. Overall, from a psychometric perspective, the IPO-RT functioned effectively at both global and, to an extent, factorial levels. Findings recommend that the IPO-RT should be scored as a total scale, and rather than treat subscales independently, future studies should consider examining factor variance alongside overall scale scores.

Representation-mediated Aversion as a Model to Study Psychotic-like States in Mice.

Several paradigms for rodent models of the cognitive and negative endophenotypes found in schizophrenic patients have been proposed. However, significant efforts are needed in order to study the pathophysiology of schizophrenia-related positive symptoms. Recently, it has been shown that these positive symptoms can be studied in rats by using representation-mediated learning. This learning measure the accuracy of mental representations of reality, also called 'reality testing'. Alterations in 'reality testing' performance can be an indication of an impairment in perception which is a clear hallmark of positive psychotic-like states. Thus, we describe here a mouse task adapted from previous findings based on a sensory preconditioning task. With this task, associations made between different neutral stimuli (e.g., an odor and a taste) and subsequent selective devaluation of one of these stimuli have allowed us to study mental sensory representations. Thus, the interest of this task is that it can be used to model positive psychotic-like states in mice, as recently described.

Perception of Risk and Terrorism-Related Behavior Change: Dual Influences of Probabilistic Reasoning and Reality Testing.

The present study assessed the degree to which probabilistic reasoning performance and thinking style influenced perception of risk and self-reported levels of terrorism-related behavior change. A sample of 263 respondents, recruited via convenience sampling, completed a series of measures comprising probabilistic reasoning tasks (perception of randomness, base rate, probability, and conjunction fallacy), the Reality Testing subscale of the Inventory of Personality Organization (IPO-RT), the Domain-Specific Risk-Taking Scale, and a terrorism-related behavior change scale. Structural equation modeling examined three progressive models. Firstly, the Independence Model assumed that probabilistic reasoning, perception of risk and reality testing independently predicted terrorism-related behavior change. Secondly, the Mediation Model supposed that probabilistic reasoning and reality testing correlated, and indirectly predicted terrorism-related behavior change through perception of risk. Lastly, the Dual-Influence Model proposed that probabilistic reasoning indirectly predicted terrorism-related behavior change via perception of risk, independent of reality testing. Results indicated that performance on probabilistic reasoning tasks most strongly predicted perception of risk, and preference for an intuitive thinking style (measured by the IPO-RT) best explained terrorism-related behavior change. The combination of perception of risk with probabilistic reasoning ability in the Dual-Influence Model enhanced the predictive power of the analytical-rational route, with conjunction fallacy having a significant indirect effect on terrorism-related behavior change via perception of risk. The Dual-Influence Model possessed superior fit and reported similar predictive relations between intuitive-experiential and analytical-rational routes and terrorism-related behavior change. The discussion critically examines these findings in relation to dual-processing frameworks. This includes considering the limitations of current operationalisations and recommendations for future research that align outcomes and subsequent work more closely to specific dual-process models.

Urban Legends and Paranormal Beliefs: The Role of Reality Testing and Schizotypy.

Recent research suggests that unconventional beliefs are locatable within a generic anomalous belief category. This notion derives from the observation that apparently dissimilar beliefs share fundamental, core characteristics (i.e., contradiction of orthodox scientific understanding of the universe and defiance of conventional understanding of reality). The present paper assessed the supposition that anomalous beliefs were conceptually similar and explicable via common psychological processes by comparing relationships between discrete beliefs [endorsement of urban legends (ULs) and belief in the paranormal] and cognitive-perceptual personality measures [proneness to reality testing (RT) and schizotypy]. A sample of 222 volunteers, recruited via convenience sampling, took part in the study. Participants completed a series of self-report measures (Urban Legends Questionnaire, Reality Testing subscale of the Inventory of Personality Organization, Revised Paranormal Belief Scale and the Schizotypal Personality Questionnaire Brief). Preliminary analysis revealed positive correlations between measures. Within schizotypy, the cognitive-perceptual factor was most strongly associated with anomalistic beliefs; disorganized and interpersonal produced only weak and negligible correlations respectively. Further investigation indicated complex relationships between RT, the cognitive-perceptual factor of schizotypy and anomalistic beliefs. Specifically, proneness to RT deficits explained a greater amount of variance in ULs, whilst schizotypy accounted for more variance in belief in the paranormal. Consideration of partial correlations supported these conclusions. The relationship between RT and ULs remained significant after controlling for the cognitive-perceptual factor. Contrastingly, the association between the cognitive-perceptual factor and ULs controlling for RT was non-significant. In the case of belief in the paranormal, controlling for proneness to RT reduced correlation size, but relationships remained significant. This study demonstrated that anomalistic beliefs vary in nature and composition. Findings indicated that generalized views of anomalistic beliefs provide only limited insight into the complex nature of belief.

Unconscious fantasy in context: The work of Jacob A. Arlow.

For Jacob A. Arlow, understanding unconscious fantasies was central to his clinical work. These fantasies are to be found at the core of those eruptions that break without warning into our ordinary lives, whether in the form of hysterical symptoms, daydreams or nightmares. What, however, could an unconscious fantasy be on a theoretical level, beyond a vehicle for discharge? Although partly unconscious, such fantasies are sometimes composed of fixed verbal content with a high degree of internal organisation. Unconscious fantasies therefore pose many challenges to understanding.

Relationship between the Rorschach Perceptual Thinking Index (PTI) and the Positive and Negative Syndrome Scale (PANSS) in psychotic patients: a validity study.

The aim of this study is to demonstrate the validity of the Rorschach Perceptual Thinking Index (PTI) in the assessment of reality testing in patients with psychosis. We evaluated the relationship between the PTI criteria and the Positive and Negative Syndrome Scale (PANSS) scores in 98 psychotic disorder affected patients. Thirty four were evaluated during the acute episode (AP) and 64 were chronically treated and stable (CP). The PANSS positive score resulted significantly higher in AP than in CP group, but no significant difference was found in the PTI score. The PTI positively correlated with the PANSS total score. The PTI1 and PTI2 criteria significantly correlated with the PANSS negative score, the PTI4 and PTI5 with the positive. The Rorschach variable X-% significantly correlated with the negative symptoms; the WSum6 with thought disorders; and the M- with delusions. PTI score, X-% and WSum6 predicted impaired judgment and insight. These results suggest that PTI is a valid instrument to assess impairment in reality testing, regardless of the patient׳s current psychiatric presentation. The presence of conceptual disorganization, delusions, lack of judgment and insight don׳t have effects on the PTI, supporting its strength as an assessment tool for psychotic disorders.

Mourning in the psychoanalytic situation and in Shakespeare's The Tempest.

Recognizing that mourning builds psychic structure, the author highlights the ubiquitous and essential nature of mourning in the psychoanalytic situation. Reality testing is intimately connected to mourning and is the warp on which psychic structure is woven in the analytic situation. Reality testing necessarily involves opportunities for mourning and thus will be present in every analytic hour. The confrontation with reality is the basis for all processes of mourning, or for creating defenses against this painful experience. The author views mourning as fundamentally a transformational process, and Shakespeare's The Tempest is used to illustrate this aspect of mourning.

A rare case of imitation injury.

The impact of media on cognitions and behaviors of adolescents is well-known. High frequency of exposure to media may distort the reality testing among predisposed youth, hence the rise in risk taking behaviors among this population. We present a rare manifestation of risk taking behavior in an adolescent who injected mercury in his body after exposure to a Hollywood film. The results of investigations and possible explanation to understand risk taking behavior in the present case are discussed.
