The etiology of psychopathy: A neuropsychological perspective

While there is no universally accepted cause of psychopathy, there are basic biological patterns in brain dysfunction observed in individuals who display psychopathic tendencies. These individuals show significant impairment in specific regions of the brain, particularly the orbital frontal cortex (OFC). Such abnormalities exist in brain areas most involved in impulse control and behavior inhibition. There are also significant environmental factors that the majority of these individuals have in common. For example, a strong correlation exists between attachment disorder and anti-social personality disorder (ASPD). Finally, the differences between ASPD, psychopathy, and sociopathy are considered. While these terms are often used interchangeably, there are clear differences between these psychopathologies.     

Error monitoring dysfunction across the illness course of schizophrenia

Response monitoring abnormalities have been reported in chronic schizophrenia patients, but it is unknown whether they predate the onset of psychosis, are present in early stages of illness, or are late-developing abnormalities associated with illness progression. Response-synchronized event-related potentials (ERP) recorded during a picture-word matching task yielded error-related negativity (ERN), correct-response negativity (CRN), and error positivity (Pe) from 84 schizophrenia patients (SZ), 48 clinical high risk patients (CHR), and their age-matched healthy controls (HC; n = 110 and 88, respectively). A sub-sample of 35 early illness schizophrenia patients (ESZ) was compared to 93 age-matched HC and the CHR patients (after statistically removing the effects of normal aging). Relative to HC, 1) SZ, ESZ, and CHR had smaller ERNs, and 2) SZ and ESZ had larger CRNs and smaller Pes. Within the SZ, longer illness duration was associated with larger CRNs but was unrelated to ERN or Pe. CHR and ESZ did not differ on ERN or CRN, although Pe was smaller in ESZ than CHR. These results indicate that while ERN, CRN, and Pe abnormalities are present early in the illness, only the ERN abnormality is evident prior to psychosis onset, and only the CRN abnormality appears to worsen progressively over the illness course. Brain regions subserving response monitoring may be compromised early in the illness and possibly during its clinical prodrome.     

Mother-Infant Psychotherapy Informed by Polyvagal Theory

This article illustrates the psychotherapeutic treatment of a 2-month-old male experiencing separation distress and problems in his regulatory system that were influencing the relationship with his mother. The baby was the product of a pregnancy complicated by maternal mental illness, homelessness, alcohol and drug exposure, lack of prenatal care, and a complicated delivery that required a 12-day hospital stay in the Neonatal Intensive Care Unit. The mother-infant psychotherapy was carried out over a two-year period and demonstrates the sensitive care needed when working with an overaroused and fearful baby and the critical ways that holding the mother in mind allows her in turn to hold her baby in mind. In this situation, the therapist provided an emotionally attuned interpersonal therapeutic relationship and created features of safety in the environment that helped develop new models of trust. We report here on an innovative program that provides health, mental health, onsite childcare, parenting education, and in-patient substance abuse services to mothers who are pregnant and/or parenting infants in the first three years of life. The specific purpose of the article is to discuss the mother-infant therapeutic treatment of a constitutionally challenged baby who was over aroused and fearful, and that we consider serves as an example for showing the favorable ways that holding the mother in mind free her to be emotionally available to the infant.     

Attachment styles and clinical correlates in people at ultra high risk for psychosis

Evidence suggests that attachment styles may influence subclinical psychosis phenotypes (schizotypy) and affective disorders and may play a part in the association between psychosis and childhood adversity. However, the role of attachment in the initial stages of psychosis remains poorly understood. Our main aim was to describe and compare attachment styles in 60 individuals at ultra high risk for psychosis (UHR) and a matched sample of 60 healthy volunteers (HV). The HV had lower anxious and avoidant attachment scores than the UHR individuals (p < .001). Sixty-nine percentage of the UHR group had more than one DSM-IV diagnosis, mainly affective and anxiety disorders. The UHR group experienced more trauma (p < .001) and more mood and anxiety symptoms (p < .001). Interestingly, in our UHR group, only schizotypy paranoia was correlated with insecure attachment. In the HV group, depression, anxiety, schizotypy paranoia, and social anxiety were correlated with insecure attachment. This difference and some discrepancies with previous studies involving UHR suggest that individuals at UHR may compose a heterogeneous group; some experience significant mood and/or anxiety symptoms that may not be explained by specific attachment styles. Nonetheless, measuring attachment in UHR individuals could help maximize therapeutic relationships to enhance recovery.

Emergent Power Hierarchies and Group Performance

In newly formed groups, informal hierarchies emerge automatically and readily. In this study, we argue that emergent group hierarchies enhance group performance (Hypothesis 1) and we assume that the more the power hierarchy within a group corresponds to the task‐competence differences of the individual group members, the better the group performs (Hypothesis 2). Twelve three‐person groups and 28 four‐person groups were investigated while solving the Winter Survival Task. Results show that emerging power hierarchies positively impact group performance but the alignment between task‐competence and power hierarchy did not affect group performance. Thus, emergent power hierarchies are beneficial for group performance and although they were on average created around individual group members' competence, this correspondence was not a prerequisite for better group performance.     

Entrevista a Dan I. Slobin

RESUMEN

El autor comienza explicando los factores que motivaron su interés por la psicolingüística evolutiva a principios de los sesenta. Tras exponer brevemente cuál es la significación del estudio del lenguje en la comprensión global del sujeto humano y justificar su atención a la adquisición de lenguas altamente inflexionales como el ruso o el turco, Slobin nos habla extensamente del Berkeley Crosslinguistic Acquisition Project (“Proyecto translingüístico sobre adquisición de Berkeley”), del cual fue uno de los máximos inspiradores. El autor aborda, además, cuestiones relativas a su teoría de la Gramática Básica Infantil, la síntesis de sus Principios Operativos para la adquisición del lenguaje o la posibilidad de aproximar las concepciones de Piaget y Chomsky. La última parte se reserva para las tendencias teóricas y de investigación que considera prometedoras en este campo, finalizando con algunas reflexiones en torno a la situación multilingüe de España y el estudio de la adquisición del lenguaje. Los comentarios de Miguel Pérez Pereira acerca de este importante investigador de la psicolingüística evolutiva introducen la entrevista.     

Dimensions of “uniquely” and “non‐uniquely” human emotions

Emotion scientists often distinguish those emotions that are encountered universally, even among animals ( “primary emotions”), from those experienced by human beings ( “secondary emotions”). No attempt, however, has ever been made to capture the lay conception about this distinction and to find the criteria on which the distinction is based. The first study presented in this paper was conducted in three countries involving four languages, so as to allow for cross‐cultural comparisons. Results showed a remarkable convergence. People from all samples not only differentiated between “uniquely human” and “non‐uniquely human” emotions on a continuum, but they did so on the same basis as the one used by emotion scientists to distinguish between “primary” and “secondary” emotions. Study 2 focused on the implicit use of such a distinction. When confronted with a human (animal) context, participants reacted faster to secondary (vs primary) emotions. The implications of the human uniqueness of some emotions within the social and interpersonal contexts are discussed.     

The Role of PTSD and Length of Shelter Stay in Battered Women's Severity of Reabuse after Leaving Shelter

Intimate partner violence (IPV) is associated with significant morbidity, including high rates of reabuse even after women have taken steps to achieve safety. This study evaluated the roles of posttraumatic stress disorder (PTSD) symptom severity and length of shelter stay in the severity of reabuse in 103 IPV victims over a six-month period after leaving a battered women's shelter. Results suggest that the length of shelter stay is inversely related to reabuse severity after leaving shelter. Additionally, more severe PTSD symptoms on shelter exit were associated with greater reabuse severity after leaving shelter. Furthermore, additional study findings support prior research suggesting that the emotional numbing symptoms of PTSD are a significant risk factor for reabuse among IPV victims after leaving shelter.
