Sistemas neurales de relevancia en el contexto de la psicobiología de la ansiedad: una revisión

Resumen

La ansiedad es un estado emocional central de características muy complejas que, al menos en términos de respuesta, se asemeja en gran medida al miedo. En las ültimas décadas, estudios neurobiológicos y psicobiológicos han identificado numerosas estructuras y circuitos cerebrales estrechamente relacionados con este tipo de respuestas, así como con el estado central característico. Destacan, por su especial relevancia, el sistema límbico (incluyendo el sistema septohipocampal, la amígdala y el hipotálamo posterior) y los sistemas monoaminérgicos ascendentes (principalmente de serotonina y norepinefrina), lugares donde, además, las sustancias ansiolíticas podrían ejercer su efecto terapéutico. El principal objetivo del presente trabajo es revisar la precisa implicación de estos sistemas neurales en la modulación de ese estado emocional definido como ansiedad.     

Pautas de adquisición y uso del pronombre personal en lengua española. Un estudio longitudinal

Resumen

El estudio sobre los pronombres personales, constituye también una manera de investigar la adquisición del lenguaje y su desarrollo, dado que son categorías lingüísticas. El niño no adquiere el dominio de estas categorías tan pronto como lo hace con otros aspectos del lenguaje, aunque los usa desde muy temprana edad. De esta manera suponemos que al comienzo el niño utiliza las formas pronominales únicamente como deícticos. Esto es, sólo puede comprenderse el significado de estos términos en las expresiones infantiles con referencia al tiempo y al contexto comunicativo presente y concreto. Por esta razón autores como Clark, (1974, 1978), Charney (1980), afirman que le pronombre personal, en su sentido lingüístico, no es adquirido por los niños hasta los ocho o nueve años de edad.

En el presente estudio intentamos poner de manifiesto cómo adquieren los niños españoles estos términos y cómo evolucionan en su desarrollo. Para ello, se realizó un análisis de la producción verbal de varios niños, en sus aspectos: sintáctico, semántico y pragmático. Dicha producción se recogió a través de observación natural. Los sujetos de este estudio de medios ambientales diferentes.     

Perceived Impact of Professional Counselor Identity: An Exploratory Study

Counselor educators (N= 378) provided their viewpoints regarding the impact of counselor identity on professional advancement and recognition. Respondents indicated that counselors, the American Counseling Association, and other counseling organizations are responsible for advocacy of the counseling profession. Collaboration among counselors for the development of a single coherent message is necessary for advocacy efforts aimed at congressional Medicare leaders, managed care organizations, state licensing boards, and allied professions.     

Social trauma: The pathogenic effects of untoward social conditions

Abstract

Psychoanalysis has traditionally overlooked the fact that unsuitable and damaging life conditions, originating in the social milieu, play a part in the pathogenesis of emotional suffering and mental disorders. Nonetheless, the self establishes an object relation with the social system, as well as with the non-human environment. This is expected to act as a container–contained relationship. Whenever the community and its institutions fail to act as a container for individuals and groups, this generates a trauma, which can be compared with the baby's experience of a failure in mothering. Such failures can be classified in several categories. The first is when the social system fails to contain, nurture, care for, and protect individuals, as in the case of the lack of assistance and compassion towards the victims of poverty, disease, natural catastrophe, social turmoil, economic crisis, violence, or war. The second category occurs when there is a blatant attack, on the part of the authorities or privileged social groups, on minorities, or even on the bulk of the population, as in the case of social repression, war—both internal and external—racism, genocide, or persecution. The third is when there is a perversion of the social system, which feigns to uphold current social values and laws while actually breaking them, as in the case of corruption, chicanery, and mendacity on the part of the authorities. One recent example of this is the impeachment process against the Chief of Government of Mexico City. The author approaches this problem by exploring the consequences of such experiences for the development and functioning of personality structure and personal relations, as well as their repercussions for individuals living together in the community and for the necessary relation between them and the authorities.     

‘What Would You Say if You Were Guilty?’ Suspects' Strategies During a Hypothetical Behavior Analysis Interview Concerning a Serious Crime

Previous research has shown that the Behavior Analysis Interview (BAI) indicators of guilt or innocence are merely commonsense notions. In this study, we examined whether this would lead suspects of a serious crime to try to manipulate their behavior during a BAI in order to look innocent. A serious crime was described to 74 undergraduates who were asked to imagine that they were guilty or innocent. They then completed a questionnaire about the strategies that they would use during a BAI. Both guilty and innocent suspects were more willing to show the innocence rather than guilt indicators of the BAI. Innocent suspects had a blind faith in the power of innocence to demonstrate that they were not guilty. The general (non‐BAI) strategies coincided with those of previous studies; this indicates that prior findings on strategies can be generalized to serious crimes and that strategies can be examined with uncomplicated procedures such as the one used in this study.

Neuropsychological impairments on the NEPSY-II among children with FASD

Background: We examined the pattern of neuropsychological impairments of children with FASD (compared to controls) on NEPSY-II measures of attention and executive functioning, language, memory, visuospatial processing, and social perception.

Methods: Participants included 32 children with FASD and 30 typically developing control children, ranging in age from 6 to 16 years. Children were tested on the following subtests of the NEPSY-II: Attention and Executive Functioning (animal sorting, auditory attention/response set, and inhibition), Language (comprehension of instructions and speeded naming), Memory (memory for names/delayed memory for names), Visual-Spatial Processing (arrows), and Social Perception (theory of mind). Groups were compared using MANOVA.

Results: Children with FASD were impaired relative to controls on the following subtests: animal sorting, response set, inhibition (naming and switching conditions), comprehension of instructions, speeded naming, and memory for names total and delayed, but group differences were not significant on auditory attention, inhibition (inhibition condition), arrows, and theory of mind. Among the FASD group, IQ scores were not correlated with performance on the NEPSY-II subtests, and there were no significant differences between those with and without comorbid ADHD.

Conclusions: The NEPSY-II is an effective and useful tool for measuring a variety of neuropsychological impairments among children with FASD. Children with FASD displayed a pattern of results with impairments (relative to controls) on measures of executive functioning (set shifting, concept formation, and inhibition), language, and memory, and relative strengths on measures of basic attention, visual spatial processing, and social perception.     

Contribution of parents' adult attachment and separation attitudes to parent‐adolescent conflict resolution

This study examined the contribution to parent‐adolescent conflict resolution of parental adult attachment styles and attitudes toward adolescent separation. Questionnaires were completed by 295 couples with early to late adolescent children. Structural equation models were used to test self and partner influences on conflict resolution for three attachment orientations: confidence (model A), anxiety (model B) and avoidance (model C). Model A showed self influences between parents' confidence orientation and negotiation and also via positive attitudes towards separation. Also, the fathers' use of negotiation was facilitated by the mothers' confidence orientation and vice versa, indicating partner influences as well. Model B showed self influences between parents' anxiety orientation and the use of dominance and withdrawal and also via negative attitudes towards separation. Model C showed self influences between parents' avoidance orientation and dominance and withdrawal, and a partner influence between fathers' avoidance and mothers' use of dominance. The results indicated that the parents' adult attachment system and the parenting system were related in the area of conflict resolution, and that self influences were stronger than partner influences.     

A longitudinal study of temperament continuity through IBQ,TBAQ and CBQ

The aim of this work was to study the continuity of temperament in a Spanish sample (n = 60), covering the developmental stages of infancy, toddlerhood and childhood. Temperamental dimensions showed, with few exceptions, as much homotypic as heterotypic continuity as was to be expected. At the level of latent superconstructs continuity, we found that Anger and Fear followed different developmental paths and showed continuity over all the periods evaluated. Positive Affect/Regulation superconstruct showed continuity from infancy to toddlerhood. From toddlerhood, Positive Affect/Regulation showed continuity with the superconstruct of Effortful Control but not with the superconstruct of Surgency/Extraversion. At an ipsative level, we found two groups of subjects, labeled ‘nonexpressive/controlled’ and ‘noncontrolled/expressive’. Generally, these results confirm the stability of temperament in the periods analyzed and underline the importance of toddlerhood as a transitional period in the maturity of self-regulatory capabilities shown in childhood.     

Experimental evidence for action imitation in killer whales (Orcinus orca)

Comparative experimental studies of imitative learning have focused mainly on primates and birds. However, cetaceans are promising candidates to display imitative learning as they have evolved in socioecological settings that have selected for large brains, complex sociality, and coordinated predatory tactics. Here we tested imitative learning in killer whales, Orcinus orca. We used a ‘do-as-other-does’ paradigm in which 3 subjects witnessed a conspecific demonstrator’s performance that included 15 familiar and 4 novel behaviours. The three subjects (1) learned the copy command signal ‘Do that’ very quickly, that is, 20 trials on average; (2) copied 100 % of the demonstrator’s familiar and novel actions; (3) achieved full matches in the first attempt for 8–13 familiar behaviours (out of 15) and for the 2 novel behaviours (out of 2) in one subject; and (4) took no longer than 8 trials to accurately copy any familiar behaviour, and no longer than 16 trials to copy any novel behaviour. This study provides experimental evidence for body imitation, including production imitation, in killer whales that is comparable to that observed in dolphins tested under similar conditions. These findings suggest that imitative learning may underpin some of the group-specific traditions reported in killer whales in the field.     

On the relationship between mobbing factors,and job content,social work environment,and health outcomes

Abstract

This article analyses the relationship between mobbing, job characteristics, social environment variables, and psychological ill-health. The Leymann Inventory of Psychological Terrorization (LIFT) was factor analysed and led to seven factors in two samples of mobbing victims (N = 50 and N = 99): Mobbing by organizational measures, social isolation, attacking the victim's private life, attacking the victim's attitudes, physical violence, verbal aggression, and rumours. Mobbing was correlated with bad job content, a bad social environment, and psychological ill-health. The findings suggest that the more social support supervisors gave, the less the victims reported being shouted at, being constantly criticized, and receiving verbal threats. In contrast, the more social support the victims received from their colleagues the less they reported being socially isolated or being ridiculed with regard to their private life. Moreover, having private life attacked showed the strongest correlation with psychological ill-health. The data suggest that organizational factors are potential causes of mobbing at work.
