Autobiographical Memory for Stressful Events, Traumatic Memory and Posttraumatic Stress Disorder: A Systematic Review

Stressors and traumatic events may contribute to the development of many psychopathologies, PTSD among them. People with this disorder can present significant cognitive impairments and losses in memory, particularly autobiographical memory (AM).This paper aims to present a systematic review of literature considering changes on autobiographical memory in people exposed to potentially traumatic stressors. Therefore, we performed a computerized search in databases PsycINFO, PubMed, Web of Science and Pilots in March 2012.A total of 29 articles were selected and grouped into three categories: studies comparing Trauma X PTSD, studies comparing PTSD X Trauma X Control and comparison studies according to post-traumatic symptoms. Results demonstrate that people with PTSD presents alterations in a larger number of AM components compared to the cases in which PTSD did not developed. In the same way, subjects never exposed to trauma did not demonstrate significant alterations on  AM when compared to the other groups. The results of this study allowed concluding that changes of some components of the AM are primarily associated with PTSD, but it was not possible to clarify whether such changes are related to the timely development of the disorder, or if they are also observed in traumatic memories even in the absence of disorder.

Funciones cognitivas de individuos positivos para VIH/SIDA asistentes a un programa de atención integral

Objetivos. Caracterizar el perfil neuropsicológico de una muestra de 22 pacientes diagnosticados con VIH/SIDA, de un hospital de 4to nivel de Bogotá. Materiales y métodos. Estudio descriptivo de tipo exploratorio. Se hizo una descripción de las características neuropsicológicas de las personas con VIH/SIDA. Los resultados de la evaluación neuropsicológica de los sujetos se analizaron con el programa SPSS. Las variables registradas fueron edad, genero, escolaridad, tiempo de diagnóstico y funciones cognitivas superiores. Se incluyeron en el estudio los sujetos con diagnóstico de VIH/SIDA y con reportes de quejas subjetivas de memoria. No se excluyeron aquellos sujetos con antecedentes o presencia de alteraciones psiquiátricas. Resultados. Se creó una base de datos de 22 sujetos, de los cuales predominaron participantes del sexo masculino (77.3%); edad promedio 53,5 años. Se encontró que las funciones con mayor compromiso, sin importar tiempo de diagnóstico, fueron la atención sostenida, la memoria declarativa y la función ejecutiva (control inhibitorio). Las funciones más preservadas fueron las visoespaciales. Conclusiones. Es fundamental que los sujetos con diagnóstico de VIH/SIDA, sean valorados desde un inicio por neuropsicología para incluirlos en un protocolo de prevención y rehabilitación cognitiva específico para dicha población. Se recomienda que el protocolo sea diseñado por un equipo multidisciplinar de diferentes profesionales de la salud.

Analysis of psychological aspects of Lovemarks formation

El presente trabajo es una revisión de literatura que busca contribuir al entendimiento de los procesos psicológicos subyacentes en la Teoría de Roberts sobre Lovemarks que, dentro del campo del marketing, ha buscado reemplazar la idea que se tiene sobre las marcas. La primera parte proporciona una introducción de lo que ha sido la evolución de las marcas desde una perspectiva psicológica y de mercadeo. En la segunda parte se explica la teoría de Lovemarks haciendo énfasis en sus componentes: el eje amor/respeto, las características de misterio, sensualidad e intimidad. Adicionalmente, se soporta esta teoría a través de literatura complementaria y casos de aplicación exitosos. La tercera parte, corresponde a la identificación y análisis de los procesos y aspectos psicológicos que explican la formación de un Lovemark: percepción, memoria, motivación individual y social y emoción. La cuarta y última parte contiene las conclusiones e implicaciones en la formación de la relación entre el consumidor y una marca.

Contribution from neuropsychology to the study of semantic memory

Semantic memory has been studied from various fields. The first models emerged from cognitive psychology from the hand of the division proposed by Tulving between semantic and episodic memory. Over the past thirty years there have been parallel developments in the fields of psycholinguistics, cognitive psychology and cognitive neuropsychology. The present work is to review the contributions that have emerged within the neuropsychology to the study of semantic memory and to present an updated overview of the points of consensus. First, it is defined the term "semantics" conceptually within the field of neuropsychology. Then, there is a dichotomy that passes through both psychological and neuropsychological models on semantic memory: the existence of modals versus amodal representations. Third, there are  developed the main theoretical models in neuropsychology that emerged in an attempt to explain categoryspecific semantic deficits. Finally, more robust contributions and points that still generate some discussion are reviewed.

Social skills of children with different disabilities: Assessment and implications for interventions

This study characterizes the differences and similarities in the repertoire of social skills of children from 12 different categories of special educational needs: autism, hearing impairment, mild intellectual disabilities, moderate intellectual disabilities, visual impairment, phonological disorder, learning disabilities, giftedness and talent, externalizing behavior problems, internalizing behavior problems, internalizing and externalizing behavior problems and attention deficit hyperactivity disorder. Teachers of 120 students in regular and special schools, aged between 6 and 14 years old, from four Brazilian states, responded to the Social Skills Rating System. Children with ADHD, autism, internalizing and externalizing behavior problems and externalizing behavior problems presented comparatively lower frequency of social skills. The intervention needs of each evaluated category are discussed.

The Ergonomic Analysis and Back Injuries in Flexible Production System

Back injuries identification and diagnoses in the transition of the Taylor model to the flexiblemodel of production organization, demands a parallel intervention of prevention actors at work. This study uses simultaneously three intervention models (structured action analysis, muscle skeletal symptoms questionnaires and muscle skeletal assessment) for work activities in a packaging plant. In this study seventy and two (72) operative workers participated (28 workers with muscle skeletal evaluation). In an intervention period of 10 months, the physical, cognitive, organizational components and productive process dynamics were evaluated from the muscle skeletal demands issues. The differences established between objective exposure at risk, back injury risk perception, appreciation and a vertebral spine evaluation, in prior and post intervention, determines the structure for a muscle skeletal risk management system. This study explains that back injury symptoms can be more efficiently reduced among operative workers combining measures registered and the adjustment between dynamics, the changes at work and efficient gestures development. Relevance: the results of this study can be used to pre ent back injuries in workers of flexible production processes.

El análisis multifactorial del trabajo estático y repetitivo. Estudio del trabajo en actividades de servicio

El trabajo de oficina y, específicamente, el trabajo con computador se realizan en períodos prolongados de trabajo estático, lo que se asocia con el desarrollo de desordenes músculo esqueléticos. En consecuencia, los autores desarrollaron un estudio transversal, a partir de la evaluación de trabajadores de oficina (n=377) de una empresa dedicada a actividades de servicio4(gestión de información y atención al cliente), con el objetivo de explorar la relación entre la estructura del trabajo, la naturaleza de las tareas y la presencia de problemas osteomusculares e identificar los principios de una estrategia que estimule la transición postural. La información se recolectó a través de un formulario que indagó sobre variables relativas al tipo de cargo que desempeña el trabajador, el tiempo dedicado a actividades informáticas, incapacidades, antecedentes médicos y sintomatología actual. Como principales antecedentes médicos en la población evaluada se encontró: hipertensión arterial (HTA), 8%; dislipidemia, 23%; diabetes, 3%, e hipoglicemia, 4%. En los trabajadores evaluados se encontró que el 80% refiere dolor, específicamente relativo al miembro superior: manos, 26%; codos, 3%, y hombros, 4%. En columna cervical, 32%; lumbar, 16%, y dorsal, 6%. Finalmente, se evidenció que el 80% del tiempo laboral del personal estudiado es empleado en actividades de trabajo estáticas, dedicadas en su mayoría a la digitación de datos. Los resultados de este estudio se aplican al desarrollo de principios para el diseño de tareas y de una estrategia que busca potenciar las transiciones de postura en el trabajo. 

How do inequality affect tax morale in Latin America and Caribbean?

Latin America is well known as an inequitable region. As it is recognized, inequality and corruption perception weaken the way that political institutions works and the democratic system. Focusing on Latin American and Caribbean countries, this paper analyzes what are the elements shaping tax morale. In particular, how the context influences ethical grounds decisions such as the predisposition to pay taxes is analyzed, using the survey carried out in 2005 by Latinobarometro. The objective is to analyze how country performance determines tax morale. To do so, four probitmodels are estimated using Gini index, Transparency International Corruption Perception Index and Gross Domestic Product per capita (GDPpc) as explanatory variables. As expected we found that some socio-demographic variables play a relevant role. Interestingly, we also found that, in this attitude, LAC countries do not register a gender bias. However, those are not our main contributions to the literature on the field. The most important results are linked to: 1) the levelmatters, GDPpc increases the probability of people having tax morale, 2) moreover, income distributionalso influence on tax morale but in opposite direction and 3) corruption perception also reduces tax morale. Those results show that the quality of institutions matters and therefore, the way that democracy works play a relevant role.
