Santa Bárbara, el barrio que no soportó las tempestades: el olvido y la demolición del patrimonio arquitectónico en la construcción del relato histórico de Bogotá entre 1980 y 1983

Esta investigación analiza la construcción del límite sur de la zona patrimonial de Bogotá de los años 80, a partir de dos procesos simultáneos: la demolición de un sector del barrio Santa Bárbara y la patrimonialización de La Candelaria. A pesar de que estos dos sectores de la ciudad hicieron parte de la ciudad antigua y compartieron un origen común, solo La Candelaria logró hacer parte de la zona considerada de valor histórico. Por lo tanto, este proyecto de grado se interesa, principalmente, por conocer por qué el barrio Santa Bárbara fue excluido del relato histórico de la ciudad, a partir del estudio de la discusión sobre su valor histórico que dio paso al uso público del pasado y a una “lucha por la memoria”, en palabras de Elizabeth Jelin.

Working memory in school-aged children: Exhibition intervals and distracters effects in Memonum computerized test

This study assessed visual working memory through Memonum computerized test in schoolchildren. The effects of three exposure times (1, 4 and 8 seconds) have been evaluated, and the presentation of a distractor on the mnemonic performance in the test Memonum in 72 children from a college in the metropolitan area of Bucaramanga, Colombia, aged between 8 and 11 in grades third, fourth and fifth grade. It has been found significant difference regarding the exposure time in the variables number of hits and successes accumulated, showing a better mnemonic performance in participants who took the test during 8 seconds compared to children who took the test during 1 second; in addition, the presence of a distractor showed a significant difference regarding the strengths and successes accumulated. Such distractor is considered a stimulus generator interference that disrupts the storage capacity of working memory in children. Additionally, a significant difference was found with respect to the use of mental rehearsal strategy, indicating that participants who took the test in 4 and 8 seconds, respectively, assigned higher scores than children who took the test in 1 second. A long exposure time to stimuli during Memonum test increases the holding capacity. Also, the use of a distractor affects the storage capacity and this, at the same time, increases the school progression due to the use of mnemonic strategies that children use to ensure the memory of the numerical series

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.

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.

Utopías interculturales Intelectuales públicos, experimentos con la cultura y pluralismo étnico en Colombia

Este libro estudia la región suroccidental del Cauca - Colombia, una zona que es cultural y lingüísticamente heterogénea, conocida por su historia de movilización indígena y el carácter pluralista de su política étnica. La autora entreteje las historias de vida de activistas individuales con un análisis de la trayectoria del Consejo Regional Indígena de Cauca y otras organizaciones de este tipo. Presenta nuevas interpretaciones del movimiento y de las relaciones interculturales que lo definen, desde las diversas perspectivas de activistas regionales indígenas, intelectuales urbanos no indígenas que colaboran con estas organizaciones, antropólogos, maestros, chamanes y políticos.
