Rhesus monkeys know when they remember

Humans are consciously aware of some memories and can make verbal reports about these memories. Other memories cannot be brought to consciousness, even though they influence behavior. This conspicuous difference in access to memories is central in taxonomies of human memory systems but has been difficult to document in animal studies, suggesting that some forms of memory may be unique to humans. Here I show that rhesus macaque monkeys can report the presence or absence of memory. Although it is probably impossible to document subjective, conscious properties of memory in nonverbal animals, this result objectively demonstrates an important functional parallel with human conscious memory. Animals able to discern the presence and absence of memory should improve accuracy if allowed to decline memory tests when they have forgotten, and should decline tests most frequently when memory is attenuated experimentally. One of two monkeys examined unequivocally met these criteria under all test conditions, whereas the second monkey met them in all but one case. Probe tests were used to rule out “cueing” by a wide variety of environmental and behavioral stimuli, leaving detection of the absence of memory per se as the most likely mechanism underlying the monkeys' abilities to selectively decline memory tests when they had forgotten.

Partial Product Reduction based on Look-Up Tables

In this paper a new technique for partial product reduction based on the use of look-up tables for efficient processing is presented. We describe how to construct counter devices with pre-calculated data and their subsequent integration into the whole operation. The development of reduction trees organizations for this kind of devices uses the inherent integration benefits of computer memories and offers an alternative implementation to classic operation methods. Therefore, in our experiments we compare our implementation model with CMOS technology model in homogeneous terms.

Reflexiones sobre la investigación acción en el abordaje de las memorias e identidades indígenas kollas en la ciudad de La Plata

Este trabajo tiene como finalidad presentar los principales lineamientos de lo que constituye mi proyecto tesis de investigación de posgrado explicitando los objetivos generales y particulares que se buscan alcanzar. Asimismo, se presentan cuestiones referidas a los desafíos que plantea el trabajo con entrevistas y observaciones participantes, especialmente las que atañen prácticas de grupos tradicionalmente silenciados y relegados al olvido como son las comunidades indígenas de Argentina. La posibilidad de entablar vínculos estrechos con miembros de estas comunidades que permitan dar cuenta de las experiencias personales y colectivas, las memorias sociales compartidas, las herencias ancestrales y culturales, constituye el resultado de un trabajo sostenido en el largo plazo. En este caso, el desarrollo de ésta investigación se plantea como un proceso conjunto y participativo, fruto de una experiencia de extensión universitaria que permitió el acercamiento y vinculación con la comunidad kolla, Asociación Civil Warmikunamanta Antipak Sonqokuna. En consecuencia, se buscará abrir a la reflexión sobre la producción de saberes en ciencias sociales, especialmente en los estudios sobre sociedades indígenas del siglo XXI

Adjusting to change through song: Themes in songs written by clients with traumatic brain injury

The study aimed to identify themes in songs written by clients with traumatic brain injury (TBI). Lyrics (1834) from 82 songs written by 11 female and 21 male clients aged between 5 and 60 years were categorised into 8 main themes and 24 subcategories. Incidence of subcategories and themes were calculated. Self-reflections and messages were the most frequent themes portrayed within songs. Memories and reflections about significant others were also frequently communicated. It was noticeable that clients felt safer to communicate thoughts and feelings about the past and present but were less inclined to confront the future.

Contribuição à história dos batistas Sul-Mato-grossenses a partir da memória coletiva Um Recorte Biográfico da missionária Ann Mae Louise Wollerman

Esta pesquisa parte do interesse de análise da contribuição da missionária Ana Wollerman para o crescimento da denominação batista no sul de Mato Grosso e Mato Grosso do Sul, no período compreendido entre os anos de 1948 a 1978. A memória religiosa e autobiográfica da missionária apresenta experiências com o sagrado que marcam divisores de fases e temporalidades no seu recorte biográfico e que influenciam decisivamente na postura ministerial adotada. As entrevistas com algumas pessoas que participaram das comunidades afetivas existentes e os registros nas atas lidas constatam em grande parte os dados coletados pela memória. Ana Wollerman, filha de descendentes de alemães nos E.U.A., graduou-se em Artes e pósgraduou- se em Educação Religiosa. Veio para o Brasil inicialmente como missionária sem depender do sustento financeiro de uma Junta Missionária, fundou diversas escolas de ensino primário, trabalhou na implantação de diversas igrejas e dedicou grande parte de seus esforços no ensino ministerial. Foi responsável pela ajuda financeira no sustento de mais de uma dezena de jovens nos Seminários de Curitiba-PR, no IBER-RJ e no Seminário do Sul-RJ. Contribuiu também para que fossem destinadas grandes ofertas para a construção do Seminário Teológico Batista em Dourados. O trabalho procura seguir uma metodologia ainda em construção no que se refere à memória religiosa e utiliza o referencial teórico de Maurice Halbwachs para apresentar as memórias individuais e construção da memória coletiva, bem como tem apoio no próprio Halbwachs ao trabalhar a leitura da formação das comunidades afetivas. Aliado a estas questões se presta como um primeiro tratado sobre a historiografia da denominação batista em Mato Grosso e Mato Grosso do Sul, reunindo aspectos da sua gênese e do seu desenvolvimento. O resgate e a valorização da memória do sujeito-objeto em questão, ainda em vida constitui também no reconhecimento que a academia pode prestar às pessoas e às comunidades que se dedicam à construção de um mundo melhor.(AU)

PUBLICIDADE E O CONSUMO INFANTIL: Uma abordagem crítica

A sociedade de consumo contemporânea apresenta inúmeras produções textuais envolvendo a temática publicidade e consumo infantil . Sua complexidade divide opiniões, favoráveis e desfavoráveis, a respeito da legitimidade, da ética e da moral da publicidade dirigida à criança. Esta tese apresenta o cenário atual da publicidade infantil brasileira e como as crianças pensam, praticam e influenciam o consumo não planejado. A constituição do cenário infantil brasileiro foi desenvolvida em três etapas: a primeira, foi construída um painel da publicidade infantil , com a análise de 19 artigos científicos de todas as regiões do Brasil, que possibilitou a compreensão e a visão dos principais pesquisadores brasileiros sobre a temática, com isso, foram ouvidas, 433 crianças de 6 a 12 anos da classe socioeconômica A/B da cidade de Santos Litoral Sul do Estado de São Paulo, projetando a realidade que a publicidade exerce sobre o consumo infantil e a compra não planejada, na opinião das crianças. Na segunda etapa, foram ouvidos especialistas de diversas áreas e segmentos da sociedade, que se relacionam diretamente com o público infantil, que contribuíram com opiniões, críticas e visões dessa tendência comportamental das crianças modernas. Na terceira e última etapa, foram ouvidos, por intermédio de entrevista, os pais, objetivando compreender como e de que forma eles presenciam e contribuem para a compra não planejada dos seus filhos. O resultado revela as principais causas e efeitos que a publicidade direcionada para as crianças proporciona no comportamento de consumo e social da criança e da família (na opinião dos especialistas), os corresponsáveis desses efeitos e o que se espera para o cenário ético do consumo infantil brasileiro.

A working memory bias for alcohol-related stimuli depends on drinking score

We tested 44 participants with respect to their working memory (WM) performance on alcohol-related versus neutral visual stimuli. Previously an alcohol attentional bias (AAB) had been reported using these stimuli, where the attention of frequent drinkers was automatically drawn toward alcohol-related items (e.g., beer bottle). The present study set out to provide evidence for an alcohol memory bias (AMB) that would persist over longer time-scales than the AAB. The WM task we used required memorizing 4 stimuli in their correct locations and a visual interference task was administered during a 4-sec delay interval. A subsequent probe required participants to indicate whether a stimulus was shown in the correct or incorrect location. For each participant we calculated a drinking score based on 3 items derived from the Alcohol Use Questionnaire, and we observed that higher scorers better remembered alcohol-related images compared with lower scorers, particularly when these were presented in their correct locations upon recall. This provides first evidence for an AMB. It is important to highlight that this effect persisted over a 4-sec delay period including a visual interference task that erased iconic memories and diverted attention away from the encoded items, thus the AMB cannot be reduced to the previously reported AAB. Our finding calls for further investigation of alcohol-related cognitive biases in WM, and we propose a preliminary model that may guide future research. © 2012 American Psychological Association.

Proactive environmental systems:the next generation of environmental monitoring

In this article we envision factors and trends that shape the next generation of environmental monitoring systems. One key factor in this respect is the combined effect of end-user needs and the general development of IT services and their availability. Currently, an environmental (monitoring) system is assumed to be reactive. It delivers measurement data and computational results only if the user explicitly asks for it either by query or subscription. There is a temptation to automate this by simply pushing data to end-users. This, however, leads easily to an "advertisement strategy", where data is pushed to end-users regardless of users' needs. Under this strategy, the mere amount of received data obfuscates the individual messages; any "automatic" service, regardless of its fitness, overruns a system that requires the user's initiative. The foreseeable problem is that, unless there is no overall management, each new environmental service is going to compete for end-users' attention and, thus, inadvertently hinder the use of existing services. As the main contribution we investigate the nature of proactive environmental systems, and how they should be designed to avoid the aforementioned problem. We also discuss how semantics, participatory sensing, uncertainty management, and situational awareness link to proactive environmental systems. We illustrate our proposals with some real-life examples.

Disowned recollections:denying true experiences undermines belief in occurrence but not judgments of remembering

Recent research findings have illustrated that false memories induced in the laboratory can be dissociated from the beliefs that the events had in fact occurred. In this study we assessed whether this dissociability is a quality peculiar to false memory, or whether it represents a general characteristic of autobiographical memory. To this end we examined whether people can be induced to stop believing in memories for true experiences. Participants observed and performed simple actions, and were later falsely informed that they had not performed some of them-that false memories for these actions had been implanted through the use of fabricated evidence. Before and after receiving this misinformation, participants rated their belief in and memory of performing those actions, other actions that they had also performed, and actions that they had not performed. Whereas the misinformation substantially undermined participants' beliefs in the specific performed actions about which they had been misinformed, it had little effect on their endorsement of remembering those actions. The misinformation thus boosted the proportion of occasions in which participants rated their memories as stronger than their beliefs, and it weakened the correlation between belief and memory ratings. Thus, this study provides the first experimental demonstration of non-believed memories of true experiences. We discuss our findings with reference to the small literature concerning the use of socially-communicated misinformation to undermine event memories, and with reference to the structure of autobiographical memory. © 2013 Elsevier B.V.

A phenomenology of crack abuse

The aim of this dissertation is to identify, describe, and explain the common experiences defining the crack abuser's life-world. Its method is phenomenological. Using basic cybernetic premises, a neurophysiologically oriented phenomenological framework concerning the constitution of thoughts, memories, and perceptions is first written. The framework is designed to hypothetically represent the neuropathology of crack abuse within a perspective that prescinds and describes the constitution, flow, and interdependence of experience. After the framework is written, the dissertation outlines the neuro-psychopharmacology of crack abuse and delimits crack abusers as a specific group within the more general population of cocaine users. It then represents the neuropathology of crack abuse within its phenomenological framework and uses the first-person accounts of forty-two crack dependents to actualize a phenomenological sketch of the crack abuser's life-world. The ethnographies afford the possibility of writing a “thick” description of the crack abuser's daily life—one that communicates the substance, order, and subjective and cultural dimensions of the dependent's defining experiences. ^ The dissertation's goals are successfully realized. The framework written and the ethnographies recorded and transcribed, the dissertation is able to identify, describe, and to a certain extent explain some of the common experiences defining the crack abusers life-world. The dissertation concludes that the crack abuser's life-world is organized around three primary and four secondary experiences. His primary experiences include: (1) an almost complete, yet fleeting, satisfaction of the ego's innate insufficiency and sublime, erotic-like stimulation of its core, (2) a fundamental inclination and expansion of the uniquely oriented euphoria-dysphoria dynamic that vivifies and orients the flow of consciousness, and (3) a change in the ego's innate structure. His secondary experiences include: (a) a characteristic aiming of projects, actions, and conduct toward the procurement and consumption of crack, (b) a denigration in the hold of legitimations and institutionalizations on the thematic field, (c) a strict alignment and a contraction in the scope of logical types pointing to the salient experiences within the stock of knowledge, and (d) for some crack abusers, ontological insecurity, despair, and exhaustion. ^

Factors positively influencing academically successful, highly motivated African -American high school students

The purpose of this study is two-fold: (1) to investigate the common factors positively influencing academically successful, highly motivated African-American high school students in their educational pursuits; and (2) to determine ways in which educators can facilitate an increased positive impact on minority students' achievement motivation and transition to higher education. ^ Three sources of data inform the qualitative study. Short autobiographical essays address the topic of antecedent factors influencing the students' selection of an academic program of study. Individual interviews using a semi-structured format elicit discussion of prior experiences and influences related to the research sub-questions. Focus group interviews elicit discussion of emergent patterns perceived by the researcher from the autobiographical essays and individual interviews. ^ Results indicate a generic model for success for high achieving African-American students. Students prioritize education as a means to success in life. They receive strong support for educational aspirations from at least one adult within the home. The students are focused on a professional career in the future. The students realize and desire the financial benefits of academic success. The students desire academic challenge. Students have feelings of control over their academic choices; however, they frequently seek the counsel of family members. Prior experience in honors, gifted, or magnet programs did not meet needs. ^ Recommendations for improved educational experiences include: Increase teacher and counselor responsiveness to students. Provide classroom activities which afford more interaction among the students and teacher and relate curriculum to topics of interest. Increase involvement of parents and Black community members in establishing goals and visions of opportunity. Recognize and revere diversity among students within the classroom environment. Set a climate that assumes more individual student responsibility and sets higher academic expectations. ^ The factors influencing academically successful, highly motivated African-American high school students echo the patterns of experiences of many groups. Pride in achievement, emotional support for efforts, expectations of success, independence in thought, and consternation with mediocrity and malaise drive the students to excel academically just like all others who succeed. ^
