Animación, documental y memoria. la representación animada de la dictadura chilena

2018

La animación aparece cada vez más en producciones sobre sucesos relacionados con la memoria. Nuestro objetivo es analizar las obras que incorporan escenas animadas para representar la dictadura chilena y profundizar en la convergencia entre animación, documental y memoria. Desde una perspectiva cualitativa, combinamos el análisis de las animaciones con entrevistas a sus directores. Los resultados muestran que la animación es un formato versátil, que permite a los autores superar la ausencia de imágenes de archivo, suavizar el grado de representación de los sucesos traumáticos, abaratar costes, conectar la memoria con las nuevas generaciones y favorecer la empatía del espectador.

Hippocampal theta phase-contingent memory retrieval in delay and trace eyeblink conditioning

2017

Hippocampal theta oscillations (3–12 Hz) play a prominent role in learning. It has been suggested that encoding and retrieval of memories are supported by different phases of the theta cycle. Our previous study on trace eyeblink conditioning in rabbits suggests that the timing of the conditioned stimulus (CS) in relation to theta phase affects encoding but not retrieval of the memory trace. Here, we directly tested the effects of hippocampal theta phase on memory retrieval in two experiments conducted on adult female New Zealand White rabbits. In Experiment 1, animals were trained in trace eyeblink conditioning followed by extinction, and memory retrieval was tested by presenting the CS at …

Learning to learn: Theta oscillations predict new learning, which enhances related learning and neurogenesis

2012

Animals in the natural world continuously encounter learning experiences of varying degrees of novelty. New neurons in the hippocampus are especially responsive to learning associations between novel events and more cells survive if a novel and challenging task is learned. One might wonder whether new neurons would be rescued from death upon each new learning experience or whether there is an internal control system that limits the number of cells that are retained as a function of learning. In this experiment, it was hypothesized that learning a task that was similar in content to one already learned previously would not increase cell survival. We further hypothesized that in situations in…

Hippocampal theta activity is selectively associated with contingency detection but not discrimination in rabbit discrimination-reversal eyeblink con…

2010

The relative power of the hippocampal theta-band (∼6 Hz) activity (theta ratio) is thought to reflect a distinct neural state and has been shown to affect learning rate in classical eyeblink conditioning in rabbits. We sought to determine if the theta ratio is mostly related to the detection of the contingency between the stimuli used in conditioning or also to the learning of more complex inhibitory associations when a highly demanding delay discrimination-reversal eyeblink conditioning paradigm is used. A high hippocampal theta ratio was not only associated with a fast increase in conditioned responding in general but also correlated with slow emergence of discriminative responding due to…

The relationship between navigation abilities and mental disorders: Poster

2021

This study examined the relationship between aspects of navigational ability and behavioral traits associated with various mental disorders. We propose that navigational ability may utilize the same brain circuitry that has dysfunction in certain mental disorders and may be a beneficial early marker for these disorders. This study was inspired by the Research Domain Criteria (RDoC), a framework outlined by NIMH to study the basic dimensions of functioning that span the range of behavior from normal to abnormal. For example, we hypothesized that spatial perspective taking, which is important for navigation, could be associated with social perspective taking in disorders such as autism spectr…

Prerequisites for the successful group mentoring of first-year university students: a case study

2018

In this article we present a case study on a group mentoring practice proven successful in earlier studies in terms of student self-regulation and collaboration. The purpose of our study was to unc...

Basic Empathy Scale: A Systematic Review and Reliability Generalization Meta-Analysis

2022

The Basic Empathy Scale (BES) has been internationally used to measure empathy. A systematic review including 74 articles that implement the instrument since its development in 2006 was carried out. Moreover, an evidence validity analysis and a reliability generalization meta-analysis were performed to examine if the scale presented the appropriate values to justify its application. Results from the systematic review showed that the use of the BES is increasing, although the research areas in which it is being implemented are currently being broadened. The validity analyses indicated that both the type of factor analysis and reliability are reported in validation studies much more than the …

Pirmā tipa cukura diabēta pacientu klīniskais novērojums endokrinologa praksē: metabolās kompensācijas novērtējums, akūto komplikāciju blakusslimību …

2017

Pētījuma darba galvenais mērķis ir analizēt dažāda smaguma hipoglikēmiju biežumu pirmā tipa cukura diabēta pacientiem un salīdzināt to ar diabēta metabolo kompensāciju. Materiāli un metodes: pētījumā tika analizētas „Latvijas Universitātes Medicīniskās pēcdiploma izglītības institūta” Dr.med. Kristīnes Ducenas pacientu ambulatorās kartes. Tika analizēti pacientu dati ar apstiprinātu diagnozi – pirmā tipa cukura diabēts. Atsevišķi tika apstrādāti dati par pacienta dzimumu, vecumu, cukura diabēta ilgumu (gados), HbA1C līmeni un citām autoimūnām blakussaslimšanām. Atkarībā no HbA1c līmeņa, pētījuma dalībnieki tika sadalīti sekojošās grupās: ●Pirmā grpa- laba diabēta kompensācija (HbA1c 7,5%). …

Exploring students’ metacognition in relation to an integral-area evaluation task

2021

Several studies have been conducted to explore students’ understanding of the integral-area relationships, however, only a few focused on students’ metacognition in relation to this topic. In this study, students’ metacognitive knowledge, skills, and experiences in relation to an integral-area evaluation task are explored using semi-structured interviews and think-aloud protocol. The results show that several students developed monitoring strategies in relation to integral-area relationships; however, they do not use these strategies when solving integral-area tasks. The findings suggest that teachers and lecturers could use monitoring strategies more often when solving mathematical questio…
