Learning Stress

This paper uses the EEG analysis to investigate the relationship between pre-learning stress, frontal lope and long-term memory in the brain. The stress on learning stage is a challenge, especially in academic life. Stress also on learning stage affects the retrieval or recall from the memory. Nowadays; there are many recent works have discovered the relationship between stress, learning and memory performance based on different techniques. Some of these techniques are biological methods. Moreover, these methods have discovered the effect of stress based on hormones levels such as cortisol, or based on physiological effects such as blood pressure. However, these techniques have given conflicting discoveries because of the instability of hormones and an extensive number of related elements. The main aim of this research is to discover the relationship between Pre-learning stress, frontal lope, and long-term memory retrieval using EEG signals. The experimental results indicate that there is a relationship between theta rhythm in the frontal lobe and long-term memory retrieval during Pre-learning stress.

IntroductionThere is a hypothesis in cognitive psychology that long-term memory retrieval is improved by intermediate testing than by restudying the information. The effect of testing has been investigated with the use of a variety of stimuli. However, almost all testing effect studies to date have used purely verbal materials such as word pairs, facts and prose passages.ObjectiveHere byzantine music symbol–word pairs were used as to-be-learned materials to demonstrate the generalisability of the testing effect to symbol learning in participants with and without depressive symptoms.MethodFifty healthy (24 women, M age = 26.20, SD = 5.64) and forty volunteers with high depressive symptomatology (20 women, M age = 27.00, SD = 1.04) were examined. The participants did not have a music education. The examination material was completely new for them: 16 byzantine music notation stimuli, paired with a verbal label (the ancient Greek name of the symbol). Half of the participants underwent intermediate testing and the others restudied the information in a balanced design.ResultsResults indicated that there were no statistically significant differences in final memory test performance after a retention interval of 5 minutes for both groups of participants with low and high level depressive symptomatology (P > 0.005). After a retention interval of a week, tested pairs were retained better than repeatedly studied pairs for high and low depressive symptomatology groups (P < 0.005).ConclusionsThis research suggests that the effect of testing time on later memory retrieval can also be obtained in byzantine symbol learning.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The Relationship

Word learning is studied in a multitude of ways, and it is often not clear what the relationship is between different phenomena. In this article, we begin by outlining a very simple functional framework that despite its simplicity can serve as a useful organizing scheme for thinking about various types of studies of word learning. We then review a number of themes that in recent years have emerged as important topics in the study of word learning, and relate them to the functional framework, noting nevertheless that these topics have tended to be somewhat separate areas of study. In the third part of the article, we describe a recent computational model and discuss how it offers a framework that can integrate and relate these various topics in word learning to each other. We conclude that issues that have typically been studied as separate topics can perhaps more fruitfully be thought of as closely integrated, with the present framework offering several suggestions about the nature of such integration.

The Right

The hemispherical encoding retrieval asymmetry (HERA) model, established in 1991, suggests that the involvement of the right prefrontal cortex (PFC) in the encoding process is less than that of the left PFC. The HERA model was previously validated for episodic memory in subjects with brain traumas or injuries. In this study, a revised HERA model is used to investigate long-term memory retrieval from newly learned video-based content for healthy individuals using electroencephalography. The model was tested for long-term memory retrieval in two retrieval sessions: (1) recent long-term memory (recorded 30 min after learning) and (2) remote long-term memory (recorded two months after learning). The results show that long-term memory retrieval in healthy individuals for the frontal region (theta and delta band) satisfies the revised HERA asymmetry model.

Rapid Action

Quickly preventing the retrieval of (inappropriate) long-term memories might recruit a similar control mechanism as rapid action-stopping. A very specific characteristic of rapid action-stopping is “global motor suppression”: When a single response is rapidly stopped, there is a broad skeletomotor suppression. This is shown by the technique of TMS placed over a task-irrelevant part of the primary motor cortex (M1) to measure motor-evoked potentials. Here, we used this same TMS method to test if rapidly preventing long-term memory retrieval also shows this broad skeletomotor suppression effect. Twenty human participants underwent a Think/No-Think task. In the first phase, they learned word pairs. In the second phase, they received the left-hand word as a cue and had to either retrieve the associated right-hand word (“Think”) or stop retrieval (“No-Think”). At the end of each trial, they reported whether they had experienced an intrusion of the associated memory. Behaviorally, on No-Think trials, they reported fewer intrusions than Think trials, and the reporting of intrusions decreased with practice. Physiologically, we observed that the motor-evoked potential, measured from the hand (which was irrelevant to the task), was reduced on No-Think trials in the time frame of 300–500 msec, especially on trials where they did report an intrusion. This unexpected result contradicted our preregistered prediction that we would find such a decrease on No-Think trials where the intrusion was not reported. These data suggest that one form of executive control over (inappropriate) long-term memory retrieval is a rapid and broad stop, akin to action-stopping, that is triggered by the intrusion itself.

The Relationship

Two separate lines of research have examined the influence of song and infant-directed speech (IDS—a speech register that includes some melodic features) on language learning, suggesting that the use of musical attributes in speech input can enhance language learning. However, the benefits of these two types of stimuli have never been directly compared. In this investigation, we compared the effects of song and IDS for immediate word learning and long-term memory of the learned words. This study examines whether the highly musical stimuli (i.e., song) would facilitate language learning more than the less musical stimuli (i.e., IDS). English-speaking adults were administered a word learning task, with Mandarin Chinese words presented in adult-directed speech (ADS), IDS, or song. Participants’ word learning performance was assessed immediately after the word learning task (immediate word learning) and then 1 day later (long-term memory). Results showed that both song and IDS facilitated immediate word learning and long-term memory of the words; however, this facilitative effect did not differ between IDS and song, suggesting that the relationship between the degree of musicality and language learning performance is not linear. In addition, song and IDS were found to facilitate the word association process (mapping a label to its referent) rather than the word recognition process. Finally, participants’ confidence in their answers might not differ among ADS, IDS, and sung words.

A neurociência é uma ciência natural que estuda a função e a estrutura, que compõem o cérebro. A educação, embora tenha outra natureza, tem tido muitos benefícios com as contribuições que a neurociência tem para oferecer. Como o cérebro aprende e por que aprende traz para o ensino o objetivo e a função de criar condições (entre estratégias, recursos e adequação do meio), para que ocorra a aprendizagem. E, para que essa ocorra, é necessário que as funções mentais superiores, como a memória, estejam envolvidas. O objetivo deste estudo consiste em fazer uma revisão de literatura para conhecer a função da memória de longo prazo na aprendizagem, analisar os mecanismos neurobiológicos, que ocorrem durante esse processo e algumas estratégias de aprendizagem, que se utilizam da memória como recurso. Para isso, foi realizado no período de agosto a outubro de 2016, um levantamento bibliográfico nas bases de dados Scielo, Capes, Bireme e Google Acadêmico, buscando artigos científicos, que poderiam trazer alguma contribuição na construção dessa pesquisa. Foram selecionados, preferencialmente, os que continham enfoque na relação entre aprendizagem e memória, tanto na perspectiva da neurociência, quanto da psicologia cognitiva, trazendo argumentos que pudessem  comprovar o entendimento das estratégias de aprendizagem, a partir da memória de longo prazo. Também foram selecionados livros que apresentavam apoio às temáticas discorridas para esse trabalho, possibilitando essa relação. Os resultados apontam que estratégias de aprendizagens, que utilizam a memória, produzem efeitos positivos para a retenção de longo prazo.Palavras-chave: Aprendizagem. Neurociências. Estratégias de Aprendizagem.AbstractNeuroscience is a natural science that studies the function and structure that forms the brain. Although education has another nature, it has had many benefits from the contributions that neuroscience has to offer. How the brain learns and why it learns brings to teaching the intent and function to create conditions (among strategies, resources and suitability to the environment) so that learning can happen. And, for it to occur, it is  necessary that higher mental functions, such as memory, beinvolved. The purpose of this study is to do a literature review to get to know the function of long-term memory on the learning process, to analyze the neurobiological mechanisms that happen during that process, and some learning strategies that use memory as a resource. Therefore a bibliographical survey was conducted at the databases Scielo, Capes, Bireme and Academic Google, from August to October 2016, searching for scientific articles that could contribute somehow on the construction of this research. The articles that used the neuroscience perspective or the cognitive psychology to focus on the relationship  between learning and memory were chosen, preferentially those whose arguments could prove the  learning strategies understanding about he long-term memory. Books supporting the themes discussed for this work were also selected, creating, therefore, a relationship. The results show that learning strategies that use memory have positive effects for long-term retention.Keywords: Learning. Neuroscience. Learning Strategies.
