Learning is crucial in everyday life. However, how much information we retain depends on the type and schedule of training. It has been widely acknowledged that spaced learning holds a distinct advantage over massed learning for cognitively healthy adults and should be considered an educational standard, particularly when consolidating long-term memory. Given that many experiments have been required to be conducted online as a result of social distancing regulations during the Covid-19 pandemic, we examined whether the spacing advantage could be replicated in an online setup. Two experiments were conducted to examine the effects of spacing across recent (24 hours) and remote (one-month) retention intervals using the Face-Name Pairs task either in-person (Experiment 1) or online (Experiment 2). The results of Experiment 1 suggest that the beneficial memory effects of spaced training are particularly observed with remote memory. The results of Experiment 2 suggest that although participants learn and recall better in an online setup compared to in-person, the spacing effects were not as robust and did not confer any real advantage. These results are discussed in terms of advantages and disadvantages of the two procedures and the implications for online studies.

Acute Lower Gastrointestinal Hemorrhage

Diagnostic strategies for lower gastrointestinal bleeding include nuclear scintigraphy, mesenteric angiography and endoscopic evaluation of the lower gastrointestinal tract. Each method has inherent advantages and disadvantages. Nuclear scintigraphy is simple and noninvasive, but high rates of false localization have led most clinicians to insist on confirmation of the bleeding site by another method before considering surgical intervention. Angiography is very specific, but is invasive and not as sensitive as nuclear scintigraphy. Colonoscopy is sensitive and specific, and can offer therapeutic value but can be technically challenging in the face of acute lower gastrointestinal hemorrhage. These strategies and the evidence behind them are discussed.

In the face of so many taxes that Brazilians are obliged to pay and several times taxes that are not understood by ninety percent of the population, much is said about a tax reform that promises to transform many taxes into a single tax that will be collected throughout the country. country, therefore, simplifying the lives of thousands of Brazilians and companies that suffer from the collection of so many taxes. But will a change in the National Tax Code really bring benefits to society and companies? What will be its advantages and disadvantages in the face of the economic scenario we are experiencing today? It is also worth remembering that a real correction of existing distortions is necessary for the principles of equity and social justice to act. These are the questions proposed for reflection in this work, when dealing with the Brazilian tax system and its much-promised reform that aims to make it easier to understand what we really pay for our purchases and services.

How can we design technology that suits human cognitive needs? In this chapter, we review research on the effects of externalizing information on the interface versus requiring people to internalize it. We discuss the advantages and disadvantages of externalizing information. Further, we discuss some of our own research investigating how externalizing or not externalizing information in program interfaces influences problem-solving performance. In general, externalization provides information relevant to immediate task execution visibly or audibly in the interface. Thus, remembering certain task-related knowledge becomes unnecessary, which relieves working memory. Examples are visual feedback aids such as “graying out” nonapplicable menu items. On the contrary, when certain needed task-related information is not externalized on the interface, it needs to be internalized, stored in working memory and long-term memory. In many task situations, having the user acquire more knowledge of the structure of the task or its underlying rules is desirable. We examined the hypothesis that while externalization will yield better performance during initial learning, internalization will yield a better performance later. We furthermore expected internalization to result in better knowledge, and expected it to provoke less trial-and-error behavior. We conducted an experiment where we compared an interface with certain information externalized versus not externalizing it, and measured performance and knowledge. In a second session 8 months later, we investigated what was left of the participants’ knowledge and skills, and presented them with a transfer task. The results showed that requiring internalization can yield advantages over having all information immediately at hand. This shows that using cognitive findings to enhance the effectiveness of software (especially software with specific purposes) can make a valuable contribution to the field of human-computer interaction.

Mind And Brain

A historical overview is given of interdisciplinary work in physics and psychology by some of the greatest nineteenth-century scientists, and why the fields split, leading to a century of ferment before the current scientific revolution in mind-brain sciences began to understand how we autonomously adapt to a changing world. New nonlinear, nonlocal, and nonstationary intuitions and laws are needed to understand how brains make minds. Work of Helmholtz on vision illustrates why he left psychology. His concept of unconscious inference presaged modern ideas about learning, expectation, and matching that this book scientifically explains. The fact that brains are designed to control behavioral success has profound implications for the methods and models that can unify mind and brain. Backward learning in time, and serial learning, illustrate why neural networks are a natural language for explaining brain dynamics, including the correct functional stimuli and laws for short-term memory (STM), medium-term memory (MTM), and long-term memory (LTM) traces. In particular, brains process spatial patterns of STM and LTM, not just individual traces. A thought experiment leads to universal laws for how neurons, and more generally all cellular tissues, process distributed STM patterns in cooperative-competitive networks without experiencing contamination by noise or pattern saturation. The chapter illustrates how thinking this way leads to unified and principled explanations of huge databases. A brief history of the advantages and disadvantages of the binary, linear, and continuous-nonlinear sources of neural models is described, and how models like Deep Learning and the author’s contributions fit into it.

Mind's Eye

Unlike familiarity, recollection involves the ability to reconstruct mentally previous events that results in a strong sense of reliving. According to the reinstatement hypothesis, this specific feature emerges from the reactivation of cortical patterns involved during information exposure. Over time, the retrieval of specific details becomes more difficult, and memories become increasingly supported by familiarity judgments. The multiple trace theory (MTT) explains the gradual loss of episodic details by a transformation in the memory representation, a view that is not shared by the standard consolidation model. In this study, we tested the MTT in light of the reinstatement hypothesis. The temporal dynamics of mental imagery from long-term memory were investigated and tracked over the passage of time. Participant EEG activity was recorded during the recall of short audiovisual clips that had been watched 3 weeks, 1 day, or a few hours beforehand. The recall of the audiovisual clips was assessed using a Remember/Know/New procedure, and snapshots of clips were used as recall cues. The decoding matrices obtained from the multivariate pattern analyses revealed sustained patterns that occurred at long latencies (>500 msec poststimulus onset) that faded away over the retention intervals and that emerged from the same neural processes. Overall, our data provide further evidence toward the MTT and give new insights into the exploration of our “mind's eye.”

In the face of renewed interest in High-Speed Rail (HSR) projects, Ohio is one of several states seeking federal funding to relieve pressure on aging, overburdened highway infrastructure by constructing passenger rail routes between major cities. This paper evaluates the creation of a new rail route in Ohio’s 3-C Corridor utilizing GIS. The authors consider two primary cost factors in construction, slope and land cover, to generate alternative least-cost paths. To assess the importance of the cost factors, two separate paths are created using two different weighting methods for the land cover layer. The land cover is weighted first by difficulty of construction, and second by relative acquisition costs. These two paths are then compared against a path selected by the Ohio Hub Project which uses existing track lines, advantages and disadvantages of each are discussed.

Purpose The purpose of this paper is to introduce case-method teaching (CMT), its advantages and disadvantages for the process of organizational training within organizations, as well as to compare its advantages and disadvantages with current training methods. Design/methodology/approach The authors applied a systematic literature review to define, identify and compare CMT with current methods. Findings In CMT, participants get involved with real-world challenges from an action perspective instead of analyzing them from a distance. Also, different reactions of the participants to the same challenge aid instructors to identify the individual differences of participants toward the challenge. Although CMT is still not considered as a popular organizational training method, the advantages of CMT may encourage organizational instructors to further apply it. Improving the long-term memory, enhancing the quality of decision making and understanding the individual differences of individuals are the advantages of CMT. Research limitations/implications A lack of sufficient empirical researchers and the high cost of conducting this method may prevent practitioners to apply it. Originality/value The review suggested that CMT is able to bring dilemmas from the real world into training settings. Also, it helps organizations to identify the individual reactions before they make a decision.

The spacing effect (also known as distributed practice) refers to the finding that two or more learning opportunities that are spaced apart, or distributed, in time produce better learning than the same opportunities that occur in close succession. A number of theories have been proposed to account for the spacing effect. These include deficient processing, encoding variability, study-phase retrieval, and consolidation. According to the deficient processing account, learning opportunities that are spaced apart in time, compared to non-spaced or “massed” learning opportunities, are more likely to receive a learner’s full attention, ultimately leading to better quality learning. The encoding variability account proposes that spaced learning opportunities, because they are separated in time, are more likely to be associated with a number of different contextual cues that can benefit later memory for the information learned. Study-phase retrieval is based on the premise that retrieval benefits learning, and spaced learning opportunities are more likely than massed learning opportunities to involve retrieval of the previous learning experience. More recent evidence suggests that spacing learning opportunities across different days may benefit memory due to sleep-dependent neural consolidation processes. Research in authentic educational contexts shows that spacing benefits learning of a wide variety of materials, from basic facts to complex scientific concepts and skills. Regarding the practical question of when spaced learning opportunities should occur, the ideal scheduling of these opportunities depends upon how long the information needs to be remembered in the future, such that retention over longer intervals of time benefits most by longer spacing between repeated learning opportunities. Despite its promise for enhancing student learning, spacing can be challenging to implement in authentic educational contexts due to the intuitive notion that immediate repetition is better for learning, and the difficulties involved in setting a spaced study schedule in advance and adhering to it. To realize the full potential of spacing to enhance educational practices, future studies are needed that can measure implementation of spacing by students and teachers in real educational environments.

Melatonin (N-acetyl-5-methoxytryptamine) is a ubiquitous molecule present in animals and plants, and also in bacteria and fungi. In plants, it has an important regulatory and protective role in the face of different stress situations in which it can be involved, mainly due to its immobility. Both in the presence of biotic and abiotic stressors, melatonin exerts protective action in which, through significant changes in gene expression, it activates a stress tolerance response. Its anti-stress role, along with other outstanding functions, suggests its possible use in active agricultural management. This review establishes considerations that are necessary for its possible authorization. The particular characteristics of this substance and its categorization as plant biostimulant are discussed, and also the different legal aspects within the framework of the European Community. The advantages and disadvantages are also described of two of its possible applications, as a plant protector or biostimulant, in accordance with legal provisions.

AbstractThe superiority of spaced over massed learning is an established fact in the formation of long-term memories (LTM). Here we addressed the cellular processes and the temporal demands of this phenomenon using a weak spatial object recognition (wSOR) training, which induces short-term memories (STM) but not LTM. We observed SOR-LTM promotion when two identical wSOR training sessions were spaced by an inter-trial interval (ITI) ranging from 15 min to 7 h, consistently with spaced training. The promoting effect was dependent on neural activity, protein synthesis and ERKs1/2 activity in the hippocampus. Based on the “behavioral tagging” hypothesis, which postulates that learning induces a neural tag that requires proteins to induce LTM formation, we propose that retraining will mainly retag the sites initially labeled by the prior training. Thus, when weak, consecutive training sessions are experienced within an appropriate spacing, the intracellular mechanisms triggered by each session would add, thereby reaching the threshold for protein synthesis required for memory consolidation. Our results suggest in addition that ERKs1/2 kinases play a dual role in SOR-LTM formation after spaced learning, both inducing protein synthesis and setting the SOR learning-tag. Overall, our findings bring new light to the mechanisms underlying the promoting effect of spaced trials on LTM formation.
