Turystyka miejsc pamięci - zwrot ku lokalności
2016
W pracy przedstawiono zjawisko podróżowania do miejsc pamięci ze szczególnym uwzględnieniem ich lokalnego charakteru. Za przykład do omówienia wybrano miejsca pamięci bezpośrednio związane z grupą zawodową górników, a dokładnie poświęcone ofiarom tragicznych wydarzeń w kopalniach. W ostatnich kilku latach wzrasta wśród turystów zainteresowanie górniczymi miejscami pamięci, co ma bezpośredni związek z funkcjonowaniem ścieżki turystyczno-krajoznawczej „Śladami ofiar górniczego stanu”, która powstała z inicjatywy członków Koła Kolarskiego „Sokół” Oddziału PTTK Radlin.
Mejorando la comprensión lectora: Desde la intervención metacognitiva en estrategias a la intervención en los procesos ejecutivos de la memoria opera…
2013
Many students may read fluently but have difficulties constructing meaning from texts. Difficulties with reading comprehension have many implications at school. In particular, problems understanding texts interfere with studying and learning from text. Reading comprehension has improved in the last 30 years focusing on intervention programs that work with strategies in which metacog-nition plays a crucial role. However, recent years have seen relevant advances in the study of the relationship between working memory (WM), particularly executive processes, and reading comprehension. In this paper, we present how the last 20 years of our research has evolved regarding metacognitive interventio…
Sana-assosiaatioverkkojen koheesion yhteys ryhmädynamiikkaan
2016
Tässä pilottitutkimuksessa selvitettiin sana-assosiaatioiden koheesiota ryhmissä. Tarkoituksena oli selvittää, löytyykö yhtenäisyyttä ryhmän keskinäisen toimeen tulemisen välillä ja sen suhteen, kuinka ryhmät assosioivat sanoja. Assosiaatioiden koheesion mittaamisessa käytettiin pohjatietona muistiteorioita ja verkkoteoriaa. Koehenkilöt olivat Jyväskylän yliopistossa järjestetyn kurssin oppilaita, jotka jakaantuivat ryhmiin. Kurssin aluksi ensimmäiset assosiaatiotehtävät teetettiin oppilailla. Kurssin loputtua he tekivät kaksi uutta tehtävää sekä ensimmäiset tehtävät, jotta osalle tehtävistä saatiin kaksi eri mittauspistettä. Kurssin oppilaat sekä vetäjät täyttivät kurssin loputtua ryhmän k…
Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication
2016
The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with com…
Sustained attention required for effective dimension-based retro-cue benefit in visual working memory
2023
In visual working memory (VWM) tasks, participants’ performances can be improved through the use of dimension-based retro-cues, which direct internal attention to prioritize a particular dimension (e.g., color or orientation) of VWM representations even after the stimuli disappear. This phenomenon is known as the dimension-based retro-cue benefit (RCB). The present study investigates whether sustained attention is required for the dimension-based RCB by inserting interference or interruption between the retro-cue and the test array to distract attention. We tested the effects of perceptual interference or cognitive interruption on dimension-based RCB when the interference (Experiments 1 and…
视觉工作记忆存储的表征单位 [The Representation Unit of Visual Working Memory]
2022
The visual working memory is a limited storage system in which people could flexibly process the representations to complete the task. Among studies on the capacity of visual working memory, the representation unit is a prior subject. Previous research employs the change-detection paradigm and the recall paradigm to explore the nature of representations when features of diverse dimensions and different-level features of the same dimension are stored in the visual working memory. These studies elicit two binary hypotheses: the object-based representation hypothesis backs that those diverse features are bound on the object and form a whole, while the feature-based representation hypothesis su…
Visual working memory resource allocation mechanism in consolidation and maintenance phase
2018
Visual working memory (VWM) is a system for actively maintaining visual information to meet the needs of an ongoing task. It allows individuals to store visual input information from a complex outside environment and provides storage space as an information buffer platform to help integrate information into a continuous visual experience. This research examined the consolidation and maintenance phase of the VWM resource allocation mechanism. Four aspects of this issue were investigated. First, resource allocation in VWM consolidation was investigated for different materials, and it was determined whether VWM resources were allocated in a serial manner for orientation materials but in a limi…
The mechanism of retro-cue effect in visual working memory : Cognitive phase separation
2020
Retro-cue effect (RCE) refers to the phenomenon that individuals can use retro-cues to improve their visual working memory (VWM) performance of target items after memory stimuli disappear. To explain the mechanism of RCE in VWM, five different hypotheses have been proposed by previous studies: the hypothesis of enhancing target representations, the hypothesis of forgetting non-target representations, the hypothesis of preventing memory degradation, the hypothesis of preventing interference from probe array and the hypothesis of cognitive phase separation. Although RCE has been repeatedly observed in previous studies, the mechanism of RCE remains unclear. In this study, we conducted three ex…
视觉工作记忆中回溯线索效应的影响因素 [The Influencing Factors of Retro-Cue Effect in Visual Working Memory]
2022
The visual working memory is a temporary storage system, which encodes, maintains and retrieves visual information. The researchers have found that adding retro-cues to the maintenance phase of memory leads to changes in participants’ memory performance, which is the retro-cue effect. The magnitude of the retro-cue effect is not set in stone, but changes with the changes of its influencing factors. However, there is no study to summarize the influencing factors of the retro-clue effect. This paper looked into the articles related to the study of the retro-cue effect and summarized the influencing factors of the retro-cue effect: memory items, maintenance interval time, interference in maint…
Negative emotional state modulates visual working memory in the late consolidation phase
2020
Although a considerable literature has grown up around the interactions between emotional state and visual working memory (VWM) performance, the mechanism underlying the impact of the negative emotional state on VWM remains unclear. The present study aimed to test whether the influence of emotional state is related to the early phase or late phase of VWM consolidation process. Across three experiments, we found that the negative emotional state did not affect VWM performance when the presentation time of stimuli was short. However, when the presentation time was long, the negative emotional state increased the VWM precision and reduced the VWM number. According to the two-phase model propos…
