Load-dependent alpha suppression is related to working memory capacity for numbers

2022

Alpha suppression is proposed to reflect a surge in cortical excitability to enhance stimulus processing in working memory. The attenuated state of alpha might reflect the prioritisation of behaviourally relevant information, making it a proxy for working memory functioning. Despite the growing interest in utilising the advancement of brain-based measures to evaluate individuals’ cognitive processes, there was a lack of consistent evidence on the relationship between alpha suppression and working memory performance. To investigate whether interindividual differences in alpha suppression might be related to variability in working memory capacity, we recorded participants’ electroencephalogra…

CA3–CA1 long‐term potentiation occurs regardless of respiration and cardiac cycle phases in urethane‐anesthetized rats

2023

Breathing and heartbeat synchronize to each other and to brain function and affect cognition in humans. However, it is not clear how cardiorespiratory rhythms modulate such basic processes as synaptic plasticity thought to underlie learning. Thus, we studied if respiration and cardiac cycle phases at burst stimulation onset affect hippocampal long-term potentiation (LTP) in the CA3–CA1 synapse in urethane-anesthetized adult male Sprague–Dawley rats. In a between-subjects design, we timed burst stimulation of the ventral hippocampal commissure (vHC) to systole or diastole either during expiration or inspiration and recorded responses throughout the hippocampus with a linear probe. As classic…

Rossiâ - Polʹša: nesovpadenie pamâtej. Lingvističeskij aspekt

2017

„Memory turn” in the humanities allows to approach old problems from a new perspective. The author argues that the sphere of complicated Russian-Polish relations should be presented as a conflict between two distinct collective memories. The author considers “memory” as strictly interconnected with so called “non-memory” (i.e. as set of facts not related to memory or superseded by it). In principle, collective memory / non-memory can be subjected to linguistic analysis because it is verbalized and therefore it has its different verbal exponents. The author refers back to his concept of “mental geography” developed 20 years ago and argues that a multi-stage process of mapping two national me…

Lattice Boltzmann Simulations at Petascale on Multi-GPU Systems with Asynchronous Data Transfer and Strictly Enforced Memory Read Alignment

2015

The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently general-purpose graphics processing units have become accessible as high-performance computing resources at large-scale. We report on implementing a lattice Boltzmann solver for multi-GPU systems that achieves 0.69 PFLOPS performance on 16384 GPUs. In addition to optimizing the data layout on the GPUs and eliminating the halo sites, we make use of the possibility to overlap data transfer between the host CPU and the device GPU with computing on the GPU. We simulate flow in porous media and measure both strong and weak scaling performance with the emphasis being on a large scale…

Visual Distraction Effects of In-Car Text Entry Methods

2017

Three text entry methods were compared in a driving simulator study with 17 participants. Ninety-seven drivers’ occlusion distance (OD) data mapped on the test routes was used as a baseline to evaluate the methods’ visual distraction potential. Only the voice recognition-based text entry tasks passed the set verification criteria. Handwriting tasks were experienced as the most demanding and the voice recognition tasks as the least demanding. An individual in-car glance length preference was found, but against expectations, drivers’ ODs did not correlate with incar glance lengths or visual short-term memory capacity. The handwriting method was further studied with 24 participants with instru…

LA PERCEZIONE DEL TEMPO

2005

This paper reviews psychological research on time perception. In view of the wastness of this topic, we only focus on temporal memory, i.e. time duration estimation. We will present the main psychological theories, elaborated in the first laboratories.Finally, both the current cognitivist and chronobiological models and theories will be introduced.

Il Belice prima e dopo il 1968 attraverso le iconografie

2014

Il saggio presenta come l' intero territorio della valle del Belice abbia cambiato identità dopo il terremoto del 1968. Attraverso le iconografie (fotografie, disegni) di architetture esistite e poi distrutte. The 1968 earthquake in western Sicily is a break point in the history of a territory rich and layered. The journalism has mainly dealt with the case Gibellina, but in reality is the entire geographical area to have changed relationships and vocations. The iconography and photographs can witness the difference that occurred within a few years. In fact, the contemporary architecture linked to the reconstruction is only one of the parameters suitable to interpret mutations identity of pl…

’Civilising’ the Transitional Generation: The Politics of Civic Education in Post-Communist Romania

2019

Abstract The paper examines the introduction of civic education in post-communist Romania as an educational means of civilising in a democratic ethos the children of the transition. Particularly close analytical attention is paid to a) the political context that shaped the decision to introduce civic education, b) the radical changes in both content and end purpose of civics brought about by educational policies adopted for accelerating the country’s efforts of integrating into the Euro-Atlantic structures (NATO and the European Union), and c) the actual consequences that these educational policies betting on civics have had on the civic values expressed by Romanian teenagers. The analysis …

Pamięć w poemacie Tomasza Różyckiego "Dwanaście stacji"

2014

Pamięć w poemacie Dwanaście stacji Tomasza Różyckiego pełni nie tylko funkcję nośnika przeszłości. Jest również kreatorem niezwykłej podróży, którą odbywa główny bohater – nazwany przez narratora Wnukiem. Poprzez wspomnienia przenosi się on do czasów dzieciństwa, kiedy centrum jego świata stanowiła niewielka kamienica babci. Po latach przypomina sobie zdarzenia z nią związane – zapomniane przedmioty, niekończące się zabawy, smaki, zapachy, obrazy tamtych lat. Szuka tej przeszłości i na nowo ją interpretuje. Jego wyprawie towarzyszy rodzina, która jest zarówno inspiratorem, jak i motywatorem. Wnuk dzieli pamięć z innymi. Członkowie rodziny razem budują pewien dyskurs zawarty w poemacie. W pr…
