The two-stage process in visual working memory consolidation
2019
AbstractTwo hypotheses have been proposed to explain the formation manner for visual working memory (VWM) representations during the consolidation process: an all-or-none process hypothesis and a coarse-to-fine process hypothesis. However, neither the all-or-none process hypothesis nor the coarse-to-fine process hypothesis can stipulate clearly how VWM representations are formed during the consolidation process. In the current study, we propose a two-stage process hypothesis to reconcile these hypotheses. The two-stage process hypothesis suggests that the consolidation of coarse information is an all-or-none process in the early consolidation stage, while the consolidation of detailed infor…
Could selection tests detect the future performance of descriptive panellists ?
1996
Abstract This paper discusses the appropriateness of screening tests in explaining descriptive panellist performances. It is based on a case study aimed at forming a descriptive panel capable of flavour profiling Camembert cheeses. Eighteen subjects were selected using four sensory tasks evaluating smell sensitivities, olfactory knowledge, odour memory and descriptive ability. Three additional tests were proposed during the 45 hour training to evaluate the recognition memory for odours, the concentration and the verbal creativity abilities. Panellist performances were determined on repeatability and discrimination abilities, and on the complexity of the individual sensory space. Some signif…
fMRI-activation patterns in the detection of concealed information rely on memory-related effects
2012
Recent research on potential applications of fMRI in the detection of concealed knowledge primarily ascribed the reported differences in hemodynamic response patterns to deception. This interpretation is challenged by the results of the present study. Participants were required to memorize probe and target items (a banknote and a playing card, each). Subsequently, these items were repeatedly presented along with eight irrelevant items in a modified Guilty Knowledge Test design and participants were instructed to simply acknowledge item presentation by pressing one button after each stimulus. Despite the absence of response monitoring demands and thus overt response conflicts, the experiment…
Task-Modulated Corticocortical Synchrony in the Cognitive-Motor Network Supporting Handwriting
2019
Abstract Both motor and cognitive aspects of behavior depend on dynamic, accurately timed neural processes in large-scale brain networks. Here, we studied synchronous interplay between cortical regions during production of cognitive-motor sequences in humans. Specifically, variants of handwriting that differed in motor variability, linguistic content, and memorization of movement cues were contrasted to unveil functional sensitivity of corticocortical connections. Data-driven magnetoencephalography mapping (n = 10) uncovered modulation of mostly left-hemispheric corticocortical interactions, as quantified by relative changes in phase synchronization. At low frequencies (~2–13 Hz), enhanced …
Linguistic Bias Modulates Interpretation of Speech via Neural Delta-Band Oscillations.
2017
Language comprehension requires that single words be grouped into syntactic phrases, as words in sentences are too many to memorize individually. In speech, acoustic and syntactic grouping patterns mostly align. However, when ambiguous sentences allow for alternative grouping patterns, comprehenders may form phrases that contradict speech prosody. While delta-band oscillations are known to track prosody, we hypothesized that linguistic grouping bias can modulate the interpretational impact of speech prosody in ambiguous situations, which should surface in delta-band oscillations when grouping patterns chosen by comprehenders differ from those indicated by prosody. In our auditory electroenc…
A New Unsupervised Neural Network for Pattern Recognition with Spiking Neurons
2006
In this paper we propose a three-layered neural network for binary pattern recognition and memorization. Unlike the classic approach to pattern recognition, our net works organizing itself in an unsupervised way, to distinguish beetween different patterns or to recognize similar ones. If we present a binary input to the first layer, after some time steps we could read the output of the net in the third layer, as one and only one neuron activating with high firing rate; the middle layer will act as a generalization layer, i.e. similar pattern will have similar (or the same) representation in the middle layer. We used learning algorithms inspired from other works or from biological data to ac…
Problems of coding stereo images in human memory
2010
This paper discusses the memorization and recall by man of a sequence of planar or stereoscopic images, including six frames that contain a planar strip (8×8 positions of the stimulus) or a volume strip (8×4×2 positions). At the recall stage, the subject chose between the stimulus and three distractors in each frame. It is shown that the times for recognition and recall are less for volume stimuli, while the percent of correct responses is greater for planar stimuli. For volume stimuli, the distribution of errors depends on the disparity between the target and the selected distractor. A model based on a heteroassociative neural network reproduces the error distribution for planar but not fo…
Design and Style of Cultural and Media Studies Textbooks for College Students
2014
This paper uses the conceptual framework of multimodal discourse analysis in order to investigate the dominant styles and designs in selected Cultural and Media Studies (CMS) university textbooks. For many EFL students who major in philology, CMS courses are obligatory and thus constitute a type of content and language integrated learning (CLIL). The data from a description and evaluation of four popular textbooks indicate that there is a discernible move away from traditional literacy towards visuality and orality in textbook design and style. This tendency is evident in the use of segmentation and listing in composition, dialogic layouts and informal registers in exposition and visual aid…
Estrategias de aprendizaje en educación superior en un modelo curricular por competencias
2014
ResumenLas estrategias de aprendizaje utilizadas por los estudiantes afectan las metas de un modelo educativo; inciden en el tipo de aprendizaje que se pretende lograr. En el análisis sobre estas estrategias que utilizan los alumnos de las carreras de educación superior, cuyo modelo institucional está centrado en el estudiante con el enfoque por competencias, se encontró que la mitad de ellos se auxilian de tácticas acordes con este modelo como el ensayo, la elaboración, las metacognitivas, la autorreguladora, la autoevaluación y el apoyo afectivo; los demás combinan estrategias que conllevan a la memorización con las del aprendizaje significativo; las que menos utilizan son las de organiza…
Implicit learning and implicit memory in moderate to severe memory disorders
2010
Numerous experimental psychology studies have established firmly that important parts of the human cognitive process operate automatically without the conscious or explicit control of the subjects (9). Such processes can concern memorization of episodes from life in a way that will subsequently have an implicit influence on our behavior (such as decision-making or reaction time). They can equally assist acquisition of more complex knowledge from our surroundings, by the automatic capture of the statistical regularities found in them (see Chapter “Introducing implicit learning: from the laboratory to the real life”, E. Bigand and C. Delbe). This is the way, for example, that a baby learns to…
