Secondary Students’ Sensory Preferences and Their Influence on Science Academic Achievement

2021

Evidence has been found that some students seem to have learning obstacles associated with particular sensory preferences when dealing with instructional materials. Therefore, knowing students’ sensory preferences could help teachers improve instructional resources. Our objectives were: (1) to describe Secondary students’ sensory preferences according to gender and age; (2) to analyse the possible association between students’ sensory preferences and their general academic achievement in science. We conducted a synchronic, cross-sectional descriptive study in a sample of 582 male and female students from 7th to 11th grade using the VARK questionnaire. There was a significant predominance of…

Behavioural thresholds of blue tit colour vision and the effect of background chromatic complexity

2020

Vision is a vital attribute to foraging, navigation, mate selection and social signalling in animals, which often have a very different colour perception in comparison to humans. For understanding how animal colour perception works, vision models provide the smallest colour difference that animals of a given species are assumed to detect. To determine the just-noticeable-difference, or JND, vision models use Weber fractions that set discrimination thresholds of a stimulus compared to its background. However, although vision models are widely used, they rely on assumptions of Weber fractions since the exact fractions are unknown for most species. Here, we test; i) which Weber fractions in lo…

Mild Dissonance Preferred Over Consonance in Single Chord Perception

2016

Previous research on harmony perception has mainly been concerned with horizontal aspects of harmony, turning less attention to how listeners perceive psychoacoustic qualities and emotions in single isolated chords. A recent study found mild dissonances to be more preferred than consonances in single chord perception, although the authors did not systematically vary register and consonance in their study; these omissions were explored here. An online empirical experiment was conducted where participants ( N = 410) evaluated chords on the dimensions of Valence, Tension, Energy, Consonance, and Preference; 15 different chords were played with piano timbre across two octaves. The results sugg…

Modern Tendencies in Changing the Consumers’ Preferences

2014

Abstract In the middle of globalization era, when consumers have at their disposal more and more prosperous livelihood, when technology is more and more present, when everyone look for the newest and the most modern thing, food sector represents an exception. They try to establish links which go beyond the product itself and pay a special attention to the story behind the product. They want to know about the production site, the origin of ingredients, the persons involved in the production process. This is why the current consumers are looking for unique, sensorial experiences which, according to them, can be found only in original, simple, traditional products. The simplicity and authentic…

Pathomorphology of hereditary sensory neuropathies

1995

Currently, the hereditary sensory neuropathies (HSN) — because of the involvement of the autonomic system recently called HSAN — comprise types I–V predicated on clinical differences. This classification of HSAN I–V seems to be uncontested, at the present time. Morphologically, individual forms I–V only differ in the non-specific loss or lack of myelinated and unmyelinated nerves in varying degrees in that in HSAN II large myelinated axons are most affected, in HSAN IV unmyelinated axons are almost absent; but each HSAN is considered an axonal type of neuropathy. Early onset, slow or no progression of the neuropathic process, and little or no evidence of ongoing degeneration suggest maldeve…

Delayed feedback of somato-motor cortex activations modulates finger tapping results in real-time functional MR imaging

Abstract Proprioceptive paired-stimulus paradigm was used for 30 children (10–17 years) and 21 adult (25–45 years) volunteers in magnetoencephalography (MEG). Their right index finger was moved twice with 500-ms interval every 4 ± 25 s (repeated 100 times) using a pneumatic-movement actuator. Spatial-independent component analysis (ICA) was applied to identify stimulus-related components from MEG cortical responses. Clustering was used to identify spatiotemporally consistent components across subjects. We found a consistent primary response in the primary somatosensory (SI) cortex with similar gating ratios of 0.72 and 0.69 for the children and adults, respectively. Secondary responses with…

Optical biosensor-based characterization of anti-double-stranded DNA monoclonal antibodies as possible new standards for laboratory tests.

2009

The serum determination of circulating anti-double-stranded (ds)DNA autoantibodies is a routine measure for the laboratory diagnosis of systemic lupus erythematosus. Since available assays differ substantially and no feasible calibrator is available, the aim of this study was to evaluate a recently introduced surface plasmon resonance (SPR) biosensor chip for binding studies between dsDNA and anti-dsDNA autoantibodies and to demonstrate its usefulness for the characterization of new monoclonal antibody (mAb) standards and standardization of assays. We characterized two human and one murine monoclonal anti-dsDNA antibodies by measuring the kinetic on- and off-rates using the biosensor and ca…
