Investigating task-based synchronous computer-mediated communication (SCMC) interaction has increasingly received scholarly attention. However, studies have focused on negotiation of meaning and the quantity, focus resolution language related episodes (LREs). This study aims to broaden our understanding role audio, video, text SCMC conditions by additionally examining second (L2) learners’ leve...

The problem of radiationless Förster energy transfer between a donor and an acceptor molecule is studied in the vicinity of a metallic nanorice. Using a recently formulated effective medium theory, the modified dipole–dipole interaction between the molecules in the vicinity of a spheroidal metallic nanoshell can be easily formulated, from which huge enhancement of the energy transfer rate is ob...

This research investigated effects of task types on the acquisition of English voice onset time (VOT) by Japanese university students with a short-term but intensive exposure to academic English. The data were collected from 11 Japanese learners of English as a foreign language (EFL) receiving English-medium instruction at a university level, 11 Japanese EFL learners enrolled in regular EFL cou...

This paper presents a study on laser intensity distributions where field enhancements occur due to scattering by spherical sapphire particles and under conditions of different wavelengths and substrate media. A sapphire micro particle concept is employed to determine the effects of light–particle interaction with a particle refractive index approaching 2 (n ≤ 2). Mie scattering software is used...

Two methods are utilized to study the relaxation behaviour and molecular motion in solutions of free radicals in toluene: the investigation of longitudinal and transversal solvent proton relaxation at a properly chosen frequency (48 MHz), and the determination of enhancement factors of the dynamic proton polarization over a large frequency range. The temperature dependence of the quantities con...

In the crossmodal signals paradigm (CSP) participants are instructed to respond to a set of stimuli from different modalities, presented more or less simultaneously, as soon as a stimulus from any modality has been detected. In the focused attention paradigm (FAP), on the other hand, responses should only be made to a stimulus from a pre-defined target modality and stimuli from non-target modal...

OBJECTIVES There is some discrepancy in the results regarding emotional enhancement of memory (EEM) in Alzheimer's disease (AD). Some studies report better retrieval of emotional information, especially positive, than neutral information. This observation is similar to the positivity effect reported in healthy older adults. It was suggested that this effect is due to privileged, deeper and more...

Emotion identification is beginning to be considered as an essential feature in human-computer interaction. However, most of the studies are mainly focused on facial expression classifications and speech recognition and not much attention has been paid until recently to physiological pattern recognition. In this paper, an integrative approach is proposed to emotional interaction by fusing multi...

We examined emotional memory enhancement (EEM) for negative and positive pictures while manipulating encoding and retrieval conditions. Two groups of 40 participants took part in this study. Both groups performed immediate implicit (categorization task) and explicit (recognition task) retrieval, but for one group the tasks were preceded by incidental encoding and for the other group by intentio...

Past studies beginning with Jackson et al. [Jackson, D.C., Malmstadt, J.R., Larson, C.L., Davidson, R.J., 2000. Suppression and enhancement of emotional responses to unpleasant pictures. Psychophysiology 37 (4), 515-522.] document increases and decreases in emotionally-potentiated startle by way of instructing participants to enhance or suppress their emotional responses to symbolic sources of ...
