“…The initial hypothesis that individual variability in dopamine functioning represents a neurobiological substratum for the psychoticism personality dimension (Lester, 1989) was provided with biological evidence from studies on receptor binding with single-photon emission computed tomography (Gray et al,1994) and replicated elsewhere with the use of both functional magnetic resonance imaging and evoked potentials (Kumari et al, 2004;O'Gorman et al, 2006;Colzato et al, 2009;Papageorgiou et al, 2010).…”

We present results from a cross-sectional study of the entire adolescent student population aged 14 to 18 years of the island of Kos, on the correlates between personality, illicit chemical substance use, and Internet abuse. Results demonstrate that adolescents who have used illicit substances and are abusing the Internet as well appear to share some common personality characteristics, namely those that are classified under the label of "psychoticism" in the Eysenck's personality model. An increase in the severity of pathological Internet use has been linked to increased chances of having used an illicit substance. Taking into account any common personality attributes, Internet addiction can still be useful as a predictor variable for substance use experiences. Future research should attempt to verify any biological common factors between chemical substances use and Internet abuse. Targeting the adolescent population that engages in increased Internet use may be of benefit for drug abuse prevention programs.

“…4.2.1 P50 component with tactile sensation of silk fabrics. So far, most of researches on P50 component focus on visual and auditory tests (Charalabos et al, 2010;Hauthal et al, 2015;Popovich and Staines, 2015;Vlcek et al, 2014;Marshall Peter et al, 2004;Joos et al, 2014). But As shown in Figure 6, the maximum amplitude and latency of P50 evoked by all participants' touch on the samples were extracted.…”

PurposeIn this paper, the brain potential changes caused by touching fabrics for handle evaluation were recorded by event related potential (ERP) method, compared with subjective evaluation scores and physical index of KES, explore the cognitive mechanism of the transformation of tactile sensation into neural impulses triggered by subtle mechanical stimuli such as material, texture, density and morphology in fabrics. By combining subjective evaluation of fabric tactile sensation, objective physical properties of fabrics and objective neurobiological signals, explore the neurophysiological mechanism of tactile cognition and the signal characteristics and time process of tactile information processing.Design/methodology/approachThe ERP technology was first proposed by a British psychologist named Grey Walter. It is an imaging technique of noninvasive brain cognition, whose potential changes are related to the human physical and mental activities. ERP is different from electroencephalography (EEG) and evoked potentials (EP) on the fact that it cannot only record stimulated physical information which is transmitted to brain, but also response to the psychological activities which related to attention, identification, comparison, memory, judgment and cognition as well as to human’s neural physiological changes which are caused by cognitive process of the feeling by stimulation.FindingsAccording to potential changes in the cerebral cortex evoked by touching four types of silk fabrics, human brain received the physical stimulation in the early stage (50 ms) of fabrics handle evaluation, and the P50 component amplitude showed negative correlation with fabric smoothness sensations. Around 200 ms after tactile stimulus onset, the amplitude of P200 component show positive correlation with the softness sensation of silk fabrics. The relationship between the amplitude of P300 and the sense of smoothness and softness need further evidence to proof.Originality/valueIn this paper, the brain potential changes caused by touching fabrics for handle evaluation were recorded by event related potential (ERP) method, compared with subjective evaluation scores and physical index of KES, the results shown that the maximum amplitude of P50 component evoked by fabric touching is related to the fabrics’ smoothness and roughness emotion, which means in the early stage processing of tactile sensation, the rougher fabrics could arouse more attention. In addition, the amplitude of P200 component shows positive correlation with the softness sensation of silk fabrics.
