The need to provide computers with the ability to distinguish the affective state of their users is a major requirement for the practical implementation of Affective Computing concepts. The determination of the affective state of a computer user from the measurement of some of his/her physiological signals is a promising avenue towards that goal. In addition to the monitoring of signals typical...

OBJECTIVE One symptom common to many persons with autism is a high arousal or anxiety level. This study investigated the effects of deep pressure on arousal and anxiety reduction in autism with Grandin's Hug Machine, a device that allows self-administration of lateral body pressure. METHOD Twelve children with autism were randomly assigned to either an experimental group (receiving deep press...

We examined individual differences in nonspecific electrodermal response (EDR) lability in terms of retest stability, cross-situational consistency, and heritability in a sample of 345 adult monozygotic and dizygotic twin pairs. We also examined the phenotypic and genetic relationships between EDR lability and speed of habituation of the specific EDR to a nonsignal stimulus. Individual variatio...

BACKGROUND Adaptive emotional responses are important in interpersonal relationships. We investigated self-reported emotional experience, physiological reactivity, and micro-facial expressivity in relation to the social nature of stimuli in individuals with schizophrenia (SZ). METHOD Galvanic skin response (GSR) and facial electromyography (fEMG) were recorded in medicated outpatients with SZ...

Electrodermal response (EDR) lability is a psychophysiological trait reflecting stable individual differences in electrodermal activation as indexed by frequency measures of phasic EDR activity. There is no consistent evidence that EDR lability reflects dispositional or clinical anxiety. However, EDR lability appears to be related to individual differences in the overt expression of emotional a...

BACKGROUND Leptospirosis is a disease which occurs worldwide but particularly affects tropical areas. Transmission of the disease is dependent on its excretion by reservoir animals and the presence of moist environment which allows the survival of the bacteria. METHODS AND FINDINGS A retrospective study was undertaken to describe seasonal patterns of human leptospirosis cases reported by the ...

Graph theoretical explorations of functional interactions within the human connectome, are rapidly advancing our understanding of brain architecture. In particular, global and regional topological parameters are increasingly being employed to quantify and characterize inter-individual differences in human brain function. Head motion remains a significant concern in the accurate determination of...

Gur and Sackeim (1979) argued that subjects deceived themselves when they failed to recognize their own voices on playback from a tape recorder. This claim is based primarily on the observation that subjects showed a heightened galvanic skin response when their own voices were present regardless of whether recognition took place. The authors suggest that even though subjects may not consciously...

In this paper with the help of different empirical models we have estimated the value of monthly average global solar irradiation for Ranchi (23.3500 ̊N, 85.3300 ̊E), a tropical location. The values of monthly average global solar radiation are calculated using the regression constants in the models (both linear and quadratic) suggested by: AngstromPrescott, Rietveld, Ogleman, Akinoglu, Glover, G...

The present investigation was designed to examine the effects of orienting task-controlled processing on electrodermal response and free recall at two delay intervals for 94 young, 49 young-old (age 55 to 70), and 61 old-old (age 71 to 85) individuals. Subjects were presented with a list of 25 words and performed one of the following tasks: semantic, nonsemantic, or passive listening, presented...
