The present experiment investigates in 'normal' subjects the relationship between personality characteristics (anhedonia versus hedonia) and the influence of the affective value of acoustic stimuli (positive, negative, neutral) on various electrophysiological indices reflecting either tonic activation or phasic arousal (EEG power spectra, contingent(More)
The objective of the present study was to determine whether an olfactory prime could modulate behavior and visual event-related potentials (ERPs) obtained in response to a visual stimulation representing female faces. More specifically, we tested the hypothesis that a pleasant odor could have effects on face perception: behavioral effects on subjective(More)
BACKGROUND The importance of genetic factors in the aetiology of manic-depressive illness (MDI) has been repeatedly confirmed and indicators of vulnerability to the illness in families with affective disorders are needed. Abnormal event-related potentials (ERP) may be markers of genetic vulnerability to mental illness. Long latency and low amplitude of P300(More)
To identify alterations in elementary cognitive operations according to dimensions of depression, two stages of information processing, namely the response choice and the motor preparation stages, were explored using an event-related potential paradigm in two subgroups of depressed patients (retarded and blunted affect versus anxious-agitated and impulsive)(More)
1. In the line of Zuckerman's studies on sensation seeking and optimal level of arousal, the authors hypothesized that high sensation seeking might be used to compensate for anhedonia due to basal arousal deficit. A population of interest was found with parachutists practicing skydiving, generally described as very high sensation seekers. 2. After clinical(More)
The relation between anhedonia and affective flattening was studied in 61 normal subjects and 61 major depressives. Affective flattening and anhedonia were defined by the following self-rating scales: Fawcett-Clark Pleasure Capacity Scale (FCPCS), Hardy Displeasure Capacity Scale (HDCS), FCPCS-PP (subscale of physical pleasure), and HDCS-PD (subscale of(More)
Anhedonia, the loss of the capacity of feeling pleasure, was first introduced at the end of the last century by a French psychologist, Ribot, and has been the object of much research, essentially in English, for the last decades, in schizophrenia, in depression, in schizoid disorders. After considering the problems of quantitative evaluation, we review the(More)
The Revised Social Anhedonia Scale (SAS) with 40 items (Eckblad et al., 1982) which studies the social dimension of anhedonia has been validated in the United-States (Mishlove & Chapman, 1985). However, no french translation and validation of this scale has been made to date. This work presents the french translation of the Social Anhedonia Scale and its(More)
Diabetes is one of the main causes of death in most developed countries. Both types of diabetes are spreading across the globe at an alarming rate, driving the condition to become one of the most challenging health problems of the 21st Century. Prevention is essential, and promoting a healthy lifestyle, early screening and investment in national programmes(More)
