Electrodermal Response Lability-Stability: Individual Difference Correlates

Personality and Electrodermal Response Lability: An Interpretation

“…For example, Landis (1932) reported that delinquent boys who were overtly distressed while performing a difficult motor task emitted fewer nonspecific EDRs during the task than did less expressive subjects. Jones (1950Jones ( , 1960 subsequently confirmed the trade-off between EDR lability and emotional expressiveness and also identified a relationship between EDR lability and characteristics reflecting the contemporary conception of agreeableness vs. antagonism (Crider 1993). As part of a longitudinal investigation of adolescent development, Jones assessed EDR lability and personality characteristics in a mixed gender sample of 100 subjects on multiple occasions over a 6-year period.…”

“…Lacey and Lacey subsequently reported that individual differences in the rate of nonspecific EDR emission were stable over a 48-h. retest interval and consistent across different observational contexts. The findings of these two influential studies have been amply confirmed by subsequent investigations (Crider 1993;Crider et al 2004). EDR lability can be regarded as a psychophysiological trait reflecting individual differences in electrodermal activation as measured by the frequency of occurrence of either nonspecific or specific EDR activity.…”

“…EDR labiles show faster simple and choice reaction time than EDR stabiles and superior performance on vigilance tasks requiring the detection of infrequent signals over an extended monitoring period (Crider 1993). EDR lability is therefore differentially associated with task performance depending on the cognitive demands imposed.…”

“…This hypothesis is an extrapolation to individual differences of the well known sensitivity of electrodermal activity to threat or signals of threat (Bradley 2000). Despite occasional confirmations, however, a substantial number of studies have failed to find any consistent relationship between EDR lability and self-report anxiety measures such as Taylor Manifest Anxiety and similar devices (O'Gorman 1983;Crider 1993). More recent studies have reported null findings for conceptually related self-report measures, including social anxiety (Mauss et al 2003) and behavioral inhibition (Brenner et al 2005).…”

Chronic pain and electrodermal activity

“…Le NED et la fréquence des FS sont des paramètres toniques. L'AED peut avoir valeur de trait individuel stable : la labilité (antonyme : stabilité) est caractérisée par une fréquence élevée de FS, souvent associée à un défaut d'habituation des RED en cas de stimulations répétées [11,12]. Par ailleurs, l'AED peut être reliée à certains désordres émotionnels, dont la dépression.…”
