Psychological Response to Sensory Stimulation by Environmental Stressors: Trait or State?

摘要: De facon a separer les caracteristiques du trait et de l'etat des reponses psychologiques aux stress sensoriels environnementaux, l'etude suivante fut entreprise en combinant experiences laboratoire sur le terrain. Fondee concept gene (Koelega, 1987) la premiere etape consista une enquete par questionnaire aupres 2300 citoyens Dusseldorf vivant dans quartiers avec circulation bruyante ou odeurs industrielles. cet echantillon basique, 150 sujets non-fumeurs furent selectionnes base environnementale plus moins forte, causee respectivement bruit 119 ces preclasses experimentalement exposes differents physico-chimiques comme indique ci-dessous: (1) pour (0, 65, 75db(A), (2) 50, 150ppm H2S) (3) fumee tabac l'atmosphere (ETS as 0,5, 10ppm CO). Chaque sujet expode un champ social seul niveau chaque condition experimentale; l'exposition dura heure. En d'un certain nombre mesures physiologiques (p. ex. clignement d'yeux, larmes, COHb, rythme cardiaque, respiration), plusieurs desagrement ressenti (gene) prises durant l'exposition. Il trouve que, termes variance exteme expliquee, fois (30%) pre-selection (10%) ont impact significatif (gene), retrouve tous stress. est conclu que induite stimulation sensorielle presente caraceristiques d'etat trait. In order to separate trait-and state-characteristics of psychological response sensory perceived environmental stressors, the present combined field/laboratory study was performed. Based on annoyance 1987). first step consisted questionnaire-based survey covering citizens living in areas either predominant traffic noise or industrial odour exposure. From this basic sample nonsmoking subjects were preselected basis high low degrees induced by odours, respectively. A total these preclassified experimentally exposed laboratory different physico-chemical stressors follows: To (0,65, 75dB(A) L); an odorous compound H2S); and tobacco smoke δCO). Each subject setting only one level each experimental condition; exposure duration hour. Apart from number physiological endpoints (e. g. eye blinks, lacrimation, heart rate, breathing), several measures discomfort (annoyance), taken during It found that, terms explained variance, both preselection had significant which generalised across stressors. is concluded that exhibits state- trait-characteristics.
