Prepulse-elicited startle in prepulse inhibition.
BACKGROUND Prepulse inhibition (PPI) has become a major experimental paradigm in the study of psychiatric disorders. In this study, a potential confound in measurement and interpretation of PPI, namely startle reactions to so-called "nonstartling" prepulses, was examined. METHODS Prepulses of 80, 85, and 90 dB(A) were presented on their own or followed by a pulse of 115 dB(A) (lead interval: ...
متن کاملPrepulse facilitation and prepulse inhibition in schizophrenia patients and their unaffected siblings.
BACKGROUND Deficits in schizophrenia patients and their first-degree relatives have been reported in prepulse inhibition (PPI), a phenomenon that measures an early stage of information processing (sensorimotor gating). It is less clear whether these information processing deficits extend to prepulse facilitation (PPF), which measures a later stage of generalized alerting or orienting. METHODS...
متن کاملThe protective effects of brief mindfulness meditation training.
Mindfulness meditation has gained a great deal of attention in recent years due to the variety of physical and psychological benefits, including improved working memory, decreased mind wandering and reduced impact of stress on working memory. The current study examined a 1-week at home mindfulness meditation intervention compared to an active control intervention. Results suggest that mindfulne...
متن کاملEffects of cigarette smoking on prepulse inhibition, its attentional modulation, and vigilance performance.
Startle eyeblink modification was measured during a degraded stimulus continuous performance test following both smoking and overnight abstinence among student smokers to measure the effects of smoking on both early and late attentional processes. A group of nonsmokers was tested twice without nicotine manipulation. A startling noise was presented either 240 or 1200 ms following target and nont...
متن کاملAutomatic and controlled attentional processes in startle eyeblink modification: effects of habituation of the prepulse.
The effect of prehabituation of the prepulse on startle eyeblink modification was studied in two experiments. In Experiment 1, college student participants were either prehabituated or nonhabituated to a tone that served as a prepulse in a startle modification passive attention paradigm. Neither short lead interval (60 and 120 ms) prepulse inhibition (PPI) nor long lead interval (2,000 ms) prep...
