Effects of Online Attentional Bias Modification on Coronavirus Anxiety
Background: The negative impacts of the Coronavirus Disease 2019 (COVID-19)outbreak on public mental health are enhancing the number of individuals requiring psychotherapy. Besides, anxiety is becoming more frequent than any other mental health issue among individuals. Similar to other anxiety types, coronavirus anxiety is associated with elevated attentional bias. The present study aimed to ex...
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...
متن کاملEffects of Stimulus-Driven and Goal-Directed Attention on Prepulse Inhibition of Brain Oscillations
OBJECTIVE Prepulse inhibition (PPI) is an operational measure of sensory gating. PPI of cortical response to a startling pulse is known to be modulated by attention. With a time-frequency analysis, we sought to determine whether goal-directed and stimulus-driven attention differentially modulate inhibition of cortical oscillations elicited by a startling pulse. METHODS An electroencephalogram...
متن کاملEffects of aberrant gamma frequency oscillations on prepulse inhibition.
Emerging literature implicates abnormalities in gamma frequency oscillations in the pathophysiology of schizophrenia, with hypofunction of N-methyl-D-aspartate (NMDA) receptors implicated as a key factor. Prepulse inhibition (PPI) is a behavioural measure of sensorimotor gating, which is disrupted in schizophrenia. We studied relationships between ongoing and sensory-evoked gamma oscillations a...
