- Neuroscience
- Psychophysiology
- Cognitive Psychology
Background
- The study combines working memory and threat of shock paradigms.
- It addresses key questions about anxiety and cognition.
- This method can be adapted for various cognitive tasks.
- Electrophysiological measures are used to assess responses.
Purpose of Study
- To examine the impact of anxiety on cognitive performance.
- To measure the startle response under different cognitive loads.
- To investigate how anxiety influences working memory tasks.
Methods Used
- Participants undergo skin conductance and heart rate monitoring.
- Electrodes are placed to measure startle responses.
- Shock calibration is performed to determine discomfort levels.
- Participants complete tasks while their physiological responses are recorded.
Main Results
- Participants show varying accuracy and reaction times based on cognitive load.
- Anxiety levels influence performance during the tasks.
- Startle responses are larger during low load conditions.
- Data types include accuracy, reaction time, and anxiety-potentiated startle.
Conclusions
