Project Title: Event-Related Potentials and Cognitive Mechanisms in Specific Health Risk Behaviors
Phase 1
Development of Psychometric Measures
- 1. Development/Standardization of Psychometric Measures
- Developed and standardized HeRBs Gratification Control Inventory
- Standardized Health Risk Behavior Inventory (Irish, 2011)
- 2. Programmed experimental measures in MATLAB for assessing different variables
- Response Inhibition: Flanker task
- Orientation Bias: Approach-Avoidance Task
Phase 2
Psychophysiological Exploration
- Exploration into electrophysiological mechanisms involved in approach-avoidance tendencies towards alcohol among heavy drinkers.
- 1. EEG recording during approach-avoidance task among heavy drinkers
- 2. Analysis of Behavioral and ERP patterns.
- Results
- 1. Significant interation between approach-avoidance tendency and group (alcohol and control)
- 2. Significant modulation of ERP activity at O1, O2, Oz, and Fz during early stages of processing by approach-avoidance tendency across groups.
- 3. Significant modulation of late ERP activity at P4, F7, and F8 reflecting differential conscious perceptual processing among tendency-based sub-groups.
