Summary
Emotional feedback significantly impacts decision-making speed in the right hemisphere. Positive feedback speeds up responses, while negative feedback slows them down, influencing sensory-response translation.
Area of Science:
- Cognitive Neuroscience
- Neuroscience
- Psychology
Background:
- Emotional states can influence cognitive functions.
- The right hemisphere plays a role in processing emotional information and response selection.
Purpose of the Study:
- To investigate how feedback-related emotional states affect perceptual and response processes.
- To determine the role of the right hemisphere in mediating these effects.
Main Methods:
- Participants performed a task involving visual targets presented in either the left or right visual field.
- Feedback signals (positive, neutral, negative) preceded target presentation.
- Response times (RTs) were measured for compatible and incompatible spatial responses.
Main Results:
- Negative feedback significantly delayed RTs for left visual field targets requiring a left-hand response.
- Positive feedback facilitated RTs under the same conditions.
- These feedback effects were absent when verbal cues indicated the correct response.
Conclusions:
- Feedback-related emotional states modulate sensory-response translation processes.
- These modulations are specifically linked to right hemisphere functions.
- The findings highlight the interplay between emotion and action control.
