Background information:

Sample details

Type of sample:
36 (20 female) participants between 18 and 33 years of age (M = 24.06).
Recruitment information:
Online advertisements and flyers. Since the specific recruitment led to a primary participant pool heavily skewed to younger ages with only very few potential participants beyond the age of 35 we introduced an age limit of 35 in order to prevent outliers in our analysis. The selection process was further guided to achieve an approximately uniform distribution of scores on the BFI-2 neuroticism scale.
Incentives:
---
Exclusions:
One participant had to be excluded from the analysis because of a critical life event between the fMRI part and the ESM part of the study and another participant had to be excluded because of registration problems during MRI preprocessing.
Number of participants:
36
