Materials

The selected pictures were further divided into eight subsets, which were combinations of four possible Conditions (labeled, matched, new for short-interval, new for long-interval) and two Picture Valence (negative, neutral). During the immediate exposure phases, four subsets were used as target pictures for either the labeling or matching condition in the label-and-match intervention. In the short-interval phase, these same four subsets were displayed again during the emotion rating. Additionally, two new subsets (neutral and negative) for the short-interval were added as novelty stimuli to do the manipulation check. The long-interval reexposure phase followed the same structure: the original four subsets were presented again for a second round of reexposure, along with two new subsets (neutral and negative) as long-interval novelty stimuli. Across all phases and conditions, participants viewed the same image sets, with the presentation order randomized within each phase to maintain consistency.

•The folder titled ‘Open_Data_Affect_Labeling_Self-reports’ contains an Excel file named ‘stimuli_picture’, which provides comprehensive information about the images used in the study. This file includes each image’s filename, transformed normative ratings (1-9 Likert scale) for arousal and valence, and Picture Valence (negative, neutral, positive). Additionally, the file indicates how each image was pseudorandomly assigned to a specific Intervention Condition (labeled, matched, new for shorter-interval, new for long-interval).

DATA

Immediate exposure Phase

·       The folder ‘Open_Data_Affect_Labeling_Self-reports’ contains an Excel file named ‘immediate’, which includes raw data on arousal and valence ratings collected for each trial per participant, along with their response times during the rating task. The columns in the file are: subject, arousal, arousal_RT, valence, valence_RT, Condition_Picture Valence, and group. The Condition_Picture Valence column indicates both the Condition (labeled or matched) and Picture Valence (negative or neutral).

Short-Interval Reexposure Phases

·       The folder ‘Open_Data_Affect_Labeling_Self-reports’ contains an Excel file named ‘short-interval’, which includes raw data on arousal and valence ratings collected for each trial per participant, along with their response times during the rating task. The columns in the file are: subject, arousal, arousal_RT, valence, valence_RT, Condition_Picture Valence, and group. The Condition_Picture Valence column indicates both the Condition (labeled, matched, new) and Picture Valence (negative or neutral).

Long-Interval Reexposure Phases

·       The folder ‘Open_Data_Affect_Labeling_Self-reports’ contains an Excel file named ‘long-interval’, which includes raw data on arousal and valence ratings collected for each trial per participant, along with their response times during the rating task. The columns in the file are: Device_Type, Monitor_Size, subject, scale (arousal, valence), rating, RT, Condition_Picture Valence, and group. The Condition_Picture Valence column indicates both the Condition (labeled, matched, new) and Picture Valence (negative or neutral).
