Empatica E4 dataset: young/older × autobiographical photos/IAPS/autobiographical locations

This package contains data recorded with the Empatica E4 wristband during an experiment with:(1) induction of negative emotion using a film clip, and(2) positive recovery using images.There are six folders corresponding to **age group** (young / older) × **image condition** (autobiographical photos, IAPS, autobiographical locations). IMPORTANT: In the two autobiographical conditions, the images are **associated with each participant’s specific positive autobiographical memories**—either their own personal photographs (high personal relevance) or photographs of **personally meaningful locations** (medium personal relevance). The IAPS condition uses positive IAPS images (low personal relevance). 1) Folder structure/├─ jovenes_fotos_personales/ (young — autobiographical photos)├─ jovenes_iaps/ (young — IAPS)├─ jovenes_localizaciones/ (young — autobiographical locations)├─ mayores_fotos_personales/ (older — autobiographical photos)├─ mayores_iaps/ (older — IAPS)└─ mayores_localizaciones/ (older — autobiographical locations) Inside each condition folder there is one subfolder per participant (anonymous code), e.g.:jovenes_fotos_personales/ └─ P0100/ ├─ P0100_1_acc_data.csv (accelerometer) ├─ P0100_1_bvp_data.csv (BVP) ├─ P0100_1_eda_data.csv (electrodermal activity) ├─ P0100_1_ibi_data.csv (inter-beat intervals) ├─ P0100_1_tmp_data.csv (skin temperature) └─ P0100_1_eve_data.csv (events/markers) 2) Files at the dataset root- README_E4_EN.txt (this file)- PROCEDURE_E4_EN.txt (protocol overview)- database_SPSS.sav (YOUR SPSS file with socio‑demographics and PANAS; optional)- (optional) LICENSE.txt 3) Minimum CSV format- *_acc_data.csv → columns: timestamp, acc_x, acc_y, acc_z (g)- *_bvp_data.csv → columns: timestamp, bvp (a.u.)- *_eda_data.csv → columns: timestamp, eda_microsiemens (µS)- *_ibi_data.csv → columns: timestamp, ibi_seconds (s; events)- *_tmp_data.csv → columns: timestamp, temp_c (°C)- *_eve_data.csv → columns: timestamp, label (e.g., baseline, clip, photos_pos) Timing: seconds relative to the **start of the experiment** or UNIX epoch. Use the same criterion for all participants.CSV separator: comma. Encoding: UTF‑8. 4) Privacy- No names, emails or other direct identifiers are included.- Participants are coded (e.g., P0100). Stimuli (film and personal photos) are **not shared**. 5) Short experiment description- Negative emotion induction: film clip (execution scene).- Positive recovery: **six images** depending on condition: • autobiographical photos (high personal relevance; **linked to specific positive autobiographical memories**) • autobiographical locations (medium relevance; **linked to specific positive autobiographical memories**) • positive IAPS images (low personal relevance).- PANAS at three times: before film (T1), after film (T2), after images (T3). 6) How to cite (replace with your DOI when published)Surname, N.
