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

description: 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).
