# Tables Below are presented the detail of the variables contained in each tables. . *Removed data due to problems at recall session : - S33-CBS : stimuli from the encoding day 1 - S05-SBC : O8 (odour)* ---------- ## all_recall_session This table mainly concerns the memory results and response time obtained during the recall session (4th day). Some encoding information from the encoding sessions are also given. #### **Memory variables** + **Recognition**: `recognition_response`: the subject response (1: I recognize ; 2: I don't recognize) `already presented` : determines if a stimulus was a target or a foil, here 1 means target and 0 means foil These variables were used to determine 4 types of response according to the signal detection theory (variable `score_recognition`): | score recognition | recognition response | already presented | meaning | | ------ | ------- |------- |------- | | **hit** | 1 | 1 |Recognition of a target| | **miss**| 0 | 1 |Non recognition of a target| | **fa** | 1 | 0 |Recognition of a foil | | **cr** | 0 | 0 |Non recognition of a foil| + **Episodic Memory**: `episodic_score` is defined according to the subject recognition response and ability to go into the correct room and click on the correct box. 3 types of response are possible: | | | |------- |------- | | **Mem** | target cue only recognized (no other association) | | **Mem+**| recognition + context recollection | | **Mem++** | recognition + context and place recollection| + **Subjective recollection** The answer to the question asking whether subjects were feeling they could remember the entire associated episode or not. `responses_recollection`: 1 (Yes, I remember) or 0 (No, I don't) #### **Variables related to the response time** All times are relatives to the beginning of a trial. + `stim_time`: When the stimulus (music and face) is sent + `odor_time`: when the odor is sent (sent during the expiration following the stim_time) + `inspiration_time`: time of the inspiration following odor time + `recognition_time` + `response_recollection_time`: time at which the participant answer to the subjective recollection question. + `choosen_box_click_time`: time at which the participant give its last episodic response. *Note: in the main analysis, data point higher than the 9th decile had been removed. Some outliers have also been a priori identified, notably when a subject gives a recognition response before the stimulus is sent.* #### **Other variables** + `stimulus_name`: the name of each stimulus + `subject`: subject identifier + `Sensory modality`: odor, music, face + `nb_presentation`: Number of times a stimulus had been explored by a participant (5 times = minimum) + `encoding_day`: Day of encoding (1, 2, or 3) + `version`: the version of the experiment (V1 or V2) ---------- ## all_evaluation_session This table concerns the sensory evaluation of the stimuli (both target and distractors) done by the participants. The evaluation session was done on the 4th day of the experiment, just after the recall session. The stimuli were evaluated using 15cm-non-graduated bounded linear scales. They were measured with a millimetre precision, and were a posteriori transformed into scores from 0 to 10. The following variables are displayed: + `version`: the version of the experiment (V1 or V2) + `subject`: subject identifier + `stimulus_name`: the name of each stimulus + `Sensory modality`: odor, music, face For the following variables, the scaled boundaries are given: + `Pleasantness`: unpleasant – neutral – pleasant + `emotional_Intensity`: very weak – very intense + `familiarity`: unknown – very familiar + `complexity`: very simple – very complex ---------- ## all_questions_session This table concerns some global questions related to the participants. This session was done on the 4th day of the experiment, just after the evaluation session. + `subject` + `version` + `gender` + `age` The following questions were evaluated using 15cm-non-graduated bounded linear scales, measured with a millimetre precision, and were a posteriori transformed into scores from 0 to 10. + `study_difficulty`: The global difficulty of the study + `task_awareness`: If they were aware that their memory will be investigated + `strategy`: Did they used any exploration strategy during encoding + `rethinking`: Whether they though about the experiment outside the laboratory + `odour_daily`, `music_daily`, and `face_daily`: How much they paid attention to odour/music/face in their everyday life + `music_training`: Number of years of formal musical training + `enc_association`: How hard did they try to associate the stimuli with each other during the opening of a box, at encoding For the following questions subjects were asked to rank (from 1 to 3) the three types of memory cues : + `odour_encod`, `music_encod`, and `face_encod`: ranking according to the attention they paid to these stimuli during the encoding phase + `odour_easyrecall`, `music_easyrecall`, and `face_easyrecall`: ease in remembering the room and the box when these stimuli were presented during retrieval phase ---------- ## respiration_recognition and respiration_episodic These tables concerns the breathing parameters recorded during either the time between cue presentation (or the first inspiration after an odour presentation) and: 1) the “Yes/No” recognition response: recognition period - respiration_recognition table; 2) the click on the box for the episodic retrieval: episodic period - respiration_episodic table. + `version`: the version of the experiment (V1 or V2) + `subject`: subject identifier + `stimulus_name`: the name of each stimulus + `Sensory modality`: odor, music, face #### **Memory variables** They are function of the investigated period: - The recognition period include recognition, subjective recollection and episodic responses; - the episodic period only include episodic *See description for the "all_recall_session" table for further details* #### **Respiration variables** + `nb_cycle`: The number of respiratory cycles (inspiration + expiration) that were included. + `is_during_inspi`: whether the stimulus has been send during the inspiratory phase or not (2 modalities: expi, inspi) at recall + `mean_cycle_duration`: the mean duration of a cycle + `mean_insp_amplitude`, `mean_exp_amplitude`: the mean amplitude of inspiration/ expiration + `mean_insp_volume`, `mean_exp_volume`: the mean volume of inspiration/ expiration
