Data saving is not built in

This task collects experimental data but does not save it automatically. If you deploy this task for your study, you must implement your own data persistence mechanism (e.g., server-side logging, database, or file export).

Description

A two-session picture-naming experiment using short videos of imaginary creatures, each with a distinctive emotion, colour, movement, and sound. Participants are first taught 10 'learned' creature names (e.g. 'bamelu', 'carrudo') and are then asked to name them aloud when they reappear, mixed pseudo-randomly with 20 unlearned items used to test the production of semantically related unknown characters. Two warm-up examples (chien, chat) precede the main blocks. A microphone records each verbal response for offline analysis. Session 1 runs in the lab on PsychoPy and shows only the creature video. Session 2 has the same trial structure but additionally shows a verbal description of each creature before its video; session 2 supports both lab (PsychoPy) and online (PsychoJS / Pavlovia) execution.

Task Outputs

What it measures

Naming latency and lexical access for newly-learned vs. unlearned imaginary-creature names; spoken-response audio for offline acoustic and phonetic analysis.

Output formats

csv

PsychoPy / PsychoJS trial-by-trial CSV: condition (is_learned), stimulus filename (movie_file), description (session 2 only), microphone clip filename (mic.clip), and routine timing columns.

audio

One audio recording per trial captured from the microphone; the filename is referenced by mic.clip in the trial CSV. (Online preview cannot upload these clips — full audio export is only available in the lab PsychoPy run or via Pavlovia.)

Experimental design

Trial-based

30 trials

Within-subject: is_learned, session

Conditions

is_learned

learned

unlearned

— Whether the creature shown in the trial belongs to the 10 names taught at the start (learned) or to the 20 unlearned items used to probe production of semantically related unknown characters.

session

session_1

session_2

— Session 1: name the creature when its video plays. Session 2: a verbal description of the creature is shown before the video, and the participant names it after.

Key measures for analysis

Naming accuracy (offline scoring of audio recordings)
Naming latency (speech onset relative to stimulus onset)
Acoustic features of produced creature names

Recorded variables

Variable	Role	Type	Description	Unit
`movie_file`	independent	string	Relative path to the creature video shown on this trial (e.g. resources/learned/bamelu.mp4).	-
`is_learned`	independent	boolean	1 if the creature was in the learned set; 0 if it is an unlearned test item. Values: true, false	-
`description`	independent	string	Verbal description of the creature shown before its video (session 2 only).	-
`mic.clip`	dependent	string	Filename of the per-trial audio clip captured by the microphone — the participant's spoken naming response.	-
`learned_item.started`	metadata	number	Timestamp at which the learned/mixed-trial routine began (PsychoJS global clock).	s
`learned_item.stopped`	metadata	number	Timestamp at which the learned/mixed-trial routine ended.	s
