This online adaptation of the Intermodal Preferential Looking Task was developed to see if in-lab findings in very young children could be replicated using an online modality.
To see the full experimental procedure from start to finish, use the link below named: FULL EXPERIMENT_Intermodal Preferential Looking Paradigm (IPL) Experiment- Word Recognition in 2-year-olds.
All the individual components to this experiment are also listed below.
To replicate this study, you will need to gain access to the webcam recording feature in Gorilla since it is in Beta, so not a default option.
This study has since been developed into a semantic priming study and used on 30-month-olds, and 36-month-olds. Link coming soon.

This is the informed consent form for parents/carers to complete before beginning the experiment. It explains why the research is being done, what the experiment involves, how data will be handled, and how a parent/carer can opt out.

This is a demographic questionnaire which relates to the parent/carer who is doing the IPL study with the child. It covers questions such as the relationship to the child, education, and language use.

This is the landing page for when a parent/carer does not enter the correct information to make them eligible for the infant IPL word recognition task in 2-year-olds. For example, if they indicate their child is bilingual, this would make them ineligible to continue.

The procedure begins with instructions for a parent/carer to prepare their device, environment, and child for testing. There is an audio test task so the parent/carer can see what the webcam will record.
A calibration phase of 4 trials acts as a baseline measure to observe looking behaviour and ensure the child looks to the side of the screen that the image is first presented on.
A short attention-getting video of black and white objects and sounds begins the experimental phase. Two blocks of 12 trials are divided by the same video, which is also repeated at the very end of the 24 trials. Trials are not infant-initiated as they would be in the lab, but run automatically, without pause from start to finish.
For each trial, a smiley fixation point precedes 2 images which are displayed on the right and left side of the screen: one target image, and one distractor image. The 2 images are displayed for 2500ms (pre-naming phase) before an auditory stimulus labels the target image at 2500ms. The 2 images then remain on screen for a further 2500ms of free-looking time (post-naming phase).
Trials are recorded individually and require offline manual coding of eye position. We used a bespoke piece of software to divide each trial into 50ms stills and then coded gaze as: left, right, on-screen but an indeterminate location, or off-screen. For each trial, we then calculated the proportion of looking time to the target image as: looks to target/ looks to target + looks to the distractor. This was calculated for the pre-naming and the post-naming phases. The expectation is that a child will look longer at the picture which is labelled auditorily, indexing word recognition.

This is the complete experimental procedure that was used for the infant IPL word recognition study in 2-year-olds and includes the demographic questionnaires and debrief etc.

Built with Experiment
This version of the experiment can be used if the parent/carer does not need to complete the demographic questionnaires. For example, if they started the process but had a technical error at the point of starting the experiment. In this scenario, the data from the questionnaires will have been saved, and to avoid having the parent/carer do this part of the procedure again, this link will give them access to the experiment only.
