Week 8 reading

Overspecification and confederate priming

The plan for week 8

This week we are looking at Loy & Smith (2021), which is recent paper by my former postdoc Jia Loy and me. This paper reports a bunch of experiments (5 total in this version, although we have to add more in the revision) where participants interact with a partner on a picture-description task where they take turns describing pictures. Unbeknownst (usually) to the genuine participants, the person they are interacting with doesn’t actually exist - instead, what they hear from their partner is a sequence of pre-recorded audio designed by us. This method allows us to control the structure of the descriptions produced by one interlocutor and see how that affects the descriptions used by the other interlocutor, the genuine participant. The standard result in these paradigms is that participants are influenced to produce descriptions which match those of their partner. We were interested in whether this effect would be modulated by the efficiency of the partner descriptions - do people follow this tendency to copy the form of their partner’s descriptions even if the partner’s labelling behaviour is inefficient (i.e. includes adjectives which are unnecessary for the partner to select the correct picture)? As far as I remember we started running this series of experiments in Covid times, hence the switch from lab to online data collection.

As usual, in this week’s practical you’ll get a chance to look at a similar experiment in jsPsych, which will involve audio stimuli again but also the infrastructure to record audio from your participants via their browser.
