    Experiment Instructions

    Thank you for taking part in this research. Please read and follow ALL instructions carefully.

    During this experiment you will be presented with 5 sessions.

    Each session will consist of 50 word pairs.

    Sessions will begin automatically after 15 seconds of viewing the instructions, and a 30 second countdown screen.

    <i>Your task will be to identify if the pairs of words are rhyming or not rhyming.</i>

    <b>For not rhyming pairs (e.g. Phone - Lamp) press the 'Z' key.</b>

    <b>For rhyming pairs (e.g. Mind - Behind) press the 'M' key.</b>

    There will be a practice session followed by 4 further sessions.

    During later sessions you will also be asked to respond to various additional events.


    Press any key to continue.

    # The number of pairs per list is equal to half of the number of pairs in the
