In this study, you will rate phrases on how symmetrical they are in meaning. The phrases will appear one at a time, in the box below.

If a word or phrase is symmetrical it means that the meaning is "mutual". For example, 'cousin' is symmetrical because if someone is your cousin, you are also their cousin.

In contrast, 'father' is not symmetrical: If you are someone's father, they cannot be your father.

Another example of a phrase that is symmetrical is 'next to'. 'Next to' is symmetrical because if someone is next to you, you are also next to them.

In contrast, 'on top of' is not symmetrical: If you are on top of something, it cannot be on top of you.

Over the course of this survey, you will be rating different kinds of phrases. A few will be nouns like 'cousin' or 'father'. Some may be prepositions like 'next to' or 'on top of'. Others will be verbs like 'to slap' or 'to think'.

For all of these, you'll just be judging how symmetrical they are: the degree to which the meaning of the phrase is in some way "mutual".

There is no correct or incorrect answer. Go with your gut!

The whole study will only take about 7 minutes; please stay focused!
