Q

Give an example of an experimental hypothesis in cognitive psychology.

A

There will be a significant increase in the number of words recalled from a list of 10 when rehearsal is allowed for 60 secs compared to when it is inhibited by a task of counting backwards in 3s for 60 secs.

Q

Give an example of a null hypothesis in cognitive psychology.

A

There will be no significant difference in the number of words recalled from a list of 10 when rehearsal is allowed for 60 secs compared to when it is inhibited by a task of counting backwards in 3s for 60 secs.
Any difference will be due to chance.
