The Effect of One's Emotional State on the Memory

This experiment requires an investigation to prove ones emotional

state has a large effect on ones memory. In this case someone's in a

happy emotional state will have a better memory than someone in a sad

or depressed emotional state.

significantly more words than those having had listened to sad

This experiment is a Laboratory experiment which is good as it

provides a standard procedure to be repeated in a well controlled

environment. Such a design of experiments means extraneous variables

are kept to a minimum and thus prevents those becoming confounding

variables. As the standard procedure is easily repeated it enabled

this experiment to be more reliable. Although problems with carrying

out this laboratory experiment are that such a design suffers from low

ecological validity as participants are removed from their natural

surroundings and thus may act differently. As well as this there may

have been problems with demand characteristics as participant may have

believed they had to get a really high or really low score on the

number of words remembered.
