Peterson And Peterson

What was the topic regarding the study of Peterson and Peterson?

• Working Model Of Memory

• Multistore Model of Memory

• Synthetic Store of Memory

• Working Multistore Memory

What was the aim of Peterson and Peterson?

• Duration of short term memory when rehearsal is prevented

• Duration of short term memory when rehearsal is provided

• Capacity of long term memory

• Encoding of long term memory

How many participants took place in this study?

What type of experiment was it and what did they have to do?

• Covert opportunistic experiment and they were asked to spell a word

• Naturalistic experiments and they were asked to recall trigrams

• Quasi experiment where they were asked to recall what they ate for breakfast

• Lab experiment and they were asked to recall trigrams

How did they prevent rehearsal?

• The participants were asked to answer immediately

• The participants were asked to count forwards in threes or fours until they saw a red light appear

• The participants were asked to count backwards in threes or fours until they saw a red light appear

• The participants were screamed at until a red light appeared

What experimental design was used in this study?

• Repeated measures design

• Independent measures design

• Matched pairs design

• Blind pairs design

What were the results of the study?

• The longer the interval delay the more trigrams were recalled.  

• The longer the interval delay the less trigrams were recalled.  

• The shorter the interval delay the less trigrams were recalled.  

• If there was a longer interval, exactly 43% more trigrams were recalled

The duration of short term memory is __ seconds or less.

What does the study conclude?

• The multistore model of memory is inaccurate.

• Short-term memory has a limited duration when rehearsal is prevented.

• It supports the multistore model of memory

• Long term and short term memory are pretty much the same thing

One strength of the study was: Since it was a lab study, the control of the extraneous variables ensures ________ validity
