E - Baddeley and Hitch: Players were asked to recall the names of the teams they had played against earlier in the season. Players who had played the mostgamesforgot proportionately more games.
E - This suggests that retroactive interference has occurred.
L - Therefore, Baddeley and Hitch provide evidence of interference occurring in the real-word, increasing the ecological validity.
E - Much of the research comes from lab experiments. While lab experiments produce high internal validity, they involve artificialtasks.
E -There is a greaterchance of interference occurring in a labcompared to reallife situations due to the stimulusmaterialtypically being a list of words.
L - Therefore, this means that interference isn't applicable to forgetting in everyday life.
Interference is more likely to occur when the two pieces of information are similar due to response competition.
Time sensitivity
Interference is less likely to occur when there is a large gap between the instances of learning.
+ Evidence from labstudies
E - Interference is one of the mostconsistently demonstrated findings. Most of these studies show that PI and RI are common ways information can be forgotten from the LTM.
E - Lab experiments have control over variables.
L - Therefore, this suggests that the results have high validity. However, there is a weakness of lab studies.
