What is the effect of continuous trials on recall accuracy with the same type of stimuli?

The correct answer highlights that continuous trials with the same type of stimuli can lead to a decline in recall accuracy. This phenomenon can be attributed to several cognitive processes.

When participants are repeatedly exposed to the same stimuli during trials, a state known as "repetition suppression" may occur, where the brain becomes less responsive to the repeated information. This can lead to reduced attention or diminished processing resources for that specific stimulus, making it harder to retrieve the information accurately.

Additionally, the phenomenon of proactive interference can further contribute to declining accuracy. With continuous trials, older memories can interfere with the retrieval of new information, resulting in confusion and errors in recall.

Finally, cognitive fatigue may also play a role if the same type of stimuli is presented repeatedly. As cognitive resources become drained, attention and memory functions may become compromised, leading to further inaccuracies in recall.

In contrast, improvement in accuracy may be seen in scenarios involving varied stimuli, where differences can aid in memory differentiation and enhance recall.
