Offloading information to an external store increases false recall.

Area of Science:

• Cognitive Psychology
• Human Memory
• Memory Strategies

Background:

• Offloading information to external memory stores is a common strategy.
• However, reliance on external memory can impair internal memory recall.
• The impact of offloading on both accurate (true) and inaccurate (false) recall is not fully understood.

Purpose of the Study:

• To investigate how offloading information affects true and false recall.
• To examine the differential impact of offloading on memory encoding.

Main Methods:

• Three experiments were conducted involving participants studying word lists.
• Participants wrote down word lists, with recall performance compared between offloading and no-offloading conditions.
• In the offloading condition, participants knew they would access their written lists during recall.

Main Results:

• Offloading information significantly decreased true recall of presented words.
• Conversely, offloading increased false recall of unstudied critical words associated with the lists.
• These findings suggest a trade-off in memory recall accuracy.

Conclusions:

• Offloading memory to external sources impairs accurate recall of learned material.
• This strategy enhances susceptibility to false memories for related but unpresented information.
• Results indicate offloading differentially affects the encoding of gist-based versus verbatim memory traces.
