A demonstration and comparison of two types of inference-based memory errors.

Area of Science:

• Cognitive Psychology
• Human Memory
• Schema Theory

Background:

• Everyday routines are often encoded and recalled based on pre-existing knowledge structures, or schemas.
• Schemas can influence memory accuracy, potentially leading to both enhanced recall and inferential errors.

Purpose of the Study:

• To investigate how schema relevance affects recognition memory confidence.
• To examine inferential memory errors, specifically the backward inference effect, where an effect leads to false recognition of a cause.
• To differentiate the underlying mechanisms of different types of inferential memory errors.

Main Methods:

• Participants viewed slides of ordinary routines and were tested on recognition.
• Experiment 2 involved presenting cause or effect scenes and testing recognition memory over time.
• Experiment 3 distinguished between false recollection and familiarity in inferential errors.

Main Results:

• Higher recognition confidence was observed for schema-relevant items compared to schema-irrelevant items.
• Participants falsely recognized new cause scenes as previously viewed when presented with the effect scene.
• Inferential errors, including false alarms to cause scenes and schema-high items, increased with longer retention intervals.
• The backward inference effect was associated with false explicit recollection, while false alarms to schema-high foils were based on familiarity.

Conclusions:

• Schema relevance impacts memory confidence and recognition accuracy.
• The backward inference effect is a distinct type of memory error.
• Different inferential memory errors may arise from distinct cognitive processes, namely recollection and familiarity.
