Memory strength and recency judgments.

Area of Science:

• Cognitive Psychology
• Human Memory

Background:

• Numerical judgment of recency (JOR) is influenced by memory characteristics.
• The relationship between memory strength and perceived recency requires further investigation.

Purpose of the Study:

• To investigate the effect of memory strength on numerical judgment of recency (JOR).
• To contrast the activation hypothesis (stronger memories seem more recent) with the accuracy hypothesis (JOR is more accurate for stronger memories).

Main Methods:

• Two experiments were conducted manipulating memory strength.
• Stimulus type (pictures vs. names) and study duration (long vs. short) were used to define memory strength.
• Participants performed numerical judgment of recency tasks.

Main Results:

• Both experiments provided support for the activation hypothesis.
• Stronger memory items were judged as more recent compared to weaker items.
• No support was found for the accuracy hypothesis.

Conclusions:

• Memory strength significantly influences the perception of recency.
• Recency judgments are partly inferred from memory activation and partly from other time-related cues.
• Findings contribute to understanding the mechanisms underlying temporal memory retrieval.
