Guessing versus misremembering in recognition: A comparison of continuous, two-high-threshold, and low-threshold...

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Memory

Background:

• Recognition memory models explain errors differently: two-high-threshold (2HT) suggests guessing, while continuous unequal-variance (UV) and low-threshold (LT) models propose retrieval of misleading information.
• Understanding the source of memory errors is crucial for refining cognitive models.

Purpose of the Study:

• To investigate the underlying mechanisms of memory errors in recognition tasks.
• To compare the predictive accuracy of the 2HT, UV, and LT models of recognition memory.

Main Methods:

• Two experiments were conducted where participants studied word lists and then performed a recognition test.
• Participants initially guessed if a word was studied, followed by a recognition response after viewing the word.
• Receiver Operating Characteristic (ROC) functions were analyzed using parametric bootstrap procedures to evaluate model fit.

Main Results:

• Participants made more errors when attempting to recall a word, even when probability cues suggested the correct response, indicating retrieval of misleading information.
• Model fitting analyses demonstrated that the UV and LT models provided a better fit to the data than the 2HT model.

Conclusions:

• Memory errors in recognition tasks primarily stem from retrieving misleading information rather than simple guessing.
• The findings provide empirical support for the UV and LT models, challenging the assumptions of the 2HT model in explaining recognition memory performance.
