Memory as a function of attention, level of processing, and automatization.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Memory Research

Background:

• Theories of memory formation distinguish between automatic and controlled processing.
• Automatic/controlled processing theory posits that controlled processing is essential for long-term memory (LTM) storage.

Purpose of the Study:

• To investigate the relationship between LTM modification, attentional allocation, and different types of cognitive processing.
• To test predictions of automatic/controlled processing theory and challenge the "automatic encoding" proposal.

Main Methods:

• Experiment 1 involved tasks such as intentional learning, semantic categorization, graphic categorization, and digit-search with and without word learning.
• Experiment 2 trained participants to develop automatic categorization skills.
• Frequency judgments and recognition memory were used as measures of LTM storage.

Main Results:

• Semantic and intentional learning conditions yielded more accurate frequency judgments than graphic categorization.
• Distracting digit-search tasks significantly impaired frequency judgment accuracy.
• Extensive training of automatic categorization resulted in minimal frequency learning and recognition.

Conclusions:

• Controlled processing, particularly semantic and intentional learning, is crucial for effective LTM storage.
• Automatic processing, even when highly practiced, does not lead to significant LTM encoding.
• Findings contradict the notion of "automatic encoding" for certain types of information processing.
