Effects of divided attention at encoding and retrieval: Further data

Area of Science:

• Cognitive Psychology
• Neuroscience
• Experimental Psychology

Background:

• Division of attention (DA) during learning significantly impairs memory.
• DA during retrieval has a less pronounced negative impact on memory recall.
• Previous research suggests DA's effect on retrieval is minimal, but its resource demands are acknowledged.

Purpose of the Study:

• To confirm the minor impact of DA on retrieval processes.
• To investigate the resource demands of retrieval operations.
• To explore the relationship between DA, levels-of-processing (LOP), and recognition memory.

Main Methods:

• Experiment 1: Assessed DA effects on retrieval accuracy and resource consumption, examining LOP effects.
• Experiment 2: Investigated the trade-off between recognition accuracy and latency under DA conditions, comparing with a concurrent reaction time task.
• Utilized continuous reaction time (CRT) tasks to measure processing trade-offs.

Main Results:

• DA at retrieval has minimal impact on accuracy, irrespective of encoding depth (LOP).
• Retrieval processes consume cognitive resources, but DA does not interact with LOP.
• A lawful trade-off exists between recognition decision latency and concurrent task performance, maintaining accuracy.

Conclusions:

• The limited effect of DA on recognition accuracy is an internal trade-off within the recognition task.
• Accuracy is preserved by a compensatory increase in decision latency when attention is divided during retrieval.
• DA does not affect recognition accuracy through task interference or familiarity judgments.
