Age, rate and instructional conditions: empirical support against the pacing variable

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Human Learning

Background:

• The pacing effect, where faster presentation rates lead to better learning, has been observed in previous studies.
• Concerns exist that the pacing effect might be an artifact due to the confounding of presentation rate and total learning time.

Purpose of the Study:

• To investigate whether the observed pacing effect in learning is a true phenomenon or an artifact of experimental design.
• To differentiate the influence of presentation rate versus total learning time on paired-associate and free-recall tasks.

Main Methods:

• Factorially varied two presentation rates with three instructional conditions across two age groups.
• Employed paired-associate and free-recall learning tasks.
• Manipulated total learning time to be confounded with presentation rate in one condition and equated in another.

Main Results:

• The pacing effect was replicated when learning time was confounded with presentation rate.
• When total learning time was equated across presentation rates, the pacing effect was not observed.
• Instructional conditions yielded different performance levels between young and old age groups.

Conclusions:

• The pacing effect appears to be an artifact, not a genuine learning principle.
• The total time principle offers a more viable explanation for learning outcomes than pacing.
• Instructional effectiveness varies significantly between different age groups, challenging assumptions of universal applicability.
