Luck and learning: feedback contingencies and initial success in verbal discrimination learning

Area of Science:

• Cognitive Psychology
• Learning Sciences

Background:

• Understanding factors influencing learning efficiency is crucial.
• Previous theories often assume linear relationships between initial performance and learning outcomes.

Purpose of the Study:

• To investigate the impact of feedback type and initial success on verbal discrimination learning.
• To examine the interaction between feedback and initial success in a learning task.

Main Methods:

• Ninety undergraduates learned a 12-pair verbal discrimination list.
• Independent variables included feedback (positive, negative, both) and initial success (17%, 50%, 83%).
• Total errors over nine trials served as the dependent variable.

Main Results:

• The main effect of feedback type on learning was not significant.
• Initial success significantly impacted learning; 83% initial success led to quickest learning, 50% to slowest.
• The interaction between feedback and initial success was not significant.

Conclusions:

• Initial success plays a significant role in learning efficiency, exhibiting a curvilinear relationship.
• Findings support the rule-use component of frequency theory.
• Learning performance is more complexly related to initial success than previously assumed.
