Learning multiple rules simultaneously: Affixes are more salient than reduplications.

Area of Science:

• Cognitive Science
• Linguistics
• Psychology

Background:

• Language learners must identify and acquire linguistic regularities.
• Previous models suggest rule acquisition is based on Bayesian inference.
• An alternative view posits learning is guided by perceptual and memory salience.

Purpose of the Study:

• To investigate the factors influencing the learning of linguistic regularities.
• To contrast a salience-based learning account with Bayesian models.
• To determine if perceptual salience predicts cross-linguistic frequency of linguistic features.

Main Methods:

• Adult participants learned syllable strings with either affixation or reduplication patterns.
• Experimental stimuli manipulated the position (onset vs. offset) of these regularities.
• Performance was assessed to determine learning of both types of regularities.

Main Results:

• Participants successfully learned both affixation and reduplication regularities simultaneously.
• Affixation regularities were learned more readily than reduplication regularities.
• Regularities at sequence offsets were easier to learn than those at sequence onsets.

Conclusions:

• Findings support a perceptual/memory salience model over Bayesian criteria for rule acquisition.
• The observed pattern of learning difficulty aligns with the cross-linguistic frequency of linguistic features.
• Ease of acquisition may be a key factor driving the prevalence of certain linguistic regularities across languages.
