Learning difficult non-adjacent dependencies in language is possible. Prior experience with easier structures primes the brain to detect new, complex linguistic patterns, aiding acquisition.
Area of Science:
- Psycholinguistics
- Cognitive Science
- Language Acquisition
Background:
- Non-adjacent dependencies are common in human language but challenging to learn in laboratory settings.
- Existing research indicates that structural support, like high variability, aids learning of these dependencies.
Purpose of the Study:
- To investigate how typically difficult non-adjacent dependencies are learned.
- To test the hypothesis that prior learning of simpler dependencies facilitates the acquisition of more complex ones.
Main Methods:
- Three experiments were conducted using artificial language learning paradigms.
- Participants were exposed to learnable non-adjacent dependencies before encountering novel, difficult ones.
Main Results:
- Prior exposure to learnable non-adjacent dependencies significantly improved the learning of novel, typically undetected non-adjacent regularities.
- This suggests a scaffolding effect where initial learning supports subsequent complex structure discovery.
Conclusions:
- The discovery of complex linguistic structures can be cumulative, building upon learning experiences in supportive contexts.
- This highlights a mechanism for acquiring challenging grammatical patterns that are not immediately obvious.

Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
