Acquisition of arbitrary conditional discriminations by young normally developing children

Area of Science:

• Developmental Psychology
• Behavioral Psychology

Background:

• Arbitrary conditional discriminations are complex cognitive tasks.
• Acquisition of these discriminations is crucial for higher-order learning in children.

Purpose of the Study:

• To investigate methods for facilitating the acquisition of arbitrary conditional discriminations in young children.
• To identify effective instructional and naming strategies for learning arbitrary stimulus relations.

Main Methods:

• Three experiments were conducted with normally developing children aged 3–6 years.
• Methods included differential reinforcement, instructions, sample naming (experimenter-provided and self-generated), and thematically related stimuli training.
• A match-to-sample task was used to assess acquisition.

Main Results:

• Differential reinforcement alone was insufficient for task mastery.
• Instructions and sample naming significantly improved acquisition.
• Experimenter-provided nonsense syllable names were more effective than self-generated names.
• Thematic stimulus training facilitated the transition to arbitrary relations.

Conclusions:

• Instruction and specific naming strategies are critical for teaching arbitrary conditional discriminations to young children.
• The type of naming (experimenter-provided vs. self-generated) impacts learning effectiveness.
• Further research is needed to understand the developmental trajectory of these complex stimulus relations.
