Cake or broccoli? Recency biases children's verbal responses

Area of Science:

• Developmental Psychology
• Child Language Acquisition
• Cognitive Science

Background:

• Understanding prelinguistic and early-speaking children's thoughts is challenging.
• Limited-choice tasks are common for assessing child preferences and understanding.
• Adults exhibit order biases (e.g., primacy bias) in response tasks.

Purpose of the Study:

• To investigate whether young children exhibit response biases when presented with choices.
• To determine the nature and characteristics of any observed biases in toddlers.
• To compare children's response biases with those typically seen in adults.

Main Methods:

• Experiments involving toddlers presented with "or" questions in a lab setting.
• Analysis of a naturalistic corpus of caretaker-child speech interactions.
• Examination of how age and choice syllable-length influence response bias.

Main Results:

• Toddlers consistently demonstrated a verbal recency bias, favoring the last option presented.
• This recency bias was observed in both controlled lab tasks and naturalistic speech.
• The recency bias diminished with increasing age and strengthened with longer choice phrases.

Conclusions:

• Children exhibit a distinct recency bias, differing from the primacy bias seen in adults.
• The findings suggest that working memory limitations may underlie this recency bias in children.
• This research offers insights into the cognitive underpinnings of early language development and decision-making.
