Knowledge over Time of Action Codes for Perceived Objects: An Exploratory Study on Developmental Children.

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• Growing interest in processing tool objects and spatial stimulus-response (S-R) correspondence effects.
• Proposed accounts include affordance activation, location coding, and action coding.
• Action coding suggests perceived object direction influences motor performance.

Purpose of the Study:

• Investigate the action coding account of S-R correspondence effects in children.
• Compare reaction time (RT) performance between younger and older children.
• Hypothesize a larger correspondence effect in older children due to increased knowledge.

Main Methods:

• Compared RT performance in two age groups: younger (6-9 years) and older (10-13 years) children.
• Assessed S-R correspondence effects related to tool object perception.
• Analyzed differences in correspondence effects between age groups.

Main Results:

• Older children exhibited a 34 ms correspondence effect.
• Younger children showed an 18 ms correspondence effect.
• A larger correspondence effect was observed in older children compared to younger children.

Conclusions:

• Results support the action coding account for tool objects.
• Action direction is a key feature of tool objects, refined by experience and age.
• Increasing age and knowledge correlate with stronger action coding effects.
