[Age and analytic-synthetic activity of school-children solving problems with an elementary pattern]

Area of Science:

• Cognitive development
• Developmental psychology
• Educational psychology

Background:

• Understanding how children learn and develop cognitive skills is crucial.
• Previous research indicates varying developmental trajectories for different cognitive abilities.

Purpose of the Study:

• To investigate the impact of age on task performance using different representational schemes.
• To explore the development of abstract-logical connections in schoolchildren.

Main Methods:

• Participants: Schoolchildren from 1st to 10th grades.
• Task: Solving a consistent elementary scheme with 14 possible actions.
• Conditions: Task presented via buttons/lamps versus symbolic representations.

Main Results:

• Performance on the button/lamp task did not improve with age; younger children were faster.
• Performance on the symbolic task improved with age.
• Initial slowness in the symbolic task decreased with age, with senior students performing equally on both task types.

Conclusions:

• Task representation significantly influences performance and developmental trends.
• The findings suggest the development of abstract-logical reasoning abilities with age.
• Ontogenetic formation of generalized abstract-logic connections underlies these performance differences.
