Do goal cue and motor activity impact preschoolers' working memory?

Area of Science:

• Cognitive Development
• Developmental Psychology

Background:

• Preschoolers exhibit lower working memory (WM) performance compared to older children.
• This deficit has been attributed to goal neglect, impairing strategy use.
• Game-like tasks can improve WM by providing goal maintenance cues, but the specific effective features remain unclear.

Purpose of the Study:

• To investigate the distinct effects of potential goal cues (toys) and motor activity in game-like tasks on preschoolers' WM.
• To determine whether preschoolers' WM limitations stem fundamentally from goal neglect.

Main Methods:

• A study involving 5- to 7-year-old children examined WM performance.
• Children participated in game-like tasks where the toy served as a potential goal cue and motor activity was present.
• Performance was compared across conditions to isolate the impact of the toy versus the motor activity.

Main Results:

• No improvement in WM performance was observed when a toy acted as a potential goal cue.
• Motor activity within the game-like tasks consistently had a detrimental effect on WM performance across all age groups.
• This negative impact of motor activity may be due to attentional distraction from maintenance processes.

Conclusions:

• Preschoolers' poor working memory performance is not fundamentally caused by goal neglect.
• The motor component of game-like tasks can interfere with WM, potentially by diverting attention.
• Future interventions should consider minimizing distracting motor elements to support WM development.
