Colour correspondence effects between controlled objects and targets.

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Motor Control

Background:

• Movement trajectories are increasingly used to infer mental processes during task performance.
• Cursor-to-target interactions are common in computer-based tasks, but cursor features are often overlooked.
• The influence of visual features, like color, between cursors and targets on task performance is not well understood.

Purpose of the Study:

• To investigate the impact of color relationships between cursors and targets on movement trajectories and reaction times.
• To determine if task relevance of color influences these effects.
• To explore the role of attention in color correspondence effects.

Main Methods:

• Five experiments were conducted using a mouse-controlled cursor and colored targets.
• Participants moved the cursor to targets, with varying task relevance assigned to cursor and target colors.
• Measures included response initiation latency, movement duration, and trajectory analysis.

Main Results:

• Color correspondence effects were observed in response latency, movement time, and trajectories when cursor and target colors were task relevant or only cursor color was relevant.
• These effects persisted even when color was task irrelevant, provided attention was directed to the cursor color.
• Response initiation effects were uncorrelated with movement time and trajectory effects when color relations were irrelevant.

Conclusions:

• Color correspondence between cursors and targets influences cognitive and motor processes in task performance.
• The findings suggest response coding and attention cueing play roles in these effects.
• Future research on movement trajectories in choice reaction tasks should incorporate cursor features.
