The moving window technique: a window into developmental changes in attention during facial emotion recognition

Area of Science:

• Developmental psychology
• Cognitive neuroscience
• Visual perception

Background:

• Facial emotion recognition is crucial for social interaction.
• Developmental changes in visual attention strategies influence emotion recognition.
• Previous research indicates a left-visual field advantage in face perception.

Purpose of the Study:

• To investigate developmental changes in visual attention strategies during facial emotion recognition.
• To determine the age at which specific attentional biases emerge in children.
• To explore the relationship between attention to facial features and age.

Main Methods:

• Utilized the Moving Window Technique (MWT) with 129 participants (children aged 5-12 years and adults).
• Participants explored faces using a mouse-controlled window in an emotion recognition task.
• Analyzed attentional patterns to different facial regions across age groups.

Main Results:

• An age-related increase in attention to the left eye was observed starting at 11-12 years.
• This left-eye bias became statistically significant in adulthood.
• Findings align with previous eye-tracking studies and left-visual field biases.

Conclusions:

• A strategic attentional bias towards the left eye begins to develop around ages 11-12 years.
• This bias appears to be established during adolescence.
• Developmental shifts in visual attention strategies impact facial emotion recognition.
