Adolescents' Developing Sensitivity to Orthographic and Semantic Cues During Visual Search for Words

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Educational Psychology

Background:

• Adolescent word recognition and visual search skills develop significantly during school years.
• Understanding how orthographic and semantic distractors affect visual word search is crucial for educational interventions.

Purpose of the Study:

• To investigate how orthographic and semantic distractors influence visual word search in adolescents aged 11-15.
• To examine the relationship between visual search efficiency, word identification skills, and age.
• To compare visual search performance in literal versus categorical search tasks.

Main Methods:

• Two eye-tracking experiments were conducted with adolescents (11, 13, 15 years old).
• Experiment 1 involved a literal search task (target word provided).
• Experiment 2 used a categorical task (target defined by category).
• Search times, gaze patterns, and word identification skills were measured.

Main Results:

• Visual search efficiency improved with age, characterized by reduced gaze at non-target words and faster rejection of distractors.
• Enhanced word identification skills strongly correlated with search efficiency, particularly in the categorical task.
• Both orthographic and semantic distractors increased search times across all age groups in the literal task.
• Semantic distractors had a greater impact in the categorical task, requiring longer fixations before rejection.

Conclusions:

• Progressive automation of word decoding and improved lexical representations enhance visual search flexibility in older adolescents.
• Older adolescents demonstrate superior ability to guide visual search using perceptual and semantic word features, even without direct fixation.
• Difficulties in real-life information search, like web searching, may stem from underdeveloped lexical representations and word decoding skills in younger adolescents.
