Phonological and morphological processing in adult students with learning/reading disabilities

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Neuroscience

Background:

• Learning and reading disabilities significantly impact academic performance.
• Information processing deficits, particularly in phonological and morphological tasks, are key areas of investigation.
• Understanding these challenges in college students is crucial for targeted interventions.

Purpose of the Study:

• To compare phonological and morphological processing in college students with learning/reading disabilities against control groups.
• To investigate the automaticity of lexical item processing in this population.
• To identify specific differences in processing morphological words and morphographic strings.

Main Methods:

• Computerized information-processing tasks were administered.
• Participants included college students with learning/reading disabilities, reading-age (RA) matched controls, and chronological-age (CA) matched controls.
• Tasks assessed accuracy and reaction time in phonological (pseudohomophone judgment, rhyme detection) and morphological processing.

Main Results:

• Target students showed slower reaction times and lower accuracy than CA controls on phonological tasks.
• No significant differences were found between target students and RA controls on these tasks.
• Target students exhibited distinct quantitative and qualitative differences in processing morphological information.

Conclusions:

• Accurate and rapid processing of lexical items is essential for automaticity in reading.
• Phonological processing deficits are evident in college students with learning/reading disabilities compared to CA peers.
• The integration of phonological and morphological knowledge is critical for supporting adult learners with reading difficulties.
