The study found that, compared to normally achieving students, 24 students (age 10 and 12) with learning disabilities were less able in vocabulary production tasks and comparable in ability to use pictorial responses to demonstrate vocabulary knowledge. When equated in reading achievement, learning-disabled 10 year olds were poorer in composite…

The study demonstrated that 36 male children (ages 7-10) with learning problems were characterized not by a restricted vocabulary as such (i.e., the variance common to both receptive and productive vocabulary measures) but by a hampered production of words (i.e., the variance common to both speed-of-naming and productive vocabulary measures.…
