Facility in Name Retrieval and Alphabetic Mapping as Co-determinants of Skill or Lack of Skill in Word Identification.
Vellutino, Frank R.; Scanlon, Donna M.
A study examined (1) the relative contributions of skill in name retrieval and alphabetic mapping to the acquisition of skill in word identification, (2) the differential aspects of deficiencies in each of these processes on word identification, and (3) the differential effects of name familiarization and training in phonemic segmentation and alphabetic mapping on word identification. Subjects--age/grade matched and reading ability matched groups of poor and normal readers in grades two and six--were given tests of phonemic segmentation and alphabetic mapping ability and then randomly assigned to one of five different treatment conditions: (1) a name familiarization condition; (2) a phoneme segmentation/alphabetic mapping condition; (3) an "eclectic" condition with both types of instruction; (4) a control condition with both the learning and transfer tasks; and (5) a control condition with only a transfer task. All subjects were then administered an alternate form of a phoneme segmentation test used as the pretest. Findings showed that the poor readers performed significantly below the normal readers on both the pretest and the posttest of phonemic segmentation ability. Findings also showed that poor readers at both grade levels performed significantly below the normal readers on the free recall subtest of response acquisition and on the picture-syllable subtest of response acquisition. Results indicated that both name retrieval and alphabetic mapping are important determinants of skill in word identification and that deficiencies in either skill will cause reading disability. Findings suggest that dysfunction in phonological coding may be a common factor underlying deficiency in both name retrieval and alphabetic mapping. (Tables of data and figures are appended.) (NKA)
