Abstract

Background and Aim: Fluent aphasia and Alzheimer patients have difficulties in perception and naming. Patient with fluent Aphasia and Alzheimer disease, both have difficulty in perception and naming. Their site of lesion is also identical, that is temporoparietal lobe which is damaged in both group. This study investigates the effects of semantic and phonological cues in facilitation of word finding.
Materials and Methods: The study was prescriptive - analytic cross-sectional with 14 patients. The participants were seven fluent aphasia with mean age 48.4 year old and seven Alzheimer patients with mean age 69/71 year old and mean Mini-Mental State Examination (MMSE) 16 score. Those were assessed with Persian Naming Test. The Aphasic patients were selected from Tehran University hospitals and Alzheimer ones were from Rouzbeh hospital and Alzheimer Association of Iran.
Results: Mean semantic and phonological cues in fluent aphasia patients were 2.71 and 12.29, respectively, which significantly different (p=0.01), but those results were 8.29 and 3.43 in Alzheimer patients, that were not significantly different (p>0.05). A main result of this study was significant difference between two cues in both groups.
Conclusion: Two groups of patients use two cues in word finding. The correct responses increase with phonological cue in fluent aphasia but semantic cue has the main role for naming in Alzheimer patients.

Abstract

Background and Aim: Reading is one of the human's communicative skills. Phonological awareness and rapid automatized naming are parts of the person's linguistic knowledge. Research in different languages and communities suggest that there is a relation between phonological awareness, rapid automatized naming and reading. To survey these relations in Persian language is the aim of this study.

Methods: In this study 130 male students from the first grade were selected at random. They were normal in IQ, visual and hearing status. Language development was also normal in these children. This study was a cross-sectional one. Pearson correlation coefficient and linear regression test were used to analyze data.

Results: The relation between phonological awareness and automatized rapid naming was significant (p<0.0001). Pearson correlation coefficient between phonological awareness and reading was direct (0.86). Pearson correlation coefficient between rapid automatized naming and reading was indirect that equals -0.87. In investigating the relation of two variables simultaneously with reading we concluded that the relation between phonological awareness, rapid automatized naming and reading is statistically significant (p<0.0001).

Conclusion: The results of this research revealed that in Persian language like other languages there is a relation between phonological awareness, rapid automatized naming, and reading. Reading skills of children could be improved with this exercises.

Abstract

Background and Aim: One of the common problems in many types of aphasia syndromes is word retrieval and/or production difficulty. So, designing a valid test that can examine this problem based on related processes and influencing factors is important. Picture confrontation naming is a typical method for assessing and treatment of word retrieval impairments. The aim of this study was determining the validity and reliability of oral picture-naming test in assessing word retrieval ability of aphasic adults.
Methods: Content and face validity of the test, that contains the line drawings of 115 Persian nouns, were assessed by speech therapists, graphists and painters. Then, the test was administered on 10 aphasics and 30 age-, gender- and education-matched normal subjects in two steps. Construct validity and internal consistency of test were investigated. External consistency was analyzed by test-retest method.
Results: The content and face validity of all items were more than 90 and 85 percents, respectively. There was a statistically significant difference between the mean scores of patients and normal subjects (p<0.001). The internal consistency of 0.98 was determined for the test. The intra-class correlation coefficient of this test was 0.98.
Conclusions: The oral picture-naming test had good content, face and construct validity. Also, internal and external consistencies were high. So, this test is a valid instrument for assessing naming ability of aphasic patients by a variety and big set of picture.

Abstract

Background and Aim: Phonological processing skills include the abilities to restore, retrieve and use memorized phonological codes. The purpose of this research is to compare and evaluate phonological processing skills in 6-7 year old blind and sighted Persian speakers in Tehran, Iran.
Methods: This research is an analysis-comparison study. The subjects were 24 blind and 24 sighted children. The evaluation test of reading and writing disorders in primary school students, linguistic and cognitive abilities test, and the naming subtest of the aphasia evaluation test were used as research tools.
Results: Sighted children were found to perform better on phoneme recognition of nonwords and flower naming subtests and the difference was significant (p<0.001). Blind children performed better in words and sentence memory the difference was significant (p<0.001). There were no significant differences in other subtests.
Conclusion: Blind children&aposs better performance in memory tasks is due to the fact that they have powerful auditory memory.

Abstract

Background and Aim: Rapid automized naming test is an appropriate tool to diagnose learning disability even before teaching reading. This study aimed to detect the cut-off point of this test for good readers and dyslexics.

Methods: The test has 4 parts including: objects, colors, numbers and letters. 5 items are repeated on cards randomly for 10 times. Children were asked to name items rapidly. We studied 18 dyslexic students and 18 age-matched good readers between 7 and 8 years of age at second and third grades of elementary school they were recruited by non-randomize sampling into 2 groups: children with developmental dyslexia from learning disabilities centers with mean age of 100 months, and normal children with mean age of 107 months from general schools in Tehran. Good readers selected from the same class of dyslexics.

Results: The area under the receiver operating characteristic curve was 0.849 for letter naming, 0.892 for color naming, 0.971 for number naming, 0.887 for picture naming, and 0.965 totally. The overall sensitivity and specificity was 1 and was 0.79, respectively. The highest sensitivity and specificity were related to number naming (1 and 0.90, respectively).

Conclusion: Findings showed that the rapid automized naming test could diagnose good readers from dyslexics appropriately.

Abstract

Background and Aim: Several studies have demonstrated deficits in rapid naming in dyslexic readers however the extent of deficit is different in various orthographies. This study was intended to survey the naming speed in Persian children with dyslexia.

Methods: Rapid automatized naming (RAN) task of 19 children with dyslexia were compared with 31 nondyslexic children. Participants were selected from the students of the second grade of primary schools in Tehran city, Iran, with normal intelligence [intelligence quotient]. Nondyslexic children were at the age of 7.7 to 8.7 years (mean=7.6) and dyslexics were 7.8 to 9.4 years old (mean=8.1). Reading accuracy and speed were assessed by text reading (Diagnostic Reading Test), and high frequency word, low frequency word and nonword reading (Reading and Dyslexia Test).

Results: Dyslexic readers needed more time than non-dyslexics when naming objects (p<0.001), numbers (p=0.001) and letters (p<0.001). The mean of dyslexics z-scores were -1.98 on objects, -1.96 on numbers and -3.35 on letters. 42% of dyslexics did not show any deficit on rapid automatized naming task. All of the subtests were correlated to reading speed (p<0.050), but among subtests of rapid automatized naming task, only letter naming was correlated to reading accuracy (p<0.050).

Conclusion: More than half of dyslexics cases showed an apparent deficit in naming speed (objects, numbers and letters), which was more evident at letters. Naming speed was related to reading accuracy and reading speed although the relationship was stronger with the second one.
