Iconicity and sign vocabulary acquisition

This study was designed to investigate learning and retention of isolated sign vocabulary as a function of sign classification (iconic, opaque, or abstract). The subjects were 28 hearing college students naive to sign vocabulary. They were drilled with 30 signs from American Sign Language that had been classified as iconic, opaque, or abstract. Training was conducted using two different media: computer-assisted instruction and videotaped presentation. Performance scores for the three types of signs were significantly different. Scores were consistently higher for iconic signs, regardless of the training mode. The videotaped presentation mode produced the greatest consistency in scores. The results of this study support the notion that it is easier for beginning students of sign language to learn and retain iconic signs.     

Developmental milestones: sign language acquisition and motor development

The sign language and motor development of 11 young children of deaf parents were studied across a 16-month period. The subjects showed accelerated early language development producing, on the average, their first recognizable sign at 8.5 months, their tenth sign at 13.2 months, and their first sign combination at 17.0 months. In contrast, children learning to speak typically do not attain the equivalent spoken language milestones until 2-3 months later. The structure and content of the subjects' 50-sign vocabularies closely resembled those for children at the same stage in previously published studies of spoken language acquisition. The pattern of synchrony between motor and language development previously reported by investigators of children learning to speak was found not to apply to the population of the present study: most of the subjects learning to sign did not slow down in their rate of language acquisition after achieving a new motor milestone, but rather continued to show a gradual increase in the size of their sign language vocabularies.     

Keywords and vocabulary acquisition: Some words of caution about words of assistance

Consistent results of two experiments with relatively technical, native language vocabulary, showed that effectiveness of keyword methods depended upon whether meanings of words to be learned were abstract or concrete and whether comprehension was assessed immediately or after a delay. Keywords bearing acoustical similarities to vocabulary items whose meanings were presented as sentences consistently facilitated students’ retention of the meanings of concrete items on immediate posttests. However, in contrast to recent research on foreign language vocabulary having simpler definitions, these experiments showed that it may be difficult to use the keyword method to aid long-term retention with moderately complex. abstract, native language vocabulary. Parts of this study, which was partially supported by the Kansas State University Bureau of General Research, were presented at the Annual Meeting of the American Educational Research Association, Boston, 1980.     

Phonological working memory: A critical building block for reading development and vocabulary acquisition?

In this article we review findings from a recent longitudinal study of the contribution of phonological working memory to vocabulary acquisition and reading development. A total of 80 children were tested initially at school entry at the age of four years, and were tested in three further waves at ages 5, 6, and 8 years. The results indicate that phonological memory skills constrain vocabulary growth during the first year or so in school but that subsequently, vocabulary knowledge is a pacemaker in the development relationship with memory. Phonological memory skill in prereading children was found to be significantly linked with scores on a reading test at age 8 which encourages the use of a phonological recoding strategy. The theoretical and practical implications of the findings, and important areas for future research, are discussed.     

Infants with congenital deafness: on the importance of early sign language acquisition

Two boys who both had a profound bilateral hearing impairment met at a specialized sign preschool. Their preconditions were quite different, since in one of them the hearing impairment was detected in the maternity ward with the aid of otoacoustic emissions, and habilitation had begun at age 4 months. The other boy's impairment was not detected until age 2 years; habilitation was thus much delayed. Data were collected on the two boys using interviews with parents and teachers, observation, and video recording in the children's own environment at home and in the specialized sign preschool. Characteristic differences between the boys are described regarding their social and linguistic development relating to the time of detection of the hearing impairment. This illustrates the importance of early detection and habilitation so as to avoid separation of individuals into different groups with differing social and academic prospects, depending on the lack of early linguistic stimulation and consequent poor language acquisition. Giving children the possibility of developing a language is the primary consideration.     

Verbal and spatial analogical reasoning in deaf and hearing children: the role of grammar and vocabulary

The extent to which cognitive development and abilities are dependent on language remains controversial. In this study, the analogical reasoning skills of deaf and hard of hearing children are explored. Two groups of children (deaf and hard of hearing children with either cochlear implants or hearing aids and hearing children) completed tests of verbal and spatial analogical reasoning. Their vocabulary and grammar skills were also assessed to provide a measure of language attainment. Results indicated significant differences between the deaf and hard of hearing children (regardless of type of hearing device) and their hearing peers on vocabulary, grammar, and verbal reasoning tests. Regression analyses revealed that in the group of deaf and hard of hearing children, but not in the hearing group, the language measures were significant predictors of verbal analogical reasoning, when age and spatial analogical reasoning ability were controlled for. The implications of these findings are discussed.     

Differences in arithmetic subtraction of nonsymbolic numerosities by deaf and hearing adults

Previous research has demonstrated that both hearing adults and hearing children with no training in arithmetic successfully performed approximate arithmetic on large sets of elements. Here, the possibility is explored that the same phenomenon can be confirmed in deaf adults who have acquired a signed language as their first language. Results reveal that they can perform simple arithmetic subtraction on nonsymbolic numerosities. Their performance levels were even higher than those of hearing adults who participated in the experiment as a control group. On the other hand, the performance levels of subtraction of the deaf adults in the formal mathematics were lower than those of the hearing adults. The findings are argued in terms of the characteristics of cognitive capabilities the deaf adults acquired through their development.

Promoting vocabulary learning in young children who are d/Deaf and hard of hearing: translating research into practice

Vocabulary knowledge is strongly associated with reading achievement and becomes increasingly predictive of overall reading proficiency as children progress through the elementary grades. Children who are d/Deaf and hard of hearing often begin schooling with small meaning vocabularies, a disadvantage that puts them at risk of struggling to learn to read. Recent research on vocabulary intervention with young children who have typical hearing demonstrates the effectiveness of targeted, contextualized instruction on children's word learning and provides insights for early childhood educators of young d/Deaf and hard of hearing children. In the present essay, which is grounded in the qualitative similarity hypothesis (Paul, 2010, in press; Paul & Lee, 2010) and sociocultural theories of learning, the author argues for evidence-based vocabulary interventions for young d/Deaf and hard of hearing children that are rooted in the contemporary research literature.     

Low-Tech vs. No-Tech: An evaluation of the impact of introducing presentation software into a criminal justice classroom

A study was conducted to measure the impact of using presentation software in a legal evidence class in a rural community college. The No-Tech group was taught through traditional teaching methods via chalk and blackboard, while the Low-Tech group received the same lectures utilizing computer generated presentation software. Although posttest measures did not reveal significant differences between the Low-Tech and No-Tech groups, several explanations are explored as to why this occurred, as well as recommendations on how to incorporate Low-Technology into the classroom setting.     

Individual differences in reading comprehension gains from assisted reading practice: pre existing conditions, vocabulary acquisition, and amounts of practice

We conducted a study of the effects of assisted reading practice (Shany & Biemiller, 1995). In this paper we examined the original data to find factors affecting gains in reading comprehension. We contrasted 14 children who had below median gains in reading comprehension and 15 who had above median gains. There were no significant correlations between pre-program language and reading measures and reading comprehension gains. High comprehension gainers made significantly larger gains in vocabulary. In the previous report on this research, we found that reading practice had large beneficial impact on reading comprehension. In this study we also found that children who gained significantly more vocabulary had also significantly higher gains in reading comprehension. Implications are discussed.     

Contribution of implicit sequence learning to spoken language processing: some preliminary findings with hearing adults

Spoken language consists of a complex, sequentially arrayed signal that contains patterns that can be described in terms of statistical relations among language units. Previous research has suggested that a domain-general ability to learn structured sequential patterns may underlie language acquisition. To test this prediction, we examined the extent to which implicit sequence learning of probabilistically structured patterns in hearing adults is correlated with a spoken sentence perception task under degraded listening conditions. Performance on the sentence perception task was found to be correlated with implicit sequence learning, but only when the sequences were composed of stimuli that were easy to encode verbally. Implicit learning of phonological sequences thus appears to underlie spoken language processing and may indicate a hitherto unexplored cognitive factor that may account for the enormous variability in language outcomes in deaf children with cochlear implants. The present findings highlight the importance of investigating individual differences in specific cognitive abilities as a way to understand and explain language in deaf learners and, in particular, variability in language outcomes following cochlear implantation.     

Language development in deaf children's interactions with deaf and hearing adults: a Dutch longitudinal study

The language development of two deaf girls and four deaf boys in Sign Language of the Netherlands (SLN) and spoken Dutch was investigated longitudinally. At the start, the mean age of the children was 3;5. All data were collected in video-recorded semistructured conversations between individual children and deaf and hearing adults. We investigated the lexical richness and syntactic complexity of the children's utterances in SLN and spoken Dutch, as well as language dominance and interactional participation. Richness and complexity increase over time, as well as children's participation. An important outcome is that syntactic complexity is higher in utterances with both sign and speech. SLN does not have higher outcomes on richness or complexity, but is dominant in terms of frequency of use.     

Conservation and metaphor acquisition in hearing-impaired children. Some relationships with communication mode, hearing acuity, schooling, and age.

This study focused on conservation and metaphor acquisition in 35 hearing-impaired children who used different modes of communication and who spanned a wide age range. Children who used either cued speech or oral-aural communication modes were tested at two different school sites. Relationships were determined between the dependent variables, conservation and metaphor, and the independent variables of age, degree of hearing loss, years of schooling, and mode of communication. Findings revealed a significant positive relationship between conservation and metaphor in both communication modes. Significant relationships between age and metaphor and between age and conservation were also found, suggesting that experience plays an important role in understanding both of them. Neither conservation nor metaphor was significantly related to either degree of hearing loss or communication mode. The conservation order of acquisition was number (91%), weight (60%), volume (50%), and liquid (46%). Suggestions for teachers based on the findings are presented.     

教法反思：传统与变革的观点

除特指教师的教与学生的学的双边意义，如教学相长 (teaching learning transaction)之外，通常情况下我们所说教学 (teaching)、教学法 (teaching method)其实主要是指教师的教或教法。因此本文提出并研究的教法，与通常说的教学法一致。我国的分科教学法，从形式上已经被改称为学科教学论，甚至是学科教育学，近几年其理论与实践的发展也十分繁荣，但从实质上看，即令在高师院校的研究生层次，它的发展似乎也还没有真正超越传统的教学法、教法范畴。教学法或教法，一直是课程与教材的附庸，近来甚至有大课程理论出现，要把教学法纳入课…     

When parents are deaf versus hard of hearing: patterns of sign use and school placement of deaf and hard-of-hearing children

This paper investigates the importance of knowing whether or not deaf and hard-of-hearing students have one or more deaf or hard-of-hearing parents. As noted by Mitchell and Karchmer (2004), deaf and hard-of-hearing school-age children and youth in the United States with at least one parent identified as hearing impaired are nearly evenly split between having at least one deaf parent and having at least one hard-of-hearing parent. However, there is no literature on the importance, if any, of this distinction. Findings from the investigation reported herein suggest that the distinction between having a deaf versus a hard-of-hearing parent is quite substantial, particularly as it pertains to the use of signing in the home. Further, signing in the home, which is reliably predicted by parental hearing status, is a significant predictor of the school setting in which the student is currently placed and the instructional use of signing in the classroom. Limitations related to the available measure of parental hearing status are discussed.     

儿童词汇习得理论述评

儿童在习得语言的过程中究竟怎样习得和学习词汇、词汇意义和指称,研究们从不同角度提出了不同的理论假设,并作了相应的实验研究。这些理论假设主要有：(1)花园变化学习理论,认为儿童学习词汇是一个联想式学习过程,即把语音与感性经验的显性方面联系起来。(2)制约原则论,认为儿童习得词汇除了通常的联想式学习过程外,还必须利用某种演绎限制机制,以便对词汇意义范围和指称范围做出限制。(3)社会语用理论,认为儿童习得词汇从本质上来说是完全社会化的过程,他们学习词汇不需要特定的语言限制,需要的是具有可塑性的、强有力的社会认知技能,儿童正是依赖这种技能去理解各种情境中交际的意图的。本对儿童词汇习得理论进行了综观研究,对各理论假设作了分析和述评。
