THE FACILITATIVE EFFECTS OF INCIDENTAL TEACHING ON PREPOSITION USE BY AUTISTIC CHILDREN

In a comparison of incidental teaching and traditional training procedures, three language-delayed autistic children were taught expressive use of prepositions to describe the location of preferred edibles and toys. Traditional highly structured training and incidental teaching procedures were used in a classroom setting, and generalization was assessed during free-play sessions. Results clearly indicate that incidental teaching promoted greater generalization and more spontaneous use of prepositions. These findings have important implications for language programming and teacher training, suggesting that incidental teaching should be included as a standard component of language development curricula for autistic and other developmentally delayed children.     

TEACHING AUTISTIC CHILDREN CONVERSATIONAL SPEECH USING VIDEO MODELING

We assessed the effects of video modeling on acquisition and generalization of conversational skills among autistic children. Three autistic boys observed videotaped conversations consisting of two people discussing specific toys. When criterion for learning was met, generalization of conversational skills was assessed with untrained topics of conversation; new stimuli (toys); unfamiliar persons, siblings, and autistic peers; and other settings. The results indicated that the children learned through video modeling, generalized their conversational skills, and maintained conversational speech over a 15-month period. Video modeling shows much promise as a rapid and effective procedure for teaching complex verbal skills such as conversational speech.     

Comparison of two discrimination methods in teaching Chinese children with autism

In teaching conditional discriminations to children with autism spectrum disorder (ASD), practitioners may progress from simple to conditional discriminations or may teach conditional discriminations from the onset of instruction. Some research indicates that teaching simple discriminations first may be unnecessary and that teaching may more efficiently focus on conditional discriminations exclusively. This study replicated comparisons of simple-to-conditional and conditional-only discrimination training methods in teaching audio-visual conditional discriminations to Chinese preschoolers with ASD. Results indicated the conditional-only training method appeared to be more efficient in teaching these skills.     

Recombinative reading derived from pseudoword instruction in a miniature linguistic system

A miniature linguistic system was used to study acquisition of recombinative symbolic behavior. Three studies evaluated the teaching conditions of conditional discriminations with printed and spoken pseudowords that could potentially generate recombinative reading. Fifty-four college students across all studies learned to match 12 printed pseudowords to 12 spoken pseudowords. Some also matched pictures to the same spoken words. Each two-syllable pseudoword was formed by symbols from an arbitrarily created alphabet composed of four vowels and four consonants. Letters had univocal correspondence with phonemes. Recombinative receptive reading, comprehensive reading, and textual responding to pseudowords were periodically assessed. Experiment 1 (n = 20) showed that recombinative reading increased as the number of trained words composed of the same symbols increased. Experiment 2 (n = 14) showed that overtraining the same two words did not produce recombinative reading for most participants. Experiment 3 (n = 20), in which training with pictures was omitted, showed that elemental control by within-syllable units can develop even when the trained pseudowords are meaningless (not related to pictures). The present results support the utility of the miniature linguistic system methodology for identifying and controlling environmental determinants of rudimentary reading skills.     

A comparison of blocked and mixed‐trial methods for teaching auditory–visual discriminations

Behavior analysts typically teach conditional discriminations in a mixed‐trial format but may switch to a blocked‐trial format for learners displaying limited acquisition. No known research has shown that mixed‐trial methods are more effective or efficient than blocked‐trial methods for teaching discriminations, so it is not clear why this format has been adopted as the “first‐line” intervention. We compared blocked and mixed‐trial formats for teaching novel auditory–visual discriminations to three adults with intellectual and developmental disabilities (IDD). Results show blocked‐trial methods resulted in faster skill acquisition in all cases, suggesting this format may be a preferable starting point for instruction.     

Some detrimental effects of using extra stimuli to guide learning in normal and autistic children

This study was designed to assess the effectiveness of using prompts (extra "guiding" stimuli) for teaching normal and autistic children. One group of normal children was pretrained on a color discrimination. Later, the colors were used as prompts (presented simultaneously with new training stimuli) to teach four new discriminations. Another group of normal children was trained on the same discriminations with a trial-and-error procedure (i.e., no prompting). A third group consisted of autistic children who were trained on these discriminations using the prompt procedure. Analyses of the results showed the following. (1) The trial-and-error group of normal children acquired more discriminations than the prompt group of normal children. (2) A comparison of the two prompt groups showed that the autistics failed to transfer from the prompt cue to the training cue more often than the normal children; rather, the autistics generally continued responding to the faded color cue. (3) Autistic and normal children who failed to acquire the discriminations when trained with a prompt procedure did acquire these discriminations when no prompt was used. That is, the results suggest that the presentation of an extra guiding stimulus was detrimental to the acquisition of training discriminations for all subjects, and particularly so far autistic children. Therefore, the common practice of providing extra guiding stimuli in proportion to the severity of the learning disorder may actually be harmful to the learning of new skills. Implications of these results for future research are discussed.     

Generalizing Effective Teaching Skills: The Missing Link in Teacher Preparation

A clear need to teach preservice teachers to generalize newly acquired teaching skills across time and settings has been well established in the literature. Few empirical studies exist that inform teacher educators on ways to promote generalization of teaching skills with beginning teachers, however. Programming for generalization continues to be a missing link between preservice teacher preparation and inservice application of skills. Four factors emerge as important to sustaining teaching skills in classrooms based on a review of the research. A model for promoting generalization of teaching skills using these factors is described including using immediate feedback to promote acquisition of skills, training to mastery to promote maintenance of behavior, programming for generalization, and providing performance feedback in classroom settings. Implications for teacher preparation are discussed such as requiring generalization training in teacher preparation programs and training supervisors to sequentially implement model components.     

PROMOTING RECIPROCAL INTERACTIONS VIA PEER INCIDENTAL TEACHING

This study evaluated peer incidental teaching as a strategy for increasing reciprocal peer interactions by children with autism. Three typical preschoolers were trained as peer tutors for 3 young children with autism. During a classroom free-play session, peer tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. A multiple baseline across the 3 target children showed replicated positive effects of the intervention. Adult supervision and assistance were then faded systematically, with resulting maintenance of increased reciprocal interactions. Multiple measures of the extent and limits of generalization suggested that 1 child increased interactions in free-play periods throughout the day, but none of the children showed increases at lunch. Teacher and peer ratings supported the social validity of positive findings.     

The effects of training on caregiver implementation of incidental teaching

A brief training package consisting of modeling, rehearsal, and feedback was evaluated to train caregivers to use incidental teaching to teach 3 children with autism to request an item or activity. The training package improved correct implementation of the incidental teaching procedure by caregivers. In addition, probes indicated that caregivers could apply these skills to teach the child an additional skill.     

Contextual analysis of home environment factors influencing the acquisition of early reading skills in Zambian families

This study examined the effect of home environment factors in the acquisition of early reading skills (orthographic awareness and decoding competence). To assess these factors, a sample of seventy-two (72) first grade learners (females?=?55%; age range?=?7–8 years) and their maternal parents (age range 26–61 years old) from low SES in Zambia's capital city, Lusaka were recruited. Parents, in response to a home literacy questionnaire, reported on their attitudes towards reading, literacy teaching in the home, the home literacy environment, presence of reading materials for adults and children, parental education, occupation, family size and family possessions. Two measures of reading skill were administered at school. Correlations revealed that parental education, occupation and the size of the family were not significantly associated with the reading measures. Family possessions, parental reading attitudes, literacy activities, and reading materials significantly predicted orthographic awareness. In predicting decoding competence, only family possessions, parental reading attitudes and literacy activities were predictive. Regardless of the context, children experience literacy in varied forms and quantities.     

The development of retrieval strategies in young children

Two incidental memory tasks were given to 3.5–6.5 yr old children to test for an age increase in the tendency to use a simple indirect retrieval strategy when direct retrieval efforts do not suffice. In both tasks, pictures of people were paired with very closely associated toy objects (e.g., farmer—toy tractor), and the indirect retrieval strategy consisted of thinking to use one member of the pair as a cue to the recall of the other, e.g., turning over the visible but facedown pictures and using them as retrieval cues for the toys. Support for the predicted age trend was obtained in one of the two tasks. It was suggested that the development of retrieval skills in children may show some parallels with that of storage skills.     

OBSERVATIONAL EFFECTS ON THE PREFERENCES OF CHILDREN WITH AUTISM

Children with an autism spectrum disorder (ASD) may play with limited objects or toys, making it difficult for teachers to identify reinforcers to use in teaching new skills. The goal of this study was to alter children's preferences from highly preferred toys to toys that were originally less preferred using an observational pairing procedure. Child participants observed a preferred adult playing with toys that were initially less preferred by the child. This intervention resulted in a shift in preference toward the item manipulated by the adult. Maintenance of the changed preference was idiosyncratic across participants. Results suggest a procedure for expanding the range of items that students with ASD will select.     

Teaching multiply controlled intraverbals to children and adolescents with autism spectrum disorders

Reciprocal conversations, instructional activities, and other social interactions are replete with multiply controlled intraverbals, examples of which have been conceptualized in terms of conditional discriminations. Although the acquisition of conditional discriminations has been examined extensively in the behavior‐analytic literature, little research has evaluated procedures to establish multiply controlled intraverbals. Thus, the purpose of this investigation was to evaluate the effects of procedures based on conditional discrimination training on the acquisition of multiply controlled intraverbals with 7 participants who had been diagnosed with autism spectrum disorders. We evaluated the effects of prompt delay with error correction, a differential observing response (DOR), and a DOR plus blocked trials on the acquisition of intraverbals using a multiple baseline design. Accuracy of intraverbal performance increased for at least 1 set of stimuli for all participants under prompt delay with error correction conditions; however, 4 participants required additional teaching (i.e., DOR, modified DOR, modified prompt delay with error correction). Based on these findings, when prompt delay with error correction is not sufficient to establish multiply controlled intraverbals, prompted DORs may be an effective alternative.     

Early language and the development of children's reading skills

There is considerable agreement that vocabulary plays a central role in reading acquisition, but there is less agreement about whether this association is direct or indirect through phonological and print-related knowledge. Longitudinal data from 77 African-American children were analyzed to examine the relationship between language skills, phonological knowledge and print processing skills at pre-kindergarten and kindergarten with reading at pre-kindergarten through second grade. Analyses indicated that home and child care experiences were related to reading indirectly through language and that language and phonological knowledge were both directly related to acquisition of reading skill. This study of African-American children and previous studies of lower- and middle-income children indicate both language and phonological skills play an important role in children becoming successful readers, and that experiences at home and in child care during in early childhood play a role in the acquisition of reading through their enhancement of early language and phonological skills.     

Factors influencing the selection of toys for handicapped and normally developing preschool children

Factors influencing the selection and purchase of toys for children's use were investigated. Subjects were 73 parents or adult friends of normally developing or handicapped preschool children. In addition to providing demographic information about themselves, the subjects rated the importance of 17 factors influencing their selection and purchase of toys. Contrary to previous research, the sex of the child was reported to be of only minor importance in toy selection, as was the picture on the toy package. Two factors, safety and teaching new skills, were rated as extremely important. There were no significant differences in ratings as a result of sex, ethnicity, or whether or not the subjects were parents of a handicapped child. The findings suggest a substantial degree of agreement among parents about what they consider important when choosing toys for children.     

The contribution of short-term memory for serial order to early reading acquisition: evidence from a longitudinal study

Early reading acquisition skills have been linked to verbal short-term memory (STM) capacity. However, the nature of this relationship remains controversial because verbal STM, like reading acquisition, depends on the complexity of underlying phonological processing skills. This longitudinal study addressed the relation between STM and reading decoding acquisition by distinguishing between STM for item information and STM for order information based on recent studies showing that STM for item information, but not STM for order information, recruits underlying phonological representations. If there is a specific link between STM and reading decoding acquisition, STM for order information should be an independent predictor of reading decoding acquisition. Tasks maximizing STM for serial order or item information, measures of phonological abilities, and reading tests were administered to children followed from kindergarten through first grade. We observed that order STM capacity, but not item STM capacity, predicted independent variance in reading decoding abilities 1 year later. These results highlight the specific role of STM for order in reading decoding acquisition and argue for a causal role of order STM capacity in reading acquisition. Mechanisms relating STM for order information and reading acquisition are discussed.     

A Meta-analytic Review of Components Associated with Parent Training Program Effectiveness

This component analysis used meta-analytic techniques to synthesize the results of 77 published evaluations of parent training programs (i.e., programs that included the active acquisition of parenting skills) to enhance behavior and adjustment in children aged 0-7. Characteristics of program content and delivery method were used to predict effect sizes on measures of parenting behaviors and children's externalizing behavior. After controlling for differences attributable to research design, program components consistently associated with larger effects included increasing positive parent-child interactions and emotional communication skills, teaching parents to use time out and the importance of parenting consistency, and requiring parents to practice new skills with their children during parent training sessions. Program components consistently associated with smaller effects included teaching parents problem solving; teaching parents to promote children's cognitive, academic, or social skills; and providing other, additional services. The results have implications for selection and strengthening of existing parent training programs.     

Multisensory letter integration and implicit learning of reading with 5-year-old children

IntroductionSeveral studies have shown that adults can memorize an audio-visual association in response to an incidental presentation. Moreover, a motor experience of the letter-shape promotes letter knowledge and reading acquisition.ObjectiveIn order to develop optimal learning designs for children, we evaluate the effect of the implicit learning of grapho-phonemic correspondences on decoding abilities (study 1). The action performed on the letter-shape in this type of learning was then also investigated with regard to the emergence of multisensory knowledge (study 2).MethodsA paradigm inspired by studies conducted with adults was tested in 5-year-old children (study 1). A classical design pre-test/learning/post-test was used in the study 2. During the learning, the child was asked to explore the letter shape. An incidental presentation of the corresponding sound was simultaneously proposed to the child.ResultsResults indicated that (1) implicit learning was efficient on the discrimination of grapho-phonemic correspondences in young children and (2) the motor action amplified audio-visual integration within a single memory trace.ConclusionThese results are discussed in the light of knowledge emergence in long-term memory and the benefit of an implicit training at the beginning of reading acquisition.     

Incidental teaching of language in the preschool

"Incidental teaching" denotes a process whereby language skills of labelling and describing are learned in naturally occurring adult-child interactions. In the present study, 15-min daily samples of the spontaneous speech of 11 children were recorded during free play over eight months of preschool. After incidental teaching of compound sentences, increases in unprompted use of compound sentences were seen for all the children, first directed to teachers, and then to children, in accordance with who attended to the children's requests for play materials. The incidental teaching procedure also stimulated spontaneous variety in speech, and appears to have general applicability to child learning settings.     

Factors Influencing the Selection of Toys for Handicapped and Normally Developing Preschool Children

Contrary to previous research, the sex of the child was reported to be of only minor importance in toy selection, as was the picture on the toy package. Two factors, safety and teaching new skills, were rated as extremely important. There were no significant differences in ratings as a result of sex, ethnicity, or whether or not the subjects were parents of a handicapped child. The findings suggest a substantial degree of agreement among parents about what they consider important when choosing toys for children.
