Determinants of acquiescence and naysaying of mentally retarded persons.

Social desirability and intellectual limitations were investigated as possible determinants of two response biases--acquiescence and naysaying--among mentally retarded respondents. Results clearly indicated that naysaying and acquiescence occur more frequently among lower IQ individuals and naysaying occurs more frequently concerning prohibited behavior, whereas respondents acquiesce regarding desirable behavior. These results suggest that intellectual limitations predispose people to biased responding, whereas social desirability factors determine the type of bias.

Children's judgements about psychological harm in social context.

72 children, ages 6 to 11 years, were presented with a series of stories involving psychological harm (name-calling) in a game context. Situations were presented in which intentions, consequences, and game context were varied, along with order of story presentation. Comparison between acts of physical and psychological harm were also conducted. Although responses in some conditions were influenced by order of presentation, age differences were found in children's evaluations of agents' actions and recipients' reactions for psychological harm in game contexts. Younger children were more likely to ignore intentions and consequences or the recipient's perspective and to focus on contextual features (e.g. game rules). Older children were more likely to base their evaluations on intentions, or both intentions and consequences, and to take into account the recipient's perspective. Game context interacted differentially with psychological and physical harm at all ages. Evaluations of acts of physical harm were more likely than acts of psychological harm to be transformed by game context.

Modifying maternal teaching style: effects of task arrangement on the match-to-sample performance of retarded preschool-age-children.

Twenty-one mothers and their retarded preschool-age children were observed during six teaching sessions. Following the first three sessions, each mother-child dyad was assigned to one of the three groups. Groups were matched on measures of mother and child behavior and on measures of various mother and child background factors. Prior to the last three teaching sessions, mothers received instructions to modify certain aspects of their teaching style. The results indicated that children of mothers who had been instructed to present the materials of the task systematically obtained significantly higher performance scores during training than did children of mothers who either received no instruction or had been told to increase positive feedback for correct responses. Further, 6 of 7 children whose mothers had altered the manner in which they presented the task materials showed improvement on a test administered after training. These results suggest that nonverbal activities which precede responding are critical aspects of teaching style and deserve more attention than they have received in the past.

An attributional intervention to reduce peer-directed aggression among African-American boys.

An attributional intervention was designed to reduce aggressive males' tendency to attribute hostile intentions to peers following ambiguously caused peer provocations. African-American elementary school boys (N = 101), aggressive and nonaggressive, were randomly assigned to the attributional intervention, an attention training program, or a no-treatment control group. Data were collected on subjects' attributions about hypothetical and laboratory simulations of peer provocation, disciplinary referrals to the school office, and teacher ratings of aggressive behavior. Aggressive subjects in the attributional intervention were less likely to presume hostile intent by peers in hypothetical and laboratory simulations of ambiguous provocation. They were also less likely to endorse hostile retaliation on judgment measures and to engage in verbally hostile behaviors in the laboratory task. Further, intervention subjects were rated as less aggressive by their teachers following the treatment. Both the benefits of attributional change and its limitations in the African-American population are discussed.

Verb schema use and input dependence in 5-year-old children with Specific Language Impairment (SLI).

BACKGROUND: It has been argued that children with Specific Language Impairment (SLI) use language in a conservative manner. For example, they are reluctant to produce word-plus-frame combinations that they have not heard in the input. In addition, there is evidence to suggest that their utterances replicate lexical and syntactic material from the immediate language environment. AIMS: This study investigated further the linguistic conservatism of children with SLI. It addressed the hypothesis that these children have difficulties using syntactic schemas in a verb-general manner. It employed a technique pioneered by Childers and Tomasello in 2001 that aims to develop verb-general representations through the presentation of appropriate exemplars. In addition, it tested the hypothesis that children with SLI present with input-dependent language use. METHODS & PROCEDURES: Twenty-four children with SLI (mean age 5;6 years) were matched to 23 typically developing children (mean age 3;5 years) on overall language abilities. The children experienced play sessions designed to simulate exemplar-based learning. Facilitative exemplars consisted of sentences that alternated between nouns and pronouns in the argument slots, e.g. 'Pooh's churning the plate. See, he's churning it'. The children were divided evenly into two groups. One group experienced facilitative exemplars, while the other group heard exemplars with no variation in the argument positions. The training effect was assessed with a procedure in which the children heard novel verbs in a non-transitive frame and were required to produce them in a transitive frame. In addition, the argument types of the children's responses (nouns versus pronouns) were analysed to investigate the issue of input dependence. OUTCOMES & RESULTS: Few of the children produced novel verbs in the transitive. This result may indicate difficulties using the transitive, although a number of methodological difficulties may be responsible for this finding. As hypothesized, the children with SLI demonstrated greater input dependence in terms of the kind of arguments they used in responses during the training sessions. CONCLUSIONS: Potential reasons for the low response rate of both groups during the testing stage are explored and a number of methodological adjustments proposed. It is argued that the greater input dependence of the children with SLI may reflect a tendency to reduce processing load within a limited capacity system. It is proposed that input dependence could be a fruitful new area for SLI research and an important issue in the design and delivery of therapy programmes.

An evaluation of the relationship between receptive speech skills and expressive signing.

We examined the effects of receptive speech on the acquisition of manual signing among three mentally retarded children. In an alternating treatments design, we compared the acquisition of expressive signs that were, versus were not, in a child's receptive vocabulary. The children were trained via total communication in which pictorial referents were named during sign training. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. We conducted posttests to assess the stimulus control of signing and any changes in expressive and receptive signing and speech. Observed changes in performance could be accounted for by attention to aspects of the stimulus complex during training and functional equivalence of stimuli established by training.
