Grouping strategies, peer influence, and free time as classroom management techniques with first- and third-grade children

This study systematically investigated the effects of different procedures on classroom behaviors ranging from teacher designated seating groups and seating groups based on sociometric data to peer encouragement and free time reinforcers. Subjects were first- and third-grade children in classrooms using a Follow Through program model. Data were taken on the attending behavior of the children in small groups arranged by the teacher. The level of appropriate attending behavior was low and did not increase when the groups were restructured based on sociometric data. The introduction of instructions to the peer groups to help the child with his or her work brought about a major increase in the third-grade subjects' appropriate behavior. Appropriate attending behavior for the first-grade children did not increase to the predetermined acceptable level until a free time period for each peer group was made contingent upon the appropriate behavior of the subject in each group. Frequencies of verbal interactions suggested peer attention has an effect on the appropriateness of peer interactions.     

The program for academic survival skills (pass): Effects on student behavior and achievement

The effects of the Program for Academic Survival Skills (PASS), a group behavior management program, on behavioral observation data and standardized achievement test measures were investigated. Fifty-four of the 96 selected low-achieving, low-survival-skill students of normal IQ were assigned to an experimental condition in which their teachers used PASS. The remaining 42 were assigned to a control condition. Results indicated PASS produced significant gains in survival skills during its operation and one week following program termination in both reading and mathematics periods across grades 1–3. Findings for achievement indicated a significant gain for first-grade experimentals only in reading, with a similar but nonsignificant gain for first-grade mathematics.     

Recognition memory in mentally retarded persons

The continuous recognition memory of retarded and normal subjects was assessed. The stimuli were magazine pictures, arranged so that lags of up to 250 pictures occured. The overall performance of the retarded subjects was poorer, in terms of hit rate or d′. However, the differences were present at 0 lag and the slopes of the forgetting curves were similar in both groups. It was concluded that differences between these subjects were due to a perception related process and not to memory.     

Establishing generalized verb-noun instruction-following skills in retarded children

A transfer of stimulus control procedure was used to establish generalized verb-noun instruction-following skills in two severely retarded boys. Each of 12 verbs was trained, in a multiple baseline order, to criterion with each of 12 nouns in the form of verb-noun verbal instructions. Throughout training, reinforced probes were conducted on both trained and untrained verb-noun combinations. As training progressed, both subjects began to respond correctly to untrained verb-noun instructions. Eventually, a verb needed to be trained in combination with only one noun before generalization occurred to the as-yet-untrained 11 verb-noun instructions involving that verb.     

Eliminating selective stimulus control: a comparison of two procedures for teaching mentally retarded children to respond to compound stimuli

Selective stimulus control occurs when behavior fails to come under control of all characteristics of a compound stimulus after discrimination training. Two different assessment procedures, one used in prior research and the other incorporating incorrect stimuli (S - 's) which differed minimally from the correct stimulus (S+), were used to detect stimulus control deficits characteristic of selective stimulus control. The efficacy of two training procedures in eliminating selective stimulus control observed with three trainable mentally retarded children was evaluated in Experiment 1. A training procedure using S - 's that were minimally different from the S+ was designed to reduce the probability that stimulus discriminations could be based on stimulus characteristics other than experimenter-specified characteristics defining the S+. This procedure proved more effective in preventing and eliminating selective stimulus control as measured by both assessment procedures than an alternate discrimination training procedure that failed to impact the more stringent measures of selective stimulus control. Experiment 2 indicated that these improvements in stimulus control were not a function of varying degrees of difficulty between stimulus sets or of a prior history of discrimination training with the less effective training procedure. The need for better assessment procedures to detect selective stimulus control and suggestions for further improvements in discrimination training procedures are discussed.     

Do the mentally retarded have poor memory?

The hypothesis that mentally retarded persons have a short-term memory deficit whixh is due to inadequate rehearsal strategies is reexamined. A reevaluation of results of a number of experiments suggests that normal and retarded persons differ on short-term memory tasks, and the superiority of normals is present from the time of initial stimulus exposure. While some evidence for slope differences in retention curves is found in a few tasks, it is not strong support for memory differences. The hypothesis that “memory” differences are due to differential encoding as a result of more adequate rehearsal by the normal subjects is unacceptable. If this were the case, some differences in slope of retention curves could be expected unless rehearsal beyond the encoding stage was totally precluded. The review points to a need for an empirical reevaluation of the issue with a full recognition that deficits in particular processes may characterize some retarded persons and not others.     

The effects of parent-presented models and praise on the vocal behavior of their children

The combined and separate effects of parent-presented models and praise on specific vocalizations of three children (15, 17, and 20 months old) were investigated. The frequency of a specific vocalization was higher when parents modeled and praised it than when they did not. In addition, modeling and praise, when used in combination, had a greater effect on the frequency of specific vocalizations than when used separately. Three additional parents were asked to attempt, by any means they wished, to increase the frequency of a specific vocalization by their children. These parents used modeling almost, exclusively, and the children did not exhibit the specific vocalizations as frequently as did the children whose parents were instructed both to model and praise specific vocalizations.     

Free recall and retrieval speed of categorized items by kindergarten children

Kindergarten Ss were presented with 16 pictorial items in four category sets or a partially random ordem with one item from each category composing the four presentation sets. The pictures were presented either on conceptually related background pictures or on white backgrounds. The categorically grouped presentation facilitated free recall performance, both in terms of number of items recalled and the speed with which the items were recalled, and increased the amount of clustering in recall. Categorical clustering in recall was associated with shorter within- than between-category intervals and for those Ss who recalled items from each of four categories successively, the over-all temporal pattern in recall closely approximated that found with adults. No background effects were found.     

Speech acquisition in a nonverbal isolate child

The present study attempted to evaluate experimentally the relationship between two response classes: cooperative play and speech. One child was observed in a preschool free-play setting. Base rates of speech and play with peers indicated that the child never spoke to or played with peers during free-play periods. Base rates of teacher attention were observed to fluctuate directly with the child's isolate play. When differential attention and extinction operations were presented, removed and presented again, the frequency of cooperative play with peers increased, decreased and increased accordingly. Moderate fluctuations in verbal behavior also correlated with the presence and absence of the differential attention and extinction operations, even though the operations were applied only to cooperative play. The results suggest that some nonverbal isolate children may begin producing speech when play behaviors with peers are reinforced by teachers.     

Behavioral inference in young children

Three experiments are reported on behavioral inference in children of 3 to 5 years of age. In each experiment the children learned two separate sequences of behavior which they were required to put together in the final test stage in order to obtain a reward. In the first experiment moderate levels of behavioral inference were obtained, although a relatively high proportion of children failed to respond in the test phase. In the second experiment different instructions were used in the test phase, the number of nonresponders was greatly reduced and a much higher proportion of children showed behavioral inference. The third experiment obtained similar results under conditions which excluded the possibility of mediation during a memory test, which was included in the previous experiments. It was concluded that behavioral inference is found, under suitable conditions, in children as young as 3-years-old, and that reports by other investigators of failure to find such inference up to the age of about 8 were due to problems with apparatus and instructions.     

A study of some conditions relating to the retarded adult's stereotyped responding in a binary-choice task

This study was a longitudinal one that examined the effects of certain conditions on alternation and perseveration in a binary-choice task. The conditions manipulated included: (1) lapse of time (stability of the pattern), (2) stimulus dissimilarity, (3) spatial location of the two alternatives, (4) time-out (time away from the task), (5) delay between responses, and (6) differential reinforcement of the two choices. Eight mentally retarded adults, identified as “pure” alternaters or perseveraters, served as subjects. Perseveration was “disrupted” only by differential reinforcement. Alternation was affected by all experimental manipulations with the exception of stimulus dissimilarity.     

Training strategic study time apportionment in educable retarded children

Two groups of educable retarded children differing in functioning level served as subjects. One group, the High group, consisted of 31 children drawn from the upper two classes of a five-class stream. The Low group consisted of 39 children drawn from the lowest two classes. During pretesting, on each trial but the first of a multitrial free recall procedure, subjects were allowed to select half of the to-be-remembered items to see if they would strategically select missed items for extra study. Following pretesting, subjects were divided for training into three groups for which the experimenter selected items for study: in the Standard group, missed items; in the Creeping group, recalled items plus one missed item; and in the Random group, half missed and half recalled items. Children in the High group improved in the Standard condition, and those in the Low group benefited from Creeping training. There was no evidence of maintenance of training in the Low group, but children in the High group given training in the standard strategy selected missed items for recall on the posttests. The results are discussed in terms of the stability of trained strategies in retardates, and the question of what constitutes an optimal strategy is considered.     

Perceptual centres for Dutch digits

In two experiments, analogous to those reported by Marcus (1976) with English words and subjects, we determined the psychological moment of occurrence (p-centre) of Dutch digit names. In the first experiment we determined the p-centres for the digits 1 through 10 and compared the empirical results with values calculated from the formula that Marcus defines over the acoustic characteristics of stimulus words. We found good agreement between empirical and predicted values. In a second experiment we studied the effect of cycle time and repeated measurement on perceptual centres. The results confirm the independence of the p-centre phenomenon from practice and periodicity. A comparison of ‘identical’ and ‘non-identical’ stimulus pairs shows that larger variances are associated with the former condition.
