A comparison of self-instructional checking procedures for remediating mathematical deficits

We examined the relative effectiveness of three procedures for teaching long multiplication/division to seven adolescents with learning disabilities: no-checking, end-checking, and multi-checking. During training, each subject was taught by modelling and imitation to verbalize self-instructions in the form of a strategy while solving the problems. The relative effects of the checking and no-checking procedures on accuracy and rate of problems completed were examined in an alternating treatments design. The best treatment was then given alone and a reversal was implemented six weeks later, followed by a return to the best treatment during a final phase. Irrespective of the procedure used, the subjects' accuracy improved while the rate of problems completed decreased. These effects were greatest with the multi-checking procedure for six of the seven subjects. Generalization to untaught problems of various levels of complexity occurred under all procedures. Though maintenance effects were seen during the follow-up, accuracy was generally higher and more reliable when the subject's best checking procedure was reinstated. It is suggested that error detection and correction were important for maintaining high levels of accuracy and that these operated differentially in the three procedures to produce the differing levels of accuracy. The role of other factors such as pre-skill knowledge, complexity of the problem and prior reinforcement history are also considered.     

Instructive feedback: A comparison of simultaneous and alternating presentation of non-target stimuli

Instructive feedback involves presenting extra, non-target stimuli in the consequent events for children's responses. Two methods of presenting instructive feedback during direct instruction were compared. These methods involved presenting two extra stimuli on all trials, and presenting the two extra stimuli separately on alternating trials. Preschool students were taught coin combinations using a constant time delay procedure with instructive feedback stimuli added to both praise and correction statements. An adapted alternating treatments design was used to evaluate the two methods of presenting instructive feedback. The students were assessed to determine the extent to which instructive feedback stimuli were learned. The results indicate that students learned some of the instructive feedback stimuli and no consistent differences in the effectiveness of the two presentation methods were noted. Further, relationships between the two instructive feedback stimuli appeared to be established. Implications for instruction and future research are discussed.     

Father and mother contributions to family functioning when the child has a mental delay

Less is known about the father's than the mother's role in family adaptation to children with disabilities. The purpose of this study was to examine relationships of both father and mother use of coping strategies and perceptions of the child with measures of family functioning style. Subjects were 26 families of 30-month-old children with a mental delay and a comparison group of 26 families of same-aged children with no delay. Functioning style for study families showed a balance of cohesion and adaptability; comparison families were more chaotically flexible on the adaptability scale. Mothers and fathers agreed on family functioning style. Study parents made the greatest use of external coping strategies, while in both groups mothers used more external and fathers more internal coping strategies. Relationships between coping and family functioning varied by parent and by group. Results suggest the need for further exploration of the separate needs of fathers and mothers in maintaining balanced family functioning.     

Voluntary parents to multiple children with special needs: A profile

A sample of 18 women and men who accompanied their foster or adopted children with severe developmental disabilities to a medical appointment at Henry Ford's Multidisciplinary Care Clinic during the one-year period and who reported during that appointment that they currently had residing with them at least three foster or adopted children with special needs are described in the context of their parental role vis-a-vis these children. Results of the study are presented through use of a six-part organizational scheme: demographic and social traits of the parents and their focal children (the children being seen at the Clinic that day), the focal children in family context, life satisfactions of the parents, foster or adoption motives (whichever applied), foster or adoption satisfactions, and parental sentiments regarding the children as a group.     

TRAINING INTERACTIONAL BEHAVIORS OF ADULTS WITH DEVELOPMENTAL DISABILITIES: A SYSTEMATIC REPLICATION AND EXTENSION

This study was a replication and extension of research by Foxx, McMorrow, Bittle, and Ness (1986) that assessed generalization effects of a social skills training program on the interactional behavior of adults with developmental disabilities. Target skills were a verbal action or reaction in six skill areas that specifically addressed the participants' skill deficits. In the present study, we trained 5 adult residents of a group home across these six skill areas using the “Sorry” game format and the scoring criteria described by Foxx et al. We extended the results of Foxx et al. by (a) using pretreatment assessment procedures to identify participants' specific skill deficits, (b) training all residents in the natural environment, (c) training participant—participant interactions, (d) training participants to respond to four of the six skill areas through the use of a role-play procedure, and (e) omitting rewards, criterion levels, and self-monitoring. Additionally, the trainer in the present study modeled correct responses only as an error correction procedure during training. Similar to those of Foxx et al., our results indicated that all participants increased their use of the trained interactional behaviors during the generalization assessments in the presence of other trained peers.     

TEACHING PERSONS WITH PROFOUND MULTIPLE HANDICAPS: A REVIEW OF THE EFFECTS OF BEHAVIORAL RESEARCH

The behavioral research on teaching individuals who have profound multiple handicaps is reviewed. The primary focus is on determining the degree to which behavioral research has demonstrated the teaching of meaningful skills to this population. Results of the review indicate that investigations have demonstrated, albeit inconsistently, that behavior change has resulted from contingency management interventions with persons who have profound multiple handicaps. However, there is little evidence that such interventions have resulted in meaningful behavior change according to currently accepted criteria for beneficially affecting the quality of life of persons with serious handicaps. Potential explanations for the lack of such evidence are offered, including the relative lack of research attention given to this issue, the possible ineffectiveness of the components of the technology applied, and possible ineffective application of the potentially effective technology. Suggestions for future research are discussed in terms of developing more effective educational and habilitative services for persons with profound multiple handicaps. In particular, we suggest research on a wider variety of behavioral teaching procedures, providing more comprehensive evaluations of the applications of procedures and developing treatment programs that do not focus solely on traditional skill acquisition.     

THE EFFECTS OF SEVERE BEHAVIOR PROBLEMS IN CHILDREN ON THE TEACHING BEHAVIOR OF ADULTS

Applied behavior analysts have focused on how adults can influence the problem behavior of children using a variety of behavior modification strategies. A related question, virtually unexplored, is how the behavior problems of children influence adults. This child-effects concept was explored empirically in a study involving 12 adults who were asked to teach four pairs of children in which one member of the pair exhibited problem behavior and the other typically did not. Results demonstrated that problem children displayed tantrums, aggression, and self-injury contingent on adult instructional attempts but not at other times, whereas nonproblem children showed little or no problem behavior at any time. Importantly, from a child-effects perspective, adults engaged in teaching activities with nonproblem children more often than with problem children. Also, when an adult worked with a problem child, the breadth of instruction was more limited and typically involved those tasks associated with lower rates of behavior problems. The implications of these results are discussed with respect to theories of escape behavior, current assessment practices, and intervention issues related to maintenance. The existence of child effects suggests that problem behavior may be better understood when it is conceptualized as involving a process of reciprocal influence between adult and child.     

Young adults with intellectual and other developmental disabilities acquire vocational skills with video prompting

Students with intellectual and other developmental disabilities often require substantial support to acquire the skills needed to secure work experience and paid employment. Prior findings suggest that video prompting is likely to be an effective and feasible strategy for establishing such skills. To evaluate this possibility in a special education transition program, we examined the effectiveness of a video prompting procedure in teaching 8 young adults with developmental disabilities to perform job-related tasks (doing laundry, checking in to work, vacuuming, stripping bed). The intervention was effective with all participants. The skills maintained over 3 months, and the participants performed the tasks accurately in a new setting with different materials. Participants were reportedly satisfied with the intervention and deemed it easy to use.     

Coding infant engagement in the Face-to-Face Still-Face paradigm using deep neural networks

BackgroundThe Face-to-Face Still-Face (FFSF) task is a validated and commonly used observational measure of mother-infant socio-emotional interactions. With the ascendence of deep learning-based facial emotion recognition, it is possible that common complex tasks, such as the coding of FFSF videos, could be coded with a high degree of accuracy by deep neural networks (DNNs). The primary objective of this study was to test the accuracy of four DNN image classification models against the coding of infant engagement conducted by two trained independent manual raters.Methods68 mother-infant dyads completed the FFSF task at three timepoints. Two trained independent raters undertook second-by-second manual coding of infant engagement into one of four classes: 1) positive affect, 2) neutral affect, 3) object/environment engagement, and 4) negative affect.ResultsTraining four different DNN models on 40,000 images, we achieved a maximum accuracy of 99.5% on image classification of infant frames taken from recordings of the FFSF task with a maximum inter-rater reliability (Cohen's κ-value) of 0.993.LimitationsThis study inherits all sampling and experimental limitations of the original study from which the data was taken, namely a relatively small and primarily White sample.ConclusionsBased on the extremely high classification accuracy, these findings suggest that DNNs could be used to code infant engagement in FFSF recordings. DNN image classification models may also have the potential to improve the efficiency of coding all observational tasks with applications across multiple fields of human behavior research.
