Instructive feedback: Effects of number and type

We evaluated the effects of presenting two instructive feedback stimuli of the same and different types for each target behavior taught. Four elementary school students with mild mental retardation were taught to name photographs of places of interest in the local community using constant time delay and instructive feedback. Initially, the four students were taught one set of photographs with one instructive feedback stimulus (name of the street on which the place was located) for each target photograph. All students learned to name all photographs, and three learned to name the street on which the place was located. The three students who learned to name the street for the place in the photograph were then taught three sets of photographs. Each set included two instructive feedback stimuli for each target photograph: Set 2 had one street name and one activity that occurred in the place; Set 3 had two activities per photograph, and Set 4 had one street name and one activity. The three students learned to name the photographs, but only learned to name the activities and not the street names that were presented through instructive feedback. These finds are discussed in terms of the factors that may control acquisition of instructive feedback stimuli and the implications for practice and future research.     

Instructive feedback: Review of parameters and effects

We present a review of the existing research on instructive feedback. Instructive feedback is a method of presenting extra, non-target stimuli in the consequent events of instructional trials (e.g., during praise statements). Students are not required to respond to those additional stimuli and are not reinforced if they do. The research is reviewed in terms of the characteristics of participants involved, the settings and instructional variables used, and the findings that emerged. The findings indicate that a wide range of students by age and disability were included and that most studies occurred in special education contexts. When used with response prompting procedures in a variety of direct instructional arrangements, students acquire and maintain some of the instructive feedback stimuli. Thus, teachers are encouraged to use instructive feedback in their direct instructional activities. Areas of future research include using instructive feedback in new contexts and examining methods for presenting instructive feedback. In addition, the use of instructive feedback to influence future learning and stimulus class formation should be investigated.     

Effects of daily probing on acquisition of instructive feedback responses

This study evaluated the effects of daily probes of instructive feedback stimuli on students' acquisition of two types of instructive feedback responses. Four students, two with disabilities, participated and were taught four sets of behaviors, two sets received daily probes and two sets did not. A modification of the multiple probe design across behaviors was used. The findings indicate that students acquired their target behaviors rapidly and maintained correct responding during subsequent probe conditions. Students also acquired both types of instructive feedback and maintained it across subsequent probe conditions. The daily probes of the instructive feedback stimuli did not appear to enhance acquisition or maintenance of the instructive feedback responses, but students appeared to acquire the instructive feedback responses while learning their target behaviors. The implications of this study for understanding how students learn instructive feedback responses and for practice are discussed.     

Comparison of simultaneous prompting with and without error correction in teaching science vocabulary words to high school students with mild disabilities

This study compared the effectiveness and efficiency of simultaneous prompting with and without error correction during daily probe sessions in teaching science vocabulary words. The teacher presented the vocabulary word definitions as instructive feedback during training sessions. Five 16–17 year old students with disabilities participated in an adapted alternating treatments design that evaluated the simultaneous prompting strategy, error correction and instructive feedback. Instruction occurred in a group format using choral responding. The results indicate that (a) all students learned to read the vocabulary words, (b) simultaneous prompting with error correction was slightly more efficient for three of the five subjects in learning the targeted words, and four of the five students made fewer errors in this condition, (c) all students preferred simultaneous prompting with error correction over simultaneous prompting without error correction, (d) words mastered in both conditions generalized equally, (e) there were minimal differences between the two conditions in the collected maintenance data, and (e) students experienced only minimal improvement in their ability to define vocabulary words (instructive feedback). Discussion focuses on issues for further research and implications for instructional practice with simultaneous prompting, error correction and instructive feedback.     

Effects of presenting incidental information in consequent events on future learning

The effects of presenting future target stimuli in the consequent event following correct responses to current target stimuli were examined in two experiments teaching eight students with moderate handicaps to name photographs. In Experiment I, progressive time delay was used to teach two sets of photographs. During instruction, correct responses to one set of stimuli resulted in praise and presentation of the printed word for the person in the photograph (future condition). In the second set, a correct response was followed by praise alone (non-future condition). After establishing criterion level performance on both sets of photographs, students were taught to read the printed word from each of the two sets. Experiment II was a systematic replication of Experiment I. Four students from a different classroom also were taught to name two sets of photographs. An adapted alternating treatments design was used in each experiment. The results indicated that (a) all students learned to name the photographs; (b) presentation of future target stimuli (words) in consequent events resulted in seven of the eight students learning to read some of the words; and (c) the total number of sessions, trials, errors, and percentage of errors     

Embedding instructive feedback into teacher-student interactions during independent seat work

The effects of embedding a constant time delay procedure into an independent seat work activity and using instructive feedback were evaluated in this study. Seven students with mild disabilities participated in the study that occurred in their special education classroom. A multiple probe design across sets of target behaviors was used, and students' responses to instructive feedback stimuli were evaluated during each probe condition. The procedures were implemented with a high degree of fidelity, and the results indicate that (a) the students acquired the target behaviors taught with the constant time delay procedure that was embedded into independent seat work, and (b) the students acquired some but not all of the responses to the instructive feedback stimuli. These findings are discussed in terms of using instructive feedback in classrooms and future research on instructive feedback.     

Examination of variables that affect the efficacy of instructive feedback

Instructive feedback is a procedure in which additional, nontarget stimuli are presented during instructional trials for students with a wide array of disabilities. This preliminary investigation examined whether participant behavior during instructive feedback, including attending and echoic behavior, altered the efficacy of instructive feedback for 2 children with autism. Results showed that participant behavior during instructive feedback related to training outcomes for both participants and treatment modifications based on participant behavior influenced acquisition. Future directions of research and implications for practice are discussed.     

Teaching peer reinforcement and grocery words: An investigation of observational learning and instructive feedback

A multiple probe across behaviors design, replicated across participants, assessed the effectiveness of constant time delay in teaching appropriate peer reinforcement and grocery words to 3 elementary students with moderate intellectual disabilities. Additionally, pretests and posttests assessed the acquisition of the participants' observational learning (acquisition of peers' grocery words) and instructive feedback (related information supplied by the teacher in the consequent event). Results indicate that the participants learned (a) how to appropriately reinforce peers, (b) to read their grocery words, (c) some of the targeted stimuli of their peers, and (d) much of the instructive feedback that was associated with each of the grocery words. Maintenance data indicate that the participants maintained their target grocery words at high levels of accuracy.     

The effect of aural feedback in second language vocabulary learning

We examined instructional procedures in the teaching of second language vocabulary, using a paired-associate paradigm. Four presentation methods were investigated, including simultaneous standard, simultaneous reversal, aural feedback, and visual feedback. The study involved 16 grade 7 school children as subjects. Subjects were tested on 28 second language words during the post-test stage. Orthogonal comparisons were carried out for the obtained data. The two feedback conditions proved to be the most beneficial and the more favourable out of these was the aural feedback condition. Also, reversing the two inputs proved to be better than the conventional paired-associate (e.g. presenting the second language word first with the first language word second). Based on the results of this study, it is advocated that the feedback procedures, in particular, be used in second language learning with aural feedback replacing visual feedback.     

Preconditioning of reinforcing properties to an exteroceptive feedback stimulus

Three groups of rats were given Pavlovian preconditioning by means of a yoking procedure and subsequently trained to avoid. One group received a light stimulus during preconditioning at the same times as the master avoiding animals received an exteroceptive feedback stimulus. During the subsequent avoidance training, this group was then given the same light stimulus as a feedback stimulus on successful avoidance trials. The group learned two-way avoidance in about the same number of trials as one-way avoidance is typically learned and substantially faster than two other control groups. These data indicate that feedback stimuli develop reinforcing properties by a Pavlovian mechanism. The data of the control groups indicate that feedback stimuli do not provide “information” about responding in the present situation.     

Simultaneous Prompting and Instructive Feedback When Teaching Chained Tasks

This study evaluated the effectiveness of the simultaneous prompting procedure when teaching students with moderate to severe mental retardation a chained task (i.e., hand washing). This study also evaluated if students could acquire responses to instructive feedback stimuli presented during training sessions. The effectiveness of these procedures was assessed by using a multiple probe across students design. Acquisition, maintenance, and generalization data were collected and analyzed. Results indicated that the simultaneous prompting procedure was effective in teaching 3 of the 5 students to follow a 16-step task analysis to wash their hands. All students who met criterion maintained and generalized the skills with 100% accuracy. All students acquired some of the instructive feedback stimuli. Future research issues are discussed.     

Activation of learned action sequences by auditory feedback

The present research addressed whether auditory feedback associated with a learned action sequence can activate the action representation of that sequence. Nonpianist participants learned to perform two melodies at a piano keyboard repeatedly during a trial. The participants heard feedback either from the melody they were performing (normal feedback) or from the other learned melody (termed alternate feedback). An additional tone functioned as an instruction cue to either switch melodies or continue the current melody. Following the instruction cues, participants typically paused just before switching, and paused similarly during trials with a continue cue. Participants paused longer after a continue cue when they experienced alternate rather than normal feedback. This effect was specific to instruction cues positioned at weak metrical accents—positions at which participants were less likely to switch overall. Feedback did not influence timing on switch trials. These findings indicate that influences of auditory feedback can activate learned action sequences, leading to longer latencies associated with cue evaluation.     

Interference of Sentence and Picture Contexts on Learning Prepositions

The effects of extra stimulus cues, such as pictures and sentences, on learning of preposition words were examined in two experiments. A one-way repeated-measures design was applied in the study. The results show that both sentences and pictures interfered with and blocked the learning of these context-dependent words in the simultaneous presentations. The superiority of feedback presentations over simultaneous presentations indicate that feedback techniques neutralize the blocking effect. More interestingly, however, the prepositions were learned more quickly in the absence of any context cues and this suggested that it is better to teach basic preposition words either by the presentation of them alone or if extra stimulus cues are to be used they should be presented as feedback.     

Assessing competencies of trainee sport psychologists: An examination of the ‘structured case presentation’ assessment method

ObjectivesThere is virtually no literature on how to assess competencies of applied sport psychologists. We assessed casework of applied sport psychology students and compared written case report assessment (WCRA) with structured case presentation assessment (SCPA) on reliability and acceptability (e.g., validity, transparency, feedback function and preference of methods, as perceived by students and assessors).DesignA quantitative, comparative study of two assessment methods.MethodParticipants were 11 students, nine supervisors and three exam committee members. A number of 18 cases were evaluated with both WCRA by the supervisor and SCPA by two exam committee members. Ten of these cases were also evaluated with WCRA by exam committee members. Interrater reliability measures were calculated and compared for the different assessment methods. Participants' perception of the validity, transparency, and feedback function of the methods, and the preferences for assessment methods were surveyed with a brief questionnaire.ResultsSCPA by the exam committee resulted in higher interrater reliability than WCRA by supervisor and exam committee. The feedback function of SCPA seemed superior to WCRA by either supervisor or exam committee. For assessment by the exam committee, the perceived validity and transparency of SCPA seemed higher than of WCRA. Students and exam committee had the highest preference for SCPA by supervisor and exam committee.ConclusionsOverall it can be concluded that, for assessment by the exam committee, structured case presentations provided a more reliable and acceptable method of assessment than written case reports only.     

Effects on Future Learning of Presenting Non-Target Stimuli in Antecedent and Consequent Conditions

This investigation assessed the effects of presenting non-target stimuli in the antecedent and consequent events on the future learning of responses to those stimuli. A 4-s constant time delay procedure was implemented to teach students with mild to moderate disabilities to read sight words. Future target stimuli (i.e., stimuli that were presented during instructional sessions of initial target stimuli, but were not directly instructed or targeted) were presented in one of two conditions; (a) in the antecedent event, or (b) in the consequent event portion of each instructional trial. Future target stimuli consisted of sight words that were unrelated to the target stimuli. An adapted alternating treatments design was used to assess and compare the two instructional conditions. Also, after students achieved criterion for reading target sight words, constant time delay was implemented to teach the future target stimuli. The number of sessions and the number and percentage of errors through criterion for teaching target and future target stimuli were assessed to measure the efficiency of the two conditions. All students reached criterion on the target stimuli and then acquired the future target stimuli when taught. Students required fewer sessions to achieve criterion on future target stimuli compared to initial target stimuli. There were minimal differences between the two conditions (i.e., antecedent versus consequent).     

Teaching Spelling of Social Studies Content Vocabulary Prior to Using the Vocabulary in Inclusive Learning Environments: An Examination of Constant Time Delay, Observational Learning, and Instructive Feedback

This study evaluated the effectiveness of using a 5 s constant time delay (CTD) procedure to teach the written spelling of social studies vocabulary words taken from the general education social studies content to students with mild disabilities. Subjects were 3 elementary students with mild disabilities. Instruction was delivered in a small group setting. Vocabulary words were different for each student, which allowed for observational learning by the other students in the group. Assessments of observational learning were conducted when each student attempted to spell their group-mate's words. Related instructive feedback (meaningful sentences containing the social studies vocabulary words) was presented in the consequent event of instructional trials. A multiple probe design across word sets was implemented to evaluate the effectiveness of the procedure. Results indicated that (a) CTD was reliably implemented and all students acquired the spelling of their own sets of 12 social studies vocabulary words with 100% accuracy and maintained this accuracy over time, (b) all students generalized their target spellings across settings and instructors, and (c) some observational and instructive feedback learning occurred for all students. Additionally, long-term maintenance of observational spellings decreased over time, and minor fluctuations in long-term maintenance of instructive feedback occurred.     

Learning to Time (Let) or Scalar Expectancy Theory (Set)? A Critical Test of Two Models of Timing

Two theories of timing, scalar expectancy theory (SET) and learning to time (LeT), make substantially different assumptions about what animals learn in temporal tasks. In a test of these assumptions, pigeons learned two discriminations: On Type 1 trials, they learned to choose a red key after a 1-s signal and a green key after a 4-s signal; on Type 2 trials, they learned to choose a blue key after a 4-s signal and a yellow key after a 16-s signal. Then, two psychometric functions were obtained by presenting them with intermediate durations (1 to 4 s and 4 to 16 s). The two functions did not superpose, and most bisection points were not at the geometric mean of the training stimuli (contra SET); for most birds, the function for Type 2 trials was to the left of the function for Type 1 trials (contra LeT). Finally, the birds were exposed to signals ranging from 1 to 16 s and given a choice between novel key combinations (e.g., red vs. blue). The results with the novel key combinations were always closer to LeT's than to SET's predictions. Observations of the birds' behavior also suggest that, more than being a mere expression of an internal clock, behavior constitutes the clock.
