The role of intraverbal bidirectional naming in the establishment of comparative relations.

The purpose of the current study was to extend the research on the possible role of verbal mediation in the establishment of comparative relations. We conducted four experiments in which 14 participants received conditional discrimination training with nonarbitrary and arbitrary stimuli, followed by derived comparative and transformation of function tests. Participants learned to select the smallest or biggest comparison across multiple exemplars in the presence of abstract samples.

Correspondence Between Vocal-Verbal Behavior and Go/No-Go Responses During the Successive Matching-to-Sample Procedure.

In the current study, eight college students were exposed to a successive matching-to-sample (S-MTS) procedure utilizing non-verbal auditory stimuli consisting of common sounds. During emergent relations tests, participants were asked to talk aloud, and their vocal-verbal statements were transcribed and categorized as class-consistent, class-inconsistent, or irrelevant. All participants met emergence criterion for symmetry and four did so for transitivity/equivalence.

A further investigation regarding the efficacy of and preference for positive and corrective feedback.

Although feedback is a widely used intervention for improving performance, it is unclear what characteristics individuals prefer and what is necessary for it to be effective. The purpose of this study was to systematically extend Simonian and Brand (2022) by addressing the limitations of the study and adding a best-treatment phase. During an acquisition phase, participants received either positive, corrective, or no feedback upon task completion.

A Treatment Evaluation of Successive and Simultaneous Visual Stimulus Presentation During Tact Training with Children with Autism.

The purpose of this study was to assess whether variations in visual stimulus presentation during tact training would affect efficacy, efficiency, and the emergence of listener responses. Participants included two preschool-aged children diagnosed with autism. We implemented two teaching conditions using an adapted alternating treatment design with intrasubject replications.

Procedural parameters in equivalence-based instruction with individuals diagnosed with autism: A call for systematic research.

Equivalence-based instruction (EBI) is an efficient and efficacious methodology to establish equivalence classes that has been used to teach various academic skills to neurotypical adults. Although previous reviews confirmed the utility of EBI with participants with developmental disabilities, it is unclear whether certain procedural parameters are associated with positive equivalence outcomes. We extended previous reviews by categorizing studies that used EBI with individuals diagnosed with autism spectrum disorder and assessed whether any procedural parameters were associated with better equivalence responding.

A parametric analysis of procedural fidelity errors following mastery of a task: A translational study.

Procedural fidelity is defined as the extent to which the independent variable is implemented as prescribed. Research using computerized tasks has shown that fidelity errors involving consequences for behavior can hinder skill acquisition. However, studies examining the effects of these errors once skills have been mastered are lacking.

The effects of note taking as a visual mediation strategy on the formation of equivalence classes.

A graphic organizer (GO) is a note-taking device with concepts and fill-in spaces that may enhance equivalence yields under suboptimal training and testing parameters (e.g., linear training, simultaneous testing, five-member all-abstract classes).

A translational evaluation of component skills for the establishment of multiply controlled intraverbals.

Intraverbal behavior is a type of verbal behavior in which the response form has no point-to-point correspondence with its verbal stimulus. However, the form and occurrence of most intraverbals is under the control of multiple variables. Establishing this form of multiple control may depend on a variety of preestablished skills.

Audience Control over Children's Honest Reports.

We evaluated audience control over children's honest reports using a reversal (ABA or ABAB) design. Four typically developing children performed a computer game in which they had to shoot a target and then report on their performance during and at the end of each session. Baseline assessed the accuracy of their reports in the absence of an experimenter.

The Use of the Go/No-Go Successive Matching-to-Sample Procedure with Nonverbal Auditory Stimuli to Establish Equivalence Classes and Speaker Behavior.

The purpose of the current study was to extend the findings on the use of the go/no-go successive matching-to-sample (S-MTS) procedure to establish auditory equivalence classes. Eight college students learned to conditionally relate nonverbal auditory stimuli into three, 3-member classes. Following training, all participants met the emergence criterion for symmetry, and six out of eight participants met the emergence criterion for transitivity/equivalence.

Establishing derived reinforcers via stimulus equivalence.

If one of several stimuli in an equivalence class acquires a function, it transfers to all members of the respective class. Even though research has demonstrated this transfer across a variety of stimulus functions (e.g.

Jack and Me.

Although Jack Michael has greatly influenced the field of behavior analysis, very few have had the opportunity to be directly supervised by him. In this article, I share my personal history as one of Jack's last graduate students to illustrate his teaching and mentorship approach. Jack was a caring advisor who has had a long-lasting impact on both my personal life and my professional career.

Teaching a small foreign language vocabulary to children using tact and listener instruction with a prompt delay.

This study consisted of a systematic replication of previous research examining the effects of tact and listener instruction on the emergence of native-to-foreign (NF) and foreign-to-native (FN) intraverbals in children who had experienced difficulties learning to read and write. We assigned different sets of stimuli to tact and listener conditions, and taught 4 children to tact or respond as listeners in a foreign language using a progressive prompt delay with differential reinforcement. All participants mastered tacts and listener responses in the foreign language.

Teaching Children with Autism to Mand for Information Using "Why?" as a Function of Denied Access.

The current study evaluated a procedure used to teach two children with autism to ask "why" questions maintained by causal information about an event. To increase the value of information as a reinforcer, the experimenter denied access to preferred items and did not provide a reason for the denial. Participants were taught to ask "why" questions and were provided with information that led them to access preferred items.

The establishment of auditory equivalence classes with a go/no-go successive matching-to-sample procedure.

The go/no-go successive matching-to-sample (S-MTS) procedure involves the presentation of a sample followed by one comparison in the same location. Participants are required to either touch (go) or refrain from touching (no-go) related and unrelated comparisons, respectively. One advantage of S-MTS is that both sample and comparisons can be auditory.

Establishing equivalence-equivalence analogical relations via tact and listener training.

We investigated the role of verbal behavior on the emergence of analogy-type responding as measured via equivalence-equivalence relations. In Experiment 1, 8 college students learned to label arbitrary stimuli as, "vek," "zog," and "paf", and in Experiment 2, 8 additional participants learned to select these stimuli when hearing their names in an auditory-visual matching-to-sample (MTS) task. Experimenters tested for the emergence of relational tacts (i.

The establishment of auditory-visual equivalence classes with a go/no-go successive matching-to-sample procedure.

The current study evaluated the effectiveness of a go/no-go successive matching-to-sample procedure (S-MTS) to establish auditory-visual equivalence classes with college students. A sample and a comparison were presented, one at a time, in the same location. During training, after an auditory stimulus was presented, a green box appeared in the center of the screen for participants to touch to produce the comparison.

The influence of correlations between noncritical features and reinforcement on stimulus generalization.

One strategy to program for generalization is to vary noncritical features in teaching exemplars, thereby avoiding noncritical features from being highly correlated with reinforcement and thus gaining faulty stimulus control. In the current translational evaluation, 2 groups of adults of typical development were taught to respond to arbitrary stimuli with experimenter-defined critical and noncritical features in a matching-to-sample task. The teaching arrangement used for 1 group programmed for low correlation between noncritical features and reinforcement; the teaching arrangement used for the other group programmed for high correlation between noncritical features and reinforcement.

An evaluation of matrix training to teach college students piano notes and rhythms.

Twelve college students learned to tact the names of notes and rhythms and play them when presented with compound stimuli (visuals of notes and rhythms on a musical staff). In Experiment 1, we assessed generalization by presenting novel notes, rhythms, and compound stimuli not previously paired together. In the second experiment, we added a metronome that played at 60 beats per minute in all conditions for 3 out of 6 participants to ensure consistent tempo.

Using multiple-tact training to produce emergent visual categorization in children with autism.

Previous research has shown that children with autism spectrum disorder (ASD) can categorize visual stimuli without direct training when they can also tact these stimuli using a common name and behave as listeners in relation to this name. However, children usually learn to assign objects specific names prior to learning the category to which they belong. The current study replicated previous research and evaluated whether multiple-tact training would establish visual categorization (measured by a picture sorting test) and listener behavior.

The role of verbal behavior in the establishment of comparative relations.

Twelve college students received conditional discrimination training with nonarbitrary and arbitrary stimuli, and derived comparative and transformation of function tests with a think-aloud condition across 2 experiments. Participants who failed these tests received remedial verbal operant training. Four control participants received verbal operant training alone.

The effects of listener training on the development of analogical reasoning.

We evaluated the effects of listener training on the emergence of analogical reasoning, as measured via equivalence-equivalence and explored the role of verbal behavior when solving analogy-type tasks. We taught 18 college students to select component stimuli from 2 classes, labeled "vek" and "zog," and evaluated tacts and relational responding in the presence of baseline (AB and BC), symmetry (BA and CB), and transitivity (AC and CA) compounds. In Experiment 1, 5 out of 6 participants passed analogy tests, but none of them engaged in the relational tacts "same" and "different" during tact tests, possibly due to lack of instructional control.

A comparison of response interruption and redirection and competing items on vocal stereotypy and appropriate vocalizations.

The current study compared the reductive effects of response interruption and redirection (RIRD) and competing items (including sound-producing and nonsound-producing toys) on the vocal stereotypy exhibited by two children diagnosed with Autism Spectrum Disorder. Sound-producing toys reduced vocal stereotypy relative to nonsound-producing toys and RIRD reduced stereotypy and increased rates of appropriate vocalizations to a greater extent than providing competing items. These findings replicate and extend previous literature suggesting that RIRD and sound-producing competing items are effective methods to treat vocal stereotypy.

Exposure to a specific prompt topography predicts its relative efficiency when teaching intraverbal behavior to children with autism spectrum disorder.

Comparisons of the relative efficiency of different prompt topographies (visual or auditory), when teaching intraverbal behavior to children with disabilities, have yielded idiosyncratic results. Recent research has shown that previous exposure to a specific prompt type may affect its efficiency when teaching intraverbal behavior to preschool children. The current study was an attempt to replicate these results with 3 children diagnosed with autism spectrum disorder.
