Measuring and reducing college students' procrastination

We examined college students' procrastination when studying for weekly in-class quizzes. Two schedules of online practice quiz delivery were compared using a multiple baseline design. When online study material was made available noncontingently, students usually procrastinated. When access to additional study material was contingent on completing previous study material, studying was more evenly distributed. Overall, the mean gain in percentage correct scores on weekly in-class quizzes relative to pretests was greater during contingent access than during noncontingent access conditions.     

Let’s Play: Using Systemic and Experiential Techniques in the Play Therapy Instruction of MFT Masters’ Students

Marriage and family therapists are uniquely poised to work with entire families, including children. It is surprising then, that so few MFTs affiliate with play therapy. Many COAMFTE accredited masters’ programs offer some form of play therapy training, but therapists often report feeling uncomfortable with play therapy (Gil, 2015). In this paper, we offer a condensed refresher course on play therapy for MFTs, including suggested readings, materials, and instructions to expand training from a 2-day seminar to a 14-week course. We discuss the strengths and weaknesses of offering play therapy instruction as a semester long required course for masters’ students.     

An evaluation of textual prompts and generalized textual instruction‐following

The benefit of permanent prompts depends on the extent to which their use is generalized. Previous research has demonstrated both control by and efficacy of pictorial prompts (e.g., Phillips & Vollmer, 2012). The present studies similarly evaluated stimulus control by textual prompts. Six school aged children with intellectual disabilities were taught to complete four 5‐step instructional sets under the control of textual prompts. All 6 subjects showed some generalization to the final set. The results suggest that training served 1 of 3 purposes: (a) established control by the textual prompts or the ordinal sequence thereof, (b) addressed a reading deficit, or (c) addressed the lack of a motivating operation during baseline. Training a single task sequence may not be sufficient for acquisition of generalized textual instruction‐following. However, establishing appropriate stimulus control by the textual prompts may facilitate acquisition of a generalized repertoire.     

Altering the timing of academic prompts to treat destructive behavior maintained by escape

Following a functional analysis showing that destructive behavior was reinforced by escape, we altered the aversiveness of task demands by interspersing easy and difficult tasks and by presenting a corrective prompt as an antecedent event the next time a previously failed item was presented; this procedure was compared with one in which the corrective prompt was provided as an immediate consequence. Results of a reversal design showed that the antecedent prompt acted as an establishing operation and reduced destructive behavior to zero.     

Gross-motor skill acquisition by preschool dance students under self-instruction procedures

The effects of two training procedures--(a) modeling and praise and (b) self-instruction, modeling, and praise--on complex gross-motor chain acquisition for preschool dance class students were evaluated. Six girls participated in the study. A multiple baseline design across six gross-motor chains with a secondary group comparison for treatment order effects was used. Both procedures were effective in teaching the gross-motor chains. Nevertheless, for 4 of the 6 participants, the self-instruction procedure produced a faster acquisition rate in at least two of the three comparable pairs of gross-motor chains. Furthermore, very early in gross-motor chain acquisition, for five of the six gross-motor chains, the self-instruction condition was associated with faster response acquisition.     

Using stimulus equivalence‐based instruction to teach young children their caregivers' contact information

Stimulus equivalence‐based instruction (EBI) was used to teach young children of typical development three 4‐member equivalence classes containing contact information from three caregivers (e.g., mother, father, and grandmother). Each class comprised the caregiver's (a) photograph, (b) printed name, (c) printed phone number, and (d) printed name of employer. A pretest‐train‐posttest‐maintenance design with a nontreatment control group comparison was used. Pretests and posttests assessed the degree to which class‐consistent responding occurred across both visual–visual matching tasks and intraverbals. Intraverbal responding was also probed with a novel instructor. Overall, EBI participants scored significantly higher during the posttests than the control participants across both the derived relations and intraverbal tests. These differences maintained 2 weeks later. Thus, responding generalized to (a) a different topography (i.e., intraverbal), (b) auditory versions of the stimuli, and (c) in the presence of a novel instructor. How such procedures may benefit lost children are discussed.     

Expansion of Sidman's theory: The inclusion of prompt stimuli in equivalence classes

Stimulus equivalence is defined as the ability to relate stimuli in novel ways after training in which not all of the stimuli had been directly linked to one another. Sidman (2000) suggested all elements of conditional discrimination training contingencies that result in equivalence potentially become class members. Research has demonstrated the inclusion of samples, comparisons, responses, and reinforcers in equivalence classes. Given the evidence that all elements of a conditional discrimination become part of the class, the purpose of this study was to determine if class-specific prompts would also enter into their relevant equivalence classes. Experiment 1 investigated the inclusion of prompts in an equivalence class using abstract stimuli with neurotypical students enrolled in higher education courses. Experiment 2 systematically replicated Experiment 1 using meaningful stimuli and individuals diagnosed with autism spectrum disorder. The results of both experiments demonstrated that class-specific prompts became part of equivalence classes with the other positive elements of the contingency. The results are discussed in terms of class expansion and the potential impact on equivalence-based instruction.     

‘It’s OK to feel totally confused’: reflection without practice by preservice teachers in an introductory education course

In the following article, we describe our research with preservice teachers (PSTs) engaged in an introductory course in curriculum, instruction, and technology. Typically, efforts to engage PSTs in reflection focus on the student-teaching experience. We assert there is potential for PSTs to think deeply about their identities prior to actual classroom experience. Our research concerns the development of reflective pedagogical thinking by PSTs, stimulated by a variety of curricular, instructional, and technological learning experiences. We will highlight the pedagogical innovations we employed to stimulate PSTs to engage in meaningful reflection prior to their student-teaching experiences. We will describe our learning experiences and nontraditional grading scheme in the course, and examine the impact of those practices on PST reflective writing.     

Preference assessment training via self‐instruction: A replication and extension

We examined the effects of a self‐instructional and feedback package on participants’ implementation of a paired‐stimulus preference assessment. Specifically, in Experiment 1, we used a multiple baseline design across participants to replicate and extend the results of Graff and Karsten (2012) by evaluating the effectiveness of their self‐instructional manual. A majority of the participants (i.e., 5 of 7 undergraduate students and 4 of 5 in‐home behavior technicians) achieved mastery with the self‐instructional package. The remaining participants met the mastery criterion after brief modeling and feedback sessions. In Experiment 2, we identified the most effective component of the feedback condition from Experiment 1 when a self‐instructional package was not sufficient. Brief feedback sessions in which participants received a list of the targeted responses plus information regarding accuracy of emitted responses was sufficient for 5 of 6 participants to achieve mastery.
