Assessment of Repeated Relational Patterns for Individual Cases Using the SASB-Based Intrex Questionnaire

Repeated interpersonal patterns are central to case conceptualization and treatment planning in interpersonal and attachment-based approaches to therapy. In this study, raters (133 college students, 165 inpatients) provided data on the Intrex questionnaire (Benjamin, 2000 Benjamin, L. S. 2000. Intrex user's manual, Salt Lake City: University of Utah.  [Google Scholar]) about self-treatment, relationship with a significant other, and remembered interactions with parents in childhood. Within-subject profiles were inspected for precise behavioral matches conforming to 3 “copy process” (CP) patterns: identification (behaving like an important other), recapitulation (behaving as if the other person is still present and in charge), and introjection (treating the self the way another did). We observed CP evidence in most individual ratings. Consistent with expectation, nonclinical raters tended to copy a securely attached pattern of affiliation, low hostility, and moderate degrees of enmeshment and differentiation. Only patients copied maladaptive behavior at greater than base rate expectation. We discuss implications and provide recommendations for use of Intrex in individual assessment of CP.     

To a young basic scientist, about to embark on a program of translational research

From recent commentaries about the role of basic behavior scientists in translational research, I distill some advice to young investigators who seek to apply their basic science training to translational studies. Among the challenges are (a) devising use-inspired research programs that complement, and are not redundant with, existing efforts in basic and applied behavior analysis; and (b) making tactical decisions, such as the selection of methods and collaborators, based on the research topic rather than, necessarily, the existing traditions in behavioral research. Finally, it must be recognized that although use-inspired basic research has the potential to attract support to basic laboratories and contribute to "saving the world," neither of these outcomes is guaranteed. I discuss the relative risks for basic scientists who proceed with use-inspired basic research rather than ignore such translational questions.     

Translational research in behavior analysis: historical traditions and imperative for the future

"Pure basic" science can become detached from the natural world that it is supposed to explain. "Pure applied" work can become detached from fundamental processes that shape the world it is supposed to improve. Neither demands the intellectual support of a broad scholarly community or the material support of society. Translational research can do better by seeking innovation in theory or practice through the synthesis of basic and applied questions, literatures, and methods. Although translational thinking has always occurred in behavior analysis, progress often has been constrained by a functional separation of basic and applied communities. A review of translational traditions in behavior analysis suggests that innovation is most likely when individuals with basic and applied expertise collaborate. Such innovation may have to accelerate for behavior analysis to be taken seriously as a general-purpose science of behavior. We discuss the need for better coordination between the basic and applied sectors, and argue that such coordination compromises neither while benefiting both.     

TEACHING BRAIN—BEHAVIOR RELATIONS ECONOMICALLY WITH STIMULUS EQUIVALENCE TECHNOLOGY

Instructional interventions based on stimulus equivalence provide learners with the opportunity to acquire skills that are not directly taught, thereby improving the efficiency of instructional efforts. The present report describes a study in which equivalence‐based instruction was used to teach college students facts regarding brain anatomy and function. The instruction involved creating two classes of stimuli that students understood as being related. Because the two classes shared a common member, they spontaneously merged, thereby increasing the yield of emergent relations. Overall, students mastered more than twice as many facts as were explicitly taught, thus demonstrating the potential of equivalence‐based instruction to reduce the amount of student investment that is required to master advanced academic topics.     

Using stimulus equivalence technology to teach statistical inference in a group setting

Computerized lessons employing stimulus equivalence technology, used previously under laboratory conditions to teach inferential statistics concepts to college students, were employed in a group setting for the first time. Students showed the same directly taught and emergent learning gains as in laboratory studies. A brief paper-and-pencil examination, suitable for classroom use, captured effects demonstrated previously through laboratory tests. The results support the extension of the lessons to more naturalistic settings.     

AN UNEXPECTED EFFECT OF RECORDING FREQUENCY IN REACTIVE SELF-MONITORING

Two young competitive swimmers self-monitored their swimming using three different frequencies of recording. Contrary to the findings of previous studies, in which greater reactivity was associated with more frequent recording, swimming appeared to increase (compared to an instructions-only baseline) only with the least frequent of the recording schedules. The results highlight the importance of matching recording procedures to the performance of interest.     

The generalized matching law in elite sport competition: football play calling as operant choice

A mathematical model of operant choice, the generalized matching law was used to analyze play-calling data from the 2004 National Football League season. In all analyses, the relative ratio of passing to rushing plays was examined as a function of the relative ratio of reinforcement, defined as yards gained, from passing versus rushing. Different analyses focused on season-aggregate data for the league as a whole, game-by-game data for the league as a whole, and game-by-game data for individual teams. In all analyses except those for a few individual teams, the generalized matching law accounted for a majority of variance in play calling. The typical play-calling pattern reflected undermatching (suggesting imperfect sensitivity of play calling to yardage-gained reinforcers) and a bias for calling rushing plays. Bias was found to be a function of both the relative risk of turnovers and the relative variability in yards gained associated with passing versus rushing plays. The external validity of the matching analyses was supported by significant correlations between parameters of the generalized matching law and team success on offense and season winning percentage. These results illustrate the broad applicability of the generalized matching law to problems outside of the laboratory.     

Verbal self-reports of emergent relations in a stimulus equivalence procedure.

During a preliminary training phase, college students were taught to categorize each of their responses accurately in a conditional discrimination task as either correct or incorrect. Next, in the absence of self-reports, subjects acquired conditional discriminations (involving novel stimuli) prerequisite to the formation of two four-member equivalence classes. The self-report procedure was reinstated during probe sessions that tested for untrained relations indicative of equivalence class formation. Interspersed trials involving trained relations provided a positive control, and trials with no class-consistent comparison provided a negative control. Eight of 10 subjects demonstrated equivalence class formation; all accurately reported their performance on trained relations and on trials with no class-consistent comparison. Subjects also reported their performance on most untrained (emergent) relations accurately, but in several instances self-reports indicated failure or uncertainty despite nearly perfect emergent-relations performance. These inconsistencies add to a growing body of literature that suggests there are differences between individual types of emergent relations. We suggest that the present procedure may be helpful in understanding these differences and other equivalence-related effects.     

Discriminative stimulus effects of diazepam and buspirone in normal volunteers.

A within-subject design was used to characterize the effects of dose manipulations on discriminative and self-reported effects of oral diazepam and buspirone. Subjects were trained to discriminate diazepam (10 mg) versus placebo (n = 10), or buspirone (10 or 15 mg) versus placebo (n = 9). The compounds were identified to subjects by letter code before discrimination training began. In later sessions, correct identifications at 2 hr after the oral administration of drug earned money. All subjects showed accurate discrimination performance during the test-of-acquisition phase. In a low-dose generalization phase, diazepam and buspirone produced dose-related increases in drug identifications across a four-fold range of doses. In a subsequent low-dose training phase, in which subjects were trained to discriminate progressively lower drug doses, the median lowest discriminable dose of diazepam and buspirone was 2.5 and 7.5 mg, respectively. Dose-response functions for drug identifications were shifted leftward in the low-dose training phase relative to the low-dose generalization phase, suggesting that reinforcement of progressively lower doses enhances drug discriminability. The self-reported effects of diazepam and buspirone were similar (e.g., both drugs increased ratings of drug strength and clumsy/uncoordinated) and different (e.g., diazepam but not buspirone increased ratings of drowsy/sleepy; buspirone but not diazepam increased ratings of tense/nervous). This study demonstrates discriminative and self-reported effects of diazepam and buspirone at doses lower than previously shown to be behaviorally active, and suggests that at commonly used clinical doses, diazepam is relatively more discriminable than buspirone.
