Behaviorism, private events, and the molar view of behavior

Viewing the science of behavior (behavior analysis) to be a natural science, radical behaviorism rejects any form of dualism, including subjective-objective or inner-outer dualism. Yet radical behaviorists often claim that treating private events as covert behavior and internal stimuli is necessary and important to behavior analysis. To the contrary, this paper argues that, compared with the rejection of dualism, private events constitute a trivial idea and are irrelevant to accounts of behavior. Viewed in the framework of evolutionary theory or for any practical purpose, behavior is commerce with the environment. By its very nature, behavior is extended in time. The temptation to posit private events arises when an activity is viewed in too small a time frame, obscuring what the activity does. When activities are viewed in an appropriately extended time frame, private events become irrelevant to the account. This insight provides the answer to many philosophical questions about thinking, sensing, and feeling. Confusion about private events arises in large part from failure to appreciate fully the radical implications of replacing mentalistic ideas about language with the concept of verbal behavior. Like other operant behavior, verbal behavior involves no agent and no hidden causes; like all natural events, it is caused by other natural events. In a science of behavior grounded in evolutionary theory, the same set of principles applies to verbal and nonverbal behavior and to human and nonhuman organisms.     

Quantifying private events: A functional measurement analysis of equisection

Functional measurement theory was applied to bisection, trisection, and quadrisection of grayness. Theoretically, these judgments should obey an averaging model. But the overt responses are not a valid measure of subjective magnitude (since they are made on the physical stimulus continuum), and so they cannot be used directly to test the model. However, scaling and model testing can both be accomplished simultaneously using functional measurement theory. If the subject is indeed averaging, then there exists a monotone transformation that makes the data additive; and this transformation can be computed with FUNPOT, Weiss’s (1973a) computer program which finds polynomial transformations that reduce selected effects. Further, determination of this transformation also reveals the psychophysical function, because it gives the relation between subjective magnitude and overt response. For bisection, the averaging model was successful; it was possible to find a monotone transformation that made the data additive. This psychophysical function differed somewhat in form from the Munsell scale. It gained cross-task validity from its agreement with a grayness scale obtained from rating data (Weiss, 1972). For trisection and quadrisection, the averaging model was not accepted; it was not possible consistently to find transformations which induced additivity.     

Stimuli, reinforcers, and private events

Radical behaviorism considers private events to be a part of ongoing observable behavior and to share the properties of public events. Although private events cannot be measured directly, their roles in overt action can be inferred from mathematical models that relate private responses to external stimuli and reinforcers according to the same quantitative relations that characterize public operant behavior. This approach is illustrated by a model of attending to stimuli and to anticipated reinforcers in delayed matching to sample, in which the probabilities of attending are related to reinforcer rates by an expression derived from research on behavioral momentum.     

Empathy and evaluation: Understanding the private meanings of behavior

This paper makes three points. First, empathy cannot be considered an epistemic basis for qualitative research and evaluation. Second, it is, however, a valuable method for understanding the private meanings of words and deeds. Third, this method is not completely reliable for purposes of what Popper called refutation, but is useful in what he dubbed scientific conjecture or the generation of theory. Basic researchers will need to take the necessary steps to subject empathetic hunches to critical examination. However, owing to the exigencies of action settings and decision-making, disciplined conjectures are sometimes the most that evaluators can hope to record.An earlier version of this paper was printed in the Proceedings of the Far Western Philosophy of Education Society, 1989.

Measuring the flashbulb-like nature of memories for private events: the flashbulb memory checklist

What do we remember following an emotionally charged event? The assessment of memory characteristics for an emotional event represents one of the most challenging issues in the domain of autobiographical memory. Literature of flashbulb memories (FBMs) provides a crucial contribution on this issue: Following an emotional and unexpected public event, people remember not only central details of the episode, but also irrelevant, peripheral and idiosyncratic details of the reception context in which they learned of the news. The present study was set up to assess the factorial structure (samples 1 and 2) and convergent validity (sample 2) of an FBM checklist, an instrument designed to measure Flashbulb-like features of memories for emotional private events. Factorial analyses account for an oblique two-factor solution – FBM Specificity and Confidence – while correlational analyses support the convergent validity of this instrument. Practical implications are discussed, especially for the credibility assessment of witnesses of emotional events in forensic settings.     

Snapshots from therapy: Exploring operationalisations and ways of studying flashbulb memories for private events

A total of 13 clients (10 women and 3 men, mean age 32.85 years, SD 10.50) were interviewed after finishing group therapy, and 7 were re-interviewed 4-5 months later. The clients recounted all the specific episodes they remembered from the therapy. The memories were classified as flashbulb memories or non-flashbulb memories according to two different criteria: consistency and phenomenological clarity. Clients had flashbulb memories from therapy according to both operationalisations. Flashbulb memories according to a phenomenology-based operationalisation referred to more unusual episodes and more often to episodes associated with insight than non-flashbulb memories. The consistency operationalisation did not differentiate between flashbulb and non-flashbulb memories with respect to characteristics of the remembered events. Number of remembered episodes was positively related to the subjective evaluation of the therapy.

Measurement of nontargeted problem behavior during investigations of resurgence

Resurgence occurs when a previously extinguished behavior reemerges once a more recently reinforced behavior is placed on extinction. Previous research has suggested that nontargeted responses within the same response class recur alongside target-response resurgence (e.g., da Silva, Maxwell, & Lattal, 2008; Lieving, Hagopian, Long, & O'Connor, 2004). The purpose of this two-experiment investigation was to examine target response resurgence while simultaneously measuring the occurrence of nontargeted responses. Three children diagnosed with autism spectrum disorder who displayed multiple topographies of problem behavior participated. In Experiment 1, a three-phase resurgence procedure was conducted and all three participants displayed target-response resurgence accompanied by the emergence of nontargeted forms of problem behavior. These findings were replicated in Experiment 2 using a 30-min assessment procedure. The implications of these findings as they pertain to the treatment of severe problem behavior and utility of a brief relapse assessment are discussed.

Teaching children with autism to tact private events based on public accompaniments

We evaluated a method for teaching children with autism spectrum disorder to respond to tactile stimulation of multiple body parts. Various objects (e.g., hairbrush) produced the sensations (e.g., prickly). In a multiple baseline design across participants, participants learned 9 sensation body part tacts and the evaluation concluded with tests of generalization to 3 novel body parts, 6 novel objects, and 3 novel sensations. Participants demonstrated generalization to novel objects, and to a lesser extent, novel body parts, but did not generalize tacts to novel sensations. These findings are discussed in terms of implications for teaching children with autism to tact sensations.     

The sexual attitudes and behavior of private and public school students: a comparative study

This study reports the results of a questionnaire and interview-based study designed to test the often-stated claims of college preparatory schools, i.e., "prep schools" that, along with a high-quality education, they also instill a superior system of values than is possible in a public school. Comparisons are made between "preppies" and college-bound public school students in terms of sexual attitudes and behavior as well as with the earlier studies of Kinsey, Pomeroy et al., Sorensen, and Haas. The results indicate that, even when measured by the standards of the schools themselves, preppies rank lower in many areas, especially attitudinal, than their public school counterparts. Despite the enormous amount of faculty energy expended to prevent it, the sexual activity of the prep school student, both in amount and degree of sophistication, is significantly greater than is found in public school students. Further, in terms of sex-related drug use, exploitiveness, female self-image, homophobia and sexism, preppies do not compare favorably with public school students. Hypotheses are advanced to account for the differences detected and suggestions made for future research. It is also suggested that the research technique used in this study has great potential for future study of adolescent sexual attitudes and behavior that, in the past, have been extremely difficult to perform.     

Quasi-statistical inference in rating behavior I. Preliminary investigations

Bem and Allen (1974) have suggested that trait consistency-ratings can function as a moderator variable, with regard to the cross-situational validity of trait position-ratings. The present study attempts to consider the relationship between these two types of self-ratings. A model of “man the quasi-statistician” was proposed which yields the predictions that (a) consistency-ratings will vary positively with the polarization-estimate from position-ratings and (b) the extent of correlation will be a function of the degree of polarization associated with a given class of trait.In two experiments, position-ratings and consistency-ratings were obtained over a series of dimensions. The predictions were confirmed in both studies. In addition, Experiment II provided evidence for a correspondence between intuitive and formal estimates of central tendency polarization, although this was not the case for dispersion. The results were discussed as bearing on the model and as relating to the findings of Bem and Allen (1974).
