Some verbal behavior about verbal behavior

Beginning with behavior analysts' tendency to characterize verbal behavior as "mere" verbal behavior, the author reviews his own attempt to employ it to influence both his staff and policies of our government. He then describes its role in psychopathology, its effect on speakers in healing themselves and on engendering creativity. The paper ends by calling to our attention the role of verbal behavior in the construction of behavior analysis.     

Positive behavior support and applied behavior analysis

This article reviews the origins and characteristics of the positive behavior support (PBS) movement and examines those features in the context of the field of applied behavior analysis (ABA). We raise a number of concerns about PBS as an approach to delivery of behavioral services and its impact on how ABA is viewed by those in human services. We also consider the features of PBS that have facilitated its broad dissemination and how ABA might benefit from emulating certain practices of the PBS movement.     

Pack behavior

We analyze a sequential decision model, where every decision maker has her own preferences over actions. Some actions have positive Externalities if a large enough population has previously chosen them, and those Externalities may lead a decision-maker to ignore her own preferred actions to benefit from those Externalities. We give a fairly general sufficient condition such that, on almost every equilibrium path, every decision maker eventually prefers to benefit from group Externalities. We show that this situation, called pack behavior, is observationally equivalent to a herd behavior, but it is triggered by positive Externalities generated by group decision, instead of standard belief-based decisions. We also show that this notion is not ex-ante Pareto-efficient in general.     

Verbal behavior

The recent history and current status of the area of verbal behavior are considered in terms of three major thematic lines: the operant conditioning of adult verbal behavior, learning to be an effective speaker and listener, and developments directly related to Skinner's Verbal Behavior. Other topics not directly related to the main themes are also considered: the work of Kurt Salzinger, ape-language research, and human operant research related to rule-governed behavior.     

Emergency behavior

There is a class of actions — reflex actions — which seem not to spring from any intention, but for which we nevertheless wish to take responsibility. It is suggested that these actions are appropriately said to be done intentionally, in spite of our never having an intention to do them. And this grammatical anomaly indicates that the behavior in question requires a special kind of account; one which might be characterized as derivative: parasitic on the more paradigmatic sort of action explanation.     

Pedophilic-voyeuristic behavior

It is reported on a 26 year-old man with a paedophilic-voyeuristic behavior in the frame of a sexual abnormal development on the basis of a primary sexual pathological personality structure (Szewczyk). The maldevelopment has be expressed monosymptomaticly in the sphere of sexuality.     

Imitative behavior

This article reviews the results of experimental studies on imitative behavior reported by various investigators, and then discusses the possible brain mechanisms responsible for this behavior. It was found that human infants in their first hours of life were already capable of spontaneous imitation of simple motor acts demonstrated by an adult, without previous training or reward; these observations suggest that imitative behavior is an innate process that can be considered anunconditional reflex of imitation. It was also found that satiated animals resumed eating when they saw their companions eating. In the latter case, the imitative reflex triggered the previously acquired feeding behavior. Similar mechanisms could be responsible for the phenomenon of eating more in the presence of companions than in their absence, as well as that of preferring the food chosen by companions. When followed by a reward, the imitative act can be learned—that is, transformed into aninstrumental conditional response; learning by imitation of simple motor acts was observed in animals, and that of complex motor acts was observed in children who had already achieved a certain developmental stage. In animals, learning complex motor tasks was facilitated by previous observation of a companion performing this task. In this case, the presence of the observer during the session could lead to habituation of the experimental situation and production of associations between this situation and stimuli or emotions related to the reward or punishment, and might result in more efficient learning later. The imitative behavior can be inhibited by stimuli producing responses antagonistic to the act of imitation.     

Maternal sensitivity behavior and infant behavior in early interaction

Maternal sensitivity behavior and infant behavior in early interaction were investigated among 57 Finnish mother–child pairs. Their interaction was video‐recorded at home in free‐play situation when the infants were 3 months and 12 months of age, and evaluated using the Parent–Child Early Relational Assessment Scale (PCERA). Maternal sensitivity behavior was mainly related to infant's positive aspects of mood, social and play behavior, and visual contact, both at 3 months and 12 months of age. Even though maternal sensitivity behavior correlated to infant behavior at 3 months and 12 months, infant behavior at 3 months of age contributed to later maternal sensitivity behavior. ©2001 Michigan Association for Infant Mental Health.     

The local organization of behavior: dissociations between a pigeon's behavior and self-reports of that behavior

The purpose of the experiment was to study the relation between what an organism does in a setting that demands temporal patterning of behavior and what it reports it has done. More specifically, a pigeon produced two classes, shorter and longer, of temporal patterns of key pecks (interresponse times) on a center key. Occasionally, a symbolic matching-to-sample probe arranged on side keys asked the pigeon whether its most recent pattern was a shorter or longer one. The longer reinforced pattern was always three times as long as the shorter one and the two patterns were reinforced equally often. Absolute duration of reinforced patterns was varied. In some conditions, interresponse-time distributions on the center key were bimodal, indicating a clear behavioral adaptation to the contingency, yet a bird did not report very well by appropriate side-key responding what its most recent interresponse time had been. In other conditions, the interresponse-time distributions were less clearly bimodal, yet a bird reported more accurately its previous interresponse time as shorter or longer. Thus, there was a dissociation between how well behavior on the center key conformed to the schedule requirement and how well a bird reported what it was doing on the center key. In addition, as absolute duration of the reinforced patterns was increased, a bird categorized its most recent pattern less well even as its preference for the shorter pattern increased dramatically. These results were interpreted as an example of the phenomenon of dissociation between tacit knowledge and knowledge.     

Effect of the good behavior game on disruptive library behavior

A modification of the good behavior game was used to reduce disruptive behaviors during a weekly library period of children in a fourth-grade class. Modifications included student input in designing rules, attempts to state rules in positive terms, observation of class behavior in the experimental (library) setting as well as in a comparison (classroom) setting, and librarian involvement in instituting the game coupled with teacher involvement in delivering reinforcers. Reinforcers consisted of special classroom activities conducted by the teacher with winning team members. Modification of the good behavior game did not detract from its effectiveness in reducing disruptive and off-task behavior.
