On the nature and order of organizational processing: A reply to Peterson

Several points in the original article by Palmer and Rock (1994) are clarified in light of Peterson’s (1994) commentary. First, we address several issues related to the nature and order of organizational processes in our theory. We argue that many of her objections result from misconceptions about our theory. We attempt to clarify the relevant issues, including the fact that we intended the theory to describe an ordering of processes in cascade rather than as a sequence of classical discrete stages. Second, we discuss Peterson’s objections to our discussion of her findings on the relation between figure-ground processing and object recognition. We argue against her “prefigural recognition” proposal on logical grounds and provide an alternative account of her findings in terms of our theory.     

Assessment of role-play generalization across qualitatively different situations

Role-play generalization of newly acquired assertive behavior was assessed across different response situations in a clinical outpatient sample. Prior to assertive training, subjects completed two paper-and-pencil inventories and a series of role-play situations. Behavioral role-play scenes included four response forms: making requests, expressing affection, standing up for rights, and expressing displeasure. Subjects were randomly assigned to treatment or test-retest conditions and the treatment subjects received six 2-hr sessions of assertion training using modeling, behavior rehearsal, instruction, positive reinforcement, assignedin vivo homework, bibliotherapy, and daily recordings of assertive behavior. Posttreatment, subjects completed the paper-and-pencil measures, trained role-play scenes, and a set of dissimilar untrained scenes requiring different response forms (giving compliments, receiving compliments; refusing unreasonable requests and expressing justified anger). Videotapes were rated blindly and in random order at the conclusion of the study by trained judges. Treatment and test-retest subjects were equivalent prior to training. Posttreatment for the two groups differed in self-report, role-play behavior in trained situations, and role-play behavior in untrained dissimilar situations (allp<.001). MANOVA with repeated measures confirmed that trained and generalization role-play scenes were quantitatively, as well as qualitatively, different, confirmed that treatment and test-retest subjects exhibited different performance levels posttreatment on both trained and generalization scenes, and revealed four significant interactions (allp<.001). Implications of the interactions are discussed. Canonical correlation revealed that subjects displayed significant commonality in their behavioral profiles across different response forms. The findings indicate that complex training resulted in generalization from trained situations to untrained and dissimilar generalization scenes for the clinical outpatient sample.     

Essentialism and selectionism in cognitive science and behavior analysis.

Contingencies of selection, be they phylogenetic or ontogenetic, merely set boundaries on units; they do not provide blueprints. Thus, variability is fundamental to all products of selection. Skinner, by characterizing the units of analysis in behavior as generic in nature, established his science squarely within the selectionist paradigm, thereby avoiding the tendency, common throughout psychology, to slip into essentialist analyses. The distinction between essentialism and selectionism is refined in this article, and prominent examples of essentialism in linguistics, theories of memory, theories of representation, associationism, and even in behavior analysis are identified. Recent trends in cognitive science--specifically, research on adaptive networks--is amenable to a selectionist interpretation, suggesting the possibility of future fruitful interactions with behavior analysis.     

WHEN TO BEAR FALSE WITNESS: AN EVOLUTIONARY APPROACH TO THE SOCIAL CONTEXT OF HONESTY AND DECEIT AMONG COMMERCIAL FISHERS

Abstract. This paper uses an evolutionary perspective to identify variables influencing compliance with moral codes about honest communication. Data on over one thousand radio conversations among lobster fishers in two harbors in Maine are compared in regard to the sharing of information. The sharing of accurate information is found to be significantly more frequent in the harbor that is more integrated by reciprocally altruistic relationships. This is consistent with the view that moral systems are systems of indirect reciprocity, but it also suggests that humans have evolved to base their compliance with moral codes on cues from their social environment.     

Follow-up survey of pregnancies with diagnoses of chromosomal abnormality

A small clinical survey was undertaken at East Carolina University School of Medicine to examine the factors which influenced the decisions of five families to continue pregnancies after a chromosomal abnormality was detected. Little has been published concerning the psychosocial effects after continuing pregnancies in which the fetus was diagnosed with a chromosome abnormality by amniocentesis. In order to identify the factors that influenced their decisions, an interview with each couple was undertaken using a 25-part questionnaire. This paper addresses the method of interviewing, case material, and background concerning each couple and the summary of the results.     

A selectionist approach to reinforcement.

We describe a principle of reinforcement that draws upon experimental analyses of both behavior and the neurosciences. Some of the implications of this principle for the interpretation of behavior are explored using computer simulations of adaptive neural networks. The simulations indicate that a single reinforcement principle, implemented in a biologically plausible neural network, is competent to produce as its cumulative product networks that can mediate a substantial number of the phenomena generated by respondent and operant contingencies. These include acquisition, extinction, reacquisition, conditioned reinforcement, and stimulus-control phenomena such as blocking and stimulus discrimination. The characteristics of the environment-behavior relations selected by the action of reinforcement on the connectivity of the network are consistent with behavior-analytic formulations: Operants are not elicited but, instead, the network permits them to be guided by the environment. Moreover, the guidance of behavior is context dependent, with the pathways activated by a stimulus determined in part by what other stimuli are acting on the network at that moment. In keeping with a selectionist approach to complexity, the cumulative effects of relatively simple reinforcement processes give promise of simulating the complex behavior of living organisms when acting upon adaptive neural networks.     

Cancer and humiliation: The “catch 22” of disease

In the author's own words: I am a cancer patient involved in an agonizing struggle against disease. I decided to write about the humiliating aspects of cancer because I have experienced them firsthand. I know them all too well. I have incorporated my feelings about the humiliation of disease ... hoping they may help the reader better understand.Cynthia McGinnis Richards died of Hodgkin's Disease in February 1988.     

Sighting-eye dominance related to composite sidedness in classroom and clinic samples

Near-point and far-point binocular and monocular sighting tests given 20 high and 20 low achievers each from regular classrooms at Grades 4, 8, and 12 (N = 240) yielded significant chi 2 for differences of proportions of lateral agreement with sidedness in comparison to distributions unrelated to sidedness. Composite sighting congruent to sidedness yielded significant differences between classroom and reading clinic samples. The near-point binocular sighting test markedly influences distributions of combined scores in sighting.     

The Contribution of Attributional Style to Perceived Disability in Rheumatoid Arthritis: A Longitudinal Study

The current study investigated the influence of general causal attributions on self-reported physical disability over the course of 1 year in a sample of 42 patients with rheumatoid arthritis (RA). Participants completed measures of attributional style, pain, and disability; physician assistants completed objective measures of disability on two occasions, approximately 1 year apart. Results indicated that internal attributions for disease-unrelated negative events assessed at Time 1 were associated with lower perceived physical disability, whereas stable attributions for negative events were associated with greater perceived physical disability 1 year later. These findings are discussed in terms of behavioral and characterological self-blame models, respectively. Implications of our findings for clinical management of RA are also discussed.
