Radical Behaviorism,Stimulus Equivalence,and Human Cognition

The current paper represents an attempt to clarify the nature of the radical behaviorist’s perspective on human cognition. This attempt will involve an examination of recent behavioral research into the relationship between stimulus equivalence phenomena and symbolic behavior, and language more generally. This form of behavior analysis is offered as an alternative to, but not a replacement for, other methodological and conceptual approaches to psychology.

Measuring rationality independent of social desirability

The development of a test to measure Elli's concept of rationality is described. In the first study discussed, a 58-item test is developed to measure rationality, and the reliability and convergent validity of the test is described. In a second study, the discriminant validity of the test is examined. An attempt is also made to reduce social-desirability content in the test by eliminating items most highly correlated with a Social Desirability Scale. The final 44-item test is found to be high in both reliability and validity. The factor structure of the test is also examined.     

Prior context and the perception of lexically ambiguous sentences

The perceptual complexity of lexically ambiguous and unambiguous sentences was compared in three experiments. In Experiment 1, the report of ambiguous words from rapidly presented ambiguous sentences was worse than the report of corresponding unambiguous words from unambiguous sentences. Results of Experiment 2 showed that the effect was not reduced by the presence of prior biasing context within the sentence. Experiment 3 repeated the finding with a sentence meaning classification task. It was concluded that both meanings of a lexically ambiguous sentence must be computed, even when prior context makes one meaning more plausible than the other.     

The role of surface order and surface deletion in sentence perception

The perceptual complexity of intransitive adverbials, truncated passives and full passives was investigated in two experiments using rapid visual processing tasks. Both forms of passive were found to be more complex than the intransitive adverbials, presumably because of the lack of correspondence of surface and base orders. However, deletion of the logical subject in truncated passives did not increase their complexity relative to full passives.     

Patterns of self-disclosure in homosexual and heterosexual college students

Two hypotheses concerning self-disclosure were investigated and confirmed in the present study, comparing homosexual and heterosexual college students. The first hypothesis was that self-disclosure, as measured by the Jourard Self-Disclosure Questionnaire, would be positively correlated with psychological femininity. The second hypothesis was that homosexual males and heterosexual females would exhibit similar patterns of high disclosure and femininity. No significant differences were found in total disclosure between homosexuals and heterosexuals, although homosexuals disclosed less to father, and more to friends than to parents. The conclusion was that psychological femininity and masculinity are more important than biological sex in determining self-disclosure.     

Strategic Revenue Management under Uncertainty: A Case Study on Real Estate Projects in India

This paper proposes an approach for strategic revenue management under uncertainty for real estate projects. It integrates three modelling techniques: first, artificial neural network integrated support vector machines for forecasting the profit and loss‐making real estate residential projects; second, analytical network process approach using decision making trials and evaluation laboratory methodology for establishing interrelationships among factors; and third, multiobjective genetic algorithm approach for obtaining optimal numbers and types of apartments in a real estate project. We compare the respective revenues generated with the new number of apartments and price from the suggested revenue maximization model and that of the old practiced one through a case study of India.
