Schedule control of the vocal behavior of Cebus monkeys

The vocal behavior of three Cebus monkeys was maintained by fixed-ratio schedules of response dependent reinforcement at values between fixed-ratio 1 and fixed-ratio 15. In one monkey that was exposed to variable-interval, fixed-interval, and conjunctive fixed-ratio fixed-interval schedules of reinforcement, vocal responding occurred at a low rate, but schedule-appropriate patterns were maintained. The rates and patterns of responding engendered indicated that the vocal operant can be brought under schedule control in the monkey by the use of response-dependent reinforcement.     

Negation of Park's transformations

Zusammenfassung Parks Kritik beruht, meiner Ansicht nach, auf einem entscheidenden Mißverständnis meiner Intentionen: es geht mir überhaupt nicht um eine Argumentation gegen eine Transformationsgrammatik à la Chomsky, und nicht einmal in erster Linie gegen die Absicht mancher Psycholinguisten, eine derartige Theorie in ihren psychischen Funktionen aufzuzeigen. Ich möchte lediglich dafür plädieren, daß die Psycholinguistik in erster Linie psychologische (und nicht linguistische) Überlegungen und Modellvorstellungen als Leitlinien verwendet.     

Out of the frying pan into the goalbox

Using heat as a negative reinforcer was shown to be highly efficient in producing a discriminative response in Long-Evans rats. Heat failed to generate the emotional responses usually associated with shock as an aversive stimulus. In a separate study, using the heat-training procedure, age differences in the learning facility of Swiss/ICR (Ha) mice were detected.     

BASIC subroutines for on-line experiments using Hewlett-Packard computers

Modifications of the Hewlett-Packard version of the BASIC language to permit its use in data acquisition and control of on-line experiments are described. The resulting software system is an easy-to-use interpretative compiler.     

Sleep and overextinction of the GSR component of the orienting response

Overextinction of the GSR component of the orienting response was examined in a sample of 68 socially disturbed adolescents. Continued stimulus repetition beyond the point of habituation resulted in GSR return after 50–60 stimulus presentations. However, division of Ss into sleep and non-sleep groups using behavioral and self-report criteria, failed to support Sokolov’s (1963) notion that overextinction is accompanied by drowsiness. A possible explanation of these results is discussed.     

Lack of bilateral generalization of adaptation to auditory rearrangement

Intermanual transfer of adaptation to rearranged ear-hand coordination, generated by exposure to auditory rearrangement entailing 30 deg of functional rotation of the interaural axis by electronic pseudophones, was explored using 16 Ss. The results show that, except for one exposure condition, changes in ear-hand coordination that compensate the distortion induced by the pseudophones fail to transfer intermanually. These findings are similar to observations on visual adaptation.     

Fu tao: guidance in Taiwan seeks a value orientation

The guidance movement in Taiwan, only 20 years old, has paralleled ours in developing from vocational-educational advisement toward personal counseling. There is a basic conflict between traditional Chinese culture grounded in Confucian ideals and rules of behavior, and the highly individualized value orientation on which the counseling movement is predicated. This conflict leads Chinese guidance workers to search their tradition for a more appropriate balance between individual freedom and social responsibility. This article is a cross-cultural comparison exploring some critical implications for the value orientation of our Western democratic society and the counseling movement.
