Most lab-control programs for small (4K) computers must be written in assembly or machine language, making it necessary for the user to expend considerable time and effort both in learning assembly-programming skills and in writing programs. One of the most frequently used small laboratory computers (the PDP-8 series) can, however, be programmed to provide sophisticated control using an algebraic language (FOCAL) in as little as 4K memory locations. The FOCAL language includes a special program sequence, FNEW, which provides capacity for a single user-defined function written in machine language. This paper describes an implementation of the FNEW sequence that permits execution of multiple user-written machine language subprograms within a FOCAL program. Use of this capability in the context of process-control problems in the behavioral laboratory is discussed and illustrated. 相似文献

Two monkeys were trained to press and hold down a telegraph key in the presence of a red light. Subsequent release of the key in response to a white cross superimposed on the red background was followed by reinforcement. Key release in response to a white circle on the red background was never reinforced. Latencies for the key release response to the reinforced stimulus (cross) were considerably shorter and less variable than those to the unreinforced stimulus (circle). 相似文献

A rat was trained on a schedule that programmed reinforcements only when a minimum waiting time between successive responses was exceeded (DRL schedule). It was observed to fill much of the pause between lever presses with a stereotyped behavioral chain: it would take its tail in its mouth and nibble it. This behavior was shown to be functionally related to the efficiency with which the subject spaced its responses. It is thought to have served as mediating behavior, providing discriminating stimuli for appropriate lever presses. 相似文献

Male-female differences on the Wechsler Preschool and Primary Scale of Intelligence were examined for 1200 children aged 4–6.5 yr. Results provided fundamental support for previous work with older children showing better female performance on memory and psychomotor tasks and better male performance on spatial tasks, although the distinctions in performance were not as clear as with older children. 相似文献

Emotional support is known to provide psychosocial benefits for women with breast cancer, but women can experience a mismatch between support that is wanted and support that is received from their personal supporter. The role of wanted and unwanted support in psychosocial adjustment was examined in 79 women recovering from breast cancer. Four distinct patterns of desired support actions were found using cluster analysis. Patterns of wanted support were not related to better or worse psychosocial adjustment. However, a misalignment of support between the provider and the receiver significantly influenced psychosocial adjustment, and unwanted but received support (support commission) was uniquely associated with poor psychosocial adjustment. Clinical interventions using the support instrument could help match support providers' actions to receivers' preferences. 相似文献
