Good Memory or Delayed Response?
The action potential duration (APD) of ventricular myocytes depends on the length of the preceding diastolic interval (DI) in a relationship termed “electrical restitution.” The APD shortens with decreasing cycle length and thus with decreasing DI.1 The teleological advantage of this phenomenon is that it provides increased time for excitation-contraction coupling at long cycle lengths while pr...
متن کاملLocomotor delayed response in frontally ablated monkeys.
Monkeys which had been trained on a locomotor task, in which they were rewarded for (approaching a food cup located in a direction opposite to that of the stimulus, became severely impaired after bilateral 'ablations of dorsolateral prefrontal cortex, but not after damage t o other frontal lobe structures (Stepieli and Stamm 1969). The marked impairment, which was exhibited by responses indicat...
متن کاملNew Adaptive Designs for Delayed Response Models
Adaptive designs are effective mechanisms for flexibly allocating experimental resources. In clinical trials particularly, such designs allow researchers to balance short and long term goals. Unfortunately, fully sequential strategies require outcomes from all previous allocations prior to the next allocation. This can prolong an experiment unduly. As a result, we seek designs for models that s...
متن کاملAdaptive Designs for Delayed Response Models
Adaptive designs are effective mechanisms for flexibly allocating experimental resources. In clinical trials particularly, such designs allow researchers to balance short and long term goals of improving patient well being. This tradeoff often takes the form of trying to minimize patient losses during the experiment while simultaneously gathering sufficient information to support decisions abou...
متن کاملResponse acquisition by humans with delayed reinforcement.
The present experiment examined whether a response class was acquired by humans with delayed reinforcement. Eight white circles were presented on a computer touch screen. If the undergraduates touched two of the eight circles in a specified sequence (i.e., touching first the upper-left circle then the bottom-left circle), then the touches initiated an unsignaled resetting delay culminating in p...
