Enzyme Induction as an All-or-none Phenomenon.
The phenomenon of enzyme induction (enzymatic adaptation) has been observed in a variety of micro-organisms. One of the most carefully studied examples, largely the work of Jacques Monod and his colleagues at the Institut Pasteur, is the induction of the synthesis of the enzyme j3-galactosidase in the bacterium Escherichia coli.", 2 This enzyme, not otherwise present in appreciable amounts, is ...
متن کاملAll-or-None Subprocesses in the Learning of Complex Sequence+
This paper reports a study designed to investigate whether the all-or-none conception of the learning process can be extended to a learning task more complex than conditioning or simple verbal association. The experimental task is to learn numerical sequences by anticipating each new member of the sequences. Although the obtained sequence learning appears very complex, it proves to be analyzabl...
متن کاملIs consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink.
Several theories of the neural correlates of consciousness assume that there is a continuum of perception, associated with a gradual change in the intensity of brain activation. But some models, considering reverberation of neural activity as necessary for conscious perception, predict a sharp nonlinear transition between unconscious and conscious processing. We asked participants to evaluate t...
متن کاملThe gastric secretory response to insulin: an 'all-or-none' phenomenon?
Dogs were prepared with Pavlov pouches which could be perfused with saline so as to detect rapidly changes occurring in acid secretion.Dose-response studies were performed by the intravenous injection of insulin (0.06, 0.12, 0.25, 0.5, or 1.0 unit/kg). Both the magnitude of peak response and the duration of response were dose-related and both were related to the magnitude of fall in plasma gluc...
متن کاملAll-or-none bottleneck versus capacity sharing accounts of the psychological refractory period phenomenon.
The goal of the present experiment was to test the predictions of Central Bottleneck and Central Capacity Sharing models. According to the Central Bottleneck model, dual task interference, as observed in the PRP paradigm, is caused by an all-or-none bottleneck in information processing. The Central Capacity Sharing model postulates that dual task interference is caused by a capacity limited pro...
