Vasomotor response in human subjects: Conditioning and pseudo-conditioning

Escape and avoidance conditioning in human subjects without their observation of the response.

An invisibly small thumb-twitch increased in rate of occurrence when it served, via electromyographic amplification, to terminate or postpone aversive noise stimulation. Subjects remained ignorant of their behavior and its effect. Their cumulative response curves resembled those obtained in similar work with animals. Other subjects, informed of the effective response, could not produce it delib...

Eyelid conditioning and arousal in schizophrenic and normal subjects.

A group of schizophrenic patients were compared with normal Ss on an eyelid-conditioning task. All Ss received SO trials to either a light or a tone CS and the UCS was an air puff to the eye. The principal findings were as follows: (a) the number of conditioned responses was shown to be related to level of skin potential in both normal and schizophrenic Ss, (b) the schizophrenic group gave more...

Conditioning of an autonomic response in Crustacea.

Reports on experience-dependent changes in invertebrate autonomic function are few. In the crab Chasmagnathus, repeated presentations of a visual danger stimulus (VDS) elicit long-term cardiac adjustments. Although these changes can be explained in terms of an associative process, they do not necessarily indicate an anticipatory conditioned response. In the present work, we investigated anticip...

Physiological Responses to Two Hypoxic Conditioning Strategies in Healthy Subjects

Objective: Hypoxic exposure can be used as a therapeutic tool by inducing various cardiovascular, neuromuscular, and metabolic adaptations. Hypoxic conditioning strategies have been evaluated in patients with chronic diseases using either sustained (SH) or intermittent (IH) hypoxic sessions. Whether hypoxic conditioning via SH or IH may induce different physiological responses remains to be elu...
