The thought translation device trains locked-in patients to self regulate slow cortical potentials (SCP's) of their electroencephalogram (EEG). After operant learning SCP control, select letters, words or pictograms in a computerized language support program. Results five respirated, locked-in-patients are described, demonstrating the usefulness as an alternative communication channel motivated totally paralyzed with amyotrophic lateral sclerosis.
In three experiments, access to wheel running was contingent on lever pressing. each experiment, the duration of reduced gradually 4, 5, or 6 s, and schedule parameters were expanded gradually. The sessions lasted 2 hr. Experiment 1, a fixed-ratio 20 controlled typical break-and-run pattern pressing that maintained throughout session for 3 rats. 2, fixed-interval min rats, 1 rat, rate positively accelerated between reinforcements. 3, variable-ratio 35 in effect at very stable pace rats; an...
With a customary arrangement of three horizontally aligned stimulus/response keys, two rhesus monkeys learned conditional hue and line discriminations—an “identity‐matching” procedure. First, sample stimuli were always presented on the center key, comparison side keys. Next, was allowed to appear any one with comparisons remaining two. The change from fixed variable locations caused horizontal vertical lines lose control over animals' responses; discrimination deteriorated. This not true for...
Three rats had previously acquired a simultaneous matching‐to‐sample performance with steady and blinking lights. In training, the sample stimulus always appeared on middle of three horizontally arranged keys comparison stimuli side keys. Experiment 1, any remaining two. The broke down variable locations; did not control responding to when it key, but retained key (as in training). 2, were trained left key. When either locations (left or key), for both locations. then keys, as transfer...
Vervet monkeys received food reinforcement contingent on autogrooming. Experiment 1 reinforced grooming a schedule of increasing intermittency and increased in frequency duration; with only pauses reinforced, decreased duration. 2 demonstrated differentiation operant autogrooming; each session different single form was (for example, the tail only), that while other forms became less frequent. In 3 scratching succesfully conditioned method selectively variety behavior; shift form. 4, no...
Steady and blinking white lights were projected on three nose keys arranged horizontally one wall. The procedure was a conditional discrimination with sample stimulus presented the middle key comparison stimuli side keys. Three rats acquired simultaneous “identity matching.” Accuracy reached 80% in about 25 sessions 90% or higher after 50 sessions. Acquisition progressed through several stages of repeated errors, alternation between from trial to trial, preference specific stimuli, gradual...
Three experiments explored whether access to wheel running is sufficient as reinforcement establish and maintain simple conditional visual discriminations in nondeprived rats. In Experiment 1, 2 rats learned press a lit key produce running; responding was virtually absent when the dark, but latencies respond were longer than for customary food water reinforcers. Increases intertrial interval did not improve discrimination performance. 2, 3 acquired go‐left/go‐right with trial‐initiating...
A miniature digital camera, QuickCam® Pro 3000, intended for use with video e‐mail, was modified so that snapshots were triggered by operant behavior emitted in a standard experimental chamber. With only minor modification, the manual shutter button on camera replaced simple switch closure via an I/O interface controlled PC computer. When activated switch, took snapshot of subject's at moment. To illustrate experiment designed to examine stereotypy and variability topography under continuous...
