Conditioned Discrimination in the Planarian
Science, 1964To demonstrate classical conditioning in the planarian in a situation uncontaminated by the possible artifacts of pseudoconditioning or sensitization 30 Phagocata gracilis were successfully trained, by the use of directional shock as the unconditioned stimulus, to turn in one direction to a light, and in the ...

Forgetting of a drug-conditional discrimination
Physiology & Behavior, 1979Abstract Rats were trained on a drug-conditional discrimination to escape footshock in a T maze. Over a period of days rats learned to approach one goal box while under a pentobarbital drug state and another while under a saline drug state. Retention of this discrimination was then assessed with the rat under either a pentobarbital or saline state ...

Conditional Linear Discriminant Analysis
18th International Conference on Pattern Recognition (ICPR'06), 2006Dimensionality reduction by means of linear discriminant analysis (LDA) can generally lead to considerable improvements in classification accuracy and computation time. However, in supervised, pixel-based, image segmentation, the limiting factor of LDA that it cannot extract more than K - 1 features (K the number of classes) often prevents successfully

Drug discrimination using a Pavlovian conditional discrimination paradigm in pigeons
Pharmacology Biochemistry and Behavior, 1994Three pigeons were studied using a discriminated autoshaping procedure in which the presence or absence of methadone served as a conditional stimulus signalling which of two key light CSs would be followed by grain access. Drug sessions alternated randomly with no-drug sessions.

Benzodiazepine and anticholinergic drugs interfere with septo-hippocampal function in similar but not identical ways. They also share a number of common behavioural effects and, in particular, both classes of drug interfere with spatial memory in the Morris Water Maze--a test which is very sensitive to hippocampal dysfunction.

Successive and conditional discrimination learning in pigs
Animal Cognition, 2013We studied the ability of pigs to discriminate tone cues using successive and conditional discrimination tasks. Pigs (n = 8) were trained in a successive discrimination Go/No-Go task (Experiment 1) to associate a Go-cue with a reward at the end of a runway and a No-Go-cue with the absence of reward.

The present research investigated whether accuracy on one conditional discrimination could be increased by linking it to a second conditional discrimination. Three pigeons were trained in a discrete-trial procedure. In the first phase of training, a trial had one component, which was an identity delayed matching-to-sample (DMTS) task.

On the feasibility conditions of quantum state discrimination
2017 IEEE International Symposium on Information Theory (ISIT), 2017In this paper, we consider the quantum unambiguous discrimination problem of a set of linearly independent pure states. With a constructive procedure, we establish a necessary and sufficient condition for feasible POVM measurements for unambiguous quantum state discrimination.

Orienting response and discrimination conditioning
Physiology & Behavior, 1970Abstract The effects of habituation or no habituation trials, alternating and random pattern of CS+ and CS− presentations, and constant and variable intertrial intervals were observed on both rate and amount of discrimination conditioning of both first and second interval galvanic skin responses in 96 students.

Cue discriminability predicts instrumental conditioning
Consciousness and Cognition, 2018Charting mental acts that succeed or fail under unconscious instances of cognition informs debates on the nature and potential functions of consciousness. A prominent method to exclude conscious contributions to cognition is to render visual stimuli unconscious by short and pattern-masked presentations.
