Unique Vocabulary:

Fistula: A surgical opening that is created to access a body cavity or an organ. In the context of the article, it refers to the opening that is made in the dog’s cheek to access the salivary duct.
Viscidity: A measure of the thickness or stickiness of a fluid. The authors use this term to describe the quality of the saliva secreted by the dogs.
Latent Period: The time delay between the application of a stimulus and the onset of a response. The authors measure the latent period of the salivary reflex in their experiments.
Unconditioned Reflex: A reflex that is naturally occurring and does not require prior learning. For example, the salivation response to food placed in the mouth is an unconditioned reflex.
Conditioned Reflex: A reflex that is learned through association with a previously neutral stimulus. For example, the salivation response to a specific sound that has been paired with food is a conditioned reflex.
Additional Reflex: A conditioned reflex that is evoked by a stimulus that is similar to the original conditioned stimulus.
Partial Reflex: A conditioned reflex that is evoked by a part of a complex stimulus.
Inhibition: A process that suppresses or reduces a response. The authors discuss how various stimuli can inhibit conditioned reflexes.

Anecdotes:

The Story of Nicolai’s Discovery: The article mentions that Nicolai discovered a dog that appeared to be able to distinguish between green and red but found that the dog was actually relying on a subtle difference in the keys used to present the stimuli, not on color perception.

Facts and Findings:

The dog’s sense of smell is highly developed and was not effectively studied in Pavlov’s lab: The researchers found it impossible to study smell in dogs effectively due to their highly acute sense.
Dogs can distinguish between different sounds and even perceive slight differences in pitch: The researchers found that dogs can distinguish between sounds that differ by only a quarter of a tone.
Dogs do not exhibit color vision: Researchers were unable to find evidence of color vision in dogs, suggesting that their visual perception is based on brightness and intensity rather than color.
The intensity of a photic stimulus depends on both its brightness and its size: Orbeli’s research suggested that the intensity of a visual stimulus depends on both the brightness of the light and the size of the illuminated or shaded area.
The nervous system responds more strongly to intermittent stimuli than to continuous stimuli: Orbeli’s research suggested that the nervous system is more likely to respond to an intermittent stimulus than to a continuous one.
