Answer:
The answer to the question: What type of design was used by Watson and Rayner (1920), would be: Controlled experiment on one individual with no control subjects.
Explanation:
The "Little Albert" experiment, which was conducted by John B. Watson and Rosalie Rayner, and which was published in 1920 in the <em>Journal of Experimental Psychology </em>became famous because of its use of the Pavlovian theory of classical conditioning, to show how phobias could develop in humans, given the correct stimulation, and in direct response, without intervention from any abilities, or extras. There was just stimulus, and learned response. In Little Albert, an infant, and the only subject of the Controlled Study, was exposed first to some animals and objects with certain characteristics, and later exposed to a sound that scared him. In time, he learned to associate the stimuli (animals with the sound that scared him) and his response was to cry when the animals, or objects with similarities, appeared before him. Thus, a phobia was developed. It was a controlled experiment because all variables were under the control of the researchers, including the number of subjects, the type of stimulus that would be used. Nothing was random, all was selected by the researchers, with the only intention of seeing how the fear towards something developed in direct line with a harmful stimulus and a neutral stimulus.
Answer: D. glutamate
Explanation:
The GLUTAMATE HYPOTHESIS OF SCHIZOPHRENIA is based around the belief that schizophrenia may be due to a low level of activity of glutamate in the glutamate synapse, especially in the prefrontal cortex.
This is because, increased levels of dopamine have been known to lead to schizophrenia according to the DOPAMINE THEORY of schizophrenia and dopamine inhibits the release of glutamate as well as inhibiting neurons that glutamate excites.
In short, INCREASED levels of dopamine show symptoms similar to DECREASED levels of glutamate meaning that schizophrenia may be due to a deficiency of activity of the glutamate synapse .
The cause of foodborne illness that occur afterward is
classified as a physical hazard. A physical hazard takes place when it is
either in contact or having no contact but involves the environmental hazards
such as having a silver mental from a faulty can opener can lead the food
contaminated because it is considered to be a physical hazard.
