PSYCH: You want to classically condition your pet. What is the correct order you should present the stimuli to your pet?
jenyasd209 [6]

Answer:

unconditioned stimulus

neutral stimulus, unconditioned stimulus

Explanation:

Classical conditioning is the process of linking two stimuli to produce a response. There are 3 phases for classical conditioning:

  1. Phase 1 (before conditioning): During this phase an unconditioned stimulus is paired to produce an unconditioned response. An unconditioned response naturally triggers a response.
  2. Phase 2 (During conditioning): This phase involves pairing a neutral stimulus with an unconditioned stimulus so that the neutral stimulus becomes the conditioned stimulus. The neutral stimulus does not naturally trigger a response.
  3. Phase 3 (after condition): In this phase only the conditioned stimulus is presented to produce a conditioned response. The conditioned response triggers a response after pairing with an unconditioned stimulus

Serga [27]

Answer:

The correct answer is A. organizing.

Explanation:

Organizing is the quality of being able to put your work as to be as efficient as possible. As the definition above says, <em>organizing includes finishing or getting rid of the no important stuff and, as a consequence, directing our attention to the priority tasks. </em>

The response C. is very similar to organizing, but it is a part of it. We can say that organizing includes prioritizing (which is the act of deciding what thing has greatest level of importance and needs to be done first.

Consequences mean the relationship between the reason and the result. In this example, we lack the outcome that would make us focus on important tasks.
