<span>Elaborative rehearsal refers to the process of remembering
new information by linking it to previously learned information and making it meaningful in some way. </span>
<span>Using the mnemonic device “My Very Educated Mother Just Served Us Noodles” to recall the planets of the solar
system (Mars, Venus, Earth, Jupiter, Saturn, Uranus and Neptune) by taking the
first letter of each planet is an example of elaborative rehearsal. By linking the list of planets to other previously known
information, one is more likely to remember the list of planets.
Similarly, associating a newly met person's features with a previously known person's (your best friend's) features is an instance of elaborative rehearsal. </span>

Researchers often use computers in their experiments to keep from influencing the participants and to keep themselves <u>blind</u> regarding the conditions to which the participants have been assigned.
<h3><u>Why is research blinding crucial?</u></h3>
Blinding is crucial to prevent bias (such as observer bias and demand characteristics) and guarantee the internal validity of a study.
Participants may alter their behavior in ways that affect the outcome that researchers are aiming to measure if they are aware of whether they are in a control or treatment group. If those providing the treatment are aware of the participants' assigned groups, they may treat them differently, which could either directly or indirectly affect the outcome.

Answer:involuntary; voluntary
Explanation:In classical conditioning, learning occurs involuntary because we respond to stimuli automatically and naturally. We start to associate certain stimuli with each other and the first encountered stimulus is the one that triggers natural and automatic response from us, and this stimuli is referred to as unconditioned stimulus and it will yield an automatic response that we have not learned before. Like when someone soothes you with a hug after a stressful day , you feel that arousal which occurs automatic and it is an involuntary response.
In operant conditioning we actual embark on a journey to learn such as observational learning in which we study others behavior so that we can imitate it.
