Question

Transcribed Image Text:Researchers investigating the effect of exercise on cognitive functions conducted a con-
trolled experiment in which rats were randomly assigned to sedentary (Sed), low-intensity
exercise (Low-Ex), or high-intensity exercise (High-Ex) groups. During this exercise regi-
ment, rats were also trained to navigate a specialized water maze, and their escape la
tency, the time it took them to escape the maze, was recorded. The results of this experi-
ment are depicted in the figure below.

- In the example below, the author uses both ideas and a quotation from a published work. Review the sample to determine if the author correctly cited their source and select the answer that best represents your choice. According to one author, “Adult learners have different learning styles that must be assessed prior to initiating any educational session” (Russel, 2006, p.349). One theory of learning styles proposed by Russell is that they relate to using senses in learning and are developed during one’s childhood. The most commonly employed learning styles is visual, followed by auditory, and kinesthetic. Visual learners are those who interpret information through graphic or pictorial representation. Auditory learners are those who have a preference for hearing versus reading instructions. Kinesthetic learners are those who want to interact or make something happen in order to learn. a.
