Explanation:

According to the American Psychological Association(APA), an article is cited beginning with the author's last name immediately followed by the first name or initials. After the author's name, the year of publication is mentioned in parenthesis. The title of the article is mentioned after the year with only proper nouns capitalized. This information is succeeded by the name of the magazine in which it was published and the volume. The Issue number precedes the volume in parenthesis and lastly the page numbers. Thus, the final citation as per this format reads as:
