=== Early theorists ===
[[Wilhelm Wundt]] (1832–1920) emphasized the notion of what he called ''[[introspection]]'': examining the inner feelings of an individual. With introspection, the subject had to be careful with describing their feelings in the most objective manner possible in order for Wundt to find the information scientific.<ref name="Fuchs">{{cite journal| vauthors = Fuchs AH, Milar KJ |title=Psychology as a science|journal=Handbook of Psychology|year=2003|volume=1|issue=The history of psychology|pages=1–26|doi=10.1002/0471264385.wei0101|isbn=0471264385}}</ref><ref>{{cite book| vauthors = Zangwill OL |title=The Oxford companion to the mind|year=2004|publisher=Oxford University Press|location=New York|pages=951–952}}</ref> Though Wundt's contributions are by no means minimal, modern psychologists find his methods to be too subjective and choose to rely on more objective procedures of experimentation to make conclusions about the human cognitive process.{{citation needed|date=August 2024}}

[[Hermann Ebbinghaus]] (1850–1909) conducted cognitive studies that mainly examined the function and capacity of human memory. Ebbinghaus developed his own experiment in which he constructed over 2,000 syllables made out of nonexistent words (for instance, 'EAS'). He then examined his own personal ability to learn these non-words. He purposely chose non-words as opposed to real words to control for the influence of pre-existing experience on what the words might symbolize, thus enabling easier recollection of them.<ref name="Fuchs" /><ref name="Zangwill">{{cite book| vauthors = Zangwill OL |title=The Oxford companion to the mind|year=2004|publisher=Oxford University Press|location=New York|page=276}}</ref> Ebbinghaus observed and hypothesized a number of variables that may have affected his ability to learn and recall the non-words he created. One of the reasons, he concluded, was the amount of time between the presentation of the list of stimuli and the recitation or recall of the same. Ebbinghaus was the first to record and plot a "[[learning curve]]" and a "[[forgetting curve]]".<ref>{{cite book | vauthors = Brink TL | date = 2008 | chapter = "Memory."

[[Mary Whiton Calkins]] (1863–1930) was an influential American pioneer in the realm of psychology. Her work also focused on human memory capacity. A common theory, called the [[recency effect]], can be attributed to the studies that she conducted.<ref>{{cite journal| vauthors = Madigan S, O'Hara R |title=Short-term memory at the turn of the century: Mary Whiton Calkin's memory research|journal=American Psychologist|year=1992|volume=47|pages=170–174|doi=10.1037/0003-066X.47.2.170|issue=2}}</ref> The recency effect, also discussed in the subsequent experiment section, is the tendency for individuals to be able to accurately recollect the final items presented in a sequence of stimuli. Calkin's theory is closely related to the aforementioned study and conclusion of the memory experiments conducted by Hermann Ebbinghaus.<ref name="Matlin">{{cite book|last=Matlin|first=Margaret | name-list-style = vanc |title=Cognition|year=2009|publisher=John Wiley & Sons, Inc.|location=Hoboken, NJ|page=5}}</ref>

[[William James]] (1842–1910) is another pivotal figure in the history of cognitive science. James was quite discontent with Wundt's emphasis on introspection and Ebbinghaus' use of nonsense stimuli. He instead chose to focus on the human learning experience in everyday life and its importance to the study of cognition. James' most significant contribution to the study and theory of cognition was his textbook ''Principles of Psychology'' which preliminarily examines aspects of cognition such as perception, memory, reasoning, and attention.<ref name="Matlin" />

[[René Descartes]] (1596–1650) was a seventeenth-century philosopher who came up with the phrase "Cogito, ergo sum", which means "I think, therefore I am." He took a philosophical approach to the study of cognition and the mind, with his Meditations he wanted people to meditate along with him to come to the same conclusions as he did but in their own free cognition.<ref>{{cite web |title=René Descartes |url=https://www.iep.utm.edu/descarte/#H3 |website=Internet Encyclopedia of Philosophy |access-date=2 April 2020}}</ref>
