Historical Development of Experimental Psychology: From Philosophy to a Distinct Scientific Field

First, the historical development of experimental psychology should be explored. As stated by Lawson et al. (2015), authors of the book A History of Psychology, the historical development of experimental psychology traces its roots to the 19th century, marking a significant shift in the study of the human mind and behavior. Lawson et al. (2015), add that before this period, psychology was predominantly a philosophical discipline, exploring questions about the nature of the mind and its connection to the physical world. However, it was during this era that experimental psychology emerged as a distinct scientific field, employing empirical methods to study the complexities of human cognition and behavior (Lawson et al., 2015). The question to be asked here is how experimental psychology is separated from philosophy as a scientific field. How exactly did this happen, and mainly thanks to whom? According to the famous psychologist Titchener (1921), who made many contributions to psychology, the field of psychology today owes this to Wilhelm Wundt, one of the founders of modern psychology who founded the first psychology lab in 1879 in Leipzig, Germany (Figure 2). Titchener (1921), who worked for years under Wundt's supervision, also states that Wundt's contributions were instrumental in shaping the field of experimental psychology and inspiring future generations of researchers. Titchener's (1921) work, emphasized the importance of objective observation and measurement, setting the stage for the development of experimental methods and apparatus. Psychological historians Blumental and Danziger (2001) support this notion; according to them, Wundt's approach to psychology aroused interest and curiosity all over the world and led to the establishment of similar experimental psychology laboratories in various countries. So, what important developments took place after Wilhelm Wundt? Professor Mandler (2011) from the University of California stated that numerous milestones and influential figures have further advanced the field's progress. For example, the advent of behaviorism, led by psychologists such as John B. Watson and B.F. Skinner brought attention to observable behavior and learning processes, and Sigmund Freud's psychoanalytic theories introduced the exploration of the unconscious mind and the significance of early childhood experiences (Mandler, 2011). Besides, the historical development of experimental psychology consists of different perspectives and contributions; Famous psychologists such as Ivan Pavlov, Jean Piaget, Carl Rogers, and others each cover their work that has left an indelible mark on the field (Mandler, 2011). Through their joint efforts, experimental psychology has grown into a multidisciplinary science that combines insights from biology, neuroscience, computer science, and other related fields (Mandler, 2011). Finally, Kantowitz et al. (2014) stated that experimental psychology today is an evolving discipline that constantly develops and expands the understanding of the human mind and behavior. In addition, the rich historical fabric of milestones, influential figures, and paradigm shifts reached today's understanding and paved the way for future advances in the fascinating field of experimental psychology (Kantowitz et al., 2014).

Exploring Research Methods in Experimental Psychology

Now that the outlines of experimental psychology are understood, it's time for research methods. How is research done in the field of experimental psychology? What are the research methods? According to McGuigan (1993), a psychologist, and author who has written several psychology books, empirical research plays a crucial role in advancing our understanding of the human mind and behavior within the field of experimental psychology; by employing rigorous and systematic methods, empirical research allows psychologists to investigate hypotheses, test theories, and draw reliable conclusions based on evidence. Additionally, the importance of empirical research lies in its objective and data-driven approach, which helps to establish the validity and generalizability of findings (McGuigan, 1993). Psychology professor Davis (2008), explained the data collection methods: experimental psychology employs various research methods, including experiments, surveys, and observations. Davis (2008), explained that while experiments involve manipulating variables to study cause-and-effect relationships and underlying mechanisms, surveys collect data from a large number of individuals to explore correlations and gain insights into thoughts, attitudes, and behaviors, and observations allow researchers to study behavior in natural settings, uncovering patterns, dynamics, and contextual influences. Each research method in experimental psychology offers unique advantages and limitations. By utilizing empirical research methods, experimental psychologists can gather robust evidence, contribute to theoretical frameworks, and make meaningful contributions to our understanding of the human mind and behavior.

Understanding the Human Mind

What can be learned about the human mind and the research area of experimental psychology? Psychologist Hebb (2014), who was influential in the field of neuropsychology, deals with the human mind in his book Essay on Mind. Hebb (2014), stated that the human mind is a remarkable entity that encompasses our thoughts, emotions, perceptions, memories, and more, and it serves as the epicenter of our behavior and cognition, influencing how we perceive, interpret, and respond to the world around us. perspective highlights the significance of the human mind in our daily experiences and interactions with the world. Besides, Hebb (2014) suggests that our mind not only receives sensory information but also actively interprets and processes it, influencing how we perceive and make sense of our surroundings, the mind's functions extend beyond basic perception, as it also incorporates our emotions, memories, and higher cognitive processes. By recognizing the essential role of the mind, Hebb (2014) emphasizes the intricate connection between our mental processes and our behavior, our thoughts, emotions, and memories influence our actions, decisions, and interactions with others. Therefore, understanding the workings of the human mind becomes crucial for comprehending the complexities of human behavior and cognition.

Furthermore, experimental psychologist Dember (1960) addresses perception in his book The Psychology of Perception. Dember (1960) discusses how perception is a fundamental cognitive process that allows us to make sense of the sensory information we receive from our environment and involves the brain's interpretation and organization of sensory stimuli, shaping our understanding of the world. In more detail, the process of perception encompasses various stages, including sensation, selection, interpretation, and integration (Dember, 1960). Although not included in Dember's (1960) discussion, Styles (2006), author of the book The Psychology of Attention, deduced that attention plays a crucial role in perception by selectively focusing our awareness on specific stimuli or aspects of our environment. She added that attention acts as a filter, determining which information receives priority for further processing and it influences our ability to concentrate, perceive details, and allocate cognitive resources (Styles, 2006). The study of perception and attention in experimental psychology sheds light on the mechanisms underlying these processes, revealing how they shape our perception of reality and influence our cognitive experiences.

Additionally, another element known as memory should be mentioned. Acknowledged for his work in cognitive psychology, Klein (2015) defined memory as one of the basic cognitive functions that enable us to encode, store, and retrieve information. Memory is the mechanism through which we retain knowledge and experiences over time (Klein, 2015). Experimental psychology recognizes different types of memory, including sensory memory, which holds sensory impressions for a brief period; short-term memory, responsible for temporarily holding information in conscious awareness; and long-term memory, where information is stored for extended periods, potentially indefinitely (Klein, 2015). By exploring the complexities of memory in experimental psychology, Klein (2015) emphasized that researchers gain insights into how information is processed, stored, and retrieved, illuminating the intricate interplay between perception, attention, and memory in shaping cognitive abilities.

Finally, the process of thinking and decision-making, as highlighted by Minda (2020), Professor of Psychology at the University of Western Ontario, plays a pivotal role in shaping our everyday lives; these cognitive processes encompass a range of mental activities, including reasoning, problem-solving, and judgment formation. According to Minda (2020), problem-solving involves identifying challenges, generating potential solutions, and selecting the most effective course of action. Similarly, decision-making entails making choices among alternative options based on available information and personal preferences (Minda, 2020). Insights into the intricacies of thinking and decision-making processes, as emphasized by Minda (2020), allow for the understanding of how the complexities of daily life are navigated, offering valuable knowledge for the improvement of problem-solving abilities and the enhancement of the quality of decision-making.


In conclusion, experimental psychology serves as a gateway to understanding the complexities of the human mind, offering valuable insights into perception, attention, memory, and thinking processes. Through meticulous empirical research, experimental psychologists have unraveled the mysteries of these cognitive functions, shedding light on their mechanisms and implications (Blumental and Danziger, 2001; Davis, 2008; Dember, 1960; Hebb, 2014; Kantowitz et al., 2014; Klein, 2015; Lawson et al., 2015; Mandler, 2011; McGuigan, 1993; Minda, 2020; Styles, 2006; Titchener, 1921). The historical development of experimental psychology marks a significant shift from philosophy to a distinct scientific field. Visionaries like Wilhelm Wundt paved the way for empirical methods and objective observation, inspiring future generations of researchers to explore the depths of human cognition and behavior. Research methods in experimental psychology, including experiments, surveys, and observations, provide rigorous and systematic approaches to investigating hypotheses and drawing reliable conclusions. By employing a combination of methods, researchers gain a comprehensive understanding of complex phenomena and contribute to the advancement of knowledge. The human mind, as described by Hebb (2014), encompasses our thoughts, emotions, perceptions, memories, and more, shaping our behavior and cognition. Understanding the intricacies of perception, attention, memory, and thinking processes illuminates how humans interpret sensory information, allocate cognitive resources, retain knowledge, and make decisions. Overall, the expedition into the realms of experimental psychology deepens our appreciation for the power and intricacies of the human mind. A pathway to personal growth, an improved understanding of oneself and others, and the potential for creating positive change in lives and society are offered by experimental psychology. As the field continues to evolve, further insights into the mysteries of the mind will undoubtedly be uncovered by experimental psychology, fueling the continuous exploration of human cognition and behavior.
