A Definition of Psychological Thinking

Psychological thinking encompasses the examination and analysis of complex human emotions, motivations, and thoughts, with the aim of gaining a profound and nuanced understanding of human behavior. It explores a wide range of captivating topics, including cognitive science, neurology, social psychology, psychotherapy, and psychoanalysis. By delving into these domains, psychological thinking enables us to interpret behaviors with greater accuracy, while deepening our insight into the intricate workings of the human mind.

At its foundation, psychological research relies on the meticulous collection and analysis of data derived from carefully designed experiments and astute observations. This empirical approach allows researchers to generate robust hypotheses regarding the underlying reasons behind the multifaceted ways in which people think, feel, and act. Over the years, the field of psychological thinking has evolved and integrated numerous new concepts and methodologies, resulting in a more refined and comprehensive framework for comprehending the intricacies of human behavior.

The Origins of Psychological Thinking

Although it is challenging to pinpoint the origin of psychology, particularly considering the early theories about the mind in eastern practices like Buddhism, we can trace back the beginnings of psychology in western traditions to the early Greek philosophers. These philosophers, such as Socrates, Plato, and Aristotle, delved into the nature of the mind and explored concepts like perception, memory, and reasoning. Their inquiries laid the foundation for the development of psychology as a distinct field of study, shaping our understanding of human behavior and cognition.

Plato (428-348 BC), a renowned philosopher, embarked on the journey of unraveling the nature of the human mind. In his pursuit, he postulated that the human psyche, encompassing both mind and soul, served as the repository of knowledge, imprinted with all the wisdom it required. Hence, the process of learning was akin to unlocking this inherent knowledge, a concept he termed anamnesis.

Building upon Plato’s foundations, Aristotle delved deeper into the philosophical discourse surrounding the mind in his work ‘Para Psyche’ or ‘About the Mind’. Aristotle’s intellectual voyage led him to propose that the mind and soul possessed an independent existence, separate from the physical body. Moreover, he expounded upon the diverse manifestations of the soul, identifying three distinct souls: the plant soul, the animal soul, and the human soul.

A theory of impulses and urges

In his comprehensive exploration, Aristotle also formulated a theory of impulses and urges. For instance, he observed that the universal desire to reproduce stemmed from the influence of the plant soul. Additionally, Aristotle introduced the concepts of the ‘Id’ and ‘Ego,’ representing desire and reason, respectively. These two influential forces became significant determinants of human actions, a theme that would later be expanded upon by Freud, centuries later.

In the west, from the end of the classical period until the enlightenment, most discussions centred on christian and religious theology. It was not until the late 18th century that scientific thought re-emerged. Outmoded models of monarchy and religious interpretation of the natural world was challenged, and quickly disregarded. Although psychology was not to emerge as a study until the late 19th century, philosophical thinkers such as Descartes helped pave the way.

While visiting an awe-inspiring event in Paris displaying automatons, Descartes was deeply moved and began to reflect upon and examine the relationship between mind and body. His renowned phrase, “I think, therefore I am,” emerged as he formed his view of dualism, where mental and physical elements were two distinct aspects of our human experience.

During the nineteenth century, various biological scientists began to challenge the narrative inherited from biblical stories, culminating in Charles Darwin’s “Origin of Species.” This shift away from church orthodoxy paved the way for more freedom to investigate the nature of mind. German physiologist Wilhelm Wundt then opened the world’s first psychology lab in 1879, and this event can indeed be said to mark the beginning of the study of psychology.

The Modern Age of Psychological Thinking

Edward Titchener, a student of Wundt’s, formed the first prominent school in Psychology: the Structuralists. He postulated that consciousness could be studied scientifically through classifying and testing its components. This idea was logical based on the advancements made in biology and geology; however, he proposed to gain insight into human consciousness through ‘introspection,’ which does not follow scientific protocols like other disciplines do.

Meanwhile, in America, philosopher William James was to publish one of the first major works of psychology of its kind, “Principles of Psychology,” in 1890. James was one of the founders of the philosophical school known as Pragmatism. They held that the value of any concept depended upon its usefulness to the person who held it. Pragmatism emphasizes action over doctrine and experience over principles; it states that ideas take their meaning from their consequences. Therefore, ideas are methods and plans of action. When applied to psychological thinking, James believed that mental life and behavior reflect a person’s attempts to adapt to their environment. The functionalists were mostly concerned with the ability of the mind rather than the process of thought.

Drawing inspiration from Aristotle and the Greeks

Sigmund Freud, drawing inspiration from Aristotle and the Greeks, proposed that our minds or psyches can be divided into three distinct components: The id, the ego, and the super-ego. Our instinctive nature is inherited in its entirety within the id; it encompasses both sexual drive as well as a death wish. As we age and mature, so does our ego – functioning to create balance between what lies inside of us (the primitive impulses) versus external stimuli from society. Finally, values and morals are instilled through familial influence onto our super-ego.

Freud’s theories suggest that our minds are consistently in turmoil, and if this internal strife becomes too extreme it can cause psychological distress and general emotional imbalance. He argued that the events of our childhood profoundly shape us as adults, often shaping us on an unconscious level; revealed through dreams or seemingly random verbal slips referred to as ‘Freudian slips’. His research is the foundation for psychodynamic psychology – a style of therapy which allows individuals to explore these ideas further within psychoanalysis sessions.

The development of analytical Psychology

The most famous student of Freud, Carl Jung, went on to develop analytical Psychology with his take on psychodynamics, with a strong emphasis on dreams as an expression of the unconscious. Jung noted that the unconscious mind acted as a counter-measure to the conscious. Both are aspects of the human psyche that not only strives for balance but also for development through the process he called individuation. So that if we act in a way that is to our detriment, the unconscious will let us know if we can interpret its metaphorical language.

Furthermore, Jung believed that all people are connected by a collective unconscious, which contains archetypes – universal symbols with shared meaning across cultures. He argued that these archetypes were based on shared psychological experiences, and were expressed in ancient religious texts, myths and stories. Jung’s notion of the collective unconscious offers an explanation for why people around the world share similar beliefs and values.

With the invaluable contributions of William James, Sigmund Freud, and Carl Jung, the concept of humanistic psychology surfaced. It highlights each individual’s characteristic uniqueness to be embraced instead of shamed; it encourages self-reflection and growth to reach one’s fullest potential. At its core lies an empowering message that we should seek personal satisfaction from within ourselves rather than looking for validation externally or comparing ourselves with others. Humanistic Psychology propels us towards emphasising our unique value as humans.

In Reaction to the Psychodynamic Approach

In response to the psychodynamic school, behaviourists proposed a scientifically-tested approach for psychology. Led by John B. Watson’s methodological behaviourism, this method of understanding individuals was based on observing their observable behaviours and actions.

Watson proposed that psychology, when examined through a behaviourist lens, is an empirical discipline whose primary objective involves the prediction and control of behaviors. This idea reflects a scientific approach which can be demonstrated via experimentation. By studying observable behaviors, behaviourists aimed to uncover the underlying principles that govern human behavior and provide insights into the factors that shape our actions.

Behavior can be understood and modified

In the 1930s, psychologist B.F. Skinner took this concept to a new level and advanced the evolution of psychological thinking by proposing that internal experiences such as thoughts and feelings should be managed through the same controlling forces applied to visible behavior – this was coined ‘radical behaviourism.’ Skinner believed that behavior could be understood and modified by manipulating external stimuli and reinforcing desired responses. This perspective emphasized the importance of environmental factors in shaping behavior and challenged the traditional focus on internal mental processes in psychology.

By expanding on Watson’s ideas, Skinner advanced the field of behaviorism and provided a comprehensive framework for understanding human behavior. His work laid the foundation for the scientific study of behavior and influenced various areas within psychology, such as behavior modification and applied behavior analysis.

After WWII, The Humanist approach took off, with the work of Carl Rogers. In this approach, Rogers developed a client-centred method of psychology. In reaction to the behaviourists, he focussed on the subjective experience of the client rather than observable objective criteria. The humanist is driven by a desire to know what the client is like, and what the experience of being that client is. The empirical approach was eventually abandoned in favour of understanding the nature of each client. However there were certain assumptions, such as the inherent goodness of people, and that they will move toward growth if provided the right conditions. Also, humanism recognised the free will of the individual and the importance of their personal experience in explaining their mental states.

A respect for oneself and self-actualization

Abraham Maslow advanced the evolution of psychological thinking with his concept of humanism, illustrating a theory based on essential needs that can be arranged in a hierarchy. His model of needs begins with basic physiological requirement and progresses to safety, social connections, respect for oneself and ultimately self-actualization – all part of what has become known as “the third force” within psychology.

Maslow’s Hierarchy of Needs is a psychological theory that explains the different levels of human needs in order to achieve self-actualization. The pyramid-like model consists of five tiers, starting from basic physiological needs (air, food, water) at the bottom and working up to higher-level needs for self-fulfillment at the top. These five tiers include physiological needs, safety, love & belonging, esteem and self-actualization. Maslow argued that individuals must satisfy each level in order to reach the highest level of self-actualization.

Cognitive psychology is the branch of psychology that focuses on how people think, process information, and acquire knowledge. It assumes that behavior is the result of an individual’s cognitive processes such as perception, learning, memory and decision making. Additionally, it states that these processes can be studied scientifically through experiments and other forms of research. Cognitive psychology also suggests that individuals are active contributors to their own experience by constructing their own mental representations of the world around them.

A revolutionary form of Cognitive Behavioural Therapy

In 1955, Dr. Albert Ellis pioneered a revolutionary form of Cognitive Behavioural Therapy – Rational Emotive Behavior Therapy (REBT). REBT focuses on rectifying behavioural and emotional issues by replacing irrational beliefs with rational versions. The ultimate aim is to grant individuals the power to reclaim control over their lives through healthy thinking patterns.

If we want to alter our behavior and emotions, CBT and REBT suggest that it can be accomplished by changing the way we think. Rather than being only caused by an external event, these methods believe that feelings are largely determined by beliefs, attitudes and perspectives. Therefore if you change your thoughts, then you will likely experience a shift in how you feel emotionally as well as modify your actions accordingly.

Cognitive psychology is devoted to understanding the intricate link between stimuli and responses for a given individual. By analyzing how people process information, we can gain insight into what drives their reactions and subsequent behaviors. Therefore, cognitive approaches emphasise discovering these thought processes in order to understand why humans give specific answers even when faced with similar circumstances.

Today, humanistic psychology and the evolution of psychological thinking is still driven by personal values, yet has evolved to incorporate more than just cognitive or behavioural approaches. Nowadays, self-growth and exploration of the inner self are seen as essential parts of modern applied psychology – offering individuals valuable tools that help them shape a meaningful, goal orientated and purpose-driven life.

Evolution of Psychological Thinking: Conclusion

In conclusion, the evolution of psychological thinking from behaviorism to humanism to cognitive psychology has fundamentally shaped our understanding of the human mind and behavior. Each school of thought brought forward its unique perspectives, from the emphasis on observable behavior to the significance of personal experience and cognitive processes.

As we continue to integrate theories with practical wisdom, psychology remains a dynamic field. It continually adapts, drawing on the rich history of its theoretical foundations while embracing the individual’s journey towards growth and self-actualization. The convergence of these approaches in modern psychology provides a framework that equips individuals to navigate the complexities of the mind and lead more fulfilling lives. As the field moves forward, it will continue to be informed by its past achievements and the fresh insights that arise from living, evolving human experiences.
