Various psychologists from history have significantly influenced our current understanding of psychology. This article will explore three of the most impactful psychologists: Carl Jung, Sigmund Freud, and Abraham Maslow. Sigmund Freud was born in May 1856 in Austria to Galician Jewish parents. He was a neurologist who made numerous significant observations, but this article will focus on his theories concerning the conscious and unconscious mind, psychosexual development, dream analysis, and psychoanalytic theory. Freud’s concept of the mind suggested that it comprises three distinct personalities: the id, ego, and superego. The id represented repressed desires, driven by human instinct, while the superego encompassed the adherence to societal rules and morals. The ego served as the intermediary between the two, striving to satisfy both realistically. Furthermore, Freud indicated that the ego formed during childhood by the age of three, and the superego emerged by the age of five as the ultimate personality. He believed that anxiety, neurosis, and maladaptive behavior stemmed from an imbalance among these personalities. Freud’s subsequent theory on psychosexual development was regarded as unsettling and contentious, positing that an adult’s behavior and personality emerged from psychosexual stages experienced during childhood. This indicated that children derived pleasurable urges from the id at specific body areas known as erogenous zones. These stages included oral, anal, phallic, latency, and genital. Freud suggested that difficulties faced during childhood could resurface and distress the individual later with mental health issues. In his book: *The Interpretation of Dreams*, he asserted that dreams originated from the unconscious mind, reflecting the id’s unmet desires attempting to infiltrate the conscious. The intent behind an unrealistic dream was purportedly to fulfill inappropriate wishes, employing symbolism to obscure and disguise what is considered unsuitable. Consequently, Freud devised various techniques to interpret and comprehend dreams. These strategies included condensation, displacement, representation, and secondary revision. Lastly, the psychoanalytic theory elaborated on human behavior. Similar to psychosexual development, Freud acknowledged that early childhood experiences play a crucial role in shaping adult personality, particularly regarding trauma. He theorized that these experiences might be hidden in our consciousness, potentially causing future issues. Thus, he established psychoanalysis, represented by the psychoanalytic theory, as a form of talk therapy intended to aid patients with mental health conditions by delving into these unexpressed emotions. Due to his contributions, he is regarded as the ‘father of psychoanalysis.’
One concept within psychoanalysis is defense mechanisms, which are unconscious tactics that support an individual’s ego—the rational aspect of the mind—in alleviating anxiety stemming from internal conflicts. These internal conflicts arise between the impulses conveyed by the id and the ethical expectations of the superego, which serves as a self-critical conscience. The internal conflicts and the strategies employed by the ego are believed to drive an individual’s actions as they illustrate how a person unconsciously shields themselves from emotional distress and turmoil. Generally, the ego distorts or redirects the thoughts and feelings produced by the id to conform with the superego. Common examples include projecting the id’s impulses onto others, allowing the mind to persuade the superego that they are superior to such primal urges. Displacement is another defense mechanism where a person shifts unacceptable thoughts and feelings—often anger or jealousy—onto a target deemed acceptable by the ego/superego. Sublimation, an alternate form of projection, occurs when an individual channels their unconscious desires into constructive and more socially acceptable activities. For instance, a surgeon might be sublimating underlying aggression into performing operations intended to heal individuals.
Freud proposed the notion of an unconscious life “drive” or instinct known as libido, thought to energize or sustain the id’s mental processes. This instinct aims to evade emotional or physical suffering, fulfill basic bodily needs, and satisfy other primal urges. This instinct forms the second primary component of Freudian psychoanalytic theory, postulating that all human behavior is motivated by sexuality; in this framework, sexuality encompasses any aspect that can yield pleasure. Reflective of many psychoanalytic elements concerning the unconscious, this instinct encounters opposition from the ego or superego, with this inner conflict governing aspects such as impulse control. For example, a person with an excessively active libido and a weak superego may struggle with feelings of remorse or critical assessment regarding the consequences of their actions driven by unconscious desires.
*Maslow’s Hierarchy of Needs* represents a prominent theory articulating human motivations, beginning with fundamental needs and progressing to more intricate concepts. This theory was formulated and introduced by American psychologist Abraham Maslow in
