Freud's model of the mind

Freud developed a theory to explain how the human mind functions, comparing it to an iceberg to illustrate its different levels. In this analogy, only a small part of the mind is visible and accessible, while a much larger portion remains hidden and influences us without our conscious knowledge.

Levels of the mind

• Conscious - This is the part of the mind that holds thoughts, feelings, and perceptions we are currently aware of, like the tip of the iceberg visible above the water.
• Preconscious - This acts as a bridge between the conscious and unconscious, containing memories and information that are not in immediate awareness but can be easily recalled.
• Unconscious - The largest part, hidden below the surface, which stores repressed thoughts, desires, and memories that are not accessible to conscious awareness but still drive behaviour.

Freud believed that all thoughts originate in the unconscious. Some make it through to the preconscious and then to conscious awareness. However, others are actively pushed back or repressed into the unconscious. This repression is dynamic and ongoing, as these hidden thoughts continually try to surface. Even though we are unaware of them, unconscious elements motivate much of our behaviour.

Structure of personality

Freud proposed that personality consists of three related elements. These parts interact to shape how we think, feel, and behave, often creating internal conflicts that the mind must resolve.

The id and the pleasure principle

The id is the first part of personality to develop, present from birth. It represents our basic biological drives and instincts, focusing on survival needs and immediate pleasure.

Key features and operating principle:

• The id is mainly concerned with things which ensure that the person survives and with those things which give it pleasure, such as food, comfort and avoiding pain.
• It follows the pleasure principle, which means it seeks to maximise pleasure and minimise discomfort without considering consequences or reality.
• The id demands that its needs be satisfied immediately and at all costs.

The ego and the reality principle

As the child grows and interacts with the world, the ego emerges to balance the id's demands with real-world constraints. This part is the second part of personality to appear.

Key features and operating principle:

• The ego allows the child to realise that talking, explaining, planning, negotiating, asking, etc., will be more effective in satisfying id's demands.
• It follows the reality principle, which involves delaying gratification and using strategies like negotiation or compromise to meet needs effectively.
• The child has to become more realistic and realise that making demands which are not met is a waste of energy.

The superego and the morality principle

By around age three to five, the superego forms as the child internalises societal rules and moral standards from parents and culture. This part is the third part of personality.

Key features and operating principle:

• The superego makes sure the ego does not use unacceptable means to satisfy id's demands.
• It follows the morality principle, which prioritises ethical conduct over pleasure or reality.

Interactions between personality parts

The three elements of personality do not function in isolation; they constantly interact, often leading to internal struggles. These interactions explain why people experience inner conflicts.

Defence mechanisms

Freud described defence mechanisms as unconscious strategies the ego uses to protect itself from anxiety caused by conflicts between the id, superego, and reality. These mechanisms distort or deny reality to reduce stress, but they can influence behaviour without the person's awareness.

Purpose and function of defence mechanisms

Defence mechanisms help the ego manage overwhelming emotions or unacceptable impulses by keeping them out of conscious awareness. This process is automatic and unconscious, allowing the person to function without facing painful truths directly. The ego uses these defences to deal with the stress caused by the conflicting demands of id and superego.

Examples of defence mechanisms

Freud identified several defence mechanisms, with some particularly relevant to explaining behaviours like aggression.

A key example:

• Displacement - This occurs when unacceptable impulses are redirected from their original target to a safer substitute. The target can be a person or an object that can serve as a symbolic substitute. For instance, someone who is frustrated by his or her superiors may go home and kick the dog or hurl verbal abuse at a family member. It has also been offered by some psychologists as a factor in domestic violence and road rage.

Role in behaviour and aggression

Defence mechanisms like displacement can account for aggressive behaviour by providing outlets for internal conflicts. Displacement is an example of a defence mechanism that can explain aggressive behaviour.
