Theories of Stress

Stress is a physical response to demanding situations, which triggers a fight or flight response.
The Biological Theory of Stress, proposed by Selye, states that the body responds to all types of physiological stress in the same way, known as the General Adaptation Syndrome.
The Transactional Model of Stress and Coping, by Lazarus and Folkman, implies that individuals assess stressful situations and respond according to the resources available to them.
Transactional Theory views stress as a result of an imbalance between perceived demands and perceived resources.

Theories of Behavioural Addiction

Behavioural addiction, also known as a process addiction, involves compulsive engagement in a behaviour despite negative consequences.
The Disease Model proposes that addictions are similar to physical illnesses and are likely due to genetic factors.
The Learning Theory suggests that addictive behaviours are learned through observed consequences and rewards.
The Cognitive Theory views addictions as a result of irrational thought patterns or distorted thinking.

Theories of Physiological Addiction

Physiological addiction refers to a state where the body relies on a substance to avoid withdrawal symptoms.
The Physical Dependence Model emphasises biological changes in the brain due to repeated exposure to a substance causing dependence.
The Addiction Cycle Model outlines the continuous cycle of euphoria, crash, and craving leading to addiction.
The Dual Diagnosis Model accounts for the instances where addiction and mental health disorders co-occur.

Remember to illustrate each theory with real-life examples for a deeper understanding and better recall. Some theories may overlap and interconnect, so comprehending the unique elements of each is important.
