Introduction to Behaviour

Behaviour is the interaction between internal and external stimuli, leading to a reaction.
Behaviour encompasses a wide variety of human activities, including physical and psycho-social actions, reflexes, instincts, learned responses, and facial expressions.
All observable and measurable human activities are considered behaviour.

What is Stimulus?

A stimulus is any factor that causes detectable changes in the human organism.
Stimuli received by sense organs result in perception.
Examples of stimuli include light waves (perceived by the eye), sound waves (perceived by the ear), taste (perceived by the tongue), and touch (perceived by the skin).

Reactions

Reactions are the changes in physical or mental structure resulting from stimuli.
These changes can vary in type and severity, depending on the nature and intensity of the stimulus.
Reactions can be categorized as overt (observable actions like speaking, walking) or covert (internal experiences like thoughts, feelings).
Reactions can also be categorized as conscious or unconscious, and voluntary or involuntary.

Understanding Behaviour

Every behaviour has a reason.
To understand and predict behavior, one must consider several factors:
- Biological characteristics (age, gender, intelligence, interests)
- Past experiences (upbringing, education, events)
- Current internal state (hunger, tiredness, mood)
- Environmental conditions (temperature, noise level, social context)

This quiz explores fundamental concepts related to human behaviour and stimuli. It covers the types of behaviour, the nature of stimuli, and how reactions occur as a result of environmental factors. Test your understanding of these vital psychological topics.
