“Behavior is anything an individual does that can be observed in some way.”

Human behavior refers to all observable actions performed by individuals, including what we do (physical actions), what we say (verbal behavior), as well as our facial expressions and bodily gestures. Behavior serves a purpose, either to accomplish a task or to communicate a message. Since human behavior is observable, it can be seen or heard in various forms.

Human behavior can be broadly categorized into three types:

1. Physical Actions
2. Verbal Behavior
3. Facial Expressions and Bodily Gestures

1. Physical Actions

Physical actions refer to behaviors performed through the use of the body or its parts. These actions are goal-directed and are carried out to accomplish specific tasks or outcomes.
Examples include shaking hands with a friend, assisting someone in lifting a heavy object, slapping, walking, eating, writing a letter, completing a questionnaire, or breaking glass. Each of these actions reflects observable physical movement directed toward a particular purpose.

2. Verbal Behavior

Verbal behavior includes all forms of spoken communication. It involves the use of words with specific meanings to interact and communicate with others. Verbal exchange constitutes a major part of daily human interaction.

For instance, greetings such as “Hello” or “Hi,” questions like “How are you?” or “Where are you going?”, commands such as “Come here,” “Go there,” or “Get out,” and statements like “I was waiting for you” or “I was late for the meeting” all represent verbal behavior.

The primary purpose of verbal behavior is communication. Its meaning is influenced not only by the choice of words but also by tone, pitch, and context in which they are spoken.

3. Facial Expressions and Bodily Gestures

Human interaction also occurs through non-verbal channels such as facial expressions and bodily gestures. These forms of behavior play a crucial role in expressing emotions and intentions without the use of words.

For example, smiling indicates approval or happiness, while frowning expresses disapproval or displeasure. Facial expressions can communicate a range of emotions, including joy, sadness, anger, fear, surprise, excitement, and confusion. These emotional signals are generally universal and easily interpreted by others.

Bodily gestures further enhance communication. For instance, a parent may invite a child to come closer by opening their arms with palms facing forward, which the child understands and responds to. Similarly, a speaker may use hand movements to emphasize key points during a presentation. The V-sign made by a winner is commonly interpreted as a symbol of victory. Thus, facial expressions and bodily gestures constitute an essential and meaningful part of human behavior.

   OVERT AND COVERT BEHAVIOUR

Most behaviorists and psychologists view human behavior as an observable phenomenon. According to this perspective, only those actions that can be directly observed or measured are considered behavior. This includes physical actions, verbal behavior, and facial or bodily gestures, as these can be seen or heard. From this standpoint, internal mental processes that are not directly observable are not classified as behavior.

However, other psychologists argue that human behavior encompasses both observable actions and internal, unobservable processes. They emphasize that mental activities such as thinking, memory, cognition, perception, and information processing are integral components of behavior. To clearly distinguish between these two dimensions, the terms overt behavior and covert behavior are used.

Overt behavior refers to observable and measurable actions, including physical movements, spoken language, facial expressions, and bodily gestures. These behaviors can be directly seen or heard by others.

In contrast, covert behavior refers to internal psychological processes such as thinking, remembering, interpreting information, and decision-making. These processes occur within the mind and cannot be directly observed by others, although they can often be inferred from overt behavior.

It is important to recognize that overt behavior is frequently influenced by covert mental processes. In other words, observable actions are often the outward expression of internal cognitive and emotional activity. Thus, what individuals say or do is largely shaped by what is occurring within their mind.

Example

For instance, a student sitting in an examination hall may appear calm and focused (overt behavior), while internally they are thinking about how to solve difficult questions, recalling learned concepts, and managing anxiety (covert behavior). Similarly, a person smiling and greeting others politely (overt behavior) may internally be feeling happy, confident, or socially motivated, which guides their outward expression.
