Types of Motivations

For medical students2 min readUpdated 2026-10-10

Motivation is an active state of the nervous system that drives humans or animals to perform goal-directed actions to satisfy their needs. In normal physiology, all motivations are generally divided into two large groups: innate biological and acquired social.

Main GoalSatisfaction of leading needs to preserve the individual and ensure the survival of the species.
DominanceAt any given moment, a single need that is most crucial for survival predominates.
HierarchySocial motivations are built upon a powerful foundation of innate biological drives.
RegulationIn a socialized individual, the satisfaction of basic needs is regulated by appropriate time and place.

Biological Motivations

Biological motivations are also referred to in physiology as primary drives, lower, simple, or primary motivations. These are evolutionarily ancient mechanisms, the main goal of which is to satisfy leading biological needs, which is absolutely essential for preserving the life of the individual and continuing the species.

The main types of biological motivations include:

Each of these motivations has a strict physiological basis—a specific shift in the body's internal environment. For example, the food craving is triggered by a decrease in nutrient levels in the blood. Thirst arises as a response to an increase in plasma osmotic pressure. Temperature regulation motivation forms upon any significant change in body core temperature, and sexual motivation is directly linked to an increase in sex hormone levels in the circulating blood.

Social Motivations

Social motivations are considered higher, or secondary, motivations. Unlike biological ones, they are not innate, but rather built upon biological foundations and develop progressively. This process occurs through the active interaction of the developing organism with its environment, parents, and other individuals. In humans, the formation of such motivations occurs exclusively under the powerful influence of the social environment.

Three key factors influence the formation of human social motivations:

  1. Environmental exposure;
  2. Learning processes;
  3. Memory mechanisms.

Characteristic examples of social motivations include the drive for education, professional mastery, and an affinity for art, literature, and domestic organization. All of these are formed through social upbringing and are strictly determined by existing moral standards, laws, and legislation inherent to a specific socioeconomic system.

Interaction of Motivations and the Principle of Dominance

In real life, humans and animals regularly encounter situations where they may experience multiple different needs simultaneously. In such cases, the principle of dominance of needs comes into effect.

According to this rule, at any given moment, only the need that is most critical for the survival of the individual or its species right then will dominate. As a result, this dominant drive completely takes over the control of the body and constructs an integrated behavioral act directed exclusively toward its immediate satisfaction.

It is important to note the complex interplay between biological and social factors. Social factors can significantly alter the initial nature of basic biological motivations. In a socialized human, strict regulation develops during ontogenesis: the satisfaction of biological needs (such as food or sexual drives) becomes tightly regulated. Unlike in animals, these processes in humans are adapted to socially acceptable contexts of time and place.

Mnemonic

To remember physiological triggers of basic motivations, use the mnemonic «PIG-TEMP»: PI-N (Nutrients/Hunger), G-Hormones (Sexual), TEMP-Osmotic pressure/Temperature.

Frequently asked questions

Which brain structures serve as the centers for forming biological motivations?

The centers for forming biological motivations are located in the hypothalamus, which plays a leading pacemaker role in organizing dominant motivation. Motivation formation is a systemic process involving several brain structures:

  • Hypothalamus — the site of the primary origin of motivational excitation.
  • Limbic system and reticular formation — receive primary projections, enhance excitation, and ensure its irradiation.
  • Frontal cortex (Cortex frontalis) — receives ascending information, programs activity, executes decision-making, and provides the efferent output for goal-directed behavior.
Which physiologist formulated the doctrine of dominance?

The doctrine of dominance was formulated by Aleksey Ukhtomsky. The stage of afferent synthesis operates according to the principle of dominance; elevated excitability of higher autonomic centers creates a dominant focus that absorbs other stimuli.

Which specific hormones drive the onset of sexual motivation?

Sexual motivation (libido) is driven by the accumulation of sex hormones—androgens and estrogens—in the blood. The leading hypothalamic centers are primarily influenced by the following hormones:

  • Androgens (specifically testosterone) — stimulate sexual drive; in males, testosterone is produced almost continuously and shapes sexual behavior.
  • Estrogens — together with androgens, determine sexual drive in females, peaking at ovulation during the late follicular phase.

Almost all endocrine glands also participate in the execution of sexual behavior.

Which motivations are called primary?

Biological motivations are referred to as primary (or lower). These include hunger, thirst, fear, aggression, as well as sexual and parental drives aimed at the survival of the individual and the species.

What serves as the physiological basis for thirst?

The physiological basis of thirst (fluid motivation) is an increase in osmotic pressure within the body's internal environment.

What is the essence of the principle of dominance of needs?

The principle states that when multiple needs are present simultaneously, the one most critical for the organism's or species' survival at that moment always predominates, shaping current behavior.

How does the social environment affect human biological needs?

The social environment and upbringing can modify the nature of basic motivations. As a result, the satisfaction of biological needs in humans is strictly regulated by social norms and restricted to specific times and places.
