Role of Emotions in Mental Activity

For medical students2 min readUpdated 2026-10-10

Human mental activity is inextricably linked to subjective emotional experiences. Emotions act as crucial markers that continuously reflect our current needs and the influence of environmental factors capable of satisfying those needs.

Primary RoleReflection of one's own needs and environmental factors for their satisfaction.
ForecastingFormation of anticipation regarding future emotions based on past experience.
EmergenceThe appearance of a new biological or mental need triggers negative emotions.
NavigationEmotions continuously evaluate the internal state of the subject and external influences.

Emotional Basis of Thought Processes

Any cognitive and thought processes do not occur in isolation—they always carry an emotional coloring. Mental activity is grounded in subjective emotional experiences.

From a physiological standpoint, emotions are not merely a "mood." They perform a strictly defined task, reflecting two key components of vital activity:

  1. The emergence and presence of the subject's own needs.
  2. The impact of various environmental factors that are potentially capable of satisfying these arising needs.

Main Functions of Emotions

Subjective experiences serve as a universal evaluation tool. The key functions of emotions come down to the continuous analysis of the most critical aspects of interaction between the organism and the environment:

Dynamics of Emotional States

Any need in the process of its development goes through specific stages, each having its own specific emotional coloring. This dynamics is universal for both simplest biological and highest psychological drives.

  1. Stage of Need Emergence. When a need is just forming, it signals a disruption in equilibrium or a deficit. This state is predictably accompanied by negative emotions. These negative experiences serve as a powerful motivational push for action, forcing the subject to seek ways to solve the problem.
  2. Stage of Need Satisfaction. The successful fulfillment of a need and elimination of the deficit are always accompanied by various positive emotions. They play the role of reinforcement, consolidating the successful behavioral strategy.

Probabilistic Emotional Forecasting

The organism is capable not only of reacting to stimuli "here and now" but also of looking into the future. Due to accumulated experience (situations of repeated need satisfaction in the past), a person develops the ability to anticipate future positive emotions.

A key mechanism of this process is the inclusion of the emotional component in the memory mechanisms of the action result acceptor. The subject anticipates the result and the associated positive experiences in advance.

However, the system works both ways: in certain specific situations, the organism similarly predicts the emergence of negative emotions to avoid undesired actions. Ultimately, a complex system of probabilistic emotional forecasting of all mental activity is formed.

Summarizing the above, it can be argued that emotions function as peculiar "information bearings." They remain in a state of constant activity, continuously evaluating both the subject's current internal state and the nature of external environmental impacts.

Mnemonic

The 4 functions of emotions can be remembered by the formula "4 Appraisals": Need, Environment, Others, Satisfaction (NEOS). Emotions evaluate WHAT we need, WHERE we are, WHO is around, and IF the goal was achieved.

Frequently asked questions

Which central nervous system structures are part of the limbic system responsible for emotional formation?

The limbic system responsible for emotions includes phylogenetically older cortical areas, the neocortex, and specific nuclei. Key structures include:

  • Hypothalamus (Hypothalamus) — the central hub of autonomic and endocrine regulation.
  • Septum (Septum) — an area associated with pleasure centers.
  • Amygdalar bodies (Corpus amygdaloideum) — formation of fear and aggression.
  • Hippocampus (Hippocampus) — memory, its emotional coloring, and spatial orientation.
  • Cingulate gyrus (Gyrus cinguli) — regulation of behavior and autonomic functions.
  • Entorhinal area.
  • Dentate gyrus.
  • Parahippocampal gyrus.
  • Mammillary bodies.
  • Fornix (of brain) and Commissure of fornix.
  • Anterior commissure.
  • Indusium griseum.
What is the essence of P.K. Anokhin's biological theory of emotions?

P.K. Anokhin's biological theory of emotions views the evolutionary and adaptive contribution of emotions to the activity of living creatures. Emotions are inextricably linked with all stages of the functional system (afferent synthesis, decision making, action result acceptor, efferent synthesis). Emotion is determined by the ratio of the subject's dominant need to the achieved result. A positive emotion sanctions search success, while a negative one arises in the absence of a result, prompting the subject to overcome obstacles.

How is P.V. Simonov's need-informational theory of emotions formulated?

P.V. Simonov's informational theory of emotions is formulated as follows: emotion is the brain's reflection of two factors: the actual need and the probability of its satisfaction.

Why does the emergence of a new need accompanied by negative emotions?

The appearance of a need implies a deficit (biological or psychological). The negative emotion serves as a signal of this discomfort and physiologically forces the organism to seek ways to eliminate it.

What is probabilistic emotional forecasting?

It is the ability of the psyche, based on past experience (repeated satisfaction of needs), to anticipate what emotions will arise as a result of certain planned actions.

What is the essence of the "information bearings" metaphor?

Emotions are compared to radars or bearings because they continuously and in parallel scan the person's internal state and the nature of external environmental impacts, guiding mental activity.
