History of Study: From Mechanism to Subjectivity
Historically, physiological views on emotional experiences underwent significant changes. Researchers initially struggled with anthropomorphism—the uncritical attribution of human feelings and experiences to the animal world.
Following sharp criticism of this approach, scientific opinion swung to the opposite extreme. At a certain point, emotions were completely excluded from the study of animal behavior and experimental research. Some scientific schools attempted to reduce all living organism responses exclusively to mechanical reflexes triggered by external stimuli, ignoring the internal world.
However, the prominent physiologist Ivan Pavlov considered the total denial of the subjective world "nonsense." He emphasized that psychology, as a discipline formulating phenomena of the subjective world, is entirely legitimate and necessary. Human social and personal life is built upon this subjective foundation, and the task of proper science is to deeply analyze this aspect rather than ignore it.
Main Properties and Characteristics
The physiological and psychological profile of emotions consists of several fundamental characteristics:
- Totality and continuity. An emotional background is always present. It is practically impossible to isolate a human state that is not accompanied by subjective experiences. They permeate all levels of vital activity: from basic instinctive drives to the highest and most complex forms of social interaction.
- Connection with needs. Experiences are inextricably linked to behavior. They accompany both the emergence of numerous needs and the process and forms of their satisfaction. Any human action is tied to self-perception and a formed attitude toward the external world.
- Intensity dynamics. The expression of experiences can fluctuate across a vast range. The minimal level is observed during certain phases of physiological sleep or under anesthesia. The maximum point is affect, a critical state in which an individual completely loses the ability to control their actions.
- Clinical significance. Emotions are closely tied to physical status. A patient's general well-being and specific ailments always go hand in hand with characteristic emotional sensations, which is important to consider during history-taking and status evaluation.
Functions of Emotions
The biological significance of subjective experiences is immense. First, they act as sensitive indicators that constantly scan and reflect:
- Internal bodily states and current needs.
- External environmental impacts (manifesting most acutely in the social sphere during interpersonal interactions).
- The subject's general attitude toward themselves and reality.
Additionally, emotions perform critical evaluative and prognostic functions. They allow the organism not only to rapidly assess its current physiological state and environmental factors, but also to anticipate these impacts in the future in order to proactively adapt behavior.
Classification: Polarity of Experiences
Traditionally, all subjective human experiences are divided into two polar groups depending on their valence and effect on behavior:
- Negative emotions. Signal distress, unsatisfied needs, or threat. These include: fear, hunger, anger, sadness, disappointment, hatred, disgust.
- Positive emotions. Arise upon successful satisfaction of needs or favorable prognosis. This group includes: joy, pleasure, love, delight, pride, satisfaction.
