Main pathways of emotion generation
Physiology distinguishes two basic routes through which an emotional reaction originates and develops. They depend on the location of the source of the triggering signal.
- Endogenous pathway (internal). In this case, the emotion originates deep within the body, and its main drivers are current needs and motivation formed on their basis. The triggering mechanisms here are humoral (chemical substances in the blood) and neural stimuli. The process unfolds strictly "from within," primarily due to the activation of subcortical brain structures that react first to changes in the internal environment.
- Exogenous pathway (external). This mechanism is activated when an emotion becomes a response to the recognition of an external stimulus. The chain of reactions is as follows: first, the external stimulus affects receptors, then the signal is transmitted to the cerebral cortex for recognition and analysis, and only after that the corresponding emotional reaction is formed.
Physiological basis of goal-directed behavior
Any conscious human activity is built on physiological mechanisms of anticipation. The central link here is the action result acceptor (a concept proposed by the physiologist P.K. Anokhin).
It is this apparatus that allows the brain to pre-forecast the parameters of a future goal. Based on this mechanism, the so-called "optimistic goal-directed personality" is formed. A person anticipates in advance the positive emotions (for example, a sense of joy and satisfaction) that they will experience upon achieving the required result. This internal expectation of emotional reward serves as a powerful motivator: it compels the subject to actively strive for the intended goal and mobilize resources to overcome even the most complex obstacles along the way.
Psychophysiology of learning and motivation formation
The processes of goal setting and achieving results manifest most brightly and consistently at the stage of early learning and child rearing. The key element here is the reinforcement mechanism: any achievement of the goal, even the most minor one, is physiologically accompanied by a pronounced positive emotion.
Based on this mechanism, a most important principle of upbringing is formulated: it is necessary to teach a child to bring any started task to its logical conclusion so that the cycle ends with positive emotional reinforcement.
The development of the motivational sphere goes through three successive stages:
- External assistance. At the initial stage, the child cannot cope alone, and parents help them achieve the result.
- Realization. Over time, the child begins to independently realize all the "charm and beauty," that is, to experience deep pleasure from the very fact of satisfying their needs and successfully solving set tasks.
- Transformation. On the basis of regularly received pleasure from success, a persistent and long-lasting drive for complex types of activity—labor, art, and creativity—is formed.
Interrelation between the emotional sphere and personality
There is no one-sided dependence between emotions and the development of the human personality. This connection has a pronounced bidirectional character, where both components constantly influence each other.
First, emotional sensations themselves act as an "educator" of the personality. If a person regularly experiences a situation of success and the positive emotions accompanying it, a persistent goal-directedness and confidence in their actions are formed. Second, the reverse process occurs: as the personality is nurtured, matures, and is enriched with new experience, its emotions are refined. Emotional reactions become deeper, more differentiated, and more complex.
Briefly: answers to topical questions
Which neurotransmitters mediate the physiological mechanism of positive emotional reinforcement?
The physiological mechanism of positive emotional reinforcement is mediated by several neurotransmitters and neuropeptides.
- Serotonin — ensures learning processes based on emotionally positive reinforcement.
- Dopamine — acts as the main mediator in the brain's "reward systems".
- Endorphins — neuropeptides that also participate in the implementation of "reward system" functions.
- Endogenous opioid neuropeptides (enkephalins, endoethanols, endomorphins) — cause euphoria, activate the positive reinforcement system, and maintain emotional balance.
To avoid confusing the pathways: ENdogenous — ENergy from within (needs, subcortex). EXogenous — EXposure to the world (external stimulus, cerebral cortex).
