Introduction to Motivation and Emotion

Introduction to Motivation and Emotion

Motivation is a multifaceted process that drives behavior toward fulfilling various physiological or psychological needs. This process involves initiating, guiding, and maintaining specific actions influenced by internal and external factors. For example, when someone feels hungry while watching television, hunger is a motivator, prompting the individual to get up, walk to the kitchen, and find something to eat. In this instance, hunger initiates and sustains the behavior necessary to meet the...

Physiology of Emotion

Physiology of Emotion

The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...

Functional Brain Systems: Limbic System

Functional Brain Systems: Limbic System

The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Empathy

Empathy

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Cognitive Theories: Schachter-Singer Theory of Emotion

Cognitive Theories: Schachter-Singer Theory of Emotion

Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences physiological...

Organization of the Brain

Organization of the Brain

The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Summary

Researchers explored emotional processing, focusing on brain circuits that evolved for survival. Studies used electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) to examine autonomic and somatic reflexes in response to emotional stimuli.

Area of Science:

Neuroscience
Psychophysiology
Emotion research

Background:

Emotional expressions are rooted in evolutionarily ancient motivational brain circuits.
These circuits evolved to ensure survival by mediating responses to environmental and memorial cues.
Understanding these circuits is key to understanding human emotion.

Purpose of the Study:

To review psychophysiological and neuroscience studies on emotional processing.
To focus on reflex reactions and neural mechanisms of emotional expression.
To explore the brain's motivational circuits underlying human emotion.

Main Methods:

Review of studies from the University of Florida's Center for the Study of Emotion and Attention (CSEA).
Assessment of reflex physiology (autonomic and somatic) of emotion.

Utilized electroencephalography (EEG) and functional magnetic resonance imaging (fMRI).

Studied emotional responses to picture perception, memory imagery, reward, and punishment.

Main Results:

Identified specific neural structures and functional circuits mediating emotional expression.
Demonstrated how motivational circuits tune sensory systems and mobilize organisms for action.
Linked brain activity to appetitive and aversive cue processing, underlying positive and negative affects.

Conclusions:

Expressed emotions are fundamentally based on evolutionarily conserved motivational brain circuits.
These circuits play a critical role in survival by mediating adaptive behavioral responses.
EEG and fMRI provide valuable insights into the neural underpinnings of human emotion.
