Emotion: Arousal, Behavior, and Cognition

Emotion, or affect, is a multifaceted psychological process distinct from reasoning or knowledge. Emotions are influenced by various internal and external factors that impact individuals differently. Early 20th-century theories on emotion delved into the differentiation between the physiological and cognitive aspects of emotional experiences. While some theories suggested that these experiences occurred sequentially, others proposed that they happened simultaneously. Specific theories underscore the necessity of cognitive interpretation for emotional experiences. According to the facial-feedback hypothesis, facial expressions play a pivotal role in shaping emotional experiences, aligning with the notion that the physiological component of emotion precedes cognitive appraisal. These theories highlight that emotions encompass three main components: bodily arousal, expressive behaviors, and conscious feelings. For instance, bodily arousal can manifest as increased heart rate or sweating, expressive behaviors may include smiling or frowning, and conscious experience involves feelings of happiness, sadness, or fear. By examining emotions through physiological, behavioral, and cognitive lenses, researchers can understand how these elements interact and contribute to our overall emotional experiences.

Summary of Emotion Theories

*Specific names of theories of emotion will be outside the scope of the AP Psychology Exam.

Understanding Basic Human Emotions

Researchers have pinpointed a number of fundamental human emotions that are universally acknowledged across diverse cultures. Emotions such as anger, disgust, sadness, happiness, surprise, and fear seem to be commonly felt across different societies. Nevertheless, studies investigating the universality of emotions have yielded diverse outcomes, indicating that cultural influences may shape how emotions are expressed and understood. These emotions are typically classified according to two primary dimensions: valence, which determines whether an emotion is positive or negative, and arousal, which signifies the intensity of the emotion.

Connection Between Emotional Arousal and the Autonomic Nervous System

Emotional arousal plays a significant role in activating our body's autonomic nervous system, which is responsible for regulating involuntary bodily functions. Different emotions trigger distinct physiological responses in our bodies. For instance, feelings of fear can lead to a decrease in skin temperature, while emotions like anger can cause an increase. When we experience various emotions, our sympathetic nervous system, also known as the fight or flight response, becomes activated to prepare us for action. This activation results in the release of stress hormones such as epinephrine (adrenaline) and norepinephrine (noradrenaline), mobilizing the body for a response. Once the sympathetic nervous system has done its job, the parasympathetic system takes over to help us return to a state of calmness.

Understanding Emotions and Brain Responses

One of the significant brain structures that play a key role in how our brains respond to emotions is the amygdala, a vital part of the limbic system that is responsible for regulating emotions, memory, and motivation. The amygdala is intricately connected to various brain regions through neural pathways and is particularly involved in the emotional response to fear in humans. Brain scans have revealed that the amygdala becomes active when we encounter threatening stimuli such as images, faces, or sounds. Different emotions activate distinct brain circuits and also influence specific areas of the brain's cortex. For instance, experiencing negative emotions like repulsion can lead to increased activity in the right prefrontal cortex, while positive feelings stimulate the left frontal lobe. Individuals with upbeat personalities often exhibit higher left frontal lobe engagement, portraying characteristics of increased energy, persistent motivation, and goal-oriented behavior.
