How Our Facial Expressions Reveal Our True Feelings

Emotional states refer to the feelings and moods experienced by an individual, such as depression, anxiety, or stress, which can be influenced by negative events, personal characteristics, or the environment. These states are closely tied to one's beliefs about themselves and the world around them.

Psychologists have tried to identify the different types of emotions that people experience. A few different theories have emerged to categorize and explain the emotions that people feel.

According to one theory, emotions exist across two dimensions: the first being a dimension of valence leading from positive to negative, and the other being a dimension of activation/arousal ranging from energy-conserving to active. This approach allows the visualization of discrete emotions within a two-dimensional space.

Another theory suggests that there are six basic emotions: happiness, sadness, disgust, fear, surprise, and anger. However, a 2017 study suggests that there are far more basic emotions than previously believed, identifying 27 distinct categories of emotion.

Emotions play a critical role in how we live our lives, from influencing how we engage with others in our day-to-day lives to affecting the decisions we make.

Facial expressions might not be reliable indicators of emotion

Section title: Facial expressions might not be reliable indicators of emotion

Facial expressions are often perceived as conveying meaning, but their origin and significance are not always clear. Some experts have hypothesised that facial expressions are reliable indicators of emotion, but a new study contradicts this hypothesis.

According to the study, conducted by scientists at The Ohio State University, endeavours to detect or define emotions based on a person's facial expressions were often wrong. The study analysed the kinetics of muscle movement in the human face and compared those muscle movements with an individual's feelings.

Aleix Martinez, a professor of electrical and computer engineering at The Ohio State University, said, "Everyone makes different facial expressions based on context and cultural background. And it's important to realise that not everyone who smiles is happy. Not everyone who is happy smiles."

Martinez also noted that people sometimes smile out of obligation to social norms, and that some companies have begun developing technology to recognise facial muscle movements and assign emotion or intent to those movements. However, Martinez criticised these technologies, stating that they are "lacking" and that there is "no way" to determine things like whether a student is paying attention in class or whether a customer is satisfied with a purchase.

The study concluded that it takes more than facial expressions to detect emotion correctly. Martinez explained that when a person experiences emotion, their brain releases peptides that change the blood flow and blood composition, which in turn changes the colour of the face.

In one experiment, Martinez showed participants a picture of a man with his mouth open in an apparent scream, and his face bright red. When the image was cropped to display only the man's face, participants thought he looked super annoyed or mad. However, when the full image was shown, it became clear that the man was a soccer player celebrating a goal.

In conclusion, the research group's findings indicate that people—including hiring managers, professors, and criminal justice experts—should consider more than just a facial expression when evaluating another person. While Martinez expressed belief in developing computer algorithms that try to understand social cues and a person's intent, he emphasised that such technology will never be 100% accurate and that deciphering a person's intent goes beyond their facial expression.

Happiness is a pleasant emotional state

Happiness is a complex and multifaceted emotion that is often defined as a pleasant emotional state. It is characterised by feelings of contentment, joy, gratification, satisfaction, and well-being. Happiness is associated with positive life experiences, such as achieving goals, spending time with loved ones, or engaging in enjoyable activities. However, it can also arise spontaneously without any apparent external cause.

Research has shown that individuals who experience higher levels of happiness tend to have better physical and mental health, stronger social relationships, and greater resilience in the face of adversity. Happiness has been linked to a variety of positive outcomes, including increased longevity and greater marital satisfaction. It is often expressed through facial expressions such as smiling, body language such as a relaxed stance, and an upbeat, pleasant tone of voice.

While happiness is considered one of the basic human emotions, the things we think will make us happy are heavily influenced by our culture. For example, pop culture often emphasises that buying a home or having a high-paying job will result in happiness. However, the reality is often much more complex and individualised.

Happiness is a subjective experience and can vary from person to person. What one person considers happiness may be different from another's interpretation. It is also dynamic and can fluctuate over time and across different situations.

Emotions like happiness are influenced by three key elements: the subjective experience, the physiological response, and the behavioural response. The subjective experience refers to the individual's unique interpretation of the emotion, which can vary even among people experiencing the same emotion. The physiological response involves physical reactions in the body, such as increased heart rate or a lurch in the stomach, which are often regulated by the sympathetic nervous system. The behavioural response is how the emotion is expressed, such as through facial expressions or body language.

Overall, happiness is a pleasant emotional state that has been linked to positive outcomes and well-being. It is a fundamental part of the human experience and can be influenced by a variety of factors, including cultural norms and individual interpretations.

Sadness is a transient emotional state

Sadness is something that all people experience from time to time. In some cases, people can experience prolonged and severe periods of sadness that can turn into depression.

Fear is a powerful emotion that can play a role in survival

The experience of fear can be positive or negative, depending on the person. Some people are adrenaline seekers and enjoy thrilling situations, while others avoid fear-inducing situations at all costs.

Fear can also be a symptom of mental health conditions such as panic disorder, social anxiety disorder, phobias, and post-traumatic stress disorder (PTSD).

The human brain has evolved to increase our chances of survival, and fear is a critical component of this survival intelligence.

Anger can be a particularly powerful emotion

Anger can be a positive and useful emotion if expressed appropriately. It can help clarify your needs in a relationship and motivate you to take action and find solutions to things that are bothering you. However, it can also become a problem when it is excessive or expressed in unhealthy, dangerous, or harmful ways. Uncontrolled anger can quickly turn to aggression, abuse, or violence, and can lead to arguments, physical fights, and self-harm. It can also have both mental and physical health consequences, such as increased anxiety, high blood pressure, headaches, and digestion and skin problems.

Anger is one of the six basic emotions that, according to psychologist Paul Eckman, are universally experienced in all human cultures. These emotions are happiness, sadness, disgust, fear, surprise, and anger. However, a 2017 study identified 27 distinct categories of emotion, suggesting that emotions exist along a gradient and are deeply interconnected.
