Q & A

Why do astronauts have difficulty communicating non-verbally in space?

Astronauts in space face challenges in non-verbal communication because the weightlessness causes their bodily fluids to make their faces puffy, which makes facial expressions harder to read.

How can Botox potentially improve mood?

Botox can improve mood not by smoothing wrinkles, but by easing depression. This is due to the Facial Feedback Hypothesis, which suggests that facial expressions can help regulate emotions. A Botox injection in the forehead may lessen depression by making it difficult to frown.

What is considered rude in the Philippines that is common in the US as a 'come here' gesture?

The 'come here' gesture, which is common in the US, is considered extremely rude in the Philippines and could potentially lead to legal trouble.

What is the Facial Feedback Hypothesis and how does it relate to emotions?

The Facial Feedback Hypothesis is the theory that our facial expressions can help regulate our emotions. For example, smiling can lift one's mood, even if they are not genuinely happy, while scowling can lower it.

Who is Paul Ekman and what is his view on facial expressions?

Paul Ekman is an emotion expert who believes that facial expressions are culturally universal. According to him, people from different cultures can discern the same basic emotions—happiness, sadness, disgust, anger, fear, and surprise—just by looking at someone's face.

What are the basic human emotions identified by Carol Izard?

Carol Izard, an American psychologist, identified ten distinct basic human emotions present from infancy: joy, surprise, sadness, anger, disgust, contempt, shame, fear, guilt, and interest or excitement.

What is the 2-dimensional model of emotional experience?

The 2-dimensional model of emotional experience describes emotions as a combination of valence (good or bad) and arousal (excited or not excited). This model helps to understand the spectrum of emotions and how they can be positioned on this scale.

How does stress affect the body's physiological functions?

Stress can affect the body's physiological functions by triggering the sympathetic nervous system and the fight or flight response. It can increase blood pressure, heart rate, and cholesterol levels, and can also impact the digestive system by altering digestion and secretions.

What is the relationship between chronic stress and heart disease?

Chronic stress is a significant risk factor for heart disease because it can lead to increased blood pressure, heart rate, and cholesterol levels. Stress can also affect the liver's ability to filter fat and cholesterol from the blood, potentially contributing to heart disease.

How does the autonomic nervous system interact with the body's systems during stress?

The autonomic nervous system, which includes the sympathetic and parasympathetic systems, regulates many basic body functions. During stress, the sympathetic system activates the body's fight or flight response, while the parasympathetic system helps to calm the body down. Both systems interact with the enteric nervous system, which can explain the link between stress and digestive problems.

What are some of the psychological and biological effects of chronic negative emotions like pessimism and depression?

Chronic negative emotions like pessimism and depression can lead to a variety of psychological and biological effects, including an increased risk of chronic diseases, higher rates of digestive, respiratory, circulatory, and infectious diseases, and a potential reduction in life expectancy due to their impact on health and well-being.
