Q&A

• What are the mental health implications of internet usage?

  The internet is causing mental health issues by limiting our mental diet, decreasing cognitive flexibility, and promoting echo chambers. To improve mental health, it's important to engage with contrary opinions and spend less time on the internet.

• How is cognitive flexibility related to mental illness?

  Cognitive flexibility affects emotion regulation, addiction, and treatment outcomes. Its lack is correlated with various psychological issues and the rise in mental illness in society.

• How does brainwashing impact cognitive flexibility and stress responses?

  Brainwashing with our own beliefs can reduce cognitive flexibility and BDNF, leading to an inability to learn from mistakes. Meanwhile, stress mindset and psychological flexibility play a crucial role in shaping cognitive, emotional, and physiological responses to stress.

• What is the role of BDNF in internet addiction and mental health?

  Lower BDNF levels have been correlated with internet addiction. Traumatic events and stress can impact BDNF gene expression. BDNF is crucial for cognitive flexibility, resilience, coping with stress, and higher creativity. Moreover, it affects cognitive flexibility in adolescents and adult hippocampal neurogenesis.

• How does the internet affect cognitive flexibility?

  The internet often feeds the same content repeatedly, which can lead to cognitive inflexibility. Radical political beliefs have been linked to lower cognitive flexibility. Additionally, low levels of the brain chemical BDNF, crucial for cognitive flexibility and stress coping, can impact cognitive flexibility.

• What are the negative psychological impacts of echo chambers and brainwashing?

  Continuous exposure to the same ideas in echo chambers can lead to brainwashing, reinforcing existing beliefs and causing negative psychological impacts such as rising depression, anxiety, social anxiety, and loneliness.

• 00:00 The internet creates echo chambers by reinforcing existing beliefs, leading to brainwashing and negative psychological impacts such as rising depression and anxiety.
• 04:38 Exposure to a variety of stimuli is important for mental health but the internet feeds the same content repeatedly, leading to cognitive inflexibility. Radical political beliefs are linked to lower cognitive flexibility. Brain chemical BDNF is crucial for cognitive flexibility and coping with stress. Low BDNF levels affect cognitive flexibility in mice and human mental health.
• 09:38 The role of BDNF in internet addiction and adolescence is crucial. Lower BDNF levels are correlated with internet addiction. Traumatic events and stress are linked to BDNF gene expression. Cognitive flexibility is associated with resilience, less stress, and higher creativity. Cognitive inflexibility correlates with decreased resilience, higher stress, and poor performance in games like League of Legends. Adult hippocampal neurogenesis affects cognitive flexibility and reversal learning.
• 14:36 Brainwashing ourselves reduces cognitive flexibility and BDNF, leading to an inability to learn from mistakes, while stress mindset and psychological flexibility play a crucial role in shaping cognitive, emotional, and physiological responses to stress.
• 19:26 Mental illness is on the rise and correlated with cognitive flexibility. Cognitive flexibility affects emotion regulation, addiction, and treatment outcomes. Lack of cognitive flexibility leads to various psychological issues in society.
• 24:14 The internet is causing mental health issues by limiting our mental diet, decreasing cognitive flexibility, and promoting echo chambers. We need to engage with contrary opinions and spend less time on the internet to improve our mental health.
