Psychological Responses to Stress01:20

Psychological Responses to Stress

479
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Introduction to Stress and Lifestyle01:27

Introduction to Stress and Lifestyle

512
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Stress and Mental Health

770
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...

Longitudinal Research

13.1K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

General State of Stress01:21

General State of Stress

596
The general state of stress within a material can be accurately depicted using a stress tensor. This tensor encapsulates the internal forces distributed within a material subjected to external forces or deformations.
Specifically, consider a tetrahedral element where one face, labeled XYZ, is perpendicular to the line OA, and the remaining faces align with the coordinate axes with point O as the origin. At any point, such as point O, the stress tensor can be used to determine the stress...

Components of Stress01:23

Components of Stress

496
Stress analysis under multiple loading conditions is intricate, necessitating a comprehensive grasp of normal and shearing stresses. Consider a small cube at point O, subjected to stress on all six faces, visible or not. Normal stress components σx, σy, σz act perpendicularly to the x, y, and z axes. Shearing stress components τxy and τxz are exerted on faces perpendicular to these axes.
Interestingly, the hidden cube faces also experience these stresses, equal and...

Area of Science:

  • Digital well-being research
  • Human-computer interaction
  • Psychological impact of technology

Background:

  • Internet use is integral to modern life, affecting well-being.
  • Existing research on internet use and stress is limited, often relying on self-reports.
  • Both positive and negative associations between internet use and stress have been previously observed.

Purpose of the Study:

  • To investigate the associations between specific internet usage patterns and stress levels.
  • To explore how different contexts of internet use (how, where, when, by whom) relate to stress.

Main Methods:

  • A seven-month longitudinal study involving 1490 German internet users.
  • Combined fine-grained URL-level web browsing data with sociodemographics and monthly stress measures.
  • Utilized linear mixed models and a conceptual framework to analyze contextual dimensions of internet use.

Main Results:

  • Increased time on social media, online shopping, and gaming correlated with higher stress.
  • Time spent on productivity and news websites was associated with lower stress.
  • Specific findings include positive associations for shopping (mobile/desktop) and negative associations for productivity (mobile) and news usage (mobile/desktop).

Conclusions:

  • Internet use is context-dependent in its association with stress.
  • Identified behavioral markers can inform the development of tools for self-monitoring and self-moderation of online behaviors.
  • These tools aim to enhance individual well-being and potentially reduce strain on mental health services.
