Anxiety: Overview

1.1K
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Theory of Romantic Attachment in Adulthood

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Generalized Anxiety Disorder

779
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Panic Disorder

843
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Hazan and Shaver's Attachment Styles

537
Attachment theory, developed initially to explain infant–caregiver bonds, has been extended to illuminate patterns of intimacy in adult romantic relationships. Psychologists Cindy Hazan and Phillip Shaver proposed that the attachment styles observed in infancy form a framework for how individuals approach emotional closeness and conflict in adulthood. These attachment styles—secure, avoidant, and anxious—are linked to enduring patterns of behavior and emotional regulation in...

Social Anxiety Disorder01:28

Social Anxiety Disorder

574
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Summary

High-trait anxiety impairs attention, showing alpha band frequency changes during tasks. Low-trait anxious individuals maintain stable cognitive resources, unlike high-trait anxious individuals.

Area of Science:

  • Cognitive Neuroscience
  • Psychophysiology

Background:

  • Trait anxiety is linked to attentional impairments.
  • Alpha band frequency differences exist between low- and high-trait anxious individuals.

Purpose of the Study:

  • Investigate alpha band frequency differences in trait anxiety during rest and cognitive tasks.
  • Examine how trait anxiety affects attentional resource allocation.

Main Methods:

  • Quantitative electroencephalography (qEEG) recordings in human participants.
  • Measured alpha band frequency during resting state and an Eriksen Flanker Task.
  • Compared individuals with low vs. high trait anxiety.

Main Results:

  • High-trait anxious individuals showed alpha band desynchronization from rest to task.
  • Low-trait anxious individuals maintained stable alpha band frequency.
  • Suggests differential attentional resource management based on trait anxiety.

Conclusions:

  • High-trait anxiety requires mobilizing attentional resources for task performance.
  • Low-trait anxiety is associated with stable cognitive resource availability.
  • Alpha band frequency dynamics reflect trait anxiety's impact on attention.
