Altered States of Awareness01:06

Altered States of Awareness

1.5K
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Implicit Personality Theories

682
Implicit personality theory explains how individuals make assumptions about the relationships between personality traits, behaviors, and character types. When people learn that someone possesses a particular trait, they tend to infer the presence of other related characteristics, forming a cohesive impression. This cognitive shortcut plays a crucial role in social interactions and interpersonal judgments.Central Traits and Their InfluenceSolomon Asch's seminal 1946 study highlighted the power...

Sedatives and Hypnotics: Overview

2.2K
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

2.2K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Sedatives and Hypnotics Drugs: Barbiturates01:20

Sedatives and Hypnotics Drugs: Barbiturates

1.5K
Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect.

Personality Disorders: Schizotypal and Histrionic

1.1K
Schizotypal personality disorder and histrionic personality disorder are two distinct psychological conditions classified under personality disorders, each characterized by unique behavioral patterns and social difficulties. Both disorders significantly affect interpersonal relationships and emotional well-being, leading to social isolation and frustration.

Area of Science:

  • Psychology
  • Clinical Hypnosis Research

Background:

  • Assessing hypnosis styles is crucial for understanding therapeutic efficacy.
  • Existing methods may lack comprehensive or standardized approaches.

Purpose of the Study:

  • To introduce and evaluate a novel system for assessing hypnosis style: the Feature-Based Coding System (FBCS).
  • To examine the interrater agreement, internal consistency, and construct validity of the FBCS.

Main Methods:

  • Videotaping 24 individual hypnosis sessions for coding using a previous system and the new FBCS.
  • Administering the Archaic Involvement Measure (AIM), Phenomenology of Consciousness Inventory (PCI), and Dyadic Interactional Harmony Questionnaire (DIH) to subjects and hypnotists.

Main Results:

  • The FBCS demonstrated good interrater agreement.
  • The Maternal-Paternal Axis construct within FBCS showed strong internal consistency (α = .95).
  • Findings supported the construct validity of the FBCS.

Conclusions:

  • The Feature-Based Coding System (FBCS) is a reliable and valid tool for assessing hypnosis styles.
  • Further large-scale studies are recommended to confirm the FBCS's utility and reliability.
