Psychological Concepts

Definition: An Electroencephalogram (EEG) is a diagnostic procedure used to measure and record the electrical activity in the brain. Overview: EEG is a non-invasive test performed by placing small, metal electrodes on the scalp to detect and record the brain’s electrical patterns. Purpose: The main purpose of an EEG is to evaluate and diagnose various […]

Definition of Electrodermal Response (EDR) Electrodermal Response (EDR), also known as Galvanic Skin Response (GSR), is a physiological measure that assesses the conductance of the skin in response to emotional or autonomic arousal. Overview EDR measures the changes in electrical conductance of the skin, particularly in relation to the secretion of sweat from the sweat

Electrodermal Activity (EDA) Electrodermal Activity (EDA) refers to the changes in the electrical properties of the skin in response to various physiological and psychological stimuli. It is also commonly known as galvanic skin response (GSR) or skin conductance response (SCR). EDA is a non-invasive method used to assess the activity of the sweat glands on

Definition of Electroconvulsive Therapy (ECT) Electroconvulsive Therapy (ECT) is a medical procedure that involves the application of an electric current to the brain to induce controlled seizures. It is primarily used in the treatment of severe mental illnesses such as major depression, bipolar disorder, and sometimes schizophrenia. Application of Electric Current The procedure involves the

Electrocardiograph An electrocardiograph is a medical device used to record the electrical activity of the heart over a period of time. It is commonly known as an EKG or ECG machine. This non-invasive procedure helps diagnose various heart conditions by capturing the heart’s electrical impulses, which are then displayed as waves or tracings on a

Electrocardiogram (ECG) or EKG: An electrocardiogram (ECG) or electrocardiograph (EKG) is a diagnostic test that measures the electrical activity of the heart. It is a non-invasive and painless procedure that provides valuable information about the heart’s rhythm and electrical conduction system. Electrical Activity: The heart’s electrical activity is responsible for coordinating the contraction and relaxation

Definition Electrical Stimulation of the Brain (ESB) refers to a medical technique that involves the application of electrical currents to specific regions or structures within the brain. By doing so, it aims to modulate neuronal activity, excite or inhibit neuronal firing, and manipulate brain circuitry to study brain function or alleviate certain neurological disorders. Uses

Definition: Electric Stimulation of the Brain refers to the application of electrical currents to specific areas of the brain with the intent of modulating neural activity and studying various cognitive, behavioral, or therapeutic effects. Overview: Electric Stimulation of the Brain, also known as brain electrostimulation or cerebral electrical stimulation, involves the use of electrical currents

Electric Shock Method The Electric Shock Method is a therapeutic technique used in the field of psychiatry and psychology to treat certain mental health conditions. Description This method involves the controlled administration of electric shocks to the brain, also known as electroconvulsive therapy (ECT). It is primarily used in cases where other treatments such as

Electra Complex: The Electra complex is a psychoanalytic theory proposed by Sigmund Freud that refers to a daughter’s subconscious sexual desire for her father, and associated feelings of rivalry or jealousy towards her mother. This complex arises during the phallic stage of psychosexual development, typically between the ages of 3 and 6 years old. Subconscious
