Psychological Terms – Amitriptyline
Amitriptyline hydrochloride is a prominent tricyclic antidepressant (TCA) used to treat major depression and sometimes eating disorders such as anorexia nervosa or bulimia nervosa when depression is present. It is also prescribed for certain forms of nerve-related pain.
The drug works by blocking the reuptake of monoamine neurotransmitters, particularly serotonin and norepinephrine, increasing their concentration at central nervous system synapses. Amitriptyline is sold under names such as Amitril, Elavil, Endep, Laroxyl, Saroten, and Triptafen.

Psychological Terms – Ammon’s Horn
Ammon’s horn is another name for the major part of the hippocampus, a brain region crucial for learning, memory, and spatial navigation. Together with the subiculum and the dentate gyrus, it forms the hippocampal formation.
The name derives from the Egyptian deity Ammon, often depicted with ram’s horns—resembling the curved hippocampal structure. Damage to this area is strongly associated with amnesia, especially the inability to form new memories.

Psychological Terms – Amnesia
Amnesia refers broadly to memory loss, usually affecting declarative memory more than procedural memory. The loss may involve failure to recall past events or difficulty creating new long-term memories.
Major related forms include:
The word derives from Greek, meaning “without memory.”

Major related forms include:
- Anterograde amnesia – difficulty forming new memories
- Retrograde amnesia – inability to recall previously stored memories

Psychological Terms – Amnesic Syndrome
Amnesic syndrome refers to the same condition as amnestic disorder, involving substantial impairment in forming or retrieving long-term memories, while other cognitive capacities may remain relatively intact.

Psychological Terms – Ambilingual
An ambilingual person can speak two languages with equal fluency and competence, displaying what linguists call balanced bilingualism. This level of proficiency implies a high degree of cognitive flexibility and mental adaptability, as ambilingual individuals often switch seamlessly between linguistic systems. Psychological studies link ambilingualism to enhanced executive function, improved working memory, and delayed cognitive decline in old age. The term derives from Latin ambi- (“both”) and lingua (“tongue”), reflecting dual linguistic mastery.

Psychological Terms – Ambiguity Aversion
Ambiguity aversion describes the tendency to favor options with known probabilities over those involving uncertainty. This bias was first illustrated by the Ellsberg paradox, where participants prefer to bet on a known chance of success rather than an unknown one, even when expected outcomes are identical. Psychologically, ambiguity aversion highlights the role of risk perception, cognitive bias, and emotional regulation in decision-making. It has broad applications in behavioral economics and cognitive psychology, where it demonstrates how humans prioritize psychological comfort over logical probability. Neuroimaging studies link this aversion to heightened activity in the amygdala and anterior insula, regions associated with anxiety and uncertainty processing.

Psychological Terms – Ambiguity Tolerance
Ambiguity tolerance refers to an individual’s ability to cope with uncertainty, complexity, or conflicting information without undue anxiety or avoidance. People high in ambiguity tolerance demonstrate open-mindedness, creativity, and flexible thinking, while low tolerance is associated with dogmatism and authoritarian personality traits. In psychological assessment, ambiguity tolerance predicts adaptability and innovation, particularly in problem-solving, leadership, and intercultural competence. It is also crucial in psychotherapy, where clients must tolerate uncertainty about emotional change and self-discovery.

Psychological Terms – Ambiguous Figure
An ambiguous figure is a visual pattern—such as the Necker cube, duck-rabbit illusion, or Rubin’s vase—that can be perceived in more than one distinct way. The observer’s perception alternates between these interpretations, illustrating how top-down cognitive processes and expectations influence perception. Ambiguous figures are often used in studies of Gestalt psychology, which explores how the mind organizes sensory input into coherent forms. They demonstrate that perception is not purely passive but actively constructed by the brain, shaped by context, memory, and attention.

Psychological Terms – Ambivalence
Ambivalence refers to the coexistence of opposing emotions, thoughts, or impulses toward a single object or person—such as simultaneous love and hate. Introduced by Eugen Bleuler in 1910 as a key feature of schizophrenia, the term was later adopted by Sigmund Freud to describe conflicting feelings in interpersonal relationships, particularly within psychoanalysis. Ambivalence illustrates the complexity of emotional life, where opposing drives can coexist and create psychological tension. In modern psychology, it is studied within the contexts of attitude conflict, cognitive dissonance, and attachment theory.
