Psychological Terms – Anandamide
A naturally occurring neurotransmitter-like chemical in the brain that activates the same receptors influenced by cannabis-derived compounds.
It is involved in regulating mood, memory, appetite, and pain perception.
The term draws on Sanskrit roots meaning “bliss,” suggesting its association with rewarding and pleasurable subjective states.

Psychological Terms – Analytic Statement
A propositional form in which the truth is established by the logical relationship among its terms rather than by reference to external facts.
Because the predicate concept is already embedded within the subject concept, these statements are true by definition and are known a priori.
Examples include:
• “All triangles have three sides.”
• “All bachelors are unmarried.”
The denial of an analytic statement results in self-contradiction.
They are contrasted with synthetic statements, whose truth depends on observation.

Psychological Terms – Anamnesis
​Refers to recollection, especially the revival of past experiences or personal history.
The term can also describe an individual’s narrative account of the origin and development of a disorder, often gathered during evaluation or intake to support diagnosis.
In clinical practice, anamnesis helps chart symptom progression and contextual influences.
The adjective anamnestic refers to ease of recall or to memory traces that readily emerge.

Psychological Terms – Anamorphic
Describes an image that is intentionally distorted so that it appears normal only when viewed from a particular angle or via a specialized reflective surface (such as a cylindrical mirror).
Although the distorted figure may be difficult or impossible to decipher in its original orientation, the proper vantage point restores accurate proportions.
A notable example is the skull hidden in Holbein’s The Ambassadors (1533), which is visible only when viewed at a sharp angle.
This phenomenon illustrates perceptual transformation and visual reconstruction.

Psychological Terms- Anal Erotism 
Anal erotism refers to the early concentration of sexual pleasure (libido) on the anal region, especially during the developmental phase known as the anal stage. The child may derive gratification from stimulation associated with bowel movements.
In classical psychoanalysis, this phase contributes to later personality development, particularly traits associated with control, aggression, and orderliness.

Psychological Term — Anal -Expulsive Phase 
The anal-expulsive phase is the first part of the anal stage proposed by Karl Abraham. In this stage, a child gains pleasure from releasing feces, and linked aggressive impulses are expressed in destruction or disorder.
Later, development ideally progresses to the anal-retentive phase, when control and withholding become primary. Abraham suggested that the healthy transition between these sub-stages is essential to later forming loving and cooperative relationships.

Psychological Term — Analgesia 
Analgesia is the reduction or elimination of the sensation of pain. It may be induced medically—by drugs such as opioids or non-opioid painkillers—or produced psychologically through mechanisms such as hypnosis.
Analgesia differs from anaesthesia because general sensation (e.g., touch) may remain intact even when pain perception is reduced. The experience of analgesia provides insight into the brain’s capacity to modulate pain and the influence of attention, expectation, or dissociation on sensory processes.

Psychological Terms — Analgesic 
An analgesic is a medication or substance that reduces pain perception. Analgesics include multiple classes—from basic drugs like aspirin to opioid medications that act on endorphin receptors.
Analgesics are widely used clinically, and research into their effects helps illuminate pain pathways, placebo responses, and psychological meaning associated with pain relief.

Psychological Terms- Analogue 
An analogue is something judged comparable to another. In psychology and cognitive science, the term also describes a representational format in which properties of the representation resemble properties of what is represented—for example, the continuous relationship between positions on a dial and their real-world referents.
Chemical “analogues” also refer to compounds similar in composition, often differing by substitution of a molecular group. This term contrasts with digital or symbolic representation, which uses discrete codes rather than continuous relationships.

Psychological Terms - Analogies Test
​An analogies test is a type of cognitive assessment designed to measure reasoning ability by evaluating how well a person can recognize relationships between pairs of concepts. These items typically follow a structured format such as:A is to B as C is to ___
In this format, the test-taker must first understand the relationship between the first pair of words or symbols (A and B) and then identify which of the provided options completes the second pair (C and ___) using an equivalent relationship.
For example, consider the analogy:
Bird is to air as fish is to ___
Here, the correct answer is water, because both “bird → air” and “fish → water” represent natural environments for each creature.
More difficult analogies require deeper abstraction or knowledge. For instance:
C is to X as F is to… (M, U, L, V, or H)
The correct choice is U, because C and X are each three letters from opposite ends of the alphabet, and F and U are each six letters from opposite ends. This reflects the important feature of analogies: although more than one response may seem justifiable, only one correctly reproduces the specific logical rule linking the first pair.
Analogies tests are used widely in intelligence testing because they assess multiple cognitive skills simultaneously, including verbal comprehension, abstract reasoning, pattern recognition, and the ability to apply relationships to new stimuli. Because they rely on recognizing structure rather than recalling memorized facts, they are considered good indicators of higher-order reasoning.
These tasks also provide insight into how individuals categorize information, draw inferences, and transfer relationships across different domains—abilities that are central to problem-solving in both academic and real-world contexts.
