Psychology Terms – afterimage
A sensory experience, particularly a visual image, that continues after the stimulus has terminated, also referred to as a primary afterimage, or one that emerges subsequent to a primary afterimage. The initial visual afterimage resulting from brief exposure to a bright stimulus is termed a *Hering image and is typically a *positive afterimage, wherein the dark regions of the original image remain dark and the light regions remain light, generally manifesting in the same colors as the original stimulus, though occasionally appearing colorless, and lasting merely a fraction of a second. The ensuing Purkinje image is a complementary afterimage, with the hues of the original stimulus manifesting in nearly complementary colors in the image. It exhibits greater persistence than the Hering image but typically vanishes when the gaze is redirected; however, it can frequently be momentarily reinstated by blinking. The third afterimage is positive and referred to as a *Hess image. The effects can be illustrated by allowing one's eyes to acclimate to darkness for a minimum of 15 minutes, followed by activating a camera's electronic flash—cautioning against direct gaze with dark-adapted eyes—or by momentarily illuminating a bright light.

Psychology Terms - Affricate
An affricate is a complex consonant spoken sound characterized by the articulation of a plosive immediately followed by a fricative at the same point of articulation. English possesses two affricate phonemes: the initial and final sounds in "church," representing the voiceless affricate, and the initial and final phonemes in "judge," denoting the voiced affricate.

Psychology Terms – Affordance
A word introduced in 1977 by American psychologist James Jerome Gibson (1904–79) to denote a resource or support supplied by the environment to an organism, enabling the organism to operate in a specific manner. Affordances include a surface that provides physical support, an appetizing substance that offers the option to consume, and the positioning of an outstretched hand that presents the possibility of a handshake.

Psychology Terms - Affirming the consequent
. In conditional reasoning, the fallacious argument that asserts, from a hypothetical premise of the form If p then q, that because q is true, p must also be true. For instance, considering the proposition If the thieves accessed the premises through the front entrance, they must have forced the lock; nonetheless, it is erroneous to deduce that their act of forcing the lock necessitates their entry by the front door.

Psychology Terms - Affirming the antecedent
In conditional reasoning, correctly arguing from a hypothetical assertion structured as If p, then q; since p is true, it follows that q is true. For instance, considering the proposition If the burglars accessed the premises by the front door, then they must have forced the lock; thus, it is logical to conclude that their entry by the front door necessitated the forcing of the lock.
