KembaraXtra-Psychology – Body Dysmorphic Disorder
Body dysmorphic disorder is a mental health condition characterized by excessive preoccupation with perceived flaws in physical appearance that are either minor or unobservable to others. Individuals may engage in repetitive behaviors such as mirror checking or seeking reassurance, often experiencing significant distress and functional impairment. The disorder reflects distorted body image processing and is related to obsessive–compulsive spectrum conditions.

KembaraXtra-Psychology – Blood–Brain Barrier
The blood–brain barrier is a selectively permeable membrane that protects the brain by regulating which substances in the bloodstream can enter neural tissue. Formed by tightly joined endothelial cells, it prevents toxins and pathogens from reaching the brain while allowing essential nutrients to pass. This barrier is critical for maintaining stable neural functioning but also complicates drug delivery to the brain.

KembaraXtra-Psychology – Blocking
Blocking is a phenomenon in classical conditioning in which prior learning about one stimulus prevents learning about a new stimulus when both are presented together. If a conditioned stimulus has already been associated with an unconditioned stimulus, introducing a second stimulus alongside it does not produce additional learning about the new cue. Blocking illustrates that conditioning depends on prediction error rather than mere pairing.

KembaraXtra-Psychology – Blind Spot
The blind spot is the region on the retina where the optic nerve exits the eye, creating an area devoid of photoreceptors and therefore insensitive to light. Although this gap exists in each eye, individuals are typically unaware of it because the brain fills in missing visual information based on surrounding context. The blind spot demonstrates how perception is constructed rather than passively recorded.

KembaraXtra-Psychology – Blackout
A blackout refers to a temporary loss of memory for events that occurred during a period of consciousness, most commonly associated with acute alcohol intoxication but also occurring in certain neurological conditions. During an alcohol-induced blackout, individuals may appear alert and capable of functioning but later have no recollection of events due to disruption of memory consolidation processes in the hippocampus. Unlike loss of consciousness, blackout involves preserved awareness at the time but impaired encoding into long-term memory.

KembaraXtra-Psychology – Bottom-Up Processing
Bottom-up processing refers to perception driven primarily by sensory input rather than prior knowledge or expectations. Information flows from lower-level sensory receptors upward to higher-level cognitive processing centers. This process allows novel stimuli to be interpreted based on raw data before contextual interpretation occurs.

KembaraXtra-Psychology – Body Language
Body language includes nonverbal behaviors such as posture, gestures, facial expressions, and eye movements that convey emotional states and interpersonal attitudes. Often operating unconsciously, body language complements or contradicts spoken communication and plays a critical role in social interaction and impression formation.

KembaraXtra-Psychology – Boomerang Effect
The boomerang effect occurs when a persuasive attempt produces the opposite of the intended attitude change. Instead of being convinced, the recipient strengthens their original position. This may result from perceived manipulation, high ego involvement, or psychological reactance, highlighting the complexity of persuasion processes.

KembaraXtra-Psychology – Body Schema
Body schema is the dynamic internal representation of the position and movement of one’s body parts in space. It integrates proprioceptive, tactile, and visual information to guide coordinated action. Disturbances in body schema may occur following neurological injury and can lead to impaired motor control or altered self-perception.
