KembaraXtra-Psychology – Cacogeusia
Cacogeusia is the perception of an unpleasant or distorted taste in the absence of an appropriate stimulus. It may occur as a hallucination or illusion and has been reported in epilepsy, medication side effects, and certain psychiatric conditions. Disturbances in taste perception demonstrate the close integration of sensory processing and neurological function.

KembaraXtra-Psychology – Cachexia
Cachexia refers to severe physical debilitation and weight loss associated with chronic illness. It involves muscle wasting, fatigue, and metabolic disturbances and is often seen in advanced cancer, chronic infections, or systemic disease. Although primarily medical, cachexia has psychological implications, including depression, reduced quality of life, and cognitive decline associated with prolonged illness.

KembaraXtra-Psychology – BZ Gas
BZ gas (benzilic acid gas) is a chemical incapacitating agent with atropine-like properties. When inhaled, it produces confusion, hallucinations, disorientation, and physical impairment. Its psychological effects can be profound, temporarily disrupting perception, cognition, and behavior. It is classified among chemical incapacitating agents rather than lethal weapons.

KembaraXtra-Psychology – Cachinnation
Cachinnation is loud, raucous, or inappropriate laughter occurring without a suitable emotional cause. It is sometimes observed in certain psychiatric conditions, particularly disorganized (hebephrenic) schizophrenia, where emotional expression may be incongruent with context. The symptom illustrates disturbances in affect regulation and social appropriateness.

KembaraXtra-Psychology – Body Image
Body image refers to an individual’s perception, thoughts, and feelings about their physical appearance. It encompasses both cognitive evaluations and emotional responses, which may or may not align with objective reality. Body image is shaped by cultural standards, media exposure, personal experiences, and developmental factors, and plays a significant role in self-esteem and identity.

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 – 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.
