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 – 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.

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.

KembaraXtra-Psychology – Bohr Effect
The Bohr effect describes the physiological process by which hemoglobin releases oxygen more readily in tissues with higher concentrations of carbon dioxide and lower pH levels. This mechanism ensures that active tissues receive increased oxygen supply. Although primarily a biological concept, it illustrates adaptive physiological regulation.

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.
