KembaraXtra-Psychology – Bruxism
Bruxism is the habitual grinding or clenching of teeth, which may occur during wakefulness or during Stage II non-REM sleep. It is often associated with stress, anxiety, or sleep disorders and can lead to dental damage, jaw pain, and headaches. Bruxism illustrates the interaction between psychological tension and motor activity.

KembaraXtra-Psychology – Brute Force Algorithm
A brute force algorithm is a problem-solving method that systematically examines every possible solution before selecting the optimal one. While feasible for small-scale problems, brute force approaches become impractical for highly complex tasks such as the travelling salesman problem or chess, due to the enormous number of possible combinations. This concept highlights computational limits in both artificial intelligence and human cognition.

KembaraXtra-Psychology – Brunswik Faces
Brunswik faces are simplified schematic drawings of human faces used in perceptual and cognitive research. Developed by psychologist Egon Brunswik, these stylized faces allow researchers to systematically vary features such as eye spacing, nose size, and mouth curvature. By manipulating these variables, psychologists can study perceptual discrimination, categorization, and the processes involved in social judgment.

KembaraXtra-Psychology – Brujería
Brujería refers to a form of folk healing or spiritual practice found in Spanish-speaking Caribbean and southern United States communities. Closely related to rootwork or folk magic traditions, it often involves rituals, herbal remedies, and spiritual beliefs intended to influence health, relationships, or fortune. In psychological contexts, such practices are studied as examples of culturally embedded belief systems that influence perception, coping, and mental health.

KembaraXtra-Psychology – Bruce Effect
The Bruce effect refers to a phenomenon observed in mice in which a recently mated female fails to maintain pregnancy when exposed to the scent of an unfamiliar male. The effect is triggered by pheromones present in the urine of the strange male, which disrupt prolactin secretion and prevent implantation of the fertilized ovum. It was first described by British reproductive biologist Hilda Margaret Bruce in 1959. This phenomenon illustrates the powerful role of olfactory cues and pheromonal communication in reproductive biology.P

KembaraXtra-Psychology – Bromocriptine
Bromocriptine is a dopamine agonist medication derived from ergot alkaloids. It mimics the action of dopamine in the brain and is commonly used in the treatment of Parkinson’s disease, where dopamine deficiency contributes to motor symptoms. It is also prescribed for certain hormonal conditions such as amenorrhoea and infertility because it suppresses prolactin secretion from the anterior pituitary gland. By targeting dopamine receptors, bromocriptine demonstrates the close relationship between neurochemistry and both motor and endocrine regulation.

KembaraXtra-Psychology – Brightness Enhancement
Brightness enhancement is the phenomenon whereby a light flickering at approximately 10 hertz appears brighter than the same light presented steadily. This effect is thought to result from increased activity in retinal ganglion cells at certain flicker frequencies below the critical flicker fusion threshold.

KembaraXtra-Psychology – Brightness Masking
Brightness masking is a form of visual masking in which a bright flash of light interferes with the perception of another visual stimulus. The intense luminance disrupts normal visual processing, reducing visibility of the target stimulus.

KembaraXtra-Psychology – Bril
A bril is a unit used to quantify perceived brightness. In this system, a luminance level of one millilambert is arbitrarily assigned a value of 100 brils. Although not commonly used in everyday measurement, the unit reflects early attempts to standardize subjective brightness perception in psychophysical research.

KembaraXtra-Psychology – Brightness Contrast
Brightness contrast refers to the perceptual phenomenon in which the brightness of an area appears different depending on the luminance of surrounding areas. It is closely related to lightness contrast and illustrates how visual perception depends on contextual comparison rather than absolute luminance.
