“Niche picking” and “sxarr 1983” refer to a theoretical model in developmental psychology concerning heredity–environment interaction (gene–environment correlation), published in 1983 by psychologists Sandra Scarr and Kathleen McCartney. *Your “sxarr” is presumed to be a typo for psychologist “Scarr.” Explains “niche selection,” a central concept in this theory. Overview of the theory Scarr and McCartney proposed a Gene-Environment Correlation model in human development in which “genes direct the environment an individual experiences.” Children are said not merely to passively accept given environments, but to select and construct environments (niches) suited to their own genetic traits (phenotype). The 3 stages of gene–environment correlation This 1983 model explains that children's engagement with their environment changes through the following 3 stages as they grow. 1. Passive correlation (Passive) • Period: Infancy and early childhood • Characteristics: parents transmit genes to children and also provide an environment based on their own genetic tendencies. For example, musically talented parents fill their home with instruments, and children naturally grow up in that environment. 2. Evocative correlation (Evocative). • Period: Childhood and similar periods (decreases somewhat with age). • Characteristics: Children's genetic characteristics and behavior (phenotypes) elicit specific responses from others. For example, an always-smiling, active child induces favorable engagement from adults, resulting in a more stimulating, social environment. 3. Active correlation = “niche selection” (Active / Niche picking) • Period: Adolescence and adulthood onward (becomes most dominant with growth). • Characteristics: As people become more independent and their range of activity expands, they actively select and create specific environments (niches) that most comfortably fit their genetic temperament and abilities (genotype). For example, someone with a genetic tendency toward introversion and a love of reading will, as they grow, choose environments such as libraries, quiet clubs, or research careers. The conclusions suggested by this theory Scarr & McCartney's (1983) theory rejected extreme environmental determinism claiming “environment shapes humans completely.” It presents an important developmental-psychology perspective: as humans grow, they actively select “niches” in which they can realize their genetic potential to the fullest.
