In psychology, neophobia is defined as the persistent and abnormal fear of anything new. In its milder form, it can manifest as the unwillingness to try new things or break from routine. Mild manifestations are often present in young children (who want the small portion of the world that they "know" to remain constant) and elderly people (who often cope using long established habits and don't want to learn "new tricks").
Neophobia is also a common finding in aging animals, although apathy could also explain, or contribute to explain, the lack of exploratory drive systematically observed in aging. Researchers argued that the lack of exploratory drive was likely due, neurophysiologically, to the dysfunction of neural pathways connected to the prefrontal cortex observed during aging.
Was vast al bekend, maar stond hier nog niet tussen volgens mij.
