Definition
Refers to sound energies having a frequency above the human hearing range. The highest frequency that the human ear can detect is approximately 20 thousand cycles per second (20,000 Hz).
Attachment bonds have been proposed to underlie a variety of social relationships, for example, parent–infant, filial, and pair (male–female) bond formation. These are all typically characterized by preferential proximity seeking and all involve a response to separation. These forms of attachment appear to be common to many species including humans, suggesting that the neural basis can be investigated in animal models. Emerging evidence suggests that the biology of attachment in its many forms may also be similar across species.
