6. Object permanence
Explanation:
1. Trait
A trait has to do with something that its stable and enduring e.g. Self-esteem -a personality trait that deals with an individual's beliefs, emotions and behaviours.
2. Critical period
A critical period is defined as a window through which a system sustains an increased sensitivity to a certain stimuli so as to develop in a functional form.
3. Toxins
A toxin is a poisonous substance manufactured within living cells or organisms. It doesn't comprise of synthetic toxicants which are produced by artificial methods.
4. Determinism
Determinism is a theory that holds on to the belief that every event, moral choices e.t.d are totally controlled by previously existing causes. It basically preclude free will since it believes that humans cannot behave in certain ways otherwise than the way they do.
5. Continuum
