Thanks Carcass on the answers.
Could you please let me know why "states" is the answer for 3rd blank and not "characteristics" ?

Breaking down the sentence

The renowned psychologist B. F Skinner's particular brand of behaviorism

He was the exponent of a specific line of thinking about the behavior science

which he called "Radical" behaviorism, unlike less austere behaviorisms,did not accept private events such as thinking, personal perceptions, and unobservable

That means his theorist was austere. Therefore, the emotions were NOT accepted

Now is a key part of the entire story

in a casual account of an organism's (ii) _______

i. e. casual account means we must have specific reasons and NOT at a random mode of an organism's behavior

presumably a self-aware one reporting such (iii) _______ as an observer of itself.

maybe someone reports such STATES as he or she being the observer itself

We are talking about psychology, behave.....and state. G at a closer look is out of scope

We do have a state of mind because is part of our psychology, behavior.

G is another thing in another context

In certain scenarios, we DO NOT have a behave at a random but specific. This scenario per se or reported is a state, a condition of our psychology. NOT a characteristic

G is when you have blue eyes or black hair. here we do have a state


Hope my explanation was useful
