Presumably, it explains principles of human thawt
Alas you presume wrong !
I have no factual information
qua what the hi school students are studying in the way of psychology.
Human psychology is the study of human behavior.
I am skeptical that all
psychologists r behaviorists and only that.
If that were true, then forensic psychology 'd be impossible.
That has to do with the defendant's state of mind: his beliefs (which r thawts),
and whether he is capable of understanding,
which again addresses his ability to think and how he does it.
For instance, the infamous M'Naghten
case was decided upon
the basis of what the defendant believed; that saved him
from being hanged.
If psychology were confined to observation of behavior as u said,
then inquiry into neuroses and psychois woud be impossible.
That is not the prevailing state of affairs.
I do not deny the existence of behaviorists.
"Thinking" has been a problem area for the application
of the objective scientific method to which psychologists aspire.
I can live with that.
Where thinking can be divided up into "experimental areas" such as "memory", "learning" and "problem solving", a plethora of statistical results have been generated which may or may not be applicable to "real life". No psychologist would claim this is a unified field of study. Psychopathology ("weird thinking") can be fun with its competing early theorists like Freud, but the fact is most "therapies" are pretty equivalent in success rates which often boil down to a communicative rapport between therapist and subject. Discounting medication, which crudely alters brain chemistry, there are as many "cures" by parish priests as psychoanalysts.
"Psychology" as an academic subject purports to teach experimental techniques, statistical processing and the history of the subject in terms of competing theories. No great insights into how "thinking works" are likely to be forthcoming.
I stand by what I said (for now, anyway).
I think I vaguely discern some emotional investment
in this from u.
