I am sorry (truly) that, briefly, I am "back", but Psychology is so messed up that occasionally I have to more expressly comment on yet another aspect, especially if it is seen as basic or fundamental.
ISSUE: Should psychologists define "learning" as :
"a relatively permanent change in behavior as a result of experience" [(with no guidance on, or demarcation of, the "experience" involved)]? ("Behavior change" may also be ill-defined.)
What? Are researchers supposed to assume that anything THEY see as "experiences" can be taken to mean "distinct in processing" all-equal-experiences FOR LEARNING, and for these experiences to simply be AS THEY SEE them??
How about : Learning : a relatively permanent change in behavior patterns* due to the association (or disassociation) of distinct certain, well-specified aspects of experience (or documented types of experience), clearly corresponding to aspects of the present (or once present) observable environment and/OR clearly and properly having their foundation in behaviors directly related to such **. [ Often learning, most notably includes: that for useful representation and understanding, for species-typical adaptation -- though this last part can be (and can "safely" be) implicit, so the definition can end at : "... related to such" . ]
If psychologists want to grow-up and be real scientists, the latter definition is what they MUST use (AND they MUST do any research necessary in order to use it !) Otherwise (as most psychologists now seem to see for themselves): the situation in their field is hopeless. (I have presented a solution for understanding behaviors, consistent with this opinion and with that better definition of learning -- click my name, and seek and you shall find.) Psychology concepts are simply (STILL) not good enough for a continuously developing science (which is a sure aspect of any real science).
* FOOTNOTE: If you find the patterns (which, in a biological organism WILL BE THERE), this at least somewhat demarcates or specifies the real behaviors. The fact that psychology rarely speaks in terms of behavior patterns, itself, indicates how far "off base" past and present psychology has been and IS.
** FOOTNOTE: Other than these aspects of overt behavior patterns (and corresponding environmental aspects), including those that are foundational, there is only associative and discriminative learning -- terms which, if taken to mean ONLY what they indicate, are ALREADY well-defined.
Being able to well-understand this definition involves knowing the nature of our Memories, and using that to contextualize much behavior (the content foremost in our memories changes with development, of course). If you think this definition is incorrect, know that it relies ONLY on hypotheses which are testable.
