What would the relation between
perception and skill have to be, if
it were to constitute a legitimateinstance of cognitive penetration?

Ifa skill is learned through practice and is
related to perception in an explanatorily
relevant way, then such a relationship
constitutes a genuine case of cognitive
penetration.

Is perception more like playing
the violin or digestion?

The issue is NOTwhetherperception is accompanied bycognition.
The issue IS whether thequalitative core of a perceptual
event is influenced, impacted,structured, or constituted bycognition.

Cognitive Penetrability:
If a system is cognitively penetrable
then the function it computes is
sensitive, in a semantically coherent
way, to the organisms goals and beliefs,that is it can be altered in a way that
bears some logical relation to what a
person knows.
-Zenon Pylyshyn, Is vision continuous with
cognition?, p. 343.

TWO ISSUES:
1) Are allcognitive
statespropositionalstates likegoals, beliefs,thoughts, andknowledge?
2) IfNO, then how
can we make
sense of a a
logical relationtoor semantic
coherence with
nonproposition-albut cognitive
states?

Why think there are
nonpropositional, cognitive states?
Knowing-how v. knowing-that

Ryles Regress
The consideration of propositions isitself an operation the execution ofwhich can be more or less intelligent,
less or more stupid. But if, for anyoperation to be intelligently executed,a prior theoretical operation had firstto be performed and performedintelligently, it would be a logical
impossibility for anyone ever to breakinto the circle.

Propositional rules can never
provide the specificity requiredto govern acting en situ.
Particular rules are not rules at all.

How can perceptual processing bear a
semantically coherent or logical relation
to a cognitive state?

Learning and cognitive content
The reason learning is so central tointelligentbehavior, to the behavior ofpeople, is that learning is the process inwhich internal indicators are harnessed to
output and thus become relevantasrepresentations, as reasonsto theexplanation of the behavior of which they arepart. It is in the learning process thatinformation-carrying elements get a job to do
because of the information they carry andhence acquire, by means of their content, arole in the explanation of behavior.

What is learned through practice?
Attention and control: that which is responsible for themanner or style in which a skill is instantiated.

Cognitive Penetrability of
Perception by Skill
If that part of skill which is developed
through practice (i.e., that aspect of
skill that is responsible for the
manner or style in which a skill is
performed) is related to early
perceptual processing in an
explanatorily relevant way, then wehave a legitimate case of the cognitive
penetrability of perception by skill.
