Classical and operant conditioning article

What is conditioning?

Conditioning is a type of learning that links some sort of trigger or stimulus to a human behavior or response. When psychology was first starting as a field, scientists felt they couldn’t objectively describe what was going on in people’s heads. However, they could observe behaviors so that’s what they focused on in their experiments. The major theories about learning come from the conclusions drawn from these experiments. 


Operant Conditioning




Behaviorism: Emphasizes the study of observable behaviors and events and the predictable role of environment in causing behavior
Type of learning in which a person repeats a behavior that has been reinforced or ceases a behavior that has punished.

Operant Conditioning
Reinforcement: stimulus followed by behavior that increases the probability the behavior will be repeated. – Positive – Negative
Punishment: stimulus followed by behavior which decreases the probability that the behavior will be repeated. – Positive : Introducing an aversive event – Negative: Withdrawing a positive event

VERBS

A transitive verb is one that requires a direct object to finish its meaning.
Example: He (subject) plays (transitive verb) guitar (direct object).

An intransitive verb is one that does not need a direct object to complete its meaning.
Example: She (subject) laughs and smiles (compound intransitive verb).

Linking verbs—those that join a sentence subject to its complement—are likewise intransitive. Common linking verbs are become, seem, appear, feel, look, taste, smell, sound, and be. Subject complements for linking verbs will be adjectives, nouns, pronouns, possessive pronouns, or adverbs of time or place.

Examples: They (subject) seem (linking verb) joyful (adjective complement).
She (subject) is becoming (linking verb) a superb musician (noun complement).
The winner (subject) is (linking verb) you (pronoun complement).

Some verbs can function as either transitive or intransitive depending on their context.
Examples: When I need some light exercise, often I walk (intransitive).
When I need some light exercise, often I walk (transitive) the dog (direct object).

Other verbs that can be either transitive or intransitive are run, provide, enter, read, and call.

A Closer Look at Sentence Objects

Becoming proficient with transitive and intransitive verbs further includes knowing how they function with direct and indirect objects.

With transitive verbs, an indirect object appears between the verb and the direct object. You can spot a word or phrase as an indirect object by determining if it can follow the direct object with a prepositional phrase that begins with to, for, and occasionally of:

Sentence: The teacher gave the students (indirect object) homework (direct object).
Proof: The teacher gave homework (direct object) to the students (receiving prepositional phrase).

Transitive verbs that often allow indirect objects are give, make, tell, show, bring, send, sell, and offer.

Intransitive structures can at times be more tricky, often because they appear transitive but aren’t because of understood omission in context.
Examples: The inmate escaped the prison.
They left the party.

In the first example, the inmate didn’t escape the prison as a direct action to the object. He escaped from the prison, an intransitive context. The word from is omitted because it’s understood.

In the second sentence, they didn’t leave the party in terms of setting something down in a transitive context (e.g., left a dessert). They left from the party, an intransitive context. The word from is once again omitted because it’s understood.

With these principles in mind, we recognize how direct and indirect objects work in transitive and intransitive structures to add color and clarity.
Examples:
1) Please bring (transitive verb) me (indirect object with omitted to) the book (direct object). Including me conveys the book is destined for me instead of another person.

2) Could you grab (transitive verb with auxiliary could) me (indirect object with omitted for) another beer (direct object)? Once again we use an indirect object to communicate destination.

3) My feet are really aching (present progressive intransitive verb) me (reflexive pronoun operating as an indirect object with omitted to). While many would argue this is more colloquial speech than proper grammar, our deconstruction reveals the parts’ identities.

4) The following sentence applies both transitive and intransitive structures: The inmate escaped (intransitive verb) the prison (prepositional object with omitted from) and left (transitive verb) the warden (indirect object) a note (direct object).

By understanding how verbs are classified and related to the rest of the sentence, you’ll do more than write grammatically. You’ll also ensure that together your words will move as high-performance vehicles instead of as putt-putt wagons that meander through long and winding courses.
