Avoidance, not the original bite, keeps a composite technician's dog phobia alive, and the NU671 Unit 1 post explains why through Mowrer's two-factor account and then states its limits. Searches like "nu 671 unit 1 assignment example", "nu671 unit 1 sample" and "nu671 unit 1 example" land here.
What a finished NU671 Unit 1 discussion board post looks like
Four paragraphs and a reply, citing three sources. Paragraph one describes the technician's pattern in behavioral terms: which calls he declines, what he feels approaching a gate, and the relief when a customer confirms the dog is shut away. Paragraph two sets out Mowrer's two-factor theory, first proposed in 1947, as two distinct processes: the bite conditioned the fear, while each avoided gate removes anxiety and so reinforces the avoiding. Paragraph three draws the consequence. Because he never stays near a calm dog long enough for the feared outcome to fail to arrive, the old association is never updated. Paragraph four qualifies all of it with Rachman's (1977) observation that many phobias have no conditioning event at all, so the account fits this man better than it fits every case.
How a NU671 Unit 1 example is structured
Behavior leads and theory follows. The opening paragraph uses observable acts and reported feelings only, so the later claim about reinforcement has something concrete to attach to. Acquisition and maintenance get separate sentences with separate verbs, because running them together is how most accounts lose the point that the second process no longer needs the first. The relief he describes on hearing that a dog is locked indoors is identified as the reinforcer, quoted once and afterward referred to rather than repeated. Rachman's pathways enter as a limit on the theory, not a rival to it, and the account names plainly which part of the theory that limit touches. The last sentence points toward treatment without choosing one: whatever helps him must let the fear be tested rather than escaped. One reply follows, questioning a classmate's use of the word trigger.
Pattern before principle
Declined calls, a tight chest at garden gates and relief when a dog is shut inside open the post. Stating the pattern first gives the theory specific behavior to explain instead of a diagnosis to decorate.
Two processes, two verbs
The bite conditioned the fear; the avoiding reinforces itself. Keeping acquisition and maintenance in separate sentences shows that the second process has run on its own for twenty years without any help from the first.
Relief named as the reinforcer
His own words about relief, quoted once, identify what strengthens the avoidance. Negative reinforcement is defined in a clause and applied at once, which keeps the term from floating free of the case it is meant to explain.
One route among several
Rachman's three pathways, conditioning, observation and information, show that plenty of fears begin without any bite. The post keeps its claim to this man and presents the two-factor account as one origin story among several, not the only one.
A reply about the word trigger
The classmate reply asks whether an anxiety described as triggered by a memory is driven by the memory or by present cues. It proposes one question that would tell the two apart and does not dispute where the classmate ended up.
Where marks go in NU671 Unit 1
Credit on this board depends on separating how the fear began from what sustains it, and posts that tell only the origin story, the bite and the lingering memory, address something the prompt never raised. Also weak is the maintenance account that names avoidance but never says why escaping should strengthen anything; negative reinforcement left undefined leaves the mechanism implied. Graders comment when two-factor theory is offered as the settled cause of all phobias, since indirect and non-associative pathways are well described. A post that jumps to exposure therapy in its second paragraph has skipped the explanatory work this unit exists for. Minor deductions go to confusing negative reinforcement with punishment, to citing one textbook for everything, and to a reply that repeats the classmate's point in new words.

Which condition does your Unit 1 board ask about: a phobia, a compulsion, a low mood that outlasted its cause? Put that question beside the NU671 rubric and whatever case the section provided. A first post returns free in 24-48h, written to those instructions, separating onset from maintenance and closing on a response to a single classmate.
NU671 Unit 1 questions, answered
Is two-factor theory still accepted?
As a description of how avoidance maintains fear, largely yes; as a complete account of how fears begin, no. Rachman showed that observation and information also produce fears, and later work on inhibitory learning refined how extinction operates. Presenting the theory with its date and its limits reads to a grader as currency rather than as disagreement with the reading.
Should the post propose a treatment?
Only as a pointer. Persistence, why a problem continues, is the usual subject of the opening board here, and therapy selection arrives later in the term. One sentence noting what any effective treatment would need to change, such as letting the feared outcome be tested, connects the explanation forward without turning the post into a plan nobody requested.
Can the example be a personal fear?
Check the prompt first, since some sections ask for a composite or a supplied case. If personal material is allowed, the same structure works: pattern, acquisition, maintenance, limit. Keep the detail proportionate, because a board is a shared space and the analysis earns the credit, not the disclosure. Any sample prepared for you uses a composite by default.
