Choose MRCPsych Mentor or SPMM according to the teaching and question practice you need, not because another candidate's overall score looks impressive. When the recurring problem is confusing neighbouring concepts, first build a contrast card: name both ideas, state the decisive difference and test it with a new example.
This article is published by iatroX and includes iatroX among the resources discussed. As checked on 13 September 2026, MRCPsych Mentor and SPMM advertise psychiatry examination preparation. Their public offers establish relevance, not that their teaching formats or private question collections are identical.
Why a definition card sometimes fails
A definition card asks whether you recognise a term. A contrast card asks whether you can distinguish it from the alternative you keep selecting. If you repeatedly confuse two concepts, learning each definition in isolation may leave the boundary between them unclear.
Start with your last few genuine errors. Record the concept you selected and the concept the explanation supports. Do not copy the commercial question. Look for repeated pairings: the same two ideas may appear in different topics or in different wording.
Give the pair a working title such as "what is removed versus what happens to the behaviour". A title that describes the discriminating task is more helpful than "psychology revision". You can then find out whether the mistake is terminology, mechanism or application.
An original contrast: negative reinforcement and punishment
The OpenStax account of operant conditioning, checked on 13 September 2026, distinguishes reinforcement by an increase in behaviour and punishment by a decrease. Positive and negative describe adding or removing a stimulus, not whether the outcome is morally good or bad.
Use an original, non-clinical example. A trainee repeatedly checks an online task list because completing a task removes a persistent reminder. In this fictional account, that removal makes the checking behaviour more likely. The important facts are the removal of a stimulus and the increase in the behaviour.
Now change the consequence. Access to a preferred activity is removed after a particular behaviour, and that behaviour becomes less frequent. The word "removed" appears again, but the behavioural consequence differs. Classify the account from both dimensions rather than treating removal alone as the answer.
The point is the distinction, not a recommendation for managing anyone's behaviour. These simplified examples stipulate the observed change so that the reader can practise classification without inventing an outcome.
Write a card with a built-in trap
Put the question on the front: "Does a removed stimulus necessarily mean negative reinforcement?" On the back, write the answer and the reason: no, the direction of change in the behaviour also matters. Then add the two original examples above in your own words.
The useful trap is deliberate. It resembles the shortcut that produced your mistake. A card that only asks for a definition may never force you to confront that shortcut.
Next write a changed example in which the behaviour does not change. Can you confidently assign the learning effect from the consequence alone? The uncertainty should stop you making an unsupported claim about what the intervention achieved. Your revision should distinguish a described intention from an observed effect.
A reusable contrast-card format
Use a small table rather than a page of copied notes. The distinction should remain visible at a glance.
| Card field | What belongs there |
|---|---|
| Confused pair | The two concepts you actually mix up |
| Shared feature | Why they can look similar |
| Decisive distinction | The feature that separates them |
| Original example A | An example supporting the first concept |
| Original example B | A changed example supporting the second |
| Insufficient-information version | A case that does not justify choosing yet |
| Next test | An unseen question or peer-generated variation |
This structure also works for concepts in development, neuroscience and classification, but each pair needs its own authoritative reference. Do not assume that one psychology example validates a whole collection of diagnostic distinctions.
When a classification term has changed, date the source. A card can be beautifully designed and still teach outdated terminology. Revision quality depends on what you put into the card, not the app displaying it.
Use teaching and questions at different points
Return to teaching material when you cannot explain either side of the contrast. Use questions when you can explain both but fail to identify which one fits the vignette. Ask for discussion when the source seems ambiguous or the proposed example does not contain enough information.
The Royal College's examination preparation information is the appropriate reference for the current examination context. Commercial preparation should be matched to the relevant paper rather than chosen merely because it is marketed under MRCPsych.
For a resource decision, inspect a legitimate sample or the material already available in your account. Does its explanation make the boundary clearer? Does it explain why the tempting alternative is wrong? Those questions are more informative than a comparison of total question counts across different products.
Where the Tutor can add something
Per iatroX's September 2026 product specification, the Socratic Tutor begins with an attempted question and asks targeted follow-ups to identify a misconception. Describe the contrast you are struggling with in your own words; do not upload MRCPsych Mentor or SPMM's paid explanations.
A productive follow-up might ask which single change would make your rejected concept fit. Another might present an incomplete example and ask what information is missing. These are suggested learning tasks, not a report of a formal head-to-head platform test.
Question banks, Tutor, study planner, simulations and CPD are included in iatroX's September 2026 subscription: £99 upfront annually, equivalent to £8.25 a month billed annually, or £29 monthly. The relevant value is guided practice around one psychiatry goal, not access to unrelated examinations.
Keep a course when its teaching resolves the confusion. Keep a bank when its explanations help you discriminate. Add guided questioning when definitions are familiar but the distinction repeatedly fails in new examples. There is no need to replace every part of a working revision plan at once.
Frequently asked questions
Is a contrast card better than a definition card?
It serves a different purpose: distinguishing concepts that you confuse. Definition cards can still support basic recall, while contrast cards test the boundary between alternatives.
Can the same method cover all of Paper A?
Use it for recurring confusions, not as a replacement for the whole syllabus. Each topic still needs an appropriate, current source.
Should I buy both MRCPsych Mentor and SPMM?
First identify which learning need a second purchase would address. Another subscription is less useful when the unresolved problem is a distinction you have not yet examined carefully.
