AL Psych Juris common mistakes

AL Psych Juris · Understand the traps and how to avoid them.

Mistake 1

On questions describing a client's presenting problem, selecting an intervention or diagnosis before checking whether the stem asks for the single best next step versus the best overall treatment, then defending the answer chosen first.

Stems on this exam often hinge on sequencing (e.g., assess before treating, rule out medical causes before assigning a psychological diagnosis), and candidates under time pressure lock onto the most familiar clinical content word in the stem.

What to do instead

Before answering, underline the task verb (assess, refer, diagnose, intervene, document) and the time frame (first, next, most likely, ultimately). Eliminate any option that performs a later step before a necessary earlier one.

Mistake 2

Treating the DSM criteria as sufficient for diagnosis and ignoring that the stem explicitly excludes a substance, medical condition, or another disorder, then picking the diagnosis that matches the symptom list.

Candidates memorize symptom clusters but drop the exclusion and duration criteria, which are exactly where exam writers place the discriminating detail.

What to do instead

For every diagnostic question, recite the exclusion criteria and duration requirement aloud in your head before comparing options; strike any option whose criteria are violated by a fact in the stem.

Mistake 3

Choosing a statistically significant result as evidence of clinical importance, or choosing 'no effect' because the sample was small, without reading the effect size and confidence interval information given.

Candidates conflate p-values with magnitude and are trained in coursework to treat significance as the end of the analysis, while the exam tests interpretation of effect sizes and CIs.

What to do instead

When a stem supplies effect size, CI, or N, answer from those numbers: wide CIs and small effects mean the finding is uncertain or trivial regardless of p. Practice stating what a CI means in one sentence.

Mistake 4

Applying a single theoretical orientation (often the candidate's own) to every treatment question instead of matching the empirically supported treatment to the disorder named.

Clinicians default to the model they were trained in, and the exam deliberately offers plausible options from several orientations for the same case.

What to do instead

Build a disorder-to-first-line-treatment table (e.g., exposure-based CBT for OCD and panic, behavioral activation or CBT for depression, DBT for borderline features) and answer from that table, not from personal preference.

Mistake 5

Ignoring base rates and prior probability when interpreting a test result, and answering as if a positive result on a screening measure confirms the diagnosis.

Candidates reason from sensitivity and specificity alone because those are the numbers they can recall, forgetting that low prevalence produces many false positives.

What to do instead

For any screening or classification stem, ask 'what is the prevalence here?' and reason through the positive predictive value qualitatively before selecting an option.

Mistake 6

Missing ethical decision points embedded in otherwise clinical stems, such as a client requesting records, a subpoena, a dual relationship, or a minor's confidentiality, and answering the clinical question instead.

The stem reads like a therapy case, so attention goes to the disorder rather than to the legal or ethical trigger phrase buried in the last sentence.

What to do instead

Scan each stem specifically for trigger words (subpoena, records, minor, gift, barter, colleague impairment, mandated reporting) and, if present, answer the ethics or legal question first.

Mistake 7

Selecting a biological or neuropsychological answer based on a single keyword (e.g., 'memory' leading to hippocampus) without checking whether the described function matches the structure or pathway named in the options.

Keyword-to-structure associations are overlearned and survive even when the stem describes a different function or a disconnection syndrome.

What to do instead

For neuro questions, restate the deficit in functional terms (encoding versus retrieval, recognition versus recall, declarative versus procedural) and map function to system before looking at options.

Mistake 8

Treating developmental milestones and normal variation as pathology, or applying adult criteria to a child, in stems describing a child whose behavior is within normal limits for the stated age.

Candidates over-pathologize because the exam's clinical framing primes a disorder answer, and they underweight the age given in the stem.

What to do instead

For every child or adolescent stem, first state what is typical at that age, then decide whether the behavior exceeds normal variation; choose the developmental or normative option when it fits.

Mistake 9

Answering social psychology questions from intuition about how people behave rather than from the named phenomenon, confusing related effects (e.g., fundamental attribution error with actor-observer bias, conformity with obedience).

Everyday intuitions feel authoritative, and closely related social phenomena share surface descriptions, so candidates pick the more familiar label.

What to do instead

Write one-line discriminating definitions for each pair of confusable effects and match the stem's direction of judgment or source of influence to the precise definition before choosing.

Mistake 10

Misreading the research design in a methods stem, such as treating a quasi-experimental or correlational study as if it supports causal conclusions, or misidentifying the threat to validity named in the options.

Candidates focus on the topic of the study rather than its design, and validity threats (maturation, regression to the mean, selection, instrumentation) are easily confused under time pressure.

What to do instead

For each methods stem, first label the design (true experiment, quasi-experiment, correlational, single-case) and the specific threat described, then eliminate options that claim more causal warrant than the design allows.
