Context errors = rating employees by comparison instead of objective performance
Cross-sectional design = different cohorts of ppl
Cross-sequential design = combination of longitudinal + cross sectional (re-test cross sectional sample)
Developmental coordination disorder = fine motor function disorder (clumsiness → not always neuro cause)

Stereotype threat = confirming neg stereotype of a group → poor performance
Systemic therapy = awareness of relationship with others
Youth diagnostics = child + parent are the client
Problems:
● Either diagnosis or not
● Not all disorders in childhood fit into homogenous categories
● Valuable info gets lost
● Diagnostic criteria not well defined → leaves room for interpretation
● Lack of clear procedures
Volition = intentional behaviour, conceptualising goals
Characteristics of tests
● Standardised procedure → same for everyone (instructions, administration)
● Limited samples of examinee’s behaviour → only cover part of patient’s behaviour (items must be chosen so
inferences can be made about the entire domain)
● Prediction of non-test behaviour → prediction of depression w/ sleep questions
● Classification/quantification → inferences + categorization made
● Interpretation based on norms → does patient score averagely? Extent to which it deviates?
Uses of tests
● Classification
○ Placement → sorting ppl into categories based on their needs/skills
○ Screening → quick tests identifying ppl with special needs
○ Certification → indicates someone has min. skill required (driving)
○ Selection → (attending uni, job)
● Diagnosis → etiology + choices for treatment
● Self-knowledge → insightful (change careers)
● Program evaluation → what can be done to improve program??
● Research → applied or theoretical
Influences of tests
● Non-standard procedures → render invalid results (clinical judgements can have larger deviations)
● Test administration
○ Individual → sensitivity to disabilities (mild: adjustments) + (severe: special tests, adjusted norms)
○ Group → incorrect timing, clarity, noise, failure to explain no guessing
● Examiner → establishing comfortable environment, sex, experience, race
● Examinee → text anxiety, malingering
Responsibilities of test publishers
● Public marketing issues → should include manuals, guides
● Competence of test purchasers → restricted access
○ Level A → non-psychologists
