Karnataka II PUC Psychology (KSEAB) common mistakes
Karnataka II PUC Psychology (KSEAB) · Understand the traps and how to avoid them.
Writing that psychology is the 'science of the soul' or 'study of behaviour only' when asked to define psychology, instead of giving the current definition as the scientific study of mental processes and behaviour.
Candidates memorise the older etymological definition (psyche + logos) from the opening paragraph of the textbook and stop there, missing that the modern definition includes both mental processes and behaviour, and that it is a science.
What to do instead
Prepare a one-line definition you can reproduce: 'Psychology is the scientific study of mental processes and behaviour.' When a 2-mark question asks for a definition, add one sentence naming both components and one sentence on why it counts as a science (systematic observation, testable hypotheses).
Confusing the experimental method with the correlational method: claiming an experiment 'shows a relationship between two variables' without naming manipulation of the independent variable and control, or claiming a correlation proves causation.
Both methods involve measuring variables and both produce numbers, so candidates reuse the same phrasing. The key distinction (manipulation and control versus measurement without manipulation) is a single sentence in the chapter and is easily skipped.
What to do instead
Learn a two-column contrast: experiment = manipulation of IV, control of extraneous variables, random assignment, causal inference; correlation = two variables measured as they occur, coefficient from -1 to +1, no causal claim. Practise rewriting any correlation finding with the phrase 'is associated with, but does not cause'.
Mixing up longitudinal and cross-sectional designs, or describing a case study as if it were a survey, when asked to identify or evaluate a research design.
The names are learned as labels without the defining feature (same participants over time versus different age groups at one time), and case studies are remembered as 'studying people' rather than as intensive study of a single individual or unit.
What to do instead
Attach one concrete example to each design: longitudinal = same children tested at ages 5, 10 and 15; cross-sectional = 5-, 10- and 15-year-olds tested once; case study = detailed study of one child's language development. In evaluation questions, add the standard limitation for each (longitudinal: time, attrition; cross-sectional: cohort effects; case study: poor generalisability).
Treating Piaget's stages as fixed ages only, and failing to name the cognitive achievement and limitation of each stage - for example calling object permanence a concrete-operational achievement or saying egocentrism ends in the preoperational stage.
Candidates memorise the age ranges (0-2, 2-7, 7-11, 11+) and assume the marks come from the ages, so they never learn the paired achievement/limitation for each stage, which is what application questions test.
What to do instead
Build a four-row table with columns: stage, age, key achievement, key limitation. Sensorimotor: object permanence / lack of symbolic thought. Preoperational: symbolic play and language / egocentrism, centration, irreversibility. Concrete operational: conservation, classification, seriation / difficulty with abstract and hypothetical reasoning. Formal operational: hypothetical-deductive reasoning / adolescent egocentrism. Recite the table before the exam.
Answering a signal-detection or attention question by defining only 'absolute threshold' and ignoring the four outcomes of signal detection (hit, miss, false alarm, correct rejection), or confusing selective and divided attention.
Thresholds are the first bolded terms in the chapter and get revised; signal detection theory and the types of attention appear later and are skimmed. Selective and divided attention sound interchangeable to a candidate reading quickly.
What to do instead
Draw the 2x2 signal-detection table (signal present/absent x response yes/no) and label all four cells. For attention, fix one example each: selective = listening to one voice at a party; divided = driving while talking; sustained = watching a radar screen. Use the example first, then the definition, in your answer.
Describing classical conditioning but mislabelling the elements - calling the unconditioned stimulus the conditioned stimulus after pairing, or naming salivation as the conditioned response before conditioning has occurred.
The labels change meaning across the procedure (neutral stimulus becomes CS; the response is unconditioned before pairing and conditioned after), and candidates memorise the list of terms without tracking the timeline.
What to do instead
Write Pavlov's procedure as a timeline with arrows: food (UCS) -> salivation (UCR); bell (neutral) + food -> salivation; bell alone (CS) -> salivation (CR). Then answer any labelling question by locating the event in this timeline before naming it. Add one line each on extinction, spontaneous recovery and stimulus generalisation.
Confusing the three memory stores on the wrong dimension - giving capacity in seconds, or duration in items - and failing to state the capacity of short-term memory as about 7 plus or minus 2 chunks.
Duration and capacity are learned as two numbers without being tied to the store they belong to, so they swap under exam pressure. The chunking idea is also often omitted.
What to do instead
Memorise a three-row table: sensory memory (duration under a second, large capacity); short-term memory (duration about 20-30 seconds without rehearsal, capacity 7 plus or minus 2 chunks); long-term memory (duration relatively permanent, effectively unlimited capacity). State the number with its unit every time you write it.
Treating heuristics and biases as synonyms for 'thinking errors in general', and being unable to give a concrete example of availability, representativeness or anchoring when an application question describes a judgement.
The terms are abstract and the textbook examples are short, so candidates learn the names but not the trigger that identifies each one in a scenario.
What to do instead
Anchor each to a one-line trigger: availability = judging likelihood by how easily examples come to mind (fearing plane crashes after news coverage); representativeness = judging by similarity to a prototype while ignoring base rates; anchoring = over-relying on the first number offered. In application questions, quote the phrase in the scenario that matches the trigger before naming the bias.
Listing motivation and emotion theories without matching each to its core claim, so that Maslow's hierarchy is described as a drive-reduction theory, or James-Lange and Cannon-Bard are given the same sequence of events.
The theories are learned as a list of names for a 'write short notes' question, and the distinguishing claim of each is never separated out, so the names collapse into each other.
What to do instead
Write one contrast sentence per pair. James-Lange: bodily arousal first, emotion follows. Cannon-Bard: arousal and emotion occur simultaneously. Schachter-Singer: arousal plus cognitive label produces emotion. Maslow: needs arranged in a hierarchy from physiological to self-actualisation. Drive-reduction: a biological need creates a drive reduced by satisfying the need. Learn the sequence, not just the name.
Confusing intelligence and personality concepts that share vocabulary - describing IQ as normally distributed with a mean of 100 but then giving the standard deviation as 15 for a test whose SD is different, or mixing trait, type and psychodynamic approaches to personality in one answer.
Intelligence and personality are revised together at the end of the course, and the numbers and approach names blur. Candidates also import the normal-curve facts into personality answers where they do not belong.
What to do instead
Keep a single fact card: IQ mean 100, SD commonly 15, roughly two-thirds of scores between 85 and 115. Keep a separate card listing personality approaches (type, trait, psychodynamic, humanistic, behavioural) with one defining claim and one theorist each. Before writing, check which chapter the question comes from and use only that card.
Answering a social-influence question by defining conformity, compliance and obedience as 'changing behaviour because of others', without distinguishing whether the change is due to group pressure, a direct request, or an authority command, and without naming Asch or Milgram where the question invites it.
All three terms describe social influence, so a single vague definition feels sufficient; the distinguishing feature (source and nature of the pressure) is what actually earns the marks.
What to do instead
Learn a three-line contrast with a study attached: conformity = change in belief or behaviour under real or imagined group pressure (Asch's line-judgement study); compliance = change in behaviour in response to a direct request, belief unchanged; obedience = change in behaviour in response to an authority command (Milgram). In application questions, identify who applied the pressure and how, then choose the term.
