What a finished PSY-831 Topic 3 arousal model critique looks like
The finished critique starts with the source. Robert Yerkes and John Dodson studied mice learning a discrimination under shocks of varying strength, and the familiar curve relating arousal to athletic output was built by later readers from a narrower result. The critique then tests three successors on one composite case, a pistol shooter whose scores hold through qualification and then fall sharply in a final. Yuri Hanin's individual zones model is credited for placing the optimum differently for different people. Lew Hardy's catastrophe model is credited with explaining sudden collapse when physiological activation climbs while cognitive anxiety is already high. Graham Jones's directional work adds that performers read the same symptoms as helpful or harmful. The critique chooses the catastrophe account for this case and states the evidence that would overturn the choice.
How a PSY-831 Topic 3 example is structured
The critique is organized as a trial of four models against one set of facts. Its opening section states the facts of the composite shooter, including the abruptness of the drop, since a model must explain its shape as well as its occurrence. A second section returns the inverted-U to its origin and lists what the curve predicts, a gradual rise and a gradual fall. Sections on individual zones, catastrophe and direction follow, each stating the model's claim, its main evidence and its prediction for the shooter. A comparison table then sets the four predictions side by side against the observed pattern. The discussion argues for the catastrophe account while conceding that its three-dimensional form is hard to test outside the laboratory. A last paragraph names the finding that would reverse the verdict.
The shape of the drop matters
The composite shooter's scores fall abruptly in finals, and the critique insists that any adequate model explain the sudden shape as well as the decline.
The curve returned to its source
Yerkes and Dodson's study of mice and shock strength is summarized accurately, showing how much later readers added when they turned it into a law.
Optimal zones that differ by person
Hanin's model is credited for locating the best level of activation differently for each performer, though it predicts a gradual rather than sudden decline.
Catastrophe and the role of worry
Hardy's model explains a sharp collapse when physiological activation rises while cognitive anxiety is already high, which fits the shooter's pattern most closely.
Symptoms read as help or harm
Jones's directional research shows performers interpreting identical symptoms as facilitative or debilitative, so intensity alone cannot carry the whole explanation.
A verdict with its refutation
The critique selects the catastrophe account for this case and names the observation, a gradual decline under high worry, that would overturn the selection.
Where marks go in PSY-831 Topic 3
The inverted-U presented as settled science costs this critique most, since its origin lies in animal learning and its athletic form was an extrapolation. A related loss is describing the curve as simply wrong, when it captures something real about too little and too much activation and a critique should say what. Models summarized without predictions cannot be compared, which leaves the verdict looking like preference. Papers treating arousal and anxiety as interchangeable lose the distinction on which the catastrophe account depends. Another common gap is ignoring interpretation, so that two performers with the same heart rate are assumed to share one experience. A critique that recommends relaxation for everyone has abandoned the individual zones evidence it has only just reviewed.

PSY-831 Topic 3 questions, answered
Did Yerkes and Dodson study arousal in athletes?
No. They studied how quickly mice learned a visual discrimination when mild electric shocks of different strengths followed errors, and reported that the most effective strength depended on how hard the discrimination was. The broad claim that moderate arousal produces the best human performance was built from that result by later authors, which is why a doctoral critique returns to the original.
What is the catastrophe model?
Lew Hardy's proposal, developed with John Fazey, that the effect of physiological arousal depends on cognitive anxiety. When worry is low, rising arousal affects performance gradually, much as the inverted-U suggests. When worry is high, performance can fall suddenly past a threshold, and recovery then requires a larger drop in arousal than the rise that caused the collapse.
Is high arousal always harmful?
No, and much of the research that followed the curve exists to say so. Some performers do their best work at levels others would find overwhelming, and many read a racing heart as readiness rather than threat. The critique treats the question as individual and interpretive, and it avoids recommending any single level, since the models it reviews disagree precisely on where that level sits.
