effort

Working conception

A place to establish whether effort denotes experience, expenditure, mobilisation or another explicitly supported construct.

1. How does the selected conception define effort, and is its use of energy literal, metaphorical or operational? definition
2. Which read sources and research traditions support this conception, and which competing definitions do they distinguish? provenance

Exertion versus adjacent constructs

Separate an effort episode from intention, exposure to demands, mere duration and resulting achievement.

1. What identifies the actor, activity and beginning and end of the proposed exertion episode? boundary
2. What evidence supports exertion rather than only motivation, task difficulty, time spent or output? boundary

Effort rating context

Specify rating anchors, timing and the sensations the actor was asked to judge.

1. Which scale and anchors were used, and was the rating collected during exertion or retrospectively? measurement
2. How did the instructions distinguish felt effort from pain, discomfort, fatigue and frustration? boundary

Indicator validity

Document the evidence and assumptions connecting an indicator to the selected effort conception.

1. What evidence validates the selected indicator for this activity, population and definition of effort? provenance
2. Which alternative explanations, such as arousal, movement, strategy or skill, could produce the observed indicator value? measurement
3. How should disagreement between an indicator and the actor's report affect the assessment? action

Demand and capacity reference

Make the actor-specific basis of relative effort judgements explicit.

1. Which physical or mental demands are present, and which are actually engaged by the actor's strategy? definition
2. What current capacity assessment or baseline supports interpreting those demands as relatively high or low? measurement

Comparison conditions

State when effort comparisons across attempts or actors are interpretable.

1. Were task conditions, output quality, skill, assistance and measurement methods sufficiently comparable? measurement
2. Could a change in observed effort reflect a different strategy or level of assistance rather than a change in commitment? boundary
3. Which adjustment could reduce unnecessary exertion while preserving the actor's intended result? action

Intensity and duration pattern

Capture how exertion changes without treating elapsed time as accumulated effort.

1. When did active exertion, pauses and substantial intensity changes occur? measurement
2. Does the chosen measure justify aggregation across time, and what information would an aggregate conceal? measurement

Effort adjustment basis

Connect changes in exertion to stated goals, feedback, competing activities and actor limits.

1. What evidence explains an increase, reduction or withdrawal of effort without assuming laziness or lack of motivation? provenance
2. Given the actor's goals, feedback and reported limits, should the next step be persistence, a strategy change, assistance, a pause or stopping? action

Basis of hard-work claims

Trace claims of high or low effort to their claimant, criteria and evidence.

1. Who describes this activity as hard work, and what criteria do they apply? provenance
2. Which aspects of exertion are unavailable to the observer, and how does that limit the attribution? boundary

Warranted effort decisions

Separate descriptive assessment from judgements about credit, obligation and support.

1. What additional criteria are required before an effort estimate can justify praise, reward, workload changes or corrective feedback? action
2. How can the actor correct or contest an effort attribution, especially when low visible output prompted it? action

Check these first

Recalled without web access and unsourced; every item is a lead to verify.

• This covers exertion and hard work, not 'an effort' meaning an organized undertaking or an individual attempt.
• Psychological accounts differ over whether effort is primarily resource mobilization, control allocation, experienced exertion or willingness to bear costs; no single operationalization settles these differences.
• Measurement details are recalled rather than checked: researchers should verify the relevant scale version and distinguish subjective effort from physiological and performance proxies.

1. Which of these check these first hold for the sense of effort this model covers, and on what evidence? provenance

• Physical effort
• Mental or cognitive effort
• Combined physical and mental effort

Real-world use

• Adjusting exercise intensity using perceived exertion.
• Assessing the demands of jobs, equipment and interfaces in ergonomics.
• Studying how motivation, incentives and fatigue affect task engagement.
• Planning rehabilitation activities relative to a person's capacity.
• Evaluating the effort required for learning and problem solving.

Typical measurements

Recalled without web access and unsourced; every item is a lead to verify.

• Perceived exertion on the Borg Rating of Perceived Exertion scale - 6-20, the scale's bounds rather than a population reference range - Ordinal rating
• Subjectively rated effort on the NASA Task Load Index effort subscale - 0-100, the scale's bounds rather than a population reference range - Rating points

1. Which of these typical measurements hold for the sense of effort this model covers, and on what evidence? provenance

Failure modes and hazards

Recalled without web access and unsourced; every item is a lead to verify.

• Physical exertion exceeding a person's capacity or recovery can contribute to injury, heat illness or excessive fatigue.
• Sustained demanding mental activity can produce fatigue and increase errors.
• Treating performance as a direct measure of effort ignores differences in skill, capacity, strategy and circumstances.
• Treating heart rate, energy expenditure or pupil dilation as specific measures of effort overlooks other influences on those signals.
• Equating effort with moral worth can unfairly penalize people whose limitations or exertion are not visible.

Neighbouring kinds and how to tell them apart

Recalled without web access and unsourced; every item is a lead to verify.

• Energy expenditure - Energy expenditure is a physiological quantity expressible in joules or kilocalories; effort has no universal conversion into energy units.
• Mechanical work - Mechanical work involves force acting through displacement; maintaining a static load can require effort while producing no external mechanical work.
• Task difficulty - Difficulty concerns how challenging a task is relative to capacity; effort concerns exertion during the attempt, and a difficult task can be abandoned with little effort.
• Motivation - Motivation concerns processes that initiate and direct action; effort concerns the exertion invested in carrying it out.
• Fatigue - Fatigue concerns tiredness or reduced capacity; effort is exertion and may occur before fatigue develops.
• Performance - Performance concerns achieved results; substantial effort can yield poor results, and skilled performance can require little effort.
