Section B: Option 3 Environmental psychology explained
Environmental stressors like noise trigger biological responses via two pathways: the SAM axis releasing adrenaline for sympathetic arousal, and the HPA axis releasing cortisol.
Read the full explanation
Chronic exposure causes sustained physiological arousal. Black and Black (2007) surveyed residents near Sydney airport and a matched quiet area, measuring chronic noise stress and doctor-diagnosed hypertension. The exposed group reported significantly higher noise stress, but there was no significant difference in hypertension rates between the groups. To manage environmental stress, strategies such as acoustic insulation or increasing perceived control (e.g., allowing individuals to predict or stop the noise) can effectively mitigate these biological stress responses.
Biological rhythms (Biological) – Biological rhythms and the impact of their disruption on our behaviour. Czeisler et al. (1982) Rotating shift work schedules that disrupt sleep are improved by applying circadian principles. At least one strategy for reducing effects of jetlag or shift work.
The daily rhythm is driven by an internal clock in the suprachiasmatic nucleus, entrained by light and by social cues, and it resists being pushed forward faster than roughly an hour a day. Czeisler and colleagues studied workers at a Utah chemical plant on a weekly backward rotating pattern and found far more complaints of disturbed sleep and poor health than among non-rotating workers at the same site. The team then changed the schedule, rotating shifts forward instead of backward and lengthening each rotation, after which workers reported better sleep and greater satisfaction, preferred the longer cycle, and the plant saw improved output and lower staff turnover. What the specification wants explained is the application of clock principles, not shift work in the abstract.
Recycling and other conservation behaviours (Cognitive) – Conservation behaviours and the factors which influence the tendency to conserve or recycle. Lord (1994) Motivating recycling behaviour: A quasi-experimental investigation of message and source strategies. At least one technique used to increase recycling or other conservation behaviour.
Conservation behaviour means action that reduces environmental harm, and this topic asks why favourable attitudes do not always become action. Teach the main levers separately: convenience, prompts at the decision point, commitment, feedback, incentives and social influence. Lord (1994) used a quasi-experiment with 140 households to compare positive and negative recycling appeals delivered through advertising, publicity or personal contact. Researchers directly observed the households’ kerbside recycling before and after the messages, then used a questionnaire to measure beliefs and attitudes. Negative framing delivered by a personal acquaintance produced the greatest increase in observed recycling, while positive appeals produced more favourable beliefs and attitudes.
Ergonomics – human factors (Cognitive) – Cognitive overload and the impact of observation in the workplace environment. Drews and Doig (2014) Evaluation of a configural vital sign display for intensive care unit nurses. At least one workplace design based on ergonomic research.
Human factors work starts from a limited operator rather than a careless one: attention is selective, working memory holds very little, and a display that forces someone to read numbers and hold them in mind while comparing them to remembered norms will eventually cost a mistake. Good design shifts that load onto perception, so a deviation appears as a shape rather than as a value to be interpreted. Drews and Doig (2014) tested exactly that claim with intensive care nurses. Alongside the design question sits the observation question, because performance changes when workers know they are watched, which makes observation both a tool for improving safety and a threat to the validity of any study that uses it.
Psychological effects of built environment (Social) – The impact of the built environment and urban renewal on our wellbeing. Ulrich (1984) View through a window may influence recovery from surgery. At least one example of environmental design used to improve health/wellbeing.
The claim under test is that buildings are not neutral containers: layout, light, height, noise and what a window looks onto all feed into stress, mood and recovery. Two ideas do most of the work. Stress recovery theory says a natural scene lowers physiological arousal within minutes. Defensible space theory suggests that estates giving residents sight lines and ownership of the ground outside their doors are policed by the residents themselves, which is theorised to explain why some post-war high-rise urban renewal schemes produced fear rather than improvement. The prescribed hospital records study turned this from an argument about taste into one about days in a bed and doses of a drug, and it helped introduce evidence-based design into hospital briefs.
Territory and personal space (Social) – Territory and personal space in the workplace. Wells (2000) Office clutter or meaningful personal displays: The role of office personalization in employee and organisational well-being. At least one office design strategy based on research into territory or personal space.
Two related ideas run through this topic. Territory is a place a person claims and marks, and the useful distinction is between primary space that is owned and controlled, secondary space that is shared but familiar, and public space that nobody holds. Personal space is the portable bubble described in work on proxemics, shrinking for intimates and expanding for strangers, and it is invaded rather than entered. Workplaces stress both at once, since an open plan floor removes the walls that marked a primary territory and hot desking removes the desk itself. The prescribed survey of office personalisation asks what employees gain by marking their space, and finds the answer runs through satisfaction with the physical environment to job satisfaction and wellbeing, with managers underrating the benefit.

Section B: Option 3 Environmental psychology exam tips
Marking Points
- Credit for accurately describing the biological pathways as parallel systems: the SAM axis (sympathetic arousal and adrenaline) and the HPA axis (cortisol), leading to sustained physiological arousal.
- Credit for outlining Black and Black's (2007) methodology as a quasi-experiment with a matched comparison area, since exposure was determined by residential location rather than researcher manipulation.
- Credit for accurately reporting Black and Black's findings: distinguishing between the significantly higher noise stress in the exposed group and the lack of significant difference in hypertension rates.
- Credit for suggesting a valid strategy for managing environmental stress, such as acoustic insulation (double glazing) or psychological strategies like increasing perceived control over the stressor.
- Evaluation credit for identifying confounding variables in environmental research, such as air pollution or socioeconomic differences between areas, and the reliance on self-reported health data.
- Credit for distinguishing the internal pacemaker from external time cues, illustrated by free-running evidence such as Siffre's months underground without clocks.
- Credit for explaining direction of rotation, since a phase delay moving morning to afternoon to night follows the natural drift of the clock while a backward rotation forces a phase advance the body resists.
- Credit for the field experiment design with its comparison group of non-rotating workers, and for outcome measures that include productivity and turnover as well as reported sleep.
- Credit for consequences of disruption that go beyond tiredness, such as raised cardiovascular risk among long-serving shift workers and accident risk in the small hours.
- Credit for a strategy applied properly, such as timed bright light and melatonin, forward rotation on a longer cycle, or adjusting sleep before eastward travel, with a reason why flying east is harder than flying west.
- Evaluation credit for ecological validity and genuine workplace outcomes set against an all-male single-site sample, reliance on self-report, and the possibility that workers responded to being consulted rather than to the schedule.
- Describe the quasi-experimental design accurately: 140 households received appeals that varied in framing, positive or negative, and source, advertising, publicity or personal contact.
- Distinguish the measures: researchers directly observed kerbside recycling before and after the messages, then collected questionnaire data about beliefs and attitudes.
- State the pattern of findings carefully: positive appeals produced more favourable beliefs and attitudes, whereas the greatest increase in observed recycling followed a negatively framed message from a personal acquaintance.
- Apply a technique through its mechanism, for example a known community volunteer delivering a concrete reminder can combine personal-source influence with a message at the point of action.
- Credit for the design of the key research: intensive care nurses saw clinical scenarios using an independent measures design, where they used either their usual numerical monitor display or a configural display that draws the vital signs together as one graphic whose shape distorts when a value leaves the normal range.
- Credit for the outcome measures and the result, that nurses identified the patient state more accurately and more quickly from the configural display and rated it as preferable, which supports the claim that pattern recognition costs less than arithmetic.
- Explaining cognitive overload with a mechanism, the limited capacity of attention and working memory and the cost of switching between sources, rather than describing it as having too much to do.
- Using the observation strand precisely: the Hawthorne research is cited for the claim that being studied alters output, and a strong answer notes that the original records have been reanalysed and the effect is far less clean than the textbook version.
- Naming a real workplace design that came from this research, such as shape coded aircraft controls after wartime cockpit errors, or the redesign of nuclear control room panels after Three Mile Island.
- Credit for the matched pairs method: patients recovering from gall bladder surgery in the same hospital were paired on age, sex, weight, smoking and other variables and differed in whether their window faced a small stand of trees or a brown brick wall.
- Credit for reporting all three outcomes rather than one: a shorter postoperative stay for the tree view group by roughly a day, fewer moderate and strong painkiller doses, and fewer negative comments in the nursing notes.
- Evaluation that names a confound, for instance that nurses writing the notes could see the view, which makes that measure vulnerable in a way the discharge date is not.
- Naming a design used to improve wellbeing and saying what it targets, such as a hospital courtyard garden or biophilic planting aimed at stress reduction, single rooms aimed at sleep and infection, or defensible space features aimed at fear of crime.
- A debate point aimed at content: environmental determinism overstates the case if the design is treated as the cause of recovery, since the same view does nothing for a patient who never looks out of it.
- Describing the key research accurately as a large questionnaire survey of employees across many small and medium businesses in one American county, with a parallel set of responses from managers about the organisation's policy on personalising a workspace.
- Reporting the pattern rather than a single line: women personalised more than men and used more relational items such as photographs and plants while men used more items marking achievement, and the amount of personalisation was associated with satisfaction with the physical environment, which in turn was associated with job satisfaction and wellbeing.
- Naming the organisational finding, that firms with permissive policies had employees reporting greater wellbeing while managers tended to see personal items as clutter, since that is the point an application question is built from.
- Being explicit that the data are correlational, so a plausible reverse reading is that satisfied employees are the ones who settle in and decorate.
- An office strategy that follows from the theory, such as guaranteed personal storage and a nameplate where hot desking is unavoidable, screens and spacing to protect conversational distance, or zoning quiet and collaborative areas.
Examiner Tips
- 💡Application questions in this option often provide a specific scenario (e.g., a noisy workplace); ensure you match the environmental stressor in the stem to the biological response before suggesting a management strategy.
- 💡When asked to explain biological responses, clearly distinguish between the SAM axis (immediate adrenaline release) and the HPA axis (longer-term cortisol release) to secure full marks for mechanisms.
- 💡Questions ask you to suggest a schedule for a named workforce, so be ready to write a rota with the direction and the rotation length justified.
- 💡Where the command word is evaluate, the sample is the obvious weakness; push further and question whether reported satisfaction is the right outcome measure.
- 💡Learn one disruption of jet lag and one of shift work so that either version of the strategy question can be answered.
- 💡For an application item, name the messenger and message, describe where and when it reaches the target group, and state an observable measure of behaviour.
- 💡In evaluation, use the combination of direct observation and questionnaire data: behavioural observation reduces reliance on self-report, while the questionnaire helps separate attitudes from action.
- 💡Scenario questions hand you a control room, cockpit or ward and ask you to suggest a design change. Anchor the suggestion in a named limit of attention or memory, then say what the operator would see instead.
- 💡When asked to evaluate the key research, use the independent measures design on both sides: it prevents order and practice effects, but introduces potential participant variables between the two groups of nurses.
- 💡If the question asks you to explain how observation affects behaviour in the workplace, answer for both directions, the improvement while watched and the distortion it creates in the data.
- 💡Questions often ask you to suggest how a named building could be improved. Pick two features, say which psychological outcome each targets, and say how you would measure the outcome.
- 💡For evaluation, note that the study only used records from May to October when the trees were in foliage; this seasonal restriction limits generalisability to winter months.
- 💡If asked to discuss usefulness, point to how far this single study moved hospital design, then note the cost argument that a view is easier to recommend than to retrofit.
- 💡Application questions usually describe a firm moving to open plan or hot desking. Answer with a specific change, the territorial or proxemic reason for it, and one predicted effect on staff.
- 💡Evaluate the self report method properly: social desirability and the tendency to rate everything positively when satisfied are more precise criticisms than saying questionnaires are unreliable.
- 💡Where a question invites a debate, ethnocentrism is the natural one here, since norms for distance and for marking space differ markedly between cultures.
Common Mistakes
- Stating that Black and Black (2007) found higher rates of hypertension in the noise-exposed group. Correction: The study found no significant difference in hypertension between the exposed and control groups, only higher noise stress.
- Conflating the SAM and HPA axes into a single chain. Correction: They are distinct parallel systems; adrenaline does not cause the release of cortisol.
- Failing to link the management strategy back to the biological response. Correction: When suggesting a strategy like acoustic insulation, explicitly state how it reduces the activation of the SAM and HPA axes by removing the environmental trigger.
- Writing that the workers were tested in a laboratory. This ran in a working plant, which is the source of both its strength and its confounds.
- Saying jet lag comes from the length of the flight. It comes from crossing time zones and from the direction of travel, and a long journey north to south produces very little of it.
- Treating melatonin as a cure without saying when it is taken, since timing decides whether it advances or delays the rhythm.
- Claiming that Lord measured behaviour only by questionnaire. Correction: recycling was directly observed before and after the appeal; the questionnaire measured beliefs and attitudes as additional outcomes.
- Claiming that Lord only observed bins and collected no self-report data. Correction: the study combined direct behavioural observation with questionnaire measures.
- Calling the study a laboratory experiment or claiming complete random allocation, when it was a community quasi-experiment with households in their ordinary setting.
- Saying that one framing was best for every outcome. Correction: positive appeals favoured beliefs and attitudes, while a negative personal message produced the greatest behavioural increase.
- Reducing ergonomics to chairs, desk height and posture, which is the physical half of the field and not the cognitive half the statement asks for.
- Saying the new display is better without saying better at what, when the study measured accuracy and response time on scenarios and not survival or error rates on real wards.
- Treating a simulated scenario as identical to a live shift, so the alarms, interruptions and fatigue that cause overload in practice are never mentioned.
- Describing the Hawthorne effect as a permanent productivity gain, when the interest is in a temporary change caused by attention from researchers.
- Calling the study a true experiment. Nobody allocated patients to a view, so it is a natural or quasi-experiment and causal language has to be hedged.
- Remembering only the length of stay and losing the analgesic and nursing note findings, which are the results that make the stress explanation plausible.
- Writing that nature is good for people as the whole answer, with no mechanism such as reduced physiological arousal or restored attention.
- Treating urban renewal as automatically harmful, when the research question is which features of a scheme, not whether new buildings are bad.
- Mixing up territory and personal space, then writing that someone standing too close has invaded a primary territory.
- Quoting the gender difference as a fixed fact about men and women rather than as a pattern in one workplace culture at one time, which is where the gender bias point belongs.
- Claiming the study shows personalisation causes wellbeing, when the design cannot support the arrow in either direction.
- Recommending an office change with no psychology attached, so the answer reads as interior decoration rather than as applied social psychology.
