Which statement best distinguishes the study of table spacing from Hall’s personal-space zones?
What you will learn
- Explain Hall’s intimate, personal, social and public zones and their limits across cultures
- Apply overload, arousal and behaviour constraint to restaurant-table spacing; Robson et al. (2011)
- Describe queue intrusion, number of intruders, social structure and responses; Milgram et al. (1986)
- Evaluate individual and situational explanations, cultural differences, observation, quantitative and qualitative data, and ethics
Hall’s four zones describe culturally learned interpersonal distances
Hall’s proxemic model describes four broad zones: intimate distance for close contact (approximately 0–18 inches); personal distance for familiar conversation (about 18 inches–4 feet); social distance for more formal interaction (about 4–12 feet); and public distance for addressing a larger or less familiar audience (beyond about 12 feet). These approximate ranges came from Hall’s observations of US settings; they are not universal measurements or rules for every person.
At restaurant tables, the distance between neighbouring tables can affect whether diners feel private, exposed or able to move comfortably. A table-to-table gap is not the same thing as the distance between two people in Hall’s zones. Seating design should also consider party size, mobility, hearing, cultural expectations and the purpose of the meal.
Crowding can be physical density, such as the number of people or distance between tables, and perceived crowding, such as feeling intruded on or constrained. The same density can be experienced differently by different people and in different situations.
Overload, arousal and behaviour constraint are possible explanations
Environmental overload occurs when the demands or stimulation in a setting exceed what a person can comfortably process. Close seating, noise and being overheard may increase perceived intrusion or stress for some diners. Arousal describes activation; it does not by itself mean pleasure or displeasure.
Behaviour constraint describes a feeling that the environment restricts what someone can do—for example, finding it difficult to get up, speak privately or relax without disturbing another table. A diner may respond by changing behaviour, avoiding the situation or leaving. These are explanatory concepts; a study must measure them rather than assume them.
Robson, Kimes, Becker and Evans (2011) surveyed more than 1,000 Americans about projected restaurant scenes. Respondents considered parallel tables separated by 6, 12 or 24 inches in different dining contexts. They generally objected to close spacing, especially in a romantic context; women reported less comfort than men in tight quarters. The paper also reports that the spacing conditions did not significantly change its arousal measures.
The survey recorded feelings and intended behaviour about pictured or projected arrangements, not real-time reactions in a restaurant. It therefore informs perceived comfort and intentions, but cannot by itself prove that a particular gap causes physiological arousal, early departure or reduced sales in all venues. Context and actual restaurant use matter.
Milgram et al. (1986) studied how people defend a queue
A queue is a social arrangement that coordinates who receives a service first. Its order is visible, and people generally share a first-come, first-served rule. An intrusion challenges both physical spacing and this shared expectation.
Milgram and colleagues sent confederates into 129 naturally occurring waiting lines and observed people’s responses. People standing behind the point of intrusion were more likely to object than people who were ahead of it; two intruders drew more reactions than one; and passive confederates acting as buffers reduced the response. Reactions were local around the intrusion rather than a coordinated response from the whole line.
This field observation shows that responses depend on queue structure and nearby people, not only on an individual’s stable preference for personal space. It does not mean every queue or culture will respond in the same way. The study’s public setting adds everyday realism, while the number and type of intrusions, location and social context limit generalisation.
The study also raises ethical questions: the people queuing did not give advance informed consent to an intrusion that could cause annoyance or conflict. A modern replication would need to minimise distress, consider debriefing and privacy, avoid recording identifiable bystanders without consent, and justify why a less intrusive method would not answer the question.
Combine methods and explanations without overclaiming
Questionnaire ratings provide quantitative or qualitative self-report; observation records what people do; an interview can add detail about why a setting felt intrusive. A photo-based scenario offers control over spacing but may not reproduce a real meal. A field observation captures a natural setting but has less control over party, occasion, service and customer differences.
A strong explanation identifies the setting and the person’s goal, then connects an observed cue to a measured response. Individual factors can include privacy needs, familiarity and mobility; situational factors can include spacing, queue length, companions and time pressure. Cultural differences should be explored rather than inferred from nationality alone.
In Robson et al., the image-based survey was not a direct measure of the full response process. In Milgram et al., observation captured spontaneous objections but created a consent and distress concern. Method, evidence and ethics should be evaluated together.

Pause and explain
Which result is supported by Milgram et al. (1986)?
Worked example
A restaurant manager claims, ‘Robson et al. proved that tight table spacing raises arousal, so every customer will leave sooner.’ Evaluate the claim.
Show the worked solution
- State what the study manipulated and measured.
- Report the result for spacing and arousal without adding an unmeasured outcome.
- Explain one limit and one contextual factor.
Answer Robson et al. surveyed more than 1,000 Americans about projected restaurant scenes with different table gaps and dining contexts. Respondents objected to close spacing, especially in a romantic context, but the study did not find a significant effect on its arousal measures. It measured intentions and emotional ratings, not every diner’s actual departure, and the response may depend on the meal context and customer.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Two diners say that tables 6 inches apart feel uncomfortable, while others say the same room feels lively. Use Hall and one personal-space explanation without treating either response as universal.
Give me a hint
Separate physical spacing, perceived space and the two diners’ interpretations.
Compare my reasoning
- A six-inch table gap is a feature of the seating layout; it is not itself one of Hall’s interpersonal zones.
- Close tables may feel intrusive or constrain movement for some diners, while others may tolerate or enjoy a lively setting.
- Purpose, companions, privacy needs, culture, mobility and expectations can change the experience; measure these rather than assume them.
The table gap describes physical layout, while Hall’s zones describe interpersonal distance. Overload or behaviour constraint may explain discomfort, but the same setting can feel lively to another diner. The response depends on personal needs and context.
Look for these in your work
- Table gap and Hall zones distinguished
- A relevant explanation applied
- Individual and situational factors considered
Evaluate the claim: ‘Milgram et al. proved that people naturally protect their personal space by confronting queue jumpers.’
Give me a hint
Use the method, the local response pattern and an alternative explanation.
Compare my reasoning
- Confederates entered 129 naturally occurring lines, and researchers observed objections and other reactions.
- Those behind the intrusion were more likely to object; two intruders caused more response than one, and buffers dampened it.
- The findings fit a situational account based on the queue’s first-come rule and local social structure; the observation also raises consent and distress concerns.
The claim is too broad. Milgram et al. observed responses to queue intrusions, and reactions depended on position, number of intruders and buffers. This suggests a shared first-come rule and local queue structure, not a universal individual tendency to confront. The public intrusion also raises ethical concerns about consent and distress.
Look for these in your work
- Method and evidence stated
- Situational account explained
- Ethical limitation included
A restaurant wants to compare two table layouts and a manager also wants to know whether diners feel their privacy is protected. Plan an ethical study that measures both experience and behaviour.
Give me a hint
Use separate outcomes for rating privacy and observed actions, and avoid assuming one causes the other.
Compare my reasoning
- Compare the layouts during similar service periods or use a controlled mock-up; keep party size, menu, price and service as similar as practical.
- Ask diners voluntarily about comfort and privacy, and separately record a low-identification behaviour such as whether the party requests a seat change or leaves early.
- Explain the study, protect responses and any recordings, obtain consent for identifiable observation, and account for occasion and party relationship before interpreting differences.
A fair comparison holds the meal and service conditions as similar as practical, measures privacy ratings separately from actions such as seat-change requests, and avoids linking them causally without evidence. Use voluntary participation, minimise identifiable records and account for dining context.
Look for these in your work
- Layout comparison defined
- Self-report and behaviour separated
- Consent, privacy and context addressed
Common mistakes
- Treating Hall’s distance ranges as universal across cultures and individuals
- Confusing a gap between tables with interpersonal distance between two people
- Saying Robson et al. found that closer tables significantly increased arousal
- Claiming a survey of projected scenes observed real restaurant behaviour
- Explaining queue objections only through personality and ignoring the first-come social rule
- Ignoring consent, privacy and distress when evaluating queue-intrusion observations
What can you explain now?
What is one finding from Milgram et al. (1986) that supports a situational explanation of queue behaviour?
Compare with the explanation
Objections depended on where people stood relative to the intrusion, the number of intruders and the presence of buffers.
The observed response varied with the queue arrangement, so it cannot be explained only by a stable individual trait.
