Original StudyForA teaching mapped to the Cambridge 2028–2030 Version 1 syllabus. It is not Cambridge material, an official mark scheme or an awarded grade. Research findings are summarised for learning and should not be treated as universal consumer rules.

Before you begin

  • This lesson covers Cambridge Psychology 9990 Consumer Psychology section 2.2.2 in the 2028–2030 Version 1 syllabus. Eye-tracking, self-report and recorded orders measure different outcomes.

Work on paper. Try each question before revealing help, and explain why your method works.

Quick readiness check

What does eye-tracking directly record during a menu task?

What you will learn

  • Explain positive and negative menu-design features and how eye-tracking can test visual attention; Pavesic (2005)
  • Distinguish sequential primacy and recency from simultaneous menu-position effects; Dayan and Bar-Hillel (2011)
  • Describe Lockyer (2006) on menu wording and item choice
  • Apply everyday menu design and evaluate field experiments, objective and subjective data, generalisation and validity

A menu should make choices clear before it tries to direct attention

A practical menu has a readable type size and contrast, clear sections, consistent item names, concise descriptions and a layout that works on paper and on a phone. Accurate prices, dietary information and allergen guidance support informed choice. The design should fit the restaurant and its customers, but visual style should not make important information hard to find.

Boxes, borders, colour, type changes and images can act as ‘eye magnets’ by drawing gaze toward an area. Pavesic (2005) discusses these as menu-design recommendations. They are not proof that a highlighted item will be ordered: attention, liking, choice, sales and profit are different outcomes.

Too many highlights, small print, clutter, misleading photographs or unclear categories can increase search effort and reduce legibility. A menu may be tested by comparing one design feature at a time. Eye-tracking can record fixations and scanpaths; researchers should also record item choice or orders and ask customers how clear the menu felt.

A fixation is evidence of where the eyes paused, not a direct measure of understanding, preference or purchase. Eye-tracking results depend on the task, menu format, hunger, familiarity and the participant’s goal. Pair gaze data with behaviour and self-report instead of treating it as a complete explanation.

Dayan and Bar-Hillel (2011) tested position in simultaneous printed menus

Primacy and recency usually refer to an advantage for items encountered first or last in a sequence. A printed menu presents category items together, so choosing a first or last item can also reflect spatial position or a preference for items near the edges. Dayan and Bar-Hillel tested this distinction rather than assuming the familiar serial-memory effect would apply.

In Study 1, 240 Hebrew University students were randomly assigned to one of four printed-menu orders. The menu offered the same foods and descriptions, with no prices; participants chose one item from each category. Items near the beginning or end of a category were chosen more often than the same items in the middle. The researchers reported an overall edge advantage, but no top-half versus bottom-half advantage: the result was not evidence of a simple primacy or recency effect.

Study 2 alternated a standard café menu and a version changing item positions, then recorded real orders in three categories. The overall edge-position advantage was similar, though category-level evidence was not equally strong for every category. The real café orders add everyday relevance, but customers, preferences and service conditions were not controlled like a laboratory task.

The studies concern the menus and restaurants tested, not every cuisine or digital interface. Study 1 used hypothetical selections without prices; Study 2 recorded actual orders but only at one café. A retailer should test its own menu and customers rather than assuming that putting an item at an edge will always increase sales.

Lockyer (2006) examined how words shape menu choice

Lockyer used four focus groups to compare five menus containing the same items but different wording, then used the focus-group themes to develop a broader survey. Participants discussed the dining occasion, companions and the appeal of dishes they might not make at home. Descriptive words such as ‘tender’, ‘golden’ and ‘natural’ were viewed positively in the survey.

The work provides both qualitative comments about why wording appeals and survey responses about preferred choices. It supports the idea that a menu description can shape expectations and stated selection. It does not establish that any particular adjective causes more purchases in every restaurant: language, food familiarity and occasion may differ, and a survey choice is not the same as a recorded order.

Descriptions should be vivid but accurate. A field test can compare two truthful descriptions of the same dish while keeping price and placement constant; record actual orders and ask a separate rating question. Do not use wording that misrepresents ingredients, origin, dietary suitability or portion size.

Match each method to the question

Eye-tracking is useful when the question concerns what a diner looks at and in what order. A questionnaire can ask what seems clear, appealing or confusing. A controlled menu task can isolate one design variable, while a field experiment can test real orders in a restaurant.

Objective outcomes include first fixation, time to locate an item, choice and recorded orders. Subjective outcomes include ratings and comments. Neither type alone answers every question: a diner can look at a dish without choosing it, and a stated preference may differ from a purchase.

A valid test changes one feature, uses comparable dishes and prices, includes a suitable comparison menu and records the same outcomes. Random assignment strengthens a causal claim; an uncontrolled before-and-after sales comparison may be affected by day, season, stock, price or customer mix. Results from one sample or restaurant should be generalised cautiously.

Pause and explain

Which result did Dayan and Bar-Hillel report across their two menu-position studies?

Put the idea to work

Worked example

A café owner says, ‘We put a dish in the first position, so Dayan and Bar-Hillel prove customers will order it because of primacy.’ Correct the explanation.

Show the worked solution
  1. Distinguish sequential primacy from choices among simultaneously displayed items.
  2. State what the two menu studies found about edge positions.
  3. Name one outcome or design limitation before recommending a local test.

Answer Dayan and Bar-Hillel studied item position in printed menus where options were displayed simultaneously. Their results showed an edge-position advantage over middle positions, but no clear top-half versus bottom-half advantage, so the findings do not show a simple primacy effect. Study 1 used no-price hypothetical selections; Study 2 recorded orders at one café. The café should test its own menu while holding prices and dishes constant and recording actual orders.

From guided practice to a new situation

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.

1 · Guided

A restaurant wants to know whether a small box around one dish draws attention and increases orders. What should it measure, and what should stay separate?

Give me a hint

Measure gaze and orders as two outcomes.

Compare my reasoning
  1. Use comparable menus that differ only in the box around the target dish, with the same dishes, descriptions and prices.
  2. Use eye-tracking to record fixations or time to first fixation, then separately record the dish selected or ordered.
  3. Ask diners whether the menu was clear in a separate rating; a gaze change alone does not prove better understanding or more orders.

Compare matched menus with and without the box, keeping other details fixed. Record gaze, actual choice or orders, and menu clarity as separate outcomes; do not treat attention as proof of purchase.

Look for these in your work

  • Menu manipulation isolated
  • Gaze and orders separated
  • Subjective clarity measured separately
2 · Independent

Evaluate: ‘Dayan and Bar-Hillel proved that the first and last dish always sell best because of primacy and recency.’

Give me a hint

Use the simultaneous display, the observed position pattern and a limitation.

Compare my reasoning
  1. Printed menu options were displayed together, unlike items encountered one after another in a serial-memory test.
  2. Their studies found a general advantage for edge positions over middle positions, but no simple top-half versus bottom-half advantage.
  3. One study used no-price selections by students; the café field study concerned one site and categories. Neither proves a universal sales rule.

The conclusion confuses a spatial edge effect with primacy and recency. Dayan and Bar-Hillel found that edge-position items were generally chosen more than middle items, but did not find a simple first-over-last or top-half advantage. The laboratory menu had no prices and the real-order study was at one café, so the effect needs local testing.

Look for these in your work

  • Position and serial effects distinguished
  • Result stated accurately
  • Study limits named
3 · Transfer

A school canteen is considering two truthful descriptions for the same vegetarian lunch. Design a field test that uses Lockyer’s findings but checks actual behaviour fairly.

Give me a hint

Keep the dish, price and availability unchanged; collect both an order measure and a response.

Compare my reasoning
  1. Use two accurate descriptions of the same dish and alternate or randomly assign the menu version across comparable service periods.
  2. Keep price, portion, position, stock and serving conditions constant; record how many portions are ordered in each condition.
  3. Ask a short optional question about clarity or appeal, and account for day, menu familiarity and limited stock before interpreting a difference.

A fair field test changes only the wording, keeps the meal, price, position and availability stable, and records actual orders. A separate optional rating can explain whether diners found the description appealing; results across comparable periods are more useful than one busy lunch.

Look for these in your work

  • Only wording changed
  • Actual orders recorded
  • Subjective response and confounds considered

Common mistakes

  • Calling every first-position advantage primacy when menu options are visible at the same time
  • Treating a fixation or an attractive rating as an actual order
  • Claiming Lockyer proved that a descriptive word always increases sales
  • Assuming one menu layout or eye-magnet placement works for all readers and devices
  • Changing position, price, description and item availability at once, making the cause unclear
Recall without your notes

What can you explain now?

Why is an edge-position effect in a printed menu not automatically a primacy or recency effect?

Compare with the explanation

Menu items are displayed simultaneously; primacy and recency usually describe first or last exposure in a sequence.

A spatial location effect and a serial-order memory effect are distinct explanations and need different tests.

Course scope and assessment

Seven original lessons map all 15 AS research-method and methodological-concept sections to explained Guided, Independent and Transfer practice. All 12 compulsory AS core studies have original study-specific teaching and staged practice; five additional A Level methodology lessons cover research design and validity. All 15 Clinical, all 15 Consumer (2.1.1–2.5.3) and all 15 Health (3.1.1–3.5.3) Psychology sections link to original teaching and staged practice. All 15 Organisational Psychology sections 4.1–4.5 now have original teaching and explained staged practice; the six new 4.4–4.5 lessons bring the planning map to 92 of 92 indexed sections. Consumer lessons cover physical and psychological environments; decision models, heuristics and mistakes; packaging, selling and buying; advertising, self-monitoring, product placement, brand recognition and slogans. Evaluation boundaries are explicit: studies use particular products, samples, tasks and settings; gaze, recall, self-report, EEG indices, ratings, choices and purchases are different outcomes. Health evidence is bounded: Laba et al. measured hypothetical preferences; Riekert and Drotar raise a non-response concern; Chung and Naya's cap tracked openings, not swallowing; Chaney et al. was a short caregiver-reported pilot; Yokley and Glenwick examined immunisation attendance in one public-health setting. MacLachlan et al. report one patient, not a controlled treatment effect; Brudvik et al. compared separate child, parent and physician ratings in one emergency department. Chandola et al. found a cohort association; Wang et al. measured responses during a monitored arithmetic task; Evans and Wener observed commuters; Bridge et al. found mixed self-rated outcomes in radiotherapy. Janis and Feshbach measured short-term self-reports in one school; Lewin et al. tested a rehabilitation package, not information alone. Tapper et al. and Fox et al. studied bounded school and worksite programmes; incentive effects do not establish transfer or rule out reporting effects. Weinstein measured comparative expectations, while Seligman’s framework is conceptual and Shoshani and Steinmetz used a school-level comparison. These findings do not establish universal health effects or diagnose individuals. Need-theory examples use a child measurement study, not a workplace test; SMART is a practical checklist, not a motivational theory. Landry et al. compared reward framing with student volunteers in a lab; this does not establish universal effects in workplaces. Cuadrado et al. (2008) measured undergraduate evaluations of presented leaders, not workplace performance or hiring; this does not establish a universal gender effect. The historical 1995 Munchausen criteria are not a current diagnostic checklist. Cambridge’s 2028–2030 Reference List treats Oruč et al. (1997) as an example of genetic explanation although its participants had bipolar I; gambling disorder is listed in Cambridge’s Clinical topic but classified under addictive behaviours in ICD-11. Candidates choose two options, but all four remain listed so schools can select a route. The 92-section count is a planning index, not a Cambridge score. Remaining work is deeper coverage review, separate-year syllabus reconciliation, timed-paper practice and human subject-expert review. The separate 2027 and 2024–2026 syllabuses are not reconciled into this route. Practice is not official grading, a timed-paper simulation or human subject-expert review.
