Aberdeen Psychology PhD: Developmental and EEG Studies of Space, Time and Number

Aberdeen Psychology PhD: Developmental and EEG Studies of Space, Time and Number

Research question and applicant decision

This project tests whether space, time and number share one magnitude system or use distinct overlapping mechanisms, combining child development with EEG N2pc, classification and RSA. The work is relevant to quantitative psychology/cognitive-neuroscience backgrounds, including computing applicants willing to work with participants and learn MATLAB. Its strength is converging developmental/neural comparisons; its central uncertainty is the unpublished age/design, recruitment and task-control plan. Four-year international EASTBIO funding is competitive, with overseas-fee waivers for successful international awardees and an estimated £22,437 for 2027/28. Discuss the first theory-discriminating comparison, then ensure the application and both references arrive by 16 November 2026, 23:59 GMT; part-time is Home/UK only. Current acceptance status has not been confirmed.

Research Problem and Doctoral Work

Estimating distance, duration and numerosity helps organisms navigate, forage and make decisions. The open question is whether these abilities use one common magnitude representation or distinct specialised systems with some overlap. The doctorate tests common-process versus distinct-process hypotheses through two converging approaches, rather than assuming that similar behaviour means identical neural machinery.

First, child developmental studies assess how space, time and number abilities develop together and how their co-dependency changes. The advertised common-process prediction is co-development at the same rate. Second, EEG examines shared signatures and neural co-dependency through univariate N2pc, multivariate classification and representational similarity analysis (RSA). A common system predicts shared magnitude signatures/dependencies that do not extend indiscriminately to non-magnitude domains such as working memory and language. These comparator domains are part of the scientific design, not optional background. Training explicitly includes working with children, implementing EEG experiments, analysing data and MATLAB programming.

Interpretation needs more than a correlation or successful classifier. Age, general ability, task difficulty, reliability and response strategies can create shared developmental patterns; cross-sectional age differences do not themselves establish within-child developmental change. Shared EEG patterns can reflect attention, visual features or motor demands rather than magnitude coding. N2pc, classification and RSA measure different aspects of signals; none uniquely identifies a brain mechanism. A defensible plan should distinguish common representational content from shared task demands, use appropriate validation and assess uncertainty. These are analytical discussion points, not additional advertised procedures.

Two independent studies show why the problem remains active. Mieulet and colleagues, Scientific Reports 15:39511, 11 November 2025, analysed EEG from 30 participants: CNV/LPC indexed relative duration or distance when that dimension was task-relevant. This supports domain-general task-relevant processing but did not test number, children or this project's N2pc hypothesis. Hallez and Balcı, Scientific Reports 14:10377, 6 May 2024, studied 82 children aged 5–7; space–time biases decreased with age and short-term memory predicted interference. This makes memory a substantive comparator, but a predictive association is not proof of a universal single system or a causal developmental pathway. Independent EEG evidence; Child development evidence.

Exact age range, cross-sectional versus longitudinal design, whether EEG includes children, sample size, task battery, preregistration plans and data already available are unpublished. Potential outputs are validated developmental/EEG comparisons and reproducible analyses that discriminate hypotheses; a diagnostic test, educational intervention or particular publication outcome is not promised.

Career directions

Transferable routes include cognitive/developmental research, quantitative behavioural work, human-centred research and broader data analysis. NCS gives £28,000–£65,000 for the broad data analyst-statistician occupation, not a project graduate salary or hiring probability. This doctorate does not itself grant clinical/educational psychology practice rights. Career evidence.

School, Programme and Field Context

The School of Psychology is the advertised host, and the University of Aberdeen is the expected degree-awarding institution. Its cognition, perception/attention and social-cognition themes provide relevant context; this project sits particularly close to perception and numerical cognition. EASTBIO is a training/funding network, not a second degree-awarding university. The SMMSN email is the competition's administrative submission route, not evidence that registration is in Medicine. Exact 2027 degree/code, start date and local review milestones remain unconfirmed. School research context.

The official REF 2021 UoA4 Psychology, Psychiatry and Neuroscience profile reports 34% four-star, 60% three-star, 25.00 FTE. This is a relevant unit-level research assessment, not a world ranking or a score for these supervisors. Shared EEG and language/number facilities plus current peer-reviewed perception/numerical work are more direct project signals; no exact current subject world-ranking claim is established. REF 2021 subject evidence.

EASTBIO funds four years full-time; this project also permits part-time study for Home/UK students only. Student-visa holders must study full-time and usually live within commuting distance. Core interdisciplinary/professional training concentrates in years 1–2. Standard PIPS is 12 weeks in a non-academic organisation before the end of year 3, outside the student's PhD research. This is not a CASE advert. The 2026/27 calendar does not establish final 2027 arrangements. Training; PIPS.

The school's generic PhD page describes online admission, a 1–2 page proposal and two academic referees; this EASTBIO call instead specifies the email form, no proposal and permits one non-academic referee. Use the competition rules first; confirm later university registration steps if selected. The official EASTBIO 2027 route directs applicants to its designated project directory. The available materials do not establish a separate Aberdeen-hosted page for this listing; that does not establish closure or current availability. School generic PhD route; Current official entry; University opportunity gateway.

Supervisors, Recent Papers and Resources

Ramakrishna (Rama) Chakravarthi is a Senior Lecturer in Psychology, with current work in visual perception, crowding, EEG and temporal judgement. Alexandra Cleland, also a Senior Lecturer, researches numerical/spatial associations. The Language and Number Lab's official record calls its manager Sandie Cleland, links the Alexandra profile and names Alexandra in its contact field. Thus the project's Dr S. Cleland has an official alias cross-reference rather than evidence of a separate third supervisor. Formal project roles and supervision fractions remain to be confirmed. Chakravarthi official profile; Cleland official profile; Official Sandie/Alexandra cross-reference.

Four recent primary studies are particularly useful:

Cleland and Bull: spatial–numerical associations

Cleland and Bull, Journal of Experimental Psychology: Learning, Memory and Cognition, 2026, DOI 10.1037/xlm0001611: six studies show that spatial–numerical response associations in colour decisions depend on familiar structured arrangements or quantity-congruent visual area; some effects are weak by Bayesian standards. It directly motivates separating number from low-level visual cues. It does not show a universal magnitude system, developmental trajectory or EEG mechanism. Earlier 2026 accepted/online records refer to the same paper and are not separate outputs. 2026 numerical cognition paper

Bibliography: Alexandra Cleland; Rebecca Bull. Spatial-numerical associations with non-symbolic representations of quantity: Evidence from color decision. Journal of Experimental Psychology: Learning, Memory and Cognition (2026). DOI: 10.1037/xlm0001611. The institutional record labels 13 October, while PubMed indexes 27 April 2026 ahead-of-print with nonsymbolic and Alexandra A Cleland. Same DOI, not separate outputs; publisher byline/date and final volume/pages remain unresolved.

Silver and colleagues: temporal-measurement differences

Silver, Tatler, Chakravarthi and Timmermans, Consciousness and Cognition 140:104022, 2026: two experiments yield different, sometimes opposite temporal-binding patterns for online estimation versus replication. This makes method comparability and technical timing central, but online action–outcome judgements are not child magnitude EEG. The project should not treat every time-perception measure as interchangeable. 2026 temporal-methods paper

Bibliography: Crystal A. Silver; Benjamin W. Tatler; Ramakrishna Chakravarthi; Bert Timmermans. Method matters: Diverging patterns in online measures of temporal binding. Consciousness and Cognition 140:104022 (2026). DOI: 10.1016/j.concog.2026.104022. Online 19 February 2026; April issue; institutional abstracts only.

Soo and colleagues: visual EEG evidence

Soo, Antonov, Chakravarthi and Andersen, Journal of Cognitive Neuroscience 38(1):1–14, January 2026, online 18 July 2025: two SSVEP experiments connect target/flanker spacing and similarity with both behavioural performance and cortical signal suppression. This evidences EEG/psychophysics capability, while SSVEP is different from the advertised N2pc and the study does not establish numerical representations. 2026 visual EEG paper

Bibliography: Leili Soo; Plamen A. Antonov; Ramakrishna Chakravarthi; Søren K. Andersen. Suppressive Interactions between Nearby Stimuli in Visual Cortex Reflect Crowding. Journal of Cognitive Neuroscience 38(1):1–14 (2026). DOI: 10.1162/JOCN.a.79. A cross-check of official author records corrects the duplicated institutional Antonov Antonov to Plamen A. Antonov; 18 July 2025 online and January 2026 issue are one paper, abstract-level only.

Papadaki and colleagues: separating visual and decision processes

Papadaki, Chakravarthi and Andersen, Journal of Experimental Psychology: Human Perception and Performance 52(4):424–439, 2026, online 1 April: two experiments find opposite inner–outer asymmetries for visual crowding and decision-stage flanker effects despite other shared spatial patterns. The methodological lesson is that superficial similarity can mask distinct processes; these adult visual tasks still do not decide the developmental magnitude question. 2026 process-dissociation paper

Bibliography: Danai Papadaki; Ramakrishna Chakravarthi; Søren K. Andersen. Distinct spatial patterns of flanker interference differentiate visual crowding from flanker compatibility effects in the Eriksen task. Journal of Experimental Psychology: Human Perception and Performance 52(4):424–439 (2026). DOI: 10.1037/xhp0001413. The saved Aberdeen record labels the issue May, while SDU and another index give April 2026. Because the month remains unresolved, cite 2026 and 52(4):424–439 without claiming a uniquely verified issue month. Abstract-level only.

The Psychophysiology Centre lists shielded booths, 64- and 128-channel Biosemi ActiveTwo, external eye/muscle recording and an analysis computer, with shared booking. Chakravarthi is recorded as manager while descriptive text calls Soren Andersen coordinator; confirm current support contacts. The Language and Number Lab lists three Eprime PCs, response boxes and portable audio tools, and broader links to special populations including schools. These are relevant capabilities, not this student's guaranteed equipment slots, a recruitment cohort or a promise to use every device.

Ask about daily MATLAB/EEG mentorship, allocation between developmental and neural studies, supervisor capacity, school partnerships and participant reimbursement. Child recruitment needs appropriate ethics, consent/assent and age-appropriate burden; current access permissions and usable data are not published. No exact-project graduate outcomes or supervision meeting frequencies were located. EEG facilities.

Funding, Application and Living Cost

EASTBIO instructions also make the anonymous Equality, Diversity & Inclusion (EDI) survey mandatory: copy its unique response ID onto the application form. The survey is open from 4 October to 17 November, but that does not extend the application and reference deadline of 16 November. References from the project supervisor(s) are not accepted. EASTBIO current application requirements

Eligibility and funding

The project advertises four-year competitive funding, estimated £22,437 for 2027/28, a research/training grant of £5,000 annually in years 1–3 and £1,500 in year 4, plus £230 annual travel/conference support. The latter are research budgets, not extra living stipend. UKRI's current formal minimum is £21,805 from 1 October 2026; the 2027 amount requires confirmation. UKRI.

EASTBIO permits international applicants to compete; international students are capped at 30% of annual recruitment across the entire network, not a per-project quota or an individual award probability. Successful international awardees receive an overseas tuition top-up waiver. A China-based applicant who does not meet Home-status rules can compete, but eligibility is not an award. Visa/IHS are excluded. Visa holders must study full-time and normally live within commuting distance; the project's part-time option is Home/UK only. Confirm fee coverage throughout the funded period, stipend increases and interruption/extension terms. Funding FAQ.

Application and timing

Contact the lead supervisor before applying. Apply to one EASTBIO project only. Submit one email to smmsn-pgrenquiries@abdn.ac.uk, subject “EASTBIO Application – [Your Name]”, containing the EASTBIO form, university-level certificates/transcripts and two official-form references; one reference may be non-academic. Referees may send directly using “EASTBIO Reference – [Your Name]”. Both references and the application must arrive by 16 November 2026, 23:59 GMT.

No proposal, extra CV, school certificates, conference papers or dissertations should be added. Incomplete or unnecessarily supplemented applications will not be considered; applicants must ensure references arrive because the university does not chase missing documents. Receipt confirmation may come after the deadline; do not chase status. The host-specific deadline takes priority over general FAQ flexibility.

The current timeline gives 18 January supervisor nominations, 22 February interview invitations, interviews in the week of 8 March, and decisions in the week of 22 March 2027. The standard process normally nominates one candidate per project. Interview preparation should include a short account of previous research, its limitations and interest in interdisciplinary training. Nomination is not a scholarship offer. Selection.

Living costs

Official 2026/27 Aberdeen housing examples include Adam Smith House £111/week, Elphinstone Road £133/week with a shared bathroom / £191/week ensuite, and South House £147/week with a shared bathroom / £191/week ensuite, with selected 40–50-week leases. Wi-Fi is listed; room eligibility, utilities and full-year coverage require checking. These are not 2027 reservations. Housing fees, housing gateway.

Aberdeen's recommended rent-inclusive minimum is £1,171/month, or £14,052 over 12 months. An estimated 2027 stipend and older minimum budget cannot establish future savings. The benchmark follows UKVI minimum guidance rather than measured average spending. Do not count rent twice. Deposits, relocation, visa/IHS, inflation, research-related travel and PIPS costs must be included in actual planning. Obtain 2027 quotes and preserve start-up liquidity. University budget guidance.

Applicant Fit and Preparation

Required academic eligibility: a relevant UK 2:1 or international equivalent; 2:2 can be considered with achieved/expected Master's Distinction or Commendation. The project welcomes Psychology, Cognitive Science, Neuroscience, Biology, Computer Science or related fields. It seeks enthusiasm for neural/developmental cognition and willingness to train in working with children, EEG implementation/analysis and MATLAB. These are training commitments; the advert does not say that prior mastery of every method or previous child research is mandatory. A computational background is relevant but does not remove participant-facing work.

Aberdeen Psychology uses Postgraduate Standard: IELTS Academic 6.5 overall, writing 6.0, reading/listening/speaking 5.5; valid One Skill Retake is accepted and evidence normally must be within two years of entry. Do not import SMMSN's Higher reading requirement because of the submission email. Confirm 2027 language evidence/exemptions and Chinese degree equivalence. Current Psychology English band.

Useful analyst-suggested preparation is a reproducible behavioural or EEG analysis explaining reliability, confounds, validation and what result would distinguish common from distinct systems. MATLAB familiarity and statistical reasoning help; an account of ethical participant work and teamwork also matters. Quantitative preparation should serve the theoretical comparison rather than an unmotivated classifier. A research proposal is not required and additional proposal/CV documents must not be appended.

Next Actions and Questions to Verify

Before Applying

Contact Chakravarthi about the initial magnitude tasks, clarify Cleland's project role and confirm qualification equivalence/Psychology English. Arrange the single permitted EASTBIO application and two official-form references for 16 November 2026, 23:59 GMT. The full-time route is the relevant route for a China-based applicant requiring a Student visa.

At Interview

Ask which age groups and design establish developmental co-dependency; whether EEG is collected from children or adults; and how working-memory/language comparators, difficulty and visual/motor demands distinguish theories. Clarify N2pc, classification and RSA priorities, pilot data/reliability, samples, child recruitment/ethics readiness and delayed-recruitment fallback. Establish daily MATLAB/EEG support, equipment allocation, supervision fractions and current student capacity.

Before Accepting an Offer

Obtain the exact 2027 start, degree/code and review milestones; final stipend and four-year international fee waiver; participant/research/travel/PIPS and extension terms. Confirm visa/IHS and start-up funds, full-year housing and any school-travel cost. The most useful immediate action is a short discussion of a comparison that could distinguish shared magnitude content from shared task demands.

Evidence and Sources

All four supervisor-paper discussions are limited to abstracts and bibliographic metadata rather than full-text scientific assessment, as scoped in the relevant sections. The FAQ and Psychology English requirements should be checked against current official guidance. Current project availability and individual 2027 award terms have not been confirmed.
