Recording and Presenting Evidence in a Psychology EE
Why recording evidence matters
In Psychology, the evidence forms the foundation of your entire extended essay.
Unlike laboratory sciences where you can record primary data, in Psychology all evidence comes from secondary sources.
This means your task is not to generate new data but to demonstrate that you can select, present, and evaluate published research in a way that builds a sustained argument.
Tip
The way you summarise and interpret that research will directly determine how examiners judge your achievement in Criterion C (analysis and argument) and Criterion D (discussion and evaluation).
Recording evidence is not about compiling every detail from every study. It is about showing that you understand which aspects of the research are central to your question.
Example
For instance, if your essay explores the relationship between social media use and body image, you do not need to reproduce the entire method of each study you cite.
Instead, you need to highlight the parts of the study that are relevant:
How the construct of body image was operationalised
The population that was investigated
The type of method used
The main findings that connect to your research question.
Quantitative and qualitative evidence
Psychological research can be quantitative, qualitative, or mixed-methods.
Tip
Both forms of evidence can be included in an EE, but they must always be interpreted rather than listed.
Quantitative findings might include statistics such as correlation coefficients, effect sizes, or group means.
When reporting these, use the numbers to illustrate the strength and direction of an effect, but immediately explain what they mean in psychological terms.
Example
“Fardouly et al. (2015) found a significant correlation between time spent on Facebook and body dissatisfaction in adolescent girls (r = .30).
This suggests that heavier social media use is moderately associated with negative self-perceptions, supporting the idea that online environments intensify social comparison.”
Qualitative findings might include themes from interviews, open-ended surveys, or observational studies.
These should be paraphrased in your own words and tied back to your research question.
Example
“Tiggemann and Slater (2014) used thematic analysis of interview data and identified appearance-focused conversations as a recurring theme.
This qualitative finding helps explain how peer influence may amplify the visual emphasis of social media platforms, which in turn contributes to body image concerns.”
In both cases, evidence is presented not as raw data but as interpreted information that advances your essay’s argument.
How much detail is enough?
Common Mistake
A common weakness in Psychology EEs is including either too much or too little detail.
Too much detail leads to pages of description that examiners view as narrative rather than analysis.
Too little detail makes it impossible to understand how the evidencesupports the argument. The key is balance.
When writing about a study:
Include who was studied (population, sample).
Explain what was measured (constructs and operationalisations).
Summarise how it was studied (methodological approach in brief).
Report what was found (main results, patterns, or themes).
Analyse why it matters (connection to your research question and theory).
Tip
This structure ensures that every study you record has both context and purpose in your essay.
From description to analysis: weak vs strong writing
To see the difference, compare these two ways of presenting the same study:
Example
Weak (descriptive):
Sherman et al. (2016) studied adolescents using fMRI and found that participants’ reward centres were activated when their photos received more likes. The study concluded that social media likes influence neural responses.
Example
Strong (analytical):
Sherman et al. (2016) used fMRI with adolescents and found increased activation in reward-related brain regions when participants’ photos received more likes. This shows that social approval on social media can engage neural mechanisms similar to those activated by primary rewards. This supports the view that digital feedback contributes to reinforcing behaviour, helping to explain why adolescents may be particularly sensitive to online approval in ways consistent with principles of reinforcement learning.
The strong version records the evidence but also interprets and links it to psychological theory, moving beyond description to analysis.
Integrating multiple studies
As the EE is not just a literature review, presenting evidence requires you to synthesise multiple studies rather than summarising them in isolation.
Example
Becker et al. (2002) showed that the introduction of television to Fiji was associated with an increase in reported eating disorder symptoms among adolescent girls, suggesting that media exposure influences body ideals. Similarly, Fardouly et al. (2015) found that time spent on social media correlated with body dissatisfaction in Australian adolescents. Together, these findings suggest that both traditional media and newer digital platforms can amplify cultural pressures around body image, lending support to the sociocultural model of eating disorders.
Here, two studies are recorded, compared, and tied into a broader theoretical framework.
Tip
This kind of integration shows examiners that the student can process evidence into a line of argument.
Example
Worked example: Loftus & Palmer
Weak (descriptive):
Loftus and Palmer (1974) found that participants estimated higher speeds when asked how fast cars were going when they ‘smashed’ rather than ‘hit’ each other. This shows that memory can be influenced by wording of questions.
Strong (analytical):
“Loftus and Palmer (1974) demonstrated that eyewitness memory can be reconstructed based on leading questions, supporting the idea that recall is not a simple retrieval of stored events but a reconstructive process. However, demand characteristics may have influenced the results, as participants could have guessed the aim of the study. This raises questions about ecological validity, since memory for real accidents may not be as easily manipulated. Comparing these findings with Yuille and Cutshall’s (1986) real-life crime study highlights the importance of context: while Loftus and Palmer suggest memory is highly malleable, naturalistic evidence shows that emotional salience and real-world settings may produce more reliable recall. Taken together, these findings suggest that memory is reconstructive, but the extent of distortion depends on context.”
This shows how to move from reporting a finding to evaluating its strengths, weaknesses, and relevance to the RQ.
The role of theory in presenting evidence
Evidence in Psychology is rarely self-explanatory. Its significance emerges when it is placed in the context of a theory or model.
For example, schema theory can explain why memory distortions occur, while social comparison theory can explain why body dissatisfaction increases with exposure to idealised images.
Tip
Every time you record evidence, ask:
Which theory does this relate to?
How does it strengthen or challenge the theoretical perspective I am using?
Students who present evidence without linking it to theory risk producing an essay that feels like a list of findings.
Tip
Students who consistently tie findings to theory demonstrate the deep understanding expected for top marks in Criterion B and C.
Bias, error, and uncertainty in psychology
Just as scientists in labs account for measurement error, psychology students must acknowledge the biases and limitations in the research they use.
These influence how confidently findings can be interpreted.
Example
Demand characteristics (Loftus & Palmer, 1974): Participants may have changed their answers to fit perceived expectations.
Cultural bias (Asch, 1951): High conformity in 1950s America was not reproduced in later cross-cultural studies, limiting universality.
Ecological validity (Bandura et al., 1961): Children in a lab may not behave the same way in real-life social environments.
Ethical constraints (Becker et al., 2002): Researchers cannot expose participants to harmful influences, so causal claims are limited.
Using case studies like these demonstrates evaluative skill.
Using language precisely
Subject-specific terminology is part of how you “record” evidence in Psychology.
Words such as operationalisation, ecological validity, demand characteristics, bidirectional ambiguity, reliability, and triangulation are not just jargon (they are tools for conveying the quality of the evidence).
Accurate and consistent use of terminology is essential.
Example
For instance, saying that a study “proves” a theory is inaccurate; instead, you might write that a study “supports” or “provides evidence consistent with” a theory.
Handling contradictory findings
Psychological research often contains studies with opposing results.
Strong essays explicitly acknowledge and interpret these contradictions rather than ignoring them.
Contradictory outcomes might be due to cultural context, sample differences, or measurement methods.
Example
For instance, some studies suggest that media use strongly affects body image, while others report only weak correlations.
Acknowledging this inconsistency and offering explanations strengthens the analysis.
Reliability and validity trade-offs
Reliability and validity in psychology play a role similar to accuracy and precision in the sciences.
Reliability refers to whether a finding can be replicated. Large, well-controlled studies often achieve high reliability.
Validity refers to whether the studymeasured what it claimed to measure and whether findingsgeneralise beyond the sample.
Example
For instance, laboratory studies often achieve strong reliability but may have weak ecological validity.
Case studies, meanwhile, provide high validity in context but are less replicable.
Recognising these trade-offs demonstrates critical understanding of the evidence base.
Common pitfalls in presenting evidence
Over-description: Giving every procedural detail of a study instead of focusing on findings relevant to your research question.
Cherry-picking: Citing only studies that support your argument without acknowledging contradictory evidence.
Weak linkage:Summarising results without explaining their relevance to theory or to your specific RQ.
Over-reliance on one source: Depending too heavily on a single study or secondary summary instead of engaging with multiple peer-reviewed sources.
Checklist for recording evidence in paragraphs
When writing a study summary, make sure each paragraph includes:
Researcher(s) and year (with citation).
Participants or context.
Methodological approach in brief.
Main findings (quantitative or qualitative).
Evaluation (strength, limitation, or link to theory).
Connection to the research question.
If any of these elements are missing, your recorded evidence may come across as descriptive rather than analytical.
Final reflection on recording evidence
Recording evidence in a Psychology EE is not about copying details from articles but about showing you can select, interpret, and connect research in a way that advances your argument.
Each paragraph should feel like a small piece of reasoning that builds toward your overall answer to the research question.
Hint
Done well, this approach ensures that your essay reads as a critical investigation rather than a descriptive report.
Processing Evidence and Developing Argument in a Psychology EE
From evidence to argument
Once evidence is gathered and recorded, the real work of the Psychology EE begins: transforming those summaries into an argument.
Examiners are not looking for a catalogue of studies; they are looking for a line of reasoning that responds directly to the research question.
“Processing” evidence means showing the reader how the studies fit together, where they agree or conflict, and what conclusions can be drawn.
A strong EE constantly asks:
How does this studyanswer my research question?
What pattern emerges when I compare it with other studies?
Which theory best explains the pattern?
What gaps or contradictions limit the strength of my argument?
Tip
By weaving these questions into every section of analysis, the essay moves from description to critical engagement.
Organising analysis thematically
One of the most effective strategies is to organise the essay into themes rather than study-by-study summaries.
Each theme should represent a piece of the argument.
For example, in an essay on social media and body image, themes might include exposure to idealised images, peer comparison processes, and protective factors such as media literacy.
Within each theme, the student then integrates multiple studies, showing both their findings and their limitations.
Example
Exposure to idealised body images has consistently been linked to body dissatisfaction in adolescents. Becker et al. (2002) found that the introduction of television in Fiji was associated with increased eating disorder symptoms, demonstrating the powerful effect of media imagery. Fardouly et al. (2015) extended this finding to digital platforms, reporting a positive correlation between Facebook use and body dissatisfaction. However, Ferguson et al. (2014) found only a small effect in a large longitudinal sample, suggesting that individual vulnerability factors may moderate this relationship. Together, these studies support the sociocultural model but also highlight the need to account for individual differences when interpreting media effects.
This single paragraph shows synthesis: multiple sources are compared, theory is referenced, and nuance is introduced.
Using theory as the backbone
Theories and models provide the glue that holds the essay together.
Without them, paragraphs risk becoming disjointed summaries.
Using theory as a backbone means consistently asking: What does this evidence show about the theory, and what does the theory predict about this evidence?
Example
In memory research, schema theory predicts that prior knowledge shapes recall.
When citing Loftus and Palmer (1974), the analysis should show how the study illustrates schema-driven distortion, and whether later replications or challenges strengthen or weaken this claim.
In abnormal psychology, the cognitive model predicts that maladaptive thought patterns maintain depression.
Studies on cognitive-behavioural therapy can then be analysed in terms of how they support or challenge this theoretical explanation.
Hint
Theories prevent the essay from drifting into unrelated results and keep the discussion anchored in psychology.
Comparative analysis: building tension and balance
A high-level EE demonstrates the ability to compare evidence. This can be done by:
Confirming convergence – showing how different studies point to the same conclusion.
Highlighting divergence – identifying contradictory findings and exploring why they differ.
Explaining nuance – showing that effects depend on context, culture, or population.
Example
While Sherman et al. (2016) found that social approval on Instagram activated reward-related brain regions in adolescents, Odgers and Jensen (2020) concluded that overall links between social media use and adolescent mental health are weak and inconsistent. The difference may lie in the level of analysis: neural responses may capture immediate reinforcement processes, whereas survey-based studies may underestimate these effects over time. This contrast illustrates the complexity of linking brain-level findings to broad behavioural outcomes.
Such comparisons demonstrate analytical maturity and are rewarded under Criterion C.
Paragraph templates for analysis
Example
Weak paragraph (descriptive):
Loftus and Palmer (1974) investigated the effect of leading questions on memory. They showed participants a car crash video and asked about the speed of the cars. Depending on the verb used, participants’ speed estimates differed. This shows that memory can be distorted by language.
Example
Strong paragraph (analytical):
Loftus and Palmer (1974) demonstrated that leading questions influence eyewitness memory, with participants giving higher speed estimates when the verb ‘smashed’ was used. This supports the idea that recall is not a direct record of events but is reconstructed based on schema-consistent cues. However, the artificial setting raises concerns about ecological validity, as real eyewitnesses may experience higher stress and different attentional processes. The study therefore provides strong experimental evidence for schema theory but has limited generalisability to real-world testimony.
The second version processes the evidence into argument, balancing strengths, limitations, and theoretical significance.
Avoiding the “study shopping list”
One of the biggest pitfalls is the “shopping list” essay (where each study is presented in sequence with minimal connection between them).
Example
For instance: “Study A found this. Study B found that. Study C found another thing.”
This approach feels repetitive and lacks synthesis.
Instead, students should cluster studies around themes and use linking phrases:
“This finding supports…”
“In contrast to…”
“Taken together, these results suggest…”
“However, other research challenges this conclusion by showing…”
Such linking phrases demonstrate that the student is processing evidence, not just listing it.
Handling qualitative evidence
Qualitative studies must also be analysed critically.
Example
Willig (2000) interviewed women with eating disorders and identified themes of control and identity. These insights highlight lived experience that cannot be captured in quantitative surveys. However, qualitative methods rely heavily on interpretation, and researcher bias may shape the themes identified. Triangulating qualitative findings with quantitative data strengthens the overall argument, showing how subjective experience aligns with broader patterns.
This shows the examiner that qualitative evidence is not just quoted but evaluated in terms of credibility and relevance.
Writing with proportionality
Examiners value essays that make proportionate claims.
This means avoiding overstatement (“social media causes eating disorders”) and instead showing balanced reasoning (“social media exposure is associated with increased risk of body dissatisfaction, but effects vary across individuals and contexts”).
Note
Balanced writing demonstrates awareness of limitations and earns higher marks in evaluation.
Checklist for processing evidence into argument
Is each paragraph centred on a theme, not just a single study?
Does every piece of evidenceconnect back to the research question?
Is theory consistently referenced as the framework for interpretation?
Are conflicting findingsacknowledged and explained?
Does the essay use analytical language (supports, challenges, converges, diverges) rather than descriptive language (shows, proves, demonstrates)?
Final reflection on developing argument
Processing evidence is about transforming recorded research into reasoning.
Every paragraph should do more than say what a study found (it should explain what the finding means in the context of your question and theory).
Tip
The examiner should feel, at every stage, that you are building toward a coherent, evidence-based conclusion.
