Sporer (2008) – Lessons from the Origins of Eyewitness Testimony
Research in Europe
Exam-focused summary (Lecture 1)
1. Core aim of the article
Sporer critically revisits the origins of eyewitness testimony research in Europe (late 19th–
early 20th century) to show that:
• Many “modern” issues in eyewitness psychology were already identified and
studied over 100 years ago.
• Early researchers adopted a broader and more integrated view of testimony than
much contemporary research.
• The field risks historical amnesia by over-crediting later (especially Anglo-
American) contributions.
A key warning is against “presentism” / “Whig history”: the tendency to view history as a
linear progression culminating in today’s science.
2. Who founded eyewitness psychology? (Key historical correction)
Sporer challenges the dominant narrative that Hugo Münsterberg was the founder of
psychology and law.
• Münsterberg (1908) popularised the field in the US (On the Witness Stand), but:
o He cited European work poorly or not at all.
o He overstated claims and antagonised legal professionals.
o His impact was largely popular and institutional, not theoretical.
• L. William Stern (Germany) is presented as the true founder of eyewitness
psychology because he:
o Conducted systematic experimental research.
o Integrated psychology with legal practice.
o Developed methods to measure accuracy, quantity, certainty, and
suggestibility.
o Influenced legal reforms.
• Alfred Binet (France) made major contributions on suggestibility, especially in
children, but did not integrate his work into legal practice as thoroughly as Stern.
Exam takeaway: The origins of eyewitness psychology are European,
interdisciplinary, and methodologically sophisticated, not merely an American invention.
3. Early conceptualisation of eyewitness testimony (VERY IMPORTANT)
Early researchers viewed testimony as: A joint product of cognitive processes and
interrogation context
,This means eyewitness statements are shaped by:
• Perception
• Memory
• Questioning style
• Social influence
• Motivation and intention
This leads to a crucial distinction that remains central today:
Two “enemies of truth”:
1. Error
oUnintentional inaccuracies
oCaused by perception limits, memory decay, suggestion, poor questioning
2. Deception
o Intentional distortions
o Lies, concealment, strategic reporting
o Exists on a continuum, not a yes/no category
Modern research often separates “memory error” and “lying”; early scholars studied them
together.
4. Key early findings that anticipate modern research
Sporer shows that many “modern discoveries” were already known:
• Confidence ≠ accuracy
o Stern’s oath studies showed:
▪ Oaths slightly improve accuracy
▪ But confident statements still contain errors
• Suggestive questioning increases errors
o Especially in children (Binet, Stern)
• Free recall is more accurate than specific questioning
• Repeated questioning can distort memory
• Individual differences in suggestibility matter
• Metamemory (awareness of one’s own memory limits) plays a role
These findings directly anticipate:
• The misinformation effect
• False memory research
• Confidence–accuracy debates
5. Methodological sophistication (often underestimated)
Early researchers developed:
• Quantitative indices for:
, o Accuracy
o Quantity of details
o Subjective certainty
• Experimental paradigms still used today (e.g. staged events, picture paradigms)
• Case-based analyses of real legal files (early statement validity analysis)
Sporer argues that some modern scoring practices are actually cruder than early ones.
6. Strong link with legal reform
Stern and colleagues:
• Advocated lineups instead of show-ups
• Warned against repeated interrogations of children
• Promoted:
o Early interviews
o Neutral questioning
o Trained interviewers
• Influenced real legal procedures (especially in Germany)
Early eyewitness psychology was normative and policy-oriented, not just descriptive.
7. Why this tradition declined
The decline of early eyewitness psychology was not scientific but political:
• Nazi persecution of Jewish scholars (Stern, Lipmann, others)
• Forced migration or death
• Loss of institutional continuity
• Anglo-American dominance rewriting the field’s history
8. Sporer’s integrative model (conceptual anchor)
Sporer proposes an integrative model of eyewitness testimony, distinguishing:
1. Information-processing level
o Encoding → retention → retrieval
2. Metamemory level
o Confidence, certainty, monitoring
3. Judgmental level
o How police, judges, jurors evaluate testimony
Crucial point:
We know much about memory, much less about how fact-finders evaluate memory.
9. Main lessons for contemporary research
• Eyewitness research should:
o Go beyond identification
