H567/02 Section A - Understanding disorders: comparing the pair
Freud (1909) and Baron-Cohen et al. (1997) address the same theme through different questions and kinds of evidence. Compare matched features, then judge how far the contemporary study changes understanding and recognition of diversity.
Similarities within understanding disorders
Both studies seek to explain an unusual psychological pattern through a mental process that is not directly visible.
Freud interpreted Hans's phobia through unconscious conflict and displacement. Baron-Cohen et al. inferred advanced theory-of-mind skill from performance on a mental-state task. Both therefore connect observable evidence to a proposed internal process. Neither an interview report nor an Eyes score is direct observation of that process.
Both belong to individual differences: Freud explored an individual child's atypical fear, while Baron-Cohen et al. compared adults with different clinical histories. Both use psychological explanation to make an unusual pattern understandable rather than simply record its existence. Both also use limited samples, so neither alone establishes a universal account. This is a similarity with an evaluative consequence, not a claim that their sample sizes were equal.
A comparison should name the shared feature, provide evidence from both studies and explain why it matters. For example: both infer internal processes; Freud interprets horse fear as displaced anxiety, while Baron-Cohen et al. interpret Eyes performance as mental-state inference; consequently both depend on the validity of that link.
Differences in design, data and validity
The studies offer different kinds of explanation because they collect different kinds of evidence.
| Matched feature | Freud (1909) | Baron-Cohen et al. (1997) | Consequence |
|---|---|---|---|
| Research design | Longitudinal case study of one boy | Quasi-experimental comparison of three adult groups | Freud captures development within a case; Baron-Cohen provides between-group evidence but does not manipulate diagnosis |
| Data | Mainly qualitative accounts sent by Hans's father | Quantitative Eyes scores out of 25 and other task evidence | Freud preserves family meanings; Baron-Cohen supports standard numerical comparisons |
| Measurement | Flexible observations, questioning and symbolic interpretation | Standardised photographs, timing and forced choices | The Eyes procedure is easier to repeat; its narrow stimuli lose ordinary conversational context |
| Researcher's relation to evidence | Father and Freud favoured the explanatory theory | Comparison groups and control tasks tested alternative explanations | Freud is vulnerable to leading questions and confirmation bias; Baron-Cohen reduces some alternatives but cannot remove all background differences |
Neither method is automatically best for every question. A 25-item score would not capture Hans's changing family experiences; one child's life history would not establish a mean difference between adult clinical groups. Comparing methods should connect each method's strength or weakness to the question it can answer.
Ethical issues also differ. Intimate questioning of a five-year-old by his parent raises assent, distress and privacy concerns. Brief adult tasks reduce some of those risks, but clinical labels and group comparisons can produce embarrassment or social stigma. Do not infer that either study documented all modern safeguards merely because its aim was helpful.
