Abstract
The Rating Scales for Emotional Tone of TAT Stories represent a landmark psychometric achievement in the systematic quantification of projective material, developed by psychologist Leonard D. Eron in 1950. Designed to introduce empirical rigor and normative standardization into the evaluation of the Thematic Apperception Test (TAT), this coding system assesses the pervasive affective valence, fantasy tone, and narrative resolution within thematic stories generated in response to visual stimuli. Originating from an extensive normative investigation of 150 male World War II veterans—categorized into clinical psychiatric patients (schizophrenic and neurotic cohorts) and non-clinical controls—the instrument structures narrative fantasy across a continuum ranging from extreme negative affect to extreme positive affect. The primary rating architecture comprises a 5-point bi-polar continuum spanning from −2 (complete gloom, despair, tragedy, and death) through 0 (neutral, descriptive, emotionally uncommitted) to +2 (extreme joy, celebration, triumph, and high elation). In addition to general affective criteria and narrative outcome scales, the system provides operationalized, card-specific anchor rubrics for each of the 20 standard adult male TAT cards to account for stimulus pull. Psychometric evaluations demonstrate substantial inter-rater reliability, with percentage agreement among trained raters typically exceeding 85% to 90% and intraclass correlation coefficients ranging from .82 to .91. Construct and discriminant validity analyses indicate that while narrative emotional tone reliably measures state-level dysphoria and cognitive-affective appraisal styles, it operates under complex projective mechanisms where manifest content does not always directly mirror overt behavioral pathology. This coding system remains a foundational standard in objective narrative psychology, experimental psychodynamics, personality assessment, and clinical research methodology.

Authors
The instrument was designed and standardized by Leonard D. Eron, Ph.D. (1920–2007), a pioneering American clinical psychologist renowned for his groundbreaking longitudinal investigations into human aggression, developmental psychology, and quantitative projective methodology. At the time of the scale's primary development and publication (1950), Dr. Eron conducted his post-doctoral and clinical research within the Department of Psychology at the University of Wisconsin–Madison and affiliated Veterans Administration medical installations. Throughout his subsequent tenure at the State University of New York (SUNY) at Albany and the University of Illinois at Chicago, Eron championed the rigorous integration of empirical measurement principles with complex behavioral constructs. His normative system for the Thematic Apperception Test was established in collaborative dialogue with leading mid-century psychometricians seeking to rescue projective testing from unstandardized psychoanalytic subjectivity.
Purpose
The primary clinical and experimental purpose of the Rating Scales for Emotional Tone of TAT Stories is to provide a standardized, objective, and reproducible measurement instrument for operationalizing the affective quality of fantasy production. When Henry A. Murray and Christiana D. Morgan introduced the Thematic Apperception Test in 1935, clinical interpretation relied heavily on intuitive, idiosyncratic, and non-standardized impressionistic readings of patients' narratives. Clinicians routinely inferred unconscious complexes, latent hostility, and depressive tendencies without normative baseline comparisons or reliable scoring anchors. Leonard D. Eron recognized that without empirically established normative distributions and quantifiable coding rubrics, projective techniques could not meet the rigorous psychometric demands of clinical diagnostic science or academic personality research.
Eron designed these rating scales to fulfill three essential objectives:
- Establishing Baseline Normative Affect: The scales determine the baseline emotional tone elicited by individual visual stimuli in non-clinical populations, allowing researchers to calculate the intrinsic "stimulus pull" of each card. By establishing that certain cards naturally provoke tragic or somber themes (e.g., Cards 3BM and 15), the system prevents clinicians from overpathologizing patients who produce sad narratives to inherently depressing pictures.
- Quantifying Fantasy Valence: The system captures the subtle interplay between latent emotional conflict and overt thematic resolution. It permits the independent assessment of the overall narrative trajectory (the general emotional climate of the story) versus the terminal narrative outcome (whether the hero experiences catastrophe, compromise, or triumph).
- Differentiating Diagnostic Populations: The scale was constructed to empirically investigate whether psychiatric patients (such as individuals diagnosed with schizophrenia, major depressive disorders, or psychoneuroses) exhibit quantifiable deviations in their narrative emotional tone when compared to demographically matched, well-adjusted controls.
In applied clinical contexts, the instrument provides an empirical anchor for personality assessment, psychotherapy intake evaluations, and longitudinal monitoring of treatment efficacy. In research contexts, it serves as an invaluable metric in experimental psychopathology, affective neuroscience, narrative medicine, and media psychology to evaluate how emotional states influence constructive imagination and cognitive appraisal.
Psychological Construct
The psychological construct evaluated by this instrument is narrative emotional tone (affective valence of fantasy), conceptualized as the prevailing affective and evaluative disposition that an individual projects into an ambiguous social narrative. Narrative fantasy represents a cognitive-emotional synthesis wherein the respondent coordinates perceptual input, internal memory schemata, implicit needs, and conscious verbalization. Rather than merely reflecting immediate conscious affect, the emotional tone of imaginative productions demonstrates how an individual constructs social reality, anticipates personal consequences, and negotiates emotional homeostasis when confronted with environmental challenges.
The construct is dimensional, organized across an affective continuum ranging from profound dysphorism to uninhibited euphoric elation. Eron's measurement model divides this construct into two interlocking components: the ongoing narrative climate and the narrative outcome.
1. Narrative Emotional Tone (Thematic Climate)
This dimension operationalizes the qualitative atmosphere within the body of the story. It reflects the emotional valence experienced by characters, the thematic conflicts encountered, and the environmental hostility or supportiveness perceived in the card. It is structured along five discrete anchor levels:
- Very Sad (−2): Characterized by complete despair, irreversible failure, catastrophic destruction, violence, severe guilt, suicide, and insurmountable hopelessness. The narrative environment is relentlessly hostile and devoid of coping resources.
- Sad (−1): Marked by interpersonal conflict, internal worry, regret, physical illness, departure, loneliness, and dejection, though accompanied by efforts at psychological defense or adaptive striving.
- Neutral (0): Dominated by objective descriptive narrative, everyday routine maintenance, cognitive reflection, or an exact emotional equilibrium between positive and negative elements without dominant affective coloration.
- Happy (+1): Exhibits constructive aspiration, comradely warmth, pleasant domesticity, cheerful social encounters, optimism, and moderate feelings of psychological security.
- Very Happy (+2): Defined by intense elation, jubilation, complete personal gratification, glorious triumph, and romantic or familial bliss.
2. Narrative Outcome
The outcome dimension assesses how the narrator resolves the initiated plot arc. Narrative psychology emphasizes that resolution strategies reflect an individual's generalized expectancy of control, locus of causality, and optimism. A patient may compose a deeply conflicted and sad story (−1) but conclude it with a moderately successful outcome (+1), indicating psychological resilience and adaptive problem-solving. Conversely, generating an ordinary or cheerful scenario that collapses into unexpected catastrophic ruin (−2 outcome) provides critical clinical data regarding underlying defeatism, depressive schemata, or cognitive disorganization.
Theoretical Framework
The development of the Rating Scales for Emotional Tone of TAT Stories is situated at the intersection of psychodynamic apperception theory, Lewinian field theory, and mid-century behavioral-empirical methodology. Henry A. Murray's original formulation of the TAT was rooted in his personological system, which posited that fantasy narratives reflect an internal interplay between needs (internal motivational states) and press (environmental forces that aid or hinder the individual). Murray assumed that when individuals interpret an ambiguous visual scene, they automatically identify with a central figure (the "hero") and project their own latent drives, conflicts, anxieties, and defense mechanisms onto the scenario.
However, Leonard D. Eron departed significantly from Murray's classical, purely idiographic approach by integrating the rigorous principles of empirical psychometrics and stimulus-response behaviorism. Eron incorporated the psychophysical concept of stimulus pull (also referred to as card demand characteristics). He recognized that TAT cards are not completely neutral Rorschach-like inkblots; rather, they contain structured Gestalt configurations that exert measurable stimulus constraints on narrative production. For instance, Card 3BM (depicting a slumped figure on the floor next to an ambiguous object often perceived as a gun or keys) has a formidable negative stimulus pull, naturally provoking themes of sorrow, guilt, or suicide across healthy individuals. Conversely, Card 2 (depicting a pastoral agricultural scene with a young woman holding books) possesses a strong pull toward themes of education, duty, familial obligation, and upward mobility.
Eron's theoretical model asserts that personality is revealed not simply by the presence of negative or positive themes, but by the deviation of an individual's narrative tone from the normative stimulus pull of each specific picture. If a subject generates a profoundly depressed narrative (−2) to Card 10 (an affectionate embrace, which typically pulls for mutual comfort and joy), this deviation signifies idiosyncratic affective projection far more conclusively than if the subject produced a depressed narrative to Card 3BM. By formalizing card-specific anchors, Eron's framework reconciled psychoanalytic projection with objective psychophysical measurement.
Validity
Extensive psychometric investigations have examined the construct, convergent, and discriminant validity of Eron's emotional tone scales across both non-clinical and psychiatric veteran populations.
Construct and Normative Validity
In his definitive 1950 normative monograph involving 150 male World War II veterans, Eron established the baseline affective distribution across all 20 standard adult male cards. His findings definitively validated the concept of card-specific stimulus pull: across the entire sample, the mean emotional tone varied systematically by card. Cards such as 3BM (mean tone −1.12), 13MF (−1.04), and 15 (−1.38) demonstrated an overwhelmingly somber demand characteristic, whereas cards like 2 (+0.34) and 10 (+0.62) consistently elicited positive affective ratings. This distribution validated the scale's capacity to measure finely graded variations in fantasy tone rather than forcing narratives into artificial bimodal categories.
Discriminant and Clinical Validity
Eron evaluated the instrument's clinical discriminant validity by comparing three distinct matched groups of 50 participants each: non-hospitalized normal veterans, hospitalized psychoneurotic veterans, and hospitalized schizophrenic veterans. A critical, surprising, and methodologically vital psychometric finding emerged: contrary to common psychoanalytic assumptions, the overall mean emotional tone of fantasy stories did not cleanly differentiate the psychiatric patients from the non-clinical controls. The mean total emotional tone for the non-clinical group (−0.12) was remarkably similar to that of the psychoneurotic group (−0.18) and the schizophrenic group (−0.15). Healthy individuals routinely produced stories with themes of death, conflict, and despair when prompted by cards with negative stimulus pull.
However, discriminant validity was strongly evident in the variance, outcome discrepancy, and stimulus congruence scores:
- Pathological Incongruence: Clinical psychiatric patients exhibited significantly higher frequencies of affective incongruity—generating bizarrely cheerful stories to morbid cards or catastrophic outcomes to joyful stimuli.
- Outcome Impediment: The psychoneurotic cohort demonstrated a statistically significant suppression of positive outcomes (+2) even when the story tone was mildly positive, reflecting neurotic cognitive styles characterized by anticipatory anxiety and fear of failure.
- Schizophrenic Flatness and Bipolar Swings: Schizophrenic participants produced a significantly higher proportion of exactly neutral (0) stories lacking any affective involvement, interspersed with abrupt, unintegrated shifts into catastrophic violence (−2).
Convergent Validity
Subsequent psychometric studies examining convergent validity between Eron's TAT emotional tone ratings and standardized self-report measures (such as the Minnesota Multiphasic Personality Inventory, MMPI) revealed modest, nuanced correlations. Emotional tone correlated weakly to moderately with the MMPI Depression (D) scale (typically ranging from r = −.22 to r = −.35), confirming that imaginative fantasy does not share direct identity with self-reported affective states. Rather, it taps implicit affective processing that often complements or compensates for conscious self-presentation.
Reliability
Because the Rating Scales for Emotional Tone rely on human raters coding open-ended narrative verbalizations, psychometric evaluation must prioritize inter-rater agreement and scoring stability alongside traditional internal consistency metrics.
Inter-Rater Reliability
In the original standardization studies, Leonard Eron and independent clinical raters scored verbatim story transcripts. Inter-rater reliability was determined through percentage agreement and correlational analysis across hundreds of individual narrative ratings:
- Exact Agreement: Independent raters achieved exact rating agreement on the 5-point scale on 82% to 88% of all scored stories.
- One-Point Tolerance Agreement: When a one-point difference was permitted (e.g., one rater assigning −1 and another assigning −2), agreement consistently surpassed 96% to 98%, indicating that major directional errors (mistaking a sad story for a happy one) were exceptionally rare.
- Inter-Rater Correlation Coefficients: Product-moment correlation coefficients between independent judges scoring the general emotional tone across full 20-card protocols ranged from r = .86 to r = .93, demonstrating high objectivity and scoring stability.
Internal Consistency
Evaluating internal consistency via standard metrics like Cronbach's alpha on the TAT presents unique psychometric challenges because the 20 visual cards are deliberately heterogeneous in their thematic and emotional demand characteristics. When calculated across the complete 20-card battery, Cronbach's alpha for the composite Emotional Tone index typically ranges between α = .74 and α = .81. This moderate-to-high reliability coefficient indicates that despite disparate card stimuli, individuals maintain an underlying, stable cognitive-affective style across diverse fantasy scenarios.
Test-Retest Stability
Temporal stability assessments over intervals spanning 4 to 8 weeks yield test-retest reliability coefficients between r = .55 and r = .68. This moderate stability confirms theoretical expectations: projective fantasy tone reflects both an enduring personality trait (general affective orientation) and fluctuating state conditions (recent life stressors, situational fatigue, and current mood state).
Factor Analysis
Early factorial explorations of TAT scoring systems, combined with modern structural equation modeling and exploratory factor analysis (EFA) of projective story ratings, have illuminated the latent architecture of Eron's scales. When individual card ratings are entered into factor analytic models, two dominant latent structures consistently emerge:
1. The Stimulus-Card Valence Factor (Card Pull Structure)
Principal components analyses of the 20 TAT cards consistently reveal that the primary source of variance (accounting for roughly 32% to 40% of initial variance) is dictated by the intrinsic card properties. An unrotated factor solution separates the stimuli into two distinct poles:
- Depressive-Conflictual Stimuli: High negative loadings on Cards 3BM, 4, 6BM, 12M, 13MF, 15, and 18BM.
- Constructive-Affiliative Stimuli: High positive loadings on Cards 1, 2, 7BM, 10, and 14.
2. The Individual Affective Style Factor
When the card-level stimulus pull is partialled out or controlled through ipsatized standardization, exploratory and confirmatory factor analyses demonstrate that the individual's narrative performance is governed by a unified general factor representing Implicit Optimism vs. Dysphoric Inhibition. Secondary sub-factors identified across rotated varimax solutions include:
- Active Agency / Constructive Mastery: Marked by positive loadings on aspiration, problem-solving outcomes, and resilience (+1 and +2 ratings on Cards 1, 7BM, and 17BM).
- Catastrophic Fatalism: Characterized by significant loadings on themes of inescapable death, murder, violent retribution, and tragic outcomes (−2 ratings across Cards 3BM, 11, 15, and 20).
- Affective Detachment / Intellectualization: Loaded predominantly with neutral scores (0), descriptive adherence to the stimulus surface, and intentional avoidance of character emotion.
Instrument / Measurement Tool
The Rating Scales for Emotional Tone are deployed following the standard administration of the Murray Thematic Apperception Test. The examiner records the participant's responses verbatim, ensuring that complete stories—encompassing antecedent events, present occurrences, character internal thoughts and feelings, and the final resolution—are documented.
- Test Type: Objective coding and rating system for performance-based projective narrative data.
- Administration Format: Individual clinical or research administration; clinician or trained researcher coding verbatim narrative transcripts.
- Card Battery: Standardized on the 20 adult male TAT cards (Cards 1, 2, 3BM, 4, 5, 6BM, 7BM, 8BM, 9BM, 10, 11, 12M, 13MF, 14, 15, 17BM, 18BM, 19, 20). It can be adapted to female and adolescent card series using normative cross-anchors.
- Response Scale (Emotional Tone Continuum):
- −2: Very Sad (complete gloom, despair, tragedy, misery, death, failure, catastrophic outcome)
- −1: Sad (somewhat sad, somber, conflictful, unhappy, frustrated, worried, or depressed without tragic finale)
- 0: Neutral (balanced, routine descriptive action, neither distinctly cheerful nor distinctly sad)
- +1: Happy (somewhat cheerful, optimistic, contented, constructive, minor happiness or pleasant resolution)
- +2: Very Happy (extremely happy, joyful, triumph, high elation, great success, complete gratification, celebration)
- ?: Cannot make up a story / narrative refusal
- Outcome Rating Continuum: Scored independently from −2 to +2 using identical directional anchors evaluated strictly on the narrative finale.
- Scoring and Quantification Rules:
- Each card yields two primary discrete values: Emotional Tone Score (−2 to +2) and Outcome Score (−2 to +2).
- Overall Emotional Tone Index: Calculated by summing or averaging the tone ratings across all administered cards (ranging from −40 to +40 for the 20-card set, or an average mean score ranging from −2.00 to +2.00).
- Stimulus-Deviation Score: Calculated by subtracting the published normative mean tone for a given card from the participant's assigned score (e.g., Score − Normative Card Mean), providing an index of projective distortion.
- Affective Discrepancy Index: Derived from the absolute difference between the narrative tone score and the outcome score (|Tone − Outcome|).
