Intraindividual Variability Matters for the Correspondence Between Subjective Arousal, Valence, and Physiological Responses.
Article in Psychophysiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Affective experiences are inevitably accompanied by physiological changes. However, it is still a matter of intense debate whether events evoking similar affective experiences produce comparable physiological responses (fingerprint hypothesis) or variation is the norm within individuals (populations hypothesis). We reanalyzed data from two independent samples (N = 695; N = 64), using representational similarity analysis (RSA) to examine the trial-by-trial similarity patterns of subjective experience of valence and arousal and affect-related physiological measures (skin conductance [SCR] and startle blink responses) and their modulation by physiological intraindividual variability. Across physiological measures and tasks (passive picture viewing, passive sound listening, and imagery tasks), we observed that disregarding versus considering intraindividual variability when constructing psychophysiological response patterns yielded different associations with affective models, aligning with the fingerprint hypothesis and the populations hypotheses of affect, respectively. More importantly, follow-up analysis revealed that considering intraindividual variability yields a better representation of the SCR and startle patterns across individuals and tasks. Our results demonstrated that similar affective experiences are rather reflected by distinct physiological responses and emphasized the importance of considering intraindividual variability in future studies to better understand how physiological changes contribute to conscious affective experiences in humans.
