Effect of Neutral and Negative Images on Galvanic Skin Response: An Activity for Courses in Forensic, Affective, and Behavioral Neuroscience.
Article in Journal of undergraduate neuroscience education : JUNE : a publication of FUN, Faculty for Undergraduate Neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The galvanic skin response (GSR) has provided important scientific insight in a wide range of contexts and has been used in neuroscience research for many decades. It is important for undergraduate students to understand this versatile technique and its application in areas such as Affective, Behavioral, and Forensic Neuroscience. Participants in this study viewed a slideshow containing negative and neutral images selected from the RADIATE and IAPS databases after being connected to a small portable GSR biofeedback monitor. Images were presented for 7-sec on a computer screen followed by a 20-sec blank screen. Each participant's highest GSR response during the 7-sec image presentation was recorded. Participants provided a valence rating, using a 5-point Likert scale, immediately after each image was presented. The mean GSR for images rated as negative was significantly higher than the mean GSR for images rated as neutral. Results were discussed with the class prior to the completion of demographic and activity effectiveness questionnaires. All responses were significant on the activity effectiveness questionnaire. Participants reported a better understanding of the use of GSR in neuroscience, considered this activity a valuable experience, and recommended its use in future classes.
