Disentangling eye movement desensitization and reprocessing mechanisms of action: The impact of eye movements in the eye blink conditioning task.
Trial report in Psychology and psychotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesEye movement desensitization and reprocessing (EMDR) is an effective evidence-based treatment for post-traumatic stress disorder. However, the therapeutic mechanisms underlying eye movements (EM) remain unclear. This study aimed to investigate the effect of horizontal EM on fear extinction learning in healthy individuals, using an Eye Blink Conditioning (EBC) task. This experimental paradigm has been widely used to explore associative fear learning and memory as a form of classical conditioning.
methodsHealthy participants were included to the study protocol and divided randomly into two groups. The EM group (n = 20) were asked to follow horizontally the experimenter's moving finger at the beginning of the extinction phase and the control group (n = 19) did not engage in any specific task. Sociodemographic and clinical information was collected. Percentage of conditioned response (CR) occurrence, time of onset and intensity between and within groups over longitudinal time were analysed using generalized multilevel mixed effects for repeated measures.
resultsResults showed accelerated extinction learning in the EM group, with an 18.2% probability of CR occurrence in the first block of extinction, compared to the control group (40.9%) (p-value = .007).
conclusionsThe findings indicate that horizontal EM accelerates the extinction process in the EBC task. Therefore, this paradigm, used for studying associative learning and memory, could serve as an objective measure to investigate the mechanisms of action involved in desensitizing traumatic experiences during EMDR treatment.
