Mapping 60 Years of Psychophysiology: A Bibliometric Analysis of Journal Performance, Authorship Trends, and Thematic Evolution
No full textPsychophysiology, the flagship journal of psychophysiological research, has played a key role in the field for 60 years. For the present study, we conducted a bibliometric analysis assessing the journal's development in terms of performance, authorship trends, and thematic content for this time span. Over the years, Psychophysiology has experienced a consistent increase in manuscript submissions, published articles, and impact factor. Authorship trends showed larger, more diverse author teams, with a growing percentage of female first authors now representing about 50% of submissions and an increase in international collaborations. Thematic content has evolved, shifting from peripheral measures to central nervous system measures like EEG and ERPs while maintaining the journal's long-standing emphasis on methodological advancements. Research topics have expanded from basic stimulus processing to more complex investigations into emotion, cognition, and psychopathology, with growing interdisciplinary integration. This article provides a quantitative overview of Psychophysiology's contributions and development, aimed at offering insights into the journal's past, current state, and potential future directions in psychophysiological research

Imagery-based threat conditioning in children
No full textChildhood can be a sensitive phase for the development of stable fears or even phobias (E. C. King et al., 2014; N. J. King et al., 1991). Affected children experience this fear not only in the face of actual danger (e.g., encountering a dog) but also in response to cues that signal this danger (e.g., fear-associated places like parks). The processes underlying this development are only partially understood.
Mechanisms of classical conditioning are assumed to play a major role in the acquisition and maintenance of fear but have not been successful in explaining fears in the absence of real-life aversive experiences (Dadds et al., 1997; D. L. King, 1973; Mertens et al., 2020). In addition to observational and instructed learning, mental imagery can contribute to the development and maintenance of fears and defensive responses via associative learning mechanisms (Mertens et al., 2020 for a review). In a specific line of research, we could show that repeatedly pairing a visual conditioned stimuli (CS) with mere mental imagery of an aversive event (e.g., receiving an electric shock, stepping on a thumbtack) will induce subjective and electrophysiological conditioned fear responses to the CS in adults (Mueller et al., 2019; Panitz & Mueller, 2024).
While imagery has repeatedly been shown to contribute to fear via associative learning in adults, there is no comparable research in children. Given that fears acquired in childhood may become persistent (E. C. King et al., 2014; N. J. King et al., 1991), knowledge about the underlying mechanisms is key to develop better preventive and therapeutic strategies. This study aims to investigate – using EEG, ECG and rating data – to what extent repeated mental imagery of aversive events can contribute (a) to elevated threat appraisal of these events in children and (b) to conditioned responses to CS that predict these events.
To this end, children aged 7 to 10 years will be shown pictures of three fictional animals on a screen. In the beginning, children will receive background information that describes the different animals as harmless (e.g., "eats leaves and berries," "squeaks gently") or threatening ("eats raw meat," "growls loudly"; cf. Field & Lawson, 2003). Subsequently, children are instructed for the rest of the experiment to always imagine encountering the animal that is presented on the screen. Instructions are delivered via standardized audio scripts and instruct children to either always imagine a harmless encounter with a given animal (the animal looks interested and squeaks, the child has a steady heartbeat and feels relaxed) or always a threatening encounter (the animal looks threatening and growls, the child has an accelerated heart beat and is afraid). In a subsequent conditioning phase, the animals are preceded by pictures of landscapes that the animals supposedly live in (desert, forest, mountains). Here, landscapes are used as conditioned stimuli and are effectively paired with aversive or non-aversive imagery as unconditioned stimulus (US).
Children will rate the animals on valence and arousal scales after delivery of background information and after the conditioning phase. Landscapes are rated on the same scales after the conditioning phase. Additionally, during the conditioning phase, ECG and EEG will be recorded to assess the unconditioned physiological response to imagery (interbeat interval via ECG; cf. Lee et al., 1996) and the central processing of CS measured with EEG (Late Positive Potential [LPP], cf. Panitz & Mueller, 2024; posterior alpha suppression, cf. Panitz et al., 2019). The LPP is an established marker of motivational significance, selective attention, and sustained emotional engagement in response to visual stimuli (Gupta et al., 2019; Wieser & Keil, 2020). Posterior alpha suppression can be found in response to visual stimulus processing and is enhanced in selective attention, reflecting enhanced gain in early visuocortical brain regions (Foxe & Snyder, 2011; Klimesch, 2012).
In a brief interview following the conditioning phase, children will be asked whether they (a) recall the landscape-animal contingencies correctly and (b) were able to produce the correct imagery for each animal (see Measured Variables section for more details). While children perform the computer task, parents fill out a self-translated version of the short form of the revised Fear Survey Schedule for Children (FSSC-R-SF; Muris et al., 2014) to assess children’s overall fearfulness.
Taken together, this study investigates how mental imagery processes contribute to:
(a) the appraisal of potential threats (ratings to animals),
(b) the association of previously neutral CS with threat imagery, as CS become threat cues (ratings on landscapes), and
(c) whether neural conditioned responses indicate elevated motivational significance and selective attention to threats and threat CS (LPP to animals, LPP & alpha suppression to landscapes).
Findings from this study will provide insights into whether repeated mental imagery is a mechanism by which children evaluate potential threat cues in their environment more negatively and whether these cues are prioritized on the neural processing level, despite the absence of real-life aversive experiences. The planned study aims to contribute to a better understanding of the neuropsychological mechanisms that contribute to the development of stable fears – and thus can also be used prevent the development of such fears
Aversive imagery causes de novo fear conditioning (Open Data and Open Materials)

In classical fear conditioning, neutral conditioned stimuli (CS) that have been paired with aversive physical unconditioned stimuli eventually trigger fear responses. Here, we test whether aversive mental images systematically paired with a CS may also cause de novo fear learning in the absence of any external aversive stimulation. In two experiments, N=45 and N=41 participants were first trained to produce aversive, neutral, or no imagery in response to one of three different visual imagery cues. In a subsequent imagery-based differential conditioning paradigm, each of the three cues systematically co-terminated with one of three different neutral faces. Although the face that was paired with the aversive imagery cue was never paired with aversive external stimuli or threat-related instructions, participants rated it as more arousing, unpleasant, and threatening and displayed relative fear bradycardia and fear-potentiated startle. These results could be relevant for the development of fear and related disorders without trauma.Open Data and Open Materials of:
