The Psychological Research Preregistration-Quantitative Template has been created in 2022 to provide more structure and detail to preregistrations. The goal of the current study is to test if the PRP-QUANT template indeed provides greater restriction of the flexibility in a study for preregistered hypotheses than other existing templates. This question is important because one concern that has been raised about the practice of preregistration is that the quality of preregistrations is often low. Metascientific research has shown that preregistrations are often of low quality (Bakker et al., 2020), and hypothesis tests from preregistrations are still selectively reported (van den Akker, van Assen, Enting, et al., 2023). It is important to improve the quality of preregistrations, and if a better template can help, it is a cost-effective approach to improve quality if the wider adoption of the better template can be promoted. 

 

In the current study, Spitzer and Mueller (2024) will follow the procedure of a previous meta-scientific study by Heirene et al. (2021). 74 existing preregistrations with the PRP-QUANT template are available, and will be compared with an existing dataset coded by Bakker and colleagues (2020). The sample size is limited, but allows detecting some differences that would be considered large enough to matter, even though there might be smaller differences that would not be detectable based on the currently available sample size. Nevertheless, given that there is a need for improvement, even preliminary data might already be useful to provide tentative recommendations. Restrictiveness will be coded in 23 items, and adherence to or deviations from the preregistration are coded as well. As such deviations are common, the question whether this template reduced the likelihood of deviations is important. Two coders will code all studies. 

 

The study should provide a useful initial evaluation of the PRP-QUANT template, and has the potential to have practical implications if the PRP-QUANT template shows clear benefits. Both authors have declared COI's related to the PRP-QUANT template, making the Registered Report format a fitting approach to prevent confirmation bias from influencing the reported results.

In a previous analysis of data from 988 participants in the Hamburg City Health Study (HCHS), Schlemm and colleagues (2022) reported significant associations between the extent of cerebral small vessel disease (cSVD) and dynamic functional connectivity measures from resting state fMRI. Specifically, the volume of white matter hyperintensities of presumed vascular origin, a structural indicator of cSVD, was negatively related to the proportion of time (‘fractional occupancy’) spent in the two most occupied functional brain states. Reduced fractional occupancy was also associated with longer times to complete part B of the Trail Making Test.

 

In the present Registered Report, Ingwersen and colleagues (2023) successfully replicated these associations between structural, functional and cognitive measures in a sample of 1651 HCHS participants not included in the earlier study. An exploratory multiverse analysis found that the associations were generally robust to different brain parcellation and confound regression strategies. These replicable patterns reinforce the idea that cSVD may disrupt the brain’s ability to enter and maintain distinct functional modes, and that these changes in functional dynamics are predictive of cognitive impairment.

When receiving a favour, we may feel grateful and/or indebted to those who have helped us. What factors determine how much gratitude and indebtedness people experience? In a seminal paper, Tsang (2006) found that people reported feeling more gratitude when the helper's intention was benevolent (e.g., helping others out of genuine concerns for other people) compared to when the helper's intention was perceived to be selfish (e.g., helping others for selfish reasons). In contrast, indebtedness was not influenced by perceived helper intention. This finding highlighted the different processes underlying gratitude and indebtedness, and also inspired later work on how these two emotions may have different downstream influences, for instance on interpersonal relationships.

So far, there has been no published direct replication of this seminal work by Tsang (2006). In the current study, Chan et al. (2024) propose to revisit the effects of helper intention on gratitude and indebtedness, by replicating and extending the original studies (Study 2 & 3) by Tsang (2006). Participants will be asked to either recall (Study 2) or read (Study 3) a scenario in which another person helped them with either benevolent or selfish intentions, and rate how much gratitude and indebtedness they would experience in such situations. The authors predict that in line with the original findings, gratitude will be more influenced by helper intention than indebtedness. To further extend the original findings, the authors will also assess people's perceived expectations for reciprocity, and their intention to reciprocate. These extensions will shed further light on how helper intention may influence beneficiaries’ experiences of gratitude and indebtedness, and their subsequent tendencies to reciprocate.

What are the neurophysiological correlates of paired associative stimulation (PAS) in inducing plastic changes in human motor cortex (M1)? Here, Arrigoni and colleagues (2024) will apply transcranial magnetic stimulation (TMS) to left M1 paired with electrical stimulation of the right median nerve at an ISI of 25 ms or 10 ms to induce long-term potentiation (LTP) or long-term depression (LTD), respectively. Arrigoni and colleagues (2024) will determine if these stimulation pairings effect cortical excitability using motor-evoked potentials (MEPs) and TMS-evoked potentials (TEPs). Specifically, they hypothesize PASLTP will increase the peak-to-peak amplitude of MEPs, whereas PASLTD will decrease the amplitude, replicating previous work. They will then extend these previous findings by examining TEPs. The authors anticipate modulation of the P30 and P60, which are TEPs thought to reflect local cortical excitability. They plan to account for the MEP reafference which may also mediate the P60 amplitude by stimulating at sub- and supra- motor threshold. Further, they hypothesize an increase of the N100, a marker of inhibitory processing mediated by GABA, by PASLTD. Finally, the authors will also examine the impact of cortical excitability over time to determine the duration of the PAS effects.   

 

This detailed examination of TEPs following PAS stimulation will determine which TEPs could be used as biomarkers with the induction of LTP and LTD through stimulation. The authors have built in an MEP replication for the PAS stimulation, supporting previous literature and acting as a positive control.

Are attention and consciousness inherently intertwined or distinct aspects of cognition? One report (Jiang et al. 2006) presented clear results in evidence of the latter. In this earlier study, the authors used a continuous flash suppression (CFS) paradigm which presents a colorful pattern to the dominant eye and stimuli of interest to the non-dominant eye; the colorful pattern masks the relevant stimulus from awareness. On each trial, the authors presented a sexually stimulating image and a scrambled image on different sides of a computer screen during CFS. They found that, even though participants were not consciously aware of the images, intact images that matched participants' sexual orientation could still capture attention.

 

Despite these seemingly clear results, the authors of the current Stage 1 manuscript pointed out that CFS studies are often not replicated, and the paper by Jiang et al. (2006) is no exception. Therefore, Chen et al. (2023) seek to replicate this study using a Bayesian (rather than NHST) analytic approach. This method will allow the authors to determine the strength of evidence for their hypotheses.

 

In this Stage 1 manuscript, Chen et al. present an introduction that motivates the replication, and a pilot study that replicated the procedure of Jiang et al. (2006) conducted with 21 participants. This led to a well-motivated statistical sampling plan and some small design changes for the main experiment, such as adding a staircasing procedure to remove potential performance ceiling effects, and using less extreme wording for stimulus attractiveness ratings. A clear study design template is presented, detailing the different hypotheses that will be tested, and what different outcomes would indicate.
