Studying eye-gaze has long been employed as a central method for understanding attentional dynamics and cognitive processes in a variety of domains. The development of affordable, mobile eye-tracking devices, such as the Pupil Neon, promises new opportunities to extend this research beyond the contexts in which traditional eye-trackers have been available. But how good are such novel devices at detecting variables relevant for the study of eye movements and pupil dilations?

 

Foucher, Krug and Sauter (2024) propose an independent evaluation of the Pupil Neon eye-tracker using the Ehinger et al. (2019) test battery, comparing its performance with a traditional EyeLink 1000 Plus device. In an empirical study, participants will be asked to perform a wide variety of tasks while eye movements and pupil dilations are tracked using both devices. Results on the strengths and weaknesses, as well as potential use cases of the Pupil Neon will be informative for subsequent eye-tracking research. 

The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the recommender and reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Previous research has demonstrated that experimental participants – both adults and infants – can track syllable co-occurrences in an artificial speech stream. This statistical learning (SL) is thought to support word segmentation and to be a core component of language acquisition. There is also some evidence that SL, as measured through artificial language tasks, is related to individual differences in language learning. What is not well understood is the underpinnings of individual differences in SL. In the current study, van der Wulp et al. (2023) will investigate the relationship between auditory SL and musical – specifically rhythmic – abilities. This work takes advantage of recent methodological innovations which allow online assessment of SL via electroencephalography (EEG) measures of neural entrainment. Up to N=105 participants will be recruited (using a well specified optional stopping procedure) and will be exposed to an artificial language using this EEG method to measure their response to the language through the exposure phase. In addition, post-tests will assess participants’ learning of the artificial language using behavioural tasks, as well as their abilities in a battery of tasks measuring rhythmic, musical, and cognitive abilities, and their vocabulary size. Core analyses will investigate whether the neural signature of statistical learning is found at a group level (i.e. replicating previous work) and whether at the individual level this is related to rhythm perception. Bayes factors will be used to assess the extent of evidence for these hypothesized relationships over the null. Exploratory analyses will explore other relationships, including with working memory and vocabulary size. 

 

The topic of individual differences in language learning and is important, but work in this area is often underpowered, and the correlational nature of the research makes it vulnerable to HARKing. In this context, the current RR looks set to make an important contribution. The Stage 1 manuscript was evaluated over two rounds of in-depth review by the recommender and two expert reviewers, and one additional round of review by the recommender, before issuing in-principle acceptance.

Cerebral small vessel disease (CSVD) is a common and multi-faceted set of pathologies that affect the small arteries, arterioles, venules and capillaries of the brain. The disease manifests through a range of symptoms and conditions, including psychiatric disorders, abnormal gait, and urinary incontinence, while accounting for 25% of strokes and nearly 50% of dementia.

 

The presence of CSVD is associated with white matter lesions (WML) detected using neuroimaging, which have in turn been shown to predict future stroke, cognitive decline and dementia. While vascular risk factors of CSVD (such as hypertension and obesity) are also associated with CSVD, a complete picture of the predictive relationship between WML, cognitive decline, and blood pressure remains to be determined, as does the role of sex/gender. These inter-relationships are important to determine for improving the diagnosis and treatment of CSVD.

 

In the current study, Beyer et al. will analyse a large emerging dataset from the LIFE-Adult project – a longitudinal, two-wave, population-based study – to ask whether higher blood pressure predicts a greater increase in WML, and whether progression of WML is associated with measures of memory and executive function. In addition, the authors will explore the relationship between abdominal obesity and WML progression, and the extent to which WML progression, and its interaction with vascular risk factors, depends on sex/gender.

This study seeks to understand cultural and age differences in the effort moralization effect, a phenomenon in which people who put more effort into a task are considered more moral, regardless of the quality or the morality associated with the task. This is shown in common phrases such as the “great resignation” or “quiet quitting”, which are mostly used against younger members of the population, in particular generation Z.

 

Tissot and Roth (2024) propose to conduct a replication of a study from Celniker et al. (2023) which found evidence for this effect, with new samples from Mexico and Germany to test potential cultural differences. They will also test the effect of age on the effort moralization effect. Therefore, the study will be a quantitative analysis.
 
The authors included an adequate power analysis, alternatives for non-supported hypotheses, and filtering to ensure a high quality of data collection. They already provided an R script and dummy data to ensure the quality of the analysis.

Much of how we use our perception involves judgements on how similar things are: You might vaguely recognise an actor's face in a movie but not immediately recognise where you have seen it before. Some people claim to be "bad with faces". Is that in fact based on objectively poorer ability to recognise faces? Psychophysical lab studies of perception typically use forced-choice discrimination tasks in which participants must make explicit, and usually binary, decisions. Such designs can yield parametric information about underlying perceptual processes, but it is very different from how we use perception in daily life.

 

Here, Moharramipour and colleagues (2024) seek to better understand the link between such subjective similarity jugdements and objective discrimination ability. They argue that subjective similarity can be considered a metacognitive process, reflecting the person's awareness of their perceptual capacity. Participants will be asked to discriminate face pairs across a spectrum of morphing steps in a classical forced-choice paradigm to estimate perceptual threshold performance, as well as provide subjective ratings of similarity of the face pairs. The researchers hypothesise a correlation between objective perceptual ability and subjective similarity judgements. They will evaluate this at the group level, and also use a resampling approach to determine the specificity of this relationship in individual participants. Confirming this hypothesis would advance our knowledge of how perceptual ability links with our metacognitive introspection of it. Are you really "bad with faces" or do you only think you are?
