Cluster algorithms are gaining in popularity biomedical research due to their compelling ability identify discrete subgroups data, and increasing accessibility mainstream software. While guidelines exist for algorithm selection outcome evaluation, there no firmly established ways of computing a priori statistical power cluster analysis. Here, we estimated classification accuracy common analysis pipelines through simulation. We systematically varied subgroup size, number, separation (effect...
Due to increasing ease of use and ability quickly collect large samples, online behavioural research is currently booming. With this popularity, it important that researchers are aware who participants are, what devices software they access experiments. While somewhat obvious these factors can impact data quality, the magnitude problem remains unclear. To understand how characteristics experiment presentation we performed a battery automated tests on number realistic set-ups. We investigated...
Objective There has been widespread concern that so-called lockdown measures, including social distancing and school closures, could negatively impact children’s mental health. However, there little direct evidence of any association due to the paucity longitudinal studies reporting health before during lockdown. This present study provides first examination changes in childhood health, a key component an urgently needed base can inform policy practice surrounding continuing response...
Eye-tracking technology is becoming increasingly cheaper, both on the hardware and software front. Currently, EyeTribe tracker most inexpensive commercial eye in world, at a price of $99. The low costs make it potentially interesting resource for research, but no objective testing its quality has been performed yet. Here compared with an EyeLink 1000, high-quality video tracker. Results indicate that spatial precision accuracy are good enough fixation checking, point-of-regard analyses,...
Abstract The formation of large-scale brain networks, and their continual refinement, represent crucial developmental processes that can drive individual differences in cognition which are associated with multiple neurodevelopmental conditions. But how does this organization arise, what mechanisms diversity organization? We use generative network modeling to provide a computational framework for understanding diversity. Within macroscopic organization, complete spatial embedding its is an...
Exposure therapy is an efficacious treatment for anxiety-related disorders. Yet, fear often returns after treatment. Occasional reinforcement, in which the feared stimulus intermittently presented during extinction, increases safety learning and slows renewal conditioning paradigms analogue samples, but no studies to date have examined this strategy clinical samples. The present study effects of vicarious occasional reinforcement on a snake-phobic sample across multiple levels analysis. Fear...
Here we show that the pupillary light response reflects exogenous (involuntary) shifts of attention and inhibition return. Participants fixated in center a display was divided into bright dark half. An cue attracted to or side display. Initially, pupil constricted when bright, as compared dark, cued, reflecting shift toward cue. Crucially, this pattern reversed about 1 s after presentation. This later-occurring, relative dilation (when cued) reflected disengagement from previously attended...
Executive function, an umbrella term used to describe the goal-directed regulation of thoughts, actions, and emotions, is important dimension implicated in neurodiversity established malleable predictor multiple adult outcomes. Neurodevelopmental differences have been linked both executive function strengths weaknesses, but evidence for associations between specific profiles neurodevelopmental conditions mixed. In this exploratory study, we adopt unsupervised machine learning approach...
In a cancellation task, participant is required to search for and cross out (“cancel”) targets, which are usually embedded among distractor stimuli. The number of cancelled targets their location can be used diagnose the neglect syndrome after stroke. addition, organization provides potentially useful way measure executive control over multitarget search. Although many measures have been introduced, most fail make into research studies clinical practice due practical difficulty acquiring...

The behavioral and emotional profiles underlying adolescent self-harm, its developmental risk factors, are relatively unknown. We aimed to identify subgroups of young people who self-harm (YPSH) longitudinal factors leading self-harm.Participants were from the Millennium Cohort Study (N = 10,827). A clustering algorithm was used self-harmed with different at age 14 years. then traced back in time (ages 5-14 years) feature selection analyses concurrent correlates self-harming behavior.There 2...
Abstract Psychological research is increasingly moving online, where web-based studies allow for data collection at scale. Behavioural researchers are well supported by existing tools participant recruitment, and building running experiments with decent timing. However, not all techniques portable to the Internet: While eye tracking works in tightly controlled lab conditions, webcam-based suffers from high attrition poorer quality due basic limitations like webcam availability, poor image...
Human-modified environments offer novel resources, but their exploitation can be a source of human-wildlife conflict. Residents Sydney have reported increasing cases bin-opening behavior by sulphur-crested cockatoos (Cacatua galerita), with evidence this is socially learned between birds. Households protected bins, yet to defeat these defences. In response, residents increase defence-level, setting the stage for behavioral "arms race". Here, we investigate arms race combining field...
Saccadic peak velocity increases in a stereotyped manner with the amplitude of eye movements. This relationship, known as main sequence, has classically been considered to be fixed, although several recent studies have demonstrated that can modulated some extent by external incentives. However, ability voluntarily control saccadic and its association motivation yet investigated. Here, three separate experimental paradigms, we measured effects incentivisation on velocity, reaction time...
Abstract Social neurodevelopmental imbalance models posit that peer presence causes heightened adolescent risk-taking particularly during early adolescence. Evolutionary theory suggests these effects would be most pronounced in males. However, the small but growing number of experimental studies on risky decision-making showed mixed findings, and vast majority such did not test for above-described gender phase moderation effects. Moreover, those assess criterion validity employed tasks. The...
A child's socio-economic environment can profoundly affect their development. While existing literature focusses on simplified metrics and pair-wise relations between few variables, we aimed to capture complex interrelationships several relevant domains using a broad assessment of 519 children aged 7-9 years. Our analyses comprised three multivariate techniques that complimented each other, worked at different levels granularity. First, an exploratory factor analysis (principal component...
Disgust helps humans avoid potentially pathogenic substances such as bodily effluvia. This reduces illness risks, and is difficult to overcome with cognitive strategies or even through simple habituation in the short term (minutes hours). Whether emerges long-term (months years) an unsolved question. Regular professional exposure disgust elicitors associated lower sensitivity avoidance, but this could be due selection survivorship bias. Here, we these limitations by testing a sample of...
Understanding the mechanisms underlying complex behaviours--such as reading, decision-making, and human-animal interactions--requires theoretical frameworks that capture real-world complexity while remaining interpretable. While psychological cognitive sciences seem well-positioned to provide such frameworks, they are facing a confidence crisis. A key issue is lack of robust, precise theories capable guiding research. To address this, it has been suggested computational or mathematical...

Abstract Collecting experimental cognitive data with young children usually requires undertaking one-on-one assessments, which can be both expensive and time-consuming. In addition, there is increasing acknowledgement of the importance collecting larger samples for improving statistical power Button et al.
