Alpha oscillations and stimulus-evoked activity dissociate metacognitive reports of attention, visibility, and confidence in a rapid visual detection task (2022)
Journal Article

Variability in the detection and discrimination of weak visual stimuli has been linked to oscillatory neural activity. In particular, the amplitude of activity in the alpha-band (8–12 Hz) has been shown to impact the objective likelihood of stimulus...

Time contracts and temporal precision declines when the mind wanders (2017)
Journal Article

© 2017 American Psychological Association. Our perception of time varies considerably from moment to moment, but how this variability relates to endogenous fluctuations in attentional states has been neglected. Here, we tested the hypothesis that per... Read More about Time contracts and temporal precision declines when the mind wanders.

Students’ perceptions of BIM education in the higher education sector: A UK and US perspective (2017)
Journal Article

© The Author(s) 2017. The use of building information modelling (BIM) has increased in the global architecture, engineering, construction and owner-operated (AECO) industries. This increased use has contributed to a recognition by project stakeholder... Read More about Students’ perceptions of BIM education in the higher education sector: A UK and US perspective.

Attentional sampling of multiple wagon wheels (2013)
Journal Article

Attending to a periodic motion stimulus can induce illusory reversals of the direction of motion. This continuous wagon wheel illusion (c-WWI) has been taken to reflect discrete sampling of motion information by visual attention. An alternative view...

An example motivated discourse of the independent samples t-test and the Welch test
Other

Analyses are given for two example scenarios. Both scenarios comprise two independent samples. One scenario is analysed using the independent samples t-test; the other the Welch test. Commentary on the designs and limitations is given through a qu... Read More about An example motivated discourse of the independent samples t-test and the Welch test.

A primer on validity and design terminology in comparative designs
Other

An overview of terminology (independent and dependent designs, dependent and independent variables) and validity (internal, external, and measurement) is given using six different scenarios. For simplicity of exposition, all examples have factors at... Read More about A primer on validity and design terminology in comparative designs.

An example motivated discourse of the chi-squared test of association (2 by 2)
Other

An example application of the chi-square test of association is given through a set of questions and answers. The emphasis is on methodological aspects and what can be legitimately inferred, if anything. It is strongly highlighted that statistical...

An example motivated discourse of the paired samples t-test
Other

An application of the paired samples t-test is used to discuss the logic underpinning the test and to consider what may be legitimately inferred.

A primer on statistical hypotheses and statistical errors
Other

An abstract overview of some of the logic and statistical considerations in quantitative inference is given

A reverse look at p-values
Other

An overview of p-values is given. The usual way of being introduced to p-values is by considering the rigorous development of statistical tests, then their use for decision making. This note takes a reverse view by firstly considering their use in... Read More about A reverse look at p-values.

That assumption of normality
Other

Many statistical tests are based around an assumption of “normality”. The reasoning for this choice of distribution, whether to test, what to test, and how to test for normality is covered along with practical recommendations.

Cohen’s d for two independent samples
Other

An exposition of standardized effect for two independent samples (under an assumption of normality) is given along with an insight into interpretation and reporting
