Reimagining André Rey's method for recording the copy process of the Rey Complex Figure Test: A commentary.
J Neuropsychol
January 2025
Department of Aged Care and Rehabilitation, Liverpool Hospital, Sydney, New South Wales, Australia.
In 1941, André Rey published the Rey Complex Figure, a widely used test for assessing visual-constructional ability and visual memory. It consists of two parts: copy and recall. Evaluating the copy portion presents challenges, as it requires the administrator to focus on both the process and outcome.

Background: In 1962, the idea emerged that medical students' tolerance of uncertainty could determine their specialty choice. While some studies supported this claim, others refuted it, often using independently developed instruments. We explored whether the reported link between specialty choice and uncertainty tolerance is more myth than evidence by employing established instruments to investigate whether specialty choice could be explained by variance in uncertainty tolerance.

Using genetic data to infer evolutionary distances between molecular sequence pairs based on a Markov substitution model is a common procedure in phylogenetics, in particular for selecting a good starting tree to improve upon. Many evolutionary patterns can be accurately modelled using substitution models that are available in closed form, including the popular general time reversible model (GTR) for DNA data. For more complex biological phenomena, such as variations in lineage-specific evolutionary rates over time (heterotachy), other approaches such as the GTR with rate variation (GTR ) are required, but do not admit analytical solutions and do not automatically allow for likelihood calculations crucial for Bayesian analysis.

Transcranial magnetic stimulation (TMS) has been used for many years to study the pathophysiology of amyotrophic lateral sclerosis (ALS). Based on single- or dual-pulse TMS and EMG and/or single motor unit (MU) recordings, many groups have described a loss of central inhibition as an early marker of ALS dysfunction, reflecting a state of cortical 'hyperexcitability'. This conclusion is not without its detractors, however, leading us to reexamine this issue using 4-pulse TMS, shown previously to be more effective for testing central motor pathway functional integrity.
