Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Using cannabis may moderately impair visuospatial processing and learning in nondependent high school students. → Goycolea 2020

Evidence¶

Goycolea 2020¶

Goycolea, Rodrigo; Castro Alonso, Juan; Dörr Álamos, Anneliese. (2020). Visuospatial Processing Decline Due to Cannabis Consumption in Nondependent High School Students. Educational Psychology Review. https://doi.org/10.1007/s10648-020-09564-8

q2 · i? · review · r?

The review's synthesis of experimental and correlational evidence on cannabis use in nondependent high school students concludes that use "may moderately impair visuospatial processing and learning" in this population. The review reports this as a moderate impairment, hedged with "may".

"We conclude that using cannabis may moderately impair visuospatial processing and learning in nondependent high school students, although the effects could disappear under abstinence"

Discussion¶

Learner Variables¶

Spatial Ability — outcome: instruction changes it

Detrimental effects of cannabis on cognitive, academic, and professional performance tend to be larger in younger users — a broader claim this one bears on
Visuospatial processing effects of cannabis could disappear under abstinence in nondependent high school students — related
Cannabis effects on visuospatial processing tend to be lower than on other cognitive functions — related
Visuospatial processing plays a pivotal role for learning — related
