Since almost a hundred years, psychologists have investigated the link between hand preference and dyslexia. We present a meta-analysis to determine whether there is indeed an increase in atypical hand preference in dyslexia. We included studies used in two previous meta-analyses (Bishop, 1990; Eglinton & Annett, 1994) as well as studies identified through PubMed MEDLINE, PsycInfo, Google Scholar, and Web of Science up to August 2022.

For depression, however, this relationship is largely unclear. While a few studies found evidence that handedness and depression are associated, both the effect size and the direction of this association remain elusive.

- Cue competition is the idea that learning about one cue's relationship to an outcome is affected by other cues that are present at the same time.
- In experiments with pigeons, researchers tested this by using different training methods to see how cues compete for predictive value.
- Results from the experiments showed mixed outcomes: while some demonstrations indicated cue competition, others suggested it wasn't as strong as anticipated by existing theories of associative learning.
