The effect of alcohol consumption on recency discrimination ability: an early screening test for alcohol-induced cognitive impairment.
Alderdice FA., Davidson R.
In this short study the relationship between recency discrimination ability and a measure of alcohol intake was examined using a series of regression analyses. Semi-partial correlations were extracted in order to evaluate which variables (level of alcohol consumption, age and IQ) best predicted recency discrimination performance on both verbal and non-verbal tasks. Results showed that while IQ best predicted performance on the verbal task both IQ and alcohol intake were significant predictors on the non-verbal task. The results are discussed in relation to current findings and the continuity hypothesis.
