Critics noted that studies supporting the Low Level of Response Model only accounted for the negatively valenced sedative effects of alcohol and that while decreased sensitivity to aversive effects of alcohol would likely lead to increased drinking frequency and severity, the subjective effects of alcohol are, in actuality, quite varied.[1] For example, it is widely accepted that the rewarding properties of alcohol are reinforcing. Yet, according to the Low Level of Response Model, reduced sensitivity to these rewarding effects is an indicator of problematic drinking. To that end, critics have noted that in Schuckit's seminal SR study,[7] FH+ males experienced more "energy" than FH- males along rising BAC, suggesting that heightened sensitivity to the stimulating effects of alcohol may convey risk for developing alcohol problems.[3] Another study found that FH+ subjects reported experiencing less intoxication than FH- subjects in response to a placebo drink, indicating that alcohol expectancies may account for differences in risk more so than SR.[8] That is, individuals at greatest risk for developing alcohol use disorder may expect alcohol to be more enjoyable and less aversive than low-risk individuals.
