| Abstract | The effects of caffeine on free recall after acquisition on semantic and rhyming tasks were examined. Following a between-subjects design, high and low impulsive male postgraduate students were administered placebo and four doses of caffeine citrate (1, 2, 3 and 4 mg/kg body weight) in a laboratory situation. A double blind procedure was adopted for drug administration. The study supports the following conclusions: (1) under no drug condition, high impulsives recall more after semantic acquisition while their counterparts, the low impulsives, recall more after rhyming acquisition; (2) caffeine facilitates recall in high impulsives after rhyming acquisition but hinders it after semantic acquisition; (3) caffeine does not reliably influence recall of low impulsives. |
