Visual attention was studied in a group of rhesus monkey infants whose mothers received daily oral treatment with low levels of δ9-tetrahydrocannabinol (THC, 2.4 mg/kg/day) prior to and during pregnancy and throughout lactation (3.5 postnatal months). Attention was measured at 1 and 2 years of age in a standardized test situation in which animals looked at projected slides. In comparison with controls (offspring of untreated mothers), THC offspring directed more attention at slides on the 1st trial of session. The THC offspring also engaged in relatively longer individual periods of attention on the 1st vs 2nd trials of the session and during the 1st vs 2nd session in which a given slide was presented. Further experiments varying novelty and complexity of visual stimuli suggested that changes in visual attention of THC offspring can be characterized as a failure to limit the response to novel stimuli.
