Hypocrite's Guide to Forgetting
2. Be silent for two minutes.
3. Carry on as before.
Adolescent Cannabis ExposureI think the key phrase here is 'modest autoshaping'.
"The rats were exposed to THC... In order to mimic the intermittent use seen in teenagers, the drug was given once every third day; this resulted in a total of eight injections. One week after the last injection, heroin self-administration (outlined below) was initiated in one set of animals and brains were taken in another group of rats for post-mortem studies."
Intravenous Heroin Self-Administration
"The animals were first trained to self-administer intravenous infusions of 15 g/kg heroin. After 6 days, the dose of heroin was increased to 30 g/kg/infusion and the rats received one priming infusion at the start of the following 1–4 sessions, until they started to press on their own."
"None of the rats acquired self-administration at the heroin dose of 15 g/kg/infusion during the time period studied. When the dose was increased to 30 g/kg/infusion and in combination with modest autoshaping (one drug prime and food restriction), all animals acquired self-administration behavior."
"Confirmatory factor analysis of the item set has shown previously that the items formed a unidimensional scale reflecting the extent of psychotic symptomatology."Meaning, as I wrote in a previous post, that they'd already proven that all the psychotic symptoms they'd listed are equal in weight, and together make up the full range of symptoms. Nice work if you can get it.
