Effect Of Environmental Enrichment On The Acquisition Of Sign-Tracking Of An Ethanol Bottle In The Home Environment, Amanda Pra Sisto
Effect Of Environmental Enrichment On The Acquisition Of Sign-Tracking Of An Ethanol Bottle In The Home Environment, Amanda Pra Sisto
Seton Hall University Dissertations and Theses (ETDs)
Sign tracking is a Pavlovian conditioning procedure that has been used in preclinical drug-addiction research with rats to investigate individual differences in the attribution of incentive motivational value to reward cues that may lead to problematic behavior such as drug addiction. Animals demonstrate a tendency to interact with an object conditioned stimulus (CS) that signals the presentation or delivery of a reward, even though the delivery of the reward is independent of any interaction with the stimulus. Thus, it can be argued that sign tracking is a compulsive-like behavior, or an indication of compulsive “wanting” that is associated with increased …
Social Transmission Of Ethanol Preference In A Sign-Tracking Paradigm, Pat Severino
Social Transmission Of Ethanol Preference In A Sign-Tracking Paradigm, Pat Severino
Seton Hall University Dissertations and Theses (ETDs)
The Observer/ Demonstrator Effect suggests that rats can socially obtain preferences for novel foods/drugs by interacting with experienced conspecifics. Sign-tracking is a paradigm which uses a conditioning procedure to evoke compulsive-like behaviors directed towards a tangible conditioned stimulus (CS) paired with a motivating unconditioned stimulus (US). The present study investigated the possibility that increased alcohol use results from the combination of socially transmitted cues and the kind of conditioning effect seen in sign-tracking procedures. Therefore, it was hypothesized that social exposure to an alcohol-experienced conspecific would summate with the conditioning experience and increase the sign-tracking of a bottle CS containing …
Do Rats Consume Ethanol To Regulate A Negative Emotion Induced By A Successive Negative Contrast Procedure?, Andrew Dieterich
Do Rats Consume Ethanol To Regulate A Negative Emotion Induced By A Successive Negative Contrast Procedure?, Andrew Dieterich
Seton Hall University Dissertations and Theses (ETDs)
According to the self-medication hypothesis, individuals may consume drugs or alcohol, or engage in other behaviors in order to reduce a negative emotional state (Khantzian, 1985; Gross, 2013; Crum et al., 2013). Rats experiencing a negative state induced by various stressors (Bertholomey et al., 2010), or a decrease or loss in reward value of a sucrose solution (Manzo et al., 2015; Manzo et al., 2014) demonstrate increased consumption of alcohol. I used successive (SNC) and anticipatory negative contrast (ANC) procedures to further examine this hypothesis and the previous findings (Manzo et al., 2015), that rats increase consumption and preference for …
