The motivation of the study is to investigate the reinforcing potential of an invasive weed species (water hyacinth) for subgrade reinforcement and juxtapose its reinforcing efficacy with that of the conventionally used coir and jute fibers.
Since, according to MPR, a yields a numerical index of the value of the food reinforcer, the present results provide quantitative confirmation of evidence from previous studies which indicated that destruction of the STN may enhance the reinforcing efficacy of positive reinforcers [10,47 49].
Additionally, mice with a genetic deletion of presynaptic D2 autoreceptors show increased reinforcing efficacy of food, suggesting that decreased autoreceptor regulation augments reward and reinforcement for both natural and drug rewards.
However, the involvement of 5-HT2 receptors in the interaction between the serotonergic system and the reinforcing efficacy still remains equivocal.
Sibling pairs with greater differences in relative reinforcing efficacy and delay discounting had greater differences in zBMI.
Behavioral choice theory and laboratory choice paradigms can provide a framework to understand the reinforcing efficacy or reinforcing value of food.
Experimental results indicated that the reinforcing efficacy of the amorphous matrix was higher than the semi-crystalline matrix at temperatures below the glass transition.
These results support the notion of a negative influence of increased serotonergic neurotransmission on reinforcing efficacy of drugs that act via monoamine systems.
Conclusions: The combination of greater sibling pair differences in delay discounting and relative reinforcing efficacy is associated with greater discordance in zBMI in adolescent sibling pairs.
Reinforcing efficacy is measured in the laboratory by assessing how much effort one will engage in to gain access to food as the amount of work progressively increases.
