“…The present study offers some support for a social-learning model in that the self-administration behavior of a peer, as opposed to merely the presence of a peer, determined the reinforcing strength of cocaine. Findings such as these are consistent with a large body of literature indicating that modeling and social reinforcement influence responding maintained by nondrug reinforcers (see Angermeier, 1960; Heyes et al, 1992; Evans et al, 1994; Akins and Zentall, 1996; Akins et al, 2002). These findings also extend those from several recent studies examining proximal social factors (i.e., those present at the time of testing) on measures of drug reinforcement.…”

Social-learning theories of substance use propose that members of peer groups influence the drug use of other members by selectively modeling, reinforcing, and punishing either abstinence-related or drug-related behaviors. The objective of the present study was to examine social influences on cocaine self-administration in isolated and socially housed rats, with the caveat that the socially housed rats were tested simultaneously with their partner in the same chamber. To this end, male rats were obtained at weaning and housed in isolated or pair-housed conditions for 6 weeks. Rats were then implanted with intravenous catheters and cocaine self-administration was examined in custom-built operant conditioning chambers that allowed two rats to be tested simultaneously. For some socially housed subjects, both rats had simultaneous access to cocaine; for others, only one rat of the pair had access to cocaine. An econometric analysis was applied to the data, and the reinforcing strength of cocaine was measured by examining consumption (i.e., quantity demanded) and elasticity of demand as a function of price, which was manipulated by varying the dose and ratio requirements on a fixed ratio schedule of reinforcement. Cocaine consumption decreased as a function of price in all groups. Elasticity of demand did not vary across groups, but consumption was significantly lower in socially housed rats paired with a rat without access to cocaine. These data suggest that the presence of an abstaining peer decreases the reinforcing strength of cocaine, thus supporting the development of social interventions in drug abuse prevention and treatment programs.

“…Physical contact with another member of the same species can itself be rewarding too (Angermeir, 1960). In our study we demonstrated the reward value of interacting with a familiar partner in adult WT mice in the SCPP task.…”

Disrupted-in-schizophrenia-1 (DISC1) is associated with mental disorders, including major depression. We previously showed that DISC1-Q31L mutant mice have depression-like behaviors and can therefore be used to study neurobiological mechanisms of depression and antidepressant (AD) medication action. First, we found reduced levels of dopamine, serotonin and norepinephrine in the nucleus accumbens (NAC) of DISC1-Q31L mutants. Next, we assessed social-conditioned place preference as a reward-dependent task and the capacity of distinct ADs to correct impaired social behavior in DISC1-Q31L mice. Bupropion, but not fluoxetine or desipramine, was able to correct deficient social facilitation, social reward, and social novelty in DISC1-Q31L mutants, whereas all three ADs were able to improve social motivation and behavioral despair in DISC1-Q31L mutants. Furthermore, we sought to correlate social anhedonia with molecular and cellular features including dendritic spine density, β-arrestin-1,2, and cAMP-response-element-binding protein (CREB) in the NAC as biomarkers related to depression and the DISC1 pathway. DISC1-Q31L mutants showed reduced levels of β-arrestin-1,2, CREB, and spine density in the NAC, further supporting the construct validity of the genetic model. Bupropion induced the greatest effect on CREB in DISC1-Q31L mutants, whereas all studied ADs corrected the reduced levels of β-arrestin-1,2 and modestly ameliorated deficient spine density in this brain region. Overall, we find neurobiological changes accompanying social anhedonia in the NAC of DISC1-Q31L mutant mice, consistent with a role for DISC1 in regulating social reward as an endophenotype of depression.

“…However, other investigators have presented evidence favoring the necessity of an association between the social stimi~lus and another more traditional reinforcer, thus assigning a secondary reinforcement property to the social stimulus (Mason, 1961). Angermeier (1960) has investigated some components of social reinforcement with comparisons between visual, partial physical, and full physical contact. H e has shown differential effects of these components in animals otherwise reared in isolation from these stimuli.…”

In order to isolate the effectiveness of some components of social reinforcement given to the dog by the human, precise measurements were recorded of six dogs' performance in a disciplined training program. Both verbal praise and petting were used as rewards. When petting was discontinued, verbal praise alone was not sufficient to maintain performance. However, performance was re-established when petting was again added in a later phase of the experiment. The authors conclude that the evidence is supportive of h e thesis that some kinds of tactile stimulation are of a primaty reinforcement nature to the dog.
