Abstract: In social foraging situations, some group members search for their food sources (Producers), while others join previously discovered food sources (Scroungers). Associative learning has been crucial in understanding how individuals anticipate biologically significant events. The study aims to evaluate the effect of the presence or absence of the conditioned stimulus (CS) on the proportion of producer strategies. Eight golden fish were divided into two groups: Control and Pavlovian Group. The Pavlovian group was individually exposed to Pavlovian training under a delayed protocol. Subsequently, they were assigned to five sub-groups of different proportions of pre-trained fishes and exposed to a social foraging situation. Regarding Pavlovian acquisition, the latency between the onset of the conditioned stimulus and the entry responses into the patch zone increased as the sessions progressed. Concerning the social foraging situation, the study results indicated that the producer index was higher for fish pre-exposed to Pavlovian contingencies when the conditional stimulus was present. This research is of interest due to the relatively limited exploration of individual differences and the effects of learning in the context of the producer-scrounger game.

Abstract: In social foraging situations, individuals tend to employ one of two mutually exclusive strategies: 1) search for their own resources (Producer) or 2) steal or join previously discovered food sources (Scrounger). Information gain is a factor that allows the identification of food sources and the positions of other organisms. This study aimed to evaluate the effect of information gain on the proportion of producer-scrounger responses. The experimental task consisted of a virtual habitat where participants could move a virtual character in search of resources. Four conditions were manipulated, varying in camera angle (45 and 75 degrees) and distance (80 and 240 pixels), with two reinforcement probabilities (0.8 and 0.2). The results show that the proportion of producers was higher in conditions with greater camera distance. Furthermore, the generalized matching law reveals that undermatching was more pronounced in the lower probability conditions. The effect of perspective on the discrimination of patch locations and other participants is discussed.
