“…Such discriminative ability extends to the genus Melipona (Menzel, Ventura, Werner, Joaquim, & Backhaus, 1989; Moreno, de Souza, & Reinhard, 2012;Pessotti, 1972), which was used in the present study. Bees can also master discriminative tasks that involve stimuli of different sensory modalities such as colors and odors (Giurfa et al, 2001;Reinhard, Srinivasan, Guez, & Zhang, 2004;Srinivasan, Zhang, & Zhu, 1998), and tasks that involve arbitrary relations between colors and temperatures (Dyer, Whitney, Arnold, Glover, & Chittka, 2006).…”

“…In fact, the results for baseline acquisition were somewhat unexpected for this experiment. Prior studies of visual discriminative learning in bees indicated that less than 100 training trials were required to establish a robust discriminative baseline (Giurfa et al, 2001;Moreno et al, 2012;Pessotti, 1972). For example, in the study by Moreno et al,16 bees received simple discrimination training with horizontal vs. vertical patterns and blue vs. yellow colors.…”

This study established a simple simultaneous discrimination between a pair of two-element compound visual stimuli in children (Experiment 1) and bees (Melipona quadrifasciata, Experiment 2). The contingencies required discriminative control by the compound and the question was whether the accurate stimulus control reached at this level would hold for each individual element of the compound. After baseline reached stability, probe trials assessed stimulus control by each single element of both S+ and S-. Average data showed that children (Exp. 1) tended to show stimulus control by a single element of the S+ compound. In Experiment 2 three of four bees showed stimulus control by both elements of S+ and did not respond or responded only infrequently to the elements of the S-. The children's decline in discrimination accuracy in probe trials, along with its maintenance during the baseline, replicated previous findings showing the development of restricted stimulus control (RSC). The precise stimulus control shown by the bees indicated that all elements correlated with reinforcement acquired stimulus control over their behavior; this confirms the extensive literature on visual discriminative learning in bees, but due to the small number of subjects it is premature to say that bees do not develop RSC.

“…Tipicamente, esses estudos são conduzidos em laboratórios nos quais uma ou mais colmeias são posicionadas junto a janelas da instalação, e algum aparato experimental é montado no interior do laboratório (e.g., Moreno, de Souza, & Reinhard, 2012). Desse modo, as abelhas não ficam confinadas.…”

O aparato usado no treino consistia em um túnel de madeira que terminava com duas saídas em Y. Nos dois braços terminais eram posicionados verticalmente os estímulos discriminativos.…”

RESUMOCom exceção dos estudos pioneiros de Isaías Pessotti sobre aprendizagem discriminativa em abelhas, outros trabalhos frequentemente empregaram procedimentos com características que dificultam o controle experimental rigoroso e uma interpretação segura dos dados (por exemplo, definição ambígua da resposta, treino simultâneo de vários sujeitos e análise de dados agrupados). Além disso, poucos estudos investigaram a aprendizagem discriminativa em outras espécies além de Apis mellifera e Bombus terrestris. O objetivo do Experimento 1 foi estabelecer discriminações simples entre cores e entre padrões em preto e branco em vinte abelhas individuais, da espécie Melipona quadrifasciata. No Experimento 2, o objetivo foi estabelecer discriminações simples e reversões de discriminação com quatro melíponas individuais em equipamento automatizado e pressão à barra como resposta operante. Todas as abelhas aprenderam a discriminar entre cores no Experimento 1, mas os dados de discriminação entre padrões em preto e branco mostraram grande variabilidade. No Experimento 2, as quatro abelhas aprenderam a discriminação inicial e também aprenderam entre uma e 11 reversões de discriminação. Os resultados de ambos os experimentos confirmam que melíponas podem aprender tarefas discriminativas, incluindo reversões sucessivas, mas também sugerem que os desempenhos podem variar consideravelmente a depender dos estímulos a serem discriminados.Palavras-chave: discriminação simples, reversão de discriminação, estímulos visuais, abelhas, Melipona quadrifasciata ABSTRACT Except for the pioneering work of Isaías Pessotti on discriminative learning in bees, other studies often employed procedures that hinder rigorous experimental control and make difficult the data interpretation (e.g., ambiguous definition of the response, simultaneous training of various subjects, and analysis of pooled data). Moreover, few studies have investigated the discriminative learning in species other than Apis mellifera and Bombus terrestris. The purpose of Experiment 1 was to establish simple discrimination between colors and between black and white patterns, in twenty individual bees of the species Melipona quadrifasciata. In Experiment 2, the objective was to establish simple discrimination and discrimination reversals with four individual bees using electro-mechanical equipment and a bar press response. All the bees learned to discriminate between colors in Experiment 1, but discriminations between black and white patterns showed high individual differences. In Experiment 2, the four bees learned the initial discrimination and also learned from one to 11 discrimination reversals. The results of both experiments confirm that Meliponidae can learn visual discriminations, including successive reversals, but the data also suggest that performance may vary considerably depending on the discriminative stimuli.

Simple and conditional discrimination training may produce various types of controlling relations. Responses may be controlled primarily by the positive stimulus (select-control relation) or by the negative stimulus (reject-control relation; the subject excludes the negative stimulus and chooses the positive). Bees learn to respond in simple and conditional discriminations. However, no study has searched for reject-control responding in Melipona bees. We trained Melipona quadrifasciata on a simple discrimination task (S+ vs. S-; e.g., blue vs. yellow) and then probed for stimulus control with two types of probe trials, S+ versus a new stimulus (Select-control probes) and S-versus a new stimulus (Reject-control probes). For Group Different, a newstimulus color (e.g., white) was used in one type of probe and another color (e.g., black) was used in the other type. For Group Same, a single new-stimulus color was used in both types of probes. On Select probes, the bees always preferred S+ to the new stimulus. On Reject probes, results were mixed. Depending on the colors used in training and probing, bees responded to both stimuli, and even preferred the S-. The data suggest no control by the negative function of the S-and support the select-stimulus control hypothesis of responding.
