随着可用选项数量的增加和选择集变得更加复杂，决策往往变得更具挑战性。在多个选项之间进行选择可能需要额外的信息处理时间和精力。在这里，我们问，如果响应时间增加与刺激数量和吸引力的女性青蛙（酸浆）和他们的捕食者，食蛙蝙蝠（Trachops cadessus），当比较交配呼叫男性túngara青蛙。我们发现，青蛙的反应时间显着更长时，提出了两个电话，相比之下，一个。蝙蝠也需要更长的时间来回应时，提出了两个呼吁，但只有当他们是复杂的呼吁。虽然青蛙和蝙蝠在这个实验中的行为有些相似，但这些动物所做的决定发生在不同的领域（交配与觅食），并具有不同的适应性后果。鉴于这些差异，我们发现特别有趣的是，对于青蛙和蝙蝠，我们看到类似的时间模式的响应时间作为信息负载的函数。动物经常同时面临几种选择。决策的一个成本是在一个选择集中选择最佳选项所需的时间。在这里，我们问雌性青蛙和吃青蛙的蝙蝠是否需要更长的时间来响应时，同时提出多个青蛙交配呼叫。我们还询问了这些青蛙叫声的吸引力是否会影响青蛙和蝙蝠对它们做出反应的时间。我们发现，响应时间的影响，无论是蝙蝠和青蛙的青蛙呼叫的数量和吸引力;然而，青蛙的响应时间似乎更大的影响，青蛙呼叫的数量，而蝙蝠的响应时间似乎更受青蛙呼叫的吸引力。总的来说，我们的研究结果表明，这两种动物的决策可能涉及类似的机制。
Decisions tend to become more challenging as the number of available options increases and choice sets become more complex. Choosing between multiple options may require additional information processing time and effort. Here, we asked if response time increases with stimulus number and attractiveness by female frogs (Physalaemus pustulosus) and their predators, frog-eating bats (Trachops cirrhosus), when comparing the mating calls of male túngara frogs. We found that frogs’ response time is significantly longer when presented with two calls, compared with one. Bats also take longer to respond when presented with two calls but only when they were complex calls. Although the frogs and bats behave somewhat similarly in this experiment, the decisions that these animals are making are occurring in different domains (mating vs. foraging) and have different fitness consequences. Given these differences, we find it especially interesting that for both frogs and bats, we see similar temporal patterns in response times as a function of information load. Animals are often faced with several options simultaneously. One cost of decision-making is the time involved in choosing the best option within a choice set. Here, we asked whether female frogs and frog-eating bats take longer to respond when presented multiple frog mating calls simultaneously. We also asked whether the attractiveness of those frog calls influences the time it takes frogs and bats to respond to them. We found that the time to respond was influenced by both the number and attractiveness of frog calls for both bats and frogs; however, frog response time seemed to be more greatly influenced by the number of frog calls, while bat response time seemed to be more influenced by the attractiveness of frog calls. In general, our results suggest that there may be similar mechanisms involved in decision-making for both animals.
