“…between boldness and aggressiveness). Correlations among the fast-slow BTs include the observation that foraging activity in the absence of predators is often correlated with boldness when predators are present [64], with aggressiveness in contests [15,65], with mating tactics [66,67], with patterns of parental care [13] and with dispersal tendencies [16,35,68].…”

With the exception of a few model species, individual differences in cognition remain relatively unstudied in non-human animals. One intriguing possibility is that variation in cognition is functionally related to variation in personality. Here, we review some examples and present hypotheses on relationships between personality (or behavioural syndromes) and individual differences in cognitive style. Our hypotheses are based largely on a connection between fast-slow behavioural types (BTs; e.g. boldness, aggressiveness, exploration tendency) and cognitive speed -accuracy trade-offs. We also discuss connections between BTs, cognition and ecologically important aspects of decision-making, including sampling, impulsivity, risk sensitivity and choosiness. Finally, we introduce the notion of cognition syndromes, and apply ideas from theories on adaptive behavioural syndromes to generate predictions on cognition syndromes.

“…Consider, for example, aggressive fishing spiders that tend to be highly successful in catching prey. Interspecific aggression, however, is correlated with intraspecific aggression, and aggressive females have a low mating success, since they tend to attack and cannibalize males before copulation [6]. In these and many other examples (e.g.…”

On the coevolution of social responsiveness and behavioural consistency

Recent research focuses on animal personalities, that is individual differences in behaviour that are consistent across contexts and over time. From an adaptive perspective, such limited behavioural plasticity is surprising, since a more flexible structure of behaviour should provide a selective advantage. Here, we argue that consistency can be advantageous because it makes individuals predictable. Predictability, however, can only be advantageous if at least some individuals in the population respond to individual differences. Consequently, the evolution of consistency and responsiveness are mutually dependent. We present a general analysis of this coevolutionary feedback for scenarios that can be represented as matrix games with two pure strategies (e.g. hawk-dove game, snowdrift game). We first show that responsive strategies are favoured whenever some individual differences are present in the population (e.g. due to mutation and drift). We then show that the presence of responsive individuals can trigger a coevolutionary process between responsiveness and consistency that gives rise to populations in which responsive individuals coexist with unresponsive individuals who show high levels of adaptive consistency in their behaviour. Next to providing an adaptive explanation for consistency, our results also link two key features associated with personalities, individual differences in responsiveness and behavioural consistency.

“…Such consistency can generate trade-offs, such that levels of inherent aggressiveness may be appropriate in some functional contexts but not others. For example, aggressive individuals may be more successful in defending resources such as food or territories from conspecifics but these same individuals may also display inappropriate aggression towards potential mates (Sih et al 2004;Johnson & Sih 2005). Recent work across a range of taxa that has explicitly focused on consistency in individual-level behavioural phenotypes suggests that aggression may play an important role in an individual's reproductive success and, to a lesser extent, its survival (Dingemanse & Reale 2005;Duckworth 2006a;Boon et al 2007;Reale et al 2007;Smith & Blumstein 2008).…”

Female aggression predicts mode of paternity acquisition in a social lizard

Individual differences in behaviour are ubiquitous in nature. Despite the likely role of selection in maintaining these differences, there are few demonstrations of their fitness consequences in wild populations and, consequently, the mechanisms that link behavioural variation to variation in fitness are poorly understood. Specifically, the consequences of consistent individual differences in behaviour for the evolution of social and mating strategies have rarely been considered. We examined the functional links between variation in female aggression and her social and mating strategies in a wild population of the social lizard Egernia whitii. We show that female Egernia exhibit temporally consistent aggressive phenotypes, which are unrelated to body size, territory size or social density. A female's aggressive phenotype, however, has strong links to her mode of paternity acquisition (within-versus extra-pair paternity), with more aggressive females having more offspring sired by extra-pair males than less aggressive females. We discuss the potential mechanisms by which female aggression could underpin mating strategies, such as the pursuit/acceptance of extra-pair copulations. We propose that a deeper understanding of the evolution and maintenance of social and mating systems may result from an explicit focus on individual-level female behavioural phenotypes and their relationship with key reproductive strategies.
