“…Not until the age of 4 years righthanded behaviour predominates and unilateral hand preference is well established at the age of 9 (Gesell & Ames 1947). Therefore, the data suggest that although predispositions for lateralization are present already early in ontogeny, handedness is still open to environmental influences later in life, much as early predispositions for motor patterns (courtship postures and calls) and cognition (imprinting on the mother) in birds can still be modified in later life ( Johnson et al 1985;Groothuis 1993). …”

Despite several decades of research, the epigenesis of behavioural and brain lateralization is still elusive, although its knowledge is important in understanding developmental plasticity, function and evolution of lateralization, and its relationship with developmental disorders. Over the last decades, it has become clear that behavioural lateralization is not restricted to humans, but a fundamental principle in the organization of behaviour in vertebrates. This has opened the possibility of extending descriptive studies on human lateralization with descriptive and experimental studies on other vertebrate species. In this review, we therefore explore the evidence for the role of genes and environment on behavioural lateralization in humans and other animals. First, we discuss the predominant genetic models for human handedness, and conclude that their explanatory power alone is not sufficient, leaving, together with ambiguous results from adoption studies and selection experiments in animals, ample opportunity for a role of environmental factors. Next, we discuss the potential influence of such factors, including perinatal asymmetrical perception induced by asymmetrical head position or parental care, and social modulation, both in humans and other vertebrates, presenting some evidence from our own work on the domestic chick. We conclude that both perinatal asymmetrical perception and later social modulation are likely candidates in influencing the degree or strength of lateralization in both humans and other vertebrates. However, in most cases unequivocal evidence for this is lacking and we will point out further avenues for research.

“…However, despite the fact that early social behavior can be of great importance for survival (Mock and Parker, 1997), not much is known about the influence of gonadal hormones on social behavior early in ontogeny. In avian species, early treatment with testosterone can induce precocial social display and copulatory behavior (for a review, see Groothuis, 1993), but the function of gonadal hormones in the regulation of social behavior of young birds under natural condition is still largely unexplored. Recently, the hormonal basis of sibling competition has attracted some attention, but the data do not yet show a coherent picture.…”

“…Still, young black-headed gulls might before this time show temporary increases in levels of testosterone that play a role in aggressive interactions [29]. Earlier studies showed that this increase in sex steroids and aggressive behaviour can be suppressed by preventing the gulls to be exposed to aggressive challenges from other gulls [1,29]. Therefore birds of different cages were isolated from visual communication with each other.…”

“…It is well known that social experience plays an important role in the development of social behaviour [1][2][3], while many aggressive and courtship behaviours are facilitated by sex steroids like testosterone and estradiol [4]. The aim of this paper is to study how social experience might interact with these facilitating effects of sex steroids.…”

Experience modulates both aromatase activity and the sensitivity of agonistic behaviour to testosterone in black-headed gulls Ros, Albert F. H.; Franco, Aldina M.

In young black-headed gulls (Larus ridibundus), exposure to testosterone increases the sensitivity of agonistic behaviour to a subsequent exposure to this hormone. The aim of this paper is twofold: to analyze whether social experience, gained during testosterone exposure, mediates this increase in hormonal sensitivity (priming), and whether this in turn is mediated by an increase in central aromatase activity. To this end, we performed three experiments. In the first juvenile gulls were exposed to two consecutive treatments with testosterone (T1 and T2), with more than a week interval in between. During T1, half of the birds were housed in social isolation (Iso) and the other half in groups (Soc). All birds were re-housed in a new social situation during the second treatment. The increase in social behaviour during T2 was significantly more rapid in Soc than Iso birds. In experiment 2 we show that 17β-estradiol treatment facilitates the behaviour measured in experiment 1. In experiment 3 we used a set-up comparable with that of experiment 1, but birds were sacrificed early in the T2 period. Aromatase activity in the preoptic area and the hypothalamus was measured using the tritiated water releasing method. In some parts of the preoptic area and hypothalamus aromatase activity was higher in Soc birds relative to Iso birds. The results indicate that social experience can modulate the increase of social behaviour to testosterone via modulation of aromatase activity and independently of actual hormone levels.
