Cerebral lateralization is the process of selective partitioning of cognitive functions into the left or right hemisphere of the brain. It is an evolutionarily ancient adaptation prevalent across vertebrates and invertebrates. Lateralization offers advantages such as enhanced cognitive capacity and multitasking abilities. However, lateralization patterns can be intricate and influenced by both intrinsic factors such as sex and extrinsic factors such as emotional valence. Lateralization patterns show substantial variation, and it has been known to be affected by factors such as emotion, sociality, familiarity, sex, personality-like traits, and others. The studies presented in this thesis have been conducted to examine the influence of such factors on lateralization along with other relationships in the kribensis (Pelvicachromis pulcher). Fish have laterally placed eyes with limited visual field overlap. I used asymmetry in eye use towards stimulus in lateralization tasks as a measure of cerebral lateralization. My thesis shows lateralization is a plastic, context-dependent trait. Lateralization patterns in the kribensis exhibit significant sex differences and are associated with personality-like traits such as activity.
