Lateralized behaviour in the domestic cat, Felis silvestris catus

Lateralized behaviour in the felids has been subject to little investigation. We examined the paw use of 42 domestic cats on three tasks designed to determine whether the animals performed asymmetrical motor behaviour. The influence of the cats' sex and age on their paw preferences was also explored. The distribution of the cats' paw preferences differed significantly between the three tasks. Task 1, the most complex exercise involving retrieval of a food treat from an empty jar, encouraged the most apparent display of lateralized behaviour, with all but one animal showing a strong preference to use either their left or right paw consistently. Tasks 2 (an exercise involving reaching for a toy suspended overhead) and 3 (a challenge involving reaching for a toy moving along the ground) encouraged ambilateral motor performance. Lateralized behaviour was strongly sex related. Male and female cats showed paw preferences at the level of the population, but in opposite directions. Females had a greater preference for using their right paw; males were more inclined to adopt their left paw. Feline age was unrelated to either strength or direction of preferred paw use. Overall, the findings suggest that there are two distinct populations of paw preference in the cat that cluster strongly around the animals' sex. The results also point to a relationship between lateralized behaviour and task complexity. More apparent patterns of lateralized behaviour were evident on more complex manipulatory tasks, hinting at functional brain specialization in this species. © 2009 The Association for the Study of Animal Behaviour.

The ontogenesis of lateralized behavior in the domestic cat, Felis silvestris catus

For the first time, the development of paw preferences in the domestic cat, Felis silvestris catus, is explored. Twelve cats were tested at ages 12 weeks, 6 months, and 1 year on a challenge requiring them to use one of their paws to retrieve food. To control for repeated testing of the same cats at different ages, the subjects' paw preferences were compared with those of cats tested just once, at 6 months (n = 11) or 1 year (n = 14) of age. Analysis revealed a significant effect of age on the distribution of cats' paw preferences. Cats were significantly more likely to be ambilateral than paw preferent at 12 weeks and at 6 months but more likely to display a lateral bias in paw use at 1 year. There was a significant positive correlation between cats' paw preferences at 6 months and at 1 year. Lateralized behavior was strongly sex related. Females had a greater preference for using their right paw; males were significantly more inclined to adopt their left. Analysis revealed no significant difference in the direction or strength of paw preferences of cats tested longitudinally or cross-sectionally at 6 months or 1 year of age. Findings indicate that cats develop paw preferences by 1 year and hint at a relative stability in preferred paw use over time. The strong sex effect observed strengthens the case for the influence of a biological mechanism in the emergence of motor asymmetry in cats.

Plus ça change: (Post)Colonial Timor-Leste as a Return to (Pre)Colonial Realities in the Novels of Luis Cardoso

This article examines the novels of the East Timorese writer Luís Cardoso, and argues that their representations of a colonial past should not be simply interpreted as memorializations of Timor-Leste’s suffering at the hands of foreign aggressors. It proposes that underlying their revisiting of the past is a call for acknowledgement of the agency of East Timorese in the history of violent conflict that has troubled the nation, and that only this can guarantee true reconciliation, justice and national independence.

A Cat's Lick: Democratisation and Minority Communities in the Post-Soviet Baltic

The research on Estonia, Latvia and Lithuania has pointed out some controversial social and political developments since the collapse of the Soviet Union. Crucially, there is a discrepancy between the governments' commitment to creating democratic political regimes, to ensuring harmonious social relations and to accommodating the ethno-cultural diversity of the resident communities. In reflecting on the legacies of the Soviet past, the book addresses the role non-titular populations have played in the process of democratisation and the relation between the states, societies and minorities in the post-Soviet Baltic states. The argument proceeds along three lines. Firstly, the book examines the institutional dimension of democratisation in the region, thereby addressing the processes of state- and nation-building as reflected in various policy-developments. Secondly, it compares the impact of ethno-cultural diversity on the development of the respective Baltic nation-states. The discussion makes clear that the framework of Baltic political communities was designed to suit the interests of the titular groups and thus resulted in the marginalisation of the minority communities. Thirdly, the book assesses the participation of minority communities in the development, criticism and improvement of state institutions and policies since independence. The analysis points out that, two decades after independence, the post-Soviet Baltic states and societies are seen by many members of the majority groups as primarily serving the interests of their ethnic community. In this situation, the members of the non-titular communities need to adapt to the majorities' perceptions in order to benefit from the achievements of democratisation.
