Abstract

HOSHINO, Katsumasa; CARAMASCHI, Sandro; CLAUDIA DA SILVA, Ana  and  MICHELAN, Lílian Daltro. Cerebral hemispheric specialization and behavioral asymmetries: does the side of bed have a gender?. Rev. etol. [online]. 2011, vol.10, n.2, pp. 83-91. ISSN 1517-2805.

Data relative on the side occupied by females in double beds were collected in order to evaluate the feasebility to carry-out a more extensive study to determine if this behavioral pattern is lateralized. Information relative to the side occupied in the bed, manual lateralization, how long lived togheter, and other related questions were collected in a sample of 229 women aged from 20 to 65 years old. Total frequencies of the bed side occupied showed to be equivalent, however, the left side showed to be chosen significantly more (70%)(Χ² = 5.4; 1 d.f.; p<0.05) when the choice was stated to be spontaneous (i.e, not determined by an impositive factor). It is concluded that the obtained data give favourable support to an extensive study on the subject, which inserts into the area of research devoted to the understanding of the functional characteristics of central nervous functioning.

Keywords : Lateral dominance; Hemispheric specialization; Emotions; Gender differences.
