The goal of this dissertation was to evaluate proximate mechanisms that facilitate incest avoidance, and elucidate under what circumstances these mechanisms may fail, integrating insights from the fields of forensic and evolutionary psychology. To set the stage, Study 1 was a meta-analysis that examined differences between biological and sociolegal incest offenders on two major risk dimensions (antisociality and atypical interests). While sociolegal incest offenders were more problematic on some indicators of antisociality, these groups did not differ in atypical sexual interests. These findings suggest that current models of child sexual abuse may not be sufficient to fully explain incest offending. Studies 2 and 3 examined the viability of the Westermarck hypothesis (1891/1921) - that early physical proximity leads to incest avoidance - and the mediating role of disgust in father-daughter (Study 2) and brother-sister (Study 3) relationships. The primary hypothesis for these studies was that disgust toward incest would mediate the relationship between physical proximity and incest propensity or behaviour. The results of Study 2 did not support the Westermarck hypothesis among fathers. While physical proximity may not activate incest avoidance in fathers, disgust toward incest may still be a proximate mechanism. The results of Study 3 were consistent with the Westermarck hypothesis and the mediating role of disgust as an incest avoidance mechanism among siblings, and also suggest that moderators, such as sexual behaviour that could result in offspring, could influence the strength of this mechanism. These findings suggest that mechanisms responsible for incest avoidance may be different for fathers and siblings.

[pt] A presente dissertação tem como objetivo mapear os anais do Congresso Brasileiro de Assistentes Sociais (CBAS) dos anos de 2001 e de 2022. Além disso, se propõe a examinar a discussão acerca do trabalho profissional de assistentes sociais no sociojurídico mediante a análise da produção acadêmico-profissional sobre este espaço socio-ocupacional. Para o estudo aqui apresentado, foram desenvolvidos levantamentos nos anais do X Congresso Brasileiro de Assistentes Sociais – CBAS (2001) e do XVII Congresso Brasileiro de Assistentes Sociais (2022). Também foram consideradas contribuições do conjunto formado pelo Conselho Federal de Serviço Social (CFESS) e pelos Conselhos Regionais de Serviço Social (CRESS) acerca do sociojurídico na área do Serviço Social, bem como os rebatimentos do contexto societário da pandemia da Covid-19 neste campo de atuação profissional. Considerando os períodos dos anais do Congresso Brasileiro de Assistentes Sociais (CBAS) estudados, verificou-se um número reduzido de produções acadêmico-profissionais sobre esse espaço ocupacional, não obstante o CBAS de 2001 ter sido um marco importante para reflexões sobre o sociojurídico. Além disso, o estudo indicou a verificação da necessidade de continuidade do debate acerca do trabalho profissional no sociojurídico, pois é prejudicial, tanto aos profissionais quanto aos estudantes de Serviço Social, não haver mais espaços de reflexões, eventos e produção acadêmico-profissional de maneira contínua acerca deste tema, que atravessa um espaço de trabalho importante para o Serviço Social desde a sua constituição como profissão no país. / [en] The present master s thesis aims to map the annals of the Brazilian Congress of Social Workers (CBAS) from 2001 and 2022. In addition, it proposes to examine the discussion about the professional work of social workers in the socio-legal field through the analysis of the academic-professional production on this socio-occupational space. For the study presented here, surveys were developed in the annals of the X Brazilian Congress of Social Workers - CBAS (2001) and the XVII Brazilian Congress of Social Workers (2022). Contributions from the group formed by the Federal Council of Social Service (CFESS) and the Regional Councils of Social Service (CRESS) regarding socio-legal issues in the area of Social Service were also considered, as well as the repercussions of the societal context of the Covid-19 pandemic in this field of professional activity. Considering the periods studied in the annals of the Brazilian Congress of Social Workers (CBAS), there was a reduced number of academic-professional productions on this occupational space, despite the fact that the 2001 CBAS was an important milestone for reflections on socio-legal issues. Furthermore, the study indicated the need for continued debate on professional work in socio-legal issues, o it is detrimental to both professionals and students of Social Work if there are no more spaces for reflection, events and academic-professional production on a continuous basis on this topic, which has been an important area of work for Social Work since its establishment as a profession in Brazil.
