Modeling Trajectories of Sensation Seeking and Impulsivity Dimensions from Early to Late Adolescence: Universal Trends or Distinct Sub-groups?

Developmental imbalance models attribute the rise in risk-taking during adolescence to a universal imbalance between rising reward sensitivity and lagging cognitive control. This study tested predictions of an alternate Lifespan Wisdom Model that distinguishes between exploratory/adaptive (e.g., sensation seeking) and maladaptive (e.g., acting-without-thinking, delay discounting) risk-taking propensities and attributes the latter to a sub-set of youth with weak cognitive control. Latent trajectory modeling of six waves of data from 387 adolescents (52% females; spanning average ages of 11–18 years) revealed distinct sub-groups with heterogeneous trajectory patterns for acting-without-thinking and delay-discounting. Only those trajectory groups with weak cognitive control, characterized as “high-increasing” acting-without thinking and “high-stable” delay discounting were predictive of a maladaptive risk-taking outcome, namely substance use disorder. Sensation seeking demonstrated a universal peak, but high levels of sensation seeking were not associated with weakness in cognitive control and were unrelated to substance use disorder, controlling for impulsivity. The findings suggest that maladaptive risk-taking characterized by weak cognitive control over reward-driven impulses is a phenomenon limited to only a sub-set of youth.     

Heterosexuality and Race in the Australian Same-Sex Marriage Postal Survey

ABSTRACT

This article argues that race and class are central aspects of sexual citizenship in a Australia. It does so by investigating representations of heterosexuality that were produced and circulated during the 2017 same-sex marriage postal survey. Engaging with feminist and critical race theorists, we position same-sex marriage as not exceptional but part of a wider distribution of sexual citizenship within Australia's ongoing settler colonial history. We do so by introducing a number of illustrative examples of representations of heterosexuality produced during the survey. These representations reveal how same-sex marriage perpetuated heterosexual authority by asserting claims to authenticity and the occupation of space. We observe how heterosexuality in the survey material reproduced fantasies linking these three themes, for example, in an authentic white heterosexual family who speaks from their suburban backyard. It reveals that ceding to a bifurcated view of either progressive or conservative voices forestalls rather than advances other visions which may exceed the limited imaginings of sexual citizenship offered by the white liberal settler colonial state.     

Racial animosity and political party partisanship in South Africa: the case of the African National Congress and the Black African majority

As it is in many countries, racial rhetoric is a feature of South African national government elections. The use of such rhetoric provokes the question, how much is political party support in the country driven by interracial animosities? Using the nationally representative public opinion dataset, the South African Social Attitudes Survey, this article looks at party closeness to the African National Congress (ANC) amongst the black African population. The ANC is one of the oldest and most powerful political parties on the African continent and currently dominates South Africa’s parliamentary government. Constructing four indexes of racial attitudes and behaviours, the article investigates whether partisanship with the ruling party can be predicted by racial animosity. The period under investigation is 2010–2014. Bivariate and multivariate quantitative techniques are employed to test the relationship between ANC partisanship and racial animosity. The results of this investigation show that racial enmity in the country is troublingly widespread. Public opinion analysis, however, found no correlation between racial acrimony and ANC partisanship. Other factors are driving black African identification with the country’s ruling party. The implications of these results for the study for political party support in South Africa are discussed and future avenues of research presented.
