Vicarious trauma: The psychological impact of working with survivors of trauma for South African psychologists

Traumatic events are highly prevalent in South African society and psychologists who work with survivors of trauma have been identified as particularly at risk of being adversely affected by their work, and experiencing vicarious trauma. This study aimed to explore the experiences of a group of South African psychologists who work predominantly with trauma survivors. Individual semi-structured interviews were conducted with six psychologists (females = 67%). The predominant type of trauma encountered by participants in clinical practice was interpersonal trauma in the form of physical and sexual abuse (83%). Data were analysed using thematic analysis. All participants reported symptoms of vicarious trauma including disruption in cognitive schemas, symptoms characteristic of post-traumatic stress disorder, and somatic symptoms. Participants also reported vicarious post-traumatic growth including an enhanced sense of interpersonal connectedness and positive changes in their philosophy of life and self-perceptions. The findings serve to sensitise psychologists to the impact of working with trauma survivors so as to enhance the efficiency of psychological service delivery to traumatised populations.     

Accommodating Presuppositions Is Inappropriate in Implausible Contexts

According to one view of linguistic information (Karttunen, 1974; Stalnaker, 1974), a speaker can convey contextually new information in one of two ways: (a) by asserting the content as new information; or (b) by presupposing the content as given information which would then have to be accommodated. This distinction predicts that it is conversationally more appropriate to assert implausible information rather than presuppose it (e.g., von Fintel, 2008; Heim, 1992; Stalnaker, 2002). A second view rejects the assumption that presuppositions are accommodated; instead, presuppositions are assimilated into asserted content and both are correspondingly open to challenge (e.g., Gazdar, 1979; van der Sandt, 1992). Under this view, we should not expect to find a difference in conversational appropriateness between asserting implausible information and presupposing it. To distinguish between these two views of linguistic information, we performed two self‐paced reading experiments with an on‐line stops‐making‐sense judgment. The results of the two experiments—using the presupposition triggers the and too—show that accommodation is inappropriate (makes less sense) relative to non‐presuppositional controls when the presupposed information is implausible but not when it is plausible. These results provide support for the first view of linguistic information: the contrast in implausible contexts can only be explained if there is a presupposition‐assertion distinction and accommodation is a mechanism dedicated to reasoning about presuppositions.     

On the Margin: Power and Women's HIV Risk Reduction Strategies

HIV risk and prevention research has failed to investigate adequately the effects of gender-related factors such as relationship power, sexual communication, abuse, and gender roles on women's abilities to engage in protective actions. We propose that women's HIV risk from heterosexual transmission is embedded in the context of gender, race/ethnicity, and class oppression. This context has central implications for interpersonal relationship factors relevant to women's HIV risk. We suggest a framework for understanding women's HIV risk within the context of oppression and the role of power in intimate sexual relationships. Three common dynamics of oppression are considered: (1) Silencing, (2) Violence and Fear of Violence, and (3) Internalized Oppression. These dynamics are based on characteristics of oppression discussed in the work of Jean Baker Miller on gender, Hussain Bulhan on race, and Paulo Freire on class. These dynamics are discussed in the context of findings reported in this journal issue and those of other authors. Finally, the discussion identifies common patterns across studies, as well as areas of disagreement and directions for future research and public health prevention efforts.     

Immigrant acculturation attitudes and host country identification

This study assessed the efficacy of a model predicting the host country identification of members of immigrant groups. The model proposed that host country identification is primarily determined by the positivity of the immigrants' acculturation attitude towards living according to the standards and values of the host country, followed by the degree of acceptance by members of the dominant cultural group, the success immigrants experience in the new country, and the extent to which they choose to live within their ethnic environment rather than the wider society. The study included 602 adult immigrants from a number of countries (Vietnam, People's Republic of China, Hong Kong, Taiwan, Sri Lanka, and New Zealand), which varied in their cultural similarity to the host country, Australia. Results from a multiple regression analysis of participants' questionnaire responses revealed good support for the model. As expected, acculturation attitude towards Australia was the strongest predictor of host country identification, followed by acceptance by Australians, while extent of ethnic involvement was a significant negative predictor. The results also revealed ethnic identification as a significant positive predictor of host country identification. The importance of the relationship between acculturation attitudes and identification is discussed, together with immigrants' identification processes towards their ethnic group and the host country.

Processing focus structure and implicit prosody during reading: differential ERP effects

Several recent studies have shown that focus structural representations influence syntactic processing during reading, while other studies have shown that implicit prosody plays an important role in the understanding of written language. Up until now, the relationship between these two processes has been mostly disregarded. The present study disentangles the roles of focus structure and accent placement in reading by reporting event-related brain potential (ERP) data on the processing of contrastive ellipses. The results reveal a positive-going waveform (350-1300 ms) that correlates with focus structural processing and a negativity (450-650 ms) interpreted as the correlate of implicit prosodic processing. The results suggest that the assignment of focus as well as accent placement are obligatory processes during reading.     

Programs and logics

We use the algebraic theory of programs as in Blikle [2], Mazurkiewicz [5] in order to show that the difference between programs with and without recursion is of the same kind as that between cut free Gentzen type formalizations of predicate and prepositional logics.     

The Freedom of Thought: Patočka on Descartes and Husserl

Pato?ka highlights the central role of Cartesianism in our tradition of thinking. Yet, today, brain scientists often claim to have overcome Cartesian dualism. In this paper, I argue that the Cartesian conceptions of human nature and sensory perception remain presuppositions of brain science, where perception is largely equated with thinking. Equating perception and thinking means that thinking is a determined process, which leads to an erosion of critique. Critique, and the freedom of thought it entails, is essential to Descartes, Husserl and Pato?ka. I examine the differences, as well as the relationship, between Descartes method of doubt, Husserl’s phenomenological epochē and Pato?ka’s universalization of the epochē. I also show how Descartes’, Husserl’s and Pato?ka’s way into critique present different ways to understand self, things and the world. In conclusion, I suggest that Pato?ka presents a promising way to critique mechanistic understandings of thinking by rethinking both subject and object.
