Visual illusions allow for strong tests of perceptual functioning. Perceptual impairments can produce superior task performance on certain tasks (i.e., more veridical perception), thereby avoiding generalized deficit confounds while tapping mechanisms that are largely outside of conscious control. Using a task based on the Ebbinghaus illusion, a perceptual phenomenon where the perceived size of a central target object is affected by the size of surrounding inducers, we tested hypotheses related to visual integration in deaf (n = 31) and hearing (n = 34) patients with schizophrenia. In past studies, psychiatrically healthy samples displayed increased visual integration relative to schizophrenia samples and thus were less able to correctly judge target sizes. Deafness, and especially the use of sign language, leads to heightened sensitivity to peripheral visual cues and increased sensitivity to visual context. Therefore, relative to hearing subjects, deaf subjects were expected to display increased context sensitivity (ie, a more normal illusion effect as evidenced by a decreased ability to correctly judge central target sizes). Confirming the hypothesis, deaf signers were significantly more sensitive to the illusion than nonsigning hearing patients. Moreover, an earlier age of sign language acquisition, higher levels of linguistic ability, and shorter illness duration were significantly related to increased context sensitivity. As predicted, disorganization was associated with reduced context sensitivity for all subjects. The primary implications of these data are that perceptual organization impairment in schizophrenia is plastic and that it is related to a broader failure in coordinating cognitive activity.

Despite the considerable research that has been carried out on cross-cultural pat terns of political conflict, little empirical attention has been devoted to the study of blood feuds. In this study, coding categories were developed to measure the legitimacy of kin group vengeance, self-redress, and formal adjudication mechanisms among societies in the Standard Cross-Cultural Sample (Murdock and White 1969). The empirical results strongly suggest that blood feuds occur within the context of marriage bargains and that they are most characteristic of societies studied prior to World WarI. When historical time penod and other potential external influences were considered, feuding was found to be associated primarily with premarital chastity concerns and mode of marriage. Individual self-redress and formal adjudication, however, depend on characteristics of the political economy-economic resource base, stratification, diverging devolution, and hospitable climate. It is suggested here that future analyses of political conflict should distinguish feuds from other forms and take into account the historical effects of Western incursions on the internal politics of traditional communities.

Individuals involved in the criminal justice (CJ) system continue to be at disproportionate risk for HIV infection, and often have a greater prevalence of substance use and sexual related risk behaviors relative to their non-CJ involved peers. Pre-exposure prophylaxis (PrEP), a once daily antiretroviral medicine, is an evidence-based approach for reducing the risk of contracting HIV but limited data exist regarding the use of PrEP among CJ populations, especially in the U.S. South. This study was conducted at the Pulaski County Regional Detention Facility (PCRDF) in Little Rock, Arkansas (AR), the largest county jail in the state. We explored knowledge about PrEP and HIV, perceptions about PrEP feasibility in both the jail and community settings and barriers to PrEP program implementation, through in-depth qualitative interviews with 21 jail detainees. We purposively sampled individuals based on specific self-reported risk behavior, including sexual risk (both heterosexual and same-sex) and drug related risk (e.g. IDU), among all eligible individuals. We identified five primary themes from the interviews: 1) accessing healthcare during community reentry was a low priority; 2) perception of risk and interaction with people with HIV was low; 3) there are many barriers to disclosing HIV risk behaviors in jail settings; 4) knowledge of PrEP is low but willingness to use is high; and 5) multiple barriers exist to PrEP uptake post-release. Our findings are contextually unique and therefore have important implications for future implementation of PrEP access either within jail settings or linkage to PrEP post release.

Cognition has become prominent in the study of schizophrenia because of its importance for understanding the etiology of the illness and its consequences for living independently. For people with schizophrenia who are also deaf, investigations of cognition and schizophrenia are infrequent. This study examines the role of linguistic ability in relation to cognition, social cognition, and functional outcome among deaf adults with schizophrenia or schizoaffective disorder. The primary finding is that linguistic ability is positively and significantly associated with functional outcome above and beyond the contribution of cognition and social cognition. A younger age of sign language acquisition is significantly associated with superior linguistic ability, but did not moderate the effect of linguistic ability on other domains. Opportunities for deaf mental health consumers to participate in sign language enrichment programs and communicate with other skilled signers may be useful additions to standard psychiatric rehabilitation programming. More research is needed to clarify the consequences of deafness with regards to schizophrenia especially as it relates to language, vision, and symptoms.
