The illusion of perceived line length produced by the parallel lines configuration reverses from assimilation to contrast with large spatial separation of the contextual and test lines (Jordan & Schiano, 1986). In the present experiment, we tested whether length contrast is produced by the sequential sampling of contextual and test lines or by the(More)
Three experiments were designed to investigate whether the characteristic function relating response time to stimulus orientation reflects the observer imagining the rotation of the stimulus to upright (the "image rotation" hypothesis) or rotation of an internal reference frame in response to the misoriented stimulus (the "frame rotation" hypothesis).(More)
Effective control of the intracellular protozoan parasite Toxoplasma gondii depends on the activation of antigen-specific CD8(+) T-cells that manage acute disease and prevent recrudescence during chronic infection. T-cell activation in turn, requires presentation of parasite antigens by MHC-I molecules on the surface of antigen presenting cells. CD8(+)(More)
Protective immunity to Toxoplasma gondii, an intracellular protozoan parasite, is characterized by a strongly polarized Th1-mediated immune response that is dependent on CD4+ and CD8+ T cells. In order to study the factors that influence development of CD8+ T cell responses to this parasite, a system was developed using a replication-deficient parasite that(More)
