When participants ignore an irrelevant distractor they typically show impaired responding to that item if it becomes the relevant stimulus on a subsequent trial. In Experiment 1 (N = 64), a masked white colour name was presented briefly before a Stroop display. Negative priming in colour naming occurred when the colour of the lettering for the Stroop stimulus matched the colour name displayed in the first display, consistent with the proposal of temporal discrimination theory that negative priming arises because a recurrence of an unattended stimulus cannot readily be classified as old or new. Experiment 2 (N = 32) replicated negative priming in the interleaved-word display where participants had to name the red word from a pair of red and green words. In Experiment 3 (N = 32) and Experiment 4 (N = 28) the participants were required to attend to but not respond to the words in the prime display and name one of two interleaved words in the probe display. Negative priming was observed in this arrangement, consistent with the episodic retrieval theory of negative priming. The temporal discrimination model may need to be extended to situations in which the attended stimuli have different responses attached to them.

Culture-negative peritoneal inflammation accounts for between 5 and 20% of cases of peritonitis in peritoneal dialysis patients. Diagnostic yields may be enhanced considerably by reculturing dialysate effluents using appropriate collection methods and optimal laboratory techniques (including prolonged low-temperature and anaerobic incubations). In patients with persistent culture-negative peritonitis, consideration should be given to the possibilities of unusual or fastidious microorganisms (especially fungi and mycobacteria) and non-infective causes (especially drug reactions, malignancy, visceral inflammation and retroperitoneal inflammation). In this paper, an illustrative case of persistent culture-negative peritonitis is presented followed by a discussion of the investigative approach to such patients, with particular emphasis on differential diagnosis and the limitations of currently available tests.
