When we see combinations of text and graphics, such as photographs and their captions in printed media, how do we compare the information in the two components? Two experiments used a sentence-picture verification task in which statements about photographs of natural scenes were read in order to make a true/false decision about the validity of the sentence, and in which eye movements were recorded. In Experiment 1 the sentence and the picture were presented concurrently, and objects and words could be inspected in any order. In Experiment 2 the two components were presented one after the other, either picture first or sentence first. Fixation durations on pictures were characteristically longer than those on sentences in both experiments, and fixations on sentences varied according to whether they were being encoded as abstract propositions or as coreferents of objects depicted in a previously inspected picture. The decision time data present a difficulty for existing models of sentence verification tasks, with an inconsistent pattern of differences between true and false trials. 相似文献

In Experiment 1 rats were presented with two flavours, A and B, that were accompanied either by a third common flavour, X, or by two different flavours, X and Y, respectively. An aversion was then established to A, and the extent to which this aversion generalized to B was measured. Stimulus generalization was found to be more marked when A and B had both been presented with the same flavour, X, during pre-exposure than when A and B had been presented with X and Y. In Experiment 2 three target flavours, A, B, and C, were initially presented. In one pre-exposure condition presentations of A and B were accompanied by X, and C was presented alone; in a second condition A and B were presented in isolation, and C was accompanied by X. After an aversion had been established to A, half of the animals in each of the pre-exposure conditions were tested with B, and the remainder were tested with C. In both of the pre-exposure conditions the generalized aversion was more substantial to B than to C. An analysis of these results in terms of the mechanisms that have been supposed to underlie sensory preconditioning is presented. 相似文献

This study aimed to assess sexual risk behaviour and its social correlates in HIV-infected women living in rural South Africa at six and twelve months post-partum. Participants were 699 HIV-positive women recruited prenatally by systematic sampling from twelve community health centres in Mpumalanga province, South Africa (mean age = 28.4 years, SD = 5.7; married =41.1%; serodiscordant or unknown partner status = 74.9%). They self-reported on their sexual activity six to twelve months after delivery; including use of condoms and partner involvement. Generalised linear mixed models were utilised to estimate unsafe sex outcomes from a prevention of mother to child transmission (PMTCT) intervention, socio-demographic factors, disclosure, and male involvement. About 20% of sexually active women in the past week had used condoms inconsistently at six and twelve months after delivery. Moreover, 16% and 18% of the women had not used a condom at last sex and 11% and 13% had unprotected sex with HIV-uninfected or unknown-status partners following delivery at six and twelve months, respectively. Higher inconsistent condom use was likely with lower male involvement. Promotion of condom use post-partum, as well as male involvement in sexual decisions, are important for safer sex post-partum by seropositive women. 相似文献
