One of the main applications of the logic of theory change is to the epistemic analysis of conditionals via the so-called Ramsey test. In the first part of the present note this test is studied in the limiting case where the theory being revised is inconsistent, and it is shown that this case manifests an intrinsic incompatibility between the Ramsey test and the AGM postulate of success. The paper then analyses the use of the postulate of success, and a weakening of it, generating axioms of conditional logic via the test, and it is shown that for certain purposes both success and weak success are quite superfluous. This suggests the proposal of abandoning both success and weak success entirely, thus permitting retention of the postulate of preservation discarded by Gärdenfors. 相似文献

Two experiments examined the task interference that sometimes accrues from having an intention. In standard prospective memory
tasks, latency is often slower to an ongoing task performed concurrently with having an intention than it is when no intention
is given. If the locus of this slowing resulted from different attentional allocation policies in the two cases, we predicted
that the process of learning a word list would be impaired if participants had an intention rather than if they did not. Four
different event-based prospective memory tasks were used in Experiment 1 to demonstrate that worse free recall of a word list
resulted when studied with a concurrent intention than with a control condition that had no intention. In that experiment,
linking an intention to a distal context that was to occur after learning did not impair free recall. Two time-based tasks
were used in Experiment 2 to demonstrate that possessing a time-based prospective memory also hinders learning, unless the
intention is linked to a future context that is expected to occur after the study session. In the latter case, no impairment
was obtained. 相似文献

The testing effect is the finding that prior retrieval of information from memory will result in better subsequent memory for that material. One explanation for these effects is that initial free recall testing increases the recollective details for tested information, which then becomes more available during a subsequent test phase. In three experiments we explored this hypothesis using a source-monitoring test phase after the initial free recall tests. We discovered that memory is differentially enhanced for certain recollective details depending on the nature of the free recall task. Thus further research needs to be conducted to specify how different kinds of memorial details are enhanced by free recall testing. 相似文献

We conducted three experiments to examine the dynamics of a delayed‐execute prospective memory task involving task interruptions. In the delayed‐execute paradigm, participants must delay a response until some future condition is met. After an intention was formed to a salient cue, an interruption reduced prospective memory relative to a no‐interruption condition. Prospective memory for cues encountered during an interrupting task was worse than for cues occurring before an interruption, but the location of the cue in either the ongoing task or the interruption did not affect prospective memory. Importantly, reinstating the prevailing context after the interruption alleviated the negative influence of the interruption. Providing participants with information about the future context for making the delayed‐execute response also alleviated some of these deficits presumably because participants could encode more specific features of the performance context. These results highlight the potential importance of contextual associations and reminders in completing everyday intentions successfully. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
