Two experiments are reported which were designed to investigate the generality and the power of the mechanisms underlying
sequence learning. In both experiments, participants reacted to systematic sequences of tones. They were informed that there
was a tone systematicity. Participants were not told that the interval between a response to a tone and the onset of the subsequent
tone (response-signal interval, RSI) also varied according to a fixed regularity. Experiment 1 showed that the unattended
RSIs were learned when they were uniquely related to the tone sequence, but not when the relation was ambiguous. Experiment
2 showed that, on the basis of the traditional reaction time performance measure, participants who learned the RSIs by attending
to their systematicity could not be distinguished from those in an incidental learning condition in which the RSI systematicity
was unattended. However, a model-based analysis of the processes contributing to judgements about the event sequences suggested
that the two groups had acquired qualitatively different knowledge.

Four experiments examined the effect of category cueing on recall-to-reject, one of the central memory-editing mechanisms thought to prevent the occurrence of false memories. When category names were used as retrieval cues, the typically observed false recognition effect was eliminated for semantically associated distractors (Experiment 1a) and, moreover, a reduction in the absolute level of the false alarm rate was found for phonologically associated distractors (Experiment 2a). In addition to the old/new-recognition data, analyses using multinomial models support the interpretation that category cueing was successful in increasing the probability of recall-to-reject (Experiments 1b and 2b). The results are in line with dual-process theories of recognition memory and provide further evidence for recall-to-reject in single item recognition. They demonstrate its potential to reduce false recognition even when explicit instructions are not given. In addition, the results demonstrate that the paradigm can give rise to side effects that oppose recall-to-reject. A simultaneous familiarity increase can explain why many studies failed to find evidence for recall-to-reject in terms of false alarm rates. 相似文献

Nicola Döring and Alex Gundolf's article on the development of 'moblogs' or mobile weblogs allows us to approach recent mobile phone industry developments from an academic standpoint. Pointing to the convergence of mobile and Internet technology, 'moblogs' provide a means for users to archive their lives via photos that can be taken via a mobile phone and viewed via the Internet. Nokia have named their product to provide this service 'lifeblog', and it is this uncensored publication of everyday life that Döring and Gundolf investigate, from subjects as mundane as a user capturing his waking state everyday, to as personally and globally historic as the moblog by a US soldier in Iraq. What we are seeing in the 'moblog' is how organically some product development is in the mobile world--the early moblogging software came not from operators, handset or software manufacturers but from the social software community that thrives on the Internet. It is precisely this level of organic, spontaneous product development that occurs as a by-product of networked communities that many companies seek and often fail to emulate. 相似文献

At present, it is not well understood which individual characteristics determine whether individuals will benefit or suffer from feedback about suboptimal performance. Three separate studies tested the idea that individuals' reactions to (neutral versus negative; positive versus negative) feedback as either improving or deteriorating performance in intelligence tests depended on their explicit and implicit self‐concept of intelligence (eSCI and iSCI). In all studies (Study 1, N = 177; Study 2, N = 165; Study 3, N = 132), persons with low eSCI/high iSCI showed a boost in performance after negative feedback, whereas persons with any other combination showed a decline in performance. The studies also provide an explanation for these effects in terms of mediating mechanisms. Whereas the performance boost of individuals with low eSCI/high iSCI can be best explained by achievement‐related reactance (Studies 2 and 3) and decrease in ruminative thinking (Study 3), the performance declines in the other configurations were mediated by decreased achievement motivation, increased frustration and increased outrage (Study 3). All these mediating mechanisms proved independent and incremental in a bootstrapping‐based moderated meditation analysis. The results are discussed in light of the construct validity of our Implicit Association Test (IAT) and IATs in general. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
