Graded interference effects were tested in a naming task, in parallel for objects and actions. Participants named either object or action pictures presented in the context of other pictures (blocks) that were either semantically very similar, or somewhat semantically similar or semantically dissimilar. We found that naming latencies for both object and action words were modulated by the semantic similarity between the exemplars in each block, providing evidence in both domains of graded semantic effects. 相似文献

Competition, cooperation, and the effects of others on me 总被引:3,自引:0,他引:3
Four studies were conducted to test the notion that whether one competes against or cooperates with a comparison target can serve as an important determinant of the direction (contrast or assimilation) of self-evaluative social comparison effects. In Study 1, cooperative-competitive orientation was treated as an individual difference variable, and it was shown that social comparison led to contrast for individuals with a more competitive orientation, whereas assimilation occurred for individuals with a more cooperative orientation. Study 2 replicated this result, treating cooperative-competitive orientation as a contextual variable. In Study 3, it was demonstrated that to obtain this pattern of results it is not necessary for perceivers to believe that they will be either competing or cooperating with the comparison target. Simply activating the relevant concepts is sufficient. The final studies demonstrated that competition activates a "difference" focus and cooperation activates a "similarity" focus. 相似文献

At least five earlier studies could not find effector-dependent learning in the keying version of the serial reaction time (RT) task. Experiment 1 examined whether effector-dependent learning occurs when participants practice the serial RT task with three fingers of one hand for about 1,300 sequence repetitions instead of the more common 50-100 repetitions. The results confirm that, following extended practice, sequence learning produces an effector-dependent component. Specifically, an unpracticed hand executed a practiced sequence slower than a practiced hand. However, Experiment 2 showed that effector-dependent sequence learning develops only when fingers of one hand are used, suggesting that effector-dependent sequence learning involves adjustment to the mechanical interactions between the fingers of one hand. In addition, when sequences had been practiced with one hand, mirror versions of the practiced sequences in both experiments showed moderate transfer. But when practiced with two hands no transfer to a mirrored version of the sequence was observed. This suggests that only practice with one hand produces a representation that facilitates the execution of mirror sequences. Generally, the same results were found in more or less aware participants, congruent with the idea that the effector-dependent representation and the representation allowing transfer to mirror sequences are implicit. 相似文献

Previous research has shown that the production of morphologically complex words in isolation is affected by the properties of morphologically, phonologically, or semantically similar words stored in the mental lexicon. We report five experiments with Dutch speakers that show that reading an inflectional word form in its linguistic context is also affected by analogical sets of formally similar words. Using the self-paced reading technique, we show in Experiments 1-3 that an incorrectly spelled suffix delays readers less if the incorrect spelling is in line with the spelling of verbal suffixes in other inflectional forms of the same verb. In Experiments 4 and 5, our use of the self-paced reading technique shows that formally similar words with different stems affect the reading of incorrect suffixal allomorphs on a given stem. These intra- and interparadigmatic effects in reading may be due to online processes or to the storage of incorrect forms resulting from analogical effects in production. 相似文献

Henri Tajfel's contribution to the experimental study of intergroup relations is highlighted and recent complementary approaches are presented. The distinction between deductive and inductive aspects of social categorization and the links between within group and between group interaction and differentiation are commented. A plea is made for studying self as social representation and for considering ethical issues of intergroup relations. 相似文献

Through external analysis of two-mode data one attempts to map the elements of one mode (e.g., attributes) as vectors in a fixed space of the elements of the other mode (e.g., stimuli). This type of analysis is extended to three-mode data, for instance, when the ratings are made by more individuals. It is described how alternating least squares algorithms for three-mode principal component analysis (PCA) are adapted to enable external analysis, and it is demonstrated that these techniques are useful for exploring differences in the individuals' mappings of the attribute vectors in the fixed stimulus space. Conditions are described under which individual differences may be ignored. External three-mode PCA is illustrated with data from a person perception experiment, designed after two studies by Rosenberg and his associates whose results were used as external information.We gratefully acknowledge the assistance of Piet Brouwer in implementing the external analysis options in the TUCKALS programs. 相似文献
