This study shows that the classical phonological similarity effect (PSE) in immediate serial recall is critically affected by the lexicality of list items, the type of phonological similarity involved, and the scoring procedure. PSE was present in the serial recall score when phonologically distinct words were compared to words that share the middle vowel and end consonant (rhyming lists). PSE was absent in the serial recall score when phonologically distinct words were compared to words that share the initial and final consonants (consonant frame lists). There was a reversal of PSE in serial recall of nonwords when comparing distinct lists to both types of similar lists. Recall accuracy on the other hand was higher for distinct lists regardless of lexicality. Item errors dominated in relation to order errors in the case of nonwords, whereas order errors dominated in relation to item errors in the case of words. Furthermore, order errors were more common for phonologically similar lists, whereas item errors were more common for phonologically distinct lists. This may be the result of intra-list and inter-list interference, respectively. The dominance of the former error type may cause a classical PSE, whereas the dominance of the latter error type may cause a reversal of PSE. Finally, an item identification task yielded no evidence of an association between intra-list interference and discriminability of items in a list. 相似文献

Feelings of existential guilt are assumed to depend on the perception of a causal relationship between one's own behavior or (privileged) situation and the disadvantages of others. By contrast, pity should not depend on such perceptions. This hypothesis, which has been supported so far only by correlational studies, was tested experimentally. Eighty students were shown a film about a developing country. The film was provided with four different comments, each representing one experimental condition (between-subjects design). Experimental factors were "amount of misery of the people shown" and "subject's responsibility for these peoples' conditions of life". As expected, subjects in the condition "misery and responsibility" reported higher feelings of guilt, though no more pity than subjects in the remaining three treatment conditions (experiment 1, n = 40). This mean difference, however, was statistically significant for men only. Contrary to our theoretical expectations--and to finding from other experiments on vicarious reparation--the induction of guilt had no effect on willingness to help a third party (experiment 2, n = 40). Possible reasons for this unexpected finding are suggested. 相似文献

In most studies on animal learning, individual animals are tested separately in a specific learning environment and with a limited number of trials per day. An alternative approach is to test animals in a familiar environment in their social group. In this study, the authors--applying a fully automated learning device--investigated voluntary, self-controlled visual shape discrimination learning of group-housed dwarf goats (Capra hircus). The majority of the tested goats showed successful shape discrimination, which indicates the adaptive value of an effective learning strategy. However, in each group, a few individual goats developed behavioral strategies different from shape discrimination to get reward. Relocation impairs memory retrieval (probably by attention shifting) only temporarily for previously learnt shapes. The results demonstrate the usefulness of a self-controlled learning paradigm to assess learning abilities of social species in their normal social settings. This may be especially relevant for captive animals to improve their welfare. 相似文献

In a study of the internal category structure of the vowel /i/, Kuhl found a “perceptual magnet effect”: Discrimination sensitivity
was poorer for category instances that were acoustically similar to the category prototype than it was for category instances
that were not. The typicality of category exemplars was determined by goodness judgments and was found to correlate with the
acoustics of average production. Analysis and interpretation of discrimination performance relied on two important assumptions:
that listeners perceived all stimuli presented as exemplars of the same vowel category and that, apart from the influence
of phonetic coding, discrimination sensitivity was the same across the investigated part of the vowel space. In the present
study, it is shown that production and perception estimates of the category prototype may diverge, possibly because listeners
seem to prefer hyperarticulated variants of vowel categories. An approach towards measurement of intra-category discrimination
minima is put forward and tested that protects against intercategory confounds and avoids the isosensitivity assumption.

In a wide variety of publications,1 Johannes B. Metz programatically represented a new political theology of subject, society, history, and future. This theology participates intensely in the lively, ongoing discourse on the political and theological actuality and significance of the critical theory of society, religion and future set forth by the Marxist, Walter Benjamin.2 The purpose of this study is to illuminate several connections between Benjamin's critical theory and Metz's political theology, particularly with respect to the present stage of development in advanced capitalistic society and to their future. 相似文献
