Brain lateralization research has led to speculation about counseling and guidance implications of left-right brain differences. Serious limitations in these implications are highlighted.  相似文献

A taxonomy of part-whole or meronymic relations is developed to explain the ordinary English-speaker's use of the term “part of” and its cognates. The resulting classification yields six types of meronymic relations: 1. component-integral object (pedal-bike), 2. member-collection (ship-fleet), 3. portion-mass (slice-pie), 4. stuff-object (steel-car), 5. feature-activity (paying-shopping), and 6. place-area (Everglades-Florida). Meronymic relations ore further distinguished from other inclusion relations, such as spatial inclusion, and class inclusion, and from several other semantic relations: attribution, attachment, and ownership. This taxonomy is then used to explain cases of apparent intransitivity in merological syllogisms, and standard form syllogisms whose premises express different inclusion relations. The data suggest that intransitivities arise due to equivocations between different types of semantic relations. These results are then explained by means of the relation element theory which accounts for the character and behavior of semantic relations in terms of more primitive relational elements. The inferential phenomena observed are then explained by means of a single principle of element matching.  相似文献

Developing readers often make anagrammatical errors (e.g. misreading pirates as parties), suggesting they use letter position flexibly during word recognition. However, while it is widely assumed that the occurrence of these errors decreases with increases in reading skill, empirical evidence to support this distinction is lacking. Accordingly, we compared the performance of developing child readers (aged 8–10 years) against the end‐state performance of skilled adult readers in a timed naming task, employing anagrams used previously in this area of research. Moreover, to explore the use of letter position by developing readers and skilled adult readers more fully, we used anagrams which, to form another word, required letter transpositions over only interior letter positions, or both interior and exterior letter positions. The patterns of effects across these two anagram types for the two groups of readers were very similar. In particular, both groups showed similarly slowed response times (and developing readers increased errors) for anagrams requiring only interior letter transpositions but not for anagrams that required exterior letter transpositions. This similarity in the naming performance of developing readers and skilled adult readers suggests that the end‐state skilled use of letter position is established earlier during reading development than is widely assumed.  相似文献
