The authors evaluated the relative contributions of speed, memory, and visual scanning to Digit Symbol score in a sample of young adults (N = 87). Speed (Symbol Copy) explained 35% of Digit Symbol variance; only half of this was attributable to graphomotor speed (Name Printing), implying a role for perceptual speed. Visual-scanning tests (e.g., Symbol Scan) explained (on average) 34% of Digit Symbol variance, much of which was independent of perceptual-motor speed, establishing an important role for visual-scanning efficiency in Digit Symbol performance. By contrast, memory tests (on average) explained only 4% to 5% of Digit Symbol variance: statistically significant but clearly subsidiary, although a visual memory composite correlated more strongly with Digit Symbol. The Digit Symbol incidental learning procedures did, however, correlate moderately with other memory measures, suggesting that they are valid memory screening devices. 相似文献

One of the alleged reasons that males report lower intimacy in same-sex friendships than females is that males tend to be more competitive than females, but this assumption has not been empirically tested. In the current study, 121 Hong Kong adolescents filled out Chinese versions of the Intimate Friendship Scale and the Competitiveness Index. As predicted, females reported having more intimate same-sex relationships than males, and they scored lower on competitiveness than males. However, the correlations between scores on the Competitiveness Index and the Intimate Friendship subscales were small and nonsignificant, suggesting that the sex difference in intimacy was not a function of competitiveness. 相似文献

Honeybees were trained to find sugar water in the middle of an array of two landmarks of different colours. Unrewarded tests
compared searching on the training array with searching on rotated arrays. On rotated tests, a system using the angles between
landmarks would continue to search in the middle. A system using vectors to individual elements would search at locations
outside the rotated array at which the distances and compass directions to a subset of landmarks matched. Results indicated
that bees used both elements and interlandmark angles, but they relied most on one favourite landmark element. Results support
the template model of landmark use in honeybees, with the minor parametric modification that weights given to different elements
may be unequal.

Perception of classroom environment in Hong Kong: differences between students in junior and senior forms 总被引:2,自引:0,他引:2
Cheng ST 《Adolescence》1999,34(136):793-798
In Hong Kong secondary schools, students in the senior forms take competitive examinations to proceed to the next level, whereas those in the junior forms have to attend school regardless of their ability and motivation. It was hypothesized that this produces different classroom climates. To test this hypothesis, 602 Chinese secondary school students were administered the short version of the Classroom Environment Scale. Significant differences were found, varying by type of school, on the dimensions of Involvement, Task Orientation, Teacher Support, Competition, Order and Organization, Affiliation, Innovation, Rule Clarity, and Teacher Control. These findings are discussed. 相似文献

The type of experience involved with an object category has been regarded as one important factor in shaping of the human
object recognition system. Laboratory training studies have shown that different kinds of learning experience with the same
set of novel objects resulted in different perceptual and neural changes. Whether this applies to natural real-world objects
remains to be seen. We compared two groups of observers who had different learning experiences with faces, using holistic
processing as a dependent measure. We found that, while ordinary observers had extensive individuation experience with faces
and displayed typical holistic face processing, art students who had acquired additional experience in drawing faces, and
thus in attending to parts of a face, showed less holistic processing than did ordinary observers. These results converge
with laboratory training studies on the role of type of experience in the development of different perceptual markers for
different object categories. It is thus insufficient to categorize expertise simply in terms of object domains (e.g., expertise
with faces). Instead, perceptual expertise should be classified in terms of the underlying process or task demand. 相似文献

情绪记忆增强(Emotionally Enhanced Memory, EEM)效应受到刺激的唤醒度和效价的影响。Kensinger 等人提出依赖于唤醒的 EEM 效应与自动加工相联系,依赖于效价的 EEM 效应与控制加工相联系。然而现有研究并不能为这一假设提供充分的证据。本研究的三个实验采用学习--再认范式和 DA 范式(divided attention paradigm)相结合的方法,分别考察了在两种注意条件下依赖于唤醒和依赖于效价的EEM 效应在编码阶段的加工机制。结果发现,中性词、正性非唤醒词、负性非唤醒词在集中注意条件下的记忆再认成绩显著高于分散注意条件下的记忆再认成绩;正性唤醒词在集中注意条件下的记忆再认成绩也显著高于分散注意条件下的记忆再认成绩,但负性唤醒词的记忆再认成绩在两种注意条件下不存在显著差异。这表明依赖于效价的 EEM 效应与控制加工相联系,而依赖于唤醒的 EEM 效应并不总是与自动加工相联系,其加工还受到情绪效价的调节,对于负性刺激,依赖于唤醒的 EEM 效应与自动加工相联系;对于正性刺激,依赖于唤醒的EEM效应则与控制加工相联系。 相似文献

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public. 相似文献
