Pigeons' discrimination of paintings by Monet and Picasso

Pigeons successfully learned to discriminate color slides of paintings by Monet and Picasso. Following this training, they discriminated novel paintings by Monet and Picasso that had never been presented during the discrimination training. Furthermore, they showed generalization from Monet's to Cezanne's and Renoir's paintings or from Picasso's to Braque's and Matisse's paintings. These results suggest that pigeons' behavior can be controlled by complex visual stimuli in ways that suggest categorization. Upside-down images of Monet's paintings disrupted the discrimination, whereas inverted images of Picasso's did not. This result may indicate that the pigeons' behavior was controlled by objects depicted in impressionists' paintings but was not controlled by objects in cubists' paintings.     

On the continuing utility of argument in a postmodern world

In this essay we contend that traditional theories of argument are consonant with and enrich the project of postmodernity. Reading postmodernity as a rhetoric underscores how the process of discursively resolving conflicts is occasionally threatened by politically motivated efforts to misuse the methods of argument; it alerts us to the egregious acts that are and can be performed in the name of, but not because of, rationality. Postmodernity is thus an attempt by a new generation of theorists to recast and draw attention to perennial philosophical problems in the context of contemporary political difficulties.     

Responding changes systematically within sessions during conditioning procedures.

When the procedure is held constant within an experimental session, responding often changes systematically within that session. Many of these within-session changes in responding cannot be dismissed as learning curves or by-products of satiation. They have been observed in studies of positive reinforcement, avoidance, punishment, extinction, discrimination, delayed matching to sample, concept formation, maze and alley running, and laboratory analogues of foraging, as well as in the unconditioned substrates of conditioned behavior. When aversive stimuli are used, responding usually increases early in the session. When positive reinforcers are used, responding changes in a variety of ways, including increasing, decreasing, and bitonic functions. Both strong and minimal reinforcement procedures produce within-session decreases in positively reinforced behavior. Within-session changes in responding have substantial theoretical and methodological implications for research in conditioning.     

CONCEPTIONS OF SELF/NO-SELF AND MODES OF CONNECTION Comparative Soteriological Structures in Classical Chinese Thought

This essay examines the ways that the terms “self” and “no‐self” can illuminate the views of classical Chinese thinkers, particularly Confucians such as Confucius, Mencius, and Xunzi, and the Daoist thinker Zhuangzi. In particular, the use of the term “no‐self ” to describe Zhuangzi's position is defended. The concepts of self and no‐self are analyzed in relation to other terms within the thinkers' “concept clusters”—specifically temporality, nature, and social roles—and suggestions are given for constructing typologies that sort out the range of meanings of self and no‐self based on the characteristics of the relations among terms within the concept clusters. The essay focuses on the way that the Confucians and Zhuangzi use concepts of self and no‐self, respectively, as soteriological strategies that aim at making connections with larger systems or wholes, and it concludes that different connections are emphasized by the Confucians and Zhuangzi precisely because the various connections are made possible and sustained by different conceptions of self, temporality, nature, and social roles.     

The change in perceived motor competence and motor task values during elementary school: A longitudinal cohort study

Participation in motor activities is essential for social interaction and life satisfaction in children. Self‐perceptions and task values have a central position in why children do or do not participate in (motor) activities. Investigating developmental changes in motor self‐perceptions and motor task values in elementary school children would provide vital information about their participation in motor activities. We therefore examined the change in, and associations between, self‐perceptions and task values of fine motor competence, ball competence, and athletic competence in 292 children from kindergarten to grade 4. We also investigated differences between boys and girls, and between children with motor problems and typically developing children. Results indicated that self‐perceptions and task values are domain specific and differ between boys and girls, but not between children with motor problems and typically developing children. Self‐perceptions were not associated with task values. Educators should address specific self‐perceptions to enhance participation into the corresponding motor activities in children between kindergarten and grade 4, and differences in self‐perceptions and task values between boys and girls should be taken into account.     

Developmental changes in the embodied self of spatial perspective taking

Spatial perspective taking consists of mental self‐rotation and other cognitive information processing. Mental self‐rotation is a process of rotating an embodied representational self through mental simulation of the sensorimotor mechanisms underlying actual self‐movement. It was predicted that physical development would affect the operation of the representational self. One hundred and twenty‐five individuals aged 5–80 years (57 children, 35 students, and 33 elderly people) executed a video game task of spatial perspective taking in three conditions of sensorimotor activation: A restrained, stable, and unstable condition. In the linear function formulas considering the degree of rotation and response times, the gradient represented the theoretical speed of mental self‐rotation and the intercept represented other cognitive processing. A significant interaction was found between age group and condition on the gradients, indicating that the response times in the unstable condition were faster than in the other conditions for the children, the restrained condition was slower than the other conditions for the students, while no difference was found for the elderly adults. The results suggest that the influence of sensorimotor activation on the embodied representational self depends on developmental changes in physical control.

独立型与依赖型自我：Markus等的自我结构研究

Markus认为不同的文化系统即个人主义与集体主义的文化将对应不同的自我结构：独立型自我和依赖型自我,而不同的自我结构可以解释预测个体在情绪、认知、动机等方面的差异。Markus等人的研究结果引人注目,同时也受到了相当多的质疑和批判。该文系统综述了这方面的情况。     

自我与有意遗忘现象

将自我参照效应的实验范式与字表方式的有意遗忘范式相结合,探讨有意遗忘在自我参照与他人参照条件下的异同。结果表明,在有意遗忘的研究范式下,自我参照加工和他人参照加工的回忆量之间不存在显著差异;但是自我参照条件下出现了有意遗忘现象,而他人参照加工条件下没有表现出有意遗忘现象。这表明,自我参照加工的材料,区辨性很高,因而有意遗忘的指导语激发的抑制作用对它有效,从而出现了遗忘现象。     

Reliability and validity of the self‐perception profile for adolescents: An Australian sample

In this study, we explored the psychometric properties and factorial validity of Harter's Self‐Perception Profile for Adolescents (SPPA) with an Australian sample drawn from the Raine study 14‐year follow‐up. Participants, boys (n = 795) and girls (n = 758) from Grades 8, 9, and 10, completed the SPPA. Cronbach's alpha showed good internal reliabilities for seven of the eight subscales and global self‐worth. Boys had significantly higher athletic (p < .001), physical appearance (p < .001), and romantic (p < .05) self‐perceptions, while the girls perceived significantly higher behavioural conduct (p < .001) and close friendships (p < .001). Exploratory factor analysis yielded similar factors to those reported by Harter with North American adolescents, although cross loadings resulted in one additional factor. Our findings generally supported Harter's conceptualisation of the self as a multidimensional construct, and with minor modifications, the use of the SPPA with Australian adolescents.
