Use of first person pronouns as a function of increased objective self-awareness and performance feedback

A recent integrating formalation in social psychology, the Duval-Wicklund theory of “objective self-awareness,” has the core assumption that attention focused on the self is always aversive and, hence, avoided. While faced with either a TV camera or a mirror, and after they had received false feedback concerning their creativity, 98 undergraduates guessed at the meaning of foreign language pronouns, the unobtrusive dependent measure of the direction of the focus of attention. The standard Duval-Wicklund effect was replicated—more attention to self, that is, more first-person pronouns—in the “camera” or “mirror” than in the “no camera” or “no mirror” conditions. However, within the camera or mirror conditions, avoidance of self-focused attention occurred only after negative feedback.     

Sex and sociability in rats

Three experiments explored the effects of sexual motivation and the opportunity for sexual contact on social attraction in rats. Rats were no more gregarious in cross-sex than in same-sex pairings. Increased male sexual experience and hormonally induced female receptivity both led to increased sexual activity but had no effect on social behavior. Males housed with continuously receptive females showed signs of sexual exhaustion but were as gregarious as males housed alone or with males. It appears that social attraction in rats is not motivated primarily by sexual desires, either direct or sublimated.     

Comprehension of symbolic gestures in aphasia

One-hundred-and-twenty-eight patients with unilateral hemispheric damage (53 aphasics, 26 nonaphasic left, and 49 right brain-damaged patients) and 25 normal controls were given a test of symbolic gesture comprehension and other tests of verbal comprehension and of reproduction of symbolic gestures. On the test of symbolic gesture interpretation aphasic patients performed significantly worse than any other group of brain-damaged patients. Within the aphasic patients the inability to understand the meaning of symbolic gestures was highly related to the number of semantic errors obtained at a verbal comprehension test. On the contrary, only a mild relationship was found between comprehension and reproduction of symbolic gestures. Some implications of these findings are discussed.     

The development of alertness

Two experiments explored variation in the alerting process across age and warning interval as well as the effects of alertness on subsequent processing. Experiment 1 obtained alertness functions for a group of 5-year-olds, 8-year-olds, and adults. Results revealed strong age differences in speed of alerting and in maintenance of alertness over a 1-sec interval. Five-year-olds alerted more slowly than older groups and sustained optimal alertness less well. Both groups of children showed more variability in alerting functions compared with adults. Experiment 2 examined the degree to which age differences in processing speed were attributable to differential speed and maintenance of alerting. Masking functions obtained across variations in the alerting interval revealed that when level of alertness was optimal in both 5-year-olds and adults, minimal age differences in processing speed were observed. During short, nonoptimal alerting intervals, speed of processing in adults was faster than in 5-year-old children. The pattern of results across studies suggested that alertness can fluctuate over time in young children, that level of alertness affects subsequent perceptual processing speed, and that developmental variation in speed and maintenance of alertness can partly explain observed age differences in processing speed. The potential role of alertness in more complex cognitive tasks is discussed.     

The development of spatial understanding in infancy

This paper examines the development of spatial understanding between 8 and 24 months. In particular, it examines whether young infants code changes in the position of an object or themselves in geographic or egocentric terms. The infants sat in a baby chair which was attached to a circular table in such a way that either the infant could be rotated around the edge of the table or the table-top itself could be rotated. Rotation of infant or table could be performed independently or simultaneously. Infants were shown an object which was then hidden under one of either two or three identical cups sitting on the table. Before the infant was allowed to search for the toy, either the table, the infant, or both were rotated, a procedure which resulted in an invisible displacement of the object in terms of geographical and/or egocentric spatial position. Rotations of 60, 90, 120, and 180° were used. Three groups of infants were tested, one cross-sectional (12–24 months), one longitudinal (12–24 months), and one consisting of a group of infants already known to be accelerated in object concept development (8–20 months). The cross-sectional results indicated that egocentric responding continues well into the second half of the second year of life. Even with fortnightly exposure to the tasks, egocentric responding was still evident in some longitudinal babies as late as 19 months. The results of the accelerated group suggest that acceleration through the sequence of object concept development facilitates development of spatial understanding in a wider sense, that is, in the sense of understanding the interrelation of positions in space. The implications of these results for competing theories of the source of object concept errors are discussed.     

Deep dyslexia, imageability, and ease of predication

A development of existing theories of deep dyslexia is outlined. It proposes that the effects of imageability upon the ease of reading of words by deep dyslexics occur as a result of variation in the ease with which individual words summon semantic predicates, on the basis of which reading responses can be made. Ease-of-predication scores are obtained for a corpus of nouns and found to be, as hypothesized, closely related to imageability scores. It is shown that the other major characteristics of deep dyslexia can also be accounted for by this proposed mechanism. These include the well-established effects of syntactic category (in particular, of the distinction between content and function words) upon reading. Further evidence is provided that this effect may be attributed to variation in ease of predication.     

父母忽视与青少年网络游戏成瘾的关系:希望的中介作用和性别的调节作用

为探究父母忽视与青少年网络游戏成瘾的关系及其中心理机制,本研究以全国七个省的八所中学共805名初二学生为被试,采用问卷法考察了父母忽视与青少年网络游戏成瘾的关系及希望在其中的中介作用,并检验了该过程是否受到性别的调节。在控制了每周上网时间和网龄后,结果发现：（1）父母忽视对网络游戏成瘾具有正向预测作用;（2）希望在父母忽视和网络游戏成瘾间起到完全中介作用;（3）性别调节了中介模型的前半段路径,具体表现为相对于女生,父母忽视对男生希望的负向预测作用更显著。结果表明父母忽视会明显降低初二学生的希望水平,进而增加其网络游戏成瘾风险,并且在男生群体中的作用更加显著。     

The Moral Argument for the Existence of God and Immortality

This essay tries to show that there exist several passages where Kierkegaard (and his pseudonyms) sketches an argument for the existence of God and immortality that is remarkably similar to Kant's so‐called moral argument for the existence of God and immortality. In particular, Kierkegaard appears to follow Kant's moral argument both when it comes to the form and content of the argument as well as some of its terminology. The essay concludes that several passages in Kierkegaard overlap significantly with Kant's moral argument, although Kierkegaard ultimately favors revealed faith over natural theology in general and Kant's moral faith in particular. Whereas Kant uses the moral argument to postulate the existence of God and immortality, Kierkegaard mainly uses it as a reductio ad absurdum of non‐religious thinking.
