NOTE ON THE RETENTION OF CONNECTED DISCOURSE

Two sentences were constructed having roughly the same content but different predictability ( P -) scores. One or other of the sentences was presented auditorily once only to different groups of subjects who were instructed to listen carefully, without however, being informed of the learning character of the experiment. The groups were then tested for retention after one of the following intervals: IM, 3 min., 2 hours, 20 hours. The sentences were found to differ in memorability (amount recalled) in IM but not in LTM. The reproductions were also analysed with regard to synonym and non-synonym substitutions and the implications for the chunking hypothesis discussed.     

Gender and projective imagination of threat in achievement and affiliation situations

In a study by Pollak and Gilligan (1982) where fantasies of violence were seen as indicative of perception of danger, women responded with more violent imagery to situations of achievement, whereas men responded with more violent imagery to affiliation situations. This indicates gender differences in motivational needs, which corresponds to modern gender development theories (e.g., Chodorow, 1978). In the present studies, the hypotheses that women fear achievement situations whereas men fear situations of affiliation were tested on Swedish samples totaling 44 men and 47 women. In Study 1, the hypothesis that violent imagery correlates with affiliation themes in the stories written by men was partly supported, whereas the hypothesis that violent imagery would be highly correlated with achievement themes in the stories written by women was not confirmed. In Study 2, no support was obtained for the hypotheses. In sum, contrary to previous studies, no substantial support was obtained for the hypothesis that women connect violent imagery with achievement situations, whereas some evidence was found for the hypothesis that men construe danger as arising from affiliation situations. The greater incidence of violence in men’s fantasy reported in previous studies was not supported in either of the two studies. The results are discussed in the context of cross-cultural differences.     

A COMPARATIVE STUDY OF SOME MULTIDIMENSIONAL VECTOR MODELS FOR SUBJECTIVE SIMILARITY

E kehammar B. A comparative study of some multidimensional vector models for subjective similarity. Scand. J. Psychol ., 1972, 1 3 , 190–197.—h this report, two theoretical vector models for subjective similarity were deduced from a "content" definition of subjective similarity. One of the derived similarity equations proved in empirical model testing to describe the similarity principle in perception of form better than earlier, similar models. Deviations between observed similarity estimates and values expected according to the model are discussed, among other things, in terms of the heterogeneity of the stimulus set.     

Against Disjunctive Properties: Four Armstrongian Arguments

Philosophia - This paper defends the case against (sparse) disjunctive properties by means of four Armstrongian arguments. The first of these is a logical atomist argument from truthmaking, which...     

消除威胁或无能狂怒?自恋对暴力犯攻击的影响机制

通过2个研究探索了自恋与暴力犯攻击行为的关系及机制。研究1通过问卷法(N = 498)发现, 自恋与攻击存在正相关, 特质愤怒在自恋与预谋性和冲动性攻击间的中介作用成立, 心理特权的中介作用只对预谋性攻击成立。研究2对90名暴力犯进行了行为学实验, 结果表明威胁感和负性情绪在自恋与攻击间起中介作用, 挑衅调节了上述中介作用。显性自恋者只在挑衅条件下表现出更强的攻击性, 隐性自恋者则在挑衅和无挑衅条件下均有较强的攻击性。研究厘清了不同亚型下自恋与攻击的关系, 突出了隐性自恋的“黑暗性”, 并为罪犯矫治管理及犯罪预防提供了参考。     

Egocentric Distance Perception Disorder in Amblyopia

Egocentric distance perception is a psychological process in which observers use various depth cues to estimate the distance between a target and themselves. The impairment of basic visual function and treatment of amblyopia have been well documented. However, the disorder of egocentric distance perception of amblyopes is poorly understood. In this review, we describe the cognitive mechanism of egocentric distance perception, and then, we focus on empirical evidence for disorders in egocentric distance perception for amblyopes in the whole visual space. In the personal space (within 2 m), it is difficult for amblyopes to show normal hand-eye coordination; in the action space (within 2 m~30 m), amblyopes cannot accurately judge the distance of a target suspended in the air. Few studies have focused on the performance of amblyopes in the vista space (more than 30 m). Finally, five critical topics for future research are discussed: 1) it is necessary to systematically explore the mechanism of egocentric distance perception in all three spaces; 2) the laws of egocentric distance perception in moving objects for amblyopes should be explored; and 3) the comparison of three subtypes of amblyopia is still insufficient; 4) study the perception of distance under another theoretical framework; 5) explore the mechanisms of amblyopia by Virtual Reality.     

Checking EMTLK Properties of Timed Interpreted Systems Via Bounded Model Checking

We investigate a SAT-based bounded model checking (BMC) method for EMTLK (the existential fragment of the metric temporal logic with knowledge) that is interpreted over timed models generated by timed interpreted systems. In particular, we translate the existential model checking problem for EMTLK to the existential model checking problem for a variant of linear temporal logic (called HLTLK), and we provide a SAT-based BMC technique for HLTLK. We evaluated the performance of our BMC by means of a variant of a timed generic pipeline paradigm scenario and a timed train controller system.     

Investigation of tensile deformation mechanisms at room temperature in a new Ni-based single crystal superalloy

The deformation microstructures of a new Ni-based single crystal superalloy, M 4706, have been characterized by transmission electron microscopy after interrupted tensile tests at room temperature. It is found that besides shearing of γ′ precipitates by strongly coupled dislocations, another unusual shearing process involving a single a/2 〈1?0?1〉 matrix dislocation as well as the formation of the isolated superlattice stacking fault and Shockley loop also operates actively during initial yielding. Based on experimental observations, occurrence of these different shearing processes is discussed.     

Parent and Family Characteristics and Their Associates in a Follow-Up of Outpatient Children with ADHD

We examined associations between child symptoms, demographic variables, parent and family characteristics in a long-term follow-up study of 214 outpatient children with attention-deficit/hyperactivity disorder (ADHD). The children’s mean age was 12.6 (SD = 2.1) years, and the mean interval from diagnosis to follow-up was 3.7 (SD = 2.2) years. We compared the characteristics of the clinical group with a community group (n = 110) recruited from the same catchment area. Parents filled out questionnaires on child symptoms, parent characteristics, and family functioning. The results showed that parents of young boys (<13 years) experienced more parenting stressors than those of adolescent boys (≥13 years), but the opposite was true for parents of girls. Parents of children with both ADHD and oppositional defiant disorder symptoms in the clinical range experienced significantly more parent and family dysfunctions than those of children with ADHD only (even after controlling for levels of ADHD symptoms in the child). Parents of children in the community group experienced significantly less parent and family dysfunctions than those of children with ADHD. Partial correlations between parent characteristics and child symptoms showed that oppositional symptoms were most strongly associated with parent and family dysfunction. Fathers experienced significantly less parenting stress, parental efficacy, and child involvement than mothers. We conclude that parents of children with ADHD experienced considerable strain related to a broad range of parent and family characteristics. Assessment of such characteristics should be part of routine assessment procedures and a prerequisite for family-focused treatment of children with ADHD.     

基于通道的内源性注意对声音诱发闪光错觉的影响

声音诱发闪光错觉是指当视觉闪光伴随不相等数量的听觉声音在100 ms内相继或同时呈现时, 个体会错觉性地知觉到视觉闪光的个数与听觉声音的数量相等。研究采用经典的声音诱发闪光错觉范式, 将注意以内源性的方式指向视觉通道或者听觉通道, 考察了基于通道的内源性注意对声音诱发闪光错觉的影响。结果发现, 当注意内源性地指向视觉通道时, 相对于基线条件, 裂变错觉的量显著减小; 当注意内源性地指向听觉通道时, 相对于基线条件, 裂变错觉的量存在增大的趋势。说明了基于通道的内源性注意可以影响声音诱发闪光错觉中的裂变错觉, 但不影响融合错觉。
