This paper describes some features of the behaviour of a severely disturbed adopted latency boy. Peter was born premature, suffered several early hospitalizations and surgical operations, and at 2 months of age was removed from his mother's care by Social Services for neglect and abandonment.
Although his subsequent development has been clouded by a series of losses and sudden changes of caregivers, Peter has maintained an unexpected desire to relate, showing considerable innate resilience. When feeling endangered, Peter had developed a defensive olfactive container using his bodily smell and farts to envelop himself in a protective cloud of familiarity against the dread of falling apart, and to hold his personality together.
In the paper Fordham's views of development and Anzieu's concept of psychic envelopes constitute the theoretical underpinning. Bion's concepts of beta- and alpha-elements are discussed in relation to Jung's views on symbolic development and psychological containment.  相似文献

In Experiment 1 six hungry gerbils received six trials per day on a 17-arm radial maze. During each trial the subjects were allowed to choose freely among the arms, each of which contained a food pellet, until each arm had been visited once or until eight minutes had elapsed. An error was recorded when the subject entered a previously visited arm. The gerbils quickly learned not to re-enter previously visited arms and generally made errors on fewer than 15% of entries, performance comparable to that of the rat and superior to that of other species tested in the radial arm maze. The intertrial-interval duration did not affect accuracy of arm choices during acquisition but did influence asymptotic accuracy. Accuracy did not change systematically over the six trials. A high proportion of arm entries were to nearby arms. Errors occurred most often towards the end of a trial. Odor cues were not important. When the number of trials per day was reduced from six to one, accuracy deteriorated slightly. In Experiment 2 neither the transposition of extramaze cues nor the placement of the maze in a different room had large disruptive effects on accuracy. In Experiment 3 the addition of three explicit intramaze brightness cues aided accuracy, perhaps by permitting the subjects to decompose the large maze into three smaller mazes, although there was no direct evidence that this was the case. Implications of a number of these results for models of spatial maze performance were discussed.  相似文献

Naturalistic observational techniques were employed over a four-week period to assess the behavior of clinically improved (n=7) and unimproved (n=12) hospitalized patients suffering from acute psychiatric disorders. The population was selected from four clinical diagnostic groups. Patients were sampled on an individual basis. Categories of recorded behaviors included social behavior as well as spatial proximity measures between individuals. Social behavior was further divided into components of sending and receiving. Results showed that patients who clinically improved had significantly different behavioral profiles and greater degrees of behavioral change for the following categories: send affiliation, receive affiliation, send assertion, and receive assertion. Improved patients also maintained closer distance to other individuals during the latter stages of hospitalization. In most cases, week 2 of hospitalization marked the point at which behavioral divergence between improved and unimproved patients occurred. Clinical and theoretical implications of observational procedures are discussed.  相似文献

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。  相似文献

语言的获得会对空间认知产生深刻的影响。关于语言与空间认知,近些年来,不仅有大量的相关研究发现语言能力跟空间认知能力之间存在着密切的关联,还出现了实验研究,来试图直接揭示语言对空间关系表征的影响。研究发现,在一系列涉及不同空间关系的任务中,相较于非语言线索,语言线索提示的效果明显更好。在此基础上,从语言编码的特点和加工过程等方面进一步分析语言的作用机制,发现在空间表征中语言主要起到了选择和整合的作用,语言的作用过程是即时性的。建议未来研究在空间任务和语言表述形式上有更多的变式,从而更全面地来揭示语言的作用。  相似文献

The hippocampus is closely tied to spatial navigation, a central component in cognitive functioning, and critically involved in age-associated cognitive decline and dementia. This study evaluated a novel, cognitive computerized spatial navigation training (CSNT) program targeting the hippocampus, with expectation of mitigating possible cognitive decline with bed rest (BR). During a 14-day BR study with 16 healthy, older men (mean age = 60 ± 3, range = 55–65 years), half received CSNT for 12 days in 50-min sessions and half were controls (watching documentaries). This design uniquely controlled diet, sleep, and other personal and environmental activities. Although there were no cognitive declines in controls post-BR, CSNT participants demonstrated significant increases in executive/attention ability and processing speed, and continued spatial navigation testing showed improvement to 400 days post-BR. This intervention may prove useful to mitigate cognitive declines known to occur in long periods of immobilization and could have broader implications in protecting against age-related cognitive decline.  相似文献

We study the semantic relationship between pairs of nouns of concrete objects such as “HORSE - SHEEP” and “SWING - MELON” and how this relationship activity is reflected in EEG signals. We collected 18 sets of EEG records; each set containing 150 events of stimulation. In this work we focus on feature extraction algorithms. Particularly, we highlight Common Spatial Pattern (CSP) as a method of feature extraction. Based on these latter, different classifiers were trained in order to associate a set of signals to a previously learned human answer, pertaining to two classes: semantically related, or not semantically related. The results of classification accuracy were evaluated comparing with other four methods of feature extraction, and using classification algorithms from five different families. In all cases, classification accuracy was benefited from using CSP instead of FDTW, LPC, PCA or ICA for feature extraction. Particularly with the combination CSP-Naïve Bayes we obtained the best average precision of 84.63%.  相似文献

Despite the increase in the use of interactive technological devices, little is known about the impact that play context has on the production of spatial language by parents. To investigate whether there is differential parental spatial input afforded by play contexts with their preschoolers, 34 children (20 girls, 14 boys) and their primary caregivers engaged in 30‐min 3‐dimensional (3D) spatial play using blocks and puzzles and virtual 2‐dimensional (2D) spatial play using an iPad® in 2 separate home visits. There were no significant differences in the average amount of spatial talk and the number of spatial categories used by parents in both 3D and 2D play contexts. However, the amount of parental spatial talk decreased significantly with older preschoolers using the iPad®. In the 3D play contexts, parents produced more words related to spatial dimensions, location and directions, and continuous amount than in the 2D play contexts. However, in the 2D play contexts, they produced more words associated with orientations and transformations as well as deictics than in the 3D play contexts. Our findings suggest that technology can be effectively introduced into play contexts to elicit enriched parental spatial input by supporting parents and caregivers with best practices.

Highlights

  • The present study examines the differences in parental spatial talk when using traditional versus technology‐based learning tools with their preschoolers.
  • Two 30‐min home observations of parent–child dyads playing blocks and puzzles versus spatial apps on an iPad®. No significant differences in the amount of parental spatial talk and the number of spatial categories in both play contexts were found.
  • Our findings suggest that technology can be effectively introduced into play contexts to elicit enriched parental spatial input.
