The Severity of Childhood Abuse and Neglect in Relationship to Post-Traumatic Stress Disorder Among Female Sex Workers in the Netherlands

In this article, the relationship between childhood abuse and neglect and post-traumatic stress disorder (PTSD) in adulthood is examined in a sample of 123 female indoor sex workers in the Netherlands. It was hypothesized that the severity of childhood abuse and neglect is associated with the severity of PTSD. In this study, a substantial number of sex workers had experienced abuse, neglect, or both during childhood. Furthermore, a substantial number suffered from PTSD. Results show significant differences between sex workers suffering from PTSD and sex workers not suffering from PTSD, in the extent to which they have experienced abuse or neglect. Logistic regression analysis shows emotional abuse contributes significantly to the prediction of PTSD. Our findings suggest that the high rate of PTSD among sex workers might be partially related to childhood experiences, indicating that a number of sex workers might be traumatized before entering sex work.     

The Simple Copy Task: Detecting Higher Order Visual Processing Deficits in Schizophrenia,Dementia, and Movement Disorder Groups

The Simple Copy Task (SCT) is a figure copying test with inherent appeal due to its short administration time, graded task difficulty, varied stimuli, and potential to eliminate floor effects. Despite this, there is a lack of data regarding its construct validity and diagnostic utility. The present study compared SCT performance of schizophrenia (n = 29), dementia (n = 64), and movement disorder (n = 12) groups with that of unmatched healthy control participants (n = 49). Movement disorder patients committed a high degree of misplacement errors, whereas dementia patients tended to omit items, add extraneous detail, and perseverate. The schizophrenia group was most similar to the dementia group in their performance on the SCT, committing primarily omission and perseveration errors. The SCT was most closely related to the Rey Complex Figure Task (r = 0.68, p < .01) and the Block Design Task (r = 0.62, p < .01). Age (r = ?0.14, p < .01) and education (r = 0.35, p < .01) effects were present; however, there was no impact of gender and handedness. Taken together, these findings provide support for the utility of the task and directions for clinical interpretation.     

Bimanual Training Reduces Spatial Interference

The authors investigated whether training can reduce bimanual directional interference by using a star-line drawing paradigm, Participants (N = 30) were required to perform rhythmical arm movements with identical temporal but differing directional demands. Moreover, the effectiveness of part-task training in which each movement was practiced in isolation was compared with that of whole-task training in which only combined movements were performed. Findings revealed that bimanual training substantially reduced spatial interference, but unimanual training did not. The authors therefore concluded that the spatial coupling of the limbs is not implemented in a rigid way; instead, the underlying neural correlate can undergo plastic changes induced by training. Moreover, the practical implication that emerged from the present study is that athletic, musical, or ergonomic skills that require a high degree of interlimb coordination are best served by whole-task practice.     

Scaling Estimates of Amplitude for Movements Without Visual Guidance

Three groups of subjects were involved in estimating movement amplitudes. Two of these groups used the method of estimation, labeling the amplitudes of simple linear movements in inches. One group made active movements, the other experienced passive movement of the arm. The third group, using the method of production, attempted to move the distance required by the experimenter’s label. Performance was described in terms of absolute, algebraic, and intrasubject variable error. No striking differences were noted between the three task groups, but males and females differed systematically. Females tended to over-estimate and males to underestimate the distances moved. Lack of evidence for any range effect suggests that subjects were operating from relatively stable perceptual traces, accessed by the verbal labels, rather than from memory traces of previous estimates of the same amplitudes.     

Child physical abuse and neglect in Kenya,Zambia and the Netherlands: A cross‐cultural comparison of prevalence,psychopathological sequelae and mediation by PTSS

This study compared the prevalence of self‐reported childhood physical abuse and neglect and the associated psychopathological sequelae among Kenyan, Zambian, and Dutch university students. In addition, we sought to find out the differentiated role of posttraumatic stress symptoms (PTSS) in mediating the associations between childhood maltreatment experiences and psychopathology symptoms. The sample consisted of 862 university students from Kenya (n = 375), Zambia (n = 182), and The Netherlands (n = 305) who completed the Personal and Relationships Profile (PRP). Results showed that physical abuse was highly prevalent in Kenya (59%) and Zambia (40%), and that neglect was even more prevalent than physical abuse in Zambia and The Netherlands at 59%, 54%, and 42% for the Kenyan, Zambian, and Dutch samples respectively. Neglect was associated with psychopathological symptoms in all three samples, whereas physical abuse was associated with psychopathological sequelae in the Kenyan and Zambian samples only. PTSS mediated the association between neglect and psychopathology symptoms in the Dutch sample and between physical abuse and psychopathology symptoms in the Dutch and Kenyan samples. We conclude that physical abuse and neglect are associated with psychopathology symptoms independently of country and cultural context. However, the pathways through which physical abuse and neglect may lead to psychopathological sequelae may be dependent on perceptions of specific parental behavior in different sociocultural contexts.     

儿童空间再定向能力发展的理论之争

空间再定向是指迷失方向的个体在空间中重新确定自己方位并找回迷失方向前丢失或被隐藏物体的能力.几何模块理论、适应性结合理论和视觉图像匹配理论都能够对儿童空间再定向做出一定解释,但三者之间互不相容,并存在局限:解释不了语言对整合几何和非几何信息的影响、环境空间大小和参照系选择对再定向的影响以及空间再定向中性别差异的现象.今后研究应注意实验的生态效应、空间条件的规则性、几何信息的直接性与间接性以及对三个理论的整合.     

空间偏向成因研究:理论解释与前景展望

空间偏向意指人们在注意刺激物时普遍具有方向上的偏好.对其成因,目前主要存在“大脑说”和“文化说”两派观点.前者认为大脑的不对称性是决定因素,而后者则认为阅读和书写习惯等文化因素是主要成因.本文在综述空间偏向研究后指出,以上两派学说在解释力上各有得失,但并非完全对立,将二者结合起来的“大脑-文化说”才能更好地解释空间偏向现象.     

Exploring the personal and social context of female youth sex offenders

This study explored the personal and social context of young female sex offenders, probing their risk profiles for prospective treatment interventions. A convenience sample of eight young South African female sexual offenders participated in the study (black = 88%, Indian = 12%, age range = 14–20 years). They completed semi-structured interviews on their perceptions of the influences to commit a sexual offence. The data were thematically analysed. Emergent themes on factors associated with sexual offending included: peer influence, poor child monitoring, parental neglect, unproductive sexual health education, as well as insight into the participants’ maladaptive beliefs and distorted thinking.
