男性择偶策略改变的前提：自感配偶价值提高

研究分为问卷调查与实验研究两部分。首先,40名女性和33名男性完成有关自感配偶价值评价（SPMV）和择偶偏爱策略的问卷调查,问卷调查结果是实验研究中数据分析的基线。其次,第二部分实验开始后,被试会得到实验者编造的他人潜在择偶对象的积极正面评价,其目的在于提高被试的SPMV。可以假设,男性的SPMV与随意性行为的认同或追求有正相关,男性SPMV的提高将会更加偏爱短期的性策略;女性SPMV与随意性行为不存在相关,女性SPMV的提高不会改变女性的性策略。研究结果显示,SPMV高基线水平的男性更加认可随意性行为,男性SPMV的提高与短期策略选择的增加有关。另外,SPMV提高,而不是一般自尊的提高,与择偶策略的改变具有相关。本研究结果没有证实,与长期稳定的性关系相比,SPMV的基线水平或是提高与女性对随意性行为的认同或追求之间存在相关     

人类“性交往”的进化

性交往是人类繁衍出现差异的进化“引擎”。现代人继承了祖先成功繁衍后代的性交往策略。这些策略涵盖长期守诺的性交往（如婚姻）、短期性交往（如短暂的外遇）、婚姻外的性交往（如不忠）、私通他人配偶（引诱别人的配偶）以及配偶维持（与单一配偶性交往）等。两性在性交往过程中面临不同的适应问题,性交往问题的进化机制存在极大的性别差异。配偶偏好不同、短期性交往的愿望不同以及性嫉妒的诱因不同等都是性交往具有性别差异的表现。很多实证研究都证实了性交往策略的存在,人类性交往研究是进化心理学研究中较为成熟的一个研究领域     

进化发展心理学：发展中的人类本性

进化发展心理学研究社会能力与认知能力发展背后的基因与环境机制,以及基因与环境机制在特定社会文化中的表现。进化发展心理学探讨的主要问题与设计到的主要概念包括：（1）自然选择在毕生发展的早期阶段发挥作用;（2）进化发展心理学特别重视适应在婴儿期及儿童期发展中的作用;（3）儿童期的延长有助于儿童学习人类社会的复杂性;（4）发展背景的方法可以用来理解成人外显行为的进化起源;（5）基因与环境因素相互影响约束个体发展;（6）认知能力与行为活动敏感于早期环境,但二者发展也具有可塑性     

A developmental approach to violence, hostile attributions, and paranoid thinking in adolescence

Research within the area of paranoid thinking has focused primarily on adults and has only recently looked at the effects during the critical life stage of adolescence, with even less research in the context of the juvenile justice system. This article aims to explore the relationship between antisocial behaviour in adolescence and the development of paranoid thinking, set within wider contexts that surround the juvenile justice system. The information presented is drawn from both the current research and the clinical experiences of those working in adolescent forensic psychiatry services. The relationships with other disorders such as conduct disorder, ADHD, PTSD, and depression are also explored.     

Naming of grammatical classes in frontotemporal dementias: linguistic and non linguistic factors contribute to noun-verb dissociation

We studied noun and verb naming in three main variants of frontotemporal dementia: the frontal variant(Fv-FTD), primary progressive aphasia (PPA) and semantic dementia (SD). We further distinguished PPA in nonfluent and fluent forms and restricted diagnosis of SD to subjects with progressive semantic breakdown leading to agnosia for words and objects. Fv-FTD and nonfluent-PPA named objects better than actions, SD showed an inverse dissociation and no specific pattern emerged in fluent-PPA. In this last group, in spite of the broad definition of fluent aphasia, quite heterogeneous patterns of language disorders and word class dissociation emerged when single-subject analyses were performed. In fv-FTD correlations between executive tasks and action naming were stronger than between executive tasks and object naming. We conclude that both linguistic and non linguistic factors, in particular an executive deficit, contribute to grammatical class dissociation. We also suggest that the fluent vs. nonfluent distinction does not reflect the complexity of primary aphasia.     

Personality change at the intersection of autonomic arousal and stress

We hypothesized that personality change in children can be predicted by the interaction of family risk with susceptibility to autonomic arousal and that children characterized by both high-risk families and highly reactive autonomic nervous systems tend to show maladaptive change. This hypothesis was tested in a 6-year longitudinal study in which personality-type prototypicality, problem behavior, and negative emotional intensity were measured at 2-year intervals. The results indicated that children who both had exaggerated skin conductance responses (a measure of autonomic reactivity) and were living in families with multiple risk factors were most likely to develop an undercontrolled personality type and to exhibit increases in problem behavior and negative emotional intensity. The implications of the results for understanding personality change are discussed.     

The generation effect in monkeys

How well one retains new information depends on how actively it is processed during learning. Active attempts to retrieve information from memory result in more learning than passive observation of the same information (the generation effect). Here, we present evidence for the generation effect in monkeys. Subjects were trained to respond to five-item lists of photographs in a particular order. On some lists, they could request "hints" to guide their behavior; on others, they had to generate the correct order from memory. Training with hints resulted in high levels of initial performance, but accuracy dropped precipitously when the hints were removed on the criterion test. Training without hints led to relatively poor initial performance, but accuracy increased steadily and remained high on the criterion test.     

Sleep-associated changes in the mental representation of spoken words

The integration of a newly learned spoken word form with existing knowledge in the mental lexicon is characterized by the word form's ability to compete with similar-sounding entries during auditory word recognition. Here we show that although the mere acquisition of a spoken form is swift, its engagement in lexical competition requires an incubation-like period that is crucially associated with sleep. Words learned at 8 p.m. do not induce (inhibitory) competition effects immediately, but do so after a 12-hr interval including a night's sleep, and continue to induce such effects after 24 hr. In contrast, words learned at 8 a.m. do not show such effects immediately or after 12 hr of wakefulness, but show the effects only after 24 hr, after sleep has occurred. This time-course dissociation is best accommodated by connectionist and neural models of learning in which sleep provides an opportunity for hippocampal information to be fed into long-term neocortical memory.     

Effects of decompressive surgery on prognosis and cognitive deficits in herpes simplex encephalitis

Herpes simplex encephalitis (HSE) is a serious viral infection with a high rate of mortality. The most commonly seen complications are behavioral changes, seizures and memory deficits. We report the case of a 37-year-old man with HSE in the right temporal lobe and a severe midline shift who was treated with acyclovir. The patient underwent anterior temporal lobe resection. Although HSE can cause permanent cognitive deficits, in this case, early surgical intervention minimized any deficit, as determined by detailed neuropsychological examination. Surgical decompression is indicated as early as possible in severe cases. This case report emphasizes the effect of surgical decompression for HSE on cognitive function, which has rarely been mentioned before.     

Recognition of facial expressions of different emotional intensities in patients with frontotemporal lobar degeneration

Behavioural problems are a key feature of frontotemporal lobar degeneration (FTLD). Also, FTLD patients show impairments in emotion processing. Specifically, the perception of negative emotional facial expressions is affected. Generally, however, negative emotional expressions are regarded as more difficult to recognize than positive ones, which thus may have been a confounding factor in previous studies. Also, ceiling effects are often present on emotion recognition tasks using full-blown emotional facial expressions. In the present study with FTLD patients, we examined the perception of sadness, anger, fear, happiness, surprise and disgust at different emotional intensities on morphed facial expressions to take task difficulty into account. Results showed that our FTLD patients were specifically impaired at the recognition of the emotion anger. Also, the patients performed worse than the controls on recognition of surprise, but performed at control levels on disgust, happiness, sadness and fear. These findings corroborate and extend previous results showing deficits in emotion perception in FTLD.
