From psychosocial equilibrium to catastrophic breakdown: Cyprus 1955–1974

The recent history of Cyprus presents an example of a society in which a centuries-long peaceful coexistence of diverse populations gave way to violence and murderous hate, with devastating end results. This paper tries to understand and describe the process by which Cypriot society slid from a position of psychosocial equilibrium and integration towards one of disintegration, fragmentation and catastrophic breakdown. This paper draws from work by social anthropologists, sociologists, historians and others, and from my own personal experience. To these I applied insights afforded by psychoanalysis to identify and explore the psychic processes and states of mind that characterized a psychosocial disintegrative process. I came to see external political events and internal psychological processes as inseparably intertwined and dynamically interdependent, each emanating from and catalysing the other. The factual details of the process described are of course unique in their local specificity, but the psychic phenomena that characterized it are not: at both the individual and group levels they are replicated in other societies undergoing similar processes of self-destruction.     

Children's sensitivity to circular explanations

The ability to evaluate the quality of explanations is an essential part of children's intellectual growth. Explanations can be faulty in structural ways such as when they are circular. A circular explanation reiterates the question as if it were an explanation rather than providing any new information. Two experiments (N=77) examined children's preferences when faced with circular and noncircular explanations. The results demonstrate that a preference for noncircular explanations is present, albeit in a fragile form, by 5 or 6 years of age and that it appears robustly by 10 years of age. Thus, the ability to evaluate the quality of explanations based on structural grounds appears to develop rapidly during the elementary school years.     

Social power and emotional experience: Actor and partner effects within dyadic interactions

A dyadic methodological and statistical approach to social power is used to test the notion that an individual’s power and a partner’s power have distinct effects on the individual’s emotional experience. Two studies examined actor and partner effects of social power on emotion within dyadic interactions. Across interpersonal contexts and measures of social power, the individual’s own social power, theorized to activate behavioral approach, was associated with positive emotion (an actor effect). In contrast, being subject to a partner’s elevated social power, theorized to activate behavioral inhibition, was associated with increased negative emotion (a partner effect). The discussion focuses on how dyadic methodological and statistical approaches point to new lines of inquiry in the study of social power.     

Longitudinal Changes in Intellectual Development in Children with Fragile X Syndrome

Structural equation modeling (SEM) was used to examine the development of intellectual functioning in 145 school-age pairs of siblings. Each pair included one child with Fragile X syndrome (FXS) and one unaffected sibling. All pairs of children were evaluated on the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) at time 1 and 80 pairs of children received a second evaluation at time 2 approximately 4 years later. Compared to their unaffected siblings, children with FXS obtained significantly lower percentage correct scores on all subtests of the WISC at both time points. During the time between the first and second assessments, the annual rate of intellectual development was approximately 2.2 times faster in the unaffected children compared to the children with FXS. Levels of the fragile X mental retardation protein (FMRP) were highly associated with intellectual ability scores of the children with FXS at both time points (r=0.55 and 0.64 respectively). However, when gender, age, and the time between assessments were included as covariates in the structural equation model, FMRP accounted for only 5% of the variance in intellectual ability scores at time 1 and 13% of the variance at time 2. The results of this study suggest that slower learning contributes to the low and declining standardized IQ scores observed in children with FXS.     

Behavioral and ERP measures of holistic face processing in a composite task

Holistic processing of faces is characterized by encoding of the face as a single stimulus. This study employed a composite face task to examine whether holistic processing varies when attention is restricted to the top as compared to the bottom half of the face, and whether evidence of holistic processing would be observed in event-related potentials. Analyses of behavioral data showed that spatial misalignment of the face halves disrupted holistic processing and enhanced detection of repeated attended halves. Effects of misalignment on the N170, VPP and N250 ERP components resembled effects of face inversion. Attention to the top half of the face was associated with faster P1, N170, VPP, and P2 latencies than attending to the bottom, suggesting automatic processing of the eye region. Further, N170 latency effects suggested that structural encoding of the face is facilitated during holistic processing. N250 latency effects reflected task difficulty. Finally, an overall right hemispheric asymmetry was most pronounced when holistic face processing was greatest. Results are discussed in light of recent proposals that holistic face processing is a subtype of configural face processing.     

Implicit emotional biases in decision making: the case of the Iowa Gambling Task

Many authors have endorsed the hypothesis that previous emotional experiences may exert a covert influence on behavior, but some findings and replications of the original studies challenged this view. We investigated this topic by carrying out an experiment with the Iowa Gambling Task (IGT), where a dissociation procedure was adopted to successfully isolate possible implicit components. After a typical interaction with the IGT, participants performed a "blind" card selection phase without receiving any feedback. Half of them were instructed to continue choosing as they did before, the other half was told that good card decks turned bad, and vice versa, so that explicit knowledge was necessary to overcome the previously learned deck-outcome associations. The results confirmed the existence of early acquired implicit biases, confirming that previously experienced emotional events may covertly affect subsequent behavior.     

Economic Disadvantage in Complex Family Systems: Expansion of Family Stress Models

Economic disadvantage is associated with multiple risks to early socioemotional development. This article reviews research regarding family stress frameworks to model the pathways from economic disadvantage to negative child outcomes via family processes. Future research in this area should expand definitions of family and household to incorporate diversity and instability. This expansion would be particularly relevant for research among low-income ethnic minority families and families with young children. This line of research would highlight specific pathways to target to prevent the onset of early parental and child dysfunction.     

不同条件下拟合指数的表现及临界值的选择

在本模拟研究中设计了6种样本容量,6种因子载荷,和4种评分等级,并考察了正态和非正态分布两种情况。采用的错误模型为参数误置（真模型中每个因子各由5个题目来测量,错误模型中则是第一个因子由6个题测量,另两个因子各由4个和5个题来测量,即有一个因子载荷被误置）模型。结果发现（1）样本量、载荷量、评分等级数和分布形态都对GOF的取值确有影响。其中分布形态的影响最大。NNFI、IFI在不同条件下的平均值是最稳定的,其次是CFI、RMSEA和SRMR。它们都算是值得推荐的GOF,尤其是NNFI和IFI。（2）在正态分布中,当样本量≥1000时,根据NNFI、IFI、CFI、RMSEA、SRMR对模型是否拟合做出判断时有很低的两类错误率,在样本量<1000时则不理想。在偏态条件下无论选择哪个GOF两类错误率都很高。（3）采用2指数策略在很多情况下也不能显著降低两类错误率。（4）由于在数据分布非正态,或正态但样本量<1000时是难判断模型是否拟合的。因此我们提出了2界值策略。即为每个GOF确定上下两个界值。低于下界值时可判断模型是不正确的,而高于上界值时则可判断模型是正确的。GOF取值处于上下界值之间时难以判断模型是否拟合,只能说越高拟合的可能性越大。这时就要通过跨样本验证和增加样本量来确定模型是否正确
