Genetic and Environmental Influences on the Development and Stability of Executive Functions in Children of Preschool Age: A Longitudinal Study of Japanese Twins

Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is important to consider genetic variations when investigating environmental influences on EF development in children. To date, few studies have used genetically informative designs to assess the etiology of EF development during the preschool years, a period of rapid development. As a result, it remains unclear how and to what extent the environmental influences that are not confounded by genetic influences affect EF development during this developmental period. The present study explored EF development during the preschool years using a longitudinal and genetically informative design and a non‐Western population. Japanese twins were visited at their homes and individually tested on EF measures at 24, 36, and 48 months of age. Phenotypic correlations and confirmatory factor analyses suggested that EF are less cohesive at 24 months of age and emerge as a common single factor at 36 and 48 months. Additionally, longitudinal and multivariate behavioural genetic analyses indicated that the EF developmental change during this period is promoted by both shared and nonshared environmental influences as well as genetic influences, while EF stability is brought about by shared environments. The present findings elucidated the etiology of EF development during the preschool years and confirmed that this period is an important transitional stage for EF development.

Hierarchisation and dominance assessment at first glance

In this study 97 subjects were observed during free discussions in same sex triads and dyads. In earlier research, it has been found that rank-ordering in ad hoc groups occurs at a very early phase of the interaction. In this study it is shown that, in the absence of status characteristics, rank-ordering occurs not only right from the beginning of group interactions, but even exists after a first glance, before one word has been spoken. Not only nonverbal behaviours that are usually associated with the development or maintenance of a dominance position appear to be predictive for the amount of talking in the discussion to follow, but also personality measures. As the verbal interactions do not result in a change of the first glance rank-ordering, our data support the view that rapid judgements of interpersonal relationships may occur without much cognitive information processing.     

Environmental Refugees: What Rights? Which Duties?

It is estimated that there could be 200 million‘environmental refugees’ by the middle of this century. One major environmental cause of population displacement is likely to be global climate change. As the situation is likely to become more pressing, it is vital to consider now the rights of environmental refugees and the duties of the rest of the world. However, this is not an issue that has been addressed in mainstream theories of global justice. This paper considers the potential of two leading liberal theories of international justice to address the particular issues raised by the plight of potential and actual environmental refugees. I argue that neither John Rawls’s ‘Law of Peoples’ approach nor Charles Beitz’s `cosmopolitanism' is capable of providing an adequate account of justice in this context. Beitz’s theory does have some advantages over Rawls’s approach but it fails to take proper account of the attachment that some people have to their own ‘home’.

Reevaluating the Identity Status Paradigm: Still Useful after 35 Years

In this article we respond to van Hoof's (1999) critique of the identity status paradigm. Our review and evaluation of the existing data on identity statuses lead us to be more optimistic than van Hoof about the convergent and discriminant validity of identity status measures, especially objective measures that provide continuous status scores as well as nominal status classifications. Our review of longitudinal studies revealed that among university students tested annually 3 or more times, change in status classifications is significantly more likely to be observed than stability. Moreover, virtually all longitudinal studies with university students indicate that status changes are more likely to be progressive rather than regressive in terms of the hypothesized identity status developmental sequence. However, considerable status regression and fluctuation is observed and we agree with van Hoof that it may no longer be useful to postulate an invariant sequence of identity status stages. Nonetheless, the data do indicate reliable status differences in self-regulatory control processes including ego development, social-cognitive processing orientations, cognitive complexity, self-integration, moral development, and so on. Consequently, we conclude that a useful strategy, at least with university students, may be to focus on the social-cognitive processes that underpin identity statuses and to conceptualize these identity orientations as different styles of dealing with the demands, challenges, and opportunities afforded by institutionalized moratoria, such as a university context. Two lines of recent research inspired by this conceptualization are discussed.     

ASPIRing to Mitigate Climate Change: Superordinate Identity in Global Climate Negotiations

The issues surrounding rising levels of atmospheric CO₂ and climate change have become part of the collective conscious and the vernacular of world leaders, media, and the public alike. Despite the widespread concern and attention, attempts to achieve a global commitment to mitigate climate change are failing. In this article, we suggest that the Actualizing Social and Personal Identity Resources model (ASPIRe; Haslam, Eggins, & Reynolds, 2003 ), developed to help organizations become more sustainable and productive, can promote more efficient negotiations in matters of global environmental concern. Using this model as a framework, the dynamics of the United Nations (UN) meeting in Copenhagen are scrutinized along with suggestions for how to structure future negotiations. Building on an understanding of existing UN‐type committee structures, it is argued that as the interests of individual nations and those of like‐minded other nations (subgroup interests) become the real basis for decision making on the issue of climate change the more likely it is that a higher‐order superordinate identity will emerge, which promotes aligned action. To date, the psychological aspects of social and behavioral change have been neglected, which could be a factor in explaining the lack of coordinated action on climate change.     

Implementing climate equity: the case of Europe

For over two decades, international environmental equity – the fair and just sharing of the burdens associated with environmental changes – has been the subject of much debate by philosophers, activists and diplomats concerned about climate change. It has been manifested in many international environmental agreements, notably the Framework Convention on Climate Change and the Kyoto Protocol. The question arises as to whether it is being put into practice in this context. Are the requirements of international environmental equity merely words and principles in international instruments, or are they having a practical effect on the policies of state governments? This article aims to start answering these questions. It examines whether the European Union (EU) and its member states are sharing the burdens of climate change. The article introduces equity in the context of the climate change agreements and looks at some normative and practical considerations. It suggests that Europe has been a leader on international equity in the climate change negotiations over the last decade, and it points to what European states and the EU have done to take on some of the burdens of climate change. Europe's actions are briefly assessed from practical and normative perspectives. Europe is doing more than any other part of the world to address climate change and to share the burdens associated with it. Nevertheless, Europe is not doing as much to address this problem as it can and should do. Both practical and normative imperatives demand more urgent action by Europe to implement climate equity.     

In the Midst of Multiplicity: How to Stay in the Saddle

The author asks the question, how is the human psyche impacted by the current rapid cultural change, globalization, etc., that is presently occurring in our world. She describes the relationship between the horse and the rider as an amplification of the relationship between the psyche and the ego in coping with change. How does one build a good relationship? In times of confusion and rapid change, the horse will likely panic and throw the rider if there is a poor relationship between them. She describes some of the clients in therapeutic riding centers, particularly the more vulnerable teenage clients, as being “unhorsed”—disconnected from their positive instincts—and how this form of therapy is particularly helpful because it reconnects them with their “inner horse.” She describes how she learned to develop a bonded relationship with her own horse and how that kind of relationship can operate within a context of the cutting horse competition.     

Human Response to Environmental Changes

A range of factors affect human response to environmental change. They include the information available, understanding of the phenomenon, the nature of the decision-making processes implied, and the motivation for change. One major factor affecting decision making is that scientific information is not fully and accurately disseminated through society. The media have an important role in this process, but cannot disseminate all the necessary information in the manner that is required and do not reliably present information that is safe from misinterpretation. Further, scientific uncertainty about and complexity of biosphere changes complicate the process of reaching a rational decision. The mental model that people have of their world tends to be maintained unless it is contradicted by experienced events, so global change is likely to be understood only to the extent that it impacts on everyday life. Much of human reasoning is essentially analogical rather than based on standard logic, and its validity depends on finding a suitable analogical model. It is suggested that risk, or defence situations may provide useful analogies. Finally, we need to consider the motivational problems created by the sacrifices that must be made to deal with the problem effectively.     

The use of operant technology to measure behavioral priorities in captive animals

Addressing the behavioral priorities of captive animals and the development of practical, objective measures of the value of environmental resources is a principal objective of animal welfare science. In theory, consumer demand approaches derivedfrom human microeconomics should provide validmeasures of the value of environmental resources. In practice, however, a number of empirical and theoretical problems have rendered these measures difficult to interpret in studies with animals. A common approach has been to impose a cost on access to resources and to use time with each resource as a measure of consumption to construct demand curves. This can be recorded easily by automatic means, but in a number of studies, it has been found that animals compensate for increased cost of access with longer visit time. Furthermore, direct observation of the test animals’ behavior has shown that resource interaction is more intense once the animals have overcome higher costs. As a consequence, measures based on time with the resource may underestimate resource consumption at higher access costs, and demand curves derived from these measures may not be a true reflection of the value of different resources. An alternative approach to demand curves isreservation price, which is the maximum price individual animals are prepared to pay to gain access to resources. In studies using this approach, farmed mink (Mustela vison) paid higher prices for food and swimming water than for resources such as tunnels, water bowls, pet toys, and empty compartments. This indicates that the mink placed a higher value on food and swimming water than on other resources.     

Emotion,Sophistication and Political Behavior: Evidence From a Laboratory Experiment

The way emotions affect political behavior has been a central theme in politics since ancient times, but it is only in the past few decades that it has been the focus of rigorous empirical inquiry. Recent empirical research suggests that emotions may affect different groups of people in distinct ways, but experimental evidence remains scant. Through a double‐blind experiment, this article investigates the degree to which emotions (shame and anger) motivate people with different levels of political sophistication to be more politically active. The findings are two‐fold: (1) Once treated with shame, more sophisticated individuals are more likely to change their political behavior than less sophisticated ones; and (2) once treated with anger, it is people with low levels of prior political involvement who are more likely to report a change in their behavior. The findings highlight the potential of going beyond the existing investigations by adding shame in empirical analyses of how emotions affect behavioral change. The evidence here also shows that different emotions might display different patterns of interaction with sophistication. Practically, the findings point to an emotional venue for the mobilization of citizens who are generally difficult to engage in political life.     

Politics,concern for future generations,and the environment: Generativity mediates political conservatism and environmental attitudes

Climate change and pollution impact those alive today as well as future generations, suggesting that attitudes toward future generations may be linked with environmental attitudes. Despite the widespread impact of the environmental on human lives, there is considerable partisan divide in the United States with regards to environmental issues. We investigated relationships between political conservatism, generativity, and environmental attitudes in two studies (N = 429 and N = 618). Political conservatism was associated with lower pro‐environmental attitudes; however, political conservatism was also associated with higher generativity and had a positive indirect effect on pro‐environmental attitudes through higher generativity. More politically conservative individuals may have greater concern for future life and thereby have more pro‐environmental attitudes even while having lower pro‐environmental attitudes overall. These results likely reflect partisan polarization with regard to environmental issues. Pro‐environmental messages may be more persuasive for conservatives if they are linked to concerns about future generations.     

Some considerations about personality structure in child psychosis

This paper begins by describing the three main areas that can be addressed in seeking to bring about change in parent?–?infant work, and questions the extent to which a brief therapy model may be generally effective. Following a clinical example, there is a discussion of the nature of the process of change with this particular population. Drawing on ideas from Paula Heimann and others it is suggested that the ‘ghost in the nursery’ described by Fraiberg represents an ‘unassimilated object’ that may frequently be projected on to the infant but is also likely to appear elsewhere. It is argued that, especially if therapy relieves the infant of this projection, it will most often manifest its presence in the couple's relationship. In consequence, it is this relationship that should be a primary focus for our interventions, particularly as this also provides the essential context for the infant's psychological development.     

Sequence and priming in 15 month-olds' reactions to brief arm restraint: evidence for a hierarchy of anger responses

Brief, gentle arm restraint is widely used in experimental studies of children's anger, but the pattern of responses generated by such restraint has been incompletely described. We now describe a hierarchy of responses within trials as well as an escalation across trials that have both methodological and theoretical significance. Mothers of 87 15-month olds prevented them from playing with a toy by restraining their arms on two consecutive 30 sec trials. Physical struggling was the first and most frequent response; children who struggled were significantly more likely to vocalize, and those who vocalized were significantly more likely to show facial expressions of anger. The children's responses became more probable, rapid, and intense during Trial 2 restraint. Overall, the hierarchy was orderly enough to meet criteria for Guttman scalability. The particular sequence observed suggests situational, as opposed to bio-energetic, ordering of responses. Methodologically, the two trial paradigm is a simple, ecologically valid model for studying anger escalation that parallels the "attack priming" of aggression in other species. The magnitude and persistence of anger priming may provide novel measures of anger regulation. Theoretically, the existence of an orderly response hierarchy is consistent with previous observations suggesting that, within a situational context, the sequential appearance of specific behaviors may indicate progressive increases in anger intensity.     

An analysis of recollection in the measurement of long‐term change in attitudes

In cross‐sectional research designs, the measurement of attitudinal and behavioural change has often relied upon respondents' reported recollection of the degree of change from one point in time to another. Alternatively, algebraic approaches for measuring change are often utilized in longitudinal designs with panel data. In a conceptual replication of prior work by Irving and Meyer (1995), this study undertook an examination of direct recall measures of change, as well as contemporaneous Time 1 (T1) and Time 2 (T2) measures of three attitudinal constructs (union commitment, union satisfaction, and union attitudes in general) over a 10‐year period. Based upon a sample of 195 union members, the investigation found that more proximal T2 measures of the constructs of interest were strongly related to single‐item measures of recollection of change and more distal T1 measures had no significant relationship with respondents' reported recollection of any of the attitudinal measures examined. In the interpretation of these findings, it is suggested that current attitudes provide cognitive prompts to survey‐based requests for recollection of past attitudes, which may in‐turn lead to serious reporting inaccuracies associated with many direct measures of recollection.     

认知闭合需要研究评述

认知闭合需要是个体稳定的认知特征,描述了个体在面对模糊情境时是否愿意系统处理信息的动机。已有研究表明,认知闭合需要对个体的信息处理过程和决策结果有显著的预测能力。总体上说,高认知闭合需要的个体更容易利用启发式进行思考,因此此类个体更容易受到过度归因、首因效应等的影响。虽然大多数的研究表明认知闭合需要是个体稳定的认知特质,但也有研究者发现环境因素如噪音等可以在一定程度上、在短时期内改变个体的认知闭合需要的水平。因此,在相关研究中,认知闭合需要既可以通过量表测量,也可以通过在实验中改变环境噪音和时间压力等方法来操纵。已有的关于认知闭合需要的研究也有不足之处。首先,如何引导高认知闭合者克服匆忙做出决策的动机并采用分析式的方式处理信息和进行决策,目前的相关研究还很少;其次,已有的关于认知闭合的研究大都为实验室研究,因此这些研究的外部效度较低;第三,认知闭合需要在冲突研究领域的应用被忽略了。未来有必要针对这些不足之处进行相应研究     

Sociocultural influences on body dissatisfaction and body change behaviors among Malaysian adolescents

Little research on body dissatisfaction and body change behaviors, and the sociocultural influences on them, has been undertaken in non-Western contexts. The current study investigated these variables and the relationships between them among a sample of 529 Malaysian high school students (103 Malays, 344 Chinese and 82 Indians), who completed a set of measures in classroom settings. Chinese girls were more dissatisfied with their bodies than Chinese boys, but no gender difference was found for Malay and Indian participants. Girls were more likely to engage in behaviors to lose weight, and boys were more likely to engage in behaviors to increase muscle. The influence of sociocultural factors on body dissatisfaction and body change behaviors was limited and varied across both sex and ethnicity. Findings are discussed in relation to Western research, and it is concluded that cultural nuances need to be considered when investigating these phenomena.     

Genotype-environment interaction in personality development: identical twins reared apart

The focus of this study is to identify specific genotype-environment (GE) interactions as they contribute to individual differences in personality in later life. In behavioral genetics, GE interaction refers to the possibility that individuals of different genotypes may respond differently to specific environments. A sample of 99 pairs of identical twins reared apart, whose average age is 59 years, has been studied as part of the Swedish Adoption/Twin Study of Aging (SATSA). Hierarchical multiple regression was used to detect interactions between personality and environmental measures after the main effects of genotype and environment were removed. Analyses yield evidence for 11 significant interactions that provide the first evidence for GE interaction in human development using specific environmental measures. Thus, in addition to the main-effect contributions of heredity and environment, GE interactions contribute to individual differences in personality as measured in the second half of the life course.     

Mnemonic emotion regulation: a three-process model

Emotion regulation comprises attempts to influence when and how emotions are experienced and expressed. It has mostly been conceived of as proactive (e.g. situation selection) or reactive (e.g. attentional distraction), but it may also be retroactive and involve memory. I term such past-oriented activity mnemonic emotion regulation and propose that it involves increasing or decreasing access to or altering the characteristics of a memory. People may increase access to a memory and make it more likely that it will be retrieved in the future, for example by rehearsing a pleasant memory. They may decrease access to a memory and make it less likely that intrusions will be experienced in the future, for example by repeatedly trying to stop an unpleasant memory from being retrieved. Finally, people may alter the characteristics of a memory and change its content or context, for example by replacing a negative impression with a productive interpretation. I discuss how mnemonic emotion regulation may be instigated (e.g. via elaborate rehearsal) as well as the different motives (e.g. hedonic motives) people may have for engaging in regulation. Also, I discuss possible benefits of, variations in, and improvements of mnemonic emotion regulation.     

Synaesthesia,creativity and art: What is the link?

It has been suggested that individuals with synaesthesia may show heightened creativity as a result of being able to form meaningful associations between disparate stimuli (e.g. colour, sound). In this study, a large sample (N=82) of people with various kinds of synaesthesia were given two psychometric tests of creativity (Remote Associates Test, Alternate Uses Test) and were also asked about the amount of time engaged in creative arts (visual art, music). There was a significant tendency for synaesthetes to spend more time engaged in creative arts and this was, at least in part, dependent upon the type of synaesthesia experienced. For example, synaesthetes experiencing vision from music were far more likely to play an instrument than their other synaesthetic counterparts. There was no relationship between this tendency and the psychometric measures of creativity, but synaesthetes did outperform controls on one of the two psychometric measures (Remote Associates). We conclude that the tendency for synaesthetes to be more engaged in art is likely to have a different mechanism to psychometric measures of creativity, and that there is no direct link between them. Although synaesthetes may well perform better on some measures of creativity, we suggest that synaesthetes have better bottom‐up access to certain associations, but are not necessarily better able to use them flexibly (in divergent thinking).     

Effect of Icon Affiliation and Distance Moved on Detection of Icon Position Change on a Situation Awareness Display

Continuous gradual change is often difficult to detect, although it may be easy to detect the difference between the initial and end state if directly compared. Two experiments examined people's ability to detect gradual changes in icon position on a situation awareness map. People observed sequences of icon moves that consisted of ten .9-mm colinear moves or five 8.75-mm colinear moves and reported when they noticed a change. The relatively small moves were less likely to be detected than the relatively large moves; however, an entire sequence of the .9 mm moves was rarely missed. Green icon moves were significantly less likely to be detected than blue or yellow icon moves. This may have been due to the stimulus features of the icons or those features in interaction with the map background. Various methods that might assist icon change detection are discussed.
