意义维持模型:理论发展与研究挑战

意义维持模型是近年来兴起的社会心理学理论。它主张将意义维持作为个体最基本的社会动机,认为个体在遭受意义违反后,会激起厌恶性情绪,而缓解厌恶情绪成为意义维持的动力,促使个体采取补偿行为修补意义系统。该理论对认知失调等理论进行了一定程度的整合,并且具有强大而广泛的解释力。研究者对其意义违反、厌恶激起和行为补偿三个基本过程的理论阐述日臻完善,同时其主要观点也得到较多实证研究的支持。在意义维持模型的研究中,也存在意义等概念边界模糊、厌恶激起的中介作用论证不充分、启动和补偿的竞争解释等问题。今后的研究一方面需要进一步检验意义维持的基本过程,另一方面也可以讨论行为补偿的运作、主动的意义维持等问题。     

促进还是阻碍:情感对员工创造性绩效的影响

情感对员工工作行为的影响是组织行为研究领域中长期被忽视的内容。通过回顾积极与消极情感对创造性绩效影响的理论与实证研究,梳理相关的中介变量与调节变量的作用机理,构建出以任务特征、主管支持等组织背景因素为调节变量,以认知因素与动机因素为中介变量,积极与消极情感共存,并与情感强度等性质变量交互作用,最终影响员工创造性绩效的假设模型,为未来的研究工作提供了思路和方向。     

The Development of Symbolic Uses of Objects in Infants in a Triadic Context: A Pragmatic and Semiotic Perspective

In this study, we address the construction of the first symbolic uses of objects in contexts of triadic interaction (adult–child–object). We assume that symbolic productions are based on public rules of the use of objects previously agreed by the community. The first symbols are not rooted in any literal, evident reality, but in shared rules of uses about the material world. We observed six dyads communicating and interacting together with 10 objects in a semi‐structured situation longitudinally from 9 to 15 months of age. We found that the infants gradually constructed symbolic meanings, and we identified five symbolic levels and sublevels. At 9 months, the infants attended and engaged in the symbolic uses produced by an adult even though they themselves were not yet able to produce them. At 12 months, infants began to use objects symbolically to communicate with adults. The highest percentage of these first symbolic uses was of level 1, that is, with a close relation to the conventional use of the object used to perform the symbol. At 15 months, children increased their symbolic uses and performed symbolic uses at all levels, whereas adults reduced such practices. Adult semiotic mediation and the social meanings of objects can be considered important factors in children's symbolic productions. Copyright © 2014 John Wiley & Sons, Ltd.     

Finding the good in the bad: age and event experience relate to the focus on positive aspects of a negative event

All lives contain negative events, but how we think about these events differs across individuals; negative events often include positive details that can be remembered alongside the negative, and the ability to maintain both representations may be beneficial. In a survey examining emotional responses to the 2013 Boston Marathon bombings, the current study investigated how this ability shifts as a function of age and individual differences in initial experience of the event. Specifically, this study examined how emotional importance (i.e. self-reported emotional arousal and personal significance), involvement (i.e. self and friend/family involvement in the 2013 Boston Marathon and self-involvement in prior marathons), and self-reported surprise upon hearing about the event related to the tendency to report focusing on the negative and positive aspects of the bombings. Structural equation models revealed that while greater emotional importance and surprise were associated with a greater focus on negative elements, involvement and age were associated with increased consideration of positive aspects. Further, emotional importance was more strongly related to an increased focus on negative aspects for young adults and an increased focus on positive aspects for older adults, highlighting a tendency for older adults to enhance positive features of an otherwise highly negative event.     

Does the two-chair dialogue intervention facilitate processing of emotions more efficiently than basic Rogerian conditions?

Processing difficult emotions is assumed to be of importance in therapeutic change. In this study, we examine whether a two-chair dialogue in Emotion-focused Therapy (EFT) is associated with a change in emotional processing, measured as changes in emotional arousal and emotional experiencing. In a multiple baseline design, 20 clients in treatment for depression or anxiety first received five, seven or nine weekly sessions of baseline treatment providing Rogerian conditions and affect attunement. In the second phase, two-chair intervention was added for the five consecutive sessions. All sessions were subdivided into 2 min segments which were rated using the Client Emotional Arousal Scale III and the Experiencing Scale. Analyses indicated a significantly higher number of high-arousal segment in the latter phase. Individual clients’ change trajectories were not significantly steeper in the second phase. Experiencing increased throughout both phases of treatment. However, after introducing the two-chair dialogue the Experiencing change trajectory was not significantly steeper than in the baseline phase. Findings suggest that both the two-chair dialogue and the Rogerian conditions with affect attunement focus are effective in facilitating emotional processing. Results are consistent with previous research, suggesting that the two-chair dialogue is an emotionally evocative intervention. Implications and limitations are discussed.     

The relationship between aggressive and sexual behavior in male mice: Effects of testosterone and parachlorophenylalanine

The purpose of this study was to clarify the connection between aggressive and sexual behavior with the aid of testosterone propionate (TP) and parachlorophenylalanine (PCPA). Previous studies have indicated that aggressive and sexual behavior are positively correlated, and it has been suggested that both behaviors are related to the level of general arousal. Testosterone has documented effects on both aggressive and sexual behavior. It has been hypothesized that these effects are due to an increased level of general arousal. If this is the case, aggressive and sexual behavior could be restored by administration of drugs excitating the central nervous system, e.g., PCPA. The present study examined the effects of TP and PCPA on aggressive and sexual behavior in gonadectomized male mice. Control animals were injected with sesame seed oil or saline. The level of aggressiveness was assessed by means of dyadic tests with gonad-intact male opponents. For the sexuality tests, a receptive female was placed in the home cage of the experimental male. The results showed that male mice injected with PCPA were more aggressive than the males of the other groups, while the TP-exposed males expressed the most sexual activity. Compared to the control group, the PCPA and TP groups were more active in both the aggression and the sexuality tests. These findings lend support to the hypothesis that the earlier documented correlations between aggressive and sexual behavior could be due to both behaviors being dependent on a certain level of general activation.

Self-reported change in health behaviour after a mass media-based health education campaign

A comprehensive short-term fund-raising campaign, was launched in 1987 by a health charity organization in cooperation with the only Norwegian TV-channel covering the whole country. The campaign which was extensively announced on TV and other media and which involved large proportions of the population, finished up with a six hour TV-show on the fund-raising day. Because a considerable amount of information on prevention of heart disease was presented in connection with the campaign, it is presently evaluated as a nationwide health education campaign. Twenty-two per cent of the population reported changes in one or more habits in connection with the campaign (one third of them took more exercise, while one quarter reduced/quit their smoking). Health behaviour change among family/friends, reported new knowledge of health and worry created by the campaign, were the factors most clearly associated with self-reported behaviour change. The paper discusses the magnitude of the effects of the campaign in relation to the study design, and the importance of social environment and fear arousal on health behaviour.     

An attempt towards differentiating attentional deficits in traumatic brain injury

Attentional deficits in patients suffering traumatic brain injury (TBI) can occur with minor to severe impact to the brain. Based on reviews of both the cognitive and neurobehavioral literature, the following three concepts of attention are addressed: (a) arousal/alertness, (b) selective attention, and (c) energetic aspects of attention, which include such components as effort, resource allocation, and speed of processing. Within each concept, definitions are proposed, the underlying brain mechanisms are identified, and the specific deficits associated with TBI are explored. This review combines theoretical perspectives and clinical findings with the objective of leading toward a diagnostic differentiation that in turn will benefit treatment planning.
