Group‐analytic network process for balancing stakeholder views on fire protection of steel‐framed buildings

To select appropriate fire protection options for buildings during their design stage, economic, safety, environmental, and societal criteria need to be accounted for. The divergent and sometimes conflictual desires from different fire design stakeholders involved in the process present a multicriteria decision problem. Design decision criteria and fire protection options can be interdependent, and so there is a need to manage these desires with an advanced decision analysis technique, thereby reducing uncertainties in the complex decision‐making process. The aim of this paper is to use the weighted/geometric mean method‐analytic network process (W/GMM‐ANP) to balance the opinions of fire design stakeholders extracted from 42 structured stakeholder interviews on selecting the most suitable fire protection option for buildings constructed of steel frames. Different categories of interdependent decision elements were developed from 22 design decision criteria and 5 proposed fire protection options to produce a network of decision clusters for multicriteria decision analysis. In the synthesis and ranking of fire protection options, the W/GMM‐ANP accounted for the multiple interdependencies of weighted and unweighted stakeholder desires and managed the complexity of the decision‐making problem. The technique is proposed for approaching suitable group decisions in structural fire design of steel‐framed buildings as well as other performance‐based engineering decision making that may involve multidisciplinary stakeholders.

注视方向和面部表情对注意朝向的影响

摘 要 本文以三种表情面孔为材料,运用事件相关电位（ERP）方法探讨表情线索在注意朝向中与注视转移发生的交互及两者如何共同影响观察者的反应。结果发现：（1）线索效应在三种表情面孔的两种SOA中都出现了;（2）SOA较长时,注视线索效应量间的显著差异出现在中性和恐惧面孔、高兴和恐惧面孔间;（3）面部表情的效应出现在了表情线索诱发的P1成分上;（4）目标诱发的P1和N1说明了注视线索效应的存在及与表情间的交互。结论：表情线索先对观察者的朝向反应产生影响,随后是注视线索及其与表情线索发生的交互。     

内隐自尊的特性：来自EAST的证据

采用外部情绪性Simon任务（EAST）对109名大学生对代表自我和他人的刺激词的态度差异进行测量,从而探讨内隐自尊的特性。结果显示：在个体的认知图式中,对自我持有一种内隐的积极的评价或态度,对他人持有一种内隐的相对消极的评价或态度。具体表现在：（1）内隐自尊的特性是将自己与积极的评价和情感相联系,将他人与消极的评价和情感相联系;（2）自我姓名激活的积极的内隐自我态度比一般性自我词更为强烈,而他人姓名激活的消极的内隐态度比一般性非我词更弱。本研究表明,EAST能有效检测出内隐自尊效应,并可以同时获得个体对自我和他人的内隐态度的强度和方向,为内隐自尊研究提供了一种新的有效的方法,但其应用仍需谨慎。     

Tag, you're it: Tagging as an alternative to yes/no recognition in item method directed forgetting

The current study contrasted a standard yes/no recognition task with a tagging recognition task in the context of an item-method directed forgetting paradigm. During the study phase, a series of words was presented one at a time, each followed by an instruction to remember (R) or forget (F). The retention of R and F study words was tested using either a typical yes/no recognition task or a tagging recognition task in which participants labeled each word as “R”, “F” or “New”. The directed forgetting effect observed in each task was equivalent in magnitude. However, the tagging recognition task afforded an additional analysis of the errors of misattribution that was not possible with the more typical yes/no recognition task. Interestingly, when falsely recognizing a Foil word, participants were more likely to assign an “F” tag than an “R” tag. These errors of misattribution are consistent with existing accounts of directed forgetting that suggest R words are better encoded than F words. We argue for the utility of the tagging procedure, given it does not alter the directed forgetting effect normally seen with yes/no recognition but provides additional information about errors of misattribution.     

An Analogue Study of the Psychological and Psychosocial Processes Associated With Post‐concussion Symptoms

This study used an analogue design to investigate post‐concussion syndrome and the psychological and psychosocial processes associated with post‐concussion symptom (PCSx) reporting. The study examined the role of expectation in reporting of PCSx, the nature of associated psychological and psychosocial difficulties, and the “good‐old‐days” phenomenon. Forty‐five healthy participants were randomly assigned to one of two groups: (1) a control group or (2) an expectation group who were asked to perform as if they had experienced a mild traumatic brain injury. Fourteen psychiatric patients comprised the clinical group. Self‐report questionnaires assessing PCSx and psychological and psychosocial variables were administered. It was hypothesised that PCSx would be non‐specific, that the expectation group would report greater dysfunction than controls, and that the “good‐old‐days” phenomenon would cause the expectation and clinical groups to underestimate pre‐morbid PCSx. All participants reported some degree of dysfunction, and the expectation and clinical groups underestimated past PCSx. The expectation group reported more PCSx and psychological and psychosocial dysfunction than controls, resembling the clinical group. The results demonstrate that expectation can cause otherwise healthy individuals to resemble a clinical group in terms of their level of endorsement of psychological and psychosocial dysfunction.     

The 'secret cocoon': fantasies about the private self in the absence of consensual reality

Clinical material is presented from an analysand whose defense of withdrawal to 'a private internal space' was mobilized when she became confused, within her relationships and within the transference, about whose understanding of a shared event was 'real.' Analysis of the defense as resistance revealed a disrupted sense of connection to others and to the analyst in the face of the difficulty in determining a consensual reality. This was accompanied by emotional withdrawal, with a complex fantasy of retreat to a protective inner hiding place, or cocoon. The phenomenology and functions of such withdrawals, the fantasies accompanying them, and the ways in which they changed during the analysis are discussed in this paper. For the patient described, the analysis of her shifting 'cocoon' states and of the fantasies connected with them eventually enabled her to access her creative 'private self' more freely and with less conflict.     

Differentiating challenge reactivity from psychomotor activity in studies of children's psychophysiology: considerations for theory and measurement

Current methods of assessing children’s physiological “stress reactivity” may be confounded by psychomotor activity, biasing estimates of the relation between reactivity and health. We examined the joint and independent contributions of psychomotor activity and challenge reactivity during a protocol for 5- and 6-year-old children (N = 338). Measures of parasympathetic reactivity (respiratory sinus arrhythmia [RSA]) and sympathetic reactivity (preejection period [PEP]) were calculated for social, cognitive, sensory, and emotional challenge tasks. Reactivity was calculated relative to both resting and a paired comparison task that accounted for psychomotor activity effects during each challenge. Results indicated that comparison tasks themselves elicited RSA and PEP responses, and reactivity adjusted for psychomotor activity was incongruent with reactivity calculated using rest. Findings demonstrate the importance of accounting for confounding psychomotor activity effects on physiological reactivity.     

Reading Susan Isaacs: toward a radically revised theory of thinking

The author views Isaacs's (1952) paper, The nature and function of phantasy, as making an important contribution to the development of a radically revised psychoanalytic theory of thinking. Perhaps Isaacs's most important contribution is the notion that phantasy is the process that creates meaning, and that phantasy is the form in which all meanings - including feelings, defense 'mechanisms,' impulses, bodily experiences, and so on - exist in unconscious mental life. The author discusses both explicit formulations offered by Isaacs as well as his own extensions of her ideas. The latter include (1) the idea that phantasying generates not only unconscious psychic content, but also constitutes the entirety of unconscious thinking; (2) the notion that transference is a form of phantasying that serves as a way of thinking for the first time (in relation to the analyst) emotional events that occurred in the past, but were too disturbing to be experienced at the time they occurred and (3) a principal aim and function of phantasy is that of fulfilling the human need to get to know and understand the truth of one's experience. The author concludes by discussing the relationship between Isaacs's concept of phantasy and Bion's concepts of alpha function and the human need for the truth, as well as the differences between Fairbairn's and Isaacs's conceptions of the nature of unconscious internal object relationships.
