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.     

认知分心的强度对创伤性信息加工的影响

结合ERP技术、创伤电影范式和改进的工作记忆范式探讨了认知分心的强度对创伤性信息加工的影响。结果发现, (1)高负荷上的N2波幅显著大于低负荷上的。(2)在低工作记忆负荷上, 创伤负性图引发的LPP波幅显著大于创伤中性图和无关中性图; 而在高工作记忆负荷上, 三类图片引发的LPP波之间差异不再显著。(3)在创伤负性图上高、低负荷工作记忆任务诱发的LPP波差异显著, 且高负荷条件下的LPP波幅显著小于低负荷条件。结果表明, 相比低认知控制, 早期高认知控制对创伤性信息的调节更有效, 支持了认知控制理论。

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.     

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.     

Early processing of emotional faces in children with autism: An event-related potential study

Social deficits are one of the most striking manifestations of autism spectrum disorders (ASDs). Among these social deficits, the recognition and understanding of emotional facial expressions has been widely reported to be affected in ASDs. We investigated emotional face processing in children with and without autism using event-related potentials (ERPs). High-functioning children with autism (n = 15, mean age = 10.5 ± 3.3 years) completed an implicit emotional task while visual ERPs were recorded. Two groups of typically developing children (chronological age-matched and verbal equivalent age-matched [both ns = 15, mean age = 7.7 ± 3.8 years]) also participated in this study. The early ERP responses to faces (P1 and N170) were delayed, and the P1 was smaller in children with autism than in typically developing children of the same chronological age, revealing that the first stages of emotional face processing are affected in autism. However, when matched by verbal equivalent age, only P1 amplitude remained affected in autism. Our results suggest that the emotional and facial processing difficulties in autism could start from atypicalities in visual perceptual processes involving rapid feedback to primary visual areas and subsequent holistic processing.     

Adolescent(e)s à haut potentiel intellectuel : des configurations familiales plurielles

This research captures the diversity of family patterns among gifted adolescents (IQ ≥ 130). Data on the perceived parental's support and investment in schooling, family relationships and sociobiographic characteristics were collected by questionnaire from 255 French junior high school gifted students (48 girls, 207 boys), aged 9 to 15 (M = 12.5; SD = 1.51). A hierarchical cluster analysis highlights the existence of four types differentiated, thereby going against a standardized and stereotypical representation of this population.     

Regional differences in the listener's phonemic inventory affect semantic processing: A mismatch negativity (MMN) study

Using the mismatch negativity (MMN) response, we examined how Standard French and Southern French speakers access the meaning of words ending in /e/ or /ε/ vowels which are contrastive in Standard French but not in Southern French. In Standard French speakers, there was a significant difference in the amplitude of the brain response after the deviant-minus-standard subtraction between the frontocentral (FC) and right lateral (RL) recording sites for the final-/ε/ word but not the final-/e/ word. In contrast, the difference in the amplitude of the brain response between the FC and RL recording sites did not significantly vary as a function of the word’s final vowel in Southern French speakers. Our findings provide evidence that access to lexical meaning in spoken word recognition depends on the speaker’s native regional accent.     

Intelligence and physical attractiveness

This brief research note aims to estimate the magnitude of the association between general intelligence and physical attractiveness with large nationally representative samples from two nations. In the United Kingdom, attractive children are more intelligent by 12.4 IQ points (r = .381), whereas in the United States, the correlation between intelligence and physical attractiveness is somewhat smaller (r = .126). The association between intelligence and physical attractiveness is stronger among men than among women in both nations. The association remains significant net of a large number of control variables for social class, body size, and health.
