Recruitment sources and organizational attraction: A field study of Belgian nurses

Previous research on recruitment sources has mostly focused on posthire instead of prehire outcomes and has typically applied a very rudimentary classification of sources on the basis of the formal–informal distinction. The present study relied on a theory-driven taxonomy to identify four major types of recruitment sources (recruitment advertising, recruitment events, publicity, and word of mouth) and applied a source credibility perspective to predict differential relationships of these sources with organizational attractiveness. In a sample of 184 job-seeking nurses in Belgium, characterized by a high labour market demand, it was found that job seekers who spent more time on receiving employment information through experiential recruitment sources such as events and word of mouth perceived this information as more credible. In addition, job seekers' exposure to word of mouth was strongly positively related to their attraction to organizations as an employer. This relationship was partially mediated by the perceived credibility of the received employment information. Therefore, the results of this field study suggest that to enhance their attractiveness as an employer for job seekers, especially those in high demand on the labour market, recruiting organizations should provide credible employment information and stimulate the use of word of mouth as a recruitment source.     

Readers' reliance on source credibility in the service of comprehension

The current project examined the impact of knowledge about the credibility of sources on readers' processing of texts. Participants read texts in which information about characters was provided by either a credible or a noncredible source; this information suggested that the character potentially possessed a particular trait. A subsequent text episode offered the opportunity for participants to apply any inferred trait to their understanding of unfolding story events. In Experiment 1, participants' moment-by-moment reading times indicated strong expectations for characters to behave in trait-consistent ways, with little effect of credibility on those expectations. Experiments 2 and 3 provided participants with additional encouragement to attend to credibility during reading, but these experiments also revealed little influence of credibility. In Experiment 4, in addition to being given added encouragement, participants were explicitly asked to evaluate the likelihood of future text events; under these conditions, expectations for story outcomes were influenced by the credibility of information sources. This influence was mediated by the degree to which participants self-reported relying on credibility during the task. These findings have implications for contemporary accounts of text comprehension, persuasion, and individual differences in credibility assessment.

Perceived Perpetration During Traumatic Events: Clinical Suggestions From Experts in Prolonged Exposure Therapy

Prolonged exposure therapy (PE) is a treatment that has proven effectiveness in reducing the symptoms of posttraumatic stress disorder (PTSD) and related psychopathology. Providing PE to trauma survivors with PTSD, particularly related to combat trauma, often involves addressing guilt or shame related to their contextually appropriate use of violence and lethal force. In this paper, we present 4 clinical case vignettes in order to define the concept of perceived perpetration, and offer clinical suggestions for assessment and treatment with PE. Specifically, we examined issues such as identifying what type of traumatic events are appropriate for the use of PE, how to approach issues surrounding actions that could be perceived as perpetration, and attending to trauma-related guilt or shame.     

Political accountability,public constitution of recent past and the collective memory of socio‐political events: A discursive analysis

This paper presents a discursive analysis of a political news interview as a site for the interactional organization of the public constitution of recent past. In a context of commemoration and finding out the truth about the past, the focus is on how the collective memory of socio‐political events and political accountability is managed and what discursive practices representatives of nation‐states draw upon to understand and construct ideological representations of socio‐political events, namely the Romanian ‘revolution’ of 1989. The analysis shows how the possibility versus the actuality of knowing the truth about the events, (political) accountability and stake for actions are discussed, framed and given significance by constituting the ‘events’ of 1989 as ‘revolution’. The analysis further reveals how this ascribed categorial meaning is used by the interviewee as background for delegitimizing critical voices and sidestepping responsibility for past actions and knowing the truth. Social and community psychologists can learn more about how individuals and communities construct ideological versions of socio‐political events by considering the interplay between questions of political accountability and arguments over the meaning of political categories, and engaging with the accounting practices in which the meaning of socio‐political events is being negotiated by members of society Copyright © 2010 John Wiley & Sons, Ltd.     

On computing ELECTRE's credibility indices under partial information

The ELECTRE family of decision aid methods is a well‐known approach to help decision makers (DMs) advance in a decision process. Among the most recent methods in the family, ELECTRE IS, III, and TRI compute fuzzy indices for the credibility of a given action outranking some other. We consider the case when the DMs are unsure which values each parameter should take, which may result from insufficient, imprecise or contradictory information, as well as from different preferences among a group of DMs. In the framework of a robustness analysis approach, where DMs provide only partial information on the parameter values (through constraints on acceptable combinations), we study how to find whether an outranking among two actions in an ELECTRE method is robust. In this context, we study the resulting nonlinear problems of optimizing a credibility index (under the type of constraints that we consider to appear in practice) and present some examples.

Does partisan media make a pawn of mistrust? Institutional trust and preventive COVID-19 health behaviors in a polarized pandemic

In a rapidly developing crisis such as the COVID-19 pandemic, people are often faced with contradictory or changing information and must determine what sources to trust. Across five time points (N = 5902) we examine how trust in various sources predicts COVID-19 health behaviors. Trust in experts and national news predicted more engagement with most health behaviors from April 2020 to March 2022 and trust in Fox news, which often positioned itself as counter to the mainstream on COVID-19, predicted less engagement. However, we also examined a particular public health behavior (masking) before and after the CDC announcement recommending masks on 3 April 2020 (which reversed earlier expert advice discouraging masks for the general public). Prior to the announcement, trust in experts predicted less mask-wearing while trust in Fox News predicted more. These relationships disappeared in the next 4 days following the announcement and reversed in the 2 years that follow, and emerged for vaccination in the later time points. We also examine how the media trusted by Democrats and Republicans predicts trust in experts and in turn health behaviors. Broadly we consider how the increasingly fragmented epistemic environment has implications for polarization on matters of public health.     

Developmental changes in the discrimination of dynamic human actions in infancy

Recent evidence suggests that adults selectively attend to features of action, such as how a hand contacts an object, and less to configural properties of action, such as spatial trajectory, when observing human actions. The current research investigated whether this bias develops in infancy. We utilized a habituation paradigm to assess 4-month-old and 10-month-old infants' discrimination of action based on featural, configural, and temporal sources of action information. Younger infants were able to discriminate changes to all three sources of information, but older infants were only able to reliably discriminate changes to featural information. These results highlight a previously unknown aspect of early action processing, and suggest that action perception may undergo a developmental process akin to perceptual narrowing.     

Analysis of recent empirical challenges to an account of interceptive timing.

How do we perceive how long it will be before we reach a certain place when running, driving, or skiing? How do we perceive how long it will be before a moving object reaches us or will arrive at a place where it can be hit or caught? These are questions of how we temporally coordinate our actions with a dynamic environment so as to control collision events. Much of the theoretical work on the control of these interceptive actions has been united in supposing that (1) timing is functionally separable from positioning and the two are controlled using different types of information; (2) timing is controlled using special-purpose time-to-arrival information; (3) the time-to-arrival information used for the timing of fast interceptive actions is a first-order approximation to the actual time-to-arrival, which does not take accelerations into account. Challenges to each of these suppositions have recently emerged, suggesting that a complete rethinking of how interceptions are controlled may be necessary. These challenges are analyzed in detail and it is shown that they are readily accommodated by a recent theory of interceptive timing based on the points just noted.

Event structure in perception and conception

Events can be understood in terms of their temporal structure. The authors first draw on several bodies of research to construct an analysis of how people use event structure in perception, understanding, planning, and action. Philosophy provides a grounding for the basic units of events and actions. Perceptual psychology provides an analogy to object perception: Like objects, events belong to categories, and, like objects, events have parts. These relationships generate 2 hierarchical organizations for events: taxonomies and partonomies. Event partonomies have been studied by looking at how people segment activity as it happens. Structured representations of events can relate partonomy to goal relationships and causal structure; such representations have been shown to drive narrative comprehension, memory, and planning. Computational models provide insight into how mental representations might be organized and transformed. These different approaches to event structure converge on an explanation of how multiple sources of information interact in event perception and conception.     

Surface features of utterances, credibility judgments, and memory

Information acquired in conversation is often not credible, which makes monitoring its credibility critical. Listeners of conversations often use surface features of utterances, such as pause and intonation, to guide their credibility judgments. In this research, we explore whether listeners' delayed credibility judgments about remembered information are affected by the surface features of the speakers' utterances. In addition, we examine some of the specific factors involved in this issue: (1) how listeners' listening strategies influence their subsequent credibility judgments and (2) how the type of surface features of the utterances influences listeners' ability to make delayed credibility judgments. The results indicate that intonation of the utterances continues to influence listeners' assessment of the credibility of remembered information, that the influences of intonation depend on listening strategies, and that people have difficulty using/remembering pause length when making a delayed credibility judgment. The implications of these findings are discussed.     

Combining information from sources that vary in credibility

Models describing the role of source credibility in information integration were tested in two experiments. In the first experiment, subjects estimated the value of used cars based on two cues: blue book value and an estimate provided by one of three friends who examined the car. The three sources were described as differing in mechanical expertise. In the second experiment, subjects rated the likeableness of persons described by either one or two adjectives, each adjective contributed by a different source. The sources differed with respect to the length of their acquaintance with the person to be rated. In both experiments, credibility of the source magnified the impact of the information he provided. Further, this multiplicative effect of a source was inversely related to the credibility of the other source, in violation of additive or constant-weight averaging models, but consistent with a relative-weight averaging model.     

Age differences in the effects of social influence on children's eyewitness performance and their metacognitive monitoring

The current work investigated the effects of social influence on children's recall accuracy and metacognitive monitoring. Two studies were conducted in which 8- and 10-year-olds were confronted with postevent information in an interview situation. An interviewer (Study 1) or a confederate (Study 2) provided postevent information with two levels of assertiveness, inducing (a) a variation of conformity pressure and (b) a variation of information credibility. Afterwards, children's confidence judgments were assessed. The results revealed significant age differences in children's ability to adequately cope with variations of social influence. Although conformity pressure was especially important for the 8-year-olds, effects of informative social influence were independent of age. However, 10-year-olds were also able to act appropriately on low credibility, thereby demonstrating a more sophisticated consideration of social influence sources. Moreover, varying assertiveness also affected the quality of children's confidence judgments by improving their metacognitive differentiation skills.     

Inferring action structure and causal relationships in continuous sequences of human action

In the real world, causal variables do not come pre-identified or occur in isolation, but instead are embedded within a continuous temporal stream of events. A challenge faced by both human learners and machine learning algorithms is identifying subsequences that correspond to the appropriate variables for causal inference. A specific instance of this problem is action segmentation: dividing a sequence of observed behavior into meaningful actions, and determining which of those actions lead to effects in the world. Here we present a Bayesian analysis of how statistical and causal cues to segmentation should optimally be combined, as well as four experiments investigating human action segmentation and causal inference. We find that both people and our model are sensitive to statistical regularities and causal structure in continuous action, and are able to combine these sources of information in order to correctly infer both causal relationships and segmentation boundaries.     

Exploring the Individual's Perception of Sources and Credibility of Feedback in the Work Environment

This study reports on the construction of an instrument to assess individuals' perceptions of feedback from various sources in a work environment, and to investigate the effects of the sources' credibility on those perceptions. Six dimensions were found to reflect the sources of feedback and the type of information they convey, and 10 dimensions were found to represent the degree of credibility the individual attributes to the sources of feedback. Data collected from a heterogeneous sample of 706 employees in the UK and Brazil were analysed to establish the reliability and construct validity of the questionnaire.     

Distance effects in memory for sequences: evidence for estimation and scanning processes

The current study sought to uncover how temporal information is represented in our knowledge about routine events. In Experiment 1 we collected norming data on eight routines taken from Galambos (1983). In Experiment 2 participants were presented with two actions of varying distance from a routine and asked "Are the actions in the correct order?". We found that a number of variables interact with distance, including action position, routine familiarity, and experimental block. These data suggest that sometimes participants are faster when the actions are far apart in the routine, while at other times they are faster when actions are closer together, providing evidence for both distance and reverse-distance effects, respectively. A model is presented to help interpret these data in which temporal information for routine events is both: (1) coarsely coded, and processed by an estimation mechanism; and (2) represented serially, and processed by a scanning mechanism.     

在动态认知逻辑中融合观察与内省

一直以来,我们使用逻辑系统来描述数学的证明、结构的计算以及语言的意义。近年来,逻辑系统却越来越多地被用来研究理性行动者的很多方面。例如,如何接受单一的信息,多主体间的交流行为,以及更为一般的受目标驱动的主体间的互动。特别是,对观察和交流中的信息流的研究,大家使用所谓的知识更新、信念修正和偏好改变的动态认知逻辑。当新信息进来时,这些逻辑使用信息的“语义意义”作为被更新状态的选择范围。 然而,同样重要的是,理性主体的行动也会基于其他信息,譬如,由推理和反省得到的信息。对这些问题的研究实际上是对信息在更为语法的意义上进行理解的,即,把信息看作是可以由主体阐明的东西。也许有些奇怪,尽管在这一领域已经存在不少的研究方案,但是大家对什么是信息,信息的关键机制是什么等问题更少有一致的意见。可以看出,对“信息”的意义在逻辑中确实有很多不同的理解。 本文基于可能世界的语义,给出一个一致的信息模型,同时也赋予可能世界语法的“可及通路”。这样,我们就能把外部的“更新信息”和内部的“阐明信息”放在同一个动态逻辑系统中。特别是,我们提出了两个基本的信息行动：纯粹的基于观察的更新（“单纯的看”）和把不明显的知识变为明显知识的“知觉实现”。我们阐明为什么这些行动是自然的,同时我们也提出了一些新的研究问题。其中,很多问题探讨如何使其他的逻辑传统,包括信念修正理论、情景语义学和弗协调逻辑等适用于信息一驱使的理性行动者的图景。     

Memory processes in elderly eyewitnesses: What we know and what we don't know

Research is reviewed on the memory abilities of elderly eyewitnesses. Two major issues are addressed: First, how credible are elderly witnesses? Second, how accurate are they? Despite negative stereotypes regarding elderly eyewitnesses, they do not necessarily lack credibility at trial. In terms of their memory performance, older witnesses are as accurate as young adults in many respects, but they are particularly vulnerable to misleading information that is presented after the witnessed event. Furthermore, their performance varies depending on the type of information that is sought and the manner in which their memory is assessed. Recommendations are made for improving the reliability of testimony that is offered by elderly eyewitnesses.
