Models of Interpersonal Trust Development: Theoretical Approaches, Empirical Evidence, and Future Directions

Most research on trust has taken a static, “snapshot” view; that is, it has approached trust as an independent, mediating, or dependent variable captured by measuring trust at a single point in time. Limited attention has been given to conceptualizing and measuring trust development over time within interpersonal relationships. The authors organize the existing work on trust development into four broad areas: the behavioral approach and three specific conceptualizations of the psychological approach (unidimensional, two-dimensional, and transformational models). They compare and contrast across these approaches and use this analysis to identify unanswered questions and formulate directions for future research.

Trust Repair After An Organization-Level Failure

We propose a systemic, multilevel framework for understanding trust repair at the organizational level. Drawing on systems theory, we theorize how each component of an organizations system shapes employees’ perceptions of the organizations trustworthiness and can contribute to failures and effective trust repair. We distinguish the framework from prior work grounded in dyadic assumptions and propose underlying principles and a four-stage process for organizational trust repair. Finally, we explore the implications for research and practice.

Cross-modal links in exogenous covert spatial orienting between touch, audition, and vision

Three experiments investigated cross-modal links between touch, audition, and vision in the control of covert exogenous orienting. In the first two experiments, participants made speeded discrimination responses (continuous vs. pulsed) for tactile targets presented randomly to the index finger of either hand. Targets were preceded at a variable stimulus onset asynchrony (150,200, or 300 msec) by a spatially uninformative cue that was either auditory (Experiment 1) or visual (Experiment 2) on the same or opposite side as the tactile target. Tactile discriminations were more rapid and accurate when cue and target occurred on the same side, revealing cross-modal covert orienting. In Experiment 3, spatially uninformative tactile cues were presented prior to randomly intermingled auditory and visual targets requiring an elevation discrimination response (up vs. down). Responses were significantly faster for targets in both modalities when presented ipsilateral to the tactile cue. These findings demonstrate that the peripheral presentation of spatially uninforrnative auditory and visual cues produces cross-modal orienting that affects touch, and that tactile cues can also produce cross-modal covert orienting that affects audition and vision.

Leadership and trust: Their effect on knowledge sharing and team performance

Team leaders who facilitate knowledge sharing and engender trust contribute to team effectiveness. While the separate effects of leadership, trust and knowledge sharing on team performance are well documented, few scholars have investigated the specific links between these factors. This study examines the relationship between the leader as the knowledge builder, trust in the leader and in the team, knowledge sharing and team performance. Surveys were collected from 34 engineering project teams (n=166 team members, 30 team leaders) and 18 managers in a large automotive organization. The results indicate that by building the team’s expertise, leaders enhance team members’ willingness to rely on and disclose information in the team, which in turn increases team knowledge sharing. Team knowledge sharing significantly predicted leaders’ and managers’ ratings of team performance. The theoretical and practical implications of the findings are discussed.

The Role of Personality in the Job Demands-Resources Model: A Study of Australian Academic Staff.

Purpose ‐ The central aim of this study is to incorporate two core personality factors (neuroticism and extroversion) in the job demands-resources (JD-R) model. Design/methodology/approach ‐ It was hypothesized that neuroticism would be most strongly related to the health impairment process, and that extroversion would be most strongly related to the motivational process. The hypotheses were tested in a sample of 3,753 Australian academics, who filled out a questionnaire including job demands and resources, personality, health indicators, and commitment. Findings ‐ Results were generally in line with predictions. Structural equation modeling analyses showed that job demands predicted health impairment, while job resources predicted organizational commitment. Also, neuroticism predicted health impairment, both directly and indirectly through its effect on job demands, while extroversion predicted organizational commitment, both directly and indirectly through its effect on job resources. Research limitations/implications ‐ These findings demonstrate the capacity of the JD-R model to integrate work environmentandindividual perspectives withinasinglemodel of occupational wellbeing. Practical implications ‐ The study shows that working conditions are related to health and commitment, also after controlling for personality. This suggests that workplace interventions can be used to take care of employee wellbeing. Originality/value ‐ The paper contributes to the literature by integrating personality in the JD-R model, and shows how an expanded model explains employee wellbeing.

Trust differences across national-societal cultures: Much to do, or much ado about nothing?

Does trust and its development, functions and meaning, differ between people from different national–societal cultures? There is considerable anecdotal evidence and some theoretical argumentation to suggest it does, but are these supported by empirical research? This chapter reviews the available empirical evidence on the effects of national–societal culture on interpersonal trust. It focuses largely on quantitative empirical evidence to consider the extent to which, and the ways in which, interpersonal trust differs across national–societal cultures. In every category of our review we found evidence of cross-cultural differences, particularly on generalized trust, and also evidence of trust universals across cultures. In evaluating these findings, we conclude that trust may operate as a variform universal and variform functional universal. We conclude with two proposed routes for future research, and implications for practice. Introduction To an ever-increasing extent, ‘work’ involves close interaction and cooperation with people who come from a national–societal cultural background different from ones own. This emerging reality of work can be attributed to a number of factors. First, with the unrelenting advance of globalization, more and more organizations are taking a global approach to operations, including the operation of overseas international joint ventures and alliances, working with offshore suppliers and customers, and conducting global searches for talent. Second, the advance of communication technologies such as e-mail and videoconferencing has fostered a movement toward global virtual teams involving individuals from a variety of different cultural backgrounds.

Effects of memory load and distraction on performance and event-related slow potentials in a visuospatial working memory task

Brain electrical activity related to working memory was recorded at 15 scalp electrodes during a visuospatial delayed response task. Participants (N = 18) touched the remembered position of a target on a computer screen after either a 1 or 8 sec delay. These memory trials were compared to sensory trials in which the target remained present throughout the delay and response periods. Distractor stimuli identical to the target were briefly presented during the delay on 30% of trials. Responses were less accurate in memory than sensory trials, especially after the long delay. During the delay slow potentials developed that were significantly more negative in memory than sensory trials. The difference between memory and sensory trials was greater at anterior than posterior electrodes. On trials with distractors, the slow potentials generated by memory trials showed further enhancement of negativity, whereas there were minimal effects on accuracy of performance. The results provide evidence that engagement of visuospatial working memory generates slow wave negativity with a timing and distribution consistent with frontal activation. Enhanced brain activity associated with working memory is required to maintain performance in the presence of distraction.

Unravelling the complexities of trust and culture

Badri is an Iranian businesswoman representing her firm in first-round negotiations with a new alliance partner from Munich, Germany. When she enters the room, her counterpart from the German firm, Johann, reaches out his hand for her to shake as a first gesture of goodwill. Badri hesitates, but takes Johannʹs hand briefly, shakes it once, smiling the whole time. Then she sits down. Johann is impressed by her apparent openness; for him, this bodes well for the talks ahead. Behind him, a few colleagues wince at his indiscretion, but are relieved when it appears he has got away with it. Behind her, Badriʹs male colleagues from Iran are shocked. Some are disgusted. For women to touch unfamiliar men is neither customary nor appropriate in their culture. But Badri has studied and worked in the States for several years and, though she finds such incidents uncomfortable, she has learned to ‘switch’ between styles of working when required. Plus, for her, the priorities of her employer mean that nurturing a solid, trusting relationship with their German partner is of paramount importance. Sean and Nils are elected employee representatives sitting on the European Works Council of the Anglo–Dutch steel firm, Corus, for whom they both work. Nils is Dutch and works in his native Holland; Sean is Irish but works in a smelting works in England. They are both union members (though in different unions), both Corus employees, and both engineers.

Measuring trust in organizational contexts: An overview of survey-based measures

The organizational trust literature has burgeoned over the past two decades. Whilst this expanding research has produced increasing coherence on the conceptualization and definition of trust, the same cannot be said about the psychometric measurement of trust. Rather, the measurement of trust has received scant attention, resulting in a highly fragmented and idiosyncratic use of trust measures, and a confusing array of instruments that vary widely in construct validity and the number and type of trust dimensions (McEvily and Tortoriello, 2011).

Subcortical brain structure and suicidal behaviour in major depressive disorder: a meta-analysis from the ENIGMA-MDD working group

The aetiology of suicidal behaviour is complex, and knowledge about its neurobiological mechanisms is limited. Neuroimaging methods provide a noninvasive approach to explore the neural correlates of suicide vulnerability in vivo. The ENIGMA-MDD Working Group is an international collaboration evaluating neuroimaging and clinical data from thousands of individuals collected by research groups from around the world. Here we present analyses in a subset sample (n=3097) for whom suicidality data were available. Prevalence of suicidal symptoms among major depressive disorder (MDD) cases ranged between 29 and 69% across cohorts. We compared mean subcortical grey matter volumes, lateral ventricle volumes and total intracranial volume (ICV) in MDD patients with suicidal symptoms (N=451) vs healthy controls (N=1996) or MDD patients with no suicidal symptoms (N=650). MDD patients reporting suicidal plans or attempts showed a smaller ICV (P=4.12 × 10−3) or a 2.87% smaller volume compared with controls (Cohen’s d=−0.284). In addition, we observed a nonsignificant trend in which MDD cases with suicidal symptoms had smaller subcortical volumes and larger ventricular volumes compared with controls. Finally, no significant differences (P=0.28–0.97) were found between MDD patients with and those without suicidal symptoms for any of the brain volume measures. This is by far the largest neuroimaging meta-analysis of suicidal behaviour in MDD to date. Our results did not replicate previous reports of association between subcortical brain structure and suicidality and highlight the need for collecting better-powered imaging samples and using improved suicidality assessment instruments.
