Disentangling the Interrelations Between Hopelessness,Loneliness, and Suicidal Ideation

We attempted to disentangle the interrelations between hopelessness, loneliness, and suicidal ideation, by comparing two conceptually driven models of their relationships, prospectively among 234 undergraduates, using a series of multiple regression/correlation equations. Model 1 framed loneliness as a risk factor for future suicidally that operates via its influence on hopelessness (the mediational view). Model 2 viewed hopelessness as a source variable that is predictive of both loneliness and suicidally, and postulated no relation between loneliness and suicidality beyond hopelessness. Model 2 received support, whereas Model 1 did not. We discuss the implications of our findings for the nomological status of hopelessness and loneliness as correlates of suicidality, and for exploration of the structural interrelations of suicide-related variables in general.     

What fair procedures say about me: Self-construals and reactions to procedural fairness

Past research has revealed both positive and negative reactions when people receive unfavorable outcomes via fair decision-making procedures. In three laboratory experiments, we reconcile these findings by considering the role of people’s self-identity. Our results suggest that the more that people base their self-identity on their relationships with others—as indexed by a strong interdependent self-construal—the more positively they react to an unfavorable outcome following from fair procedures. Conversely, the more that people base their self-identity on achievement—as indexed by a strong independent self-construal—the more negatively they react to an unfavorable outcome following from fair procedures. Moreover, these results were stronger when the situation primed interdependence and independence, respectively. Our research indicates that people interpret procedural fairness information in a manner that is consistent with defining aspects of the self.     

Pressure to cooperate: Is positive reward interdependence really needed in cooperative learning?

Background. Despite extensive research on cooperative learning, the debate regarding whether or not its effectiveness depends on positive reward interdependence has not yet found clear evidence. Aims. We tested the hypothesis that positive reward interdependence, as compared to reward independence, enhances cooperative learning only if learners work on a ‘routine task’; if the learners work on a ‘true group task’, positive reward interdependence induces the same level of learning as reward independence. Sample. The study involved 62 psychology students during regular workshops. Method. Students worked on two psychology texts in cooperative dyads for three sessions. The type of task was manipulated through resource interdependence: students worked on either identical (routine task) or complementary (true group task) information. Students expected to be assessed with a Multiple Choice Test (MCT) on the two texts. The MCT assessment type was introduced according to two reward interdependence conditions, either individual (reward independence) or common (positive reward interdependence). A follow‐up individual test took place 4 weeks after the third session of dyadic work to examine individual learning. Results. The predicted interaction between the two types of interdependence was significant, indicating that students learned more with positive reward interdependence than with reward independence when they worked on identical information (routine task), whereas students who worked on complementary information (group task) learned the same with or without reward interdependence. Conclusions. This experiment sheds light on the conditions under which positive reward interdependence enhances cooperative learning, and suggests that creating a real group task allows to avoid the need for positive reward interdependence.     

A study of semantic and syntactic processing in monolinguals and fluent early bilinguals

The present study consists of two reaction-time experiments administered in English. These experiments were designed to compare semantic and syntactic processing in English monolinguals and fluent early French-English bilinguals. Results of both experiments revealed that the bilinguals did not function as the English monolinguals did. That is, their reaction times were slower and they made twice as many errors in response to certain sentences. These findings are especially important for two reasons: (1) The bilinguals were all highly fluent, and in most cases dominant, in English, and (2) the bilinguals exhibited systematic differences in two different linguistic components (the semantic and the syntactic). The results are viewed as evidence of the interdependence of the bilinguals' languages. Some note is made of individual patterns of response, and two interpretations of linguistic interdependence are provided.     

Will we be working together again? The impact of future interdependence on group members' task motivation

The extent to which group members contribute effort efficiently, i.e. to the extent that their efforts add to the group product, or equally to their fellow worker is investigated as a function of group members' expectations about future interdependence. An experimental set‐up was employed in which (1) participants were able to determine what would be an efficient and what would be an equal amount of effort to exert, and (2) in which efficiency and equality required different levels of effort: Participants worked on a physical motor‐production task and expected to work with a partner twice (continued interdependence) or only on the first task (no continued interdependence). Before working on the first task, they received information about their relative task ability (high versus low) and information about their partner's effort expenditure (high versus low). It is argued and demonstrated that group members expecting continued interdependence are likely to equal their fellow worker's effort expenditure, whereas group members expecting no continued interdependence are likely to exert effort efficiently. The results are discussed from various theoretical perspectives. Copyright © 2001 John Wiley & Sons, Ltd.     

Complementarity of Information and Quality of Relationship in Cooperative Learning

The effects of resource in(ter)dependence and quality of relationship with the partner on performance were studied during three sessions of cooperative dyadic work in order to examine the conditions under which cooperative learning can be more beneficial. This study was designed to test a hypothesis favouring the superiority of independence of resources (discussing identical information) against a hypothesis favouring the superiority of interdependence of resources (sharing complementary information). In each session, 64 students worked in dyads on two texts. Two roles were defined: summarizer and listener. Results showed that, though direct performance was higher when students discussed identical information, the quality and generality of information recalled a few months later did not differ between the two conditions. In the interdependence condition, listeners displayed poorer levels for direct performance. Participants were then dichotomized on the basis of their perceived quality of their relationship with the partner. With respect to direct performance, a more positive relationship allowed listeners in the interdependence condition to perform as well as summarizers, while a less positive relationship was detrimental for listeners. Conversely, as for recall, listeners in the interdependence condition who perceived a more positive relationship performed more poorly than summarizers, while listeners who perceived a less positive relationship performed as well as summarizers. When students shared identical information, neither roles nor quality of relationship affected recall. Results are discussed in terms of degree of partners' dependence and potential effects of socio-cognitive conflict (Doise & Mugny, 1984). This revised version was published online in August 2006 with corrections to the Cover Date.     

Getting social in selection: How social networking website content is perceived and used in hiring

The use of social networking websites (SNWs) during employee selection is gaining popularity in organizations. Using a foundation that integrates identity and situational strength theories, we develop a conceptual framework that differentiates SNW information from information gathered through traditional selection procedures, and distinguishes between SNW types. Research questions and hypotheses are tested using a survey of 291 hiring professionals. Results indicate that SNW content is considered useful and is regularly utilized during hiring. Some SNW content is viewed positively (e.g., information supporting qualifications), while other information leads to negative perceptions (e.g., discriminatory comments). Finally, results support a differentiation between personal and professional SNW, as the kind of information sought and the effectiveness of assessing various work‐related constructs differs between these SNW categories.     

Eyewitness memory for arousing events: putting things into context

If attention is focused on central details at high levels of arousal, memory for peripheral details should be diminished (Easterbrook, 1959 ). If this is the case, contextual reinstatement (CR) procedures should not enhance memory because these procedures specifically use peripheral information to cue memory. The present experiment tested how arousal influenced eyewitness memory for an event and how it interacts with CR procedures. Participants first viewed one of three series of slides (neutral, arousal, or unusual/control). Memory for central and peripheral details was tested via photo lineups and recognition tests. Although CR procedures enhanced recognition memory for non‐arousing and unusual events, they did not affect recognition memory for arousing events. Analyses of the peripheral photo lineup and peripheral recognition test data revealed that CR enhanced the hit rate for the neutral and unusual conditions but not for the arousal condition. Although CR procedures tended to enhance recognition of central information (increasing the hit rate and decreasing the false alarm rate), CR had a smaller enhancement effect in the arousal condition relative to the neutral and unusual conditions. The present experiment also replicates the Christianson and Loftus ( 1991 ) finding that peripheral information is not remembered as well in an arousing event, as compared to memory of neutral and unusual events. The theoretical and applied implications of these results are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Empirical and normative aspects of medical technology assessment. The case of reduced-size liver transplantations with living donors

Medical technology assessment deals with the evaluation of novel or existing health care procedures. This paper addresses the interdependence between factual and normative issues, using the controversies about acceptability and desirability of reduced-size liver transplantations with living donors as example.     

A Description–Experience Gap in Social Interactions: Information about Interdependence and Its Effects on Cooperation

In social interactions, decision makers are often unaware of their interdependence with others, precluding the realization of shared long‐term benefits. In an experiment, pairs of participants played an Iterated Prisoner's Dilemma under various conditions involving differing levels of interdependence information. Each pair was assigned to one of four conditions: “No‐Info” players saw their own actions and outcomes, but were not told that they interacted with another person; “Min‐Info” players knew they interacted with another person but still without seeing the other's actions or outcomes; “Mid‐Info” players discovered the other's actions and outcomes as they were revealed over time; and “Max‐Info” players were also shown a complete payoff matrix mapping actions to outcomes from the outset and throughout the game. With higher levels of interdependence information, we found increased individual cooperation and mutual cooperation, driven by increased reciprocating cooperation (in response to a counterpart's cooperation). Furthermore, joint performance and satisfaction were higher for pairs with more information. We discuss how awareness of interdependence may encourage cooperative behavior in real‐world interactions.

Epistemic emotions: Cognitive underpinnings and relations with metacognitive feelings

The aim of this paper is to review research on epistemic emotions in learning. The emphasis is not only on the cognitive states that give rise to epistemic emotions but also on the dynamics of epistemic emotions in complex learning situations. The interrelations between epistemic emotions and their interactions with affective states and metacognitive experiences are also explored. The position put forth is that epistemic emotions are triggered by cognitive states involving discrepancy, or conflict, between active schemas and incoming information, or gap in one's knowledge. However, each of the epistemic emotions has its specific triggering conditions that differentiate it from the others. Changing conditions during a cognitive endeavor impact the intensity as well as the interrelations between epistemic emotions. Also, there are relations between epistemic emotions and metacognitive experiences such as feeling of difficulty or confidence, albeit not so strong. The implications for future research are discussed.     

Newcomer Information Seeking: Individual and Contextual Influences

This study examined situational and individual influences on the proactive information seeking of newcomers. Task interdependence was expected to be positively related to information seeking, given that it links newcomers to organizational insiders. Newcomers' work related self-efficacy and the physical accessibility of organizational insiders were both predicted to moderate the relationship between task interdependence and information seeking. Usable surveys were completed by 421 co-op students (295 males and 126 females) who had been participating in career-relevant internships for approximately 4.5 weeks. All students were enrolled in an educational programme that rotates students between twelve weeks in class and twelve weeks on internship over a period of five years. Controlling for the number of previous internships and size of work group, results supported the joint moderating effect, with newcomers low on self-efficacy exhibiting greater information seeking when task interdependence and accessibility were high. Applied implications of the results and directions for future research on proactive information seeking and socialization are discussed.

The Impact of Hybrid Dispute‐Resolution Procedures on Constituent Fairness Judgments1

The authors investigated the effects of hybrid third‐party procedures on constituents' procedural and distributive fairness judgments. In Experiment 1, three independent variables were manipulated: third‐party procedure (Med–Arb vs. Arb–Med), concession making during mediation (concessions vs. no concessions), and role (labor vs. management). Participants viewed Med–Arb as fairer than Arb–Med. In Experiment 2, three factors were again manipulated: third‐party procedure (Med–Arb vs. Arb–Med), whether confidential information was revealed during mediation (confidential information revealed vs. not revealed), and arbitration outcomes (winning vs. losing). Results suggest that when no confidential information was revealed, Med–Arb was significantly fairer than Arb–Med, but if confidential information was revealed, then both procedures were equally fair. Results are discussed in terms of procedural design.     

Assessing cross-partner associations in physiological responses via coupled oscillator models

A host of theoretical frameworks suggest associations of physiological signals between two individuals within a romantic relationship. However, few studies have provided empirical evidence of such associations using physiological reactivity from both partners in the dyad. In this study we use measures of respiration and heart rate from romantic partners recorded across three laboratory tasks. We examine the interrelations of each measure between both dyad members using coupled linear oscillators (Boker & Nesselroade, 2002). These models were used to capture oscillations in respiration and heart rate, and to examine interdependence in the physiological signals between both partners. Results show that associations were detectable within all three tasks, with different patterns of coupling within each task. Discussion centers on ways to investigate the synchrony of physiological responses across within relationships, including the promises of and obstacles for doing so.     

Cooperative outcome interdependence, task reflexivity, and team effectiveness: a motivated information processing perspective

A motivated information processing perspective (C. K. W. De Dreu & P. J. D. Carnevale, 2003; see also V. B. Hinsz, R. S. Tindale, & D. A. Vollrath, 1997) was used to predict that perceived cooperative outcome interdependence interacts with team-level reflexivity to predict information sharing, learning, and team effectiveness. A cross-sectional field study involving management and cross-functional teams (N = 46) performing nonroutine, complex tasks corroborated predictions: The more team members perceived cooperative outcome interdependence, the better they shared information, the more they learned and the more effective they were, especially when task reflexivity was high. When task reflexivity was low, no significant relationship was found between cooperative outcome interdependence and team processes and performance. The author concludes that the motivated information processing perspective is valid outside the confines of the laboratory and can be extended toward teamwork in organizations.     

Independence in Information Spaces

Three different types of interdependence between pieces of information, or ??secrets??, are discussed and compared. Two of them, functional dependence and nondeducibility, have been studied and axiomatized before. This article introduces a third type of interdependence and provides a complete and decidable axiomatization of this new relation.     

The role of formal information sharing in key account team effectiveness: does informal control matter and when

Team selling is a useful approach for retaining strategically important accounts in business-to-business markets. For key account sales teams, ensuring adequate access to information about customer needs offers sustainable competitive advantages. However, the internal alignment of market information remains a recurring managerial issue in key account team selling. This study develops a moderated mediation model to identify management strategies that encourage team members' formal information sharing, which in turn improves team effectiveness. Analysis of a multilevel data set comprising 37 fluid key account teams reveals that customer orientation and task interdependence increase formal information sharing among team members. Managers' exercise of professional control strengthens the positive impact that formal information sharing has on team satisfaction. However, the practice has a dysfunctional influence on the positive effect of task interdependence on formal information sharing. Firms with key account management (KAM) programs must decide whether the marginal benefits attained by advocating such professional control outweigh the possible drawbacks.     

The effects of episodic and semantic memory on the identification of sentences masked by white noise

Two studies examine how episodic and semantic memory affect subjects’ abilities to repeat sentences masked by white noise. Subjects first hear a list of 70 sentences that are not masked. Subjects in the framework conditions are told prior to hearing the list that all sentences refer to a contextual framework concerning a deserted island. Subjects in the no-framework groups are not given this information. Subjects in the framework-after condition are given this information only after hearing the list of sentences. Subjects then perform a white-noise identification task. The results indicate that framework subjects are able to identify both old and new framework-related information better than other subjects. Subjects in the no-framework and framework-after conditions identify old information better than control subjects who do not participate in an acquisition phase. Emphasis is placed on the interdependence of episodic and semantic memory, including conditions leading to such interdependence.     

Dependent effect sizes in meta-analysis: incorporating the degree of interdependence

In the present article, a commonly used meta-analytic procedure for handling dependent effect sizes from a single sample was examined, and 2 revised procedures that estimate and incorporate the degree of interdependence were proposed. The authors' simulation results reveal that the commonly used procedure that averages the effect sizes from a single sample (denoted as the samplewise procedure) underestimates the degree of heterogeneity. The proposed variations are less biased than the samplewise procedure in estimating the degree of heterogeneity in most of the situations that we examined. Future directions to further improve the procedures for handling dependent effect sizes from a single sample are discussed.
