Lay Epistemic Theory: The Motivational,Cognitive, and Social Aspects of Knowledge Formation

We review and integrate three separate research programs emanating from the theory of lay epistemics (Kruglanski, A. W. (1989). Lay Epistemics and Human Knowledge: Cognitive and Motivational Bases. New York: Plenum). The need for cognitive closure is an epistemic motivation that propels knowledge formation and has widely ramifying consequences for individual, interpersonal, and group phenomena. The unimodel investigates the process of new knowledge formation from the ‘information given.’ The work on epistemic authority highlights the centrality of social source effects, including the self as a source, in human epistemic behavior. These three research programs examine facets of epistemic behavior that function interdependently to produce the knowledge that guides individual and social functioning.     

Effect of circadian rhythms on retrieval-induced forgetting

This study investigated the effects of natural circadian rhythms on retrieval-induced forgetting (RIF; Anderson et al. in J Exp Psychol Learn Mem Cogn 20:1063–1087, 1994). Individuals tested at optimal times (i.e., morning persons tested in the morning and evening persons tested in the evening) showed a significantly greater RIF effect than individuals tested at non-optimal times (i.e., morning persons tested in the evening and evening persons tested in the morning). Thus, the limited quantity of resources available to allocate in the inhibitory activity during non-optimal times produced a significant decrement in RIF. These findings are compatible with the inhibitory account of RIF and with the notion of a resource-demanding process underlying this memory phenomenon.     

Regulatory mode orientations and well‐being in an organizational setting: the differential mediating roles of workaholism and work engagement

This paper examines the relationships between two independent regulatory mode orientations, locomotion and assessment, and well‐being in organizational contexts. Results from a sample of 320 employees revealed that locomotion was negatively associated with burnout and psychological strain whereas assessment was positively associated with burnout and strain. The effects of locomotion and assessment on burnout and strain were mediated by workaholism and work engagement. Both locomotion and assessment predicted greater workaholism; however, locomotion was positively associated whereas assessment was negatively associated with work engagement. In turn, workaholism predicted greater burnout and strain, and work engagement predicted less burnout and strain. Implications for employee health and organizational success are discussed.     

Beyond need satisfaction: Empowering and accepting messages from third parties ineffectively restore trust and consequent reconciliation

According to the Needs‐Based Model, reconciliation requires the restoration of victims' sense of power and perpetrators' moral image, which can be achieved through the exchange of empowering and accepting messages. In two role‐playing experiments, we extended the model by examining the role of message source, the other conflict party versus a neutral third party, in facilitating reconciliation. Focusing on transgressions between apartment roommates, Study 1 found that regardless of message source, empowering messages restored victims' sense of power, and accepting messages restored perpetrators' moral image. Yet, messages from the other conflict party restored victims' and perpetrators' trust in each other more effectively than messages from third parties. Multiple mediation analyses revealed that both need satisfaction (restoring victims' sense of power and perpetrators' moral image) and trust building were critical for reconciliation. Replicating these findings in a context of transgressions between workplace colleagues, Study 2 further revealed that messages from third parties restored perpetrators' moral image only in the eyes of the third party (but not in the eyes of the victim), leading to a negative indirect effect on perpetrators' reconciliation tendencies. Theoretical implications for the modification of the Needs‐Based Model and practical implications for the limits of third parties' interventions to promote interpersonal reconciliation are discussed.

Bending perception to desire: Effects of task demands,motivation, and cognitive resources

Determinants of motivated judgments were examined in this research. Three experiments investigated how dominant motivation, biasing difficulty and mental resources combine to produce motivationally congruent judgments. Studies 1 and 2 showed that where a biasing motivation is dominant the presence of resources can augment a motivational bias in judgment. Study 3 replicated that result and showed that resources contribute to the formation of biased judgments only where biasing is difficult to accomplish, but not where it is relatively easy to accomplish. In addition, Study 3 showed that where the accuracy motivation is dominant and biasing is the easy default, unbiased judgments will occur only in the presence (vs. absence) of resources. In contrast, where unbiased judgments are easy to come by, such judgments occur irrespective of resources.     

Event components in autobiographical memories

Autobiographical memories contain activity, location, temporal, and participant information (Lancaster & Barsalou, 1997). Our study analysed potential dominance of activity information in autobiographical memories. The results indicated stability in dominance of the activity component, defined as similar occurrence in first and subsequent reports, and a relative absence of the temporal component in these verbal reports. Activity dominance also occurred when activity information from the verbal reports was used as a retrieval cue for a subsequent report. Temporal information demonstrated a greater lack of facilitation as a retrieval cue. These findings can be explained from the perspective of embodied cognition in which underlying perceptual states that contain activity, location, and other participant information are reconstructed during retrieval, whereas temporal information, as a more abstract component, is not.     

An experimental test of the relationship between voice intonation and persuasion in the domain of health

Objective: In the process of behaviour change, intonation of speech is an important aspect that may influence persuasion when auditory messages are used. In two experiments, we tested to what extent different levels of intonation are related to persuasion and whether for some recipients the threat posed by the message information might become too strong to face.

Design: In Study 1, 130 respondents listened to a health message with either a low, moderate or high level of intonation. In Study 2 (N?=?143), the same manipulations of intonation were applied but half of the respondents were affirmed before they listened to the persuasive message. Intention to increase fruit and vegetable intake was used as a dependent variable.

Results: Both studies showed that high intonation led to a significant drop in intention among respondents who perceived their own health as good. After self-affirmation, persuasion was increased.

Conclusion: A high level of intonation seems to induce self-regulatory defences in people who do not see the necessity to change their health behaviour, whereas people with poor perceived health might perceive potential to change. The use of a normal level of intonation in auditory health messages is recommended.
