A deeper analysis of the spacing effect after “deep” encoding

The most common encoding strategies used by participants in word list studies include rehearsal and using the story mnemonic. Previous studies have suggested that with a rote-rehearsal strategy, mixed lists lead people to borrow rehearsal time from massed items and to give it to spaced items. Using rehearse-aloud methodologies, we demonstrated in Experiment 1 that the borrowing effect does not occur in the story mnemonic. However, the rates of rehearsal of individual items provided a good prediction of their subsequent recall rates, with spaced items being rehearsed more often in both mixed and pure lists. In Experiment 2, we demonstrated that creating "story links" between items enhanced recall, but it did not affect the magnitude of the spacing effect. These results suggest that a massed-item deficit in encoding may underlie the spacing effect in the story mnemonic.

Empathy in intimate relationships: The role of positive illusions

Previous studies have shown empathy to be an important aspect of a high quality intimate relationship. Likewise, positive illusions about a partner's characteristics have been shown to contribute to relationship quality. The present study connects these issues by examining the degree to which individuals hold positive illusions about a partner's level of empathy, and the extent to which these positive illusions are related to relationship quality and adjustment in a sample of 55 couples. Results showed that positive illusions concerning a partner's level of empathy were only held by women. In addition, people's evaluation of relationship quality and adjustment was consistently related to both their own and their partner's positive empathy illusions. Finally, an interaction effect was found between participant sex and the partner effect of positive empathy illusions: the illusions held by the partner (only for men) were related to relationship quality. Results and implications for theory and relationship counseling are discussed.     

Does remembering past ingroup harmdoing promote postwar cross‐group contact? Insights from a field‐experiment in Liberia

In the aftermath of the Liberian civil wars, we investigated whether it is possible to systematically influence how people construe their group's role during the conflict and how this affects intergroup emotions and behavioral intentions. In a field experiment, 146 participants were randomly assigned to think about incidents of violence during the war that were either committed by fellow ingroup members (perpetrator‐focus) or against fellow ingroup members (victim‐focus). Adopting a perpetrator‐focus led to greater willingness to engage in cross‐group contact, greater need for acceptance, and greater intergroup empathy. The focus manipulation did not affect participants' need for empowerment. Key message: Appraising the ingroup as “victim” or “perpetrator” after conflicts with reciprocal harmdoing is largely a matter of psychological construction. A promising avenue for promoting positive cross‐group contact consists in widening the ingroup's victim role by also remembering the harm that the ingroup inflicted upon others. This amplifies the need of acceptance, which leads to greater intergroup empathy and greater willingness to engage in cross‐group contact. Copyright © 2013 John Wiley & Sons, Ltd.     

Aging and Situation Model Updating

The aim of this study was to investigate age differences in narrative comprehension and memory, with a focus on the updating of situation models during comprehension. While there are large effects of aging on memory for propositional textbase information, there is very little evidence that older adults have difficulty at the situation model level. Because described events are often dynamic, a comprehender must consistently update their situation model to make it consistent with the new information. The current experiments investigated whether there are any age differences associated with the ability to update a situation model along the spatial and temporal dimensions. Although updating effects were observed, they were largely not influenced by age. The relation of these findings to an understanding of older adults’ language comprehension and memory performance is discussed.     

Effects of processing style on responsiveness to affective stimuli and processing fluency

In the present study, we provide direct evidence for effects of global versus local processing on responsiveness to and reliance on affective information in judgement and decision-making. Results of Experiments 1 and 2 showed an increased responsiveness to affective stimuli among participants in a global processing mode. Experiment 3 showed similar effects for processing fluency; participants adopting a global processing style showed an increased reliance on fluency. Experiment 4 replicated our findings in a more mundane judgement task in which participants judged apartments. We discuss our findings in relation to the distinction between intuitive versus deliberative modes of thinking.     

A Bayesian psychophysical model for angular variables

Bayesian theories of perception provide a link between observed response distributions and theoretical constructs from Bayesian decision theory. Using Bayesian psychophysics we derive response distributions for two cases, one based on a normal distribution and one on a von Mises distribution for angular variables. Interestingly, where the theoretical response distribution is always unimodal in the case of normal distributions, it can become bimodal in the angular setting in the case when prior and likelihood are about equally strong.     

Disengagement beliefs in smokers: Do they influence the effects of a tailored persuasive message advocating smoking cessation?

Disengagement beliefs function to reduce cognitive dissonance and a number of predictions with regard to disengagement beliefs have been tested and verified. However, the influence of disengagement beliefs on persuasion has not been studied yet. In a field-experiment, 254 smokers were randomly assigned to a persuasive message condition or a no-information control condition. First, it was assessed to what extent disengagement beliefs influenced persuasion. In smokers with low adherence to disengagement beliefs, quitting activity (attempting to quit) in the control condition was high, but this was not further increased by persuasive information on the negative outcomes of smoking. In contrast, smokers who strongly adhered to disengagement beliefs showed low quitting activity in the control condition, but significantly more quitting activity when they received the persuasive message. Second, it was studied what smokers do when they experience negative affect caused by the persuasive message. The results show that in smokers who strongly adhered to disengagement beliefs, negative affect was associated with less quitting activity. Although these results show that quitting activity as assessed at 2 and 8 months follow-ups was influenced by disengagement beliefs, point prevalence seven-day quitting was not. This study shows that adherence to disengagement beliefs is a relevant individual difference in understanding effects of smoking cessation interventions.     

When status differences are illegitimate,groups' needs diverge: Testing the needs‐based model of reconciliation in contexts of status inequality

The present paper extends the needs‐based model of reconciliation to contexts marked by status inequalities rather than by overt intergroup aggression. Specifically, we investigated whether and when members of high‐status versus low‐status groups experience divergent socio‐emotional needs vis‐à‐vis members of the respective other status group. Building on research informed by social identity theory, we hypothesized that the groups' different positions in the social hierarchy only translate into divergent needs when the status differences are perceived as illegitimate. In Study 1 (N = 130), we tested this prediction by manipulating status and perceived legitimacy of status differences in a setting with artificially created groups. Results confirmed that the need to be socially accepted by members of the other status group was stronger in high‐status compared with low‐status group members but, as expected, only when the status differences were perceived to be illegitimate. Also as predicted, the need to be empowered by the other status group was stronger in low‐status compared with high‐status group members, again only under conditions of illegitimate status differences. Study 2 (N = 169) further corroborated our perspective by replicating these findings in a naturalistic intergroup context. Implications for the role of legitimacy perceptions in determining differential socio‐emotional needs and for the promotion of sustainable social change are discussed.

Jealousy in response to online and offline infidelity: the role of sex and sexual orientation

The goal of the present study was to examine the emotional content and intensity of jealousy in response to different types of infidelity (both online and offline unfaithful partner behaviors) among Dutch heterosexuals (n = 191) and homosexuals (n = 121). Based on previous research (Dijkstra, Barelds & Groothof, 2010), participants were presented with ten jealousy‐evoking situations following which the intensity of two different emotional aspects of jealousy was assessed (betrayal/anger and threat). Results showed that scenarios describing a partner having sex with someone else or falling in love with someone else primarily evoked betrayal/anger‐related jealousy, whereas scenarios describing an emotional connection between a partner and someone else primarily evoked threat‐related jealousy. In addition, women experienced more jealousy than men in response to scenarios in which a partner engaged in potentially extra‐dyadic online (but not offline) behaviors. Finally, compared to same‐sex heterosexuals, homosexuals, both male and female, responded with less intense jealousy to scenarios describing a partner having sex with someone else. Implications for the treatment of (internet) infidelity are discussed.
