Be aware of the rifle but do not forget the stench: differential effects of fear and disgust on lexical processing and memory

The aim of this study was to investigate the role of discrete emotions in lexical processing and memory, focusing on disgust and fear. We compared neutral words to disgust-related words and fear-related words in three experiments. In Experiments 1 and 2, participants performed a lexical decision task (LDT), and in Experiment 3 an affective categorisation task. These tasks were followed by an unexpected memory task. The results of the LDT experiments showed slower reaction times for both types of negative words with respect to neutral words, plus a higher percentage of errors, this being more consistent for fear-related words (Experiments 1 and 2) than for disgust-related words (Experiment 2). Furthermore, only disgusting words exhibited a higher recall accuracy than neutral words in the memory task. Moreover, the advantage in memory for disgusting words disappeared when participants carried out an affective categorisation task during encoding (Experiment 3), suggesting that the superiority in memory for disgusting words observed in Experiments 1 and 2 could be due to greater elaborative processing. Taken together, these findings point to the relevance of discrete emotions in explaining the effects of the emotional content on lexical processing and memory.     

The use of messages in altering risky gambling behavior in experienced gamblers

The present study was an experimental analogue that examined the relationship between gambling-related irrational beliefs and risky gambling behavior. Eighty high-frequency gamblers were randomly assigned to four conditions and played a chance-based computer game in a laboratory setting. Depending on the condition, during the game a pop-up screen repeatedly displayed either accurate or inaccurate messages concerning the game, neutral messages, or no messages. Consistent with a cognitive-behavioral model of gambling, accurate messages that correctly described the random contingencies governing the game decreased risky gambling behavior. Contrary to predictions, inaccurate messages designed to mimic gamblers' irrational beliefs about their abilities to influence chance events did not lead to more risky gambling behavior than exposure to neutral or no messages. Participants in the latter three conditions did not differ significantly from one another and all showed riskier gambling behavior than participants in the accurate message condition. The results suggest that harm minimization strategies that help individuals maintain a rational perspective while gambling may protect them from unreasonable risk-taking.     

Schema bias in source monitoring varies with encoding conditions: Support for a probability-matching account

Two experiments examined reliance on schematic knowledge in source monitoring. Based on a probability-matching account of source guessing, a schema bias will only emerge if participants do not have a representation of the source-item contingency in the study list, or if the perceived contingency is consistent with schematic expectations. Thus, the account predicts that encoding conditions that affect contingency detection also affect schema bias. In Experiment 1, the schema bias commonly found when schematic information about the sources is not provided before encoding was diminished by an intentional source-memory instruction. In Experiment 2, the depth of processing of schema-consistent and schema-inconsistent source-item pairings was manipulated. Participants consequently overestimated the occurrence of the pairing type they processed in a deep manner, and their source guessing reflected this biased contingency perception. Results support the probability-matching account of source guessing. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Perceptual experience shapes our ability to categorize faces by national origin: A new other-race effect

People are better at recognizing own-race than other-race faces. This other-race effect has been argued to be the result of perceptual expertise, whereby face-specific perceptual mechanisms are tuned through experience. We designed new tasks to determine whether other-race effects extend to categorizing faces by national origin. We began by selecting sets of face stimuli for these tasks that are typical in appearance for each of six nations (three Caucasian, three Asian) according to people from those nations (Study 1). Caucasian and Asian participants then categorized these faces by national origin (Study 2). Own-race faces were categorized more accurately than other-race faces. In contrast, Asian American participants, with more extensive other-race experience than the first Asian group, categorized other-race faces better than own-race faces, demonstrating a reversal of the other-race effect. Therefore, other-race effects extend to the ability to categorize faces by national origin, but only if participants have greater perceptual experience with own-race, than other-race faces. Study 3 ruled out non-perceptual accounts by showing that Caucasian and Asian faces were sorted more accurately by own-race than other-race participants, even in a sorting task without any explicit labelling required. Together, our results demonstrate a new other-race effect in sensitivity to national origin of faces that is linked to perceptual expertise.     

Motivated information processing, strategic choice, and the quality of negotiated agreement

The authors tested a motivated information-processing model of negotiation: To reach high joint outcomes, negotiators need a deep understanding of the task, which requires them to exchange information and to process new information systematically. All this depends on social motivation, epistemic motivation (EM), and their interaction. Indeed, when EM (manipulated by holding negotiators process accountability or not) was high rather than low and prosocial rather than proself, negotiators recall more cooperative than competitive tactics (Experiment 1), had more trust, and reached higher joint outcomes (Experiment 2). Experiment 3 showed that under high EM, negotiators who received cooperative, rather than competitive, tactics reached higher joint outcomes because they engaged in more problem solving. Under low EM, negotiators made more concessions and reached low joint outcomes. Implications for negotiation theory and for future work in this area are discussed.     

Effects of instruction on learners’ ability to generate an effective pathway in the method of loci

One of the most effective mnemonic techniques is the well-known method of loci. Learning and retention, especially of sequentially ordered information, is facilitated by this technique which involves mentally combining salient loci on a well-known path with the material to be learned. There are several variants of this technique that differ in the kind of path that is suggested to the user and it is implicitly assumed that these variants are comparable in effectiveness. The experiments reported in this study were designed to test this assumption. The data of two experiments show that participants who are instructed to generate and apply loci on a route to their work recall significantly more items in a memory test than participants who are instructed to generate and apply loci on a route in their house. These results have practical implications for the instruction and application of the method of loci.     

Outcome interdependence shapes the effects of prevention focus on team processes and performance

Although the effects of regulatory focus on individual-level performance have often been studied, relatively little is yet known about team-level effects. Filling this void, we integrate the notion that promotion-focused individuals are concerned with progress and achievement, whereas prevention-focused individuals are concerned with security and vigilance, with the insight that team processes and performance depend on outcome interdependence (individual versus team rewards). The hypothesis that prevention-focused teams react more strongly than promotion-focused teams to differences in outcome interdependence was tested among 50 teams performing an interactive command-and-control simulation. Regulatory focus and outcome interdependence were both manipulated. The results showed that prevention-focused teams working for team rather than individual rewards reported higher work engagement and less error intolerance, coordinated more effectively, and performed better. Promotion-focused teams were not influenced by outcome interdependence. We discuss the implications of our results for theory and effective team management.     

Achievement emotions in elementary,middle, and high school: How do students feel about specific contexts in terms of settings and subject‐domains?

The present work investigates students' representation of achievement emotions, focusing in context‐specific situations in terms of settings and subject‐domains, as a function of grade level. We involved 527 fourth‐, seventh‐, and eleventh‐graders, who evaluated ten discrete emotions through questionnaires, with reference to verbal language and mathematics, and different settings (class, homework, tests). Confirmatory multitrait‐multimethod analyses indicated higher salience of subject‐domains rather than settings for all the emotions; however, complexity of reality was best explained when also settings were accounted for. Analyses of variance revealed higher intensity of positive emotions for younger students, and the opposite pattern for older students; significant differences for most of the emotions based on the evaluative nature of settings, moderated by class levels; more intense positive emotions for mathematics and more intense negative emotions for Italian. Results are discussed considering their theoretical and applied relevance, corroborating previous literature on domain‐specificity.
