Terror in time: extending culturomics to address basic terror management mechanisms

Building on Google's efforts to scan millions of books, this article introduces methodology using a database of annual word frequencies of the 40,000 most frequently occurring words in the American literature between 1800 and 2009. The current paper uses this methodology to replicate and identify terror management processes in historical context. Variation in frequencies of word usage of constructs relevant to terror management theory (e.g. death, worldview, self-esteem, relationships) are investigated over a time period of 209 years. Study 1 corroborated previous TMT findings and demonstrated that word use of constructs related to death and of constructs related to patriotism and romantic relationships significantly co-vary over time. Study 2 showed that the use of the word “death” most strongly co-varies over time with the use of medical constructs, but also co-varies with the use of constructs related to violence, relationships, religion, positive sentiment, and negative sentiment. Study 3 found that a change in the use of death related words is associated with an increase in the use of fear related words, but not in anxiety related words. Results indicate that the described methodology generates valuable insights regarding terror management theory and provide new perspectives for theoretical advances.     

Editorial: Harmful or helpful to learning? The impact of seductive details on learning and instruction

Most previous research found negative effects on learning outcomes when interesting but irrelevant information (i.e., seductive details) is added to an instruction. To what degree such effects are bound to specific conditions is in the focus of this special issue. Specifically, 11 empirical studies are reported within this special issue. They all address the topic of seductive details in learning and instruction by focusing either on cognitive moderators (e.g., working memory capacity and current beliefs) or on noncognitive moderators (e.g., arousal and affect) of the seductive details effect. Taken together, results from the empirical studies hint towards new moderators and suggest that the negative effects of seductive details on learning outcomes may be smaller than expected based on previous research.     

You’re looking for what? Comparing search for familiar,nameable objects to search for unfamiliar,novel objects

Searching for items in one’s environment often includes considerable reliance on semantic knowledge. The present study examines the importance of semantic information in visual and memory search, especially with respect to whether the items reside in long-term or working memory. In Experiment 1, participants engaged in hybrid visual memory search for items that were either highly familiar or novel. Importantly, the relatively large number of targets in this hybrid search task necessitated that targets be stored in some form of long-term memory. We found that search for familiar objects was more efficient than search for novel objects. In Experiment 2, we investigated search for familiar versus novel objects when the number of targets was low enough to be stored in working memory. We also manipulated how often participants in Experiment 2 were required to update their target (every trial vs. every block) in order to control for target templates that were stored in long-term memory as a result of repeated exposure over trials. We found no differences in search efficiency for familiar versus novel objects when templates were stored in working memory. Our results suggest that while semantic information may provide additional individuating features that are useful for object recognition in hybrid search, this information could be irrelevant or even distracting when searching for targets stored in working memory.     

Bilingual toddlers’ comprehension of mixed sentences is asymmetrical across their two languages

In bilingual language environments, infants and toddlers listen to two separate languages during the same key years that monolingual children listen to just one and bilinguals rarely learn each of their two languages at the same rate. Learning to understand language requires them to cope with challenges not found in monolingual input, notably the use of two languages within the same utterance (e.g., Do you like the perro? or ¿Te gusta el doggy?). For bilinguals of all ages, switching between two languages can reduce the efficiency in real‐time language processing. But language switching is a dynamic phenomenon in bilingual environments, presenting the young learner with many junctures where comprehension can be derailed or even supported. In this study, we tested 20 Spanish–English bilingual toddlers (18‐ to 30‐months) who varied substantially in language dominance. Toddlers’ eye movements were monitored as they looked at familiar objects and listened to single‐language and mixed‐language sentences in both of their languages. We found asymmetrical switch costs when toddlers were tested in their dominant versus non‐dominant language, and critically, they benefited from hearing nouns produced in their dominant language, independent of switching. While bilingualism does present unique challenges, our results suggest a united picture of early monolingual and bilingual learning. Just like monolinguals, experience shapes bilingual toddlers’ word knowledge, and with more robust representations, toddlers are better able to recognize words in diverse sentences.     

Unique contribution of semantic representations to immediate memory: an individual-differences approach

Studies have reported dissociations between the contributions of semantic and phonological representations to immediate remembering, found through experimental manipulations as well as specific clinical cases. Also, some studies based on the analysis of individual differences reported that a semantic cued recall task has a variance unshared with the immediate memory tasks which tap the contribution of phonological representations. However, another study suggested that cued recall performance could reflect a wider ability to cluster information by category. Furthermore, no studies of individual differences have investigated the unique semantic contribution in the visual domain. Therefore, the present study used specific immediate recognition memory tasks that have been used to investigate the semantic contribution in the verbal and visual domains. The results demonstrate the unshared variance that reflects the semantic contribution in both the verbal and the visual domain, and some commonality in these variances across the domains.     

Essentialism in Social Representations of Citizenship: An Analysis of Greeks' and Migrants' Discourse

Following a Social Representations approach, the article examines the representations of citizenship held by both migrants and Greek citizens in Greece after the announcement of a heavily debated citizenship legislation. Essentialism, a way of representing social categories as holding an underlying essence that determines their characteristics, was used as an analytical tool to understand the inclusive or exclusive function of representations of citizenship towards migrants. Findings showed that Greeks construct representations based on ethnic, civic, and cultural ideas, while migrants construct representation of citizenship based on civic and cultural ideas. Essentialism was a way of constructing ethnic and cultural representations of citizenship and functioned in both exclusive and inclusive ways, but assimilatory terms accordingly. Civic and cultural representations of citizenship were constructed in nonessentialist ways and functioned in inclusive ways. However, from Greeks' perspective, civic inclusion was conditioned upon an often‐questioned legality of migrants and upon cultural assimilation terms. Studying both the content and the essentialist/nonessentialist formulation of representations of citizenship is an important tool in understanding the politics of inclusion and exclusion of citizens in the social arena.

‘It was all intertwined’: Illness representations and self-management in patients with cancer and anxiety/depression

Objective: Cancer and anxiety/depression frequently co-occur, leading to poorer outcomes for these illnesses. However, the majority of existing research investigates how participants view single illnesses alone. This study aimed to explore the content of individuals’ multimorbid representations and how these relate to their coping behaviours and self-management strategies for cancer and anxiety/depression.

Design: A semi-structured qualitative research design with theoretical thematic analysis.

Main Outcome Measures: Multimorbid illness representations, coping behaviours, and self-management strategies.

Results: In interviews with 21 participants multimorbid representations varied, three participants viewed cancer and anxiety/depression as unrelated, five participants were uncertain about the relationship between cancer and anxiety/depression, and the majority of participants perceived cancer and anxiety/depression as related. This third group of participants often described relationships as causal, with representations having both positive and negative influences on coping behaviours and self-management strategies. Representations were shown to change over the course of the cancer experience, with fear of cancer recurrence and the influence of participants’ most challenging illness also discussed.

Conclusions: People hold multimorbid illness representations that can influence self-management. An awareness of these representations by researchers, health professionals, and patients is important for the creation of future interventions that aim to improve and maintain patient wellbeing.     

Usage of semantic representations in recognition memory

Meanings of words facilitate false acceptance as well as correct rejection of lures in recognition memory tests, depending on the experimental context. This suggests that semantic representations are both directly and indirectly (i.e., mediated by perceptual representations) used in remembering. Studies using memory conjunction errors (MCEs) paradigms, in which the lures consist of component parts of studied words, have reported semantic facilitation of rejection of the lures. However, attending to components of the lures could potentially cause this. Therefore, we investigated whether semantic overlap of lures facilitates MCEs using Japanese Kanji words in which a whole-word image is more concerned in reading. Experiments demonstrated semantic facilitation of MCEs in a delayed recognition test (Experiment 1), and in immediate recognition tests in which participants were prevented from using phonological or orthographic representations (Experiment 2), and the salient effect on individuals with high semantic memory capacities (Experiment 3). Additionally, analysis of the receiver operating characteristic suggested that this effect is attributed to familiarity-based memory judgement and phantom recollection. These findings indicate that semantic representations can be directly used in remembering, even when perceptual representations of studied words are available.     

'The double identity' of Taiwanese Chinese: A dilemma of politics and culture rooted in history

The 'double identity' of Taiwanese as both Chinese and Taiwanese identity was measured among both general and student samples using categorical and continuous measures. As predicted, Mingnan (native province) Taiwanese were higher in Taiwanese identity whereas outside-province Taiwanese were higher in Chinese identity. Both groups shared similar representations of the history of Taiwan, but evaluations of leaders followed patterns of in-group favoritism. These representations of history were used to predict and find zero correlations between Chinese and Taiwanese identity. Taiwanese and Chinese identities were mutually compatible in cultural domains, and mediated the effect of demographic group. However, in issues concerning politicized allocation decisions (and language), Taiwanese and Chinese identity worked in opposite directions, and demographic group (and a critical evaluation of an historical leader) were significant even after controlling for identity. Implications for social identity theory, realistic group conflict theory, and the cross-straits relationship are discussed.
