Matching between oral inward–outward movements of object names and oral movements associated with denoted objects

In eight experiments, we explored matching effects between oral approach–avoidance movements triggered by word articulation and meaning of the objects the words denoted. Participants (total N?=?1264) rated their liking for words that featured consonantal muscle stricture spots either wandering inwards (e.g., BODIKA, resembling ingestion movements) or outwards (e.g., KODIBA, resembling expectoration movements). These words were labelled as names for various objects. For objects the use of which entails ingestive oral actions (lemonade and mouthwash) inward words were preferred over outward words. For objects that trigger expectorative oral actions (toxical chemical, pill, and bubble gum) this preference was attenuated or even reversed (outward words were liked more than inward). Valence of the denoted object did not play a role in these modulations. Thus, the sagittal direction of mouth movements during silent reading meaningfully interacted with direction of oral actions associated with the denoted objects.     

Erlebnisbasierte und verfälschte Erinnerungen im EEG: Eine Pilotstudie

The present study aims to discriminate true and false memory by examining the EEG activity in a setting as applied as possible to the context of credibility assessment. To achieve this, 19 participants saw a short film about a robbery and had to answer 35 yes-no-questions, 25 of them contained misleading information. In order to distort the participants’ memories suggestive techniques were implemented, e. g. repeated questioning. The comparison of event-related potentials (ERP) of true and false memories reveals a parieto-occipital effect between 350 and 500 ms. This effect is consistent with the parietal old/new effect, which is associated with recollection. At the same time, this finding is in agreement with research associating a transient negativity (N400) with processing of semantic incongruent information.     

Who will win Wimbledon? The recognition heuristic in predicting sports events

Goldstein and Gigerenzer ( 2002 ) described the recognition heuristic as a fast, frugal, and effective decision strategy. However, most studies concerning the recognition heuristic have been conducted in static domains, that is, in domains where it could plausibly be argued that relevant variables stay relatively constant. Yet the question is whether the heuristic would also work in dynamic environments where the quality of the actors rises and falls, such as in sports. We tested performance of the recognition heuristic in a dynamic environment and used it to predict the outcomes of tennis matches in Wimbledon 2003. Recognition data of amateur tennis players and laypeople was used to build recognition rankings. These rankings correlated with official rankings and led to at least as good predictions. Simulations of individual choices showed high recognition validities of both amateurs (0.73) and laypeople (0.67). In a second study the recognition heuristic correctly predicted 90% of actual individual choices. Overall, the recognition heuristic may be effectively generalized to dynamic environments.

Diagnostic Discrimination of Patients with Different OCD Main Symptom Domains from each Other and from Anxious and Depressive Controls

The extent to which the subscales of multidimensional OCD measures accurately distinguish patients with specific OCD main symptom domains from controls at different cutscores has not yet been examined. Diagnostic accuracy of OCD measures usually is determined by comparing the total scores of heterogeneous OCD samples and controls and therefore may underestimate the measures’ discrimination potential. In the current study, subtype-specific diagnostic accuracy and criterion-related validity of the Obsessive-Compulsive Inventory-Revised (OCI-R) subscales were examined in 327 patients with OCD, anxiety, and/or depressive disorders. All subscales demonstrated good to excellent criterion-related validity and diagnostic accuracy for distinguishing patients with specific OCD main symptom domains from controls. As expected, the single OCI-R subscales lead to more accurate diagnostic decisions than the total scale. Thus, the subscale-specific cutscores significantly improve the OCI-R’s utility for subtype-specific treatment planning and outcome measurement. Furthermore, an alternative classification algorithm distinguishing patients with OCD from controls based on subscale cutscores leads to a better sensitivity, but also to a lower specificity than discrimination based on the total scale cutscore.     

Immoral,infectious, or both? How disgust sensitivity predicts judgments of violations against COVID-19 mitigation actions

Violations against mitigation actions to prevent the spreading of the SARS-CoV-2 virus causing COVID-19, such as not wearing a mask or not practicing social distancing, were seen as immoral and could also increase the likelihood of spreading the virus. In two studies (N1 = 318, N2 = 293), we found that moral and pathogen disgust sensitivity differentially predicted perceptions of such COVID-19 violations against mitigation actions, framed as a moral, pathogen, or on a good-bad dimension, albeit in a less specific way than initially hypothesized (e.g., regarding the pathogenic framed violations, not only pathogen but also moral disgust was associated with higher perceptions of infectiousness). These results suggest that individual differences, especially in pathogen disgust (and, more inconsistently, moral disgust), are important when evaluating violations against mitigation actions. Further research on the role of moral disgust is needed.     

The Icarus Project: A Counter Narrative for Psychic Diversity

Over the past 12 years, I’ve had the good fortune of collaborating with others to create a project which challenges and complicates the dominant biopsychiatric model of mental illness. The Icarus Project, founded in 2002, not only critiqued the terms and practices central to the biopsychiatric model, it also inspired a new language and a new community for people struggling with mental health issues in the 21st century. The Icarus Project believes that humans are meaning makers, that meaning is created through developing intrapersonal and interpersonal narratives, and that these narratives are important sites of creativity, struggle, and growth. The Icarus counter narrative and the community it fostered has been invaluable for people around the world dealing with psychic diversity—particularly for people alienated by mainstream approaches. But, despite the numbers of people who have been inspired by this approach, the historical background of the Icarus Project is hard to find. It exists primarily in oral history, newspaper articles, unpublished or self-published Icarus documents, and in internet discussion forums. As the co-founder of the Icarus Project, I use this article to make my understanding of that history and its key documents more widely available.     

Cognitive processing and motor execution in the lexical decision task: a developmental study

We investigated lexical decision making in children and adults by analyzing spatiotemporal characteristics of responses involving a hand movement. Children’s and adults’ movement trajectories were assessed in three tasks: a lexical decision task (LDT), a pointing task that involved minimal cognitive processing, and a symbol task requiring a simple binary decision. Cognitive interference on motor performance was quantified by analyzing movement characteristics in the LDT and symbol task relative to the pointing task. Across age groups, movements in the LDT were less smooth, slower, and more strongly curved to the opposite response option, and these interference effects decreased steadily with age. Older children showed stronger interference effects than did adults, even though their reaction times were similar to adults’ performance. No comparable effects were found in the symbol task, indicating that task characteristics such as response mapping and decision selection alone are not able to explain the developmental differences observed in the LDT. Our results indicate substantial overlap between cognitive processing and motor execution in the LDT in children that is not captured by computational models of visual word recognition and cognitive development.     

The end is the beginning – the role of residual affective commitment in former interns’ intention to return and word-of-mouth

Interns are ubiquitous in organizations, yet relatively rarely studied, particularly after their temporary organizational membership has ended. Adopting an organizational commitment perspective, we conducted two studies to investigate two important outcomes of former interns’ membership: intention to return to their former employer, and word-of-mouth, that is, promoting the organization as an employer. In Study 1 (N = 436; lagged design), we found that residual affective commitment, that is, the remaining commitment after leaving an organization, related to former interns’ subsequent intention to return and word-of-mouth. In Study 2 (N = 236; cross-sectional design), we replicated our findings, and further found that intention to return was related to (lack of) alternative employment, hiring expectation, and attractiveness of the organization’s location. Location attractiveness also interacted with residual affective commitment on both intention to return and word-of-mouth, albeit in different directions. Overall, our findings suggest that the internship experience relates to future behaviours important for recruiting new (and old) employees. We discuss theoretical and practical implications of our studies.     

Phasic affective modulation of creativity

Thus far, it has been shown that positive compared to negative mood increases creativity, for instance, as measured by performance in the remote associate task, where participants are asked to find the common remote associate for three clue words (e.g., RABBIT CLOUD MILK solution word WHITE). The present experiments show that very brief variations in affect, lasting for only a few seconds and changing from trial to trial within participants, are sufficient to modulate creativity in that task, presumably by modulating the breadth of semantic spread. Using word valence of remote associates themselves (Experiment 1), and consonant and dissonant chords (Experiment 2) as affect inductions, it was observed that brief positive compared to negative affect increased creative performance. This evidence extends the affect-modulation hypothesis to a temporal micro-level.
