Full-text available
Within the last years, generative artificial intelligence (AI) has not only entered the field of creativity; it might even be marking a turning point for some creative domains. This raises the question of whether AI also poses a turning point for scientific creativity, which comprises the ability to develop new ideas or methodological approaches in...
Conference Paper
The increasing spread of artificial intelligence (AI) applications underscores the necessity for an interdisciplinary initiative to ensure the trustworthiness of AI and its alignment to human values and security. A distinction is made between trustworthy AI and trust in AI. The former is defined by adherence to ethical, technical, and legal standar...

We present a novel method for analyzing response trajectory tracking data. Limiting behavioral experiments to discrete, key-press response measures, such as reaction times and accuracy, is unsatisfactory for observing the ongoing dynamics of cognition. We assessed the utility of continuous response tracking in Virtual Reality (VR) by comparing it t...

Short-term memory for sequences of verbal items such as written words is reliably impaired by task-irrelevant background sounds, a phenomenon known as the “Irrelevant Sound Effect” (ISE). Different theoretical accounts have been proposed to explain the mechanisms underlying the ISE. Some of these assume specific interference between obligatory soun...

Creative problem-solving has been described as an iterative process of divergent and convergent modes of thinking. With this opinion paper, we illustrate how some tasks, commonly used for the neuroscientific investigation of creativity might provide a condensed representation of divergent and convergent thinking, respectively. We have identified th...

Presentation
Divergent thinking (i.e., the generation of multiple ideas by thinking in many different directions; Runco, 2007) has widely been recognized as the underlying process of creativity. On the other hand, convergent thinking still is oftentimes exclusively associated with knowledge, fluid intelligence and logical thinking. However, creativity is charac...
Article
Full-text available
This study investigates neural mechanisms of divergent and convergent thinking in the verbal knowledge domain while taking into account activation related to working memory (WM). Divergent thinking was assessed using the Alternate Uses Task (AUT) and convergent thinking using the Compound Remote Associates task (RAT). We analyzed upper alpha band (...

The human brain extracts statistical regularities from the surrounding environment in a process called statistical learning. Behavioural evidence suggests that developmental dyslexia affects statistical learning. However, surprisingly few studies have assessed how developmental dyslexia affects the neural processing underlying this type of learning...

Introduction Long-term memory retention is enhanced after testing compared to restudying (testing effect). Notably, memory retrieval further improves when correct-answer feedback is provided after the retrieval attempt (test-potentiated encoding–TPE). Methods To evaluate whether explicit positive or negative feedback further enhances memory perfor...

The testing effect describes the finding that retrieval practice enhances memory performance compared to restudy practice. Prior evidence demonstrates that this effect can be boosted by providing feedback after retrieval attempts (i.e. test-potentiated encoding [TPE]). The present fMRI study investigated the neural processes during successful memor...

Background Neurotypical individuals categorize items even during ultra-rapid presentations (20 ms; see Thorpe et al. Nature 381: 520, 1996). In cognitively able autistic adults, these semantic categorization processes may be impaired and/or may require additional time, specifically for the categorization of atypical compared to typical items. Here,...

Most studies investigating the effects of environmental noise on children’s cognitive performance examine the impact of monaural noise (i.e., same signal to both ears), oversimplifying multiple aspects of binaural hearing (i.e., adequately reproducing interaural differences and spatial information). In the current study, the effects of a realistic...

Chronic aircraft noise impairs children's cognition. In the literature, LAeq and Lden are the dominating noise exposure metrics for calculating the relationship between noise and cognition, although other noise metrics such as the number above threshold (NAT) exist. There is initial evidence from regression models that the NAT metric served as a se...

Instruction at school relies heavily on oral discourse. Listening comprehension is thus of major importance for successful learning. However, in many classrooms, children’s listening is impaired by unfavourable acoustic conditions such as indoor noise and reverberation. Most studies on the effects of environmental noise on children’s speech percept...

Immediate serial recall of visually presented items is reliably impaired by task-irrelevant speech that the participants are instructed to ignore (“irrelevant speech effect,” ISE). The ISE is stronger with changing speech tokens (words or syllables) when compared to repetitions of single tokens (“changing-state effect,” CSE). These phenomena have b...

Introduction: In adults, olfactory loss is one of the earliest and most frequent acute clinical manifestations of SARS-CoV-2 infection. The number of children infected with SARS-CoV-2 is relatively small, perhaps due to the lower expression of Angiotensin Converting Enzyme 2 (ACE2) in children compared to adults. Little is known about foetal impair...

A considerable amount of the population in more economically developed countries are functionally illiterate (i.e., low literate). Despite some years of schooling and basic reading skills, these individuals cannot properly read and write and, as a consequence have problems to understand even short texts.

Encoding of perceptual categorical information has been observed in later cognitive processing like memory encoding and maintenance, starting around 300 ms after stimulus onset (P300). However, it remains open whether categorical information is also encoded in early perceptual processing steps (reflected in the mismatch negativity component; vMMN)....

Perceptual categorization is an important cognitive function. In the auditory domain, categorization already occurs within the first 200 ms of information processing, as indexed by the mismatch negativity. Here, we assessed the characteristics of the visual mismatch negativity (vMMN) elicited during the categorization of previously unknown visual s...

When immersive virtual reality users employ digital self-representations, i.e., avatars, they may be subject to the Proteus effect. This effect describes changes in attitudes and behaviors in accordance with identity cues derived from the employed avatar’s appearance, which can persist after leaving virtual reality. Individual reactions to the expe...
