Cognitive load theory describes the mechanisms for the transfer of information from human working memory to long-term memory. This theory posits that increasing the number of interactive elements, such as interconnections, may increase cognitive load. This study investigates the impact of interconnections in concept maps on cognitive load,…

The forgetting curve is one of the most well known and established findings in memory research. Knowing the pattern of memory change over time can provide insight into underlying cognitive mechanisms. The default understanding is that forgetting follows a continuous, negatively accelerating function, such as a power function. We show that this…

Successful language comprehension requires the rapid deployment of working memory resources alongside the capacity to predict upcoming linguistic input. While previous research views these as competing factors, this dissertation explores a unified theory of processing complexity and evaluates the interaction between memory and prediction. The…

The ability of the brain to extract patterns from the environment and predict future events, known as statistical learning, has been proposed to interact in a competitive manner with prefrontal lobe-related networks and their characteristic cognitive or executive functions. However, it remains unclear whether these cognitive functions also possess…

Despite substantial improvements to memory precision in childhood, the neural mechanisms underlying these changes remain unclear. Here, 40 children (7-9 years; 22 females, 18 males; majority White) and 42 adults (24-35 years; 22 females, 20 males; majority White) modulated their approaches to memory formation--focusing on the specific details to…

Practical examinations are commonly implemented to assess student knowledge of human gross anatomy. The in-person timed cadaveric practical is a classic assessment tool; however, several new approaches, like online or oral practical assessments, have become increasingly popular in recent years due to time, space, and/or financial constraints.…

Research investigating pragmatic abilities in healthy aging suggests that both production and comprehension might be compromised; however, it is not clear how pragmatic abilities evolve in late adulthood, as well as when difficulties are more likely to arise. The aim of this study is to investigate the decline of pragmatic skills in aging, and to…

Distraction embedded in working memory tasks leads to impaired performance. This impairment is mitigated when targets and distractors that follow them share common features--a signature effect of interference by superposition. Here we propose that target-distractor similarity modulates not only forgetting from working memory but also encoding into…

Visual working memory is a capacity-limited cognitive system used to actively store and manipulate visual information. Visual working memory capacity is not fixed, but varies by stimulus type: Stimuli that are more meaningful are better remembered. In the current work, we investigate what conditions lead to the strongest benefits for meaningful…

We observed differences in cognitive functions between middle-aged female and male Wistar rats. Both (like youngsters) discriminated new versus familiar objects, showing similar short- and long-term memory (STM and LTM, respectively). Only females show robust LTM for new location of an object. Both successfully form LTM of inhibitory avoidance,…

Since the Middle Ages, Augustine and the wealth of his writings have had an enormous impact on Western philosophical thinking. His approach to time and memory, which he sets out in his eleventh book of the "Confessions," is one of the most important sources for research about the philosophy of time. Augustine describes time as a…

The animacy effect refers to the memory advantage of words denoting animate beings over words denoting inanimate objects. Remembering animate beings may serve important evolutionary functions, but the cognitive mechanism underlying the animacy effect has remained elusive. According to the richness-of-encoding account, animate words stimulate…

Contextual shifts are crucial for episodic memory, setting event boundaries during event segmentation. While lab research provides insights, it often lacks the complexity of real-world experiences. We addressed this gap by examining perceptual and conceptual boundaries using virtual reality (VR). Participants acted as salespeople, interacting with…

Spatial navigation relies on extracting environmental information to determine where to go. To support navigation behavior, navigational aids, such as maps, compasses, or global positioning systems (GPSs), offer access to easily extractible information, but do these aids enhance spatial memory? Here, we propose the hypothesis that navigation aids…

In today's digital world, understanding refresh-rate implications on visual perception and energy consumption is crucial. While high refresh rates enhance motion perception and user experience, they also increase energy usage, prompting the need for adaptive solutions like variable refresh rates. This study examines whether users notice or are…
