Figure from the paper: Time-frequency plots per condition, with the baseline corrected oscillatory power measures. The upper four subplots are from a cluster of mid-frontal channels (Fz, F1, F2, FC1, FC2) and the lower five subplots are from a posterior channel cluster (PO3, POz, PO4, O1, Oz, O2). The events (onsets of memory array, interruption, retro-cue, and probe) are marked by vertical dotted lines, and their timing changes depending on condition. Mind that flexible condition subplots have a white shaded area around 4000 ms, which represent the 95% confidence interval range of resumption times on flexible trials (95%CI 3699.4 - 4682.95).
Interruptions are common in working life, negatively affecting task performance and long-term psychological well-being. Research supported by software written with #Lazarus_IDE / #Free_Pascal demonstrates the important role of resumption time and individual flexibility.

Graphical Abstract. As a replacement subsequently follows the abstract: (1) Background: Individuals with high levels of state depression are hypothesized to have an impairment of attentional control functions necessary for filtering irrelevant information. This study used the event-related potential of early PD, a marker of distractor suppression, and N2pc, an indicator of attentional capture to investigate whether high state depression affects selective attention in ignoring or suppressing distractors. (2) Methods: Thirty-three undergraduate students completed the Depression Anxiety Stress Scale-21 (DASS-21) and performed a modified, delayed match-to-sample task. Participants encoded abstract shapes under low or high perceptual load conditions in the visual working memory while ignoring a lateralized Chinese character as a task-irrelevant singleton distractor. (3) Results: Individuals with high state depression failed to suppress the distractor, as evidenced by the absence of early PD. Under low perceptual loads, they also displayed a significant N2pc component, indicating attentional allocation to the distractor. In contrast, low-state-depression participants successfully suppressed the distractor, showing early PD and the absence of N2pc. (4) Conclusions: These findings suggest that high-state-depression individuals have an impairment in top–down attentional control, particularly in feature-based selective attention. This deficit hinders the ability to filter out irrelevant information, potentially contributing to cognitive difficulties associated with depression.
Participants received visual instructions for the delayed match-to-sample task while listening to a pre-recorded audio file in MP3 format containing the instructions delivered by an AI voice.
Persons with #depression may have difficulties in filtering out irrelevant information. This hypothesis could be proved with a computerised experiment based on software written with the #Lazarus_IDE for #Free_Pascal.

Water may contain dissolved substances that impact its quality and may be harmful. To better understand the processes of purification, an international team developed a mathematical model of impurity diffusion and #simulation software using the #Lazarus_IDE and #Free_Pascal.

Figure from the paper showing the experimental paradigm. Shortly, participants were asked to memorize the orientation of coloured bars before being presented with an arithmetic task.
Figure from the paper: Time–frequency plots per interruption condition averaged across midfrontal EEG channels.
Plot from the paper: Significant clusters showing the main effects of interruption averaged across duration conditions with the topographies marking the distribution of two significant clusters over the scalp. The vertical dashed lines indicate the onsets of the retro-cue (0 ms) and the memory probe (1,000 ms).
In working life, interruptions are widespread and can impair task performance. In an #EEG experiment that was controlled by software written in #Lazarus and #Free_Pascal, researchers found that temporal flexibility can benefit subgroups of workers.

Simulation speed with implementations in different programming languages. Shown is the time needed to simulate a first-order linear feedback loop (A) and a zeroth-order MiMe-NoCoDI loop (B) dependent on the number of iterations (proportional to simulated time, abscissa) based on implementations of the simulation program and the CyberUnits Bricks library in S, Python, Swift, C++ and Object Pascal. The ordinate is logarithmically scaled and represents the mean of 10 replications of each number of iteration steps.
Which programming language is fit for high-performance computer simulations in biomedical #cybernetics? We found that #Free_Pascal generates faster code than S/R and #Python. Interestingly, Object #Pascal even outperforms #Swift and C++. 🧪🩺
