Recent evidence suggests that consciousness of encoding is not necessary for the rapid formation of new semantic associations. We investigated whether unconsciously formed associations are as semantically precise as would be expected for associations formed with consciousness of encoding during episodic memory formation. Pairs of faces and written occupations were presented subliminally for unconscious associative encoding. Five minutes later, the same faces were presented suprathreshold for the cued unconscious retrieval of face-occupation associations. Retrieval instructions required participants to classify the presented individuals according to their putative (1) regularity of income, (2) length of education, and (3) creativity value of occupational activity. The three instructions yielded more classifications consistent with a person's occupation if the person had been subliminally presented with his written occupation versus a meaningless word (control condition). This suggests that consciousness is not necessary to encode, long-term store, and retrieve semantically precise associations between primarily unrelated items.

Statistical learning optimizes limited working memory by abstracting probabilistic associations among specific items. However, the cognitive mechanisms responsible for the working memory representation of abstract and item-specific information remain unclear. This study developed a learning-memory representation paradigm and tested three participant groups across three conditions: control (Experiment 1), item-specific encoding (Experiment 2), and abstract encoding (Experiment 3).

Background: Operating room (OR) shadowing allows nursing students to observe high-stakes teamwork and clinical decision-making. However, the emotional and professional impact of such experiences on novice nurses remains underexplored.
Methods: This qualitative study explored how a single episode of OR shadowing during undergraduate clinical training influenced novice nurses' emotional responses and professional development.

Non-invasive methods for observing the morphology of living oleaginous yeast are ideal for optimizing the production of various oils, such as food oils, oleochemicals, and biodiesel, from oleaginous yeast. However, existing methods have been developed to target budding yeast without high oil production ability and extract regions of entire cells. This study is the first to target oleaginous yeast, namely, Lipomyces starkeyi, demonstrating a method for extracting regions of L.

Generative activity can interfere with later retrieval of related concepts and words. This semantic interference has been ascribed to long-term adaptive learning mechanisms that promote access to selected representations and hinder access to coactivated competitors. Some accounts in the memory literature posit that the punishment doled out to coactivated competitors may actually serve as a catalyst for more robust relearning in comparison to never-punished controls.

Lymph node (LN) metastasis is a key prognostic factor in laryngeal squamous cell carcinoma (LSCC). Emerging evidence implicates the role of the microbiome in cancer progression. This study aimed to investigate the microbial features associated with lymph node metastasis in LSCC and their potential for patient stratification.
