AI Article Synopsis
- Watson and Humphreys (1997) demonstrated that observers can ignore distracting items while searching for a target, a phenomenon known as 'visual marking' that enhances performance by reducing relevant items.
- Recent studies have explored visual marking in continuously moving items and found that shared features and spatial relationships play a crucial role in its effectiveness.
- The current study tested visual marking with items that move in a single discrete jump, but found that marking did not occur, suggesting that the movement style may impact the effectiveness of visual marking.
Article Abstract
Watson and Humphreys (1997 Psychological Review 104 90-122) showed that when searching for a target, observers can ignore a previewed set of distractors (other items), effectively decreasing the number of relevant items in a difficult search display and thus speeding performance ('visual marking'). Other researchers have more recently investigated visual marking for continuously moving items, finding that shared features, and preserved inter-item spatial relationships, are helpful. Here, we tested whether visual marking occurs for a set of initial items that moves in one discrete jump (preserving shared features and inter-item spatial relationships). Marking did not occur in these displays, and we interpret this result in the context of previous research on visual marking.

Aberrant controllability of functional connectome during working memory tasks in patients with schizophrenia and unaffected siblings.

Background: Working memory deficit, a key feature of schizophrenia, is a heritable trait shared with unaffected siblings. It can be attributed to dysregulation in transitions from one brain state to another.
Aims: Using network control theory, we evaluate if defective brain state transitions underlie working memory deficits in schizophrenia.
This study aimed to delineate trends in intervertebral disc degeneration among Mexican patients, specifically focusing on the distribution and correlation between BMI and Pfirrmann classification results within the Mexican population. Conducted using the public health database of Mexico City. The study involved 51 patients sampled via convenience sampling, with exclusive utilization of internal MRI data from L4-L5 and L5-S1 discs.

Growing research on the non-visual impacts of light underscores the importance of architectural glazing systems in managing transmitted shortwave solar light and shaping indoor circadian light, vital for enhancing well-being. This study, conducted in two phases, evaluates the effectiveness of existing window properties in predicting their contribution to circadian lighting. Initially, a decision tree analysis assessed these properties and revealed that although traditional glazing metrics are not entirely accurate for circadian performance estimations, they can still be effective when supplemented with specific thresholds as rapid tools for selecting windows optimized for circadian health.

Latent fingerprints (LFPs) are invisible impressions that need to be developed before being used for criminal investigation; however, existing fingerprint visualization techniques face challenges, such as complex preparation and poor contrast. To advance practical fingerprint detection, green-emissive micron-sized curcumin/kaolin composites were synthesized a facile and cost-effective one-step physical cross-linking method, which exhibited unprecedented performance in developing diversified marks, including LFPs, knuckle prints, palm prints, and footprints, with clear three-level details on various substrates. Notably, the powders successfully developed LFPs that were aged for 30 days and even up to 100 days, meeting the stringent requirements for comprehensive forensic application.
