This paper aims to present the results of a series of several Brazilian institutions that have been carrying out lung cancer screening (LCS).

This is a retrospective, cohort study, with follow-up of individuals of both sexes, with a heavy smoking history, who participated in LCS programs between December 2013 and January 2021 in six Brazilian institutions located in the states of São Paulo, Rio Grande do Sul, and Bahia.

Three thousand four hundred seventy individuals were included, of which 59.8% were male (n = 2,074) and 50.6% were current smokers (n = 1,758), with 60.7 years (standard deviation 8.8 years). Lung-RADS 4 was observed in 233 (6.7%) patients. Biopsy was indicated by minimally invasive methods in 122 patients (3.5%). Two patients who demonstrated false-negative biopsies and lung cancer were diagnosed in follow-up. Diagnosis of lung cancer was observed in 74 patients (prevalence rate of 2.1%), with 52 (70.3%) in stage I or II. Granulomatous disease was found in 20 patients. There were no state the creation of organized screening programs in regions still endemic for tuberculosis and other granulomatous diseases.Dual-tasks (DT) require the employment of task-order representations that schedule the processing of 2 tasks. Evidence for this assumption stems from the observation that in DTs with variable order, performance is improved in trials with repeated processing order relative to the preceding trial in comparison to trials with reversed processing order. So far, it is an open question whether these order representations only contain order information or whether they also integrate component task information. To tackle this question, we applied a DT with variable task-order consisting of an auditory and a visual task. In Experiment 1, in addition to task-order, the visual task varied randomly from trial to trial while the auditory task kept constant. In Experiment 2, the auditory task varied. In Experiment 3, both component tasks varied. In all experiments, performance benefits occurred in trials with a repeated relative to trials with a reversed processing order, irrespective of a repeated or a changed component task. This indicates that order representations in DTs only contain order information. The findings are in line with the view that multitasking situations are represented as an agglomeration of distinct components that can be individually adjusted to changing task demands.

However, background scenes coinciding with RSVP targets are better remembered than those coinciding with RSVP distractors, a paradoxical finding known as the attentional boost effect. But does the effect originate from the detection of the RSVP target or from the need to respond to it? To dissociate target detection from response, we investigated the attentional boost effect using a visual search task. Participants searched for a target among distractors while memorizing concurrently presented background objects. The search target could be present or absent. In different experiments, participants pressed a button on target-present trials only, target-absent trials only, or made a two-choice present/absent response. Results showed that objects paired with a Go response were better remembered than objects paired with a No-Go response, regardless of whether responses were associated with target-present or target-absent trials. This finding was replicated in experiments that required covert counting rather than an immediate button press response. These findings are the first to extend the attentional boost effect to visual search and demonstrate that the need to respond, not the detection of a search target, drives the effect for concurrently presented stimuli.

Drivers must monitor errors and initiate steering corrections of appropriate magnitude and timing to maintain a safe lane position. The perceptual mechanisms determining how a driver processes visual information and initiates steering corrections remain unclear. Previous research suggests 2 potential alternative mechanisms for responding to errors (a) perceptual evidence (error) satisficing fixed constant thresholds (Threshold), or (b) the integration of perceptual evidence over time (Accumulator). To distinguish between these mechanisms, an experiment was conducted using a computer-generated steering correction paradigm. Drivers (N = 20) steered toward an intermittently appearing "road-line" that varied in position and orientation with respect to the driver's position and trajectory. One key prediction from a Threshold framework is a fixed absolute error response across conditions regardless of the rate of error development, whereas the Accumulator framework predicts that drivers would respond to larger absolute errors when the error signal develops at a faster rate. Results were consistent with an Accumulator framework; thus we propose that models of steering should integrate perceived control error over time in order to accurately capture human perceptual performance.

There are several theories of how local-to-global pooling occurs, but they all predict that global motion perception is a continuous process, such that increasing the strength of motion energy should gradually increase the precision of perceived motion directions. We test this prediction against the alternative that global motion perception is discrete Motion is either perceived with high precision or fails to be perceived altogether. Data from human observers provides clear evidence that, whereas pooling local motion energy is continuous, the segmentation of local signals into coherent global motion patterns is a discrete process. This result adds motion perception to the growing list of processes that exhibit evidence of all-or-none visual awareness.

Evidence for and against this theory has been provided from two experimental paradigms. Here, event-related potentials (ERPs) recorded in a novel Go/No-Go paradigm disconfirmed all three of tenets of the theory. Participants were instructed to search cyan-item displays for a salient orientation singleton (Go trials) and to ignore randomly intermixed yellow-item displays that could also contain an orientation singleton (No-Go trials). ERP components associated with attentional orienting (posterior contralateral N2; N2pc), distractor suppression (distractor positivity; PD), and stimulus relevance (P2a) were isolated to test predictions stemming from the salience-driven selection theory. On No-Go trials, the salient oddball elicited a PD rather than an N2pc, indicating that it was suppressed, not attended. Moreover, a P2a emerged before the N2pc on Go trials, demonstrating that observers first evaluated the global color of each display and then decided to search for the oddball (Go trials) or to ignore it (No-Go trials). We conclude that goal-driven processes can lead to the prevention of salience-driven attention capture by salient visual objects within the attentional window.

Here, we used gaze-contingent eye tracking to examine how such resources are dynamically reallocated from old to new information entering working memory. As participants looked sequentially at items, we interrupted the process at different times by extinguishing the display as a saccade was initiated. After a brief interval, participants were probed on one of the items that had been presented. Paradoxically, across all experiments, the final (unfixated) saccade target was recalled more precisely when more items had previously been fixated, that is, with longer rather than shorter saccade sequences. This result is difficult to explain on current models of working memory because recall error, even for the final item, is typically higher as memory load increases. The findings could however be accounted for by a model that describes how resources are dynamically reallocated on a moment-by-moment basis. During each saccade, the target is encoded by consuming a proportion of currently available resources from a limited working memory, as well as by reallocating resources away from previously encoded items. These findings reveal how working memory resources are shifted across memoranda in active vision.

Human participants responded to tactile stimuli delivered to the same hand at 6 possible locations during an insect's approach. Tactile reaction times were faster when looming stimuli were closer to the hand, especially for spiders, and faster when insects loomed on a collision path than on a near-miss path. IRAK4-IN-4 This latter finding suggests that human reactions to looming stimuli are not merely automatic reflexes but that contextual knowledge about the trajectory of looming objects is included in predicting their impact.

During the present pandemic, emerging literature argues that front-line officers' mental health is at greater risk while performing their duties. However, little is known of the impact on the work of professionals in analytical/intelligence roles in police, law enforcement, and justice organizations. Therefore, this study explored the impact of the current pandemic on the experiences of analysts working in these roles.

Sixteen semi-structured interviews were conducted with these analysts and template analysis was used to analyze the transcriptions.

Nine themes were identified namely "A new safe workplace," "Opportunity to catch up," "Communication delays," "Discomfort with commuting," "Facilitating offending," "Isolation," "Loss of social support," "Insufficient technical resources," and "Work-life imbalance."

Analysts when home-working with traumatic material were facing challenges, such as limited human interaction and no immediate support from employers, which were causing psychological distress during these unprecedented times.
