Consensus definitions of perception-action-integration in action control.

The literature on action control is rife with differences in terminology. This consensus statement contributes shared definitions for perception-action integration concepts as informed by the framework of event coding.

Comparison of mucus and serum biomarker sampling in chronic rhinosinusitis with nasal polyps.

Objective: The objective of this study was to analyze advantages and disadvantages of mucus and serum for biomarker analysis.

Methods: This study includes prospective study of 61 CRS with nasal polyps patients who were followed over 24 months and over nine time points after functional endoscopic sinus surgery. At each time points, the nasal polyp score (NPS) was assessed and mucus as well as serum was collected.

Evidence of task-triggered retrieval of the previous response: a binding perspective on response-repetition benefits in task switching.

In task switching, response repetitions (RRs) usually yield performance benefits as compared to response switches, but only when the task also repeats. When the task switches, RR benefits vanish or even turn into costs, yielding an interaction between repeating versus switching the task and the response (the RR effect). Different theoretical accounts for this RR effect exist, but, in the present study, we specifically tested a prediction derived from binding and retrieval accounts.

The influence of event segmentation by context on stimulus-response binding.

A core characteristic of auditory stimuli is that they develop over time. Referring to the event segmentation theory, we assume that the on- and offset of a contextual sound indicates the start and end of an event. As a consequence, stimuli and responses appearing within a common auditory context may be integrated more likely/strongly, forming so-called event files, than those appearing in different auditory contexts.

Effect of postoperative systemic prednisolone on short-term and long-term outcomes in chronic rhinosinusitis with nasal polyps: A multi-centered randomized clinical trial.

Introduction: The objective of this study was to determine whether postoperative additive systemic steroid administration in chronic rhinosinusitis with nasal polyps (CRSwNP) impacted selected endoscopic, subjective and objective outcome measures.

Methods: This was a prospective, randomized, double-blind, placebo-controlled, noninferiority multicenter trial of n=106 patients with CRSwNP. All patients underwent primary functional endoscopic sinus surgery (FESS) followed by topical nasal steroids.

Core Mechanisms in Action Control: Binding and Retrieval.

This special collection focuses on action control and its two postulated core processes, namely feature binding and retrieval. Action control is an important topic as humans interact with their environment by means of goal-directed behavior, i.e.

Binding of task-irrelevant contextual features in task switching.

Research in attention and action control produced substantial evidence suggesting the presence of feature binding. This study explores the binding of task-irrelevant context features in cued task switching. We predicted that repeating a context feature in trial n retrieves the trial  - 1 episode.

Inter-Trial Variability of Context Influences the Binding Structure in a Stimulus-Response Episode.

There is strong evidence that stimuli and responses are bound together in a direct () fashion into an episodic representation called (or ). However, in an auditory negative priming study in which participants were required to respond to the target stimulus and to ignore the distractor stimulus, context information (i.e.

Contextual Features of the Cue Enter Episodic Bindings in Task Switching.

Evidence suggests that the features of a stimulus and the actions performed on it are bound together into a coherent mental representation of the episode, which is retrieved from memory upon reencountering at least one of these features. Effects of such binding and retrieval processes emerge in action control, such as in multitasking situations like task switching. In the task-switching paradigm, response-repetition benefits are observed in task repetitions, but response-repetition costs in task switches.

Saliency determines the integration of contextual information into stimulus-response episodes.

When humans perform a task, it has been shown that elements of this task, like stimulus (e.g., target and distractor) and response, are bound together into a common episodic representation called stimulus-response episode (or event file).

LED-based light sources optimised for high colour rendition from an end users' perspective.

Light emitting diode (LED) technology is continuously developing, leading to the current transition from simple phosphor-converted LED lamps to LED lamps optimised for high colour rendition in residential lighting. To assess whether such optimised phosphor-converted LED lamps may fulfil the end users' needs better than simple phosphor-converted LED lamps we asked participants to rank two particular brands of phosphor-converted LED lamps optimised for high colour rendition, a typical simple phosphor-converted LED lamp and a halogen lamp for pleasantness, naturalness and purchase preference. The results of two experiments suggest that phosphor-converted LED lamps optimised for high colour rendition have the potential to outperform simple phosphor-converted LED lamps and even to measure up to traditional halogen lighting in terms of user preference.

Binding and Retrieval in Action Control (BRAC).

Human action control relies on representations that integrate perception and action, but the relevant research is scattered over various experimental paradigms and the theorizing is overly paradigm-specific. To overcome this obstacle we propose BRAC (binding and retrieval in action control), an overarching, integrative framework that accounts for a wide range of seemingly unrelated findings by assuming 'two core processes: feature binding and retrieval'. In contrast to previous approaches, we define binding and retrieval as functionally different and separable processes that independently contribute to the observed effects.

A common type of commercially available LED light source allows for colour discrimination performance at a level comparable to halogen lighting.

As light sources based on light emitting diodes (LED) are increasingly used to replace classic tungsten-based light sources in household lighting applications, possible impairments of colour perception under those light sources due to a different spectral power distribution become a major concern. The Colour Rendering Index (CRI) which is the only measure available to the end user is controversial and does not represent a comprehensive measure of colour perception. Aspects of colour perception disregarded by the CRI such as colour discrimination have to be taken into account as well.

Links Between Users' Online Social Network Homogeneity, Ambiguity Tolerance, and Estimated Public Support for Own Opinions.

False consensus effect (FCE) refers to a cognitive bias of relative overestimation of public support for one's own opinion. FCE has been linked to selective social interaction with like-minded people as well as to selective exposure to attitude-consistent information. Previous studies tested these links mostly in offline settings.

Inhibition of irrelevant response codes is affected by matching target-distractor modalities.

Lateralized responses to central targets are facilitated when distractors are presented ipsilaterally (congruent trials) compared with contralaterally (incongruent trials) to the response. This accessory Simon effect is explained by assuming that distractors generate a spatial code that conforms to, or conflicts with, the response. The effect typically diminishes as the distractor-target interval increases.

Correction to: Contextual modulation of prime response retrieval processes: Evidence from auditory negative priming.

The Publisher regrets that two erroneous values were introduced by the typesetter when performing proof corrections.

Contextual modulation of prime response retrieval processes: Evidence from auditory negative priming.

Contextual similarity between learning and test phase has been shown to be beneficial for memory retrieval. Negative priming is known to be caused by multiple processes; one of which is episodic retrieval. Therefore, the contextual similarity of prime and probe presentations should influence the size of the negative priming effect.

Reading from computer screen versus reading from paper: does it still make a difference?

Four experiments were conducted to test whether recent developments in display technology would suffice to eliminate the well-known disadvantages in reading from screen as compared with paper. Proofreading speed and performance were equal for a TFT-LCD and a paper display, but there were more symptoms of eyestrain in the screen condition accompanied by a strong preference for paper (Experiment 1). These results were replicated using a longer reading duration (Experiment 2).

Event-related potentials in response to cheating and cooperation in a social dilemma game.

A sequential prisoner's dilemma game was combined with psychophysiological measures to examine the cognitive underpinnings of reciprocal exchange. Participants played four rounds of the game with partners who either cooperated or cheated. In a control condition, the partners' faces were shown, but no interaction took place.

The time-course of distractor processing in auditory spatial negative priming.

The spatial negative priming effect denotes slowed-down and sometimes more error-prone responding to a location that previously contained a distractor as compared with a previously unoccupied location. In vision, this effect has been attributed to the inhibition of irrelevant locations, and recently, of their task-assigned responses. Interestingly, auditory versions of the task did not yield evidence for inhibitory processing of task-irrelevant events which might suggest modality-specific distractor processing in vision and audition.

Effects of spatial response coding on distractor processing: evidence from auditory spatial negative priming tasks with keypress, joystick, and head movement responses.

Prior studies of spatial negative priming indicate that distractor-assigned keypress responses are inhibited as part of visual, but not auditory, processing. However, recent evidence suggests that static keypress responses are not directly activated by spatially presented sounds and, therefore, might not call for an inhibitory process. In order to investigate the role of response inhibition in auditory processing, we used spatially directed responses that have been shown to result in direct response activation to irrelevant sounds.

Positive display polarity is particularly advantageous for small character sizes: implications for display design.

Objective: To test the display luminance hypothesis of the positive polarity advantage and gain insights for display design, the joint effects of display polarity and character size were assessed with a proofreading task

Background: Studies have shown that dark characters on light background (positive polarity) lead to better legibility than do light characters on dark background (negative polarity), presumably due to the typically higher display luminance of positive polarity presentations.

Method: Participants performed a proofreading task with black text on white background or white text on black background. Texts were presented in four character sizes (8, 10, 12, and 14 pt; corresponding to 0.

Smaller pupil size and better proofreading performance with positive than with negative polarity displays.

The 'positive polarity advantage' describes the fact that reading performance is better for dark text on light background (positive polarity) than for light text on dark background (negative polarity). We investigated the underlying mechanism by assessing pupil size and proofreading performance when reading positive and negative polarity texts. In particular, we tested the display luminance hypothesis which postulates that the typically greater brightness of positive compared to negative polarity displays leads to smaller pupil sizes and, hence, a sharper retinal image and better perception of detail.

Intact episodic retrieval in older adults: evidence from an auditory negative priming task.

Unlabelled: BACKGROUND/STUDY CONTEXT: The negative priming effect has been traditionally interpreted as the inhibitory aftereffect of distractor processing. According to inhibitory deficit theory, older adults should be more impaired by auditory distractors. Recent studies have shown that episodic retrieval processes are involved in the effect.

Auditory spatial negative priming: what is remembered of irrelevant sounds and their locations?

The categorization and identification of previously ignored visual or auditory stimuli is typically slowed down--a phenomenon that has been called the negative priming effect and can be explained by the episodic retrieval of response-inadequate prime information and/or an inhibitory model. A similar after-effect has been found in visuospatial tasks: participants are slowed down in localizing a visual stimulus that appears at a previously ignored location. In the auditory modality, however, such an after-effect of ignoring a sound at a specific location has never been reported.
