For the sake of control, one of my reviewers asked me how I can control for color blindness. I found the Ishihara cards, which can reliably help me with red and green, but I can't find a test for blue and yellow. I'd appreciate your ideas on tests for controlling this.

I found three major approaches of the neurological mechanism of attention:
a)mirror neurons related with association areas and the develop of a specific task,
b) lateral intraparietal cortex on forced decision task
c) dorsal prefrontal cortex in taks related with working memory
Is there another important approach? Are these systems related? Is there a better paradigm to understand attention process on a neuroscientific poinf of view?
Hi Roberto, are you looking at the moments of increased peaks in the EDA, or use tonic changes?
I am afraid that by using EDA you may not have a clear and direct relationship between attention and BOLD. But I think what you are trying to do is to have an implicit measure of attention by using EDA as dependent measure, is that right? Then, you need to look at the literature about how EDA and BOLD are related first (even without considering attention related changes on EDA), then examine whether those brain areas should be active at the time of increased external attention in your paradigm.
One very important thing that you need to consider is that physiological responses have corresponding effects on BOLD, and many people think that these are noise.Following

Specially the effects of our expectations with regards to basic affective and neutral incoming stimuli. And I need to get a feel for the basic tasks and paradigms that are used to measure emotional expectancy, but I can't seem to find anything in that scenario. If anyone knows of a review of any kind, or anything along the lines of expectancy biases that resembles this, I would greatly appreciate it.

- Gerit Pfuhl added an answer:Looking for metrics for attention: What is the best way to obtain a quantified representation of human attention?
We are developing Attention-Aware Systems, which includes the Sensing (Estimation), Modeling and Management of user attention.
In my research activitise I was not able to find a generally valid metric, categorization or quantification of attention.
There are different approaches: in cognitive sciences, attention us usually analyzed as the performance in the fulfillment of given tasks => a percentage scale of an average performance. in HCI publications, researchers often use their own categories or scales that are chosen arbitrarily.
In my work I was using scales, as well as attention types as categories...
So my question is whether you know some way of parametrization for human attention, or have any creative approach to follow?
given that attention is not equal awareness those scales are of no use for your tasks. Vigilance or measures of sleepiness may though provide you with a scale. More objectively might be to use the EEG, as alertness/attention towards a stimulus is signaled in the power spectrum i.e. beta waves - non-invasive and two electrodes on the scalp suffice (see: Jung et al. 1997 Estimating alertness from the EEG power spectrum)Following

The necessity of corporate social responsibility was widely discussed while talking about private sector. Not long ago the attention was devoted also to social responsibility in the public sector. What is Your understanding about social responsibility features in the public sector?
In my view, social responsibility in the public sector cannot be completely different from what it is in the private sector. However, there is minor differences in who the stakeholders are in the public sector from who they are in the private sector; in view of that, the focus of social responsibility in the public sector would be to ensure quality service delivery to the public, maintain good relationship with employees and ensuring environmental safety.Following

Attentional selection is biased toward mood-congruent stimuli. Becker, Mark W.; Leinenger, Mallorie. Emotion11.5 (Oct 2011): 1248-1254.........A positive, negative, or neutral mood manipulation was followed by an attentionally demanding multiple-object tracking task. During the tracking task, participants were more likely to notice an unexpected face when its emotional expression was congruent with participants' mood. This was particularly true for the frowning face, which was detected almost exclusively by participants in the sad mood induction condition. This attentional bias toward mood-congruent stimuli provides evidence that one's temporary mood can influence the attentional filter, thereby affecting the information that one extracts from, and how one experiences the world.

- Ravinder Jerath added an answer:Can anyone explain why HRV is reduced during attention?Greater resting heart rate variability (HRV) is associated with better executive functioning, better working memory performance and more context-appropriate motivational responses.
Furthermore HRV is reduced during attention and physical activity. However, I have not found a satisfactory explanation why this is so?
It is well known that all emotions have their own pattern of respiration. Depth of respiration and its frequency are directly related to the dominance of LF or HF HRV. Closing the eyes and breathing slowly during breathing deeply during the practice of "Pranayama " a form of meditation can modulate the sympathetic to parasympathetic response .(Jerath 2006 medical hypothesis) . So does deep SW sleep when the repiration is slow and deep and there is increase HRV . ( Jerath , Branes 2014 sleep medicine) The slowly adapting strech receptors in the lungs during attention would send depolarizing modulatory signals to respiratory , limbic and cortical centers. These signals can depolarize the cells based on degree of cardiorespiratory synchronization. In meditaion and SW sleep the high degree of synchronization of respiration and heart (1:4) or more induces heperpolarization and inhibition of all cells over 20 minutes leading to homeostatic change in membrane potential of excitable and non neural cells. In attention the transient change in cardiorespiratory synchronization could induce change in HRV simultaneously associated with change from alpha to beta waves on EEG. Attention is also associtaed with deactivation of default mode network in the brain.Following

The initial subject for this question was an EEG of someone who was in a lucid dream state. The proband was counting numbers in this state. And what was showing up was an MMN just the moment the proband started to count. However this MMN did not show up in an awake state.
All in all: I am kind of interested in the question if it is possible to find some kind of "physical laws" for dream environments which make it possible to observe a dream environment just like an exobiologist tries to find laws for life on other planets in order to come to some conclussions what this environment might be like.

- Jack Wilson added an answer:How to measure accurately ERP/ERFs when participants need to do an early saccade?Basically, in EEG and MEG research, we reject some trials for our average if our participants blinked or made some saccades, this due to 1) the distortion caused on the MEG/EEG signal and because 2) the visual input will shift across the retina, which creates a saccade-induced ERP response (Luck, 2005). Thus, our participants have to fixate the center of the screen.
It is well known that it's possible to correct the signal using independent component analysis (ICA) or other artifact corrections algorithms. However, which could be the best manner to investigate the early saccadic behavior toward complex picture without altering the sensory ERPs?Horizontal/vertical eye occulograms (H/VEOG) is the only thing I can think of.Following
- Mohammad Firoz Khan added an answer:What is Consciousness?In his recent book *Consciousness and the Brain*, Stanislas Dehaene writes "What counts as genuine consciousness, I will argue, is conscious access -- the simple fact that usually, when we are awake, whatever we decide to focus on may become conscious." Do you agree with this statement? If not, why not?@Mohammad & Jack,
I find little difference your respective observations, “Consciousness, which is expressed through the word “cognition”, is the mental activity and high brain functions that concern the processes of thought, decision-making and attention of a person”.
And, “I feel that consciousness is just an artefactual phenomena occurring as a result of the amalgamation of various cognitive modules.”
I recognise that term consciousness is used at least in half-a dozen meanings, but to say it is simply awareness and sense perception is to reduce this concept in its philosophical and mind-brain biological sense is too much.
However, as more clearly spelled by, if consciousness “occurring as a result of the amalgamation of various cognitive modules”, then it can be inferred it is an emergent property of life. Emergence is higher levels of complexity out of relatively simple biological processes or interactions. Life itself in Darwinian sense can be described as an emergent property of matter. Emergence is very often described as Gestalt which is well expressed in the phrase “The whole is greater than the sum of its parts.” Therefore, any reductionism is incapable of explain and reproducing or replicating it, for when units of biological material are put together, the properties of the new material are not always additive, or equal to the sum of the properties of the components. Instead, at each level, new properties and rules emerge that cannot be predicted by observations and full knowledge of the lower levels.
It can, therefore, like any emergence as in computers etc. may be analysed from within not without. If one analyses it from within, one can only find out “Cogito ergo sum” (I think, therefore I am) as Descartes did in the past.
To speak of consciousness loss due to disease, drugs or accident one cannot claim consciousness is lost because its discernible manifestation are not there. It is mentioned by Mohammad in a row, “Sleep is a change of consciousness; alcohol and drugs, hypnosis and meditation spoil consciousness”. Of course, alcohol and drugs drastically alter cells of brain, particularly size, however, it should be noted that unconscious poets under the influence of alcohol and drugs have uttered very famous couplets or poem. In the case of sleep, by sleep, I mean deep sleep to the extent of being unconscious, mothers are able to hear crying of their babies and take action according. In the case of hypnosis it should be noted that experiments have been reported that the subject can do ordinary harmless jobs under this condition, but the suggestion of murder or be ready to be raped make the subject wide awake. The rest rgarding hypnotism is fiction.Following
- Paul T. Evans added an answer:Do you believe there is an organ responsible for time experience?I do believe there is a connection between dopamine and time experience, however I do not think that it has anything to do with a physical structure in the brain. I believe that dopamine affects a person's ability to encode. The storage size metaphor (as suggested in Ornstein, 1942) states that a person's working memory and the amount of information put in is a better predictor of one's perception of time compared to any 'inner clock' mechanism (known). Also, studies have shown that depressed individuals (assuming low dopamine levels) encode more, suggesting a temporal 'stretching' which may be a factor in their depression. It may not be that they are encoding more, but that they cannot compress what they are encoding into smaller units because of their lack of dopamine. This may show a relationship between dopamine and encoding, which is the reason for dopamine's effect in temporal experience.In addition to frontal and parietal regions, deeper brain areas like the anterior cingulate and anterior insular cortex have also been implicated in timing and time perception.
In my view, scalar expectancy theory (SET) is a good explanation of how time perception results from expectation of reinforcement - at least in lower animals. In humans I think that time perception is a more complex process due to our more developed frontal lobe/ executive functions which are able to inhibit responses, allow us to plan for the future etc.

- Kadiri Tolani added an answer:What do you understand by Presidency Bashing?With an understanding of the psychological concept of aggression, can we explain the new-found behavior of presidency bashing?Presidency bashing is an aggressive tendency usually vented on the president of the federation due to the frustration of political or partisan goals. It can be best understood in the light of the frustration aggression theory.
In the Nigerian scenario, President Jonathan has been the one bearing the brunt of this aggressive behaviour. His ascent to power by providence irked a number of political players who are majorly from the Northern part of the country. The ruling class of the North strongly belief that they ought to be the one in power. The demise of the late president Yar'adua brought about a drastic change in the political equation of the country. Power suddenly shifted to a supposedly minority group and the ruling class of the North lost their political stake.
Jonathan's ascent into power also meant that a christian was in the reins again after former president Olusegun Obasanjo ruled for eight years. The dominant ruling class of the North who are largely muslims also felt irritated by the trend. Thus, President Jonathan has been lampooned severly by both critics and cynics.
A good number of politicians who have penchant for this aggressive behaviour include Femi Fani Kayode, Adamu Ciroma, Mallam Nasir El-Rufai just to mention a few.Following
- Gerard Derosiere added an answer:Can you recommend any papers on task load effects on vigilance performance?Please help me find articles in which 'task load' has been used as an independent variable on Vigilance Performance.Hi Tarun,
I would say that it depends on what you mean by "task load".
Some authors have indeed tested whether increasing the "task difficulty" by changing stimuli parameters (presentation rate, etc) would induce higher decrement in vigilance performance over time-on-task. In this vein, you should take a look at this paper: Smit, A. S., Eling, P. A., & Coenen, A. M. (2004). Mental effort causes vigilance decrease due to resource depletion. Acta psychologica, 115(1), 35-42.
According to these authors, increasing task difficulty is related to increasing task load.
However, this is worth mentioning that other authors have pointed out the paradoxical inverse relationship between the "task difficulty", and "task load" such as unchallenging, monotonous attention-related tasks are actually subjectively perceived more difficult and required more "cognitive effort" (Kahneman, 1973; Manly et al., 2003; Parasuraman, 1984; Poffenberger, 1927; Robinson and Bills, 1926; Wilkinson, 1964; see Robertson and O’Connell, 2010, for a recent review, or Langner and Eickoff, 2012).
Thus, according to these opposing views, increasing task difficulty could be associated with either an increase or a decrease in "task load".
