comment Why does repeating one word over and over again sound weird to us after some time?
speculative: words only have meaning holistically and in context, if you reduce them they're just sounds. The more you say a word over and over, the more I think you lose context about it and your brain starts to focus on the reductionist aspects of it. Brains get bored with repetitive stimulus so reinterpreting a persistent stimulus might do something to avoid that boredom.

yes you're right, edited.

comment Why do people want what they don't have now?
If had time I'd provide a more referenced answer, but once seeking behavior is procedural, dopamine responses become linked with the procedure of seeking itself (and then there's a let down if the object is not found).

comment What neurological processes occur with 'revulsion'?
I remember reading that disgust, even if social or visual, had a lot of overlap in activity patterns with the same circuits involved in physiological nausea.

comment As for future mind control/reading technology, can humans fight it?
It depends. If a "lower" function is hijacked, it may be able to be overridden by regions that retain control "upstream" in the control flow. If the "higher level" functions are actually being hijacked, I don't see how there's much you could do. Of course, this is speculation, but I think that due to the numerous ways ways in which individual brains can retain information, a certain amount of training would be required to get the machine and the brain to interface (whether brain->machine or machine->brain). Thus, it would require some obvious intrusions on privacy.

comment Is multitasking a myth?
I can't guarantee that I'll have time to be more thorough anytime soon, or I'd make it an official answer with references. If I find time, I'll do so, but I welcome anyone else to dig up the resources (I'd probably just go to google and/or google scholar myself).

comment Is multitasking a myth?
I think it depends on how you define multi tasking. Certainly we can listen to words while we watch the mouth, processing two different streams and integrating them. But if you play two different audio streams into the ears, most people can only focus on one of them at a time. With a little bit of practice, one can pat the head as they rub the belly. There was a study that showed that office multitaskers made significant sacrifices to work quality. Another study shows worse reaction times for drivers when they are on the cell phone.

comment What biological processes occur when you love someone romantically?
I don't think love is just a biological process. Its also a social process: the idea of love itself has many socially defined/described aspects (magazines, movies, friends) thay set expectations for the party's involved. Of course, the biological aspect (attraction?) is also there.

comment How long should I work before taking a break?
this seems like something that would vary greatly from person to person and job to job. Unfortunately, statistical averaging of large groups can obscure this kind of information.

comment In a central pattern generator based on reciprocal inhibition, how does one “side” get picked over the other to start out?
I would call it signal, not noise. But I think you could anyway improve your answer a lot...

comment In a central pattern generator based on reciprocal inhibition, how does one “side” get picked over the other to start out?
I down-voted this answer. Noise does inject assymetry into the system. However, a much stronger, system-regulated mechanism of assymetey is connection strength. This can come in the form of 1) number of interconnections, 2) regulation of the amount of neurotransmitter released 3) autoregulation of a specific cell 4) regulation of neurotransmitter receptor density 5) other connections or astrocytes or even local environment regulating the excitability of individual cells.

comment What is the difference between psychophysics and neurophysiology?
I would say neurophysiology also included emergent behavior, like breathing or heartbeat, not just underlying anatomical structure. That's essentially the difference: psychophysics (as you say) pertains to subjective experience, while neurophysiology pertains to objective processes.

comment Do victims of parental abuse and neglect become abusive or neglectful parents?
I feel like "bad parenting" is a very arbitrary term... maybe you could e more specific for each example.

comment What causes an individual to not be able to hold all the details of a large project in memory?
sounds like "seeing the forest for the trees" or the "Gestalt" of it all. The "big picture". These are all terms we use in society, anyway. Not sure of the formal psychology term. I think your question could be more concise and include initial research once we find it, though.

comment Training for the corpus callosum?
there's a left and right field in each eye. but regardless, the point is that it all goes through left hemisphere for interpretation, after being visually encoded

comment Training for the corpus callosum?
As the first comment reply to your question implies, your visual field is not correlated to left-brain text-interpretation in that way. If the text is seen by the whole field, it goes through both occipital lobes (on both sides of the brain) and then from occipital lobes, goes to the left hemisphere. It would be the same if you used only used a single field. It doesn't matter what visual field it enters through, it still goes to the left cortex for interpretation.

comment Intelligence and marriage satisfaction
I wonder what would happen if one controlled for "meeting in college". Assuming people in college are more intelligent by the IQ measure, then a contributing factor may be two intelligent people just being in the same place at the same time, rather than an attraction to intelligence. Just a thought.

comment Should questions in psychology always be objective questions?
Color perception and taste can be an important aspect of psychology. It's more on the cognitive scientific side than the clinical medical side, but its still science. Think of it as asking a rock how fast it falls then asking a feather. You get different answers, but you're still asking scientific questions.
