Crap, cosmos...

Developmental instability predicts individual variation in verbal memory skill after caffeine ingestion.

OBJECTIVE: To determine the mediating effects of developmental instability on individual differences in response to caffeine. BACKGROUND: Individual variation of drug effects might reflect broad genomic factors as well as the direct effects of specific alleles. The current study tested the hypothesis that individual differences in developmental instability, in part determined by genomic characteristics, would predict individual variation in the magnitude of caffeine-induced verbal memory deficits. Minor physical anomalies and fluctuating asymmetry were used as measures of developmental instability. METHOD: One hundred participants were (1) administered one version of the Rey Auditory Verbal Learning Test; (2) given a dose of caffeine determined by body weight (3 mg/kg); (3) assessed for minor physical anomalies and fluctuating asymmetry; and (4) given an alternate randomized version of the Rey Auditory Verbal Learning Test. RESULTS: Consistent with predictions, a composite measure of developmental instability predicted the magnitude of caffeine-induced memory decrements. CONCLUSIONS: These results may have important implications for the genetic underpinnings of individual differences in drug effects.

Of course, there could be contradictory studies. I queried "caffeine verbal" in Google Scholar for this one in particular. And I could be misinterpreting it too. Time pressure, regardless of anything else, tends to have a negative impact on verbal fluency when caffeine-induced.

Specifically at home or anywhere that you may be taking a cup ?

The source of this problem could in part be derived from temporary memory deficits, but I hesitate to offer that as evidence because it may largely be the product of confirmation bias when presented with this study.

Maybe. But what would be the source of the temporary memory deficits?

It was my consistently diminished oral verbal fluency while participating in one of my afternoon classes, that led me to create this thread.

"Verbal" can imply 'oral' though.

Also, by chance have you tried not having the coffee while all else is equal?

Reason for my question, is nowadays ceramic glazes contain several elements which have the potential to leach into food or beverages. Recently, barium salts have been investigated as one of the alternatives to lead in frit formulations for glazes, Barium is a trace element which can apparently affect thyroid function and which may be especially toxic for persons with thyroid disease, especially hyperthyroidism, Barium is also used as rat poison. This works by interfering with the sodium-potassium pump and causing a paralysis of the muscles, including the heart muscles and respiratory muscles, causing death.

Because barium interferes with the sodium-potassium pump, which seems already disturbed in hyperthyroidism, any ingestion of barium may be very toxic to someone with hyperthyroidism (or anyone for that matter).

It would be interesting to find out if any one that goes with the same consumption has related effects as yours.

All right then, cosmos. I hope some more answers are forthcoming.

Yea this is quite interesting, coffee is really a double-edged sword, - at low dosing (1-2 cups a day - or for some, 1/2 cup) I think it has several positive effects (including a taste actually!) but many people habitually wash down *jugs* fighting through the day.
Cosmos you're right on with your experience with coffee.
Experiencing anxiety takes the fun out of everything, including sabotaging ones ability to communicate crystal-clearly with a settled, calm yet very awake mind.

There aren't too many rational lifeways that can accommodate failure after failure after, perhaps, critical failure, but if you're fortunate enough to find and choose one, cosmos, I think that would be progress in this kind of situation. If that isn't a feasible solution, perhaps more exercise and better nutrition need to be incorporated. If done right, plus getting priorities straight in general (not easy, granted), this should improve your sleeping patterns and general mood. In turn, that reduces the perceived need for caffeine on a regular basis.

I'm just throwing things out there. I can only speculate what's going on.

Hmm, that could be interpreted multiple ways, some of them the wrong way as to be offensive. It's not meant to be. To avoid further unsolicited preaching, however, I'll just leave it at that.

After caffeine use, my verbal fluency is greatly increased for a few hours. If you get nervous or get anxiety attacks from caffeine then dont use it anymore. Caffeine decreases my anxiety.

[salesman]

Shoot I shouldnt have read this thread now that I drank a cup of coffee it totally diminished the effect of my adderall must be in my head who knows?

[salesman]

Anyone know how to find out how to benefit by adderall with out other interactions from food, or ph levels in the stomach? What diminishes the effects? My doctor told me that consumption of fats inhibited absorption of adderall

[Kalepha]

It seems a bit unclear what you're searching for, cosmos. That caffeine can aggravate anxiety, and that anxiety can negatively affect expected behavior, can easily be corroborated. Perhaps you need qualified professionals to help you treat the anxiety. And if not, your ideals probably far exceed your inherent biological capabilities anyway, such that you could go on forever with this belief in having a verbal fluency deficit until the plain and simple truth is that you need radical IA.

I have a few options to explore before seeking professional help, my lifestyle may turn out to be a significant contributing factor. Should those changes fail to produce the desired result within me, I'll pursue professional help.

I'm sure it'll all work out.

I was never a fluent public speaker, but sporadically I still demonstrate a level of verbal fluency more consistent with my expectations.

These expectations, I imagine, aren't supererogatory for the circumstances. You still need to function for the time being.
