It makes sense that anxiety decreases mental functioning and performance. There is also probably going to be automatic amounts of worry and changing levels of motivation. The motivation shows an effort by the person to automatically try to decrease the anxiety or worry, which are more unconscious processes (because it is hard to control your anxiety or worry). Worry, motivation, and anxiety are going to take up resources and impact working memory (cognitive performance).

Eysenck and colleagues Eysenck, M. W., Derakshan, N., Santos, R., + Calvo, M.G. (2007). Anxiety and cognitive performance: Attentional control theory. Emotion, 7 (2), 336-353. recently extended the Processing Efficiency Theory to the more specific Attentional Control Theory. The Attentional Control Theory posits that anxiety, defined as a negative emotional and motivational state under threatening situations, affects cognitive performance by affecting two components of attentional control: top-down and stimulus-driven processes. Posner and Peterson Posner, M. I., + Peterson, S. E. (1990). The attention system brain. Annual Review of Neuroscience, 13, 25-42. described the top-down or goal-directed attentional system as the involvement of expectation and knowledge of current goals, while the stimulus-driven process involves detecting and responding to sensory events that are clear and obvious. The Attentional Control Theory states that anxiety disrupts the balance of goal-directed stimulus-driven processes by decreasing top-down processing and increasing stimulus-driven processing (Eysenck). Assimilating this information with Wegner's two-process theory, anxiety would decrease the operating process, which is conscious and goal oriented, and increase the monitoring process, which is automatic and stimulus driven. Anxiety reduces stimulus-driven processing by affecting the automatic processing of threat-related stimuli, but may also affect performance in any ongoing task. The rationale for this is that it would be harmful to the individual to focus on only threatening material; the best strategy would be for anxiety to affect attentional resources globally, not just towards threatening material. The idea is that anxiety may be affected by external and internal cues, with worry being an internal cue. Because anxiety involves emotion and arousal, it is important to understand how emotion and arousal, in general, affect cognitive control.

In my view, the theory is that anxiety decreases conscious thinking (such as goal-oriented thinking) and it increases sensory response (such as things you feel or just response to sensory stimulation). This makes sense to me, anxiety is going to make someone less conscious because it is an unconscious process itself. When you aren't thinking, you are going to be responding to the world more physically. Anxiety would thus actually increase your sensory response. For instance you might be faster physically - more aware of your body and your own condition. Anxiety is going to decrease your worrying or whatever it is you are thinking about because you have to deal with being anxious. At the same time, you are going to be at a higher state of alert, so you would respond faster to physical, sensory stimulation.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
