Three mediational theories of anxiety and performance, namely, cue utilization theory (Easterbrook, 1959), attentional theory (Mandler & Sarason, 1952; Wine, 1971), and working memory capacity theory (M. W. Eysenck, 1979), were compared for their efficacy in explaining anxiety-induced performance decrements on a task of analogical reasoning. One hundred two subjects who varied in their trait an...

We investigate the age-limited capacity of Gaussian many channel with total $N$ users, out which a random subset notation="LaTeX">$K_{a}$ users are active in any transmission period, and large-scale antenna array at base station (BS)....

Selective attention enables enhancing a subset out of multiple competing items to maximize the capacity of our limited visual working memory (VWM) system. Multiple behavioral and electrophysiological studies have revealed the cognitive and neural mechanisms supporting adults' selective attention of visual percepts for encoding in VWM. However, research on children is more limited. What are the ...

We consider a Bayesian persuasion problem where the persuader and the decision maker communicate through an imperfect channel which has a fixed and limited number of messages and is subject to exogenous noise. Imperfect communication entails a loss of payoff for the persuader. We establish an upper bound on the payoffs the persuader can secure by communicating through the channel. We also show ...

Abstract We study a variation of the duopoly model by Kreps and Scheinkman (1983). Firms limited their capacity production engage in two stage game. In first they commit to levels not exceeding capacities which are then made common knowledge. second after has taken place firms simultaneously compete prices. Solution this sequential game shows that unique Cournot equilibrium outcome as is always...

While counting objects is typically a slow, serial process, enumerating about four or fewer objects has been considered to be a relatively effortless, parallel, and even preattentive process often referred to as subitizing. However, by combining a subitizing task with an attentional blink task, we show that subitizing is systematically affected by a closely preceding letter identification task....

Visual extinction was studied in a patient with neglect from a right hemispheric lesion. Extinction occurred during double simultaneous stimulation within the same visual hemi-field (VHF). This finding suggests that interhemispheric rivalry is not a critical factor. During double simultaneous stimulation within the same VHF as well as with stimuli in different VHFs, the severity of extinction w...

This paper reports the findings from a study that explored effects of task complexity on linguistic in EFL writing with within-and-between-subject design for sustainability skills. A total 178 English majors and non-English participated study. They each performed two tasks were manipulated using variables: number elements prior knowledge. Linguistic was measured both syntactic lexical aspects 3...
