“…The construction of the objects used in our studies allowed the precise determination of the bit values of each of the objects using Shannon's formula (Shannon, 1948;Lehrl, & Fischer, 1988): M = -log 2 p. M is the number of bits per sign, and p is the probability of choosing the sign from the pool. The bit values for the particular objects in the experiments were the following: "4 out of 2" (4 bits), "4 out of 3" (6.3 bits), and "4 out of 4" (7.9 bits).…”

The present study was based on the hypothesis that a limited amount of information can be simultaneously processed in working memory. The main objective was to determine the capacity of working memory under experiment conditions and express it in terms of bits of information. The bit values of the selected objects used in the experiment were determined using Shannon's formula. The objects were presented to the participants as a set of charts. Each chart presented a four-element object with a particular bit value. The elements constituted commonly known signs, with no difficulty in perception. The efficiency of object recollection from working memory decreased as the bit value of the object increased. In each of the experiments, the bit value of the recollected information oscillated between 26.7 and 31.9. The present results did not confirm sex differences in working memory function.

“…The working memory capacity that consists of both measured basic parameters of information processing (rate of information processing and length of memory span) will increase between TA2 and TA3. If this hypothesis is affirmed, the same change applies to the fluid IQ, which is based on the assignment of the working memory capacity to a Gaussian distribution of mental performance [4][5]. 2.…”

“…• We used the Kurztest fur Allgemeine Intelligenz, a short test for basic parameters of central information processing, to measure the rate of information processing (bits per second) and the length of memory span (seconds or chunks [i.e., units in mind such as letters, digits, or one-syllable words]) [4][5]. This test assesses working memory capacity (bit), which is the product of the two basic parameters of central information processing.…”

Abstract-Prolonged hospitalization is known to be associated with a loss of cognitive performance. Does playing video games (VGs) developed to improve cognitive properties delay this loss or even lead to an increase in cognitive performance? We performed a 10-day longitudinal study of patients who received total hip arthroplasty. We compared 16 patients (6 male) aged 66 ± 9 years (mean ± standard deviation) who played Dr. Kawashima's Brain Training: How Old Is Your Brain? (Nintendo; Redmond, Washington) on a Nintendo DS handheld console with 16 control patients (6 male) aged 69 ± 14 years. We measured cognitive performance 1 day preoperation, as well as on days 2 and 9 postoperation. With the daily exercise of a specific VG by the play group, the patients' fluid intelligence (median intelligence quotient 99-106), working memory capacity, and rate of information processing significantly improved over the course of 7 postoperative days. The cognitive performance of the control group did not increase. However, the memory spans of both groups did not systematically change. Exercise with VGs can prevent the loss of cognitive performance during prolonged hospitalization.

“…From the perspective of external inputs, a human operates in five principal outward facing sensory domains -visual, auditory, tactile, olfactory, and taste, as well as in a number of inward-facing sensory domains [4]. There are a number of models of how sensory inputs end-up being processed, become actionable and possibly become memories, and there is a huge amount of literature regarding the human mind, its capabilities, and its limits.…”

A Note on Uncertainty in Real-Time Analytics

Abstract. Today real-time analytics of large data sets is invariably computer-assisted and often includes a "human-in-the-loop". Humans differ from each other and all have a very limited innate capacity to process new information in real-time. This introduces statistical and systematic uncertainties into observations, analyses and decisions humans make when they are "in the loop". Humans also have unconscious and conscious biases, and these can introduce (major) systematic errors into human assisted or human driven analytics. This note briefly discusses the issues and the (considerable) implications they can have on real-time analytics that involves humans, including software interfaces, learning, and reaction of humans in emergencies.
