Measured Preference

59 students in architecture and 50 medical students were compared using two questionnaire-defined measures of cognitive style. The Inquiry Mode Questionnaire (InQ) measured cognitive style according to five major dimensions: synthesist, idealist, analyst, realist and pragmatist. Your Style of Learning and Thinking (SOLAT)—Form C, now published as the Human Information Processing Survey (HIP Survey), measured preference for one of three main styles: a visuospatial, nonlinear, holistic, right-brain style; a verbal, analytic, sequential, left-brain style; and an integrated style involving an integration of the right and left styles. Significant differences were found for the two groups on the two questionnaires. Students in architecture favored the idealist style on the InQ and right-brain style on the SOLAT. Medical students favored the realist style on the InQ and the left-brain style on the SOLAT. Association between the InQ synthesist-idealist combined scores and the SOLAT inferred right-brain style and between the InQ analyst-realist style and the SOLAT left-brain style were observed.

Voice Response

Interactive Voice Response (IVR) is an automated telephony system that interacts with callers, gathers information and routes calls to the appropriate recipient. An IVR system (IVRS) accepts a combination of voice telephone input and touch-tone keypad selection and provides appropriate responses in the form of voice, fax, callback, e-mail and perhaps other media.  In recent years, many enterprises use IVR as their customer service media. Some problems arise as user problems, that is user have to remembering the too many choices; user does’nt achieve what  they want (did not find the right choices); and the worst is tiring finding choices yet they have not find the human operator. This paper will observe the effect of message structuring for IVR customer satisfication. Human information processing (especially audio-based information) theory as well as menu organizing theory will be used as analysis fundamentals. Questionnaire will be distributed to IVR users to grab the real user experience<strong>.</strong>

Efficient Information

Using grounded theory along with participant observation and interviews the authors explore how individuals in organizations process information. They build a model of human information processing which links the cognitivist-constructionist perspective to an algorithmic-heuristic continuum. They test this model using non-parametric procedures and find interesting results showing links to efficient information processing outcomes such as contributions to decision-making, knowledge-creation and innovation. They also identify some elements of best practice by efficient human information processing individuals whom they call the “information catalysts”.

Rate Information

Previous research investigating base rate neglect as a bias in human information processing has focused on isolated individuals. This study complements this research by showing that in settings of interacting individuals, especially in settings of social learning, where individuals can learn from one another, base rate neglect can increase a population's welfare. This study further supports the research arguing that a population with members biased by neglecting base rates does not need to perform worse than a population with unbiased members. Adapting the model of social learning suggested by Bikhchandani, Hirshleifer and Welch (The Journal of Political Economy100 (1992) 992–1026) and including base rates that differ from generic cases such as 50–50, conditions are identified that make underweighting base rate information increasing the population's welfare. The base rate neglect can start a social learning process that otherwise had not been started and thus base rate neglect can generate positive externalities improving a population's welfare.

Norepinephrine System

Several lines of evidence suggest that there is a close interrelation between the degree of noise in neural circuits and the activity of the norepinephrine (NE) system, yet the precise nexus between these aspects is far from being understood during human information processing and cognitive control in particular. We examine this nexus during response inhibition in n = 47 healthy participants. Using high-density EEG recordings, we estimate neural noise by calculating “1/ f noise” of those data and integrate these EEG parameters with pupil diameter data as an established indirect index of NE system activity. We show that neural noise is reduced when cognitive control processes to inhibit a prepotent/automated response are exerted. These neural noise variations were confined to the theta frequency band, which has also been shown to play a central role during response inhibition and cognitive control. There were strong positive correlations between the 1 /f neural noise parameter and the pupil diameter data within the first 250 ms after the Nogo stimulus presentation at centro-parietal electrode sites. No such correlations were evident during automated responding on Go trials. Source localization analyses using standardized low-resolution brain electromagnetic tomography show that inferior parietal areas are activated in this time period in Nogo trials. The data suggest an interrelation of NE system activity and neural noise within early stages of information processing associated with inferior parietal areas when cognitive control processes are required. The data provide the first direct evidence for the nexus between NE system activity and the modulation of neural noise during inhibitory control in humans. NEW & NOTEWORTHY This is the first study showing that there is a nexus between norepinephrine system activity and the modulation of neural noise or scale-free neural activity during inhibitory control in humans. It does so by integrating pupil diameter data with analysis of EEG neural noise.
