It is not too late, but about time to realize how damaging IT overuse can be. The present paper discusses why it of tremendous importance study the effect Internet, smartphone, and other new digital technologies on individuals' productivity well-being. Besides its recognized addictive nature, also becomes clear that such technology inevitably alters our natural social lives, which has, in opinion, potential harm entire societies. In developed countries, we are more or less all using devices...

On the 10th anniversary of NeuroIS field, we reflect on accomplishments but, more importantly, future field. This commentary presents our thoughts a research agenda with potential for high impact societal contributions. Four key areas information systems (IS) are: (1) IS design, (2) use, (3) emotion research, and (4) neuro-adaptive systems. We challenges each area provide specific questions that serve as important directions advancing The supports fellow researchers in planning, conducting,...

With this study we wanted to test the hypothesis that individual like and dislike as occurring in relation brand attitude can be objectively assessed. First, individuals rated common brands with respect subjective preference. Then, they volunteered an experiment during which their most liked disliked names were visually presented while three different objective measures taken. Participant's eye blinks responses acoustic startle probes registered electromyography (EMG) (i) skin conductance...

In the current study, electroencephalography (EEG) was recorded simultaneously with facial electromyography (fEMG) to determine whether emotional faces and scenes are processed differently at neural level. addition, it investigated these differences can be observed behavioural level via spontaneous muscle activity. Emotional content of stimuli did not affect early P1 elicited enhanced amplitudes face-sensitive N170 component, while its counterpart, scene-related N100, sensitive scenes. At...

Consumers' attitudes towards established brands were tested using implicit and explicit measures. In particular, late positive potential (LPP) effects assessed as an neurophysiological measure of motivational significance. The Implicit Association Test (IAT) was used behavioural valence-related aspects (affective content) brand attitude. We constructed individualised stimulus lists liked disliked types from participants' subjective pre-assessment. Participants then re-rated these visually...

The neuroscience of language processing in the human brain has a long history. Strings letters that form meaningful words trigger lexical and semantic processing, which turn lead to conscious awareness what mean. However, it is still unclear how processes normal differently from number and, more interestingly, digits, both are meant quantity processing. While much literature deals with this topic, time course respective differences activity been largely ignored. This may be because most...

Previous studies were able to demonstrate different verbally stated affective responses environments. In the present study we used objective measures of emotion. We examined startle reflex modulation as well changes in heart rate and skin conductance while subjects virtually walked through six areas urban Paris using StreetView tool Google maps. Unknown subjects, these selected based on their median real estate prices. First, found that price highly correlated with subjective rating...

Does a bottle elicit gender-specific emotion response that varies as function of its shape? The answer to this question is basic interest well specific the industry. We introduced startle reflex modulation objectively measure emotion-related aspects different bottles. This approach was chosen complete behavioural data with objective physiological data. Three bottles differing only in shape were used test stimuli. It known magnitude an eye blink acoustic stimulation reflects current elicited...

This study is based on the idea that emotion-related processing happens various different levels. Common methods are used to measure aspects of exhibit specific sensitivities one or other these separate Here, hypothesis was tested explicit and implicit measures differently influenced by self-referenced versus unreferenced emotion. The self reported valence startle reflex modulation. In session, emotional scenes were paired with short sentences inducing self-reference (e.g. "this dog will...

Two experiments investigate effects related to food intake in humans. In Experiment 1, we measured startle response modulation while study participants ate ice cream, yoghurt, and chocolate. Statistical analysis revealed that cream resulted the most robust inhibition compared no food. Contrasting females males, found significant differences conditions yoghurt females, chocolate elicited lowest amplitude followed by cream. produced highest even higher than eating nothing, whereas lowest....
