Emotion and Adaptation

A study of Kant’s Critique of Judgment (1790). Our topics will include Kant’s motivations for a critique of judgment; principles of ‘reflective’ and ‘determining’ judgment; theory of aesthetic judgment, including epistemology and metaphysics of the beautiful and sublime; theory of genius; teleology in the critical philosophy—including harmony of the cognitive faculties, organisms, scope and limits of mechanical explanation, physicoand ethico-theology; the relation of ethics, aesthetics and teleology. A basic familiarity with Kant’s theoretical philosophy is presupposed.

Critique of Judgment

Every design problem begins with an effort to achieve fitness between two entities: the form in question and its context. The form is the solution to the problem; the context defines the problem. We want to put the context and the form into effortless contact or frictionless coexistence, i.e., we want to find a good fit. For a good fit to occur in practice, one vital condition must be satisfied. It must have time to happen. In slow-changing, traditional, unselfconscious cultures, a form is adjusted soon after each slight misfit occurs. If there was good fit at some stage in the past, no matter how removed, it will have persisted, because there is an active stability at work. Tradition and taboo dampen and control the rate of change in an unselfconscious culture's designs. It is important to understand that the individual person in an unselfconscious culture needs no creative strength. He does not need to be able to improve the form, only to make some sort of change when he notices a failure. The changes may not always be for the better; but it is not necessary that they should be, since the operation of the process allows only the improvements to persist. Unselfconscious design is a process of slow adaptation and error reduction. In the unselfconscious process there is no possibility of misconstruing the situation. Nobody makes a picture of the context, so the picture cannot be wrong. But the modern, selfconscious designer works entirely from a picture in his mind - a conceptualization of the forces at work and their interrelationships - and this picture is almost always wrong. To achieve in a few hours at the drawing board what once took centuries of adaptation and development, to invent a form suddenly which clearly fits its context - the extent of invention necessary is beyond the individual designer. A designer who sets out to achieve an adaptive good fit in a single leap is not unlike the child who shakes his glass-topped puzzle fretfully, expecting at one shake to arrange the bits inside correctly. The designer's attempt is hardly as random as the child's is; but the difficulties are the same. His chances of success are small because the number of factors which must fall simultaneously into place is so enormous. The process of design, even when it has become selfconscious, remains a process of error-reduction. No complex system will succeed in adapting in a reasonable amount of time or effort unless the adaptation can proceed component by component, each component relatively independent of the others. The search for the right components, and the right way to build the form up from these components, is the greatest challenge faced by the modern, selfconscious designer. The culmination of the modern designer's task is to make every unit of design both a component and a system. As a component it will fit into the hierarchy of larger components that are above it; as a system it will specify the hierarchy of smaller components of which it itself is made.

Recent developments and studies in brain-computer interface (BCI) technologies have facilitated emotion detection and classification. Many BCI studies have sought to investigate, detect, and recognize participants’ emotional affective states. The applied domains for these studies are varied, and include such fields as communication, education, entertainment, and medicine. To understand trends in electroencephalography (EEG)-based emotion recognition system research and to provide practitioners and researchers with insights into and future directions for emotion recognition systems, this study set out to review published articles on emotion detection, recognition, and classification. The study also reviews current and future trends and discusses how these trends may impact researchers and practitioners alike. We reviewed 285 articles, of which 160 were refereed journal articles that were published since the inception of affective computing research. The articles were classified based on a scheme consisting of two categories: research orientation and domains/applications. Our results show considerable growth of EEG-based emotion detection journal publications. This growth reflects an increased research interest in EEG-based emotion detection as a salient and legitimate research area. Such factors as the proliferation of wireless EEG devices, advances in computational intelligence techniques, and machine learning spurred this growth.

In recent years, neuroscientific knowledge has been applied to marketing as a novel and efficient means to comprehend the cognitive and behavioral aspects of consumers. A number of studies have attempted to evaluate media contents, especially TV commercials using various neuroimaging techniques such as electroencephalography (EEG). Yet neurophysiological examination of detailed cognitive and affective responses in viewers is still required to provide practical information to marketers. Here, this study develops a method to analyze temporal patterns of EEG data and extract affective and cognitive indices such as happiness, surprise, and attention for TV commercial evaluation. Twenty participants participated in the study. We developed the neurophysiological indices for TV commercial evaluation using classification model. Specifically, these model-based indices were customized using individual EEG features. We used a video game for developing the index of attention and four video clips for developing indices of happiness and surprise. Statistical processes including one-way analyses of variance (ANOVA) and the cross validation scheme were used to select EEG features for each index. The EEG features were composed of the combinations of spectral power at selected channels from the cross validation for each individual. The Fisher’s linear discriminant classifier (FLDA) was used to estimate each neurophysiological index during viewing four different TV commercials. Post hoc behavioral responses of preference, short-term memory, and recall were measured. Behavioral results showed significant differences for all preference, short-term memory rates, and recall rates between commercials, leading to a ‘high-ranked’ commercial group and a ‘low-ranked’ group (P < 0.05). Neural estimation of happiness results revealed a significant difference between the high-ranked and the low-ranked commercials in happiness index (P < 0.01). The order of rankings based on happiness and attention matched well with the order of behavioral response rankings. In the elapsed-time analysis of the highest-ranked commercial, we could point to visual and auditory semantic structures of the commercial that induced increases in the happiness index. Our results demonstrated that the neurophysiological indices developed in this study may provide a useful tool for evaluating TV commercials.

Designing for Positive Emotions: Issues and Emerging Research Directions

The paper reports a study into consumers’ ‘soft’ usability problems they experience using electronic household products. These problems cannot be traced back to a specification violation failure, classified as no failure found (NFF). The aim of this study is to find a relationship between consumers’ soft usability problems and their personal characteristics, encompassing demographical and cognitive aspects. The complaints collected through an exploratory survey were classified into three categories of soft usability problems. The findings indicate that demographic, socioeconomic and cultural characteristics as well as personal traits show significant correlations with these problem categories. Based on the data preliminary user profiles were made. By providing a new definition of usability problems and by user profiling, this study is expected to help design teams to get a better understanding of their target group. The implications of these findings for the product development process are discussed.

Recent attention has been given to the role of emotion regulation in promoting well-being. Although various approaches have been established to design for emotion in design research and HCI, there is only little knowledge on how to support the process of regulating user emotions through design. The paper introduces a framework that delineates 17 emotion regulation strategies based on the theories of emotion regulation. The framework supports an understanding of emotion regulation strategies by enabling designers to compare differences and overlaps of the strategies. The paper describes the framework and its development process along with design examples. Implications and future research steps are discussed.
