Contemporary Hollywood And The Attention Economy

This thesis had two goals: to explore the transformation of Hollywood from the 1930s to present, and to investigate how Contemporary Hollywood functions in a growing attention economy. Evident in the types of films that it produces as well as its evolving industrial structure, Contemporary Hollywood significantly differs from the Classical Hollywood of the 1930s. New digital technologies like surround sound and computer-generated imagery (CGI) have allowed studios to create a different type of film like the blockbuster and to have more extensive control over their films. Additionally, growing exhibition and distribution platforms have also fundamentally altered the industrial landscape of Hollywood. In order to combat this more egalitarian distribution system, Contemporary Hollywood has turned to conglomeratization. But, what has caused such a radical shift in the form and function of Contemporary Hollywood and its films? This thesis argues that Hollywood is failing to thrive in this new media landscape¿not because of changing technologies¿but because of a changing consumer. Richard Lanham theorizes that we are living in a growing attention economy, where human attention is the most valuable commodity in such an information-saturated society. For the current consumer, there is near-constant media over-stimulation: he or she is exposed to any number of screens (mobile phones, laptops, tablets, televisions, etc.) at any given time. Because we can access anything from anywhere at anytime, we¿ve become somewhat schizophrenic and impatient in terms of the media that we consume in our lives.

High-speed acousto-optic shutter with no optical frequency shift

Acousto-optic modulators are widely used for rapid switching and shuttering of laser beams. In many applications, the concomitant frequency shift is undesirable and must be compensated for elsewhere in the system. Here we present a simple method of achieving rapid laser power switching without an accompanying laser frequency shift. The demonstrated acousto-optic shutter achieves a switching time of around 25 ns, an extinction ratio of 46 dB, and efficiency comparable to a conventional double-pass acousto-optical modulator configuration.

The Effects of Emotions and Distraction on Attention During a Perceptual Task

According to the broaden-and-build theory of positive emotions, positive emotions broaden while negative emotions narrow thought-action repertoires. These processes reflect changes in attentional scope, which is the focus of this research. The present study tested the hypothesis that participants in negative mood would be better able to focus on a target figure and separate it from its context in a perceptual task, and would also be better able to focus on the task amid a distracting environment than participants in a positive mood. An undergraduate sample of 77 participants watched video clips selected to induce either fear or amusement, and completed an Embedded Figures Test either in a quiet setting or in a noisy setting. A higher-order ANOVA revealed that Mood had a marginally significant effect on task performance, F(1, 73) = 3.94, p = .051, and that Distraction, F(1, 72) = 4.61, p = .035 and the Mood x Distraction interaction, F(1, 73) = 9.12, p = .003 did significantly affect task performance. However, contrary to the hypothesis, the effect of the distraction manipulation was greater for participants in a negative mood than it was for participants in a positive mood. The author suggests future directions to clarify the relationship between emotions, attentional scope, and susceptibility to environmental distraction.
