Digital Transformation and Disruptive Management

The digital transformation disruptive on music industry in South Korea expresses objectives are to study risk and disruptive technology on an impact in the music businesses; also, how Korean music industry manages during in the digital era. Besides, using risk theory, demand and supply theory, including disruptive information to support. Methods are used mostly via qualitative data. The result finds from risk that has affected both consumers and producers. Companies and labels in music industry may lose incomes and powers to control the market. Consumers may pay much costs to consume products. On the other hands, consumers have varieties of channels to access in music. Moreover, South Korea adopts and creates the developed technological products to survive in digital age. Technology and digital transformation in music industry have both advantages and disadvantages to the role of people who play in this field. To cope with the changes, industry needs to develop and adapt itself on surviving and handling the competition from more competitors and technology. They should find an approach to adapt, continue and develop an efficiency in the manufacturing sector such as seeking strategies to grasp market, generate another source of revenues by viewing both competitors and partners. Opening minds to challenges for deploying, launching, digitizing, and modernizing the new digital capabilities deeply on how distribution network be integrated into the music industry transformation process to interact with the customers. Because the digital transformation has appeared as a key press in society rather than an option from now on. Keywords: Digital, Disruptive, Music, South Korea, Transformation

The Integration of Eye Tracking Responses for the Measurement of Contrast Sensitivity: A Proof of Concept Study

Contrast sensitivity (CS) is important when assessing functional vision. However, current techniques for assessing CS are not suitable for young children or non-verbal individuals because they require reliable, subjective perceptual reports. This study explored the feasibility of applying eye tracking technology to quantify CS as a first step toward developing a testing paradigm that will not rely on observers’ behavioral or language abilities. Using a within-subject design, 27 healthy young adults completed CS measures for three spatial frequencies with best-corrected vision and lens-induced optical blur. Monocular CS was estimated using a five-alternative, forced-choice grating detection task. Thresholds were measured using eye movement responses and conventional key-press responses. CS measured using eye movements compared well with results obtained using key-press responses [Pearson’s rbest–corrected = 0.966, P < 0.001]. Good test–retest variability was evident for the eye-movement-based measures (Pearson’s r = 0.916, P < 0.001) with a coefficient of repeatability of 0.377 log CS across different days. This study provides a proof of concept that eye tracking can be used to automatically record eye gaze positions and accurately quantify human spatial vision. Future work will update this paradigm by incorporating the preferential looking technique into the eye tracking methods, optimizing the CS sampling algorithm and adapting the methodology to broaden its use on infants and non-verbal individuals.

Exceptional Times, Emergency Borders

Chapter 2 examines the role of elite governmental actors in producing the narrative of the so-called 2015 ‘migration crisis’ and creating the conditions under which walling and deterrent border security policies flourished. The first part of the chapter draws on key press releases, speeches, and policy documents issued by the EU Commission and its agencies in order to map the emergence and trajectory of this elite ‘crisis’ narrative from the so-called ‘ghost ship’ arrivals to the height of ‘irregular’ arrivals that year. The second part shows how this ahistorical, Euro-centric, and (post)colonial governmental frame—with its reductionist depiction of mobile populations and sanitized one-sided view of border-related violence—has been problematized and disaggregated by research that documents the experiences of those seeking entry to the EU. The third part draws on theoretical literatures on the politics of crisis in order to argue that, irrespective of its empirical accuracy, the so-called ‘crisis’ narrative has enabled the intensification of deterrent border security measures on- and off-shore and the re-emergence of disciplinary walling techniques among EU Member States in ways that would be otherwise unpalatable in liberal democracies during ‘non-crisis’ times. But while extant work on crisis enables a critical analysis of the politics of ‘crisis bordering’ that is essential for any attempt to grapple with the book’s overarching puzzle, ultimately it falls short of explaining why populist calls to ‘take back control’ have been stoked rather than satiated by such bordering and therefore it is necessary to investigate those calls—and their reception—among diverse publics in closer detail.

Multiplicative priming of the correct response can explain the interaction between Simon and flanker congruency

In the Simon task, participants perform a decision on non-spatial features (e.g., stimulus color) by responding with a left or right key-press to a stimulus presented on the left or right side of the screen. In the flanker task, they classify the central character while ignoring the flanking characters. In each task, there is a conflict between the response-relevant features and the response-irrelevant features (i.e., the location on the screen for the Simon task, and the flankers for the flanker task). Thus, in both tasks, resolving conflict requires to inhibit irrelevant features and to focus on relevant features. When both tasks were combined within the same trial (e.g., when the row of characters was presented on the left or right side of the screen), most previous research has shown an interaction. In the present study, we investigated whether this interaction is affected by a multiplicative priming of the correct response occurring when both Simon and flanker irrelevant features co-activate the correct response (Exp. 1), a spatial overlap between Simon and flanker features (Exp. 2), and the learning of stimulus-response pairings (Exp. 3). The results only show an impact of multiplicative priming.

Choices in a key press decision-making task are more optimal after gaining both aiming and reward experience

When presented with two different target–penalty configurations of similar maximum expected gain (MEG), participants prefer aiming to configurations with more advantageous spatial, rather than more advantageous gain parameters—perhaps due to the motor system’s inherent prioritisation of spatial information during movements with high accuracy demands such as aiming. To test this hypothesis, participants in the present studies chose between target–penalty configurations via key presses to reduce the importance of spatial parameters of the response and performance-related feedback. Configurations varied in spatial (target–penalty region overlap) and gain parameters (negative penalty values) and could have similar or different MEG. Choices were made without prior aiming experience (Experiment 1), after aiming experience provided information of movement variability (Experiment 2), or after aiming experience provided information of movement variability and outcome feedback (Experiment 3). Overall, configurations with advantageous spatial or gain parameters were chosen equally (Both-Similar condition) in all experiments. However, average behaviour at the group level was not reflective of the behaviour of most individual participants with three subgroups emerging: those with a value preference, distance preference, or no preference. In Experiments 1 and 2, these individual differences cannot be explained by MEG differences between configurations or participants’ movement variability, but these variables predicted choice behaviour in Experiment 3. Further in the Both-Different condition, participants only selected the larger MEG configuration at a level above chance when both variability and outcome information were given prior to the key press task (Experiment 3). In sum, the data indicate that prioritisation of spatial information did not emerge at the group level when performing key presses and more optimal behaviour emerged when information regarding movement variability and outcome feedback were given.

Mouse Tracking to Explore Motor Inhibition Processes in Go/No-Go and Stop Signal Tasks

Response inhibition relies on both proactive and reactive mechanisms that exert a synergic control on goal-directed actions. It is typically evaluated by the go/no-go (GNG) and the stop signal task (SST) with response recording based on the key-press method. However, the analysis of discrete variables (i.e., present or absent responses) registered by key-press could be insufficient to capture dynamic aspects of inhibitory control. Trying to overcome this limitation, in the present study we used a mouse tracking procedure to characterize movement profiles related to proactive and reactive inhibition. A total of fifty-three participants performed a cued GNG and an SST. The cued GNG mainly involves proactive control whereas the reactive component is mainly engaged in the SST. We evaluated the velocity profile from mouse trajectories both for responses obtained in the Go conditions and for inhibitory failures. Movements were classified as one-shot when no corrections were observed. Multi-peaked velocity profiles were classified as non-one-shot. A higher proportion of one-shot movements was found in the SST compared to the cued GNG when subjects failed to inhibit responses. This result suggests that proactive control may be responsible for unsmooth profiles in inhibition failures, supporting a differentiation between these tasks.

May I have your attention, please? Methodological and Analytical Flexibility in the Addiction Stroop

Theoretical models of addiction predict that an attentional bias towards drug/alcohol related cues plays a key role in development and maintenance of addictive behaviours. However, data from the empirical research testing these predictions is equivocal. This ambiguity may in part be a consequence of substantial variability in the methods used to operationalise attentional bias. The aim of this research was to examine the variability in key design and analysis decisions of the addiction Stroop. Using a pre-registered design, we systematically searched the literature and identified 46 studies describing an alcohol Stroop task and 25 studies describing a smoking Stroop task. We extracted information about the design of the Stroop task, including but not limited to; administration (paper-and-pencil vs. computerised), response (key press vs. voice), number of drug-related stimuli used, number of stimulus repetitions, design (block vs. mixed). For analysis decisions we extracted information on upper- and lower-bound reaction time cut-offs, removal of individual reaction times based on standard error cut-offs, removal of participants based on overall performance, type of outcome used, and removal of errors. Based on variability from previous research there are at least 1,451,520 different possible designs of the computerised alcohol Stroop and 77,760 designs of the computerised smoking Stroop. Many key design decisions were unreported. Similarly, variability in analyses decisions would allow for 9,000 different methods for analysing the alcohol Stroop and 5,376 for the smoking Stroop. This flexibility in the design and analysis of a widely used measure of attentional bias may contribute to equivocal findings, unreliable tasks and inability to replicate research. Future research should work towards a gold standard addiction Stroop with reliable psychometric properties. This will allow us to confidently test predictions and lead to progress within the field.

Contextual within-trial adaption of cognitive control: Evidence from the combination of conflict tasks

It is assumed that we recruit cognitive control (i.e., attentional adjustment and/or inhibition) to resolve two conflicts at a time, such as driving towards a red traffic light and taking care of a near-by ambulance car. A few studies have addressed this issue by combining a Simon task (which required responding with left or right key-press to a stimulus presented on the left or right side of the screen) with either a Stroop task (which required identifying the color of color words) or a Flanker task (which required identifying the target character among flankers). In most studies, the results revealed no interaction between the conflict tasks. However, these studies include a small stimulus set, and participants might have learned the stimulus-response mappings for each stimulus. Thus, it is possible that participants have more relied on episodic memory than on cognitive control to perform the task. In five experiments, we combined the three tasks pairwise, and we increased the stimulus set size to circumvent episodic memory contributions. The results revealed an interaction between the conflict tasks: Irrespective of task combination, the congruency effect of one task was smaller when the stimulus was incongruent for the other task. This suggests that when two conflicts are presented concurrently, the control processes induced by one conflict source can affect the control processes induced by the other conflict source.

How do we segment text? Two-stage chunking operation in reading

Chunking in language comprehension is a process that segments continuous linguistic input into smaller chunks that are in reader’s mental lexicon. Effective chunking during reading facilitates disambiguation and enhances efficiency for comprehension. However, the mechanisms of chunking remain elusive, especially in reading given that information arrives simultaneously yet the written systems may not have explicit cues for labeling boundaries such as Chinese. What are the mechanisms of chunking operation that mediates the reading of the text that normally contains hierarchical information? We investigated this question by manipulating the lexical status of the chunks at distinct levels of grain-size in four-character Chinese strings, including the two-character local chunk and four-character global chunk. Participants were asked to make lexical decision on these strings in a behavioral experiment, followed by a passive reading task when their electroencephalography (EEG) were recorded. The behavioral results showed that the lexical decision time of lexicalized two-character local chunks was influenced by the lexical status of four-character global chunk, but not vice versa, which indicated that the processing of global chunks possessed priority over the local chunks. The EEG results revealed that familiar lexical chunks were detected simultaneously at both levels and further processed in a different temporal order -- the onset of lexical access for the global chunks was earlier than that of local chunks. These consistent behavioral and EEG results suggest that chunking in reading occurs at multiple levels via a two-stage operation -- simultaneous detection and global-first recognition.Significance StatementThe learners of a new language often read word by word. But why can proficient readers read multiple words at a time? The current study investigates how we efficiently segment a complicate text into smaller pieces and how we process these pieces. Participants read Chinese strings with different structures while their key-press responses and brain EEG signals were recorded. We found that texts were quickly (about 100 ms from their occurrences) segmented to varied sizes of pieces, and larger pieces were then processed earlier than small pieces. Our results suggest that readers can use existing knowledge to efficiently segment and process written information.

The impact of eye contact on the sense of agency

Recent research suggests that eye contact can lead to enhanced self-awareness. A related phenomenon, the sense of agency deals with the notion of the self as the origin of our actions. Possible links between eye contact and agency have been so far neglected. Here, we investigated whether an implicit sense of agency could be modulated by eye gaze. We asked participants to respond (button press) to a face stimulus: looking or not at the participant (experiment 1); or displaying distinct eye gaze before or after a mask (experiment 2). After each trial, participants estimated the time between their key press and the ensuing effects. We found enhanced intentional binding for conditions that involved direct compared to averted gaze. This study supports the idea that eye contact is an important cue that affects complex cognitive processes and suggests that modulating self-processing can impact the sense of agency.
