A growing body of research has compared the effects of explicit and implicit corrective feedback (CF) on L2 accuracy. However, L2 performance is not limited to accuracy. Fluency is another important aspect of L2 performance, but less is understood about its relationship with CF and CF explicitness/implicitness. This experimental study examined the effects of explicit correction versus implicit recasts on not only the accuracy but also the fluency of L2 speech during videoconferencing. Forty-eight lower-intermediate learners of English as a foreign language (EFL) were assigned to an explicit correction group, an implicit recast group, and a no-feedback group. Each engaged in eight picture description tasks with the researcher and received feedback according to the group they came from. Pre and posttests (immediate and delayed) of accuracy and fluency were conducted using additional picture tasks. Accuracy was measured by calculating the percentage of learners’ (a) error-free clauses and (b) error-free T-units. Fluency was measured by calculating the number of (a) syllables per minute and (b) meaningful syllables per minute. Statistical analyses included (a) two-way repeated measures ANOVAs with feedback type as the between-subject factor and time as the within subject factor, (b) Planned comparisons, which treated the two experimental groups as one group and compared their mean with the mean of the control group, (c) Bonferroni post hoc tests, which examined the pairwise differences, and where needed, (d) paired sample t-tests, which examined each group’s pretest-posttest differences. As for accuracy, planned comparisons showed that videoconferencing CF, irrespective of its explicitness/implicitness, improved accuracy. Further analyses showed that whereas the explicit correction group outperformed the control group on both the immediate and delayed posttests, the recast group did not. However, the explicit feedback group produced a significantly less fluent speech compared to the recast group and the control group. But this was true on the immediate posttest and not on the delayed posttest. Pretest-posttest comparisons further indicated a negative effect for explicit correction but a positive effect for recasts on L2 fluency. The results suggest that (a) while explicit correction assisted accuracy, it negatively influenced fluency, and (b) while implicit correction seemed to assist fluency, it was not as effective as the effect of explicit correction on L2 accuracy. Further analyses indicated that the explicit correction group exhibited a large amount of monitoring behaviour on the immediate posttest, whereas the other two groups did not. The results are explained using an information-processing perspective of language performance and a knowledge proceduralization model of language development. The theoretical, empirical, and pedagogical implications are also discussed. / Graduate

This thesis aims to contribute to the field of interaction design by exploring the use of nonverbal cues in FTF communication with the aim of generating knowledge that can be used as an alternative approach for assessing and designing text-based CMC media. To achieve this goal, movement in is analysed in the nonverbal and collaborative dimensions of FTF communication. This presents the possibility to assess text-based CMC media based on a better understanding of the use of nonverbal cues and FTF communication as a standard. The assessment and design based on this concept is tested in the design phase. This process provides a platform for discussion and evaluation of an alternative approach for designing text-based CMC media with a focus on interaction between communicators.

This research examines escalation of commitment in capital investment decisions and the extent to which it can be mitigated using a cognitive prime. Specifically, I examine the use of a cognitive prime as a way to mitigate escalation in three decision-making settings: (1) individual, (2) face-to-face team, and (3) computer-mediated team. Continued investment in failing projects is costly for firms. The use of a cognitive prime to reduce escalation would provide a low cost way to mitigate escalation. In this study, participants are primed to think about sunk costs. The expectation is that priming individuals to think about sunk costs will increase the accessibility of sunk cost knowledge and reduce the likelihood of continued investment in the failing project. Further, based on Persuasive Arguments Theory, it is expected that the prime will reduce escalation in teams communicating in a computer-mediated setting more than in any other decision setting. The results of the experiment support the prediction that priming will reduce escalation and did so in all decision making settings. Further, the results indicate that, in the computer-mediated setting, primed teams had the least amount of escalation behavior coupled with the largest difference in escalation compared to teams that were not primed.

Adolescents are adopting computer-mediated communication (CMC) at a higher rate than any other age group, with CMC becoming integral to their social relationships. This is particularly significant given the role peer relationships play in adolescent mental health. The purpose of this quantitative, quasi-experimental study was to explore the relationship between adolescent CMC and social anxiety. The research was guided by Erikson's theory of psychosocial development and Kock's media naturalness theory. This multiwave panel study included a convenience sample of 58 adolescents ages 11 to 18. Surveys were completed on participant's social skills and introversion, and daily data were gathered on CMC, face-to-face communication, and social anxiety. Three regression models were produced from each day's data. Results indicated a modest relationship between daily CMC and social anxiety. Results also indicated CMC users with lower social skills or higher in introversion may be at greater risk for social anxiety. Lower face-to-face communication was also found to be related to increased social anxiety in CMC users. Findings may be useful to researchers seeking to identify specific populations who are at greater risk for negative outcomes in CMC use. Findings may also be useful to clinicians, educators, and parents interested in CMC's role in adolescent mental health or its impact on the quality of adolescent peer relationships.

Research suggests that Internet and cell phone overuse may result in lower levels of social skills and encourage isolation from peers. Less clear is whether the duration of computer-mediated communication (CMC) influences adolescent perception of their social skills competency or emotional health. This research was guided by the social cognitive theory, which suggests that social self-efficacy (SSE), the belief that they have the skills to engage successfully with others in conversation and social activities, develops from mastery experiences that regulate thought, motivation, and action. This quantitative cross-sectional survey design utilized a convenience sample of 49 adolescents ages 11-19, living in Austin County, TX, to examine the impact of CMC duration on adolescent SSE, social anxiety, and depression. Regression analyses indicated CMC duration did not significantly affect SSE, social anxiety, or depression at the p <. 05 level. Computer-mediated communication duration did influence SSE at the p = .07 level, suggesting a trend toward statistical significance. Post hoc analysis revealed a significant interaction at the p < .05 level when CMC restriction severity was tested as a moderator in the CMC duration-SSE relationship. These findings suggest that the interaction between CMC duration and restrictions may influence social self-efficacy. Additional research on the relationship between CMC and adolescent psychosocial health would be helpful, particularly using larger and more generalizable samples. This study may inform the efforts of authority figures to adolescents, specifically, on the ways in which technological changes affect adolescent social development and will help to ensure that adolescents are safe, psychologically healthy, and able to maintain healthy relationships.

Understanding normative developmental patterns in romantic relationships within cultural-historical contexts is a vital research agenda, and contemporary relationships develop amid pervasive socio-technological advancements. The role of technology in relationship functioning is relevant as romantic relationships are among the most important types of relationships and technology may substitute proximity, a core imperative of the attachment system. This study described patterns of computer-mediated communication (CMC) in young adult romantic relationships. Specifically, we hypothesized that core relational and personality constructs were linked to participants’ interpretations and reactions to CMC. Participants were 97 college students who provided global scores for rejection sensitivity, attachment representations, relationship satisfaction, and data about CMC with their romantic partner. Participants were prompted twice daily for two weeks to respond to questions assessing the nature and reaction to their most recent CMC with their romantic partner. Participants used texting more than any other CMC and communicated with romantic partners more than all others combined. Participants’ high relationship and communication satisfaction remained relatively constant. The 97 participants completed 1,616 mobile responses. Reported response latency was higher for men than women. Significant negative correlations emerged between interaction ratings, rejection sensitivity, and both insecure attachment dimensions. Regression analyses revealed only main effects for response latency and insecure attachment in predicting interaction ratings for women. No significant interactions emerged between response latency and attachment/response latency. For men, insecure attachment representations and rejection sensitivity demonstrated direct effects on interaction ratings. Avoidant attachment and response latency demonstrated a statistically significant interaction. Response latency and the interaction rating were negatively related only for men who scored low in avoidance. This study contributes to the body of literature assessing outcomes and qualities of romantic relationships in emerging adulthood. Technological communication is a key feature of young couples’ communication and appears more prevalent in romantic relationships than other relationships. Additionally, core relational and personality characteristics are substantially correlated to interpretations of momentto- moment interactions via technology.

College students are using their mobile devices during class and this research investigates different aspects of why college students feel so inclined to use these devices during class as well as by what means are students using to participate in computer-mediated communication while simultaneously engaging in classes. This research surveyed 146 students on their perceived use of their own mobile device use during class. The study compared how often different types of devices, such as mobile phones, tablets, and laptops, and different types of social media outlets, like Facebook, Twitter, and other social media websites, were used during class. The study compares these devices and media outlets to students’ perception of the levels of incivility of using these various means of communication during class and their perceptions of how they impact their ability to focus on the class. Mobile phones, Facebook, and Twitter use were negatively associated with the perception of the incivility of use in the classroom. This research found phone use was viewed as more uncivil than tablets and tablet use was viewed as more uncivil than laptop use. In addition, students’ perceptions of instructors’ tolerance of mobile phone and laptop use was negatively associated with their perception of the incivility of using those devices during class. All three tested mobile devices and all three tested social media outlets were positively associated with students’ perception that its use affects their ability to focus on the class. This research found mobile phones use as more distracting than laptops and laptops use as more distracting than tablets.

This study aimed to explore the ways in which Hebrew is currently being manipulated online through a linguistic deviation called Fakatsa. In this study, participants were asked to rate random statements of frivolous or serious topics in either standard grammatical Hebrew or Fakatsa Hebrew conditions on specific judgment values. It was hypothesized that participants would rate the Fakatsa writer negatively on certain characteristics, such as intelligence, education, religiosity, and nationalism and positively on other characteristics, such as femininity and creativity. Twenty-four participants completed this experiment. Results showed that participants responded as expected for certain negative attributes typical of Fakatsa and deviations to computer-mediated communication and did not respond as expected for any the positive attributes typical of Fakatsa. The results showed that fluent Hebrew speakers viewed users of the Fakatsa manipulation differently than users of standard Hebrew and may suggest personal biases and perceptions when encountering computer-mediated communication.
