Modeling of variables related to problematic social media usage: Social desirability tendency example

Social media usage has been popular for the last decade. Individuals use their social media environments for various reasons such as to socialize, play games, have fun and share posts. Overuse of these environments may lead to negative psychological and behavioral consequences for individuals. Additionally, it increases the worries about potential addicted/problematic use of social media. In this study, it is aimed to determine the level of problematic social media usage of participants who are active social media users and to analyze the relationships between problematic social media usage and various personal characteristics and social variables. Study in relational screening model is carried out with the participation of 580 volunteers. Partial least squares (PLS) structural equation modeling is used to analyze the data obtained through various scale according to the research model. The structural equation modeling analysis shows that there is a significant relationship between problematic social media usage and the daily time of social media usage, the use of frequency of social media for recognition, publicity, communication/interaction and education, loneliness, and social anxiety. The variable which shows higher correlation between problematic social media usage is social anxiety.     

An experimental examination of the effects of alcohol consumption and exposure to misleading postevent information on remembering a hypothetical rape scenario

We experimentally examined the effects of alcohol consumption and exposure to misleading postevent information on memory for a hypothetical interactive rape scenario. We used a 2 beverage (alcohol vs. tonic water) × 2 expectancy (told alcohol vs. told tonic) factorial design. Participants (N = 80) were randomly assigned to conditions. They consumed alcohol (mean blood alcohol content = 0.06%) or tonic water before engaging in the scenario. Alcohol expectancy was controlled by telling participants they were consuming alcohol or tonic water alone, irrespective of the actual beverage they were consuming. Approximately a week later, participants were exposed to a misleading postevent narrative and then recalled the scenario and took a recognition test. Participants who were told that they had consumed alcohol rather than tonic reported fewer correct details, but they were no more likely to report incorrect or misleading information. The confidence–accuracy relationship for control and misled items was similar across groups, and there was some evidence that metacognitive discrimination was better for participants who were told that they had consumed alcohol compared with those told they had tonic water. Implications for interviewing rape victims are discussed.     

Revelation effect in metamemory

Test items are more likely to be judged as previously studied if they need to be discovered before the recognition decision. In the present experiments, this revelation effect was extended to metamemory judgments. Participants studied word pairs and then tried to recall the second word of each pair when given the first word as a cue. In Experiment 1, a fragment of the target was either gradually increased in size or held constant, and in Experiment 2, sometimes an anagram of the cue was given instead of the cue itself. Thus, for some items, there was a revelation task before a recall attempt. If recall failed, the participants gave feeling-of-knowing (FOK) ratings. In both experiments, the participants gave higher FOK ratings after a revelation task, even though the items that these FOKs referred to remained unrecalled. Analyses showed a criterion shift but no differences in sensitivity.     

Perception of homosexuality among Turkish university students: the roles of labels, gender, and prior contact

The author examined three questions: (a) What constitutes participants' causal attributions for the labels "gay," "lesbian," and "homosexual"?; (b) Do participants' attitudes vary by labels?; and (c) Do participants' attitudes vary with previous social contact with homosexuals? Participants were 334 university students (140 women, 194 men). Three labels--"gay," "lesbian," and "homosexual"--served as probes. The author investigated participants' attributions toward causes of homosexuality with Principal-Component Analysis (PCA) and obtained 4 components: disorder, problems, modeling or sensation seeking, and preference. The author found the most negative attitudes toward the label "gay." Finally, participants who had previous contact with homosexual people held more positive attitudes toward homosexuality than did the others. The author also obtained some gender differences. The author discussed the results in the light of the current literature.     

Millennials' changing mobility preferences: A telecommuting case in Istanbul

Daily mobility behaviors, especially in cities with high traffic density, are among the most fundamental drivers of quality of life. Obligatory commuting necessitates individuals sacrificing their time, money, and geographic freedom to ensure their mobility. The personal cost of fatigue, stress, and environmental cost of carbon emissions is likewise substantial. The COVID-19 pandemic led to a widespread shift to telecommuting. The pandemic has permitted an unprecedented opportunity to study Millennials' attitudes towards commuting and telecommuting. A semi-structured interview method was used with Millennial (now the largest percentage of the workforce) white-collar (disproportionately able to do their work remotely) workers living in the megacity of Istanbul to understand how telecommuting has altered consumer commuting habits, values, preferences, and well-being. The results of this study show that Millennial white-collar workers in Istanbul see compulsory commuting as a waste of time, a stress factor, and an unwanted task. The shift towards telecommuting lowered the Millennials' tolerance for traffic and long commutes and reveals willingness for immobility at peak hours and appreciation of spatial independence as a lifestyle that increases quality of life. The need for understanding transport decisions has never been more pressing with the growth of megacities and the climate change crisis. This research has important implications for white-collar employees and their employers, as well as academics and public policy makers, who seek to understand mobility preferences and lifestyles of different generations and the environmental implications in a dynamic environment.     

Name or hum that tune: Feeling of knowing for music

This is the first reported research that explores the feeling of knowing (FOK) for musical stimuli. Subjects attempted to recall melodies and titles of musical pieces, made FOK ratings when recall failed, and then had a recognition test. With instrumental music (Experiment 1), more titles were recalled when melodies were given as cues than vice versa. With songs whose lyrics were not presented (Experiment 2), however, more melodies were recalled than were titles. For nonrecalled items, although the overall levels of recognition did not differ, FOK ratings were higher for titles than for melodies in Experiment 1, and the opposite pattern occurred in Experiment 2. In both experiments, the FOK ratings predicted melody recognition more accurately than they did title recognition.     

Protean and boundaryless career attitudes and organizational commitment: The effects of perceived supervisor support

Despite the traditional sentiment that protean and boundaryless career attitudes indicate a decline in organizational commitment, little empirical evidence is available. The present study examined the relation of protean and boundaryless career attitudes to organizational commitment and whether the perceived supervisor support moderated these relationships. The results based on data from 380 employees demonstrate that organizational mobility preference is negatively related to all three dimensions of organizational commitment. Self-directed career management is positively related to affective and normative commitment and negatively related to continuance commitment, while values-driven career orientation is negatively related to normative commitment. Moreover, there is no significant evidence provided for a moderating effect of perceived supervisor support on the relationships between protean and boundaryless career attitudes and organizational commitment. Perceived supervisor support has only a main effect on affective and normative commitment.     

A new driver behavior model to create realistic urban traffic environment

This paper presents a new driver behavior model, which emulates various driving styles (i.e. behaviors) for different categories of drivers. The model was highly parametric and was developed based on a two-layer Hierarchical Concurrent State Machines (HCSM) programming framework. Our study has been specifically oriented to create a realistic urban traffic environment with hazardous situations typical of real life in a driving simulator, and let the novice drivers to practice in a safe environment. In our study, we used TRAFIKENT driving simulator as a test-bed. Experiments and evaluations demonstrated satisfactory results in terms of behavioral validity of our model.
