Comparing Dichotomous And Polytomous Items Using Item Response Trees, Daniel Jenkins
Comparing Dichotomous And Polytomous Items Using Item Response Trees, Daniel Jenkins
Browse all Theses and Dissertations
Research on the optimal number of response options on graphic rating scales has yielded mixed results such as that more scale points are better; there is an optimal range; or that it does not matter. The present study compared the psychometric properties of dichotomous and polytomous personality items using several methods of scoring including summed scores, item response theory (IRT), and item response trees. It was found that regression models based on dichotomous items explained similar amounts of variance in careless responding as models based on polytomous items. In addition, scores from dichotomous models were more closely related to the …

Examining The Role Of Trust In Peer-Assisted Learning, Peter Crowe
Browse all Theses and Dissertations
Team and peer-assisted learning methodologies are becoming increasingly prevalent in both academia and industry. Learning with others is used with the assumption that individuals learn better in groups. The studies in this paper examine aspects of Peer-Assisted Learning in order to understand whether the claims of improved individual learning are substantiated, and if so, how that improved learning occurs. The cognitive mechanism examined in the studies below is the development of trust between peers on a learning task. Participants were selected from Wright State University and were predominantly undergraduate Psychology 101 students. Results indicated that Peer-Assisted Learning conditions did not …
Extraversion And Emotional Expressiveness: Moderators Of The Relationship Between Curmudgeon Personality And The Quality Of Social Relationships, Md Rashedul Islam
Extraversion And Emotional Expressiveness: Moderators Of The Relationship Between Curmudgeon Personality And The Quality Of Social Relationships, Md Rashedul Islam
Browse all Theses and Dissertations
Curmudgeon personality, the extent to which a person dislikes most things, has recently received increased attention from researchers. Existing research has focused on either the relationships between curmudgeon personality and Big Five personality factors (e.g., extraversion, agreeableness) or curmudgeon personality and various workplace outcomes (e.g., job satisfaction, organizational commitment, and turnover intention). The current research examined whether curmudgeon personality and other personality traits (i.e., extraversion and emotional expressiveness) interact with each other to influence the quality of individuals’ social relationships at work. Analyses using an MTurk dataset (N = 529) showed some evidence of these interaction effects though some directions …
Attitude Strength And Situational Strength As Moderators Of The Job Satisfaction – Job Performance Relationship, Joseph William Dagosta
Attitude Strength And Situational Strength As Moderators Of The Job Satisfaction – Job Performance Relationship, Joseph William Dagosta
Browse all Theses and Dissertations
Workers who are satisfied with their jobs are better performers, but prior research has found a plethora of moderating variables between job satisfaction and job performance (Ostroff, 1992, Schleicher, Watt, & Greguras, 2004; Spector, 1997). Prior research has suggested that job attitude strength can strengthen the relationship between job satisfaction and job performance and that the relationships between personality variables and extra-role job performance are stronger in weak rather than strong workplace situations (Meyer et al., 2014; Shleicher et al., 2015). In the current study, I investigated the interaction between job satisfaction, job attitude strength, and situational strength on job …
Discriminating Targets Among Distractors In A Virtual Shopping Environment With Different Rack Orientations: Testing A Model Of Visibility, Tyler Sinclair Whitlock
Discriminating Targets Among Distractors In A Virtual Shopping Environment With Different Rack Orientations: Testing A Model Of Visibility, Tyler Sinclair Whitlock
Browse all Theses and Dissertations
Objective: This study measured observers’ abilities to identify letter targets distributed among number distractors in a virtual shopping environment. Head-turning behavior was also continuously recorded throughout each trial. The data were then used to test whether a model’s prediction for the duration of visibility needed for target detection in a virtual shopping environment (Parikh & Mowrey, 2014) generalize to the more realistic shopping task of identifying a target on a shelf. Currently, the model predicts the visibility of the locations of targets in traditional racks oriented 90° to the aisle (perpendicular) as well as racks oriented at 30°, 45, 135°, …

Induction And Transferral Of Flow In The Game Tetris, Kevin John O'Neill
Browse all Theses and Dissertations
We looked at the facilitation and transfer of a flow state in a cognitive context. Subjects played a manipulated version of the game Tetris, and we gathered data on their gameplay performance on pre- and post-tasks, as well as a set of questionnaires which measure flow and perceived task effort. The altered version of Tetris includes an artificial intelligence agent that continually assesses the participant’s skill and adapts the challenge level of the game to match the participant’s skill. An adaptive condition characterized by challenge-skill balance was hypothesized to induce flow, reduce perception of effort, and improve performance. We found …

Trust Discounting In The Multi-Arm Trust Game, Michael Collins
Browse all Theses and Dissertations
Social interactions are complex and constantly changing decision making environments. Prior research (Mayer, Davis, & Schoorman, 1995) has found that people use their trust in others as a criterion for decision making during social interactions. Trust is not only relevant for human-human interaction, but has also been found to be important for human-machine interaction as well, which is becoming a growing feature in many work domains (De Visser et al., 2016). Prior research on trust has attempted to identify the behavioral characteristics an individual (trustor) uses to assess the trustworthiness of another (trustee) to determine the trustor's level of trust. …

Browse all Theses and Dissertations
Collaboration, cohesion, and trust within teams can lead to beneficial outcomes such as innovation, speed of innovation delivery, enhanced creativity, and improved performance. Because of the prevalence of teams in the workforce, it is important that teams function at their highest capacity. One way to enhance team functioning may be to improve emotional intelligence (EI) in team members. Research has shown that higher EI is related to individual benefits such as stress resilience, better communication, relationship satisfaction, and improved performance. Team benefits of higher EI include greater cohesion, cooperation, trust, and performance. This study examined whether an emotional competency training …

Learned Helplessness In Industrial-Organizational Psychology: Relationships With Locus Of Control, Self-Efficacy, And Feedback-Seeking Behavior, Nicholas Kovacs
Browse all Theses and Dissertations
Researchers have suggested that self-efficacy and feedback-seeking behavior (FSB) are effective in enhancing performance. To improve performance in the workplace, research should focus on how psychologists can enhance these constructs in employees. Though locus of control (LOC) relates to self-efficacy and increased FSB, research has revealed issues in LOC (e.g., failure to predict performance, range restriction, failure to predict behaviors). The current study examined the effects of perceived “lack of control”, learned helplessness, over LOC on both self-efficacy and FSB in two different samples: a student sample (N = 321) and a work sample (N = 794). Learned helplessness accounted …

When receiving assistance from an automated aid, human operators do not necessarily perform better than without the automated aid. The current work explored the impact of integrating the automated aid with the task information in low prevalence conditions. Specifically, this work compares displays where the automated aid was integrated with task information in general or with more meaningful task information. Subjects performed a speeded judgment task with the assistance of an automated aid, varying in display type, difficulty, and prevalence. Results indicated that there was no effect of display type or prevalence on human temporal performance, and that the effect …

This research expands upon the research conducted by Clark and Wilkes-Gibbs (1986) on how individuals collaborate and reach common ground in the domain of objects into the domain of action. Pairs of participants (N = 22) were asked to complete a set of six maneuvers with a remote-control car. Dialogue was transcribed and analyzed for total word count, verb phrase count, number of turns taken, number of errors committed, and selected other linguistic characteristics. Total word count, verb phrase count, number of turns taken, and number of errors committed all significantly decreased over time, either linearly or logarithmically. This research …

Antecedents Of Voice: The Moderating Role Of Proactive Personality, Alice Pyclik
Browse all Theses and Dissertations
When employees are dissatisfied, they can choose a destructive solution such as quitting, or they can use voice to effect organizational change. A sample of 277 full-time employees in the United States responded to an online survey of voice, ethical leadership, core self-evaluation, proactive personality, affective commitment, and several control variables. Results from simple, multiple, and hierarchical regression analyses indicated that ethical leadership, core self-evaluation, and proactive personality have positive relationships with voice. In addition, ethical leadership facilitates voice through the path of affective commitment. Proactive personality compensates for low levels of affective commitment. Thus, managers can increase voice among …

Star employees have significant influences on the successes or failures of organizations. Current research on stars has not addressed who a star is or how stars are different from other good employees. In this study I tested the efficacy of a proposed definition of star employees and verified the accuracy of other previously established characteristics and behaviors associated with stars. In addition, I qualitatively explored managers’ perceptions of star employees. The study consisted of two separate samples: managers identified on MTurk (n = 40) and high-level executives from various industries (n = 46). Participants provided a series of open responses …

Impact Of Spatial Variability And Masker Fringe On The Detectability Of A Brief Signal, Michelle H. Wang
Browse all Theses and Dissertations
The effect of masker spatial variability and masker fringe on the perception of a brief tone in noise was investigated in a detection task. Simpson (2011) found large effects of spatial variability (randomizing masker locations from trial to trial) in a masked localization experiment, as well as two effects of masker fringe (masking noise before the onset of the target): 1) cuing the masker location (spatial cuing effect) and 2) temporally separating the onset of the masker and the onset of the target (onset effect). In contrast, in detection studies, the effects of masker spatial variability are small (e.g., Bernstein …

Using Eeg To Examine The Top Down Effects On Visual Object Processing, Joseph D. Borders
Browse all Theses and Dissertations
Object recognition entails a complex interplay between top-down and bottom-up signals. Yet, limited research has investigated the mechanisms through which top-down processes, such as task context and behavioral goals impact the neural basis of visual object processing. Using electroencephalography (EEG), we studied the temporal dynamics of task and object processing to identify how early the impact of task can be observed. We recorded ERPs from participants as they viewed object images from four categories spanning animacy (Inanimate: roller-skate, motorbike; Animate: cow, butterfly) and size (Large: motorbike, cow; Small: roller-skate, butterfly) dimensions under four task conditions comprising conceptual (naturalness, size) and …

Intelligent agent technologies are increasing the potential capacity for systems to behave more autonomously and are enabling more advanced human-autonomy teaming. For instance, future applications of human-autonomy teaming for the command and control of unmanned vehicles are now under consideration. This would involve a shift from a supervisory control approach to a teaming structure. These two approaches, instantiated as the task division and relationship between a human operator and a teammate, were empirically examined. The team’s composition, either human-human or human-autonomy, was also considered. A control station that supports single operator management of multiple simulated unmanned vehicles performing a base …

Browse all Theses and Dissertations
Careless responding (CR) can negatively affect the quality of self-report data and thus the resulting conclusions researchers draw from the data. The purpose of the current study was to investigate whether interactive warnings, which alert careless respondents in real time, reduce CR more than traditional, non-interactive warnings. I used a 4 x 4 mixed factorial design to examine these relationships. The between group factor was the type of warning used, which consisted of four levels (i.e., a control, no warning group, a traditional, non-interactive warning, an interactive threatening warning message, and an interactive encouraging message), and the within person factor …

Personality has been extensively researched but the literature has not lived up to its potential for application. Personality variables such as self-control can identify qualified applicants, while minimizing adverse impact. I designed two SJT measure of self-control. The first SJT was hypothesized to predict college grade point average. The second SJT was hypothesized to predict counterproductive work behavior. I administered the first SJT to 676 undergraduates. I administered the second SJT to 608 employed people. Most hypotheses were fully supported. Both SJTs had incremental validity over and above self-report personality measures. The results demonstrate the potential of SJTs to measure …

Prevalence Visual Search: Optimal Performance And The Description-Experience Gap, Hanshu Zhang
Browse all Theses and Dissertations
Real-world visual search differs significantly from the laboratory task. One distinct feature is that most targets in real-world visual search are low prevalence. Considering the important practical connections between the laboratory study and applied research, there has been a resurgence in exploring prevalence effects on visual search performance, especially the effect that targets are more likely to be missed when they have low prevalence. Though there is a consensus that target misses are due to a liberal criterion, previous studies failed to consider the potentiality of optimal performance from the perspective of Signal Detection Theory, which also predicts a the …

The traditional method of maintaining spatial awareness through visual displays can cause visual system overload and lead to performance decrements. This study examined the benefits of spatialized auditory, tactile, and audio-tactile cues for maintaining awareness as a method of enhancing visual search performance. I examined visual search performance in an immersive, dynamic, three-dimensional (360-degree), virtual reality environment with no cues, spatialized auditory cues, degraded spatialized auditory cues, spatialized tactile cues, spatialized audio-tactile cues, and degraded spatialized auditory with tactile cues. Results indicated a significant reduction in visual search time from the no-cue condition when any cues were presented. The tactile …

This dissertation considers what it means to think differently, using naturalistic verbal evidence. This problem is inspired by a gap within the Wisdom of the Crowd (WoC) literature, but relevant to the study of language processes, mental models, and the vast emerging resource of social media data. I propose a methodological framework to characterize diversity of thought through the quantification of social media data. Four stages of research considered: a) the properties of a sample domain, b) how to identify and select diagnostic content using classification methods, c) how to quantify qualitative content in order to categorize and compare individuals, …

The progression of technology and adaptive automation has shown tremendous promise in reducing both physical and mental task demands, while allowing the maintenance or improvement of overall performance. Consequently, a user is able to maintain task performance with relatively more ease and reallocate spare time and energy to additional tasks. Quantifying the resources that one has left is an ongoing, relatively open, research objective for human factors psychologists. Here, we created a standardized, individual-level metric to serve as an estimate of multi-tasking efficiency. We go beyond just rank-order, or categorical labels of suffering from, benefiting from, or adequately maintaining performance …

Spatial memory for the layout of large-scale environments, configural spatial memory, has typically been construed as being very structured, using something like a metric coordinate system and using environmental objects to define that coordinate system. Inside of buildings, rectangular rooms have walls at right angles that have been considered to fulfill this role. However, the influence of non-spatial factors and considerations of relatively unstructured environments have not received much attention. Semantic organization was found to improve configural spatial memory for landmark objects in rooms with walls and it was independent of the structural relations among landmark objects (Colle & Reid, …

The purpose of the present research was to examine the influence of meditation experience on biopsychosocial responses to stress, empathy, and sense of self. An expanded sense of self was examined as a pathway through which meditation experience influences appraisals, affect, and empathy. It was expected that meditation experience would predict greater challenge stressor appraisals in response to an acute psychosocial stressor and associated affective, behavioral, and psychophysiological stress outcomes. In addition, it was expected that greater meditation experience would predict higher trait empathy and empathic accuracy. Participants (N = 110) included experienced meditators from a variety of practices and …

The Biobehavioral Model Of Persuasion: The Role Of Cognitive Processing In Challenge And Threat Message Framing, August Capiola
Browse all Theses and Dissertations
Persuasive messages are meant to influence people towards endorsing attitudes, intentions, and behaviors suggested in the message. However, describing the kinds of messages that are persuasive is not as helpful as understanding why certain messages are persuasive, yet others are not. The biobehavioral model of persuasion suggests that challenge-framed messages (messages that evoke low/moderate concern and high efficacy) are persuasive because they facilitate greater message elaboration leading to outcomes aligned with message suggestions. The following paragraphs outline the BMP and describe two experiments that tested the postulate that challenge-framed messages evoke greater message elaboration. In the first experiment (N = …

Too Long And Too Boring: The Effects Of Survey Length And Interest On Careless Responding, Cheyna Katherine Brower
Browse all Theses and Dissertations
Careless responding (CR), also called insufficient effort responding (IER), occurs when survey participants respond to items without regard to item content. The presence of careless responding threatens the validity of inferences made from self-report data (Huang et al., 2012; Huang et al., 2015). This study examines the effects of two proposed causes of careless responding (Mead & Craig, 2012): questionnaire length and participant disinterest. Specifically, I hypothesized that (a) questionnaire length is positively related to careless responding, (b) participant interest is negatively related to careless responding, and (c) questionnaire length has a weaker relationship with careless responding among participants who …

This work describes an Ecological Interface Design (EID) comparison of five displays (Alphanumeric, 2D and 3D Aggregate, Radial, and Treemap) on accuracy and latency performance for simple cyber network data analysis tasks. Twenty students from the Computer Science and Engineering Department at Wright State University participated for compensation. Questions (n = 12) ranged from global to specific aspects of the data and required two types of responses: numerical estimates and binary visual judgments. EID principles of attunement and specificity (Bennett & Flach, 2011) guided the interpretation of results. Participants answered faster when the display's visual forms (vertical extent, area, or …

Social media data promise to inform the disaster response community, but effective mining remains elusive. To assist in the analysis of community reports on disaster from social media, I draw on an integrated model of psycholinguistic theory to investigate the patterns by which language use changes as a function of environmental influence. Using social media corpora from several disasters and non-disasters, I examine variations in patterns of lexical choice between domain independent paired antonyms with respect to an Internet-specific base rate to determine generic sentinels of breach of canonicity. I examine social media content with respect to disaster proximity and …

Browse all Theses and Dissertations
Human-human communication is a coordinated dance (Clark, 1996) that requires each participant to consider the other participants. The majority of this coordination centers on the conversational grounding process that develops and maintains the common ground, or shared understanding between the individuals (Clark and Schaefer, 1989). Conversational grounding is also a crucial process for human-computer interaction using language-based methods, such as spoken dialogue systems. Previous work has tied grounding processes to the performance outcomes in collaborative tasks (Reitter and Moore, 2014; Gergle et al., 2013, 2004; Clark and Krych, 2004), making it a high priority for increasing capabilities of spoken dialogue …

The validity of individual responses is required for valid inferences drawn from data. Insufficient Effort Responding (IER; Huang, Curran, Keeney, Poposki, & DeShon, 2012) is one possible threat to individual response validity. There are many methods to detect IER, but the Psychometric Synonyms Index, despite its practical utility, is understudied. The purpose of this study is to provide recommendations for its use that are empirically grounded. Using a simulation, I found that the strength of the within-pair correlations used for inclusion into the index, the number of pairs, the type of random responding, the correlation between the pairs, the skewness …
