Reinforcement Schedules Modulate Discriminative Stimulus Properties Of 3,4-Methylenedioxymethamphetamine And Cocaine, Daniel Kueh

Masters Theses

Drug discrimination is a model used to assess the subjective effects of different psychoactive drugs such as 3,4-methylenedioxymethamphetamine (MDMA) and cocaine. However, results from MDMA discrimination studies across different laboratories have not been consistent. Possible confounds for this inconsistency may include the use of different reinforcement schedules such as the fixed-ratio 20 (FR20) and the variable interval 15 seconds (VI15 s) during discrimination training. Studies examining the effects of these two schedules on the discriminative stimulus properties of MDMA and cocaine have not been conducted. Thus, the present study compared the FR20 and the VI15 s schedules to determine their …

The Effects Of Gender And Regional Dialect On Performance In Aviation Communication, Erin E. Mccollum

Master's Theses - Daytona Beach

The purpose of this study was to analyze the performance effects of gender and regional dialect on air traffic control statement recall. Sixty-one student volunteers participated in the experiment. Thirty-one participants held a pilot’s license and 30 participants had no flight experience. Each participant listened to one CD with 60 ATC statements each representing a male and female voice and New England, Southern, and General American dialect. Participants were asked to recall exactly what they heard. If the participant could not understand what they heard, they requested a repeat. The participant’s performance was recorded to CD and analyzed. Demographic questionnaires …

The Effects Of Task Structure And Group Target Monetary Incentives On Social Loafing, Nelson R. Eikenhout

Dissertations

Social loafing refers to the decrease in individual performance output that occurs when individuals perform a task in groups in which the output is pooled. Pooled output refers to the performance of all group members added together to get a total group output. Therefore, because all group members contribute to a single group outcome, individual performance output is obscured. This study examined the following questions. First, what are the effects of the method of pooling the output (additive vs. disjunctive) on individuals who work on a concurrent task in small groups? Second, what are the effects of group target based …

A Behavioral Account Of Remembering: Precurrent Behavior And Mediation Of Delayed Matching To Sample, David W. Sidener

Dissertations

Although “memory” research and theory often come under the domain of cognitive psychology, these areas may also be seen as being open to radical behavioral interpretations. Delayed matching to sample (DMTS) preparations have often been used to study performance that involves the occurrence of behavior some time after the presentation of a relevant stimulus, or what is typically called short-term memory (STM). The current study involved three experiments that provided evidence for the role of overt behavior in the mediation of DMTS performance in five-year-old children. Experiments 1 and 2 support the assertion that sample-specific, differential mediating behavior (in the …

Pilot Performance And Eye Movement Activity With Varying Levels Of Display Integration In A Synthetic Vision Cockpit, Julie Michele Stark

Psychology Theses & Dissertations

The primary goal of the present study was to investigate the effects of display integration in a simulated commercial aircraft cockpit equipped with a synthetic vision display. Combinations of display integration level (low/high), display view (synthetic vision view/traditional display), and workload (low/high) were presented to each participant. Sixteen commercial pilots flew multiple approaches under IMC conditions in a moderate fidelity fixed-base part-task simulator. Pilot performance data, visual activity, mental workload, and self-report situation awareness were measured.

Congruent with the Proximity Compatibility Principle, the more integrated display facilitated superior performance on integrative tasks (lateral and vertical path maintenance), whereas a less …

Brighter Noise: Sensory Enhancement Of Perceived Loudness By Concurrent Visual Stimulation, Yoav Arieh, Eric C. Odgaard, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Two experiments investigated the effect of concurrently presented light on the perceived loudness of a low-level burst of white noise. The results suggest two points. First, white noise presented with light tends to be rated as louder than noise presented alone. Second, the enhancement in loudness judgments is resistant to two experimental manipulations: varying the probability that light accompanies sound and shifting from a rating method to a forced choice comparison. Both manipulations were previously shown to eliminate a complementary noise-induced enhancement in ratings of brightness. Whereas noise-induced enhancement of brightness seems to reflect a late-stage decisional process, such as …

Pediatric Amputations: Ptsd, Behavioral Tendencies And Quality Of Life, Adriana Macias Chamorro

Loma Linda University Electronic Theses, Dissertations & Projects

The present study examined children and adolescents between 11-18 years of age who had experienced traumatic amputations due to an acute physical injury (burns, severing, and crushing accidents). In order to account for variance which may have impacted the results of the study, evaluations were conducted between a group of children/adolescents with amputations and a comparison group of children/adolescents who had been hospitalized due to a non-head injury, non-death motor vehicle accident. The goal of this study was to assess symptoms of PTSD, provide a description of the internalized and externalized behaviors, and examine the quality of life (QOL)(health habits, …

Comparative And Contributive Effects Of Process And Human Performance Improvement Strategies, Joseph R. Sasson

Dissertations

Organizational leaders know that the success of their organization depends on the organization's ability to either produce better products or produce equally good products at a lower cost to consumers. Interventions aimed at improving organizational performance stem from two primary perspectives. One perspective emphasizes changing system factors (e.g., equipment and processes) and the other perspective emphasizes changing human performance factors (e.g., performance specifications and behavioral consequences). The current study evaluated the comparative and contributive effects of process improvement techniques (Kock, 1999; Melan, 1992; Rummler & Brache, 1995) and human performance improvement techniques (Daniels, 1989; Gilbert, 1996; Rummler & Brache, 1995), …

Why Distinctive Information Reduces False Memories: Evidence For Both Impoverished Relational-Encoding And Distinctiveness Heuristic Accounts, Amanda C. Gingerich, C. S. Dodson

Scholarship and Professional Work - LAS

Two accounts explain why studying pictures reduces false memories within the Deese-Roediger-McDermott paradigm (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995). The impoverished relational-encoding account suggests that studying pictures interferes with the encoding of relational information, which is the primary basis for false memories in this paradigm. Alternatively, the distinctiveness heuristic assumes that critical lures are actively withheld by the use of a retrieval strategy. When participants were given inclusion recall instructions to report studied items as well as related items, they still reported critical lures less often after picture encoding than they did after word encoding. …

On The Conceptual And Linguistic Activity Of Psychologists: The Study Of Behavior From The 1890s To The 1990s And Beyond, David E. Leary

Psychology Faculty Publications

In the early twentieth century psychology became the study of "behavior." This article reviews developments within animal psychology, functional psychology, and American society and culture that help explain how a term rarely used in the first years of the century became not only an accepted scientific concept but even, for many, an allencompassing label for the entire subject matter of the discipline. The subsequent conceptual and linguistic activity of John B. Watson, Edward C. Tolman, Clark L. Hull, and B.F. Skinner, as they attempted to explain "behavior" throughout the course of the twentieth century, is then discussed. Finally, the article …

Exposure To Televised Alcohol Ads And Subsequent Adolescent Alcohol Use, Alan W. Stacy, Jennifer Zogg, Jennifer Unger, Clyde W. Dent

CGU Faculty Publications and Research

Objective: To assess the impact of televised alcohol commercials on adolescents, alcohol use. Methods: Adolescents completed questionnaires about alcohol commercials and alcohol use in a prospective study. Results: A one standard deviation increase in viewing television programs containing alcohol commercials in seventh grade was associated with an excess risk of beer use (44%}, wine/liquor use (34%}, and 3-drlnk episodes (26%} in eighth grade. The strength of associations varied across exposure measures and was most consistent for beer. Conclusions: Although replication is warranted, results showed that exposure was associated with an increased risk of subsequent beer consumption and possibly other consumption …

Measuring Coping : Evaluating The Psychometric Properties Of The Cope, Kathleen J. Donoghue

Theses : Honours

Research into coping has been hampered by the limited psychometric properties of the available instruments, particularly with respect to the internal validity of multidimensional measures. The purpose of this paper was to review research relevant to the measurement of coping, and to evaluate the COPE based on this literature. The COPE is a widely used multidimensional self-report instrument containing 15 subscales to measure different ways of coping. Claims that the COPE has good factorial validity warrant further examination in light of widespread criticism aimed at coping checklists in general. The present review found mounting evidence that the internal structure of …

Crisp And Fuzzy Signal Detection Theory And Pilot Weather Judgment: Implications For Vfr Flights Into Imc, Joseph T. Coyne

Psychology Theses & Dissertations

Weather represents one of the greatest hazards to general aviation (GA), accounting for 15% of the GA accident fatalities. Of the fatal weather accidents 90% are attributed to visual flight rules (VFR) flight into instrument meteorological conditions (IMC). The situation assessment hypothesis suggests that pilots may inadvertently enter IMC because they lack the sensitivity needed to distinguish between visual meteorological conditions (VMC) and IMC. An alternative hypothesis is that pilots recognize conditions have deteriorated but are motivated by some other factor, such as pressure from passengers. The present study uses Jensen's Pilot Judgment Model and Signal Detection Theory to explain …
