Journal of Law Enforcement
Abstract: Although law enforcement officers may change holsters several times during their careers, the effects of holster changes on performance are not known. The current research investigated the reaction time costs associated with changing from lower to higher retention level holsters. The results indicated that Level III holsters are slower than Level II holsters during the initial change. However, if the holster’s mechanical retention device manipulations can be combined, the reaction time differences are negligible.

The Journal of Law Enforcement
Abstract: Police car visibility is an important consideration for both Community Oriented Policing and safety. Highly visible police cars promote a sense of police presence in communities, and presumably, they are less likely to be hit by other motorists. The present research included two experiments that investigated police car visibility. Experiment 1 used detection and categorization tasks to investigate which paint scheme, black/white or white, was better detected and categorized. Experiment 2 used a categorization task that included stimuli consisting of complete and partially-complete police cars to investigate the defining components of police cars. The results indicated that black/white police cars were better categorized than white, but white was better detected than black/white. Further, black/white paint was a dominant component that overshadowed the effects of light bars, make/model, or markings. Finally, light bars were more important than markings for defining police cars.

Abstract: Computational cognitive models are used to validate psychological theories of cognition, to formally describe how complex tasks are performed, and to predict human performance on novel tasks. Most cognitive models have very limited models of how the body interacts with the environment. The present research examines a simple human-machine interaction task and a simple object manipulation task. A cognitive model is integrated with a human avatar within a virtual environment in order to model both tasks.

The Journal of Law Enforcement
Abstract: The current project investigated the efficacy of a train-the-trainer active shooter response program that was used to provide patrol officers with the ability to resolve active shooters. Specifically, the transfer of information from subject matter experts, to local trainers, to officers at home agencies was examined, as well as the retention of declarative and procedural knowledge. The train-the-trainer paradigm was found to be a viable method for active shooter response training. Regarding skills, evaluating thresholds, and handling persons depreciated the fastest and the data indicated those skills need retraining at least every six months.

College Student Journal
Abstract: The study examined Draw-a-Scientist-Test (DAST) images solicited from 212 undergraduate students for the presence of traditional gender stereotypes. Participants were 100 males and 112 females enrolled in psychology or computer science courses with a mean age of 21.02 years. A standard multiple regression generated a model that accounts for the variability in the sexes of drawings consistent with past findings. The focus of this research, however, was in comparing the results of our sample (college students) with previous studies that have that have used the DAST with much younger (e.g., elementary-aged) students. Results were strikingly similar, suggesting either that gender stereotypes are widely persistent even among college science majors, or that the DAST may not be a particularly sensitive measure despite its wide use.

Abstract: The current research sought to construct a computational model of human navigation for virtual three dimensional environments. The model was implemented within the ACT-R cognitive architecture. The navigation model incorporates visual search, encoding object features and spatial relationships, motion, obstacle avoidance, and incidental visual memory.

Abstract: Search targets are typically remembered much better than other objects even when they are viewed for less time. However, targets have two advantages that other objects in search displays do not have: they are identified categorically before the search and finding them represents the goal of the search task. The current research investigated the contributions of both of these types of information to the long-term visual memory representations of search targets. Participants either completed a predefined search or a unique-object search in which targets were not defined with specific categorical labels before searching. Subsequent memory results indicated that search target memory was better than distractor memory even following ambiguously defined searches and when the distractors were viewed significantly longer. Superior target memory appears to result from a qualitatively different representation than those of distractor objects, indicating that decision processes influence visual memory.

Abstract: Although law enforcement officers may change holsters several times during their careers, the effects of holster changes on performance are not known. The current research investigated the reaction time costs associated with changing from lower to higher retention level holsters. The results indicated that Level III holsters are slower than Level II holsters during the initial change. However, if the holster’s mechanical retention device manipulations can be combined, the reaction time differences are negligible.

Abstract: Police car visibility is an important consideration for both Community Oriented Policing and safety. Highly visible police cars promote a sense of police presence in communities, and presumably, they are less likely to be hit by other motorists. The present research included two experiments that investigated police car visibility. Experiment 1 used detection and categorization tasks to investigate which paint scheme, black/white or white, was better detected and categorized. Experiment 2 used a categorization task that included stimuli consisting of complete and partially-complete police cars to investigate the defining components of police cars. The results indicated that black/white police cars were better categorized than white, but white was better detected than black/white. Further, black/white paint was a dominant component that overshadowed the effects of light bars, make/model, or markings. Finally, light bars were more important than markings for defining police cars.

Abstract: Computational cognitive models are used to validate psychological theories of cognition, to formally describe how complex tasks are performed, and to predict human performance on novel tasks. Most cognitive models have very limited models of how the body interacts with the environment. The present research examines a simple human-machine interaction task and a simple object manipulation task. A cognitive model is integrated with a human avatar within a virtual environment in order to model both tasks.

The Journal of Law Enforcement
Abstract: The current project investigated the efficacy of a train-the-trainer active shooter response program that was used to provide patrol officers with the ability to resolve active shooters. Specifically, the transfer of information from subject matter experts, to local trainers, to officers at home agencies was examined, as well as the retention of declarative and procedural knowledge. The train-the-trainer paradigm was found to be a viable method for active shooter response training. Regarding skills, evaluating thresholds, and handling persons depreciated the fastest and the data indicated those skills need retraining at least every six months.

College Student Journal
Abstract: The study examined Draw-a-Scientist-Test (DAST) images solicited from 212 undergraduate students for the presence of traditional gender stereotypes. Participants were 100 males and 112 females enrolled in psychology or computer science courses with a mean age of 21.02 years. A standard multiple regression generated a model that accounts for the variability in the sexes of drawings consistent with past findings. The focus of this research, however, was in comparing the results of our sample (college students) with previous studies that have that have used the DAST with much younger (e.g., elementary-aged) students. Results were strikingly similar, suggesting either that gender stereotypes are widely persistent even among college science majors, or that the DAST may not be a particularly sensitive measure despite its wide use.
