Training Human Factors Psychology Dr. Steve
Background • Four types of factors that lead to poor performance: • The environment is in the way • e.g. lack of proper tools to perform the job • Employees lack skill or knowledge • this can can be caused by lack of feedback • There are no, few, or improper incentives • doing a good job could result in gaining more work • Employees are not internally motivated • e.g. certain jobs that lack pride or meaning (flipping burgers)
Personnel Selection • Can be seen as the first approach taken to maximize the skills and knowledge needed by an employee to perform a job • Focus on identifying reliable means of predicting future job performance • Methods include: interviews, work histories, background checks, tests, references, & work samples
Personnel Selection • Can be seen in terms of signal detection theory: • hit = hiring a person who will be good at the job • miss = not hiring someone who would do a good job • false alarm = hiring someone who ends up being unacceptable or doing a poor job • correct rejection = not hiring someone who, in fact, would not do a good job if they had been hired
Basics of Selection • First a thorough job analysis is needed • Identify & prioritize KSAs • Find the applicants who have the KSAs or have the ability to acquire them • Want a measure that is highly correlated with ultimate job performance (i.e., criterion-related validity)
Selection Tests and Procedures • Selection errors can have serious negative consequences for the company • cost related to high turnover • legal problems • (e.g. adverse impact) • low employee moral or resentment • supervisors having to spend too much time on documentation of problems
Commonly used Selection Test and Procedures • Measures of Cognitive Ability • e.g. general ability, verbal ability, numerical ability, perceptual speed, memory... • used as valid predictors of job performance • Measures of Physical Ability and Psychomotor Skills • e.g. static strength, dynamic strength, gross body coordination, manual dexterity, stamina ... • e.g. UPS worker
Commonly used Selection Test and Procedures • Personality Assessment • clinical or personality dimensions • e.g. MMPI • Work Samples • applicants complete a sample of work necessary for successful job performance • e.g. making a basket for an NBA player • Structured Interviews
Future Trends in Human Performance Intervention • Accelerating turnover of knowledge • Rapid advances in information technology • An increasingly diverse work force • Increasing international business competition

Training Program DesignSimplified Instructional System Design (ISD) model • Phase I – Front-End Analysis • Needs Assessment– to determine whether training is the most appropriate method • Organizational Analysis– determine where in the organization is training required, and whether training will be accepted by organization • Task Analysis– determine training objectives by examining tasks necessary to perform job • Trainee (Person) Analysis– determine KSA’s of potential trainees and who should receive training • Functional Specifications – defines the training objectives, performance requirements, and constraints
Training Program DesignSimplified Instructional System Design (ISD) model • Phase II – Design and Development • Generate Design Concepts • Story-boarding, cost-benefit analysis • Formative Evaluation • Focuses on process and usability, provides feedback so that design changes can be made prior to development • Full-Scale Development • Creating the medium to present the learning curriculum
Training Program DesignSimplified Instructional System Design (ISD) model • Phase III – System Evaluation • Develop Criteria – should be consistent with training objectives • Levels of Criteria (Kirkpatrick) for summative evaluation • Reaction – feedback from trainees as to whether they liked the training • Learning – test whether trainees learned the material • Behavioral – determine whether training led to measurable changes in performance on the job • Results – utility of training or how much cost savings was derived from implementing training • Design Evaluation Program • Collect/Analyze Data • Modify training based on empirical data
Guidelines for Instructional Development* • Training Validity:Instructional events that comprise the training method should be consistent with the cognitive, physical, or psychomotor processes that lead to mastery • Active Learning:Learner should be induced to produce the capability • e.g. practice behaviors, recall info from LTM, apply principles in doing task • Feedback Delivery:All available sources of relevant feedback should be used, & should be accurate, credible, timely, informative & constructive • Self-efficacy:Instructional processes should enhance trainee self-efficacy and expectations that the training will be successful and lead to valued outcomes • Trainee Aptitude:Training methods should be adapted to differences in trainee aptitudes and prior knowledge *Adapted from research by Campbell
Training Media Click for bad example of Audio Air Force Training Guide • Audio-Visual (AV) Material– videos, films, slide presentations, used to present info multiple times
Training Media Example of CAI • Interactive Multi-Media – computer driven training system using text, graphics, video, auditory information • Computer-Assisted Instruction (CAI) / Computer-Based Training (CBT)
Training Media • Simulation / Virtual Reality– imitation of the real environment
Training Media and Strategy Guidelines* Link to decision aid for selecting training media • Simulation:effective for teaching many tasks and skills e.g., perceptual motor skills, conceptual tasks, and team functions • Computer-based instruction:provide capability to review and branch and include skill diagnosis and remediation • Sound:provides helpful cues in instructional presentations • these cues can be satisfied with relatively low fidelity but extremely high timely executions • Induce Motivation:Instruction should provide feedback control of both stimulus and reinforcement variables • Reduce Cognitive Load: training features should limit the number of stimuli (and extraneous stimuli) presented at any one time to avoid requiring inordinate attention from students *Guidelines are a subset adapted from Salvendy’s Handbook of Human Factors and Ergonomics
control time – transfer time time savings %Transfer = X 100 = X 100 control time control time time savings training time Training Effectiveness Ratio (TER) = Transfer of Training • Transfer of Training – how well learning in one environment, enhances performance in another. • Issues of training efficiency: • What provides best learning in shortest time? • What will lead to longest retention? • What is most cost effective?
Negative Transfer • Negative Transfer– learning in one environment interferes with performance in the other. • caused when one learns different response to same or similar stimulus. • old response competes with new response for same stimulus. • must unlearn old response • ex: when switching from Lotus 1-2-3 to Excel software, the spreadsheets look the same, but require different commands for creating formulas and specifying cell ranges.
Guidelines for Enhancing Transfer • Generalizability:Provide practice in a variety of stimulus situations so that a student may generalize their knowledge • Transfer Goal:Use a rote or algorithmic approach if near transfer is the goal of instruction • Visual Demonstrations:Training which incorporates visual demonstrations provides positive transfer to real-world situations • Guided Training (training wheels):Gradually decrease the amount of cues, prompts, and guides such that none (that would not be found on the job) remain at the end of training • Functional vs. Physical fidelity:functional fidelity appears to be a stronger influence in transferring knowledge from the learning environment to the operational setting
Training System Fidelity • Fidelity– realism of the training device • Physical Fidelity– how realistic training device appears • Functional Fidelity– how well device trains concepts Fidelity Issues: • Expense – more realism, greater cost • Necessity – many tasks can be learned as well or better by simplifying task in training (lowered fidelity) • Negative transfer – if training environment is very close to real environment, then things that are different may lead to negative transfer.
Training Techniques • Overlearning - practice above & beyond that necessary for errorless performance • Increases resistance to extinction (improves retention) • Increases the ease of “re-learning” • Decreases reaction time • May lead to automaticity Overlearning Performance Practice Trials
Training Techniques • Embedded Training– controlled exercises called up and worked on by trainees operating actual equipment (in training mode) • Provides employees opportunities to practice skills in a variety of common situations to build automaticity • Allows employees to practice skills relevant to situations that might occur infrequently on the job (meltdown at nuclear power plant). • Sometimes referred to as “stimulation” because rather than simulate the equipment it injects signals (stimuli) into the actual equipment
Training Techniques • Part-Task Training– learn individual components of task separately, then join together later (segmentation) • Identify task components that are NOT interdependent • Identify most important components • De-emphasize certain components Ejector seat training is only one part of learning to fly
Training Techniques • Guided Training (training wheels)– prevents learner from making catastrophic errors • Avoids confusion in learning complex tasks • Don’t eliminate errors altogether (they’re learning material), but keep from making errors that impair learning
Training Techniques • Above Real-Time Training– practice trials that are faster than would be experienced on the job • Difficulty of practice assumed to make actual task seem easier. • Like swinging a weighted baseball bat in warm-ups then switching to standard bat in the game • Equivocal results in the research • Violates other principles for enhancing transfer (“train as you fight”)
Top 5 Specific Instructional Guidelines* • Use Advance Organizers: At beginning of training, the material/media should clearly inform the trainee of the learning objectives • Provide Knowledge of Results: During practice provide students with immediate knowledge of results about correct and incorrect answers • Develop Mental Models: Emphasize distinctive features which can be remembered in the form of mental pictures instead of abstract words • e.g. diagrams, pictures, charts, acronyms • Segment Training: Break down the overall learning task into manageable steps or unit when any of the following conditions exist: • lower ability students, complex material, & overall task composed of small parts • Part-task / Whole-task Training: Provide learner practice on specific components of the task for: a) simple task-practice in entirety, & b) complex task-practice in parts and then in entirety *Guidelines are a subset adapted from Salvendy’s Handbook of Human Factors and Ergonomics
