Decontamination for Laboratory Biosafety

2023
Robert M. Rioux and Zhifeng Chen, Pennsylvania State University, University Park, PA Decontamination is essential for laboratory biosafety, as the accumulation of microbial contamination in the laboratory can lead to the transmission of disease. The degree of decontamination can be classified as either disinfection or sterilization. Disinfection aims to eliminate all pathogenic microorganisms, with the exception of bacterial spores on lab surfaces or equipment. Sterilization, on the other hand,...

The analytical balance is the common piece of equipment in the scientific laboratory. These highly precise instruments can measure down to ten thousandths or even hundred thousandths of a gram. The triple beam balance is a type of scale that uses counterweights on a three rider beams to counterbalance the sample in the pan. On the other hand, modern analytical balances use a complex system of electronic sensors to accurately mass a substance. The analytical balance is so sensitive that it...

Making Solutions in the Laboratory

2023
The ability to successfully make solutions is a basic laboratory skill performed in virtually all biological and chemical experiments. A solution is a homogenous mixture of solute dissolved in bulk liquid known as the solvent. Solutions can be described by their solute concentration, a measure of how much solute is present per unit of solution. In this video, a step-by-step procedure for how to make a water-based, or aqueous, solution for biological applications is presented. The video...

Control works by holding relevant conditions steady while changing the factor under investigation. Lighting, instructions, timing, and participant interactions can be regulated so that differences in responses are more plausibly associated with the manipulated independent variable rather than uncontrolled influences. This arrangement strengthens examination of cause-and-effect relationships in psychological behavior and physiological measurement.
The independent variable is the factor that researchers deliberately manipulate to examine its influence on participants’ responses. Behavioral or physiological measurements then provide evidence about possible effects under the specified conditions. Separating the manipulated factor from the recorded response helps researchers evaluate theoretical explanations of perception, learning, memory, emotion, or social behavior.
Standardized instructions and timing reduce differences in how participants encounter the study conditions. Consistent participant interactions and regulated lighting further limit variation that could otherwise affect behavior or physiological responses. By applying comparable procedures across participants, researchers can improve reliability and make results easier to compare across studies investigating similar psychological processes.
Researchers first regulate relevant conditions, including lighting, instructions, timing, and participant interactions. They then manipulate an independent variable and record the resulting behavioral or physiological responses. The collected measurements can be examined for patterns associated with that manipulation, while the controlled procedure supports comparisons among participants and contributes to systematic psychological experimentation.
A controlled study can produce behavioral measurements, physiological responses, or both. These outcomes allow researchers to examine how participants respond when an independent variable changes under regulated conditions. Such measurements support investigations of perception, learning, memory, emotion, and social behavior, while also contributing evidence for psychological theories and more reliable comparisons across studies.
Laboratory research is useful when psychologists need to isolate potential cause-and-effect relationships and reduce confounding influences. Its applications include studying perception, learning, memory, emotion, and social behavior. Findings can also inform clinical assessment, educational practice, and theories of human behavior, extending controlled experimental evidence beyond the immediate study context.
