This large class primarily consists of freshman and sophomores majoring in related fields, like Psychology, Neuroscience, or Cognitive Science. One of the challenges I face in the classroom is teaching students to appreciate how data are obtained in the process of performing experiments.

Reliability in Psychology Experiments

Source: Laboratories of Gary Lewandowski, Dave Strohmetz, and Natalie Ciarocco—Monmouth University In order to study something scientifically, a researcher needs to determine a way to quantify it. However, psychological constructs can be challenging to measure and quantify. This video examines reliability in the context of content analysis. A recent study in the journal Pediatrics reported that 4-year-olds who watched a fast-paced cartoon had worse performance on cognitive tasks, such as...

Eye Tracking in Cognitive Experiments

Eye tracking as the name suggests involves tracking of eye-movements. It is a non-invasive, sensitive tool that quantifies and measures eye-movements to describe an individuals' cognitive state. An eye-movement between two fixation points is called a saccade, which is one of the fastest motor movements in our body. By observing the profiles of these eye movements, scientists can better understand neural deficits in patients with cognitive impairments. In this video, we will first look at an...

Introduction to Cognitive Psychology

2025
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing. This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

A fully automated protocol for rodent operant conditioning is proposed. The protocol relies on precise temporal control of behavioral events to investigate the extent to which this control influences neural activity underlying sensorimotor integration and cognitive control experiments.

Operationalization turns an abstract process such as remembering or attending into measurable variables. A researcher specifies what participants will do and which result will be recorded, such as recall, accuracy, reaction time, or a response choice. This makes the process testable and allows outcomes from different experimental conditions to be compared systematically.
Changing task demands or the information presented allows researchers to examine how different conditions influence cognitive performance. Comparing responses across those conditions can show whether a result supports one explanation of information processing over another. Controlling other potential influences is important because it helps link observed differences to the intended manipulation.
These outcomes provide complementary evidence about performance during a cognitive task. Reaction time indicates how quickly a response occurs, while accuracy, recall, and response choices show different aspects of what participants produce. Examining these measures together can reveal distinct patterns across conditions and strengthen conclusions about how information is processed.
A typical design begins by selecting a cognitive process and converting it into measurable variables. Researchers then establish the conditions to manipulate, decide which outcomes to record, and control potential confounds. Finally, they compare performance across conditions using measures such as reaction time, accuracy, recall, or response choices to evaluate competing explanations.
Their findings can inform education, clinical assessment, human-computer interaction, and intervention design. For example, evidence about memory, attention, language, or decision-making can guide how researchers understand performance in these settings. The experiments are useful when a question requires controlled comparisons of cognitive outcomes rather than descriptions of behavior alone.
They provide evidence about mental processes underlying behavior and help distinguish competing explanations of cognition. Results can refine theories concerning memory, attention, language, and decision-making by showing how outcomes change under different task demands or information conditions. This connection between controlled evidence and theory supports broader psychological understanding of information processing.
