Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In a staggeringly complex and engaging world, it is crucial to selectively process some stimuli at the expense of others. Experimental psychologists call this ability attention. Specifically, visual attention refers to the ability to selectively process aspects of a visual scene. Many paradigms used to study visual attention involve brief, punctuated, and repeated trials. However, everyday situations often place sustained demands...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual masking is a term used by perceptual scientists to refer to a wide range of phenomena in which in an image is presented but not perceived by an observer because of the presentation of a second image. There are several different kinds of masking, many of them relatively intuitive and unsurprising. But one surprising and important type of masking is called Object Substitution Masking. It has been a focus of research in vision...

Uncertainty in Measurement: Accuracy and Precision
0 Views •
2020
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value. Suppose a quality control...

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Evaluating the Accuracy of Snap Judgments

Source: Diego Reinero & Jay Van Bavel—New York University Social psychologists have long been interested in the way people form impressions of others. Much of this work has focused on the errors people make in judging others, such as the exaggerated influence of central traits (such as "warm" and "cold"), the insufficient weight given to the context in which others' behavior takes place, and the tendency for people to make judgments that conform to their initial expectations about another.
FAQs
Clearly defined variables specify what researchers will observe, measure, or compare before collecting evidence. This reduces ambiguity about whether a study examines a behavior, mental process, or related interpretation. Precise definitions also help different researchers apply the same criteria, making findings easier to evaluate, compare, and reproduce across psychological studies.
Standardized procedures require researchers to collect information under consistent conditions rather than adapting methods according to personal expectations or preferences. Consistency limits opportunities for subjective decisions to influence results and allows differences in findings to be considered in relation to the phenomenon studied. This is especially important when psychological evidence comes from multiple participants or settings.
Researchers can reduce expectancy effects by planning methods and analyses transparently, using standardized measurement tools, and arranging independent review of the work. Preregistration records important plans before results are interpreted, while review by others provides an additional examination of procedures and conclusions. Together, these safeguards make subjective influence easier to identify and limit.
Accuracy supports conclusions that represent the phenomenon being studied, whereas objectivity addresses how researchers collect and interpret the evidence used to reach those conclusions. A study therefore needs both: a measurement approach can be carefully standardized yet still fail to represent the intended phenomenon, while an appropriate measure can be weakened by biased interpretation.
A study can begin by defining its variables and selecting reliable measurement tools, then apply standardized procedures during evidence collection. Researchers can preregister important plans, analyze data transparently, and seek independent review of methods and conclusions. This sequence creates a documented path from the research question to the reported outcome and supports reproducibility.
Accuracy and objectivity matter in laboratory studies, clinical assessment, and applied research because each context uses evidence to evaluate behavior or mental processes. In clinical and applied settings, trustworthy conclusions can influence how psychological information is understood and used. In laboratory work, the same standards help others assess whether findings can be reproduced.
They examine whether variables were clearly specified, measurements were dependable, procedures were applied consistently, and data analysis was reported transparently. Preregistration and independent review add records and scrutiny beyond the original research team. When these features align, other psychologists have a stronger basis for evaluating the conclusion and determining whether similar work can reproduce it.
