Non-Verbal Cues

Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Attention refers to the limited human ability to select some information for processing at the expense of other stimuli in the environment. Attention operates in all sensory modalities: vision, hearing, touch, even taste and smell. It is most often studied in the visual domain though. A common way to study visual attention is with a spatial cueing paradigm. This paradigm allows researchers to measure the consequences of focusing...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Why is it relatively hard to remember everything on a shopping list if it includes more than just a handful of items? Why is it possible to remember a phone number that one just heard, but not two or three phone numbers at once? Why is it difficult to remember names when several new people are introduced at the same time? The answer has to do with the fact that over short-durations people rely on a specialized memory system...

Verbal Priming

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human memory seems to work in two broad ways. Like modern computers, the human mind has explicit, or declarative, memory: ask a question, and a person gives the best answer they can. Input a query, and a computer program returns the contents of the relevant parts of its stored memory. Humans also have a second kind of memory system, one not really typical of computers, one that experimental psychologists call implicit. Implicit...

We discuss a novel method forviewpoint-rotation of visual stimuli, and demonstrate using a mirror stereoscopethe three-dimensional percept of rotation-in-depth. The technique can be used to investigate the role of stereoscopic cues in encoding viewpoint-rotated figures.
FAQs
Operational definitions translate broad observations, such as a gesture, gaze shift, posture, or pause, into coding rules that observers can apply consistently. These rules establish which behavior counts, how it is recorded, and how categories become analyzable variables. Clear definitions reduce ambiguity, support reproducibility, and help ensure that statistical comparisons reflect observed behavior rather than differing interpretations.
Observer agreement indicates whether different analysts code the same interaction in similar ways. Low agreement may reveal unclear categories, inconsistent application of rules, or cues that are difficult to distinguish. Assessing agreement before interpreting patterns strengthens reliability, while poor results signal a need to refine the coding scheme or reconsider which observations can support dependable statistical conclusions.
Descriptive methods summarize how often cues occur, how they vary, and how they differ across people or conditions. Inferential methods then examine associations or differences beyond the observed summaries. This distinction helps analysts avoid treating an isolated gesture, expression, or vocal change as a general pattern without considering the broader sample and research conditions.
Analysts can code non-verbal signals alongside spoken communication and compare the resulting variables across an interaction. A cue may reinforce what a person says, add information, or appear inconsistent with the verbal message. Including facial expression, gesture, posture, gaze, pitch, or pauses allows statistical analysis to examine these relationships rather than treating spoken language as the only relevant source of evidence.
A study typically begins by selecting interactions or participants through a defined sampling approach. Researchers then establish operational coding rules, record selected cues as variables, and evaluate agreement among observers. After checking the quality of the coded data, they use descriptive or inferential statistics to examine patterns, associations, or differences relevant to the research question.
The approach supports research in psychology, education, healthcare, human-computer interaction, and social science. Statistical results can show how observed cues vary across people or conditions and whether they relate to spoken communication. In these settings, careful sampling, explicit coding, and reliability testing help researchers produce findings that are more interpretable, reproducible, and relevant to the studied interaction.
