Tone Detection

Tone detection is the process of identifying a speaker’s emotional state, attitude, or communicative intent from how a message is expressed rather than from its words alone. In psychology, it relies on cues such as pitch, loudness, speech rate, pauses, emphasis, word choice, and conversational context, which people integrate to interpret emotions including enthusiasm, irritation, uncertainty, or empathy. Researchers use tone detection to study social perception, interpersonal communication, emotional regulation, and misunderstandings in spoken or written interactions. Its principles also inform clinical assessment, communication training, and computational systems designed to recognize affect while accounting for cultural and situational differences.

2011

We have developed a device (Twister) to study the regulation of tonic muscle activity during active postural maintenance. Twister measures torsional resistance and muscular responses in standing subjects during twisting of the body axis. The device can be flexibly configured to study various aspects of tonic control across the neck, trunk, and/or hips.

Alterations in Muscle Tone ll

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...

Biaxial Basal Tone and Passive Testing of the Murine Reproductive System Using a Pressure Myograph

This protocol utilized a commercially available pressure myograph system to perform pressure myograph testing on the murine vagina and cervix. Utilizing media with and without calcium, the contributions of the smooth muscle cells (SMC) basal tone and passive extracellular matrix (ECM) were isolated for the organs under estimated physiological conditions.
