Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch

7.9K
The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

Tactile and Chemical Senses01:27

Tactile and Chemical Senses

808
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Frustration and Conflict: Approach-Approach, Approach-Avoidance01:20

Frustration and Conflict: Approach-Approach, Approach-Avoidance

540
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

692
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Sensitivity, Specificity, and Predicted Value01:13

Sensitivity, Specificity, and Predicted Value

1.4K
In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.
Sensitivity is the...

    Area of Science:

    • Neuroscience
    • Human Sensory Perception
    • Virtual Reality

    Background:

    • The two-point discrimination test assesses tactile sensory acuity.
    • Understanding sensory integration is crucial for human-computer interaction and neuroscience.

    Purpose of the Study:

    • To introduce a novel sensory test combining tactile and visual stimuli.
    • To investigate how vision and taction integrate to form a unified percept, especially during sensory conflict.
    • To inform the design of haptic feedback systems and virtual reality accessories.

    Main Methods:

    • A new test was developed where one stimulus is tactile (monofilament) and the other is visual (virtual reality).
    • The test was conducted on the leg above the knee.
    • Results were compared to the traditional two-point discrimination test.

    Main Results:

    • The study provides data on the integration of visual and tactile sensory information.
