Strategies of Self-Presentation II: Self-Verification01:17

Strategies of Self-Presentation II: Self-Verification

193
Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

PD Controller: Design

658
In automotive engineering, car suspension systems often employ Proportional Derivative (PD) controllers to enhance performance. PD controllers are utilized to adjust the damping force in response to road conditions. A controller, acting as an amplifier with a constant gain, demonstrates proportional control, with output directly mirroring input.
Designing a continuous-data controller requires selecting and linking components like adders and integrators, which are fundamental in Proportional,...

PI Controller: Design

1.3K
Proportional Integral (PI) controllers are a fundamental component in modern control systems, widely used to enhance performance and mitigate steady-state errors. They are particularly effective in applications such as automatic brightness adjustment on smartphones, where they excel at mitigating steady-state errors for step-function inputs. Unlike PD controllers, which require time-varying errors to function optimally, PI controllers leverage their integral component to address residual...

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.

Group Design

10.6K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

    Summary

    A new tactile-triggered system offers improved prosthetic hand control by using touch signals instead of surface electromyogram (sEMG) signals. This method enhances grasping stability and reduces user fatigue, outperforming traditional EMG pattern recognition.

    Area of Science:

    • Biomedical Engineering
    • Robotics
    • Human-Computer Interaction

    Background:

    • Surface electromyogram (sEMG) based prosthetic hand control faces challenges due to signal variability and limited residual muscle function in amputees.
    • Tactile signals offer crucial haptic feedback for object manipulation, presenting a potential alternative or supplement to EMG for prosthetic control.

    Purpose of the Study:

    • To propose and validate a novel tactile-triggered method for motion intent recognition and prosthetic hand control.
    • To compare the performance of the tactile-triggered system against traditional EMG pattern recognition (EMG-PR) control.

    Main Methods:

    • Implemented a finite state machine (FSM) using a multi-axis tactile sensor for tactile-triggered motion intent recognition.
    • Developed an integrated prosthetic hand control system incorporating the tactile-triggered method.
    • Conducted validation tests with both able-bodied and transradial-amputee participants, comparing against EMG-PR.

    Main Results:

    • The tactile-triggered control strategy demonstrated effective prosthetic hand opening/closing control, enabling stable grasping of various objects.
    • This method significantly reduced performance degradation due to arm posture changes compared to EMG-PR.
    • The system exhibited superior grasping stability and avoided user muscle fatigue.

    Conclusions:

    • The tactile-triggered approach presents a promising, stable, and user-friendly prosthetic hand control strategy.
    • It can serve as a non-EMG control paradigm or a complementary system to myoelectric control.
    • This method addresses key limitations of current EMG-based prosthetic control systems.
