Steps in the Modeling Process01:14

Steps in the Modeling Process

687
Albert Bandura's theory of observational learning identifies four critical processes: attention, retention, motor reproduction, and reinforcement or motivation.
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

6.3K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Introduction to Statistical Process Control

665
Statistical Process Control (SPC) is a method used to monitor and control quality within processes, particularly in manufacturing and service delivery, by employing statistical methods. SPC aims to distinguish between natural (common cause) variation and variation due to specific changes or events (special cause), allowing for timely improvements and sustained quality. The control chart, a pivotal tool in SPC, visually displays data over time alongside a central line of upper and lower control...

Understanding Consciousness01:23

Understanding Consciousness

2.2K
Consciousness can be defined as the state of being aware of and able to think about one's existence, sensations, and surroundings. It encompasses two major components: awareness and arousal. Awareness pertains to the recognition of environmental stimuli and internal states. At the same time, arousal refers to the physiological readiness to engage with these stimuli, which varies significantly between states like sleep and wakefulness.
Sleep, a crucial state, is characterized by reduced...

Uncertainty in Measurement: Accuracy and Precision

104.1K
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.

Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

26.5K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Summary
This summary is machine-generated.

Fall-related anxiety impairs gait by increasing internal focus, reducing cognitive resources for concurrent tasks. This internal focus, whether from threat or instruction, hinders walking and dual-task performance.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Biomechanics

Background:

  • Fall-related anxiety can reduce attentional processing efficiency during gait.
  • This impairment limits cognitive resources for simultaneous tasks like conversation or navigation.

Purpose of the Study:

  • To evaluate the interpretation that fall-related anxiety impairs processing efficiency by directing attention internally.
  • To investigate the impact of internal focus on cognitive resources during gait.

Main Methods:

  • Fifteen young adults performed a precision stepping task under single- and dual-task conditions.
  • Conditions included Baseline, Threat (elevated platform), and Internal focus of attention.
  • Cognitive dual-task costs and stepping accuracy were measured.

Main Results:

  • Cognitive dual-task costs were significantly greater during Threat and Internal conditions compared to Baseline.
  • Highest costs were observed in individuals with high Threat-induced conscious motor processing.
  • Stepping accuracy was poorer in dual-task trials during Threat and Internal conditions.

Conclusions:

  • Findings support the hypothesis that anxiety-induced internal focus causes attentional processing inefficiencies in gait.
  • Consciously attending to movement depletes cognitive resources needed for secondary tasks during walking.
