Multi-input and Multi-variable systems

93
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

Types of Selection01:46

Types of Selection

39.9K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Graded Potential01:19

Graded Potential

3.5K
Graded potentials are localized fluctuations in the cell membrane's electrical charge, commonly found in the dendrites of neurons. The magnitude of these potential changes depends on the strength of the initiating stimulus. In a membrane at its resting potential, a graded potential signifies a voltage shift either above -70 mV or below -70 mV.
Graded potentials fall into two categories: depolarizing and hyperpolarizing. Depolarizing graded potentials typically occur when sodium (Na+) or...

Integration of Synaptic Events01:28

Integration of Synaptic Events

1.4K
Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability...

The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.2K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Controls in Experiments01:13

Controls in Experiments

6.9K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Area of Science:

  • Psychology
  • Behavioral Science
  • Verbal Behavior Analysis

Background:

  • Skinner's analysis of verbal behavior posits that multiple stimuli can exert control over selection-based responses.
  • Understanding convergent multiple control is crucial for explaining complex verbal phenomena.
  • Experimental modeling provides a method to test theoretical constructs in behavior analysis.

Purpose of the Study:

  • To experimentally model summation in convergent multiple control over selection-based verbal behavior.
  • To investigate how the combination of controlling stimuli affects verbal selections.
  • To provide empirical support for theoretical aspects of Skinner's analysis of verbal behavior.

Main Methods:

  • Eight undergraduate students participated in a divergent-convergent tact training.
  • A three-choice match-to-sample task was employed to establish selection-based tacts.
  • Pre and posttest trials assessed responses to single stimuli and two-stimulus compounds.

Main Results:

  • During posttests, compounds predominantly occasioned selections of the textual stimulus related to both elements, demonstrating convergent control.
  • Textual stimuli were more frequently selected in the presence of compounds than isolated controlling elements.
  • This indicates that combined stimuli exert a stronger influence on selection-based verbal behavior.

Conclusions:

  • The study successfully modeled summation in convergent multiple control.
  • Findings support the theoretical importance of Skinner's (1957) analysis of verbal behavior.
  • Convergent control over selection-based verbal behavior was empirically demonstrated.
