Blind Procedures02:07

Blind Procedures

13.5K
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Blinding01:11

Blinding

4.0K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Global Climate Change

28.9K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Rates of Change01:20

Rates of Change

119
The rate of change is a central concept in mathematics that quantifies how one variable varies in response to another. It serves as a foundational tool in modeling dynamic systems across disciplines such as physics, biology, economics, and engineering. Understanding both average and instantaneous rates of change enables the analysis of behavior in functions that describe real-world phenomena.Average Rate of ChangeFor a function f(x) defined over an interval [x1,x2], the average rate of change...

Work Done During Volume Change01:17

Work Done During Volume Change

5.2K
In mechanics, work is done on an object when the force acting on it displaces the object. In thermodynamics, work done on a system can be estimated when the system's volume changes during any thermodynamic process.
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as

Le Chatelier's Principle: Changing Temperature02:19

Le Chatelier's Principle: Changing Temperature

35.5K
Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in the value of the equilibrium constant, K. When an equilibrium shifts in response to a temperature change, however, it is re-established with a different relative composition that exhibits a different value for the equilibrium constant.
To understand this phenomenon, consider the elementary reaction:

Summary

Change blindness, where visual changes go unnoticed, affects pigeons like humans. The flicker paradigm shows pigeons

Area of Science:

  • Cognitive Psychology
  • Comparative Cognition
  • Neuroscience

Background:

  • Change blindness is a phenomenon where significant visual changes go undetected.
  • The flicker paradigm, involving alternating visual displays with a blank inter-stimulus interval (ISI), effectively induces change blindness in laboratory settings.
  • This paradigm's simplicity and clear operational definition make it suitable for comparative studies.

Purpose of the Study:

  • To investigate change blindness in pigeons using a variant of the flicker paradigm.
  • To compare pigeons' change detection abilities with human performance.
  • To explore the role of selective spatial attention in pigeons.

Main Methods:

  • A modified flicker paradigm was implemented in operant chambers for pigeons.

  • Two visual displays were presented alternately, separated by a blank inter-stimulus interval (ISI).
  • Pigeons' ability to detect the location of changes between displays was measured.

    • Main Results:

    • Pigeons exhibited impaired change detection when displays were separated by a blank ISI, similar to humans.
    • Pigeons' performance suggests an active, location-by-location search process requiring selective attention.
    • Change detection in pigeons was consistent with findings in human visual perception.

    Conclusions:

    • Change blindness is not exclusive to human visual perception but may be a general consequence of selective attention.
    • The flicker paradigm is a viable tool for studying selective spatial attention in pigeons and comparing it to humans.
    • The study highlights that attention, while adaptive, has inherent limitations like change blindness with real-world consequences.
