Cause and Effect01:53

Cause and Effect

10.9K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Regression Toward the Mean01:52

Regression Toward the Mean

6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Statistical Significance01:50

Statistical Significance

20.1K
Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...

Naturalistic Observations

15.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Hindsight Biases01:12

Hindsight Biases

3.4K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Blind Procedures02:07

Blind Procedures

10.6K
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...

Summary
This summary is machine-generated.

Inattentional blindness, the failure to notice unexpected stimuli, is more likely to occur in statistically improbable scenes compared to probable ones. This study investigated scene regularity and its impact on visual attention.

Area of Science:

  • Cognitive Psychology
  • Visual Perception
  • Attention Studies

Background:

  • Observers often miss statistical irregularities in real-world scenes.
  • Inattentional blindness rates are higher for improbable stimuli.
  • Direct comparisons of noticing rates for probable versus improbable scenes are lacking.

Purpose of the Study:

  • To investigate if inattentional blindness likelihood differs between statistically probable and improbable scenes.
  • To determine if scene regularity influences the perception of unexpected stimuli.

Main Methods:

  • Two large-scale experiments were conducted.
  • Participants were presented with either a probable or an improbable scene during a critical trial.
  • Rates of inattentional blindness were compared between the two groups.

Main Results:

  • Higher rates of inattentional blindness were observed in participants viewing improbable scenes.
  • Participants were less likely to notice unexpected stimuli in statistically irregular scenes.

Conclusions:

  • The statistical regularity of a scene significantly impacts the likelihood of experiencing inattentional blindness.
  • Improbable scenes increase the risk of missing unexpected visual information.
