Summary
This study dynamically assessed behavioral resurgence in pigeons, finding that signaled extinction probes increased the recurrence of previously learned behaviors. This offers new methods for studying treatment relapse.
Area of Science:
- Behavioral psychology
- Animal behavior studies
Background:
- Resurgence, the return of extinguished behavior, offers insights into treatment relapse.
- Traditional resurgence studies use lengthy, multi-phase procedures.
- A dynamic assessment method is needed to better understand resurgence.
Purpose of the Study:
- To dynamically assess resurgence in pigeons throughout ongoing training.
- To investigate the role of signaled versus unsignaled extinction in resurgence.
- To test a stimulus-control model of resurgence.
Main Methods:
- Used a 50-s free-operant psychophysical procedure with pigeons, alternating reinforcement for target and alternative responses.
- Introduced 100-s extinction probes (signaled and unsignaled) to elicit resurgence.
- Applied an extended stimulus-control model to analyze data.
Main Results:
- Pigeons showed resurgence of target responding during extinction probes.
- Resurgence was greater and/or occurred sooner during signaled extinction probes.
- A stimulus-control model accurately described the observed resurgence patterns.
Conclusions:
- Dynamic assessment of resurgence is feasible and reveals key variables.
- Discriminating transitions to extinction, especially when signaled, influences resurgence.
- The findings support a model of resurgence based on reinforcer generalization.

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

01:12Quantitative Analysis
1.7K
Quantitative analysis is a technique for measuring the amount of specific constituents in a sample. When the sample's composition is unknown, qualitative analysis is performed first to identify its components, which ensures that the correct substances are measured during the quantitative phase.
In quantitative analysis, two key measurements are made: the sample quantity and a property proportional to the amount of the analyte (the substance being analyzed). This forms the basis of the...

16.8K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.

The vertical distance between the actual value of y and the estimated value of y. In other words, it measures the vertical distance between the actual data point and the predicted point on the line
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.

02:04Conservation of Small Populations
17.6K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

13.7K
The critical region, critical value, and significance level are interdependent concepts crucial in hypothesis testing.
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
