Decision Making: Traditional Method01:14

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...
The Stanford Prison Experiment03:20

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.
Decision Making: P-value Method01:09

Decision Making: P-value Method

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
Surveys02:16

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
Archival Research01:40

Archival Research

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...
Framing Effects03:26

Framing Effects

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in different ways based on the...

Area of Science:

  • Criminal Justice
  • Legal Research
  • Criminology

Background:

  • Sentencing decisions are crucial for achieving justice goals like punishment, rehabilitation, deterrence, incapacitation, and victim reparation.
  • Ensuring transparency, consistency, and justification in sentencing requires a deep understanding of its determinants.
  • Research on sentencing must be methodologically sound and feasible within resource constraints.

Purpose of the Study:

  • To investigate the factors influencing judicial sentencing decisions.
  • To present and compare three distinct methodological approaches for studying sentencing determinants.
  • To inform the development of more effective and equitable sentencing practices.

Main Methods:

  • Multilevel analysis of existing sentencing data.
  • Sampling and data collection from sentenced court case files.
  • Experimental designs where sentencers evaluate hypothetical cases.

Main Results:

  • Each methodological approach offers unique strengths and weaknesses for analyzing sentencing factors.
  • Multilevel analysis provides insights into aggregate patterns.
  • Case file analysis allows for detailed examination, while experimental designs assess decision-making processes.

Conclusions:

  • The choice of methodology significantly impacts the understanding of sentencing determinants.
  • A combination of approaches may offer a more comprehensive view of sentencing influences.
  • Methodological rigor is essential for advancing knowledge in sentencing research and practice.
