Subject Pool
A subject pool is an established group of individuals who have formally agreed to be contacted about participating in research studies. In university settings, this typically consists of students enrolled in introductory psychology courses who sign up via an online system to participate in experiments to fulfill a course requirement.

Participant Recruitment for Pilot Tests
Match each participant recruitment method with its correct description.
A researcher studying cognitive aging visits a local senior center to invite residents to participate in a memory study. Which statement best explains why this activity is categorized as participant recruitment?
A researcher is planning a study on the social dynamics of local recreational sports teams. Arrange the following steps of the participant recruitment process in the most logical order.
In the process of participant recruitment, the specific method used to reach individuals—such as where an advertisement is placed—functions as a mechanism that filters which subset of the population of interest is represented in the study.
A researcher is designing a study on the social support networks of parents caring for children with chronic illnesses. To create an effective participant recruitment plan that ensures the population of interest is represented, which of the following strategies should be constructed?
A researcher is evaluating a recruitment plan that only uses personal appeals to members of a local hiking club to study 'general community fitness levels.' By concluding that this plan is insufficient because it excludes non-hikers and those with different physical abilities, the researcher is judging the strategy based on its failure to achieve _____.
The foundational process of finding and obtaining individuals to take part in a research study is known as participant _____.
A researcher is developing a new cognitive test and wants to run a pilot test to check for any software bugs. Since this is a pilot test, the researcher can recruit participants informally from among their own friends, family, and classmates.
Match each hypothetical research recruitment scenario with its corresponding recruitment method as described in the text.
Arrange the steps of the participant recruitment process in the logical sequence a researcher must follow from project inception to the execution of the main study.
Example of Convenience Sampling: Introductory Psychology Students
Subject Pool
What is the primary disadvantage of using a convenience sample in psychological research?
A researcher recruits participants for a study on stress by approaching students in her own introductory psychology class and asking for volunteers. She argues that because the class contains students from many different majors, the resulting sample adequately represents the broader population of young adults. Is her reasoning correct?
A team of researchers is using convenience sampling for various psychological studies. Match each specific sampling scenario with the primary limitation it creates for the study's generalizability.
A researcher is analyzing how a convenience sampling strategy might bias a study on 'Employee Burnout.' Arrange the following events in the logical sequence that demonstrates how this sampling method leads to a failure in generalizing findings to the entire organization.
Imagine you are developing a preliminary research plan to investigate the relationship between late-night study habits and daytime alertness in your peers. You have no budget for recruitment and must begin data collection within hours. Which of the following strategies would you construct to ensure your selection method follows the method of convenience sampling?
Convenience sampling is classified as a form of probability sampling because it selects individuals who are readily available to the researcher.
When evaluating a researcher's claim that findings from a study using only readily available volunteers apply to the general population, a critical reviewer would judge the conclusion as weak because the recruited group lacks _____.
A professor asks students to apply their knowledge of convenience sampling by correctly linking each term or real-world scenario to its accurate description in a research context. Match each item on the left to its correct description on the right.
A social psychologist studies conformity by recruiting participants exclusively by approaching shoppers at a single suburban mall on weekday mornings. A methodologist reviewing the study notes that weekday-morning mall visitors are disproportionately retired adults, stay-at-home caregivers, and part-time workers — groups that likely differ from the broader adult population in age, employment status, and daily social routines. Because participants were selected purely on the basis of availability rather than through any random process, the sample is _____ of the general adult population, which is the defining analytical limitation of convenience sampling.
A research team wants to study depression rates among first-generation college students nationwide. They are debating whether convenience sampling is an appropriate strategy. Arrange the following steps in the order a researcher should carry them out when critically evaluating whether convenience sampling is the right choice for this research goal.

To demonstrate your understanding of how subject pools function within a university research setting, match each concept with its corresponding role or definition.
A researcher concludes that a university subject pool is an inappropriate recruitment source for a study on the life satisfaction of middle-aged working professionals. In making this judgment, the researcher is evaluating the study's _____ validity and finding it insufficient for the specific research goal.
