Relationship Formation02:12

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
Motivational Bias01:25

Motivational Bias

Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
Halo Effect01:27

Halo Effect

The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...
Multiple Comparison Tests01:13

Multiple Comparison Tests

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Observational Studies01:11

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One example of...

Area of Science:

  • Social Sciences
  • Psychology
  • Education
  • Organizational Behavior

Background:

  • Mentoring research traditionally occurs in isolated disciplinary silos.
  • Focus has often been on specific types of mentoring relationships.
  • A comprehensive quantitative review across major mentoring domains is lacking.

Purpose of the Study:

  • To quantitatively review mentoring research in youth, academic, and workplace settings.
  • To determine the overall effect size of mentoring on protégé outcomes.
  • To explore variations in mentoring's impact based on relationship type.

Main Methods:

  • Quantitative meta-analysis of existing mentoring studies.
  • Inclusion of research from youth, academic, and workplace mentoring contexts.
  • Analysis of effect sizes for diverse protégé outcomes.

Main Results:

  • Mentoring is linked to numerous positive outcomes (behavioral, attitudinal, health, relational, motivational, career).
  • The overall effect size for mentoring is generally small.
  • Academic and workplace mentoring demonstrated larger effect sizes compared to youth mentoring.

Conclusions:

  • Mentoring provides broad benefits for protégés across different contexts.
  • The type of mentoring relationship influences the magnitude of its effects.
  • Findings inform future research, theory development, and practical applications in mentoring.
