Research Methods: Biases in Research - Acquiescence & Sponshorship

Welcome to the next episode in my mini-series on biases in research! Today we talk about two (as to me, related) biases: Acquiescence bias, i.e. a tendency to agree with the interviewer; and the Sponsor bias, i.e. the (unconscious) tendency to give answers, the respondent assume the sponsor of the survey would like to hear.

Enjoy and leave your comments!

Research Methods: Biases in Research - Habituation

Have you ever noticed when answering a series of questions, all relating to the same topic, that your answers correlate? Actually, they should as usually you are asked about different aspects of the same latent constructs. Yet, sometimes we tend to set the mark without a specific intent - you just mark everything slightly to the right side (or to the left one). We do not go too deep into the aspects and answer with some degree of automaticity. 

Not sure? Just our one reversely coded item and you will notice that even reversely coded it does not show a full negative correlation. At least in my experience, it is the case. More on the issue in this episode. Enjoy!

Research Methods: Biases in Research - Social Desirability

Welcome to my new mini-series on biases in research. Today I talk about one of the "Respondent biases". In particular, I talk about social desirability. First, I explain the issue. Then, I give you some hints on how to test it. Later, I give you advice on how to avoid social desirability. Some examples follow.

Good luck with your research!

Research Methods: Research Models - Complex Models

Morning!

 

And here comes our final episode in a mini-series on research models. Please let me know if you have a specific question which I should add to this mini-series. 

In this episode, I talk about more complex models and an unlimited number of combinations of moderating and meditation effects you can add to your model. Yet, my recommendation is: remain as simple as possible but not simpler.

Good luck!

Faithfully,

Research Methods: Research Models - A Moderated Moderation Model

Hello everyone

 

After a short break, I continue with the next episode in the mini-series on research models. Today, I talk about the moderated moderation, i.e. model incorporating several conditions shifting your main effect between the independent and dependent variables. 

 

Enjoy, subscribe, and share!

Research Methods: Research Models - A Double Mediation Model

The double mediation model is a more complex version of the simple mediation model. In this model, you ask yourself the question "why?" twice. The double mediation model gives deeper into the nature of the hypothesised relationship. Yet, it requires also a deeper theoretical analysis as well as more complex statistical calculations.

Enjoy this episode with a simple example!

Research Methods: Research Models - A Moderation Model

As a researcher, have you ever asked yourself a question "Under which conditions is the hypothesised relationship weaker/stronger?". If yes, then you have already dealt with moderation. A moderator is a variable that shifts the relationship between the independent and dependent variables. Enjoy my example with ice cream and the level of happiness!

Research Methods: Research Models - A Mediation Model

A mediation model gives a researcher an answer to the question "Why?". If you have a relationship between two variables and assume that this relationship happens because of the third variable, you talk about the mediation model. We also call the mediator an explanatory variable (as it explains "why" the hypothesised relationship occurs).

Enjoy this episode and the simple example it contains!

Research Methods: Research Models - A Direct Effects Model

Welcome! Today we talk about the simplest form of a research model - a direct effects model. Using a simple observation (Ice cream makes people happy), we try to develop a research model to test for this simple direct effect. More complex models will follow ;)

Enjoy and good luck with your research!

Management Research: Psychological Distance and Associated Types of Smiles

In this episode, I present results from my research with a colleague and friend of mine - Professor Florian Dost. We investigated the level of psychological distance associated with Duchenne and non-Duchenne smiles. 

The results of the study were published in the open science format, so feel free to access:
