experiment copes with the potential effects of extraneous variables by using random assignment to experimental conditions and sometimes also by incorporating direct control and/or blocking into the design of the experiment. Each of these strategies—random assignment‚ direct control‚ and blocking—is described as follows; A researcher can directly control some extraneous variables. In the calculus test example‚ the textbook used is an extraneous variable because part of the differences in test results

Extraneous Variables There are many extraneous factors and situations that could affect our research; such as‚ biological factors‚ family issues‚ marital problems‚ transportation‚ insurance issues‚ how often participants choose to show up to their therapy session‚ etc. While extraneous factors and situations are bound to happen‚ we can not account for all of them as they will be happening as the research progresses and are out of our control. Qualitative Design We will observe two themes throughout

The following attempts in which the researcher will take care of these extraneous variables is discussed below; Control of Hawthorne Effect: This happens when student performance are affected because the students

Stroop effect and reading process Abstract This study evaluated the effect of congruency of color ink and color name on reading process. The 30 participants of the experiment were assigned to sets 1(a condition wherein congruent color names and ink color were presented first before the incongruent set of words‚ and 2 (reverse of set 1) by random selection. Participants were called in the laboratory two at a time‚ one of them from set 1 participants and the other from set

The Effect of Stroop Level of Interference on the Reaction Time Queens College‚ CUNY Abstract The aim of this study was to assess whether Stroop interference did indeed replicate with modern day students. Undergraduate students sample was obtained consisting of 12 females and 6 males‚ who are students in experimental psychology class. The independent variable was the condition of the stimuli with 3 levels (low‚ medium and high interference conditions). The dependable

incongruence and interference: A Stroop Recreation Australian College of Applied Psychology Abstract The original Stroop Experiment performed by J.R Stroop in 1935 opened the field for experiments to research interference and its effects‚ causes and implications. This study looks at the Stroop findings in modern setting to get a new perspective on the causes of interference. 41 first year uni students were asked to participate in a direct recreation of the original Stroop Experiment‚ their results

a desired conclusion or response. Interference’s effect was the main source of study behind the Stroop task (Stroop‚ 1935). The origins of the Stroop task came from the titular researcher determining to what end can contrasting stimuli‚ in this case the name of a color and the color of ink used for that word‚ interfere with one another (Stroop‚ 1935). This interference was due to automaticity (Stroop‚ 1935). Automaticity is the cognitive function of reacting to a stimulus so quickly due to the small

In this experiment‚ John Stroop studied and compared subjects reading a list of words that were printed in black and had the same group of subjects read the same list of words in incongruent colors. Stroop didn’t find very

I. INTRODUCTION The Stroop effect (sometimes called the Stroop test) is an outcome of our mental (attentional) vitality and flexibility. The effect is related to the ability of most people to read words more quickly and automatically than they can name colors. John Ridley Stroop first reported this effect in his Ph.D. dissertation published in 1935. Current research on the Stroop effect emphasizes the interference that automatic processing of words has on the more mentally effortful task of just
