Change Blindness

Change Blindness

Introduction

The core purpose of this paper is to enlighten the concept of change blindness in a holistic manner. The paper is based on an experiment through which the sample of the study has been used for extracting substantial data for analysis. Change blindness has attained significant attention of the researchers and scientists since the last decade. Change blindness represents the visual status of an individual in which the/she is unable to differentiate the changes that are made in certain objects. The objects can be any entity of a visual scene that has encountered significant changes; however, the individual is not able to notice or observe the changes that have been made. This is called change blindness as an individual is blind to notice any change encountered by the object. This paper corresponds to experimental research as an experiment was conducted in order to validate the findings of the study. Nonetheless, the paper uses the data gathered from the primary source of data collection (sample size) in order to execute statistical analysis on the data.

Aim of the Study

The aim of this experiment was to test the effects of change blindness in 4 different conditions.

Study Hypothesis

Hypothesis 1: There is not significant effect revealed by 4 different conditions of change blindness on the sample.

Hypothesis 2: There is a significant effect revealed by 4 different conditions of change blindness on the sample.

Literature

Change blindness refers to inability to retain and recall past visual experiences that are initially encoded, stored and retrieved in a meaningful way. In relation to change blindness: Sensory or 'iconic' memory is relevant. The first stage of memory refers to diverse categories of sensory information (especially visual) held in a brief sensory register (50 - 500msecs). This information is lost if consolidated in working or short-term memory (Mitroff, Simons & Levin, 2004). Over-writing of iconic memory trace denotes that verbal labels are used to remember what objects are in the scene (e.g. 'green door on left') and this is encoded into short-term memory, when a new scene is presented, people will have no record of all of a large number of objects in the original scene (Landman, Spekreijse & Lamme, 2004).

Change blindness across saccadic eye movements (Simulation) represents to an aspect of eye movements that might account for change blindness is the existence of motion transients across the retina. In a sense, the target change cannot be identified because the eye is processing change signals from every location before and after the eye movement (Smith & Schenk, 2008). If these global transients effectively mask the ability to localize an individual transient or change, then any display that creates global transients should make change detection difficult (Cole & Liversedge, 2006).

Method of the Study

Participants

This study incorporates 155 participants that are the students of undergraduate psychology taking a course in biopsychology. The participants were required to take the experiment in tutorials. The participants consisted of 111 females (72.1) 43 males (27.9) one person did not record their gender.
