The split-attention effect is a learning effect inherent within some poorly designed instructional materials. It is apparent when the same modality (e.g. visual) is used for various types of information within the same display. Users must split their attention between the materials, for example, an image and text, to understand the information being conveyed. The split-attention effect can occur physically through visual and auditory splits and temporally when time distances two pieces of information that should be connected. [1]
Consider the graphic below from Tarmizi and Sweller. [2] They used these graphics to compare the learning that takes place given split attention conditions. Each is a possibility of how one might arrange graphical material within a lesson. Ward and Sweller advise instructional designers to be careful when they direct a learner's attention. [3] In several studies and experiments, Sweller and his associates found that learners had difficulty following some worked examples with diagrams separated from formulas, whereas learners using integrated diagrams were better able to process that information, and significantly improved their performance relative to their peers. [3] [4] [5] [6] [7]
The split-attention effect is not limited to geometry. Chandler and Sweller found that this effect extends to a variety of other disciplines, due to it being a limitation in human information processing. [4] This is the result of high visual cognitive load due to poor instructional design.
The figure on the left side of the image produces the split-attention effect, while the figure on the right enhances learning because it guides the learner's attention through the worked example. Unincorporated visual displays of information, such as the image above, can be distracting and confusing for the user, aside from producing the split-attention effect. [8] The split-attention effect is an important form of extraneous cognitive load that instructional material designers should avoid. [7]
Chandler and Sweller found through empirical study that the integration of text and diagrams reduces cognitive load and facilitates learning. [5] They found that the split-attention effect is evident when learners are required to split their attention between different sources of information (e.g., text and diagrams). A study done in 1979 by Egan and Schwartz revealed the importance of chunking in the recall process of symbolic images. [9] Chunking has been proven to be a successful aid in long-term memory and image recall. [10] Egan and Schwartz's study also suggests that chunking cannot adequately be implemented when the information and an image produce a split-attention effect. [9]
Split attention is important evidence of the cognitive load theory as it demonstrates that the working memory load of instructional materials is important in the design of instructional materials. Chandler and Sweller also found that students viewing integrated instruction spent less time processing the materials and outperformed students in the split attention condition. [5] Pociask and Morrison found in another study that integrated materials resulted in higher test scores and reduces extraneous cognitive load. [7]
Deaf and hard of hearing students often experience and struggle with the visual split-attention effect. Because deaf and hard of hearing students need to focus their attention on the teacher or an interpreter, the student is forced to divide their attention between the instructor and the learning material. [11] Deaf and hard of hearing students are most likely to have the best experience in class and ease the effects of a split attention if they have a complete view of the classroom. [12] The split-attention effect not only affects a deaf or hard of hearing individual's schoolwork. It affects their daily life as well because visual input is their main source of communication and information about the world around them.
An auditory split-attention effect can occur when audio material and visual material result in an additional cognitive load. [13] Moreno and Mayer found evidence for auditory split attention when they tested learners with both ambient environmental sounds and music as they learned from instructional materials. [14] Animation is processed in a visual channel but must be converted to the auditory channel. The extraneous cognitive load imposed by music or environmental sounds were not conducive to learning.
There have been propositions to eliminate the term "split-attention effect" and replace it with "spatial contiguity". These phenomena are very similar, however, split-attention conditions do not need to be present in order for the spatial contiguity principle to take effect. [1] The spatial contiguity principle is the idea that corresponding information is easier to learn in a multimedia format when presented close together rather than separate or farther apart. [15]
The redundancy effect has also been linked to the split-attention effect. The redundancy effect is the idea that instruction materials that are not integrated properly produce and present information in a repetitive way, making it more likely to process unnecessary information and increase cognitive load. [16]
Learning theory describes how students receive, process, and retain knowledge during learning. Cognitive, emotional, and environmental influences, as well as prior experience, all play a part in how understanding, or a worldview, is acquired or changed and knowledge and skills retained.
Instructional scaffolding is the support given to a student by an instructor throughout the learning process. This support is specifically tailored to each student; this instructional approach allows students to experience student-centered learning, which tends to facilitate more efficient learning than teacher-centered learning. This learning process promotes a deeper level of learning than many other common teaching strategies.
The Atkinson–Shiffrin model is a model of memory proposed in 1968 by Richard Atkinson and Richard Shiffrin. The model asserts that human memory has three separate components:
In cognitive psychology, chunking is a process by which small individual pieces of a set of information are bound together to create a meaningful whole later on in memory. The chunks, by which the information is grouped, are meant to improve short-term retention of the material, thus bypassing the limited capacity of working memory and allowing the working memory to be more efficient. A chunk is a collection of basic units that are strongly associated with one another, and have been grouped together and stored in a person's memory. These chunks can be retrieved easily due to their coherent grouping. It is believed that individuals create higher-order cognitive representations of the items within the chunk. The items are more easily remembered as a group than as the individual items themselves. These chunks can be highly subjective because they rely on an individual's perceptions and past experiences, which are linked to the information set. The size of the chunks generally ranges from two to six items but often differs based on language and culture.
Learning styles refer to a range of theories that aim to account for differences in individuals' learning. Although there is ample evidence that individuals express personal preferences on how they prefer to receive information, few studies have found validity in using learning styles in education. Many theories share the proposition that humans can be classified according to their "style" of learning, but differ on how the proposed styles should be defined, categorized and assessed. A common concept is that individuals differ in how they learn.
Baddeley's model of working memory is a model of human memory proposed by Alan Baddeley and Graham Hitch in 1974, in an attempt to present a more accurate model of primary memory. Working memory splits primary memory into multiple components, rather than considering it to be a single, unified construct.
Constructivism in education is a theory that suggests that learners do not passively acquire knowledge through direct instruction. Instead, they construct their understanding through experiences and social interaction, integrating new information with their existing knowledge. This theory originates from Swiss developmental psychologist Jean Piaget's theory of cognitive development.
In cognitive psychology, cognitive load refers to the amount of working memory resources used. However, it is essential to distinguish it from the actual construct of Cognitive Load (CL) or Mental Workload (MWL), which is studied widely in many disciplines. According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: intrinsic cognitive load is the effort associated with a specific topic; extraneous cognitive load refers to the way information or tasks are presented to a learner; and germane cognitive load refers to the work put into creating a permanent store of knowledge. However, over the years, the additivity of these types of cognitive load has been investigated and questioned. Now it is believed that they circularly influence each other.
Visual learning is a learning style among the learning styles of Neil Fleming's VARK model in which information is presented to a learner in a visual format. Visual learners can utilize graphs, charts, maps, diagrams, and other forms of visual stimulation to effectively interpret information. The Fleming VARK model also includes Kinesthetic Learning and Auditory learning. There is no evidence that providing visual materials to students identified as having a visual style improves learning.
Information processing theory is the approach to the study of cognitive development evolved out of the American experimental tradition in psychology. Developmental psychologists who adopt the information processing perspective account for mental development in terms of maturational changes in basic components of a child's mind. The theory is based on the idea that humans process the information they receive, rather than merely responding to stimuli. This perspective uses an analogy to consider how the mind works like a computer. In this way, the mind functions like a biological computer responsible for analyzing information from the environment. According to the standard information-processing model for mental development, the mind's machinery includes attention mechanisms for bringing information in, working memory for actively manipulating information, and long-term memory for passively holding information so that it can be used in the future. This theory addresses how as children grow, their brains likewise mature, leading to advances in their ability to process and respond to the information they received through their senses. The theory emphasizes a continuous pattern of development, in contrast with cognitive-developmental theorists such as Jean Piaget's theory of cognitive development that thought development occurs in stages at a time.
Discovery learning is a technique of inquiry-based learning and is considered a constructivist based approach to education. It is also referred to as problem-based learning, experiential learning and 21st century learning. It is supported by the work of learning theorists and psychologists Jean Piaget, Jerome Bruner, and Seymour Papert.
E-learning theory describes the cognitive science principles of effective multimedia learning using electronic educational technology.
The worked-example effect is a learning effect predicted by cognitive load theory. Specifically, it refers to improved learning observed when worked examples are used as part of instruction, compared to other instructional techniques such as problem-solving and discovery learning. According to Sweller: "The worked example effect is the best known and most widely studied of the cognitive load effects".
The modality effect is a term used in experimental psychology, most often in the fields dealing with memory and learning, to refer to how learner performance depends on the presentation mode of studied items.
Perceptual learning is learning better perception skills such as differentiating two musical tones from one another or categorizations of spatial and temporal patterns relevant to real-world expertise. Examples of this may include reading, seeing relations among chess pieces, and knowing whether or not an X-ray image shows a tumor.
The expertise reversal effect refers to the reversal of the effectiveness of instructional techniques on learners with differing levels of prior knowledge. The primary recommendation that stems from the expertise reversal effect is that instructional design methods need to be adjusted as learners acquire more knowledge in a specific domain. Expertise is described as "the ability to perform fluently in a specific class of tasks."
A pedagogical agent is a concept borrowed from computer science and artificial intelligence and applied to education, usually as part of an intelligent tutoring system (ITS). It is a simulated human-like interface between the learner and the content, in an educational environment. A pedagogical agent is designed to model the type of interactions between a student and another person. Mabanza and de Wet define it as "a character enacted by a computer that interacts with the user in a socially engaging manner". A pedagogical agent can be assigned different roles in the learning environment, such as tutor or co-learner, depending on the desired purpose of the agent. "A tutor agent plays the role of a teacher, while a co-learner agent plays the role of a learning companion".
Crossmodal attention refers to the distribution of attention to different senses. Attention is the cognitive process of selectively emphasizing and ignoring sensory stimuli. According to the crossmodal attention perspective, attention often occurs simultaneously through multiple sensory modalities. These modalities process information from the different sensory fields, such as: visual, auditory, spatial, and tactile. While each of these is designed to process a specific type of sensory information, there is considerable overlap between them which has led researchers to question whether attention is modality-specific or the result of shared "cross-modal" resources. Cross-modal attention is considered to be the overlap between modalities that can both enhance and limit attentional processing. The most common example given of crossmodal attention is the Cocktail Party Effect, which is when a person is able to focus and attend to one important stimulus instead of other less important stimuli. This phenomenon allows deeper levels of processing to occur for one stimulus while others are then ignored.
Seductive details are often used in textbooks, lectures, slideshows, and other forms of educational content to make a course more interesting or interactive. Seductive details can take the form of text, animations, photos, illustrations, sounds or music and are by definition: (1) interesting and (2) not directed toward the learning objectives of a lesson. John Dewey, in 1913, first referred to this as "fictitious inducements to attention." While illustrated text can enhance comprehension, illustrations that are not relevant can lead to poor learning outcomes. Since the late 1980s, many studies in the field of educational psychology have shown that the addition of seductive details results in poorer retention of information and transfer of learning. Thalheimer conducted a meta-analysis that found, overall, a negative impact for the inclusion of seductive details such as text, photos or illustrations, and sounds or music in learning content. More recently, a 2020 paper found a similar effect for decorative animations This reduction to learning is called the seductive details effect. There have been criticisms of this theory. Critics argue that seductive details do not always impede understanding and that seductive details can sometimes be motivating for learners.
Multisensory learning is the assumption that individuals learn better if they are taught using more than one sense (modality). The senses usually employed in multisensory learning are visual, auditory, kinesthetic, and tactile – VAKT. Other senses might include smell, taste and balance.
