EDUCATIONAL PSYCHOLOGY REFLECTION FOR ACTION Canadian Edition O’Donnell, D’Amico, Schmid, Reeve, Smith CHAPTER 7 Cognitive Theories of Learning Chapter 7 Cognitive Theories of Learning • Themes of the chapter – The relationship between the individual and the environment is the key focus of cognitive theories of learning – Cognitive and constructivist theories of learning are related – Information processing descriptions of memory and storage of information Educational Psychology, Canadian Edition Guiding Questions • How do cognitive and constructivist theories of learning differ? • What are attention, perception, and working memory important for learning? • How is knowledge represented? • What are the different kinds of long-term memory? • How is encoding related to retrieval? • Why and how do we categorize? • How can teachers promote complex cognition? • How can teachers apply cognitive theories of learning in working with diverse students and students with special needs? Educational Psychology, Canadian Edition Cognitive and Constructivist Theories of Learning • Cognitive approach to learning – explores how individual differences in knowledge and experience influence the way we interpret the environment what we learn from that interaction • Knowledge is constructed by the learner and affected by the learner’s prior experiences Educational Psychology, Canadian Edition Constructivism • Exogenous – constructed knowledge that mirrors information in the environment • Endogenous – construction of new knowledge structures from existing structures rather than from the environment • Dialectical – knowledge lies in continual interaction between the individual and the environment Educational Psychology, Canadian Edition Information-Processing Model – Endogenous Constructivism • The learner develops internal representations of the external world • Perceptual and attentional processes limit the amount of information that is available Educational Psychology, Canadian Edition The Information-Processing Model • Limited capacity of various components of the memory system • Information processed in working memory • Information then transferred to long-term memory for later retrieval Educational Psychology, Canadian Edition The Information-Processing Model • Sensory memory – brief memories associated with various senses • Short-term memory – a temporary memory storage • Long-term memory – storage for indefinite periods of time Educational Psychology, Canadian Edition Perception • The meaning attached to sensory information – – Recognizing objects Objects recognition relies on form Educational Psychology, Canadian Edition Recognizing Objects • Feature analysis – identifying the component features of objects and building a representation of the object from them • Bottom-up analysis – a process in which a stimulus is analyzed into it components, then assembled into a recognizable pattern, also known as feature analysis • Top-down processing – a type of perception in which a person uses what he or she knows about a situation to recognize patterns Educational Psychology, Canadian Edition Object Recognition Relies on Form • Figure-ground – the ground is always seen as farther than the figure • Proximity – objects that are physically close together are grouped together • Continuity – objects that continue a pattern are grouped together • Closure – the tendency to see a finished unit • Similarity – similar objects are grouped together Educational Psychology, Canadian Edition Attention • Attention involves simultaneous experiences • It is selective, withdrawing from some objects and focusing on others • Lack of attention is characterized by confusion and diffusion Educational Psychology, Canadian Edition Theories of Attention • Filter theory – attention compared to a filter; sensory information processed, but quickly reaches a bottleneck; an all-or-none phenomenon • Attenuation model – attention to one source of information is reduced when one pays attention to another source • Capacity model – limited resource, similar to a reservoir that can be filled up or emptied Educational Psychology, Canadian Edition Your Turn • What are some ways that a Grade 4 teacher can help his students pay attention to his lesson? Educational Psychology, Canadian Edition Automaticity and Controlled Processes • Automaticity – the ability to perform a task without having to think much about it • Controlled processes – cognitive processes that require conscious attention Educational Psychology, Canadian Edition Sensory Memory • Iconic memory – memory for visual information • Echoic memory – memory for auditory information Educational Psychology, Canadian Edition Phenomena Associated with ShortTerm Memory • Serial position effect – fact that the likelihood of information being recalled varies according to its position in a list • Memory is better for some positions – Primacy – things at the beginning of the list – Recency – things at the end of the list • Unattended speech effect – verbal information in the environment has automatic access to the phonological loop and can interfere with cognitive processing Educational Psychology, Canadian Edition Short Term/Working Memory • • • • • • Capacity: Duration: Contents: Strategies: Forgetting: Other Features: Limited, 5- 9 bits of info Brief, < 20 seconds Visual, verbal Rehearsal, Chunking Decay, Interference Serial Position, Unattended speech effect Educational Psychology, Canadian Edition Keeping Information in Short-Term Memory • Maintenance rehearsal – cognitive process in which information in working memory is repeated to oneself frequently • Elaborative rehearsal – way of remembering information by connecting it to something that is already well known • Chunking – grouping of bits of data into larger, meaningful units Educational Psychology, Canadian Edition Information Lost from Short-Term Memory • Decay – loss of memories because information is not used • Interference – loss or deficiency of memories because of the presence of other information Educational Psychology, Canadian Edition Baddeley: Working Memory • Limited but active memory system • Differs from short-term memory in that it has storage and manipulation functions • Central processor or executive is guided by the goals of the individual – Monitors and executes current plan, such as attention, thinking, judging, and decision making Educational Psychology, Canadian Edition Possible Memory Difficulties of Children with Special Needs • They may exceed their working memory’s capacity • Constant interruption can produce interference effects • Difficulty writing because of limited working memory capacity • Deficits in working memory • One strategy: multiple modalities i.e., appeal to multiple senses Educational Psychology, Canadian Edition Long-Term Memory Types of long-term memory: • Episodic memory – long-term memory of particular places and event in a person’s life • Semantic memory – memory for meaning; the memory of verbal information or declarative knowledge i.e., knowledge of what or of facts Educational Psychology, Canadian Edition Long-Term Memory Brain Processes and Memory • Several structures in the medial temporal lobes of the brain are important for memory • Areas of the medial temporal lobe related to memory include: – Amygdala – Hippocampus – Rhinal cortex Educational Psychology, Canadian Edition Long-Term Memory Semantic Memory • Declarative knowledge – factual knowledge that can be expressed through verbal exchange, books, Braille, or sign language; know that something is true – Declarative memory – memory for abstract information – Procedural memory – memory for how to do things Educational Psychology, Canadian Edition Long-Term Memory Semantic Memory • The basic unit of a semantic network is a proposition, the smallest unit of meaning that can be verified as true or false and involves linking two concepts by a relationship Educational Psychology, Canadian Edition Your Turn • Describe the steps a teacher can take to help students store the information from a lesson in long-term memory Educational Psychology, Canadian Edition Long-Term Memory • Images – representations of objects that are not present and are thought to be stored in piecemeal fashion in long-term memory Educational Psychology, Canadian Edition Long-Term Memory Propositional network • Set of interconnected pieces of information that contains knowledge for the long term – Schema – the basic structure for organizing information – Script – a schema for the sequence of events in common events, such as ordering food at a fast-food restaurant • Story grammar – a type of script, typical structure of a category of stories Educational Psychology, Canadian Edition Long-Term Memory Levels of processing • A theory that asserts that recall of information is based on how deeply it is processed Educational Psychology, Canadian Edition Encoding, Retrieval, and Forgetting • Encoding – the taking in of information • Retrieval – probability that information will be retrieved depends on quality of encoding Educational Psychology, Canadian Edition Types of Knowledge • Procedural knowledge – knowledge about how to perform tasks • Conditional knowledge – knowledge that guides a person in using declarative an procedural knowledge Educational Psychology, Canadian Edition Organization, Practice, and Elaboration Organized material is easier to learn than disorganized material • Distributed practice – practice that is interspersed by unequal intervals • Massed practice – intense practice for a single period of time (cramming) • Elaboration – a process through which we add and extend meaning by connecting new information to existing knowledge in long-term memory Educational Psychology, Canadian Edition Mnemonic Strategies • Strategies for remembering nonmeaningful information by making it meaningful – Acronyms – Keyword strategy – Pictorial mnemonics – Method of loci – Pegword mnemonics Educational Psychology, Canadian Edition Imagery and Visual-Learning Strategies • Dual-coding theory – images and words are represented differently;
