David P Ausubel
To Ausubel, meaning was aphenomenon of consciousness and not of behavior. The external world acquiresmeaning when it is converted into the "content of consciousness." Hebelieved that a signifier (ie. word) has a meaning when its effect upon thelearner is equivalent to the effect of the object it signifies.
Bruner believedwhen there is "...some form of representational equivalence betweenlanguage (or symbols) and mental content," then there is meaning. Hebelieved there are two processes involved in cognitive learning: the receptionprocess and the discovery process. What he termed receptionprocesses are almost exclusively used in meaningful verbal learning. Concept formation and problem solving are more likely, according to Ausubel, toinvlove discovery processes.
Ausubel felt discovery learning techniques are often uneconomical,inefficient, and ineffective. He felt most school learning is verbal learning(receptive learning).
Subsequent research has shown that verbal learning is most effective forrapid learning and retention and that discovery learning is most effective infacilitating transfer.
Jerome Bruner
Bruner maintained that people interpret the world in terms of similaritiesand differences which are detected among objects and events. Objects that areviewed as similar are placed in the same category. The major variable in histheory of learning is the coding system into which the learner organizes thesecategories. The act of categorizing is assumed to be involved in informationprocessing and decision making.
Bruner's theory of cognitive learning theory emphasizes the formation ofthese coding systems He believed that the systems facilitate transfer, enhanceretention and increase problem solving and motivation. He advocated thediscovery oriented learning methods in schools which he believed helped studentsdiscover the relationships between categories.
Memory
Memories are not like photoalbums because memories are rarely exact copies of earlier experiences. Whatyou remember is influenced by many factors, some operating at the time of theoriginal encoding of information, others operating during storage, and still others operating atthe time of recall.
Memories can be affected by physical health, attention,emotion, prejudice, and many other conditions.
There are three types of memory:sensory, short-term, and long-term (Zimbardo, 1993).
- Sensory memory- preserves fleeting impressions of sensorystimuli-sights, sounds, smells, and textures for only a fraction of a second.
- Short-Term memory- includes recollections for what we have recentlyperceived, such as limited information, lasts only up to twenty seconds unlessspecial attention is paid to it or is reinstated for rehearsal. Information inshort term memory is limited to seven discrete units (plus or minus 2)
- Long-Term memory-preserves information for retrieval at any time. The information may be stored for an entire life time and constitutes ourknowledge about the world. Long term memory is considered to be unlimited induration and capacity.
Psycholinguistics
How weacquire and process knowledge depends to a great extent on the nature of thatknowledge. Psycholcinguistics have found that speech perception andcomprehension involves deductive processing as well as inductive processing.
Deductive processing as it relates to linguistics is the use of grammatical and contextualinformation where it originates in the brain and influences selection,organzation or interpretion of sensory data. For example, when subjects hearrecorded sentences in which some part of the signal is removed and a cough issubstituted, they "hear" the sentence without a missing phoneme andin fact are unable to say which phonemic segment the cough replaced.
Inductive processing as used by linguists is the use of sensory information of thesignal. In speech understanding, we use stored semantic, lexicial and syntacticinformation as well as the sensory information in the signal itself. Subjectsmake fewer errors identifying words when the words occur in sentences than whenthey are presented in isolation. They do better if the words occur ingrammatical, meaningful sentences as opposed to grammatical, unmeaningfulsentences (Fromkin and Rodman, 1991).
Perception/Comprehension
Our ability to perceive and sense contributes to our uniquenesson a further dimension: we have a conscious awareness of ourselves and anability to go beyond that experience, extending the limits of our consciousness.Perception also refers to later processess that organize and interpret information in asensory image as having been produced by the properties of objects in theexternal, three dimensional word.
The first stage in the comprehension process is the perception of the speechsignal, an acoustic signal produced the speaker. This includes the position ofthe tongue, lips, velum, the state of the vocal cords, and the airstreammechanisms. The intrepretation of these sounds is necessary in order to learnthe language, therefore, understand the content (Fromkin and Rodman, 1991).
