PSY 3490 M Tutorial March 4/10
Person-Environment Interactions • B = f (P,E) Competence • Person’s capacity to function in 5 domains (biological health, sensory-perceptual functioning, motor and cognitive skills, ego strength) Environmental Press • Varying demands (physical, interpersonal, social) that environments place on an individual To have a good adaptation level, older adults need to lower the environmental press and increase competence
Stress and Coping Framework • Adaptation depends on one’s perceptions of environmental stress and their attempts to cope • Protective impact of social support systems • The Loss Continuum Concept • Aging as a progressive series of losses that reduces one’s social participation (e.g. loss of social roles, income, mobility) • Thus, home and neighborhood take on more importance
Long-Term Care Facilities • Chronic Care • In-patient, hospital setting providing high level of personal care and specialized treatments • Nursing Homes • Provide moderate to high levels of personal care • Assisted Living Faculties • Provide supportive living arrangements for people who need assistance • Adult Foster Care • House people who need assistance of ADL due to disabilities or chronic disorders
Social-Psychological Perspective • Importance of maintaining a sense of personal control in maintaining well-being • Five aspects of nursing homes fail to make residents feel competent and in control • Placement in nursing home, label of ‘nursing home resident’, staff’s care toward residents, physical aspects of environment, routine • In order to make a positive impact, increase level of control, have residents actively involved in creating their environment, and in decision making
Information-Processing Model • Information enters the system and is transformed, coded and stored in various ways • Sensory Memory • Earliest step in IP. Has a large capacity but is very short lived. • No age differences • Attentional Processes • Influenced by the capacity to direct and sustain attention • Age-related limitations impact attentional processes
Attention • Which information is processed beyond sensory memory is determined by attention • Selective Attention • Multiple sources of information are available for processing, but only a subset is relevant (e.g. driving) • Moving from large-capacity store, to a very small-capacity story (working memory) • age differences in ability to selectively attend to information • Due to greater difficulty in filtering out or inhibiting irrelevant information in older adults
Divided Attention • The ability to successfully perform more than one task at the same time • No differences found on easy tasks, but are found on complex tasks • No age differences when older adults are given extensive practice • Sustained Attention • The ability to sustain attention over long periods of time • Age related declines in vigilance performance, but not vigilance decrement
Main Conclusion for Research on Attention • Age differences are greatest when older adults perform complex tasks, especially more than one at a time….but why?
Speed of Processing • As people age, the speed with which one makes a response, decreases • older adults take longer to decide to make a response • As reaction time tasks become more complex, older adults become even slower (e.g. driving a car) • Minimizing age differences: • Experience/practice, exercise and fitness training increases blood circulation and neurological functioning
Language Processing • Involves interactions between sensory system and basic information-processing abilities • Language comprehension is usually not impaired before the age of 80 • Speech recognition and speech discrimination decline with age, although older adults use context to figure what was said
How is Information kept in Mind for Additional Processing? • Working Memory • Holding information in mind and using that information to solve a problem, make decisions, or learn new information • A limited capacity where only a few items can be processed at once • Declines in working memory related to • Declines in storage capacity • Declines in the ability to allocate capacity to more than one task • Slower rates of information processing • Age-related declines are not universal • Differences due to: information provided, type and complexity of task, gender, life experience
Long-Term Memory • Involves the ability to remember extensive amounts of information over a few seconds to a few hours to decades • Explicit memory • Deliberate and conscious remembering of information e.g. information from specific event/time, information for facts and concepts • Implicit memory • Change in task performance that is attributable to having been exposed to information at some earlier point in time
Age Differences in Episodic Memory • Older adults perform worse than younger adults on tests of episodic memory recall tests because they • Omit information • Include more intrusions • repeat more previously recalled items • Age differences can be reduced by • Slowing the presentation pace • Providing time to practice • Using familiar stimuli
Age Differences inSemantic Memory • Very small changes in semantic memory with increased age • No differences in language comprehension, and activation of general knowledge • Declines are found in accessibility to semantic memories • Older adults have more trouble finding words and have more tip-of-the-tongue experiences
Memory for Everyday Life • Spatial Memory • Older adults have poorer performance for location than younger adults. However, age differences are typically eliminated when familiar locations/objects are tests or contextual cues are given • Prospective Memory • Remembering to perform a planned act in the future (event vs. time-based) • Age differences are less likely on event-based prospective memory because there are more contextual cues than on time-based tasks
Self-Evaluations of Memory Abilities • Involves making ratings of one’s own memory ability based on • our memory performance, our theories about how memory works, our attributions and judgements of our effectiveness • Older adults view memory as • less stable, expect decline with age, and perceive they have little control over it • Older adults with lower memory self-efficacy translate to poorer memory performance
Memory Strategies • Most memory strategies have several things in common • They require paying attention to the incoming information • Rely on already stored information to facilitate making new connections with the new material • The best strategies are those that, in the process of encoding, provide the basis for future retrieval cues
Defining Intelligence • There are many abilities that underlie intelligence, and are measured using standardized test performance with an emphasis on correct answers • Primary mental abilities • Independent abilities that are measured by intelligence tests and form factors (i.e. verbal meaning, spatial orientation, math reasoning , processing speed etc.) • Age-related changes • There are increases in primary mental abilities until one’s late 30s, scores stabilize until early 60s, and then there are declines until the mid-70s
Secondary Mental Abilities • Broad ranged skills that reflect clusters of several primary mental abilities • Fluid Intelligence: the abilities that make you a flexible and adaptive thinker e.g. solving mazes, puzzles. Shows normative age-related decline • Crystallized intelligence: knowledge you have acquired through life experience and education e.g. definition of words, historical facts and literature. No decline until very late in life
Moderators of Intellectual Change • Cohort differences • Generational differences due to changes in amount of education • Information Processing • Perceptual speed, working memory, and ability to inhibit tend to show decline during later adulthood and account for changes in fluid and crystallized intelligence • Social and Lifestyle Variables • Occupations that require complex thought and independent judgment raise the level of people’s intellectual functioning, as does higher education and SES, exposure to stimulating environments, and strong social connections • Health • Functioning of the brain itself impacts intelligence, such has Alzheimer's disease, depression
Cognitive-Structural Approach • Focuses on the ways in which people think • Piaget’s Theory: intelligence develops through activity which stems from the emergence of increasingly complex cognitive structures • Sensorimotor period: infants gain knowledge via sensory and motor skills • Preoperational: young children’s thinking is often egocentric (all people experience the world just as they do) • Concrete operational: logical reasoning emerges • Formal Operational: thinking in a very systematic, step-by-step way. Approaching problem solving in a logical, methodical way to arrive at one unambiguous solution to the problem
Postformal Thought • Developmental progressions in adult thought • Is characterized by the recognition that truth varies from situation to situation • Ambiguity and contradiction are the rule rather than the exception • Emotion and subjective factors usually play a role in thinking
Reflective Judgment • How people reason through dilemmas involving current affairs, religion, science etc. • Progression from: • Absolutist thinking: believing there is only one correct solution to problems and personal experience provides truth • Relativistic thinking: realizing that there are many sides to any issue and the right answer depends on the circumstance • Dialectical thinkers: see the merit in different viewpoints and are able to synthesize them into a workable solution
