  3. PSICOMETRIC FOCUS: Methodicalproblems 1. Investigation design: longitudinal or transverse Selection of subjects 2. Familiarity with the work/objectives 3. Influence of speed 4. Tendency to be cautious: Commission errors and omission errors

  4. PSICOMETRIC FOCUS: Methodicalproblems 5. Motivational problems 6. The problem of working with means

  5. PsicometricFocus: InvestigationResults TransverseStudies * Intelligenceclearlydiminisheswithage: itincreasesuntil 20-30 years, staysstable and laterdescends in a slow and steadymanner * There are differencesbetweenabilities: Thepunctuations in themanipulativescaledecrease y in the verbal scalestaythesameordecrease more slowly.

  8. Psicometric Focus: Investigation results Longitudinal Studies * Havenotdetecteddecreasesearlierthan 60 years of age, and somecapacities are preserveduntil 80 years of age. * After 80-85 years, the decline can putdailyfunctioning at risk. * Someabilitiesimprove * Thereispossibly a methodologicalbias

  9. PsicometricFocus: InvestigationResults *Different trajectories for the fluid and crystallized intelligence fluida y para la inteligencia cristalizada FLUID depends more on biological factores CRYSTALLIZED more dependent on cultural factors * Loss or terminal decline

  10. Explanationsforcognitive decline Hypotheses centered on the Hardware or Structure * Sickness (especially cardiovascular and arthritis) *Hypothesis of speed or peripheral slowing down *Hypothesis of general slowing down * Hypothesis of the reduction of resources: attention, working memory, mental energy…

  11. ExplanationsforCognitive Decline Hypothesiscenteredon Software orSystemfunctioning *Hypothesis of thelack of use (current and pastintellectualstimulation) *Hypothesis of insufficientstrategies * Hypothesis of contextual and generationalchanges

  12. SuccessfulCognitiveAging According to Salthouse Accomodation: Tendency to disconnect yourself gradually from activities that supercede your cognitive limitations and to focus on other activities Compensation: The same efficiency is maintained by changing the manner of completing work Reparation: Intervention or training to restore cognitive abilities to a previous level

  13. Successfulcognitiveaging AccordingtoSalthouse Cognitiveefficiency can be maintainedwithstrategiesthatmaximizeonstrongpoints and minimizeonweakpoints.

  14. SuccessfulCognitiveAging According to Baltes CognitivePragmatics Contextualizedcapacities Formal and Informal learning CognitiveMechanics Basic cognitiveprocesses Biological and cerebral Results of informationprocessing

  15. SuccessfulCognitiveAging According to Baltes Functional base: habitual functioning The reserve capacity decreases with age, although it only disappears completely with dementia.  learning potential Processing information evaluates the Base Reserve and cognitive mechanics maximize the differences not so called upon in daily life Base Reserve: maximumefficiencypotential PLASTICITY Development reserve: Maximumefficiencypotentialwithhelp: instrumental or personal

  16. SuccessfulCognitiveAging Mastery or Being an Expert *Development of abilities and advanced knowledge in a professional activity or field * Better sensibility to aspects relevant to a problem * Better maintenance of information in the MLP * Result of learning and practice * Effectively getting close to problems and absence of transfer * Cognitive functioning is stable in these areas, even though there are other intellectual losses  cognitive pragmatics

  17. SuccessfulCognitiveAging According to Baltes Anteceding conditions: Development is essentially a process of selective adaptation The limit of resources adds an additional adaptive pressure. More pressure comes from the changes associated with the age in plasticity and availability of external and internal resources. Results: Maximization of wins and minimization of losses Successful development or consecution of priority goals Maintaining function Recuperation of the los of select fields Regulation of loss (reorganization of function in inferior levels) Processes: Selection – Identification of fields and direction of the process of change. Restriction of many behaviors and potential goals. Optimization – Better the means directed to the goals that are available. Search of favorable environments. Compensation – Adquire new external and internal means to achieve goals, due to: • Lost means that were available earlier • Contexts and adaptive fields have changed Tomado de Villar, F Titularidad.

  18. InformationProcessing DeclarativeMemory Attentionalprocesses Information Output

  19. InformationProcessing: Attention Thereductionwithage in thelimitedresource, necessarytoprocessinformation, would reduce efficiency en cognitiveprocesses. SustainedAttention Notveryaffectedwithage. Seniors are less precise en vigilancetestssincethebeginning. This can diminishduetofactorslikethediscriminabilityortheduration of stimuli.

  20. InformationProcessing: Attention Selective Attention The ability to focus on important information without valuing the irrelevant aspects decreases with complex tests. Divided Attention – Change of Attention Deterioration with complex works in divided attention. Equal efficiency as young people, although they are slower, in changing attention. Practice can prevent this. Worse efficiency with inhibitory mechanisms

  21. InformationProcessing: Memory Some types of memory are affected by old age while others stay intact. Sensorial Memory The majority of studies are about visual iconic memory and indicate that despite changes in vision, the effects of aging are unimportant. It is difficult to evaluate due to the complicated distinction between the role of the senses and that of the sensorial memory.

  22. InformationProcessing: Memory Short-TermMemory and OperativeMemory Short-Term differences exist en experimental situations with tests that accentuate daily situations and in linguistic or visual experiments. Bigger problems when the work is complicated (Operative Memory)  enters the game of the executive center (attentional processes) - Diminishment of the Operative memory capacity?

  23. InformationProcessing: Memory Secondaryor Long-TermMemory Explicaciones de las pérdidas (Light, 1991 en Pousada y de la Fuente, 2006) * Codification: Have not found empirical evidence of the idea that seniors use a more superficial process than younger people. * Recuperation: Seniors show more difficulties en some works (word recall) and are similar in others (implicit memory, recognition, recall with clues)  the information is available (equal capacity of *storage) but not accessible.

  24. InformationProcessing: Memory EpisodicMemory * Empiricalevidence of animportantdeteriorationafter 30-40 years > Short-TermMemory, procedural orsemantic * Fewdifferences in the control of reality * Thesame in thewaythe fluid intelligencemanages new information: theevents are unpredictable. Impossibleto use routinesorlearnedschemestocodethem. * Thedeficits are reducedwith contextual helpinginformation in thecodification and recuperation.

  25. InformationProcessing: Memory SemanticMemory • * Memory of dissociatedfacts of when and where. • * Scarcedeterioriationwithage, althoughthere are somedeficits: faults in findingwords and forgettingnames. • * Compensatethesedeficitswith a betteraccumulatedknowledge. • Importance of thespecificity of the material toremember: episodic= specificitysemantic= no specificity • * Forgettingthesource

  28. InformationProcessing: Memory Longitudinal Studies (Victoria y Betula) SemanticMemory Worsenswithage. Young generationshaveworseefficiency, which can hidethe decline withage.

  29. InformationProcessing: Memory Longitudinal Studies Decrease in EpisodicMemory ProspectiveMemory Preserve thecapacities of DividedAttention

  30. InformationProcessing: Memory CONCLUSIONS • Changes related to age exist in memory and attention • MULTIDIRECCIONALITY: stability and decline that increase after 75 years • Important INDIVIDUAL DIFFERENCES

  31. InformationProcessing: Role of education Lower education level Faster memory deterioration and lower verbal abilities EDUCATION MEMORY SOCIO-EMOTIONAL EXPERIENCE HEALTHY HABITS

  32. InformationProcessing: Role of education • Cognitive Reserve • Different neuronal circuitsparticipate en theexecution of thesameworkwithorwithouteducation. • Thisiswhydementiaisdetectedlater. • Formal educationislessimportantthanrichcognitiveexperience.

  33. Models of stages: PostformalThought * Criticisms of postformal thought as a goal of development Decrements with age in the capacity to resolve formal work. Formal works do not relate to daily problems. Ignorance of contextual and emotional aspects.

  34. Models of Stages: PostformalThought Caracteristics of postformal thought Surges in the middle age with experience Qualitatively different from formal: integrates logical and analitical reasoning with intuition There is no uniform conception of postformal though More interpretive and relativistic Multicausality and multiple solutions

  35. Models of Stages: PostformalThought Caracteristics of postformal thought Admits contradiction as a basic aspect of reality Dialectic reasoning: capacity to integrate contradictory information Finds new problems Is pragmatic and permits better resolving social dilemmas Find the key elements of an ambiguous and poorly-defined problem

  36. Wisdom • Forgotten and barely studied aspect of development • Exceptional comprehension based in experience (cognitive pragmatics) • Mastery en pragmatic themes of life (planning, control, vital or sensorial revision) • Related to age • Erikson (cognitive development – socio-emotional development)

  37. Wisdom Criteria (Baltes) Extensivedeclarativeknowledgeaboutlife (knowwhat) Extensivepracticalknowledgeaboutlife (knowhow) Understandingthelife as a collection of interrelatedcontexts and changesthroughoutlife Cultural relativismalthoughthere are universal values Metaknowledge(fallibility, relativism, uncertainty)

  38. Wisdom Responsible Factors Context and favorable environments/experiences (cultural level, profession as an educator or directing others, …) Experience in planning, management and vital revision as a resolution of problems, to be a mentor or advisor, motivation for human themes or an impulse to better and personal excellence Personal disposition like creativity, intelligence, flexibility, open to new experiences

  39. Wisdom Evaluated with moral dilemmas like the following: “A good friend calls and says they are going to commit suicide: What should you do and take into account?” Only 5% of people appear wise. This percentage is maintained through generations (perhaps you are wise en aspects relative to your generation and moment in life) The number of wise answers increases with clinical psychologists or when they are resolved en groups.

  40. Wisdom • Criticism of the Baltes Model and the Vision of Ardelt Baltes is too cognitive, 3 components are necessary • Cognitive component similar to that of Baltes • Reflexive component – to transcend your own point of view y take others into account, this requires self-consciousness • Affective component or to sympathize and love others, and to want common wellbeing • - Similar to Erikson’s idea of wisdom of integriy – related with self-esteem and wellbeing

  41. Creativity • Divergent thought – alternate solutions • Reaches the best level between 35-45 years • Different curves in distinct areas: • Math, physics, poetry at 20 years • Philosophy , history, literature at 50 years • * The song of the poet (El canto de cisne)
