Rogues And Spyware: Pegasus Strikes In Spain
Rogues And Spyware: Pegasus Strikes In Spain
Weapons, lacking sentience and moral orientation, are there to be used by all. Once out, these creations can never be rebottled. Effective spyware, that most malicious of surveillance tools, is one such creation, available to entities and governments of all stripes. The targets are standard: dissidents, journalists, legislators, activists, even the odd jurist.
Pegasus spyware, the fiendishly…
What is Intelligence?
- Intelligence: mental quality consisting of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations
- It’s a socially constructed concept that differs from culture to culture.
- Controversies on intelligence: 1. Whether it is one overall ability or many, and 2. Whether neuroscientists can locate and measure intelligence within the brain.
- Toreify intelligence is to treat it as though it were a real object, not an abstract concept.
- Most psychologists now define intelligence as the ability to learn from experience, solve problems, and adapt to new situations.
General Intelligence
- Factor Analysis: a statistical procedure that identifies clusters of related items (called factors) on a test; used to identify different dimensions of performance that underlie one’s total score
- Enables researchers to identify clusters of test items that measure a common ability
- Charles Spearman, who helped develop factor analysis, believed there is also a general intelligence, or, g.
- General intelligence (g): a general intelligence factor that according to Spearman and others underlies specific mental abilities and is therefore measured by every task on an intelligence test
- He proposed that general intelligence is linked to many clusters that can be analyzed by factor analysis
Contemporary Intelligence Theories
- Howard Gardner disputes the idea of one general intelligence
- He proposes 8 independent intelligences: and speculates about a ninth one- existential intelligence which is the ability to think about the question of life, death, and existence.
- Brain damage may diminish one type of ability but not others.
- Savant syndrome: a condition in which a person otherwise limited in mental ability has an exceptional specific skill, such as in computation or drawing.
- Robert Sternberg’s triarchic theory proposes only 3 intelligences: analytical, creative, and practical intelligences.
Emotional Intelligence
- Emotional intelligence: the ability to perceive, understand, manage, and use emotions
- Emotionally intelligent people are self-aware
- Four components:
- Gardner and others criticize the idea of emotional intelligence and question whether we stretch this idea of intelligence too far when we apply it to our emotions.
Intelligence and Creativity
- Creativity: the ability to produce novel and valuable ideas.
- It correlates somewhat with intelligence, but beyond a score of 120, that correlation dwindles.
- Expertise: A well-developed knowledge base.
- Imaginative Thinking: The ability to see things in novel ways.
- Adventuresome Personality: A personality that seeks new experiences rather than following the pack.
- Intrinsic Motivation: A motivation to be creative from within.
- A Creative Environment: A creative and supportive environment allows creativity to bloom.
Is Intelligence Neurologically Measurable?
- Recent Studies indicate some correlation (about +.40) between brain size and intelligence.
- As brain size decreases with age, scores on verbal intelligence tests also decrease.
- Studies of brain functions show that people who score high on intelligence tests perceive stimuli faster, retrieve information from memory quicker, and show faster brain response times.
The Origins of Intelligence Testing
- Intelligence testing: a measure for assessing an individual’s mental aptitudes and comparing them with those of others, using numerical scores
- Alfred Binet and his colleague Théodore Simon practiced a more modern form of intelligence testing by developing questions that would predict children’s future progress in the Paris school system.
- Binet and Simon, set out to recognize a child’s mental age
- Mental age: the chronological age that most typically corresponds to a given level of performance
- Example: a child who does well as the average 8 year old, is said to have a mental age of 8
- In the US, Lewis Terman adapted Binet’s test for American school children and named the test the Stanford-Binet Test.
- Extended the test’s range from teenagers to “superior adults”
- German psychologist William Stern created the “Intelligence quotient” or IQ
Modern Tests of Mental Abilities
- Aptitude tests are intended to predict your ability to learn a new skill
- Achievement tests are intended to reflect what you have already learned.
- Wechsler developed the Wechsler Adult Intelligence Scale (WAIS) and later the Wechsler Intelligence Scale for Children (WISC), an intelligence test for preschoolers.
- WAIS measures overall intelligence and 11 other aspects related to intelligence that are designed to assess clinical and educational problems.
- Separate scored for verbal comprehension, perceptual organization, working memory, and processing speed
- Differences in scores can alert for possible learning problems or brain disorders
Principles of Test Construction
- For a psychological test to be acceptable it must fulfill the following three criteria: Standardization, Reliability, and Validity
Standardization
- Standardizing a test involves administering the test to a representative sample of future test takers in order to establish a basis for meaningful comparison.
- Standardized tests establish a normal distribution of scores on a tested population in a bell-shaped pattern called the normal curve. (bell curve)
- Normal curve: the symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes. Most scores fall near the average, and fewer scores lie near the extremes
- In the past 60 years, intelligence scores have risen steadily by an average of 27 points. This phenomenon is known as the Flynn effect.
Reliability
- A test is reliable when it yields consistent results. To establish reliability researchers establish different procedures:
- To establish reliability researchers establish different procedures:
- Split-half Reliability: Dividing the test into two equal halves and assessing how consistent the scores are.
- Reliability using different tests: Using different forms of the test to measure consistency between them.
- Test-Retest Reliability: Using the same test on two occasions to measure consistency.
Validity
- Reliability of a test does not ensure validity.
- Validity of a test refers to what the test is supposed to measure or predict.
- Content Validity: Refers to the extent a test measures a particular behavior or trait.
- Predictive Validity: Refers to the function of a test in predicting a particular behavior or trait.
The Dynamics of Intelligence
- Intelligence scores become stable after about seven years of age
- A valid intelligence test divides two groups of people into two extremes: the mentally retarded (IQ 70) and individuals with high intelligence (IQ 135).
- Mentally retarded individuals required constant supervision a few decades ago, but with a supportive family environment and special education they can now care for themselves.
- Mental retardation: a condition of limited mental ability, indicated by an intelligence score of 70 or below and difficulty in adapting to the demands of life; varies from mild to profound
- Down syndrome: a condition of retardation and associated physical disorders caused by an extra chromosome in one’s genetic makeup
Genetic Influences
- Studies of twins, family members, and adopted children together support the idea that there is a significant genetic contribution to intelligence.
- Adopted children show a marginal correlation in verbal ability to their adopted parents.
- Fraternal twins raised together tend to show similarity in intelligence scores
- Identical twins raised apart show slightly less similarity in their intelligence scores
- Heritability of intelligence refers to the extent to which variation in intelligence test scores in a group of people being studied is attributable to genetic factors.
- Heritability never applies to an individual’s intelligence, but only to differences among people
Environmental Influences
- Early neglect from caregivers leads children to develop a lack of personal control over the environment, and it impoverishes their intelligence.
- Siblings within impoverished families have more similar intelligence scores which means that among the poor, environmental conditions can override genetic differences.
- Schooling is an experience that pays dividends, which is reflected in intelligence scores.
- High-quality preschool programs can provide at least a small boost to emotional intelligence, which leads to a better attitude towards learning and reduces school dropouts and criminality.
- Increased schooling correlates with higher intelligence scores.
Ethnic Similarities/Differences
- There is a test score gap between races
- However, these group differences are most likely due to environmental differences
- Asian students outperform North American students on math achievement and aptitude tests. But this may reflect conscientiousness more than competence as well as Asian students attending school 30% more days
- Today’s better prepared populations would outperform populations of the 1930s on intelligence tests
- White and black infants tend to score equally well on tests predicting future intelligence
- Different ethnic groups have experienced periods of remarkable achievement in different eras
Gender Similarities/Differences
- Females are better spellers; at the end of high school, only 30% of males spell better than the average female
- Females are verbally fluent and have large vocabularies
- Females are better at locating objects
- Females are more sensitive to touch, taste, and color
- Males outnumber females in counts of underachievement
- Males tend to talk later and stutter more often
- Males outperform females at math problem solving, but underperform at math computation. However, girls are less likely to be encouraged to pursue STEM fields, but as more girls get encouraged this gap is decreasing
- Females detect emotions more easily than men do
The Question of Bias
- Aptitude tests are necessarily biased in the sense that they are sensitive to performance differences caused by cultural differences.
- However, aptitude tests are not biased in the sense that they accurately predict performance of one group over the other.
- A stereotype threat is a self-confirming concern that one will be evaluated based on a negative stereotype.
- Stereotype threat explains why women do better in math tests when men aren’t in the room
Q: Why does my cat understand so many of the words that I say and I understand almost none of his vocalizations? A: There are a lot of factors at play here, so if you want a TLDR answer, you’re out of luck. First, some basics: Some cats are smarter than other cats. And there is a lot we don’t know about animals and cognition. And because cats in particular can’t be bribed reliably with food or a…
Continuing from Part 1, where I explained how we came to keep Stiles, and his relationships with our other cats… Kiki loves elephants and whales, and especially loves watching them if David Attenborough is narrating. She taught Stiles this love of whales, elephants, and David Attenborough from an early age. He’s particularly fond of baby elephants. He hops up on my desk to watch the You Tube…
Today is Stiles’s 2nd birthday. I’ve tried so many different times to figure out how to tell Stiles’s story, and how much he has come to mean to me. I touched on his story a bit when I wrote about his mother, Freya, and also when I wrote about Kagetora. But those mentions barely scratch the surface. I’m going to break this up into several parts since it would make a blog post that is way too…
Q&A How do cats see themselves and us?
Q: Do Cats Think They’re Humans? A: I’m not exactly sure where you got this idea, but it’s a rather simple answer: No. So why bring it up? Because there’s this ridiculous related notion that cats think that we are strange-looking cats. By that logic, they would have to think that their dog friends, bunny friends, and other animal friends are also strange-looking cats, but we know they don’t. Cats…
RCRS: The World’s Only Feline Astronaut
Real Cats, Real Stories is back with a blast from the past. Did you know that a cat went to space? Félicette, a beautiful black and white stray, underwent training along with 13 other cats in France. In the late 50s and early 60s, the space race was starting to heat up. And although we often think of this as a competition between the United States and the Soviet Union, there were other players in…
Wacky Wednesday! If My Cat Were Bigger, Would He Kill Me?
Q: If my cat, who is a gentle house cat, suddenly became as big as a lion, would he kill me? A: That depends on a lot of factors like age, activity level, if he’s neutered, how he plays with you, his personality, and your bond. If he’s young, and very exuberant about play, and is serious about his aggression toward toys, then it’s a possibility. If he was taught (or not corrected—gently and…
Q&A: Are Cats Underrated or Misunderstood?
Q: Are cats the most underrated pet? A: I don’t think they are underrated per se, but they are the most misunderstood pets. When you regularly hear veterinarians and other animal experts repeating myths about cats, it is a sign that those of us who have dedicated our lives studying the little floofy predators have our work cut out for us. I’ve had to correct my cats’ veterinarians on several…
Intelligence is an excellence of mind that is employed within a fairly narrow, immediate, and predictable range; it is a manipulative, adjustive, unfailingly practical quality…Intelligence works within the framework of limited but clearly stated goals, and may be quick to shear away questions of thought that do not seem to help in reaching them. Finally, it is of such universal use that it can daily be seen at work and admired alike by simple or complex minds.
Intellect, on the other hand, is the critical, creative, and contemplative side of mind. Whereas intelligence seeks to grasp, manipulate, re-order, adjust, intellect examines, ponders, wonders, theorizes, criticizes, imagines. Intelligence will seize the immediate meaning in a situation and evaluate it. Intellect evaluates evaluations, and looks for the meanings of situations as a whole…When the difference is so defined, it becomes easier to understand why we sometimes say that a mind of admittedly penetrating intelligence is relatively un-intellectual; and why, by the same token, we see among minds that are unmistakably intellectual a considerable range of intelligence.
—Richard Hofstadter, “Anti-Intellectualism in American Life”
Ne pas céder à la haine, ne rien concéder à la violence, ne pas admettre que nos passions deviennent aveugles, voilà ce que nous pouvons faire encore pour l'amitié et contre l'hitlerisme. Aujourd'hui encore dans quelques journaux, on se laisse aller à la violence et à l'insulte. Mais alors c'est à l'ennemi qu on cède encore. Il s'agit au contraire pour nous de ne jamais laisser la critique rejoindre l'insulte, il s'agit d'admettre que notre contradicteur puisse avoir raison et qu'en tout cas ses raisons même mauvaises, puissent être désintéressés. Il s'agit enfin de refaire notre mentalité politique.
Qu'est ce que cela signifie, si nous y réfléchissons ? Cela signifie que nous devons préserver l'intelligence. Car je suis persuadé que là est le problème. Il y a quelques années, alors que les nazis venaient de prendre le pouvoir, Goering donnait une juste idée de leur philosophie en déclarant: “Quand on me parle d'intelligence je sors mon revolver.”
Albert Camus, in Conférences et discours, texte publié en 1945.
Basing your self worth on your intelligence is a dangerous thing because there will always be someone smarter than you and challenges that seem too great for your intellectual abilities. The stakes become too high and the pressure too great.
