Child: basics Flashcards
What were yerks’ beliefs about intelligence
Intelligence is inherited:
-Concluded that the lighter the skin the higher the IQ
What did Charles spearman (1904) believe about intelligence
- General intelligence can be shown across all IQ tests
- Cognitive skill only
What did Louis Thurston (1938) believe about intelligence
- Cluster of abilities individuals possess in varying degrees (mental capacity)
- verbal comprehension, arithmetic ability etc.
What did Robert Sternberg (1985) believe about intelligence
Triarchic theory of intelligence:
1- Analytical thinking
2- Creative thinking
3- Practical thinking
What did Howard Gardner (1983) believe about intelligence
Multiple intelligences - logical, linguistic, spacial, musical,kinaesthetic, intra/inter personal
What did Daniel Goleman (1996) believe about intelligence
Emotional intelligence - self awareness of our own emotional abilities, motivation and empathy
What were Haier’s (2005) research findings and what this meant in terms of gender differences
Haier found that men have more grey matter in their frontal and parietal lobes, this can create a gender differnce in intelligence as this shows that men are better at: maths, spacial IQ, better drivers, better self-control
Haier also found that women have more grey matter in their frontal lobes and Broca’s area this shows that women are stereotypically proven to talk more and more emotional as well as problem solving, planning and attention
However this also shows that research is not consistent
Define monozygotic twins (MZ)
Identical twins - split to form 2 embryos
Define dizygotic twins (DZ)
Non-identical - Develop from 2 different eggs
Define Genotype
Genetic makeup of an organism with reference to a single trait
Define Phenotype
Physical appearance resulting from inherited information
How do twin studies allow us to investigate the role of nature and nurture in intelligence
-In relation to intelligence, an individual can inherit the genetic potential to be intelligent, but good nurturing (through education/parenting/socialisation) of that potential will effectively switch on the genotype, allowing the potential to be achieved/ expressed
What is the validity for gender differences (neuroanatomy)
Not valid - different types of intelligence, so hard to accurately measure and all studies into the brain have consistent results
- can never have a solid cause and effect conclusion about IQ = not useful
+ Different conclusions = can compare to shoe individuality
What is the freewill/determinism debate on gender differences
Freewill - we choose to learn and react to situations so this could therefore effect our brain plasticity
+can control our actions e.g. Through therapies
Socially sensitive - blaming an individual for their situation e.g. Choosing to be intelligent
What has developed in the brain at conception
- neural tube, brain stem, spinal chord
- brain develops primary functions - reflexes, breathing
- cerebral cortex thickness
What has developed in the brain at one year old
- use their sense of sight to explore an environment and recognise familiar people e.g. Visual cortex
- optimum age to learn symbols, vision, hearing, emotional control e.g. Amygdala
- Motor skills develop - walking, climbing e.g. Pariatal
What has developed in the brain at two years old
-spike in language use (it quadruples) the left hemisphere is dominant
What has developed in the brain at three years old
-recognise basic cognitive functions (thinking, learning, memory problem solving) - limbic system, frontal lobe develops
What examples of risk taking activities might be found more in the adolescent age group
Alcohol, drugs, driving, moving out, meeting new people, travelling,criminal behaviour
What are the functions of the limbic system
Memory, information, emotion, rewards, connecting left and right
What are the functions of the pre-frontal cortex
Morality and values, self-control, inhibition
What are the functions of the ventral striatum
Low delay of gratification, rewards side, activated when sees or receives rewards
Why does this link to risk taking: the limbic system develops earlier than the pre-frontal cortex dominating the controls and decision making of the pre-frontal cortex
-more likely to engage in risk taking behaviour to make you feel good and happy
Why does this link to risk taking behaviour: The ventral striatum matures earlier and is often more dominant than the pre-frontal cortex
-Do anything you can to get a reward regardless of the consequences
E.g. Criminal activity regardless of the long-term consequences
Why does this link to increased risk taking behaviour: The pre-frontal cortex does not mature until the mid-20’s
-Self-control not fully developed, wanting to be impulsive
Why would being present in a group increase the reward sensation activated by the ventral striatum
Stimulation of the rewards centre from getting praise, competition and acceptance from others in a group which stimulates the risk factor
