Sports Performance Flashcards
Hopkins and Westra 1989
Adolph 1998
Opposing Gesel 1954 idea that stages are fixed
28% of Jamaicans missed out crawling
Similar finding in the USA
Dennis 1960
ENVIRONMENTAL INFLUENCE
Iranian orphanage infants lay on their backs
Didn’t move until 2yrs old
Only 15% could walk aged 3-4
Delayed development
Back to sleep campaign
Kids placed on backs to sleep
Delayed motor development
This is reduced by tummy time during the day
White and held 1966
ENVIRONMENTAL INFLUENCE
Institutionalised babies, stimulation and reaching reflex
Low, moderate and lots of stimulation
The moderate group developed best
The high group were overwhelmed and looked away from their stimuli a lot
Venetsanou and kambas 2010
ENVIRONMENTAL INFLUENCE
Reviewed environmental factors affecting pre school performance
Mothers education
Socioeconomic class
Number of siblings (younger walk sooner)
Weird norms
Western Education Industrialised Rich Democratic society
Represent less than 5% of world population
Karasik et al 2015
CULTURAL INFLUENCES
babies sitting
Italian babies spent most time in mothers arms
Kenyan and Cameroonian babies spent most time on the floor sitting independently
Kenyan babies could sit for longest
Sitting location is relevant for developing posture and balance.
Lots of variation within and between groups
Adolph et al 2010
Reviewed lots of work on cultural influences
Concluded that cultural differences are present.
Studies showed Uganda babies develop faster than USA
Massaging and informal handling improves development- techniques vary a lot in cultures
Drowatsky et al 1967
.? General motor ability
There should be a correlation between 2 skills if this is the case…
They found no correlation so it’s unlikely that a general motor ability exists
Henry 1950s
Specific motor ability theory
Theorised that abilities were so specific that they would not overlap between tasks and therefore there should be no correlation at al between tasks.
Fleishman 1964
Disagreed with Henry- proposed a more general theory
Factor analysis to group abilities
- perceptual motor abilities
- physical proficiency
Ability may overlap for similar tasks
Abilities required may change with age and experience
Murray et al 2007
Motor milestones in later life…
Asked mothers to say when their children developed various milestones
IQ tests ages 8, 23, 56
increase in IQ at age 8 when early development
Reduces with age
Not likely to affect you later in life unless severely delayed
Diversity
Range of scores in a group
Dispersion
Range of scores of an individual against their mean
Consistency
Variability over time
