SEMESTER 2 EXAM FLASH CARDS
(197 cards)
Dunphy
Stage 1: early adolescent -cliques
4-8 members of same sex , isolated groups
Dunphy
Stage 2: Development of the crowd
Unisex groups start to interact with other groups
Dunphy
Stage 3: Unisex groups form heterosexual cliques
Forming heterosexual groups, dating occurs in upper-status members
Dunphy
Stage 4: Fully developed crowd; heterosexual cliques in close association
Heterosexual groups in close association
Dunphy
Stage 5: Crowd disintegration
Couples break away from the group
PET scan
Position emission tomography
•PET scans are based on the glucose (sugar) consumption of the brain.
A radioactive tracer that decays by emitting a position is injected in to the body, usually the blood stream.
•Sugar is weakly radioactive and a PET scan can show which areas of the brain are using more energy or consuming more glucose.
•Higher glucose levels reflect higher brain activity
•By placing positron detectors around the brain and picking up the activity, the computer generates pictures based on the metabolic information
•Used alongside MRI as they provide specific information about areas of the brain that can be linked to particular activities such as reading, where there are tumours or damage.
FMRI scan
Functional magnetic resonance imaging
FMRI is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled.
CAT scan
Computerised axial tomography
A type of x-ray that translates the scanned picture into a clear two dimensional image of the brain via the computer.
Scans through 180 degrees and takes a measurement every 1 degree, giving rise to the pictures.
CAT scans aid in the detection of tumours, strokes and other injuries, which can aid in finding out the reasons for changed behaviour and personality
MRI scan
Magnetic resonance imaging
Uses a strong magnetic field rather than an x-ray to produce an image of the brain. The patient is placed in a magnetic field and is then scanned.
The resulting image is a computer-enhanced three-dimensional picture of the brain (or the body) from which a two dimensional ‘slice’ can be selected and displayed, rotated or enlarged
This enables detection of tumours and other abnormalities, which again can be linked to altered behaviours or personality characteristics.
EEG scan
electroencephalography
Used when we want to investigate the whole brain rather than parts.
An EEG measures brain waves or electrical activity in the brain
Different patterns or brain waves can indicate problems with the brain such as epilepsy or tumours, as well as being used to describe various types of behaviour such as sleeping and the effects of hypnosis which alter these patterns
What are some (3) cultural differences in non-verbal communication:
- Facial expressions: Western cultures facial expressions are more severe/ exaggerated than Eastern cultures
- Gestures: In Thailand beckening someone with your palm up is rude, so they do it with their palm down
- Body language: In Middle Eastern countries it is insulting to cross an ankle over a knee and display the sole of the shoe while talking to another person
Type of non-verbal communication:
•Touch and smell
Smells have the power to conjure up memories and emotions
Eg. Breastfeeding
Cultural variables: in some Asian countries it is not acceptable to breastfeed babies
Common obstacles of effective communication:
- Being distracted and only listening with ‘half an ear’: The listener may pretend to be listening, giving eye contact and saying ‘uh huh’, ‘really’, etc. at appropriate times but they are really thinking about other things.
- ‘topping’ the speaker: the listener follows the conversation until they have heard something they can top with a better story.
- Being judgemental: saying or implying, ‘you should have known better’ or ‘I told you so’
Crowd
Larger groups of adolescence (or others) with similar identities or affiliations
Such as Eagles or Dockers supporters at a home game
Clique:
Small groups who interact frequently
Dyad:
Pairs of close friends or lovers.
Peers
People who interact on fairly equal terms, i.e. They have similar status and are usually of similar age and have similar interests
Liking definition
A feeling of regard or fondness
Difference between pro-social and anti-social behaviour
Prosocial behaviour is any behaviour intended to help or benefit another person, group or society, whereas Anti-social behaviour is any behaviour that is disruptive or harmful to the wellbeing or property of another person or to the functioning of a group or a society.
What are 3 determinants of liking:
- similarity
- proximity
- reciprocity
Reciprocity
•knowing or thinking someone likes us is enough to make us attracted to them
Eg. Inviting us to their party, being paid a compliment, etc.
Relational influence:
•proximity/ propinquity:
In order to develop friendships, you have to meet these friends, so physical proximity is essential.
Living close by is a major factor in the development of friendships and longer term relationships.
This is due to 3 factors believed to be linked to physical closeness.
These include:
•familiarity
•availability
•expectation of continued social interaction
Relational influences:
Similarity
For many friends and couples, there are similarities in their attitudes and values, their dress, their level of education and their views about politics and religion.
Communication between potential friends must take place and this often occurs when mutual attraction has been signalled.
Curiously, mutual attraction is sometimes based on the degree of similarities between people.
Group testing
Refers to any procedure which breaks up the task of locating elements of a set which have certain properties into tests on subsets(‘groups’) rather than on individual elements.
