A. Introduction

Personality theories

Type

People are qualitativly differnt

the four humours

MBTI

Trait

people vary on certain dimesions

Eysencks EPI

Costa McCrae

Big 5

Temperament

Def.

(TempoSition) Disposition to act in particular ways accross time and situation not regarding the influence of cognition. Tought to be inherited.

B. What and when ?

Agreement on 3 broad categories

emotional

attentional

Motor activity

Important temperamental differences
and time of emergence (contrad. to def)

very early

Inhibition (s. Kagan)

very late

effortful Control (i.e. Rothbart)

inhibition to persue a goal

But: Other genetic factors like intelligence also only experess themselves later

variation accross time

stabilty

same behaviour over days or weeks

continuity

similar characteristics accross time

C. What'sthe cause?

Genetic origin

Buss& Plomins: Minnesota Twins correlation

sociability

activity

But: MZ often similar environm.

7r Dopamine Receptors

Auerbach: General:

Dopamine receptor assotiated
with temperamental differnces

Schmidt's: Older Kids

Problem with attention, risk taking and aggressive behaviour

MAOA(m) re-uptake

Caspi et al

Seronotine transporter: aggressive only with kids who been in abusive environment.

D. How stable is it

Short Term: high stability

Plomin: Colorado Adoption Project

high stability from 1-4

emotionality

sociability

less stability

activity

But: based on parental ratings (sim to previous)

Hinde & Tobin

4 y

assessment at home and in play group

"coherence of termperament" across contexts

Gender: behvioural differneces

Shy

G: better rel. w. mother

G. Less hostile w. peers

Long Term: clear relationship

Caspi et al: 1000 3y

cat in 5 Types

26

MPQ

self

Big 5

close friend

E. Methods

parental observations

good acces but biased

But: Hagekull: Good corrlation between partents reporst and direct observation

face to face Interviews

potentially more accurate

social desirealbilty or problems with understanding

F. 4 Termp Theories

Thomas&Chess'9

9 Dimesions

i.e distractibilty and attention span

But: Some factors possibly overlapping

Also 3 Types

difficult child(increased risk of later behvour problems)

mood

adaptabilty

rhythmicality

approach

slow to warm up

easy child

Bates& Bales: Mother problems

link of problem behav reported by mom at 2y with later 3-6y

But

Pauli&Potts: emotionality at 4 p

erceptios of emotionality at 4m predict measurement at 8

Vaughan's Uterus

Mothers formed a view before child was born: Ratings of temperament related to mothers personality and attitudes on child rearing

Kagen's inhibited child

Kagen found a type that shows strong behavioral inhibition i.e. to new things

75% stabilty

Linked with later problem behaviour

links this to arrousal level in the limbic system

change possible with concious effort

Bus and Plomin's EAS

EAS framwork

factor analysis

Emotinality/ Activiy / Sociability

Links well with Eysencks: EPI

Neuroticism

Extroversion

Dunn&Kendrick: jealousy

Importance of environment

siblings reaction to newborn not only related to temperament but quality and stability of interaction.

G. Temp and Development
(how genes and environment interact)

Scarr's PA 3 interations

passive: sharing char.

active: self selection

evocative: child evokes response

Direct effects

Keogh: in School

Factors like attention or impulisivity

Dunn & Kendrick

More stressed on arrival of sibling

self-selection of environments

Transactions

Goodness of fit

Isabella: caregiver personality not corr with child attachment but interaction is.

Sameroff: Transactions

influnencing behaviour of caregivers
