Richard Lazarus
-The appraisal theory of emotion proposes that emotions are extracted from our appraisals of events. These appraisals lead to different specific reactions in different people. -Lazarus also distinguished between primary appraisal, which seeks to establish the significance or meaning of an event, and secondary appraisal, which assesses the ability of the individual to cope with the consequences of the event.
Joseph Le Doux
-To investigate the brain's emotional pathways - 2 pathways- fast route= thalamus to amygdala, less logical thought process, instinctive motor response. Slow route= thalamus to cortex to hippocampus to amygdala, analyzes stimuli to give suitable reaction, logic process took over instinctive emotional responses

Baddeley & Hitch
It is a model of STM and it includes several components: The central executive: a kind of controlling system that monitors and coordinates the operations of the other components, which are called slave systems. Its most important job is attentional control. This happens in two ways: the automatic is based on habit and is controlled automatically (riding bike to school); the supervisory attentional deals with emergencies.The episodic bluffer: Role is to act as a temporary store until the information is needed. The phonological loop: The first component is the articulatory control system, can hold information in a verbal form. The second component is the phonological store, which holds speech-based material. The visuospatial sketchpad: deals with the visual and spatial information from either sensory memory or LTM.
Atkinson & Shiffrin
Multi-score model: model thinks of humans as information processors.The model is based on two assumptions: memory has a number of separate stores; and that memory processes are sequential. Information from the world enters sensory memory--related to different senses. Information stays here for a few seconds, and only a very small part of the information attended to continues into the short-term memory. The capacity of STM is around seven items and duration is normally about 6-12 sec. Material in STM is quickly lost if not given attention. The long-term memory store is conceptualized as a vast storehouse of information.
Albert Ellis
RET
Eric Kandel
Showed that learning means formation of a memory, in other words growing new connections or strengthening existing connections between neurons to form neural networks.
Jean Piaget
T: Schema theory is testable. E: the studies by Anderson & Pitchert and Brewer & Treyens. Applications: Schema theory has been applied to help us understand how memory works. It also is helps us to understand memory distortion. C:Schema cannot be observed. U:Schema theory is applied across cultures. There is no apparent bias in the research P: The theory helps to predict behaviour. We can predict, for example, what types of information will be best recalled when given a list of words.
Walter Cannon
T: Testable → body reaction + adrenaline levels E: Adrenaline increases blood flow, pupils widen, heartbeat becomes faster, loss of hunger, etc A: Applied to living thing/ survival reaction/ survival of the fittest/ evolution C: very valid appears in all animals U: unbiased P: yes, behavior can be predictions
James-Lange Theory of Emotion
T: yes it is E: Yes A: yes, this theory can show us why some feel happier after doing physiological things that activate muscles that you associate with happiness C: Yes U: there is argument that this is biased because you know what is occurring P:yes
Cannon- Bard Theory of Emotion
The Cannon-Bard theory states that the emotional stimulus enters our sensory systems which causes us to feel emotions which causes emotional expression responses (somatic, endocrine, and autonomic). ie. feeling happy makes you smile
Lawrence Kohlberg
Theory of moral development- used Piaget's storytelling technique to tell people stories involving moral dilemmas. In each case he presented a choice to be considered, for example, between the rights of some authority and the needs of some deserving individual who is being unfairly treated.
James McGaugh
stress hormones such as epinephrine and cortisol play a critical part in determining why we remember some things more vividly than others
