have to rehearse to go in to long term memory

retrieving the trace
is like completing the fragment eg Pe** retrieval is recall
Damage to the Medial Temporal Lobes disrupts what
ability to consciously remember anything that happens after injury.
Left PFC stimulation at ~500ms after seeing a picture disrupted further recognition

Stress reduces attention to irrelevant information
Booth and Sharma (2009)
➢ that amygdala damage can have distant consequences on what
on visual cortex function, selectively affecting emotional modulation.
Dot probe task:
The emotional pictures dot-probe task is a spatially oriented motivated attention task that is administered via computer to capture attentional bias toward emotional cues.
LeDoux (e.g. 1995
has proposed a dual-route for processing of threatening stimuli. slow, conscious, cortical versus fast, unconscious, subcortical.
. Loftus, et al., 1987
Eyewitnesses often fail to recognise crime perpetrator while still remembering lots of details of the weapon. Eye witness testimony is affected by stress, reconstruvctive memory, weapon focus and leading questions. In restaurant customer held gun or checkbook, less likely to identify person holding a gun
Yuille and Cutshall (1986)
contradicts the importance of weapon focus in influencing eyewitness memory. Used real life robbery case. The misleading information had little effect on the witnesses. 10 out of 13 of them said there was no broken headlight or yellow quarter panel, or that they hadn’t noticed those particular details. Errors were still relatively rare and the accuracy remained high 5 or 5 months later-flashbulb memory? Only 13 participants
➢ Bower’s (1981)
network theory of emotion.
Emotion is a “node” in a network of associated semantic concepts.
Activation spreads throughout the network between related concepts.
Emotion nodes in network are activated by an internal or external cue, and when activity reaches above a threshold, the emotion is experienced.
Through links, other associated concepts and memories are also activated and consciously retrieved.
Eg loss, despair, unworthiness
Information is more easily encoded when congruent with current mood, because it can be linked with other, related information in active network (causing elaborative encoding).
Likewise, information is more easily retrieved when congruent with current mood, because activation of the emotion node spreads to related information such as memories.
Mood-state-dependent memory: memory should be best when the mood at retrieval matches mood at the time of encoding (without considering type of information).
The same schema that was active at the time of encoding needs to be activated at retrieval for successful remembering. Thus, reinstating a similar mood makes it more likely that encoded information will be retrieved.
Lazarus (e.g. 1982) appraisal theory
Emotional experience depends on our conscious or unconscious cognitive evaluation (appraisal) of a situation.
Situations are judged negative, positive or neutral based on their personal significance.
Appraisals also takes into account how to cope with situation.
Speisman et al., 1964).
➢ Participants saw anxiety-evoking film on an aboriginal initiation ceremony with mutilations
➢ The film was shown with three different audio tracks intended to manipulate emotional reactions:
➢ Trauma condition – emphasis on the mutilation and pain
➢ Intellectualisation condition – the track gave an objective anthropological viewpoint on the surgery
➢ Denial condition – boys were shown as happy and willing to participate at the ceremony
➢ Control – no audio
➢ Heart rate, galvanic skin response, blood pressure
➢ Subjective reports
➢ Participants in the Trauma condition showed higher physiological measures of stress than participants in the other conditions
➢ Suggests that it’s the individual interpretation of the event that affects emotional reaction rather than the event itself-supports appraisal thwory
➢ Meta-analysis of 43 emotion regulation studies (Ochsner, Silver & Buhle, 2012)
Blue boxes – areas involved in “top-down” control over emotional areas.
Pink box – emotion regions modulated by “top-down control.
Consistent with general role of PFC in control over other brain areas (cf. cognitive control lecture).
During re-appraisal, as PFC activation increases, amygdala activity decreases
Have cognitive biases with depression/anxiety
Attentional bias:
selective attention to threat-related stimuli presented at the same time as neutral stimuli.
