Q

what rogers developed

A

In order to reduce the gap between the perceived self and the ideal self, Rogers developed client centered therapy to help those cope with the problems of everyday living. ​
Rogers claimed that many of the issues we experience as adults such as worthlessness and low self-esteem is due to childhood and a lack of unconditional positive regard. ​
A parent who sets boundaries or limits on their love for their child – conditions of worth builds of psychological problems for that child in the future. ​
Rogers says to be an effective therapist – you should provide clients with unconditional positive regard they failed to receive as children

Gannon L

A

It is not possible to falsify the assumption that human thoughts and behavior are driven by evolved predispositions, which make the approach unscientific.

Q

Banduras method

A

2 groups. One group of children were in a room with an adult that shouted abuse at a doll and hit it with a hammer.​
The other group, the ‘control group’ saw non-aggressive behaviour from adults towards the dolls.​
Results​
The children were put in a room alone. ​
High levels of aggressive behaviour was apparent from children who had observed aggression.​
Conclusions​
Boys were also more aggressive than girls.​
Exposure led to aggressive behaviour.​

Q

bandura 77

A

Three main characteristics that make you likely to influence the observer and thus increase the likelihood of imitation:​

The more similar the model is seen to be by the observer. (Age/sex)​

Behaviour that is simple and easy is more likely to be imitated.​

Aggressive and antisocial behaviour is also more likely to be imitated (eg Bandura’s original study emphasises this.)

Q

what darken said about bandora

A

Where else in life does a 5 year old find a powerful adult actually showing you how to knock hell out of a dummy and then giving you the opportunity to try it out yourself’‘(Durkin, 1995)​

Q

what bandora thought

A

The Social Learning Theory is a Social Psychological theory which psychologists use to explain aggression.​

Bandura combines the logic of social and cognitive psychology to create another social psychological theory to explain aggression which he termed the social cognitive perspective.​

Bandura thought that behaviour may be motivated not only by inherent psychological factors, but also by socio-environmental factors.​

He argued that the individual and the social environment were linked. He called this reciprocal determinism

Q

weaknesses of Wundt

A

Scientific psychologists create contrived situations that create artificial behaviours​
Much of the subject matter of psychology is unobservable, therefore cannot be measured with any degree of accuracy​
Not all psychologists share the view that that human behaviour can be explored through scientific methods

Q

outline wundes method of introspection

A

*   introspection is a systematic analysis of one’s own conscious experience​
*   experiences are analysed in terms of their component parts/reference to ‘structuralism’​
*   these parts are elements like sensation, emotional reactions etc​
*   people were trained to do this analysis to make the data objective rather than subjective​
*   people were presented with standardised sensory events like a ticking metronome and asked to report their reactions.​
Credit other relevant description of the method of introspection.​

Q

little hans

A

ported his theory of the Oedipus Complex with the case of Little Hans. Hans was a five-year old boy who developed a phobia of horses after seeing one collapse. Freud suggested his phobia was a form of displacement in which his repressed fear of his father was displaced onto the horse. Horses were symbolic of Hans’ real unconscious fear – Castration

27
Q

siffre

A

He went into the cave on 16 July 1962 and came out of the cave on 14 September 1962. However, Siffre thought the day he came out – two months after he had entered the cave was the 20th of August, showing how his time in the cave had warped his sense of time.​

Siffre’s ‘free-running’ biological rhythm had settled into a sleep-wake cycle of around 24 hours and 30 minutes. Although he did continue to fall asleep and wake up on a regular schedule

28
Q

findings of siffre

A

After a 2-month cave stay, in 1972, he then lived in a cave for 6 months! His findings were: ​


He settled into a sleep/wake cycle usually just beyond the usual 24-hour cycle – 24.5hours​

“My sleep was perfect! My body chose by itself when ​
to sleep and when to eat.” ​

Supports the assumption that endogenous pacemakers exert an influence​

However, by the end of it he was very lonely and slightly depressed

Q

Aschoff and weaver

A

. A group of participants spent four weeks in a bunker deprived of natural light during WWII​
All participants except one (who displayed an extended sleep/wake cycle of 29 hours) displayed a circadian rhythm of between 24 and 25 hours. ​

Both Siffre and Wever’s studies suggest that the ‘natural’ sleep/wake cycle may be slightly longer than 24 hours but that it is entrained by exogenous zeitgebers associated with our 24-hour day ​

30
Q

folkard

A

studied a group of 12 people who agreed to live in a dark cave for 3 weeks – going to bed when the clock said 11:45pm and waking up when it said 7:45am. Over the course of the study, the researchers gradually speeded up the clock (the participants were not aware of this). So, an apparent 24-hour day was instead only 22 hours

31
Q

folkards findingds

A

t was revealed that only one of the 12 participants were able to comfortable adjust to this new 22-hour day suggesting the existence of a strong free-running circadian rhythm that cannot be overridden by changes in the external environment​

32
Q

tucker et al

A

found significant differences between participants in terms of the duration of each stage, particularly stages 3 and 4 (just before REM sleep). ​
E: In addition, this study was carried out in a controlled lab setting, which meant that the differences in the sleep patterns could not be attributed to situational factors​
L: This demonstrates that there may be innate individual differences in ultradian rhythms, which means that it is worth focusing on these differences during investigations into sleep cycle

33
Q

kleitman and dement

A

monitored the sleep activity of 9 adults in a sleep lab ​
E: Brain-wave activity was recorded on an EEG and the researchers controlled for the effects of alcohol and caffeine. ​
L: REM activity during sleep was highly correlated with the experience of dreaming, brain activity varied with how vivid the dreams were and participants that were woken during their sleep recorded very accurate, detailed reports of their dreams ​
Additionally, replications of this study have noted similar findings although he sample size of the initial study has been criticised by some. Nevertheless, this study shows that REM sleep is an important stage in the stages of sleep.​

34
Q

mclinctock and stern

A

demonstrated how women’s menstrual cycles can synchronise as a result of female pheromones. ​
They gathered 29 women with irregular periods. Samples of pheromones were gathered from 9 of the women at different stages of their menstrual cycles, via a cotton pad placed in their armpit. ​
The pads were worn for at least 8 hours to ensure that the pheromones were actually picked up on the cotton pads. The pads were treated with alcohol and frozen, so that they could later be rubbed onto the upper lip of the other 20 female participants. ​
On day one, pads from the start of the menstrual cycle were applied to all 20 women, on day two they were all given a pad from the second day of the women’s cycle and so on. ​
They found that 68% of women experienced changes to their cycle which brought them closer to the cycle of their ‘odour donor.’​

35
Q

russel et al

A

ound that female menstrual cycles became synchronised with other females through odour exposure. ​
E: In one study, sweat samples from one group of women were rubbed onto the upper lip of another group. Despite the fact that the two groups were separate, their menstrual cycles synchronised. This suggests that the synchronisation of menstrual cycles can be affected by pheromones, which have an effect on people nearby rather than on the person producing them. ​
L: These findings indicate that external factors must be taken into consideration when investigating infradian rhythms and that perhaps a more holistic approach should be taken, as opposed to a reductionist approach that considers only endogenous influences. ​

36
Q

reinberg

A

There is research support. Research suggests that the menstrual cycle is, to some extent, governed by exogenous zeitgebers (external factors). Reinberg (1967) examined a woman who spent three months in a cave with only a small lamp to provide light. Reinberg noted that her menstrual cycle shortened from the usual 28 days to 25.7 days. This result suggests that the lack of light (an exogenous zeitgeber) in the cave affected her menstrual cycle, and therefore this demonstrates the effect of external factors on infradian rhythms. ​

37
Q

terman

A

Finally, evidence supports the role of melatonin in SAD. Terman (1988) found that the rate of SAD is more common in Northern countries where the winter nights are longer. For example, Terman found that SAD affects roughly 10% of people living in New Hampshire (a northern part of the US) and only 2% of residents in southern Florida. These results suggest that SAD is in part affected by light (exogenous zeitgeber) that results in increased levels of melatonin. ​

38
Q

decoursey et al

A

destroyed the SCN connections in the brains of 30 chipmunks who were then returned to their natural habitat and observed for 80 days.​

Their sleep/wake cycle of the chipmunks who had their SCNs destroyed disappeared, and by the end of the study a significant number of chipmunks were killed by predators.​

39
Q

Martin Ralph

A

Bred ‘mutant’ hamsters with a 20-hour sleep/wake cycle. ​
When the SCN cells from the foetal tissue of mutant hamsters were transplanted to the brains of normal hamsters, the cycles of sleep/wake defaulted to 20 hours. ​

40
Q

campbell murphey

A

), they demonstrated that light may be detected by skin receptor sites on the body even when the same information is not received by the eyes. They had 15 participants who they woke up at various times and a light pad was shone at the back of their knees. The researchers managed to produce a deviation in the participants usual sleep/wake cycle by up to three hours. ​

This suggests that light is a powerful exogenous zeitgeber that does not necessarily need to rely on the eyes to exert its influence on the brain. ​

41
Q

klein and Wegmann

A

Klein and Wegmann (1974) found the circadian rhythms of air travellers adjusted more quickly if they went outside more and right after landing at their destination, possibly because they were exposed to social cues that acted as zeitgebers.​

42
Q

Morgan

A

red hamsters so that they had circadian rhythms of 20 hours rather than 24. ​
E: SCN neurons from these abnormal hamsters were transplanted into the brains of normal hamsters, which subsequently displayed the same abnormal circadian rhythm of 20 hours, showing that the transplanted SCN had imposed its pattern onto the hamsters. ​
L: This research demonstrates the significance of the SCN and how endogenous pacemakers are important for biological circadian rhythms. ​
However, this research is flawed because of its use of hamsters. Humans would respond very differently to manipulations of their biological rhythms, not only because we are different biologically, but also because of the vast differences between environmental contexts. This makes research carried out on other animals unable to explain the role of endogenous pacemakers in the biological processes of humans

43
Q

miles

A

Miles et al (1977) noted the story of a blind young man from birth with a circadian rhythm of 24.9 hours. Despite constant exposure to social cues his sleep/work cycle could not be adjusted and he had to take sedatives at night and stimulants in the morning to keep up with the pace of a 24-hour work world​
E: similarly, studies of individuals who live in arctic regions (where the sun doesn’t set during the summer months) show normal sleep patterns despite the prolonged exposure to the light. ​
L: Both of these examples suggest that there are occasions when exogenous zeitgebers may have little bearing on our internal rhythm​

43
Q

Phineas gage

A

1848 while working on a rail line, experienced a drastic accident in which a piece of iron went through his skull. After the accident he experienced a change in personality, such as loss of inhibition and anger. ​
This change provided evidence to support the theory of localisation of brain function, as it was believed that the area the iron stake damaged was responsible for personality.​

44
Q

patient tan

A

Broca’s area is named after Paul Broca, who discovered this region while treating a patient named Leborgne, who was more commonly referred to as ‘Tan’. ​
After Tan’s death, Broca conducted a post-mortem examination on Tan’s brain and discovered that he had a lesion in the left frontal lobe​

45
Q

Doidge

A

Doidge (2007) conducted research on brain plasticity and showed that the brain can rewire and reorganise itself after brain injury by forming new synaptic connections close to the area of damage. He also found that secondary neural pathways that would not typically be used to carry out certain functions are activated to enable functioning to continue. The brain can rewire itself via axonal sprouting (growth of new nerve endings) or via recruitment of homologous (an area of the opposite side of the brain takes over to perform that function).

46
Q

dronkers

A

conducted an MRI scan on Tan’s brain, to try to confirm Broca’s findings. Although there was a lesion found in Broca’s area, they also found evidence to suggest other areas may have contributed to the failure in speech production.​
E: These results suggest that the Broca’s area may not be the only region responsible for speech production and the deficits found in patients with Broca’s aphasia could be the result of damage to other neighboring regions.​
L: Therefore, there is inconclusive research to claim whether the brain’s functions are localised in specific regions. ​

47
Q

lashley

A

claimed that the basic motor and sensory functions are localised, but that higher mental functions such as memory or language are not. He claimed that intact areas of the cortex could take over responsibility for specific cognitive functions following brain injury. ​
E: This therefore casts doubt on theories about the localisation of functions, suggesting that functions are not localised to just one region, as other regions can take over specific functions following brain injury. ​
L: This decreases the credibility of the claim that each function is located in one specific part of the brain and if this area is damaged, that function will never be recovered. ​

48
Q

Maguire aim

A

To examine whether structural changes could be detected in the brain of people with extensive experience of spatial navigation

49
Q

maguire method

A

structural MRI scans were obtained. ​
Experimental group: 16 right-handed male London taxi drivers participated. All had been driving for more than 1.5 years. (from 1.5 to 42 years) ​
Control group: 50 healthy right-handed males who did not drive taxis were included for comparison. The mean age did not differ between the two groups.​
Experimental and control group participants were matched on age, handeness and sex.​
Average age range 44​

50
Q

Kuhn

A

Kuhn et al. found a significant increase in grey matter in various regions of the brain after participants played video games for 30 minutes a day over a two-month period.

51
Q

davidson

A

Davidson et al. demonstrated the permanent change in the brain generated by prolonged meditation: Buddhist monks who meditated frequently had a much greater activation of gamma waves (which coordinate neural activity) than did students with no experience of meditation. ​

52
Q

Elbert et al

A

concluded that the capacity for neural reorganisation is much greater in children than in adults, meaning that neural regeneration is less effective in older brains. For example, young patients with stroke injury have been found to recover more successfully compared to old patients. ​
This may explain why adults find change more demanding than young people. Therefore, we must consider individual differences when assessing the likelihood of functional recovery in the brain after trauma.​

53
Q

speedy and gazzaniga aim

A

the aim of their research was to examine the extent to which the two hemispheres are specialised for certain functions.

54
Q

sperry and gazzaniga methods

A

An image/word is projected to the patient’s left visual field (which is processed by the right hemisphere) or the right visual field (which is processed by the left hemisphere).​
When information is presented to one hemisphere in a split-brain patient, the information is not transferred to the other hemisphere (as the corpus callosum is cut).​

55
Q

three different experiment of sperry and gazzaniga

A

 In the describe what you see task, a picture was presented to either the left or ​
right visual field and the participant had to simply describe what they saw. ​
 In the tactile test, an object was placed in the patient’s left or right hand and they ​
had to either describe what they felt, or select a similar object from a series of ​
alternate objects.​
 Finally, in the drawing task, participants were presented with a picture in either ​
their left or right visual field, and they had to simply draw what they saw.

56
Q

rogers et al

A

capacity (the ability to perform multiple tasks simultaneously). Rogers et al. (2004) found that in a domestic chicken, brain lateralisation is associated with an enhanced ability to perform two tasks simultaneously (finding food and being vigilant for predators). Using only one hemisphere to engage in a task leaves the other hemisphere free to engage in other functions. This provides evidence for the advantages of brain lateralisation and demonstrates how it can enhance brain efficiency in cognitive tasks.​

57
Q

turk et al

A

discovered a patient who suffered damage to the left hemisphere but developed the capacity to speak in the right hemisphere, eventually leading to the ability to speak about the information presented to either side of the brain. This suggests that perhaps lateralisation is not fixed and that the brain can adapt following damage to certain areas.​

58
Q

szaflarki

A

found that language became more lateralised to the left hemisphere with increasing age in children and adolescents, but after the age of 25, lateralisation decreased with each decade of life. This raises questions about lateralisation, such as whether everyone has one hemisphere that is dominant over the other and whether this dominance changes with age.​
