DEVELOPMENT OF SOCIAL COGNITION To read up on the development of social cognition, refer to pages 358–374 of Eysenck’s A2 Level Psychology. Ask yourself Why can’t very young children play hide-and-seek properly? How much do young children understand of other people’s thoughts and feelings? Do animals have any self-awareness? What you need to know THEORY OF MIND What it involves Its relation to autism SELMAN’S PERSPECTIVE- BIOLOGICAL TAKING THEORY EXPLANATIONS OF SOCIAL COGNITION Description, research findings, evaluation Mirror neuron system THEORY OF MIND The development of a sense of self and, alongside that, of understanding other people’s point of view is crucial to social development. This can be explained by Theory of Mind, which involves: The realisation that other people have beliefs, thoughts, and emotions that are different from our own. The appreciation of the beliefs, desires, intentions, and emotions of other people. The Theory of Mind is important in learning by imitation and for social interaction. It develops gradually: it is absent in most 3-year-olds and present in most 5-yearolds, so it develops around 4 years of age. The false-belief task is a way of assessing whether someone has a Theory of Mind. This is done by using tasks like “Sally–Anne”. Sally puts her marble in the basket. Then she goes out. Anne takes Sally’s marble, and puts it into her box. Then Sally comes back from her walk and wants to play with her marble. Where will she look for her marble? We will consider two explanations of how children develop a Theory of Mind: 1. Shared attention mechanism: Baron-Cohen (1995; see A2 Level Psychology page 363) argues that children combine information from their own direction of gaze with that of other people. Once children are able to use this mechanism they can understand that another person can see the same object as they can, and, importantly, that the second person can understand that they can see the object. 2. Language development: Astington and Jenkins (1999; see A2 Level Psychology page 360) argue that language development is crucial to a child’s development of Theory of Mind. RESEARCH EVIDENCE O’Neill (1996; see A2 Level Psychology page 360) found evidence that Theory of Mind may develop earlier than 4 years. It was shown that 2-year-olds are aware of whether or not their parents know where an attractive toy is hidden. Charman et al. (2000; see A2 Level Psychology page 360), using a longitudinal design, found that children who, at 20 months, had a lot of “shared attention” with an adult were good at Theory of Mind tasks 2 years later. This supports Baron-Cohen’s hypothesis concerning the shared attention mechanism. Lohmann, Carpenter, and Call (2005; see A2 Level Psychology page 360) found that children with better language ability were more proficient at false-belief tasks than those with lower ability. Astington and Jenkins (1999; see A2 Level Psychology page 360), in a longitudinal study, found that language ability predicted ability on Theory-ofMind tasks. This, as well as the previous study, supports Astington and Jenkins’ suggestion on the role of language in developing Theory of Mind. Autism Autism is a condition characterised by poor social interaction, impaired communication, and repetitive patterns of behaviour. Baron-Cohen maintains that the central problem with autism is failure to develop a Theory of Mind. This accounts for why autistic people cannot understand other people, and this impairs communication and social interaction. Baron-Cohen refers to this as “mindblindness”. He believes the inability to develop Theory of Mind is due to a lack of shared attention mechanism. RESEARCH EVIDENCE Baron-Cohen et al. (1995; see A2 Level Psychology page 362) used the Sally– Anne tasks on typical 4-year-olds, those with autism, and those with Down’s syndrome. They found that 80% of typical and Down’s children could do this correctly but only 20% of the autistic children. Happé (1995; see A2 Level Psychology page 362) found that even when autistic children succeeded in doing the Sally–Anne test, they did it in a very painstaking way, which seemed to indicate that it was not an ability that came to them automatically (as in a typical child). Baron-Cohen (1989; see A2 Level Psychology page 362) found that, on a more complex Theory-of-Mind task, 90% of typically developing 7- to 8-years-olds could solve the problem correctly whilst none of the autistic children of a higher mean age could. Baron-Cohen et al. (1996; see A2 Level Psychology page 363) tested 16,000 18-month-olds on tasks of shared attention and found that nearly all the 12 children who failed it were diagnosed with autism at 42 months. Dawson et al. (2004; see A2 Level Psychology page 363) found that autistic children have difficulties with aspects of attention and that these are worst with shared attention tasks. Frith and Happé (1994; see A2 Level Psychology page 363) found that autistic children lack central cohesion—the ability to take all aspects of a situation into account. For example, if someone makes a seemingly unkind remark whilst smiling, the autistic person does not appreciate that they are joking; only the remark, not the smile, is taken into account. Evaluation of Theoretical Approach to Theory of Mind It has shown the importance of Theory of Mind in communication. There is support for the concept of Theory of Mind. There is now such a wide body of research support for this concept that it has become accepted as an indisputable part of a typical child’s cognitive development. Some aspects of cognitive development associated with Theory of Mind have been identified. Language seems particularly important. It has contributed to our understanding of the difficulties involved in autism. One in particular is the shared attention mechanism. Its importance may be exaggerated. The false beliefs tasks are quite complex (note that this is not the same as difficult—the tasks test a lot of cognitive abilities). It is not clear how much a failure to achieve this demonstrates a lack of Theory of Mind as opposed to a lack of more general abilities. Motivational factors may better explain the findings. Baron-Cohen emphasises that autistic children don’t understand other people’s emotions because they do not have Theory of Mind. However, it’s possible that other limitations are involved, which result in the autistic child having no motivation to understand other people’s intentions. Autistic children may have deficits other than Theory of Mind. There is evidence that autistic children don’t just lack Theory of Mind but that they have other cognitive deficits, e.g. in central coherence. Theory of Mind does not account for all problems associated with autism. It is difficult to see how it can account for features such as obsessive behaviours, some language problems, and “islets of ability”. SELMAN’S PERSPECTIVE-TAKING THEORY Selman (1976, 1980) states that in order to understand other people and to have good social interaction, you need to be able to take their perspective. It is therefore similar to Baron-Cohen’s Theory of Mind. Being able to take another’s perspective means that you can negotiate better with people and be effective in solving interpersonal conflicts. The theory states that children go through the following stages in perspective taking: Level Age Features 0 3–6 Some recognition that other people can have different thoughts and feelings but no clear distinction between their social perspective (thoughts and feelings) and that of other people. 1 6–8 Some recognition that other people have access to different information and that this can produce different perspectives from their own. However, they generally focus on just one perspective rather than coordinating perspectives. 2 8–10 They can “step into another’s shoes”. They realise that mentally putting oneself in someone else’s place is an effective way of working out their intentions and likely actions. 3 10–12 Can understand that they and the other person can mutually and simultaneously adopt each other’s roles. They can move outside the twoperson interaction and view it mentally from the perspective of a third person. 4 12–15 Realise that mutual perspective taking is not guaranteed to lead to full understanding. They respect social convention as important because these conventions are understood by everyone and help to increase mutual understanding. Selman argues that good perspective taking is essential for good social interaction but does not guarantee it. This also requires knowing what behaviour is appropriate in a given situation. Good perspective taking is therefore a necessary but not a sufficient condition of harmonious social relationships. RESEARCH EVIDENCE Gurucharri and Selman (1982; see A2 Level Psychology page 366), in a longitudinal study, found that all the children showed some advance in interpersonal understanding over a 5-year period. Selman et al. (1983; see A2 Level Psychology page 366) found that girls who showed superior perspective-taking skills tended to communicate more effectively than other girls. Yeates et al. (1991; see A2 Level Psychology page 366) showed that scores on perspective taking were positively correlated with social competence and negatively correlated with behaviour problems. Burack et al. (2006; see A2 Level Psychology page 367) found that children from chronically dysfunctional families were worse on perspective-taking abilities than children brought up in well functioning families. Walker (1980; see A2 Level Psychology page 367) found a correlation between perspective-taking ability and Piaget’s stages of cognitive development. Since this is correlational, it is difficult to say which way the cause and effect lies but since most children reach the Piagetian stage before the Selman stage it indicates that perhaps one needs a certain level of cognitive ability before one can take the perspective of another person. Yeates, Schultz, and Selman (1990; see A2 Level Psychology page 367) found a reasonably strong positive correlation between IQ and perspective taking. Evaluation of Selman’s Perspective-taking theory The theory has successes to its credit: It has shown that children’s increasing ability to take the perspective of other people into consideration is important in their social development. The development of perspective taking proceeds through the stages identified by Selman. Perspective taking is associated moderately strongly with various aspects of social <i>behaviour<i>. This is important as the theory should be able to predict how perspective taking is related to actual behaviour. The poor perspective-taking abilities of maltreated children may help to explain why they lack social skills and interpersonal sensitivity. The rate of development in perspective taking is predicted by children’s cognitive development and IQ. Perspective taking is not the full story. Although cognitive factors are important, there are some children with good abilities in this respect but who are not very adept at social interaction because they lack motivation to use these abilities. It does not explain how children pass through the stages. It describes the stages but does not account for factors that move children through these stages. Many findings are correlational, so cause and effect are not clear. It de-emphasises individual differences in personality. It is concerned with the stages each child goes through but cannot fully account for individual differences in doing this. BIOLOGICAL EXPLANATIONS OF SOCIAL COGNITION Mirror Neuron System The mirror neuron system is a part of the brain believed to help us understand the actions of other people. Gallese et al. (1996; see A2 Level Psychology page 369) labeled a set of neurons in the F5 area of the premotor cortex as the “mirror neuron system”. It consists of neurons that are activated when animals perform an action and when they observe another animal perform the same action. The mirror neuron system, therefore, is believed to be concerned with understanding the behaviour and emotional states (hence the intentions) of others and may underlie the Theory of Mind. As the research indicates, this system is present in monkeys. Whether or not it exists in humans, as well as its precise functions, is still uncertain. RESEARCH EVIDENCE Umiltà et al. (2001; see A2 Level Psychology page 370) demonstrated that monkeys can understand the meaning of actions, not just the actions, and that mirror neurons are discharged only when the monkey may want to imitate the behaviour (e.g. in order to get food), not when they wouldn’t (because there is no food there). Dinstein et al. (2007; see A2 Level Psychology page 370) showed that five brain areas were activated when the same movement was being observed repeatedly as when that movement was actually being made repeatedly. However, it is not yet clear whether the same neurons were being activated or different neurons that were in the same part of the brain. Iacoboni et al. (2005; see <i>A2 Level Psychology<i> page 370) provided evidence that the mirror neuron system in humans (if it exists) may be involved in understanding the intentions behind observed actions because it only seems to operate when it is obvious <i>why<i> a person is performing a particular action. EVALUATION OF THE MIRROR NEURON SYSTEM Evidence that the mirror neuron system plays an important role in social cognition. As discussed above, there is research supporting this, especially that the mirror neuron system plays a part in understanding other people’s intentions and actions. Evidence that the mirror neuron system takes account of the context of an action. Umiltà et al.’s research demonstrates this. Impairments in the mirror neuron system may help to explain the problems associated with autism. This is speculative at present but offers insightful hypotheses for further research. Brain imaging is not very precise. fMRI scans are not sufficiently detailed enough to identify clearly what is happening at the level of individual neurons. The mirror neuron system does not take personality into account. When we assess intentions, we take account of stable personality characteristics of the person (e.g. Anne is smiling because she’s friendly; Clare is smiling because she wants something from me). There is no evidence that the mirror neuron system can account for how we do this. Limits on generalisation. Most information on the role of the mirror neuron system has come from monkeys so the findings cannot necessarily generalise to humans brains. Monkeys are far less skilful at inferring intentions. The relationship between the mirror neuron system and autism is not clear. We are unclear of cause and effect: does autism result from an impaired mirror neuron system or is an impaired mirror neuron system the result of autism (see research below)? Emotional States The mirror neuron system may be involved in our ability to experience and understand emotional states in others. Philips et al. (1997; see A2 Level Psychology page 371 ) showed that the same part of the brain (part of the limbic system in the brainstem) is activated when people experience disgust as when they see a facial expression showing disgust. This indicates that the human mirror neuron system is responsive to emotional states. Again, though, it’s not clear if the same neurons are activated or just the same area of the brain. Autism There is evidence relating to the role of the mirror neuron system in autism: Dapretto et al. (2006; see A2 Level Psychology page 371) found less activity in the mirror neuron system of autistic children than in non-autistic children when observing or imitating five basic emotions (e.g. happiness, anger, fear). This indicates that autistic children have impaired mirror neuron systems. Whether this causes the autism or is a consequence of it is, as yet, unclear. Hadjikhani et al. (2006; see A2 Level Psychology page 372) found that autistic children have cortical thinning in areas of the brain believed to form part of the mirror neuron system. Rogers et al. (2003; see A2 Level Psychology page 372) found that autistic children’s ability to imitate was not related to their language development or their adaptive behaviour. This indicates that the mirror neuron system is not central to autistic children’s difficulties. Dinstein et al. (2008; see A2 Level Psychology page 372) found that in at least half of a series of observation and imitation tasks autistic children had similar brain activity as non-autistic children in areas associated with the mirror neuron system. This again questions whether the mirror neuron system is central to the autistic condition. So What Does This Mean? Great strides have been made in recent years on factors underlying the very fundamental ability of acquiring a sense of self and of understanding other people’s perspective. This has, in turn, led to greater understanding of autism. Both the Theory of Mind and the Theory of Perspective Taking offer insight into some of the impairments involved in this condition. They have certainly furthered our knowledge of why so many autistic people find social interaction so challenging. Nonetheless, some puzzles remain. Certain features of autism, such as obsessional behaviour, the intolerance of change, and certain language deficits are hard to explain in terms of these theories. Most of all they cannot account for the amazing talents that a small number of autistic people demonstrate. The biological contribution to this field of study has offered enlightenment that has enhanced our understanding still further. Work on the mirror neuron system, although in its infancy, has opened the possibility of exciting new research that underpins and complements the work on the psychological processes involved in our ability to engage in social interaction and provide us with a sense of our place in society. Over to you Describe and evaluate one or more theories that seek to account for the development of perspective taking in children. (25 marks)
