Autism is a profound disorder that affects physical, social, and language skills. The term itself refers to a state of increased self-absorption, which seems to go along with language problems and problems in developing normal social relationships, shown by reluctance to engage in physical contact or displays of affection. There are also difficulties in developing normal social attachments to significant adults in the child's life, though there can also be very strong attachments developed to particular objects. Other symptoms can involve compulsive body movements such as rocking, limited reactions to sound or pain, and a strong desire to maintain a particular environment (with great distress shown at the possibility of change). 
Own travel. Certainly, travel is more than the seeing of sights; it is a change that goes on, deep and permanent, in the ideas of living. Miriam Beard. It is often said that travel broadens the mind, but it can also influence the development of psychological theory. For instance, Darwin's travels in South America and the Galapagos Islands are closely associated with his later theory of natural selection. Similarly, William James' travels around Europe allowed him contact with a body of psychological thought (both experimental and psychodynamic) quite different from the tradition developing in the United States. Travel also suggests permanent movement from one country to another. The impact of the movement of psychologists from mainland Europe to the UK and the USA during and following the second world war is discussed in the World War II entry. However, the experience of migration in itself can provide new insights into one's own identity, cultural and social differences and can highlight how we understand ourselves as a member of a specific group or social category. For instance, in developing the information for EPoCH we asked “Has your work been influenced by any historical/cultural/social contexts”. Csikszentmihalyi replies that: Moving from one culture to another (Hungary/Italy/the United States, with many side-trips elsewhere) has been very helpful in relativizing my beliefs, while impressing on me the fundamental similarities among human beings”\n\nWetherell, in reply to the same question states: \n\nI have been influenced by my status as a migrant to Britain and growing up in an ex-colony (New Zealand).

Dyslexia. Someone with dyslexia has normal intellectual abilities, apart from a particular inability (or great difficulty) in learning to read or spell. Dyslexia seems to be a neurological disorder, inhibiting an individual's capacity to recognize and process symbols such as letters (and sometimes also numbers). Although the origins of dyslexia are far from clear, it does occur within particular families, which could point to possible genetic contributions. Dyslexia is also found much more commonly in boys than girls (by a ratio of three to one).\nThe main symptom usually emerges in early schooling, involving very poor reading skills in an otherwise bright child with no apparent problems apart from this. Other symptoms can involve reversals of words/letters in the process of reading or writing, which seems to be linked to significant difficulties in distinguishing left from right. This has led to speculation that the possible causes of dyslexia may lie in incomplete lateralization of the two brain hemispheres (see HEMISPHERIC ASYMMETRIES), although no clear evidence has yet emerged in this respect.
