Recently some studies have been influenced by an evolutionary psychology perspective.[45] This includes studies on testosterone changes in sports which at least for males are similar to those in status conflicts in non-human primates with testosterone levels increasing and decreasing as an individual's status changes. A decreased testosterone level may decrease dominant and competitive behaviors which when the status conflicts involved fighting may have been important for preventing physical injury to the loser as further competition is avoided.[citation needed] Testosterone levels also increase before sports competitions, in particular if the event is perceived as real challenge as compared to not being important.[citation needed] Testosterone may also be involved in the home advantage effect which has similarities to animal defense of their home territory.[citation needed] In some sports there is a marked overrepresentation of left-handedness which has similarities to left-handed likely having an advantage in close combat which may have evolutionary explanations.[citation needed]
"It is my belief that psychotherapy has the best chance to be effective when the client and therapist have a strong therapeutic alliance. That is, they have a good working relationship and are working toward exactly the same goals using methods or approaches best suited for the client. I strive to achieve this by providing a warm and safe climate, listening closely to the needs of my clients, and discussing our options and strategies."

Most organizations believe that once someone reaches executive or senior status in the organization, they should inherently be able to act under pressure, inspire and implement ideas, keep their skills sharp and current, and have all the answers. In actuality, they can eventually get there on their own but the engagement of a qualified executive coach will exponentially increase not only the time it takes for the executive to get there but also the ability for the executive and the company to sustain the change.

Griffith opened an athletic research laboratory at the University of Illinois in 1925. In 1925 he published an article, 'Psychology and Its Relation to Athletic Competition,' which is considered one of his most important works/writings. He also published a couple of textbooks, namely Psychology of Coaching and Psychology and Athletes. Griffith's progress was stunted when his lab was shut down in 1931 at the beginning of the Great Depression.
With the growing popularity of coaching, many colleges and universities now offer coach training programs that are accredited by a professional association.[31] Some courses offer a life coach certificate after just a few days of training,[32] but such courses, if they are accredited at all, are considered "à la carte" training programs, "which may or may not offer start to finish coach training," according to the ICF.[33] Some "all-inclusive" training programs accredited by the ICF require a minimum of 125 student contact hours, 10 hours of mentor coaching and a performance evaluation process.[34][35] This is very little training in comparison to the training requirements of some other helping professions: for example, licensure as a counseling psychologist in the State of California requires 3,000 hours of supervised professional experience.[36] However, the ICF, for example, offers a "Master Certified Coach" credential that requires demonstration of "2,500 hours (2,250 paid) of coaching experience with at least 35 clients"[37] and a "Professional Certified Coach" credential with fewer requirements.[38] Other professional bodies similarly offer entry-level, intermediate, and advanced coach accreditation options.[39] Some coaches are both certified coaches and licensed counseling psychologists, integrating coaching and counseling.[40]
Some sport psychologists might also work closely with once enthusiastic athletes that have suffered injuries as well. Depending on the severity of the injury, a sport psychologist may attempt to help a recovering athlete segue back into his career with as little stress as possible. Some athletes don't have this choice, however, and they may need the help of a sport psychologist to help them deal with the fact that they may not be able to play their sport with as much talent and drive as they had at one time.
Salaries vary based on the psychologist's area of specialization and experience, the employing organization and the amount of advanced training received. Experienced psychologists working for professional sports teams or professional athletes may earn six-figure salaries, while those working in educational or research settings receive more modest salaries.
Hypnosis might not be appropriate for a person who has psychotic symptoms, such as hallucinations and delusions, or for someone who is using drugs or alcohol. It should be used for pain control only after a doctor has evaluated the person for any physical disorder that might require medical or surgical treatment. Hypnosis also may be a less effective form of therapy than other more traditional treatments, such as medication, for psychiatric disorders.
Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
