Evaluate the repeatability of psychological research

This paper is not to study new things, but many university researchers selected 100 psychological studies published in the Journal of Advanced Psychology in 2008, and then did all these studies again to test whether these studies are repeatable.

In this psychological study of 100, which was redone by researchers, most of the experimental evidence obtained is not as sufficient as the original experiment ("most of them are repeated.

Produced weak evidence.

Original discovery "), the author points out that the combination of incomplete experimental design and the tendency of psychological journals to publish positive results will easily lead to inaccurate research and low repeatability. The author also points out that the tendency to pursue novel topics in psychological research will also lead to research bias.

The interesting point of this paper is that the principle of repetition is one of the most important principles in empirical science, while the object of psychological research is human behavior, and people are not purely rational, and some research results cannot be perfectly reproduced. The "scientific nature" of psychology has also caused a lot of controversy and discussion. This article is actually a test of the reliability of the whole field of psychological research, and this paper itself can be regarded as "eye-catching".

Effective rehabilitation measures for patients with craniocerebral injury

Craniocerebral injury (TBI) is an area that has not been well studied at present, but millions of people suffer long-term or even permanent functional damage due to TBI in the United States alone. Archives of Physical Medicine and Rehabilitation is devoted to the research paper on TBI in August this year. Although the current rehabilitation situation depends more on the severity of the injury than the specific treatment methods, the study found that rehabilitation treatment can effectively help patients recover their functions and lead a normal life.

Another interesting study found that if you are female or Asian, the chances of doctors prescribing psychotropic drugs for you will decrease.

3. Best Friends and Better Coping: Promoting Resilience through the Closest Friendship between Boys and Girls, from the British Journal of Psychology.

Best friends can help you cope with difficulties better: the close friendship between boys and girls can promote the development of psychological resilience (I don't know that Chinese is equivalent to "psychological resilience", but this word refers to people's ability to deal with pressure and difficulties).

This study points out that even a benign friendship can promote low-income families or individuals with low social background to develop psychological resilience and get out of the predicament. The subjects were 409 British teenagers, aged 1 1- 19. Many previous studies have linked coping with difficulties and challenges with friendship, peer contact and family factors, but this paper focuses on the relationship between "best friends" and coping with difficulties, which is considered as a research progress.

4. "Non-drug treatment of long-term painful insomnia", from Sleep.

Non-drug treatment of chronic painful insomnia

This paper introduces and analyzes a series of non-drug therapies for insomnia. Among them, there are very traditional psychological education and sleep hygiene) Eg: Dimming the lights before going to bed can make the body produce melatonin, relax muscles and stimulate control.

Others help relieve insomnia through telephone and internet therapy, but research shows that the effect is not as good as face-to-face treatment.

Insomnia is a problem that puzzles many people, and sleep is also a very important research topic in psychology, so this systematic review of non-drug treatment of insomnia is also very meaningful.

5. The mechanical connection between sense of smell and autism spectrum disorder, Contemporary Biology.

The relationship between sense of smell and autism

Because autism is related to the damage of sensory-motor coordination system, the hypothesis put forward in this paper is that the olfactory response of autistic children will change (but the olfactory response will not), and it is related to the severity of autism and the social ability of autistic patients.

The significance of this discovery is that the diagnosis of autism is relatively difficult at present, especially for young children. Now we know the correlation between the sense of smell and autism, and the olfactory response can be used as the basis for diagnosing autism.

Autism research: more evidence shows that intestinal bacterial changes are related to autism

6. "Fibroblast growth factor 9 is a new negative effect regulator," from PNAS.

The relationship between FGF9 and emotional management

This article is about some new findings about the pathology of depression. FGF9 is a neurotrophic factor. This study found that FGF9 seems to play an important role in emotional control and management. According to the long-term pressure of animals being defeated or losing their group status, FGF9 will increase in hippocampus, while FGF9 is over-expressed in patients with major depression. This study also provides some new directions for us to think and study the pathology of depression, about which we know little.
