It's theorized that there is a Critical Period of language development in children below the age of five (roughly, as age ranges always are in Developmental Psychology). Probably the most significant and readily verifiable finding is that a critical period exists for the learning of Phonemes. Research has suggested children readily differentiate phonemes ...

Wikipedia on time perception The Wikipedia article on "time perception". In particular, the section on long-term time perception cites a couple of articles. * The articles makes the common point that a unit of time as a proportion of one's life decreases with age. A few empirical studies are also cited. Ukraintseva (2001) Ukraintseva (2001) wrote an ...

As the Wikipedia article on Masturbation summarizes, the current consensus among scientists is that masturbation has no negative effects whatsoever, and that all known positive effects are physiological (e.g. reduction of the probability to have prostrate cancer in men over 50) or on the level of general well-being (e.g. it relieves depression and leads to ...

This effect is referred to as Piaget's Theory of Conservation. Piaget constructed an experiement where children would be shown a tall, narrow glass of colored water (to make it clearly visible in a clear glass) and two shorter, wider glasses of the same exact size. A single amount of water would be distributed in both small glasses. If a child is asked ...

There is "hard evidence" regarding how timing and the subjective experience of intervals changes as a function of age. McAuley et al. (2006) ran a battery of different timing and time perception tasks on participants of ages ranging from 4 to 95 years. One finding that relates to your question was that children in the range of 4 to 7 years preferred and, ...

I am by no means any sort of expert at the French mental health system, but I was curious and found a few reasons that may indicate why such a philosophy is prevalent. In this blog, an American psychologist analyzes the differences between the American and French schools of thought on ADHD, but the observations hold for other conditions as well. While ...

Seattle Longitudinal Study: You might want to have a read about The Seattle Longitudinal Study of Adult Intelligence. There's a summary of the study on this website. To quote the website: The Seattle Longitudinal Study of Adult Intelligence has followed a group of more than 5000 people for well over four decades. The program began in 1956 and ...

This is a partial answer suggesting a possible causal mechanism. One of the factors leading to birth defects and autism is mutations in the parent's genetic material. In a recently published article, Sun et al. (2012) observed that: The paternal-to-maternal mutation rate ratio is 3.3, and the rate in fathers doubles from age 20 to 58, whereas there is ...

It's possible to instill a false memory, even a traumatic one, in an adult. Children have been known to be more susceptible to suggestion since the 19th century (Binet, 1900, 1905). Here are some example references of memory implantation: Porter, S., Yuille, J. C., & Lehman, D. R. (1999). The nature of real, implanted, and fabricated memories for ...

Well, I have some few memories of my very early childhood, but it is undisputable (and the articles quoted by PEEJWEJ don't dispute it either) that most children don't remember most things from their earliest years. The number of events that adults remember from their childhood, and the memory span of a child, clearly increases with the age of the child: ...

Kramer et al 2008 is an excellent study of this question because it utilizes intervention, thus lending strength to the claim of causation, concluding that IQ was "significantly higher in the experimental group for both reading and writing". But is it the milk itself? Some argue that it's also the skin-to-skin contact, and the mother-child bonding. ...

Many parts of the fetus brain begin showing neural activity before the senses that feed them are sufficiently developed to provide actual sensory information. In other words, it is unlikely that spiking activity in the brain is initiated by the senses. Some of the cells that become sensory organs, however, often fire in very specific patterns similar to the ...

I don't know of any NN algorithms that match your definition entirely, and I have looked for them (previously and recently). Here are some papers that I think are close or in the direction that you are exploring. Using theoretical models to analyze neural development (review) An Instruction Language for Self-Construction in the Context of Neural Networks ...

A conscious basis for gender identification? There is currently no evidence to suggest that conscious experiences are a factor in leading a transgender person to identify with the opposite sex. Additionally, there is mounting evidence that transgender children are statistically indistinguishable from children of the gender with which they identify, meaning ...

The classic reference for exactly what you are describing is Gilovich & Medvec, 1995 (LINK), the primary thesis of which is that "Actions, or errors of commission, generate more regret in the short term; but inactions, or errors of omission, produce more regret in the long run" (from the abstract). The authors explain that there are many factors that ...

Heritability estimates of Extraversion (and other Big 5 factors) The introduction section of Loehlin et al (1998) provides a narrative review of heritability estimates of big 5 personality traits (i.e., one of which is extraversion). A brief extract gives a flavour of some of the research that has been conducted: A recent heritability analysis of the ...

A fetish is arousal from an inanimate/non-living/non-sentient object. They fall into two categories: media fetish (e.g., a fetish for leather, regardless of the form it takes), and form fetish (e.g., a shoe fetish, regardless of the material the shoe is made out of). There are multiple theories on how fetishes develop: Classical Conditioning - the ...

A useful model for topics like this comes from McCrae and Costa (1999): There's quite a lot more going on here than is pertinent to your question, but note that influences originate from biological bases on the top left, and from external influences on the upper right. Everything else is modeled as an effect of mediated, dynamic processes between these ...

For more recent work on false memories, look at this paper. The authors provide a biological basis for false memories. They also implant false memories in mice.

The preference for mother's voice over a stranger's voice has been show in utero by Kisilevsky et al. (2003) by measuring the fetus' heart rate. It increased in response to mother's voice and decreased in response to a stranger's voice compared to baseline. Kisilevsky and Hains (2011) followed up the earlier study, and determined that the onset of ...

To learn about other twins reared apart, investigate the earlier Minnesota Study of Twins Reared Apart and the ongoing Minnesota Twin Family Study. To pique your curiosity: Jim Lewis and Jim Springer stand out in the Minnesota Study of Twins Reared Apart because some of their two histories were strikingly identical; several notable examples: 1st wife: ...

It seems this "fact" is becoming more debatable. This article and this article might clear up some misconceptions and confusion about this issue. It's incredibly difficult to say anything about memory that applies to all situations. Each person will remember different things for different lengths of time, but often it is not based on some aspect of ...

This is an extremely interesting question. I'm going to take a different approach to the question by focusing on both personality traits and leadership theories (e.g. authentic leadership, transformational leadership, servant leadership etc) to answer whether those two distinct areas can influence leaders' children's development. I will admit that I didn't ...

The first one is a test if a child has understood conservation of matter. It is an example of a conservation task. These belong to the tests used in the framework of Piaget to test what stage of development a child is in. Here is a video demonstration of the cookie task. Here is another question on this site pertaining to a different conservation task. The ...

Pornography laws are a relic of the Victorian era, and not based on any science. Research that can conclusively determine the effect of pornography on children is hard to come by due to the resultant ethical environment. Most research depends on self-reports: Surveys ask adolescents how much pornography they have been exposed to, and attempt to correlate ...

For an introduction to neurotransmitters (and the field of neuroscience) a good book to start with is Principles of Neural Science (Kandel, Schwartz, and Jessel, 2000). It is a standard reference used by many undergraduate and graduate courses in neuroscience/related fields. The next edition is due for publication in October. During development ...

Another reason for reduced plasticity in adults is that learning something different in the presence of an existing knowledge structure is more difficult than learning from a "blank slate". In a sense, you get interference from the known language (for example). One person who has developed this argument computationally is Jay McClelland in the context of ...

Much evidence suggests children do not show as much top down processing as adults. This depends on your definition so I'll state that I generally mean that use of top-down processing appears to increase as a child develops. Here is the abstract explaining the results of the study Developmental increase in top-down and bottom-up processing in a phonological ...
