Sex Differences in Intelligence Areas and Response Time
Tasks, is a research paper by Natalie Bennett, conducted in 2011, where certain
Response Time Tasks with various levels of complexity were conducted and the
participants’ performance was recorded. Thirty five students participated in
the same.

In the first part of the study, in order to obtain IQ
estimates, the Wechsler Adult Intelligence Scale IV (WAIS-IV) was administered.
In research previously conducted, results showed that females outperformed
males in verbal ability and perceptual speed WAIS-IV subtests and the same was
hypothesized for this research.

In the second part of the study, participants were required
to complete four response time (RT) tasks, each of a different level of
complexity. The author, upon reviewing past literature and from previous
observations, reached two hypotheses- the first one: the males undertaking the
tests would outperform the female participants on the signal detection task
(which is the simplest of the four RT tasks); and the second: the females would
be able to outperform the male participants on the lexicon decision task
(reliant on verbal ability)

The study results help the authors conclude that males did
indeed have faster RTs than females in the signal detection task. Furthermore,
it was also concluded that male and female RTs on this signal detection task
correlated differently with the subtests of the WAIS-IV. However, there were no
sex differences found on any of the other three RT tasks. Furthermore, no sex
differences were found on any subtests of the WAIS-IV.  Thus, these findings highlight the fact that
although sexdifferences  not mandatorily
be obvious in intelligence or RT performance, it can be inferred that males and
females may use different resources to complete the same task

A fairly common notion prominent in today’s academic circles
is that there exists no (or minimal) sex differences in the characteristic of
intelligence.  However, this view is
contradicted by Lynn (1994, 1999) in his Developmental Theory of Sex
Differences in Intelligence. The theory states that maturity levels of boys and
girls are inherently different; the growth of girls accelerates from the age of
9, staying ahead of boys until about 14-15 years. However, from this age, the
growth of girls slows down as compared to boys. As boys continue to grow from
this age their height and their mean IQs increase relative to those of girls.
The paper collects new data from the Spanish standardization sample of the
fifth edition of the DAT. A total of 1027 boys and 924 girls from ages 12-18
years were tested. The theory was supported as it was found that younger girls
perform better than boys and this difference in performance decrease with age.
There is a 4.3 IQ advantage for the 18 year old boys in the DAT as a whole,
which is very close (4.4 IQ points) to the benefit that can be expected from
their larger brain size. The similarity within the sex difference s in
abilities between the Spanish sample and that in the United States and Britain
is testimony to the robustness of the difference in these different cultures.

 

 

both claimed the same. The view that women are intellectually
inferior came from early researches that used volume and size of the brain as
factors of intelligence. Once it was found to not be a factor the view slowly
shifted. In 1916, Lewis Terman concluded that “the
intelligence of girls, at least up to 14 years, does not differ materially from
that of boys”.

A number of studies have been conducted and
have brought about mixed results.

Individuals differ from one another in their ability to understand
complex ideas, to adapt effectively to the environment, to learn from
experience, to engage in various forms of reasoning, to overcome obstacles by
taking thought. It has been long debated whether or not intelligence differs
between the sexes. Numbers of researches have shown that ‘g’ or general intelligence
remains the same between the two sexes. These studies are extremely important
and relevant to psychologists because if there exists differences in intelligence
between the sexes, they can be applied in various aspects and help simplify and
factorize and segregate daily activities such as driving, athletics, driving
etc. according to their sexes.   The argument of whether or not there is an
advantage for men when it comes to intelligence still remains, despite of the
findings of these researches.

Right up to the early 20th century
it was widely held view that men had greater intellect than women. Herbert Spencer
