Goals Of Psychological Studies

Psychologists have accepted scientific method and try to generate knowledge which stands well on the above mentioned criteria of science. As scientists they try to achieve the following goals regarding the objective of their study. 

1. Description: The first step towards gaining understanding is to obtain a proper or systematic description of the phenomenon under study. It determines the range and boundary of the phenomena. 

2. Explanation: Explanation means statement of the factors which determine the phenomenon under study. In other words, one may say that explanation provides the factors which make something happen. Thus, when a psychologist shows that practice leads to change in behavior he or she is explaining learning. 

3. Prediction: Once we are able to get the explanation of some phenomena we are in a position to tell or predict what will happen under certain circumstances. The ability to make prediction is based on systematic analysis of the various causal factors. The presence or absence of those factors can help one to tell what will happen in future. 

4. Control: The ability to predict provides the knowledge necessary to bring the change that is desirable. For instance, use of polio vaccine prevents the occurrence of polio. Similarly practicing yoga or relaxation can be used to improve health and quality of life of the people. Thus knowledge can be used to produce results desired by the user of knowledge. This, however, is possible only when we have scientific knowledge.

ocean currents and their impacts on marine life and coastal environment

Image
Its physical characteristics like temperature, salinity, density and the external forces like the sun, the moon and the winds influence the movement of ocean water. Ocean currents are the continuous flow of huge amount of water in a definite direction. Water moves ahead from one place to another place through ocean currents. Ocean currents have direct impact on the climate and economy of the region.  Ocean currents and water masses differ in their impacts on marine life and the coastal environment in different ways:  • Impact on biodiversity:  The physical parameters of water masses are essential because they structure the water masses and determine the various habitats that provide the environmental conditions required for marine life.  These conditions influence the production and the growth of plankton and fish species. The dispersion and dwelling of larvae for many benthic and pelagic species depend on hydro-graphical factors. They also play an important role for...

Hubble Space Telescope Fast Facts

Image
The Hubble Space Telescope explores the universe from Earth orbit. This vantage point allows it to obtain a view of cosmic objects unobstructed by Earth's atmosphere, which can distort light and block certain wavelengths.   NASA named Hubble after American astronomer Edwin P. Hubble (1889–1953). Hubble confirmed an "expanding" universe, which provided the foundation for the Big Bang theory. Mission Launch: April 24, 1990, from Space Shuttle Discovery (STS-31) Deployment: April 25, 1990 First Image: May 20, 1990: Star cluster NGC 3532 Servicing Mission 1 (STS-61): December 1993 Servicing Mission 2 (STS-82): February 1997 Servicing Mission 3A (STS-103): December 1999 Servicing Mission 3B (STS-109): February 2002 Servicing Mission 4 (STS-125): May 2009 Size Length: 43.5 feet (13.3 m) Weight (at launch): about 24,000 pounds (10,800 kg) Weight (post-SM4): about 27,000 pounds (12,200 kg) Diameter (at widest point): 14 feet (4.3 m) Spaceflight Stati...

The Hubble Space Telescope, NASA

Image
Named in honor of the trailblazing astronomer Edwin Hubble, the Hubble Space Telescope is a large, space-based observatory, which has revolutionized astronomy since its launch and deployment by the space shuttle Discovery in 1990. Far above rain clouds, light pollution, and atmospheric distortions, Hubble has a crystal-clear view of the universe. Scientists have used Hubble to observe some of the most distant stars and galaxies yet seen, as well as the planets in our solar system. Hubble’s capabilities have grown immensely in its over 30 years of operation. This is because new, cutting-edge scientific instruments have been added to the telescope over the course of five astronaut servicing missions. By replacing and upgrading aging parts, these servicing missions have greatly extended the telescope’s lifetime. Telescopes have a particular range of light that they can detect. Hubble’s domain extends from the ultraviolet through the visible (which our eyes see) and into the near-infrared....

The Reforms of 1909 & Controversy of Indian Electoral System

In 1909, the government introduced some constitutional reforms in Indian, to please the moderate leaders and strengthen their position in the congress. These reforms are named after Morley, the secretary of the state for India, who piloted the bill through the British Parliament. Though it was the first true attempt at introducing a representative and popular element, it was not free from flaws. The real aim of the reforms was to divide the nationalist ranks and to check the growth of unity among Indians.  The reforms introduced the system of separate electorate, under which all the muslims were gathered in separate constituencies from which only muslim candidates could be elected. It was claimed to have been done to protect the muslim minority. But in reality the reforms was an attempt to divide the Hindus and Muslims, to strengthen British supremacy in India by checking the growth of national unity in India.  However, it may be said that the reforms set the stage for the ado...

India’s plan to have its own space station and how will it benefit our space programme

Image
Space station is also called orbital station. It orbits around Earth. Basically, it is a large spacecraft or man-made station in space, a home where astronauts live. It also receive several space crafts from the Earth. It is a kind of science lab, many countries worked together to build it and also, work together to use it. Recently ISRO chief said ‘We are planning to have a separate space station. We will not be a part of ISS. Our space station is going to be very small’.  India’s plan to have its own space station  •The Indian space station will be much smaller (mass of 20 tonnes) than the International Space Station and will be used for carrying out micro gravity experiments (not for space tourism).  •Preliminary plan for the space station is to accommodate astronauts for upto 20 days in space, and the project will be an extension of the Gaganyaan mission.  •It will orbit the Earth at an altitude of around 400km.  •ISRO (Indian Space Research Organisation) is...

Why is India taking keen interest in resources of Arctic Region

Image
The Arctic region refers to the polar region north of the Arctic Circle. This region has assumed significance in light of the increasingly visible impact of global warming and its increasing geo-strategic significance.  Salience of the Arctic region for India :  • Potential Natural Resource : The region is said to posess large reserves of oil and natural gas which can solve the problem of energy security for India, especially with West Asia in turmoil. It is also an abundant source for fisheries.  • Newer Shipping Routes : As global climate warms up and polar ice recedes, new paths between Asia, Europe and North America open up, which can reduce time and costs for India’s imports and exports.  • Strategic Importance : China’s assertiveness and its ability to navigate the Northern Sea Route needs to be factored in while formulating India’s military strategy for the region.  • Research on Environmental Issues : Joint research may be conducted in the following s...
