Q1Review Questions
Explain the nature of thinking.
Solution
Thinking is a complex and higher mental process that forms the base of all cognitive activities. It is unique to human beings and involves the manipulation and analysis of information received from the environment or already stored in our memory. The nature of thinking can be understood through the following characteristics:
- It is a Higher Mental Process: Thinking goes beyond simply receiving information. It involves creating new meaning by interpreting, relating, and analysing information, using processes like abstracting, reasoning, problem solving, and judging.
- It is Goal-Directed: Most of our thinking is organised and directed towards achieving a specific goal. Activities, from simple daily chores to complex problem-solving, involve planning and strategizing to reach a desired outcome.
- It is an Internal Process: Thinking is a mental activity that cannot be directly observed. It can only be inferred from a person's overt behaviour. For instance, we can infer a chess player's thought process by observing their moves on the board.
- It Uses Mental Representations: Thinking relies on knowledge we already possess, which is represented in the form of mental images (a mental representation of a sensory experience) or concepts (a mental representation of a category).
Q2Review Questions
What is a concept? Explain the role of concept in the thinking process.
Solution
A concept is a mental representation of a category. It refers to a class of objects, ideas, or events that share common properties. For example, the concept of 'fruit' includes apples, oranges, and bananas because they share common characteristics like being edible, growing on plants, and containing seeds.
The role of concepts in the thinking process is crucial for efficiency and organisation:
- Organising Knowledge: Concepts help us organise our vast knowledge in a systematic way, similar to how books are organised in a library. By categorising objects and events, we can structure our understanding of the world.
- Making Thinking Efficient: By forming concepts, we can process information quickly. When we encounter a new object, we match its characteristics with existing concepts to identify it. This allows us to make inferences and predictions without analysing every single detail. For instance, upon identifying a new type of dog, we can infer it might bark or wag its tail based on our concept of 'dog'.
- Reducing Cognitive Load: Concepts allow us to group individual items into a single mental representation. Instead of remembering the details of every single chair we have ever seen, we can use the concept of 'chair'. This simplifies our mental world and makes our thought processes less time-consuming and effortful.
Q3Review Questions
Identify obstacles that one may encounter in problem solving.
Solution
One may encounter several obstacles while trying to solve a problem. The two major obstacles discussed in the chapter are mental set and lack of motivation.
-
Mental Set: This is a tendency to solve problems by following already tried and tested mental operations or steps. While relying on past successful strategies can be helpful, it can also create mental rigidity. This rigidity obstructs the problem solver from thinking of new rules or strategies that might be more appropriate for a new problem. An example of this is functional fixedness, where a person is fixated on an object's usual function and fails to see its potential for other uses (e.g., not thinking of using a book as a hammer).
-
Lack of Motivation: A person may possess excellent problem-solving skills, but these are useless without the motivation to use them. People sometimes give up easily when they face a difficult problem or fail in their initial attempts. Persistence and effort are necessary to find a solution, and a lack of motivation prevents this.
Q4Review Questions
How does reasoning help in solving problems?
Solution
Reasoning is a form of goal-directed thinking that helps in solving problems by allowing us to gather and analyse information to arrive at logical conclusions. It is the process of drawing inferences from certain given information. Reasoning helps in problem-solving in the following ways:
-
Deductive Reasoning: This involves starting from a general assumption or rule and moving to a specific conclusion. In problem-solving, if we have a general principle we believe to be true, we can apply it to the specific problem at hand to deduce a solution. For example, if the general rule is 'all students in this class must submit the project', and 'Ram is a student in this class', we can deduce that 'Ram must submit the project'.
-
Inductive Reasoning: This involves moving from specific facts or observations to a general conclusion. When solving a problem, we can observe specific instances or gather data to identify a pattern or form a general rule that helps us find a solution. Scientists often use inductive reasoning by conducting multiple experiments to arrive at a general theory.
-
Analogical Reasoning: This involves identifying a relationship between two things and applying that same relationship to a new pair of things (A is to B as C is to D). Analogies can be very helpful in solving problems by helping us to identify and visualise important features of a problem that might otherwise be overlooked. They allow us to use the solution of a similar past problem to solve a new one.
Q5Review Questions
Are judgment and decision-making interrelated processes? Explain.
Solution
Yes, judgment and decision-making are highly interrelated processes. While they are distinct, one often leads to the other, and they work together in problem-solving and daily life.
-
Judgment: This is the process of drawing conclusions, forming opinions, and evaluating events or objects based on available knowledge and evidence. For example, based on a person's characteristics like being talkative and persuasive, we might judge them to be suitable for a sales job.
-
Decision-Making: This is the process of choosing among several available alternatives. In decision-making, we already know the various options, and our task is to select one.
The interrelationship lies in the fact that we use judgment to evaluate the alternatives before making a decision. When faced with a choice, we assess the costs and benefits associated with each option. This evaluation is a form of judgment. For instance, when deciding between studying psychology or economics, a student would use judgment to evaluate their interest in each subject, future career prospects, and the quality of teachers. Based on this judgment of the various factors, the student then makes a final decision. Therefore, judgment is a critical step in the process of decision-making.
Q6Review Questions
Why is divergent thinking important in creative thinking process?
Solution
Divergent thinking is crucial to the creative thinking process because it is the mode of thinking that allows for the generation of novel and original ideas. Creative thinking is defined by the production of ideas or solutions that are new and unique. Divergent thinking directly facilitates this through its open-ended nature.
Its importance can be understood through its key characteristics:
- Fluency: It is the ability to produce a large number of ideas for a given task. The more ideas generated, the higher the probability of finding a creative or original one.
- Flexibility: This refers to the variety in thinking, such as thinking of different uses for an object or different ways to solve a problem. Flexibility prevents rigid thinking and opens up new possibilities.
- Originality: This is the ability to produce ideas that are rare or unusual. Divergent thinking encourages seeing new relationships and looking at things from different perspectives, which are necessary conditions for originality.
- Elaboration: This is the ability to go into detail and work out the implications of new ideas.
While convergent thinking (which focuses on finding a single correct answer) is important for evaluating and selecting the best idea, it is divergent thinking that provides the raw material for creativity by generating a wide range of potential solutions and possibilities. Without the exploration of multiple, varied, and unusual ideas fostered by divergent thinking, the creative process could not begin.

How can creative thinking be enhanced?
Solution
Creative thinking is a potential that everyone has, and it can be enhanced by cultivating certain attitudes and using specific strategies. Some ways to enhance creative thinking are:
-
Increase Awareness and Sensitivity: One should become more aware and sensitive to the surroundings—noticing and responding to feelings, sights, sounds, and textures. This involves spotting problems, missing information, and contradictions that others might overlook. Cultivating a habit of wide reading, asking questions, and pondering mysteries can foster this sensitivity.
-
Generate Multiple Ideas: To increase fluency, one should practice generating as many ideas, responses, or solutions as possible for a given task. To enhance flexibility, one should deliberately look for multiple angles and perspectives on a situation. This could involve thinking of alternative arrangements of furniture in a room or different ways to deal with a conflict.
-
Use Brainstorming: Osborn's Brainstorming technique is a powerful tool. Its basic principle is to separate the production of ideas from their evaluation. Participants are encouraged to let their minds think freely and generate as many ideas as possible without any judgment. This focus on quantity over quality in the initial stage increases the fluency and flexibility of ideas and piles up alternatives from which a creative solution may emerge.
-
Overcome Mental Blocks: It is important to overcome blocks like mental set and functional fixedness that limit creative solutions. Deliberately trying new approaches and looking for unconventional uses of objects can help break these rigid patterns of thought.
Q8Review Questions
Does thinking take place without language? Discuss.
Solution
Yes, thinking can take place without language. While language is a primary vehicle for expressing thought, it is not the only one, and thought can exist independently of it. Several viewpoints support this idea:
-
Piaget's View (Thought Determines Language): Jean Piaget believed that thought not only determines language but also precedes it. He argued that children form an internal, non-linguistic representation of the world first. For example, when a child observes and later imitates an action, thinking is involved, but not necessarily language. For Piaget, thought is basic and necessary for language to be understood. Language develops to express the concepts and thoughts that a child has already formed.
-
Vygotsky's View (Different Origins): Lev Vygotsky argued that thought and language have separate origins and develop independently in a child until about two years of age. Before this age, thought is preverbal and experienced through actions and senses. Only around age two do thought and language merge to produce verbal thought. This implies the existence of a period where thinking occurs without language.
-
Thinking in Images: As discussed in the chapter, thinking often relies on mental images, which are mental representations of sensory experiences. When we try to remember the route to a place or imagine a scene, we are thinking using visual images, not words. This form of thinking is non-verbal.
Therefore, while language and thought are intricately related and often overlap, thinking is not entirely dependent on language and can occur through non-verbal means like images, actions, and preverbal concepts.
Q9Review Questions
How is language acquired in human beings?
Solution
The acquisition of language in human beings is a complex process that is explained by different psychological perspectives, primarily revolving around the 'nature versus nurture' debate. Most psychologists agree that both innate abilities and environmental factors are important.
-
The Nurture Perspective (Learning): The behaviourist B.F. Skinner believed that language is learned through basic learning principles. This includes:
- Association: Children associate the sight of things with the sounds of words (e.g., seeing a bottle and hearing the word 'bottle').
- Imitation: Children imitate the words and syntax they hear from adults and others around them.
- Reinforcement: Children are rewarded with smiles, hugs, or positive attention when they say something correctly. This reinforcement encourages them to repeat and refine their language use. Shaping and successive approximation guide the child towards speaking like an adult.
-
The Nature Perspective (Innate Proposition): The linguist Noam Chomsky argued that learning principles alone cannot explain the speed and creativity of language acquisition. His main points are:
- Inborn Universal Grammar: Chomsky proposed that children are born with a 'universal grammar', an innate readiness to learn the grammatical rules of any language they are exposed to. Language development is seen as a natural process of maturation, much like physical growth.
- Creative Expression: Children create sentences they have never heard before, which cannot be explained by simple imitation.
- Critical Period: There seems to be a critical period in childhood when language is learned most effectively. Children worldwide also go through the same predictable stages of language development (crying, cooing, babbling, one-word stage, two-word stage).
In conclusion, language acquisition is best understood as an interaction between a child's innate biological predisposition to learn language (nature) and their rich linguistic environment that provides exposure and reinforcement (nurture).
