MODULE - I Foundations of Psychology Notes 9PSYCHOLOGY SECONDARY COURSE Methods of Psychology 2 METHODS OF PSYCHOLOGY In the last lesson we noted that the interpretation of a psychological phenomenon by a psychologist may differ from that of a novice. A psychologist follows a systematic scientific procedure which has sound theoretical base in order to explain and interpret the phenomenon. Psychology has various methodological ways or approaches to understand and explain psychological phenomena. We will be studying about some of these approaches. In order to obtain responses from individuals a number of psychological tools or instruments are used. The responses taken on those tools constitute the basic data which are analyzed to study human experiences, mental processes and behaviours. In this lesson we will discuss these aspects in detail. OBJECTIVES After studying this lesson, you will be able to: • explain the different approaches to the study of psychological processes; • describe some important methods used in understanding human behaviour; and • describe various instruments used in understanding behaviour and psychological processes. 2.1 APPROACHES TO THE STUDY OF PSYCHOLOGICAL PROCESSES As discussed in the previous lesson psychologists use a variety of approaches to describe, predict and control behaviour and mental processes. The main approaches are briefly described below. Biological Approach: This approach focuses on biological structures and phenomena such as brain, genes, hormones, endocrine system and neurotransmitters in order to understand the dynamics of behaviour. Its main focus is on the role of MODULE - I Foundations of Psychology Psychology Secondary Course Notes PSYCHOLOGY SECONDARY COURSE 10 Methods of Ps ch logy different parts of brain in regulating feelings, memories, emotions and other aspects of behaviour. Similarly the impact of over-secretion or under-secretion of different kinds of hormones in governing behaviour is studied. Behaviour genetics as one of the subdesciplines studies the genetic determinants of behaviour. Moreover, this approach looks for physiological basis of human behaviour. Psychoanalytic Approach: The father of psychoanalytic approach Sigmund Freud focused on unconscious libidinal energy in describing the present state of the individual. He studied mind in terms of hierarchical arrangements of experiences in the form of different layers of consciousness (e.g. conscious, preconscious, and unconscious). Freud explored the nature and quality of unconscious through analysis of dreams, slips of the tongue, neuroses, psychoses, work of art, and rituals. He assumed that majority of human behaviours are triggered by unconscious motivation. Thus to understand the present human behaviour the analysis of unconscious mental contents is considered most important. Humanistic Approach: Contrary to Freud, the father of humanistic approach Carl Rogers put greater emphasis on conscious experiences of the present situation, role of interpersonal experiences across the course of life, and people’s capacity to grow toward psychological maturity. This approach basically assumes that a person is an active and self-actualizing agent and has a choice in deciding his behaviour. As a part of the self-actualizing process a person seeks to maintain a congruence between self and experience. However, because of past experiences with conditional positive regard, he may deny or distort the experiences that threaten one’s self-system. Such a self-system can be changed in the therapeutic setting through genuineness, unconditional positive regard, and empathic understating of the client’s problem by the therapist. Behaviorist Approach: The unit of analysis for this approach is explicit, objective and overt behaviour and its relationship with environmental stimulation. The father of behaviorism J. B. Watson emphasized on objective analysis of behaviour. He advocated that behaviour is largely governed by the association between stimulus and response and the behaviour can be shaped in a desired direction by manipulating this association. Cognitive Approach:The cognitive approach emerged as an alternative to the mechanistic paradigm of behaviourism. This approach mainly focuses on the study of information processing capacity of the individual in terms of perception, remembering, thinking, language, reasoning, problem solving and decision making which are called higher mental processes. It proposes that we look out for information in the world and our behaviour depends upon the way we process this information. This approach largely relies on computational models and assumes that behaviour and mental processes can best be understood by treating them in terms of information processing.

Count with the help of tallies how many times these cues are used by the people in the video recording. You can prepare a table with various aspects of observable behaviours; this will help you to understand which non- verbal cue is used more in the Indian setting. Also try to find out about gender difference, do men shake hands more than women, do women touch the feet of elders more than men? You can generate many more questions of your choice. Experimentation: In the case of experiment the experimenter studies the effect of one variable on the other by deliberately manipulating and controlling one variable. The variable which is controlled and manipulated by the experimenter is called independent variable (IV) and the variable on which the impact of independent variable is studied is known as dependent variable (DV). In a simple experiment two groups are formed. One is experimental group in which participants receive the independent variable. The other is control group in which behaviour is observed without giving the independent variable. By manipulating independent variable the experimenter is in a position to state that change induced in one variable brings change in another variable. Apart from these variables the experimenter has to also simultaneously take care of other variables which are beyond his or her control. Such variables are called relevant variables and need to be controlled as they might confound the effect of independent variable. In experimental studies three kinds of relevant variables are taken into account. These are organismic variables, situational variables and sequential variables. Organismic variables are related to personal characteristics of the participants such as age, sex, and personality features. Situational variables are concerned with the quality of physical environment during the conduct of experiment such as temperature, humidity and noise. Sequential variables are related to the very procedure of conducting the experiment when the participant is required to be tested across several conditions. Hence exposure of the participant to varied conditions may result either in attaining proficiency due to practice effects or in developing fatigue and monotony towards experiment. Experimenters use following techniques to control the unwanted effect of relevant variables. (i) Elimination: In this technique extraneous variables are eliminated from the experimental setting. (ii) Making Conditions Constant: In this technique the extraneous variables which cannot be eliminated are kept constant in order to make their effect same during the entire experiment. (iii)Matching: Through this technique the relevant variables are equated or held constant across all the conditions of experiment. (iv)Counter Balancing: This technique is used to minimize the effect of order or sequence. This is usually done by dividing the participants in two groups. On MODULE - I Foundations of Psychology Psychology Secondary Course Notes PSYCHOLOGY SECONDARY COURSE 14 Methods of Ps ch logy first occasion half of the group (Group A) is given task 1 and the other half (Group B) is given task 2. On the second occasion Group A is given task 2 and Group B is given task 1. (v) Random assignment: In the case of random assignment all the participants have equal chance to be exposed to experimental and control conditions. It removes the systematic differences between groups. In addition to experiments carried out in controlled setting (laboratory experiment) experiments are also conducted in natural life conditions. They are called field experiments and quasi experiments. Like laboratory experiment independent variable is manipulated and participants are assigned to different groups. In quasi experiments independent variable is manipulated in natural setting using naturally occurring groups to form experimental and control groups. Case Study: You must have seen a doctor asking personal details in addition to the information about the medical problem of the patient or a media person asking so many questions about various aspects of life while taking interview of a popular person. The purpose behind asking these questions is to know more about the person in terms of his experiences, relationships and interaction with others so as to prepare profile of the person. In psychology this method is called case study. In the field of psychological enquiry case study method has its own importance and relevance. In this method the main unit of analysis is the individual and his experiences across different contexts in life. It focuses on the individual’s interactional patterns with significant others as well as his personal experiences across different real life situations. In order to prepare a case history of data are taken from many sources for example his or her family history, educational life, medical history and social life. This method is very popular in clinical psychology and life span developmental psychology. In order to prepare the case history usually interview, observation and psychological tests are used to obtain information about the individual. The data collected through these techniques are analyzed in detail. A comprehensive profile of the individual is developed which reflects the description of events in his or her life. Case study helps to locate unique experiences of life as well as the various emotional and adjustment problems of the individual. Though case study gives a detailed and in-depth description of individual’s life we cannot make a very conclusive judgment about the individual without further establishing the reliability and validity of such information from various sources such as family members, friends and administration of some standardized psychological measures. Caution should be taken in planning data-collection from the individual and interpretation of the responses given by the individual. Survey: You might be aware that television news channels or newspapers ask you to send your view through SMS on current issues of national or international importance. While doing this they try to seek the opinion of people on those issues MODULE - I Foundations of Psychology Notes 15PSYCHOLOGY SECONDARY COURSE Methods of Psychology to communicate their view to the Government as well as to the society. For example they conduct opinion poll during the election as to which political party enjoys support of the majority of the people. Conducting such a study is called survey research. It is one of the popular research methods not only in psychology but also in other disciplines such as sociology, political science, economics and management. In psychology survey method is generally used to study the pattern of opinions, attitudes, beliefs and values of the people. This method is also used to test the hypothesis about the relationship of variables especially when some incident takes place. For example media tried to analyze the responses of the people across the country after the attack by terrorists on Mumbai. In order to collect the data from people a variety of sources are used such as directly contacting the participants with a set of questions and taking their interview, sending the questionnaire through email or through post and asking them to send SMS by their mobile phones. Thus in survey, research is generally conducted through questionnaire or interview. It can be conducted on a single individual as well as on a group. INTEXT QUESTIONS 2.2 1.

These tools are in the form of paper, instruments or computer software. The administration of these tools helps the psychologist to obtain verbal, written, behavioural or physiological responses. In this section we will discuss some of the psychological tools which are frequently used in conducting research.

WHAT YOU HAVE LEARNT • There are different approaches to explain, describe, predict and control behaviour and mental processes. The main approaches are Biological, Psychoanalytic, Behaviouristic, Humanistic and Cognitive. Scientific method has the characteristics of being objective, testable, self-correcting and replicable. • Different methods are used to understand human behaviour. Observational method helps to describe a phenomenon in a laboratory or natural setting. It can be participant or non-participant. • Experimental method studies the effect of one variable on another variable by manipulating one and controlling other variables. • Case study focuses on one person. The person is studied in great detail to understand the underlying issues. • A questionnaire consists of a set of questions, which the respondent answers. It can be an open or closed ended. • Interview is a face-to-face interaction regarding a given topic. Interview can be structured or unstructured. TERMINAL QUESTIONS 1.
