Rosa (2010) showed that visual attention — the brain’s ability to selectively filter unattended or unwanted

information from reaching awareness — diminishes with age, leaving older adults less capable of filtering out

distracting or irrelevant information. This age-related “leaky” attentional filter fundamentally impacts the way

visual information is encoded into memory. Older adults with impaired visual attention have better memory

for “irrelevant” information. In the study, the research team examined brain images using functional magnetic

resonance imaging (fMRI) on a group of young (mean age = 22 years) and older adults (mean age = 77 years)

while they looked at pictures of overlapping faces and places (houses and buildings). Participants were asked to

pay attention only to the faces and to identify the gender of the person. Even though they could see the place in

the image, it was not relevant to the task at hand (Read about the study’s findings at http://www.artsci.utoronto.ca/

main/newsitems/brains-ability).

The authors noted:

In young adults, the brain region for processing faces was active while the brain region

for processing places was not. However, both the face and place regions were active in

older people. This means that even at early stages of perception, older adults were less

capable of filtering out the distracting information. Moreover, on a surprise memory

test 10 minutes after the scan, older adults were more likely to recognize what face was

originally paired with what house.

The findings suggest that under attentionally demanding conditions, such as a person looking for keys on a cluttered

table, age-related problems with “tuning in” to the desired object may be linked to the way in which information is

selected and processed in the sensory areas of the brain. Both the relevant sensory information — the keys — and

the irrelevant information — the clutter — are perceived and encoded more or less equally. In older adults, these

changes in visual attention may broadly influence many of the cognitive deficits typically observed in normal aging,

particularly memory.

Key Takeaways

• Biological psychology – also known as biopsychology or psychobiology – is the application of

the principles of biology to the study of mental processes and behaviour.

• Biological psychology as a scientific discipline emerged from a variety of scientific and

philosophical traditions in the 18th and 19th centuries.

• In The Principles of Psychology (1890), William James argued that the scientific study of

psychology should be grounded in an understanding of biology.

• The fields of behavioural neuroscience, cognitive neuroscience, and neuropsychology are all

subfields of biological psychology.

• Biological psychologists are interested in measuring biological, physiological, or genetic variables

in an attempt to relate them to psychological or behavioural variables.

Exercises and Critical Thinking

1. Try this exercise with your group: Take a short walk together without talking to or looking at

one another. When you return to the classroom, have each group member write down what they

saw, felt, heard, tasted, and smelled. Compare and discuss reflecting on some of the assumptions

and beliefs of the structuralists. Consider what might be the reasons for the differences and

similarities.

2. Where can you see evidence of insights from biological psychology in some of the applications

of psychology that you commonly experience today (e.g., sport, leadership, marketing,

education)?

3. Study the functions of the brain and reflect on whether you tend toward left- or right-brain

tendencies.

2.2 Psychodynamic Psychology

Jennifer Walinga

Learning Objectives

1. Understand some of the psychological forces underlying human behaviour.

2. Identify levels of consciousness.

3. Critically discuss various models and theories of psychodynamic and behavioural psychology.

4. Understand the concept of psychological types and identify applications and examples in daily

life.

Sigmund Freud

The psychodynamic perspective in psychology proposes that there are psychological forces underlying human

behaviour, feelings, and emotions. Psychodynamics originated with Sigmund Freud (Figure 2.5) in the late 19th

century, who suggested that psychological processes are flows of psychological energy (libido) in a complex brain.

In response to the more reductionist approach of biological, structural, and functional psychology movements, the

psychodynamic perspective marks a pendulum swing back toward more holistic, systemic, and abstract concepts

and their influence on the more concrete behaviours and actions. Freud’s theory of psychoanalysis assumes that

much of mental life is unconscious, and that past experiences, especially in early childhood, shape how a person

feels and behaves throughout life.

Consciousness is the awareness of the self in space and time. It can be defined as human awareness of both

internal and external stimuli. Researchers study states of human consciousness and differences in perception in

order to understand how the body works to produce conscious awareness. Consciousness varies in both arousal and

content, and there are two types of conscious experience: phenomenal, or in the moment, and access, which recalls

experiences from memory.

First appearing in the historical records of the ancient Mayan and Incan civilizations, various theories of multiple

levels of consciousness have pervaded spiritual, psychological, medical, and moral speculations in both Eastern

and Western cultures. The ancient Mayans were among the first to propose an organized sense of each level of

consciousness, its purpose, and its temporal connection to humankind. Because consciousness incorporates stimuli

from the environment as well as internal stimuli, the Mayans believed it to be the most basic form of existence,

capable of evolution. The Incas, however, considered consciousness to be a progression, not only of awareness but

of concern for others as well.

Sigmund Freud divided human consciousness into three levels of awareness: the conscious, preconscious, and

unconscious. Each of these levels corresponds to and overlaps with Freud’s ideas of the id, ego, and superego. The

conscious level consists of all those things we are aware of, including things that we know about ourselves and

our surroundings. The preconscious consists of those things we could pay conscious attention to if we so desired,

and where many memories are stored for easy retrieval. Freud saw the preconscious as those thoughts that are

unconscious at the particular moment in question, but that are not repressed and are therefore available for recall

and easily capable of becoming conscious (e.g., the “tip of the tongue” effect). The unconscious consists of those

things that are outside of conscious awareness, including many memories, thoughts, and urges of which we are

not aware. Much of what is stored in the unconscious is thought to be unpleasant or conflicting; for example,

sexual impulses that are deemed “unacceptable.” While these elements are stored out of our awareness, they are

nevertheless thought to influence our behaviour.

Figure 2.6 The Levels of Consciousness.

Figure 2.6 illustrates the respective levels of id, ego, and superego. In this diagram, the bright blue line represents

the divide between consciousness (above) and unconsciousness (below). Below this line, but above the id, is

the preconscious level. The lowest segment is the unconscious. Like the ego, the superego has conscious and

unconscious elements, while the id is completely unconscious. When all three parts of the personality are in dynamic

equilibrium, the individual is thought to be mentally healthy. However if the ego is unable to mediate between the

id and the superego, an imbalance occurs in the form of psychological distress.

45 • INTRODUCTION TO PSYCHOLOGY - 1ST CANADIAN EDITION

While Freud’s theory remains one of the best known, various schools within the field of psychology have developed

their own perspectives. For example:

• Developmental psychologists view consciousness not as a single entity, but as a developmental process

with potential higher stages of cognitive, moral, and spiritual quality.

• Social psychologists view consciousness as a product of cultural influence having little to do with the

individual.

• Neuropsychologists view consciousness as ingrained in neural systems and organic brain structures.

• Cognitive psychologists base their understanding of consciousness on computer science.

Most psychodynamic approaches use talk therapy, or psychoanalysis, to examine maladaptive functions that

developed early in life and are, at least in part, unconscious. Psychoanalysis is a type of analysis that involves

attempting to affect behavioural change through having patients talk about their difficulties. Practising

psychoanalysts today collect their data in much the same way as Freud did, through case studies, but often without

the couch. The analyst listens and observes, gathering information about the patient. Psychoanalytic scientists today

also collect data in formal laboratory experiments, studying groups of people in more restricted, controlled ways

(Cramer, 2000; Westen, 1998).

Carl Jung

Carl Jung (1875-1961) expanded on Freud’s theories, introducing the concepts of the archetype, the collective

unconscious, and individuation—or the psychological process of integrating the opposites, including the conscious

with the unconscious, while still maintaining their relative autonomy (Figure 2.7). Jung focused less on infantile

development and conflict between the id and superego, and more on integration between different parts of the

person.

Figure 2.7 Jung’s Theory.

The following are Jung’s concepts that are still prevalent today:

Active imagination: This refers to activating our imaginal processes in waking life in order to tap into the

unconscious meanings of our symbols.

Archetypes: These primordial images reflect basic patterns or universal themes common to us all and that are

present in the unconscious. These symbolic images exist outside space and time. Examples are the shadow, animus,

anima, the old wise person, and the innocent child. There are also nature archetypes, like fire, ocean, river, mountain.

2.2 PSYCHODYNAMIC PSYCHOLOGY • 46

1. Anima is the archetype symbolizing the unconscious female component of the male psyche.

Tendencies or qualities often thought of as feminine.

2. Animus is the archetype symbolizing the unconscious male component of the female psyche.

Tendencies or qualities often thought of as masculine.

3. Self is the archetype symbolizing the totality of the personality. It represents the striving for unity,

wholeness, and integration.

4. Persona is the mask or image a person presents to the world. It is designed to make a particular

impression on others, while concealing a person’s true nature.

5. Shadow is the side of a personality that a person does not consciously display in public. It may have

positive or negative qualities.

6. Dreams are specific expressions of the unconscious that have a definite, purposeful structure

indicating an underlying idea or intention. The general function of dreams is to restore a person’s total

psychic equilibrium.

7. Complexes are usually unconscious and repressed emotionally toned symbolic material that is

incompatible with consciousness. Complexes can cause constant psychological disturbances and

symptoms of neurosis. With intervention, they can become conscious and greatly reduced in their impact.

Individuation: Jung believed that a human being is inwardly whole, but that most people have lost touch with

important parts of themselves. Through listening to the messages of our dreams and waking imagination, we can

contact and reintegrate our different parts. The goal of life is individuation, which is the process of integrating the

conscious with the unconscious, synergizing the many components of the psyche. Jung asserted: “Trust that which

gives you meaning and accept it as your guide” (Jung, 1951, p. 3). Each human being has a specific nature and

calling uniquely his or her own, and unless these are fulfilled through a union of conscious and unconscious, the

person can become sick. Today, the term “individuation” is used in the media industry to describe new printing

and online technologies that permit “mass customization” of media (newspaper, online, television) so that its

contents match each individual user’s unique interests, shifting from the mass media practice of producing the same

contents for all readers, viewers, listeners, or online users (Chen, Wang, & Tseng, 2009). Marshall McLuhan, the

communications theorist, alluded to this trend in customization when discussing the future of printed books in an

electronically interconnected world (McLuhan & Nevitt, 1972).

Mandala: For Jung, the mandala (which is the Sanskrit word for “circle”) was a symbol of wholeness, completeness,

and perfection, and symbolized the self.

Mystery: For Jung, life was a great mystery, and he believed that humans know and understand very little of it. He

never hesitated to say, “I don’t know,” and he always admitted when he came to the end of his understanding.

Neurosis: Jung had a hunch that what passed for normality often was the very force that shattered the personality of

the patient. He proposed that trying to be “normal” violates a person’s inner nature and is itself a form of pathology.

In the psychiatric hospital, he wondered why psychiatrists were not interested in what their patients had to say.

Story: Jung concluded that every person has a story, and when derangement occurs, it is because the personal story

has been denied or rejected. Healing and integration come when the person discovers or rediscovers his or her own

personal story.

Symbol: A symbol is a name, term, or picture that is familiar in daily life, but for Jung it had other connotations

besides its conventional and obvious meaning. To Jung, a symbol implied something vague and partially unknown
