Q

What does mind in the definition of psychology refer to?

A

An individual’s sensations, perceptions, memories, thoughts, dreams, motives, emotions, and other subjective experiences.

It also refers to all of the unconscious knowledge and operating rules that are built into or stored in the brain and that provide the foundation for organizing behavior and conscious experience. (p. 3)

Q

What was the founding of psychology as a formal, recognized, scientific discipline?

A

When Wilhelm Wundt opened the first university-based psychology laboratory in Leipzig in 1879.

At about that same time, Wundt also authored the first psychology textbook and began monitoring psychology’s first official graduate students. The first people to earn Ph.D. degrees in psychology were Wundt’s students. (p. 4)

Q

What are the three fundamental ideas of psychology, all of which were conceived of and debated before psychology was recognized as a scientific discipline?

A
  1. Behavior and mental experiences have physical causes that can be studied scientifically. (Physical causation of behavior)

2 The way people behave, think, and feel is modified over time by their experiences in their environment. (The role of experience)

3 The body’s machinery, which produces behavior and mental experiences, is a product of evolution by natural selection. (The evolutionary basis of mind and behavior) (p. 5 and 11)

Q

What is dualism?

A

A view (the church maintained) that each human being consists of two distinct but intimately conjoined entities, a material body and an immaterial soul. (p. 5)

Q

How was Descartes’ version of dualism?

A

He was familiar with research on the flow of blood and began to regard the body as an intricate, complex machine that generates its own heat and is capable of moving, even without the influence of the soul.

He believed that even quite complex behaviors can occur through purely mechanical means, without involvement of the soul.

He described only the function of thought to the soul (whereas previous philosophers ascribed many functions to the soul). (p. 5-6)

Q

How did Descartes’ version of dualism help pave the way for a science of psychology?

A

To be useful, thought must be responsive to the sensory input channeled into the body through the eyes, ears and other sense organs, and it must be capable of directing the body’s movements by acting on the muscles. Descartes suggested that the soul, though not physical, acts on the body at a particular physical location.

Thread-like structures, which we now call nerves or neurons, bring sensory information by physical means into the brain, where the soul receives the information and, by nonphysical means, thinks about it.

On the basis of those thoughts, the soul then wills movements to occur and executes its will by triggering physical actions in nerves that, in turn, act on muscles.

With its heavy emphasis on the body, Descartes’s dualism certainly helped open the door for a science of psychology. (p. 6)

(Descartes’ dualism placed more emphasis on the role of the body than had previous versions of dualism. To the degree that behavior and the mind have a physical basis, they are open to study just like the rest of the natural world. P. 11)

Q

What reasons can you think of for why Descartes’ theory, despite its intuitive appeal, was unsuitable for a complete psychology?

A

The whole realm of thought, and all behaviors that are guided by thought, are out of bounds for scientific analysis if they are the products of a willful soul. Therefore the theory sets strict limits on what can and cannot be understood scientifically, which few psychologists would accept today. (p. 6)

Q

How did Hobbes’s materialism help lay the groundwork for a science of psychology?

A

He argued that spirit, or soul, is a meaningless concept and that nothing exists but matter and energy, a philosophy now known as materialism.

In his view, all human behavior, including the seemingly voluntary choices we make, can in theory be understood in terms of physical processes in the body, especially the brain.

Conscious thought, he maintained, is purely a product of the brain’s machinery and therefore subject to natural law.

This philosophy places no theoretical limit on what psychologists might study scientifically.

His ideas helped inspire empiricism. (p. 6-7)

(Hobbes’s materialism held that behavior is completely a product of the body and thus physically caused. To the degree that behavior and the mind have a physical basis, they are open to study just like the rest of the natural world. P. 11)

Q

How did the nineteenth-century understanding of the nervous system inspire a theory of behavior called reflexology?

A

The basic arrangement of the nervous system - consisting of a central nervous system (brain and spinal cord) and peripheral nerves that connect the central nervous system to sense organs and muscles - was well understood by the beginning of the nineteenth century.

Some physiologists began to suggest that all human behavior occurs through reflexes - that even so-called voluntary actions are actually complex reflexes involving higher parts of the brain.

It was claimed that all human actions are initiated by stimuli in the environment. (p. 7)

Q

How did discoveries of localization of function in the brain help establish the idea that the mind can be studied scientifically?

A

The concept of localization of function is that specific parts of the brain serve specific functions in the production of mental experience and behavior.

Experiments with animals showed for example that damage to different parts of the brain produces different kinds of deficits in animal’s abilities to move.

Such evidence about the relationships between mind and brain helped to lay the groundwork for a scientific psychology because it gave substance to the idea of a material basis for mental processes. (p. 7-8)

Q

What is empiricism?

A

The idea that human knowledge and thought derive ultimately from sensory experience (vision, hearing, touch, and so forth).

Locke viewed a child’s mind as a tabula rasa, or blank state, and believed that experience serves as the chalk that writes on and fills the slate.

Locke argued that, outside of extremes, children are born with no dispositions to make some types of learning easier than others. (p. 8-9)

Q

When did John Locke live?

A

1632-1704 (p. 8)

17
Q

How would you explain the origin of complex ideas and thoughts according to British empiricism?

A

The fundamental units of the mind are elementary ideas that derive directly from sensory experiences and become linked together, in lawful ways, to form complex ideas and thoughts. (p. 9)

18
Q

What role did the law of association by contiguity play in the philosophy of / school of thought empiricism?

A

Contiguity refers to closeness in space or time, and the law of association by contiguity can be stated as follows:

If a person experiences two environmental events (stimuli, or sensations) at the same time or one right after the other (contiguously), those two events will become associated (bound together) in the person’s mind such that the thought of one event will, in the future, tend to elicit the thought of the other. (p. 9)

So empiricists used the law of association by contiguity to explain how sensory experiences can combine to form complex thoughts. (p. 11)

19
Q

How would you describe the influence that empiricist philosophy has had on psychology?

A

The law of association by contiguity is still regarded as a fundamental principle of learning and memory.

More broadly, most of psychology - throughout its history - has been devoted to the study of the effects of people’s environmental experiences on their thoughts, feelings, and behavior.

The impact of empiricist philosophy on psychology has been enormous. (p. 10)

20
Q

What is nativism?

A

The opposite of empiricism.

The view that the most basic forms of human knowledge and the basic operating characteristics of the mind, which provide the foundation for human nature, are native to the human mind - that is, are inborn and do not have to be acquired from experience. (p. 10)

(Nativism asserts that some knowledge is innate and that such knowledge provides the foundation for human nature, including the human abilities to learn. P. 11)

21
Q

Why is the ability to learn dependent on inborn knowledge? (nativism)

A

To learn anything, any entity must contain some initial machinery already built into it.

At a minimum, that machinery must include an ability to sense some aspects of the environment, some means of interpreting and recording those sensations, some rules for storing and combing those sensory records, and some rules for recalling them when needed.

The mind, contrary to Locke’s poetic assertion, must come with some initial furnishings in order for it to be furnished further through experience.

According to nativist philosophers, human learning is limited by the information and operating rules that are genetically programmed into the human brain. (p. 10)

22
Q

In Kant’s nativist philosophy, what is the distinction between a priori knowledge and a posteriori knowledge?

A

A priori knowledge is built into the human brain and does not have to be learned.

A posteriori knowledge gains one from experience in the environment.

Without the first a person could not acquire the second. (p. 10)

23
Q

How did Darwin’s theory of natural selection offer a scientific foundation for explaining behavior by describing its functions?

A

Darwin’s fundamental idea was that living things evolve gradually, over generations, by a process of natural selection. Those individuals whose inherited characteristics are well adapted to their local environment are more likely to survive and reproduce than are other, less well-adapted individuals.

At each generation, random changes in the hereditary material produce variations in offspring, and those variations that improve the chance of survival and reproduction are passed from generation to generation in increasing numbers.

The principle links humans to the rest of the biological world and explains the origin of brain mechanisms that promote the individual’s survival and reproduction.

Through natural selection, living things have acquired tendencies to behave in ways that promote their survival and reproduction. A key word here is function. (p. 11)

24
Q

When did Charles Darwin live?

A

1809-1882 (p. 10)

25
Q

How did Darwin’s theory of natural selection provide a basis for understanding the origin of a a priori knowledge?

A

Darwin’s work provided psychology with a scientific way of thinking about all the inborn universal tendencies that constitute human nature.

The inherited mechanisms underlying human emotions, drives, perception, learning and reasoning came about gradually because they promoted the survival and reproduction of our ancestors. (p. 11)

26
Q

What were the main differences between physiologists, empiricist philosophers and Darwin?

A

Physiologists were examining the neural mechanisms of behavior.

Empiricist philosophers were analyzing lawful relationships between behavior and the environment.

Darwin was studying the functions of behavior - the ways in which an organism’s behavior helps it to survive and reproduce. (p. 11)

27
Q

When did Immanuel Kant live?

A

1724-1804 (p. 10)

28
Q

What was the difference between Kant and Darwin?

A

Kant understood that the human mind has some innate furnishings, but he had no scientific explanation of how those furnishings could have been built or why they function as they do.

That understanding finally came in 1859 when the English naturalist Charles Darwin published The Origin of Species. (p. 10)

29
Q

How did Darwin help make the world ripe for psychology?

A

He helped convince the intellectual world that we humans, despite our pretentions, are part of the natural world and can be understood through the methods of science. (p. 11)

30
Q

How can you use the section review at the end of each major section of each chapter to guide your thoughts and review before going on to the next section?

A

The main idea or topic of the section is at the top, the sub-ideas or subtopics are at the next level down, and specific facts and lines of evidence pertaining to each sub-idea or subtopic fill the lower parts.

Read each item in the chart and think about it.

How would you explain it to another person?

How does the idea or topic heading the column pertain to the larger idea or topic above it and how is it supported or elaborated upon by the more specific statements below it. (p. 12)

31
Q

How was in the nineteenth-century the applicability of science to mental processes and behavior demonstrated?

A

By physiological studies of reflexes (for example by Ivan Pavlov) and localization of function. (p. 11)

32
Q

What did British empiricists claim?

A

All thought and knowledge are rooted in sensory experience. (p. 11)
