Most researchers agree that apes can a. communicate through symbols. b. reproduce most human speech sounds. c. master language in adulthood. d. surpass a human 3-year-old in language skills.

A

What do we know about other animals' capacity for language?

A number of chimpanzees and bonobos have (1) learned to communicate with humans by signing or by pushing buttons wired to a computer, (2) developed vocabularies of nearly 400 words, (3) communicated by stringing these words together, (4) taught their skills to younger animals, and (5) demonstrated some understanding of syntax. But only humans communicate in complex sentences. Nevertheless, other animals' impressive abilities to think and communicate challenge humans to consider what this means about the moral rights of other species.

The most systematic procedure for solving a problem is a(n) _______.

Algorithm

What is the relationship between thinking and language, and what is the value of thinking in images?

Although Benjamin Lee Whorf's linguistic determinism hypothesis suggested that lan- guage determines thought, it is in fact more accurate to say that language influences thought. Different languages embody different ways of thinking, and immersion in bilingual education can enhance thinking. We often think in images when we use implicit (nondeclarative, procedural) memory—our automatic memory system for motor and cognitive skills and classically conditioned associations. Thinking in images can increase our skills when we mentally practice upcoming events.

What cognitive strategies assist our problem solving, and what obstacles hinder it?

An algorithm is a methodical, logical rule or procedure (such as a step-by-step descrip- tion for evacuating a building during a fire) that guarantees a solution to a problem. A heuristic is a simpler strategy (such as running for an exit if you smell smoke) that is usually speedier than an algorithm but is also more error prone. Insight is not a strategy-based solution, but rather a sudden flash of inspiration that solves a problem. Obstacles to problem solving include confirmation bias, which predisposes us to ver- ify rather than challenge our hypotheses, and fixation, such as mental set, which may prevent us from taking the fresh perspective that would lead to a solution.

What brain areas are involved in language processing and speech?

Aphasia is an impairment of language, usually caused by left-hemisphere damage. Two important language- and speech-processing areas are Broca's area, a region of the frontal lobe that controls language expression, and Wernicke's area, a region in the left temporal lobe that controls language reception. Language processing is spread across other brain areas as well, where different neural networks handle specific linguistic subtasks.

How do smart thinkers use intuition?

As people gain expertise, they grow adept at making quick, shrewd judgments. Smart thinkers welcome their intuitions (which are usually adaptive), but when making com- plex decisions they gather as much information as possible and then take time to let their two-track mind process all available information.

Widely reported terrorist attacks, such as on 9/11 in the united States, led some observers to initially assume in 2014 that the missing Malaysian airlines Flight 370 was probably also the work of terrorists. This assumption illustrates the ________ heuristic.

Availability

Which of the following is nOT a characteristic of a creative person? a. expertise b. extrinsic motivation c. a venturesome personality d. imaginative thinking skills

B

______________ ______________ is the part of the brain that, if damaged, might impair your ability to speak words. Damage to ______________ ______________ might impair your ability to understand language.

Broca's area; Wernicke's area

Children reach the one-word stage of speech development at about a. 4 months. b. 6 months. c. 1 year. d. 2 years.

C

a major obstacle to problem solving is fixation, which is a(n) a. tendency to base our judgments on vivid memories. b. tendency to wait for insight to occur. c. inability to view a problem from a new perspective. d. rule of thumb for judging the likelihood of an event in terms of our mental image of it.

C

What was the premise of researcher Noam Chomsky's work in language development?

Chomsky maintained that all languages share a universal grammar, and humans are biologically predisposed to learn the grammar rules of language.

What is cognition, and what are the functions of concepts?

Cognition refers to all the mental activities associated with thinking, knowing, remembering, and communicating. We use concepts, mental groupings of similar objects, events, ideas, or people, to simplify and order the world around us. We form most concepts around prototypes, or best examples of a category.

a mental grouping of similar things is called a _________.

Concept

What is creativity, and what fosters it?

Creativity, the ability to produce novel and valuable ideas, correlates somewhat with aptitude, but is more than school smarts. Aptitude tests require convergent thinking, but creativity requires divergent thinking. Robert Sternberg has proposed that creativity has five components: expertise; imaginative thinking skills; a venturesome personality; intrinsic motivation; and a creative environment that sparks, supports, and refines creative ideas.

When consumers respond more positively to ground beef described as "75 percent lean" than to the same product labeled "25 percent fat," they have been influenced by ________ .

Framing

What is intuition, and how can the availability heuristic, overconfidence, belief perseverance, and framing influence our decisions and judgments?

Intuition is the effortless, immediate, automatic feelings or thoughts we often use instead of systematic reasoning. Heuristics enable snap judgments. Using the availability heuristic, we judge the likelihood of things based on how readily they come to mind, which often leads us to fear the wrong things. Overconfidence can lead us to overestimate the accuracy of our beliefs. When a belief we have formed and explained has been discredited, belief perseverance may cause us to cling to that belief. A remedy for belief perseverance is to consider how we might have explained an opposite result. Framing is the way a question or statement is worded. Subtle wording differences can dramatically alter our responses.

What are the milestones in language development, and how do we acquire language?

Language development's timing varies, but all children follow the same sequence. Receptive language (the ability to understand what is said to or about you) develops before productive language (the ability to produce words). At about 4 months of age, infants babble, making sounds found in languages from all over the world. By about 10 months, their babbling contains only the sounds found in their household lan- guage. Around 12 months of age, children begin to speak in single words. This one- word stage evolves into two-word (telegraphic) utterances before their second birthday, after which they begin speaking in full sentences. Linguist Noam Chomsky has proposed that all human languages share a universal grammar—the basic building blocks of language—and that humans are born with a predisposition to learn language. We acquire a specific language through learning as our biology and experience interact. Childhood is a critical period for learning to speak and/or sign fluently. This is an important consideration for parents of deaf children, who might master oral communication if given a cochlear implant during this critical period. Deaf culture advocates oppose such implants on the grounds that deafness is a difference, not a disability.

What is mental practice, and how can it help you to prepare for an upcoming event?

Mental practice uses visual imagery to mentally rehearse future behaviors, activating some of the same brain areas used during the actual behaviors. Visualizing the details of the process is more effective than visualizing only your end goal.

Oscar describes his political beliefs as "strongly liberal," but he has decided to explore opposing viewpoints. how might he be affected by confirmation bias and belief perseverance in this effort?

Oscar will need to guard against confirmation bias (searching for support for his own views and ignoring contradictory evidence) as he seeks out opposing viewpoints. Even if Oscar encounters new information that disproves his beliefs, belief perseverance may lead him to cling to these views anyway. It will take more compelling evidence to change his beliefs than it took to create them.

Why is it so difficult to learn a new language in adulthood?

Our brain's critical period for language learning is in childhood, when we can absorb language structure almost effortlessly. as we move past that stage in our brain's development, our ability to learn a new language diminishes dramatically.

What are the structural components of a language?

Phonemes are a language's basic units of sound. Morphemes are the elementary units of meaning. Grammar—the system of rules that enables us to communicate—includes semantics (rules for deriving meaning) and syntax (rules for ordering words into sentences).

The three basic building blocks of language are _______ , _______ , and _______ .

Phonemes; morphemes; grammar

What do we know about thinking in other animals?

Researchers make inferences about other species' consciousness and intelligence based on behavior. Evidence from studies of various species shows that other animals use concepts, numbers, and tools and that they transmit learning from one generation to the next (cultural transmission). And, like humans, other species also show insight, self-awareness, altruism, cooperation, and grief.

When young children speak in short phrases using mostly verbs and nouns, this is referred to as ______.

Telegraphic speech

If your dog barks at a stranger at the front door, does this qualify as language? What if the dog yips in a telltale way to let you know she needs to go out?

These are definitely communications. But if language consists of words and the grammatical rules we use to combine them to communicate meaning, few scientists would label a dog's barking and yipping as language.

How many morphemes are in the word cats? How many phonemes?

Two morphemes—cat and s, and four phonemes—c, a, t, and s

1according to Chomsky, all languages share a(n) _______ .

Universal grammar

What factors contribute to our fear of unlikely events?

We tend to be afraid of what our ancestral history has prepared us to fear (thus, snakes instead of cigarettes); what we cannot control (flying instead of driving); what is imme- diate (the takeoff and landing of flying instead of countless moments of trivial danger while driving); and what is most readily available (vivid images of air disasters instead of countless safe car trips).

Why can news be described as "something that hardly ever happens"? How does knowing this help us assess our fears?

if a tragic event such as a plane crash makes the news, it is noteworthy and unusual, unlike much more common bad events, such as traffic accidents. knowing this, we can worry less about unlikely events and think more about improving the safety of our everyday activities. (For example, we can wear a seat belt when in a vehicle and use the crosswalk when walking.)

What is the difference between receptive and productive language, and when do chil- dren normally hit these milestones in language development?

infants normally start developing receptive language skills (ability to understand what is said to and about them) around 4 months of age. Then, starting with babbling at 4 months and beyond, infants normally start building productive language skills (ability to produce sounds and eventually words).

Benjamin Lee Whorf's controversial hypothesis, called ______________ ______________ , suggested that we cannot think about things unless we have words for those concepts or ideas.

linguistic determinism
