- Object permanence: infants understand that objects continue to exist when hidden, even from a young age (around 3.5 months)
- Baillargeon's drawbridge experiment: infants show surprise when an object seems to just disappear, demonstrating an understanding of object permanence
- Infants place more weight on spatiotemporal continuity than on featural continuity
Modeling object permanence: recurrent neural networks (RNNs) can be used to model object permanence
- RNNs can learn to predict the reappearance of occluded objects over longer periods of time
Development of self-recognition
- Rouge test: children around 18-24 months old will respond to a red mark on their nose in a mirror
- Only other animals capable of passing the rouge test are other apes, dolphins, orcas, elephants, magpies, and cleaner wrasse
Mindreading
- Ability to understand other people's mental states
- Allows us to make sense of other people and coordinate behavior with theirs
- Roots of mindreading in early childhood lie in pretend play
- Pretend play involves metarepresentation - use of a representation to represent another representation
False Belief Task
- Tests whether children can abstract away from their own knowledge to understand that someone else can have different (and mistaken) beliefs about the world
- Children do not typically pass the false belief test until around age 4
Shared attention mechanism (SAM)
- Occurs when infants look at objects because they see that another person is looking at that object
- Requires infant to embed representations - to represent that an agent is representing someone else's representation
- Makes possible a range of coordinated social behaviors and collaborative activities

Emotions and Artificial Intelligence

Expression of emotions
- 90% or more of emotional communication occurs through nonverbal channels (facial expression, gesture, voice)
- Ekman identified 7 basic emotions: surprise, fear, disgust, anger, happiness, sadness, and contempt
- Each emotion is expressed by a unique set of muscle contractions in the face
Reading emotions
- Our brains are amazing emotion detectors
- We can accurately predict how others evaluate us based on a quick glance at someone's photo
- Women tend to outperform men on the Reading the Mind in the Eyes Test (RMET)
Identifying microexpressions
- Ekman identified 46 distinct muscular movements (action units) in the face
- Facial Action Coding System (FACS)
Emotions and artificial intelligence: affective computing
- Goals: create computers and robots with the ability to recognize emotions in people
- Create machines that can express emotions
- Examples: Kismet project, FaceSense program, FEELIX GROWING consortium### Imagery and Ambiguous Figures
People have difficulty identifying parts of a whole if they haven't included them in their original verbal description of the whole
Some ambiguous figures are difficult to reinterpret in a mental image
Majority of research supports the analog viewpoint, but some people on some tasks use a propositional code

Marr's Model of Visual Processing

Marr developed a theory of visual processing that was built on a hierarchy of different levels for studying cognition
System takes a complex pattern of unstructured stimuli in the visual field and interprets them into representations that can serve as input to more complex cognitive functions, such as object recognition
Three stages of processing:
1. Image projected onto the retina is analyzed in terms of intensity of areas of light and dark
2. Features in the raw primal sketch that are similar in size and orientation get grouped
3. Image is then transformed into a 3-D sketch, with axes of symmetry and elongation linking object parts

Subliminal Perception and Priming

Subliminal perception: messages presented below one's absolute threshold for conscious awareness may influence behavior
Priming: unconscious activation of particular associations in memory
Research on scrambled-sentence test and guilty knowledge test

Lie Detection

Polygraph lie detectors: measure several physiological responses accompanying emotional arousal
Problems with polygraph: arousal associated with lying is no different from arousal caused by other stressful situations
Alternative methods of lie detection: guilty knowledge test, brain fingerprinting, and fMRI brain imaging

Individual Differences in Response to Sensory Stimulation

Introverts vs. extraverts: introverts salivate more to lemon juice, tend to retain elevated heart rate longer after exposure to noxious odors, and are more sensitive to pain
Synesthesia: stimulation of one modality leads to perceptual experience in another
Two theories of synesthesia: 1) brain architecture of synesthetes is equipped with more connections between neurons, causing the usual modularity to break down; 2) "feed-backward" connections that carry information from high-level multisensory areas of the brain back to single sense areas are not properly inhibited

Learning and Cognitive Styles

Visualizers vs. verbalizers: neural correlates of visual vs. verbal cognitive styles
Aphantasia: inability to visualize, may be congenital or acquired
Teaching math without words: using visual feedback to teach math concepts

Learning without Reinforcement

Cognitive maps: learning can occur even when no reinforcement is received and no response is made
Overjustification effect: rewards can undermine motivation
Role of motivation in learning: studies of expert tutors found that they avoid telling a child they are wrong, even lying to do so### Successful Aging and Brain Regions
In successful agers, the regions of the brain regulating emotions are thicker, specifically the midcingulate cortex and anterior insula.
Engaging in activities that require hard work and cause mental fatigue, such as grappling with a math problem, can increase the chances of remaining sharp into old age.

Memory Processing and Forgetting

Memory is an information processing system involving three stages: encoding, storage, and retrieval.
Forgetting can occur due to problems in any of these stages.
Encoding failure: information never enters long-term memory, often due to lack of attention.
Storage decay: information stored in long-term memory gradually fades, but this process is not as severe as commonly thought.
- Research has shown that people can remember a significant amount of information even after 50 years.

Brain Structures and Memory

Two key structures involved in processing and storing new explicit memories are:
- Frontal lobes: responsible for recalling information and holding it in working memory.
- Hippocampus: acts as a "save" button for explicit memories, temporarily holding information before it is stored elsewhere in the brain.

Memory Disorders and Dissociation

Dissociation: when brain damage affects two behaviors very differently, suggesting they are produced by different processes.
Examples of dissociation:
- Clive Wearing, who suffered damage to his hippocampus and could not form new explicit memories, but retained his musical abilities.
- People with full temporal lobe amnesia, who cannot form new explicit memories but can form new implicit memories.
The hippocampus is central to the formation of explicit memories, and damage to it can lead to difficulties in forming new memories.

Alzheimer's Disease

A disease that occurs in the latter part of life, characterized by deterioration of memory, reasoning, and language abilities.
Associated with the loss of neurons in cortical and sub-cortical regions, leading to a decline in cognitive abilities.
Risk factors for Alzheimer's include:
- Genetic components
- Higher risk of disease in those who have previously suffered a stroke or head trauma
- Conditions associated with cardiovascular disease
- Low levels of vitamin D and certain B vitamins
- Exposure to lead and toxic substances

Sleep Deprivation and Cognitive Function

Sleep deprivation can cause irritability, fatigue, impaired concentration, and creativity, as well as increased vulnerability to accidents.
Surprisingly, people are often unaware of the impact of sleep deprivation on their concentration, judgment, and other cognitive functions.

ACT-R: A Hybrid Cognitive Architecture

A cognitive architecture that incorporates both symbolic and subsymbolic information processing.
Consists of a modular organization with a perceptual-motor layer, a cognitive layer, and a subsymbolic base.
The cognitive layer is organized into "chunks" of declarative memory, which are encoded as production rules.
The subsymbolic base uses artificial neural networks to model the accessibility of information in declarative memory.

Cognitive Development

Development of depth perception: infants who have had experience crawling develop wariness of heights.
Piagetian stages of cognitive development:
- Sensorimotor stage (birth - 2 years): children act on objects, coordinate sensory experiences, and form schemas.
- Pre-operational stage (2-7 years): children develop symbolic thinking and engage in pretend play.
- Concrete operations stage (7-11 years): children develop higher-order schemas and understand reversible consequences of actions.
- Formal operations stage (over 11 years): children develop ability to engage in hypothetical and deductive reasoning.

Language and Thought

Models of language learning:
- Nativist views: language acquisition is facilitated by an innate language acquisition device.
- Connectionist models: language learning is simulated using artificial neural networks.
- Bayesian language learning: language learning is modeled using Bayesian statistical methods.
The relationship between language and thought is complex, and there is evidence for both sides of the debate.

Problem Solving and Heuristics

Mental set: the tendency to approach a problem in a particular way, especially if it has been successful in the past.
Functional fixedness: the tendency to think of things only in terms of their usual functions.
Heuristics: rule-of-thumb strategies that allow one to reduce the number of operations tried in solving a problem.
Strategies for improving problem solving:
- Understand the problem
- Represent the problem effectively using symbols, matrices, diagrams, and visual images
