2439545983AttentionThe process of focusing on some objects while ignoring others. Can enhance the processing of the attended object.0
2439546543Attentional CaptureOccurs when stimulus salience causes an involuntary shift of attention.1
2439547657AutismA serious developmental disorder in which one of the major symptoms is the withdrawal of contact from other people.2
2439547979Balint's SyndromeA condition resulting from damage to a person's parietal lobe. One characteristic of this syndrome is an inability to focus attention on individual objects.3
2439548319BindingThe process by which features such as color, form, motion, and location are combined to create our perception of a coherent object.4
2439549383Binding ProblemThe problem of how neural activity in many separated areas in the brain is combined to create a perception of a coherent object.5
2439550228Change BlindnessDifficulty in detecting differences between two visual stimuli that are presented one after another, often with a short blank stimulus interposed between them. Also occurs when part of a stimulus is changed very slowly.6
2439550560Conjunctional SearchA visual search task in which it is necessary to search for a combination (or conjunction) of two or more features on the same stimulus to find the target.7
2439551584DishabituationAn increase in looking time that occurs when a stimulus is changed.8
2439552190Dual-Task ProcedureAn experimental procedure in which subjects are required to carry out simultaneously a central task that demands attention and a peripheral task that involves making a decision about the contents of a scene.9
2439553260Feature Integration TheoryA theory proposed by Treisman to explain how an object is broken down into features and how these features are recombined to result in a perception of the object.10
2439554376Feature SearchA visual search task in which a person can find a target by searching for only one feature.11
2439554645FixationThe brief pause of the eye that occurs between eye movements as a person scans a scene.12
2439555102Focused Attention StageThe stage of processing in feature integration theory in which the features are combined13
2439555653HabtituationPaying less attention to the same stimulus that is presented repeatedly. For example, infants look at a stimulus less and less on each successive trial.14
2439556137High-Load TaskTask that involves more processing resources and that therefore uses more of a person's perceptual capacity.15
2439556897Illusory ConjunctionIllusory combination of features that are perceived when stimuli containing a number of features are presented briefly and under conditions in which focused attention is difficult. For example, presenting a red square and a blue triangle could potentially create the perception of a red triangle.16
2439557353Inattentional BlindnessA situation in which a stimulus that is not attended is not perceived, even though the person is looking directly at it.17
2439558600Load Theory of AttentionLavie's proposal that the amount of perceptual capacity that remains as a person is carrying out a task determines how well the person can avoid being distracted by task-irrelevant stimuli. If a person's perceptual load is close to perceptual capacity, the person is less likely to be distracted by task-irrelevant stimuli.18
2439558898Low-Load TaskA task that uses only a small amount of the person's perceptual capacity.19
2439559532Perceptual CapacityThe resources a person has for carrying out perceptual tasks.20
2439560098Perceptual CompletionThe perception of an object as extending behind occluding objects.21
2439560419Perceptual LoadThe amount of a person's perceptual capacity needed to carry out a particular perceptual task.22
2439562995Preattentive StageAn automatic and rapid stage of processing, proposed by Treisman's feature integration theory, during which a stimulus is decomposed into individual features.23
2439563407PrecueingA procedure in which a cue stimulus is presented to direct an observer's attention to a specific location where a test stimulus is likely to be presented. This procedure was used by Posner to show that attention enhances the processing of a stimulus presented at the cued location.24
2439564057Saliency MapA "map" of a visual display that takes into account characteristics of the display such as color, contrast, and orientation that are associated with capturing attention.25
2439564748Same-Object AdvantageThe faster responding that occurs when enhancement spreads within an object. Faster reaction times occur when a target is located within the object that is receiving the subject's attention, even if the subject is looking at another place within the object.26
2439565151Scene SchemaAn observer's knowledge about what is contained in typical scenes. An observer's attention is affected by knowledge of what is usually found in the scene.27
2439565531Scene StatisticsThe probability of various things occurring in the environment.28
2439566572Spatial AttentionAttention to a specific location.29
2439567179Stimulus SalienceCharacteristics such as bright colors, high contrast, and highly visible orientations that cause stimuli to stand out and therefore attract attention.30
2439567508Task-Irrelevant StimuliStimuli that do not provide information relevant to the task at hand.31
2439568087Visual ScanningMoving the eyes to focus attention on different locations on objects or in scenes.32
2439570590Covert AttentionAttention without looking. Seeing something out of the corner of your eye, for example33
2439571353Overt AttentionAttention that involves looking directly at the attended object.34
2439572541Saccadic Eye MovementRapid Eye movement between fixations that occurs when scanning a scene.35

999638534SNS (somatic nervous system)pupil dilation = why does this make sense? (dimly let, allows you to see main things, i.e. movement; you don't need details for survival and quick action).14
999638535Path of Messagesreceptors --> bipolar cells --> ganglion cells. acuity is a property of low convergence (straight line, no branching off in the cells)15
999638536Receptor Actionno action potentials. Rhodopsin (pigment) absorbs light. G-protein coupled receptor. Receptive fields: respond to some aspects of stimuli16

549603549What is attention?The ability to select and focus on specific stimuli, whether internal or external.0
549603550Cocktail party effectAbility to pay attention to others; filter out other stimuli; We do not focus on every stimulus in the environment1
549603551Two types of attentionOvert Covert2
549603552CovertAttending to a specific stimulus without sensory organ reorientation3
549603553OvertAttending to a specific stimulus by physically reorienting sensory organs4
549603554Divided attention tasksA task in which a subject is directed to process two or more sets of simultaneous stimuli; See what affects they get out of the different sets of stimuli; Shows attention is limited5
549603555Inattentional Blindness/Change BlindnessThe failure to perceive a stimulus due to attentional demands; Shows attention is limited6
549603556Divided Attention Task: Dichotic PresentationSubject can only report info from attended ear Often times will even miss hearing their own name. Shows that attention is focused to a subset of stimuli7
549603557FilteringNot all sensory information can (or should) be processed consciously8
549603558Attentional bottleneckThe "gate" through which stimuli must past to reach awareness9
549603559Early vs. Late SelectionEarly → non-relevant stimuli are excluded from attention before higher level processing. Late → non-relevant stimuli are excluded from attention after high level processing (i.e. word meanings)10
549603560Early vs. Late depends on:perceptual load11
549603561Perceptual LoadHigh perceptual load - brain will filter out info early ex. doing a very difficult math problem, would not hear your own name if someone said it If basic - low perceptual load - filter later ex. easy math problem, would hear your name if someone said it12
549603562Two types of attention shifts?Endogenous attention and Exogenous attention13
549603563Endogenous attentionVoluntary shift in attention; from internal motivations Top-down process → high level brain processes (i.e. reasoning, decision making, etc.) modulating low level brain processes (i.e. sensation/perception)14
549603564Exogenous attentionReflexive, involuntary shift in attention Bottom-up process (ex. someone shoots a gun near you)15
549603565Neural Correlates of AttentionSubcortical and Cortical16
549603566In Subcortical, Superior Colliculus:Cells fire more, when gaze shift related to attentional shift17
549603567In Subcortical, Pulvinar:more active during tasks that require extensive filtering18
549603568In Cortical, Dorsal Frontoparietal System:voluntary; Intraparietal Sulcus (IPS) and Frontal Eye Field (FEF); IPS and FEF modulate endogenous attention19
549603569In Cortical, Right temporoparietal systemreflexive; Ventral frontal cortex (VFC) and Temporoparietal Junction (TPJ); VFC and TPJ modulate exogenous attention20
549603570Intraparietal Sulcus (IPS)Individual neurons will fire more for overt and covert attention21
549603571Frontal Eye Field (FEF)Damage results in inability to prevent gaze shifts to distracters22
549603572Ventral frontal cortex (VFC)Involved in working memory Thought to detect novelty Assigns values of importance23
549603573Temporoparietal Junction (TPJ)Shows increased activity when attending to unexpected stimuli; VFC then relays to TPJ if it is important enough24
549603574Hemispatial neglect● Cause - Damage to the RIGHT parietal lobe - Damage to left parietal lobe will not result in neglect ● Symptoms - Inability to attend to stimuli on the left side of space - Not limited to visual attention - Attentional paralysis of the left side of the body - Otherwise normal sensory processing and motor control25
549603575ADHD - Attention deficit hyperactivity disorder- Very prevalently diagnosed disorder 5% of all children are diagnosed; 3/4ths male - One stimulus is not enough, they are seeking more stimuli in order to get enough/more stimulus/arousal26
549603576ADHD CausesLargely unknown Decreased arousal levels Decreased reward processing in the nucleus accumbens (dopamine dependent) Reduced brain size in frontal areas and the cerebellum27
549603577ADHD SymptomsTrouble paying attention More impulsive than controls Hyperactive28
549603578ADHS TreatmentStimulants: methylphenidate (Ritalin) - Amphetamine derivatives - Thought to increase normal arousal - Abates stimulus seeking behavior Behavioral therapy Non-stimulants Atomoxetine and guanfacine29
549603579ConsciousnessBook's definition: "the state of being aware that we are conscious." My definition: "The subjective experience in its entirety"30
549603580QualiaSingle subjective experiences31
549603581Dualismthe body and the mind are ontologically different32
551971162Monismthe body and the mind are one in the same33
551971163What are the Two problems of Consciousness?●Easy Problem - "Understanding how particular patterns of neural activity create specific conscious experiences" - What you are thinking ●Hard Problem - "How can we understand the brain processes that produce people's subjective experiences of their conscious perceptions?" - Why that brain pattern makes you think that way; How you are experiencing that scene34
551971164Easy ProblemFMRI scans can already distinguish between simple visual scenes35
551971165Hard ProblemWe cannot explain why certain brain activation create qualia. Or if qualia are the same or different for each individual. Even if have same brain activity, do not know if you are experiencing the same thing36
551971166Comais a state of extreme unresponsiveness, in which an individual exhibits no voluntary movement or behavior.37
551971167Anesthesiainsensibility; Don't know if it is a loss of consciousness or not Sensory signals can still be recorded If sensory information is still processed, what does it mean to be unconscious?38
551971168AmnesiaEither the loss of past memories or the inability to produce new memories39
551971169Amnesia and AlcoholThought to interact with the GABA system When you black out are you conscious or not? You don't have memory but you are still able to perform tasks, Capable of complex intentional actions40
551971170Cognitively impenetrablebasic neural processes that cannot be experienced through introspection Can't think about doing them Executive function → conscious Heart Rate → unconscious Breathing → both41
551971171Executive functionIn prefrontal cortex; The high-level control of other cognitive functions in order to attend to important stimuli and make suitable plans for action. Ex. Decision making, Valuation, Planning, Task switching, Working memory → the ability to temporarily store and manipulate information42
551971172The Prefrontal CortexThe region of neocortex anterior to the motor and premotor areas Orbitofrontal Dorsolateral ● Highly interconnected with itself and the rest of the brain Activated during executive function tasks43
551971173Damage to the Prefrontal cortexDamage will affect many aspects of cognition: Emotion, motor, and cognitive functions Ex. Phineas Gage - Changes in personality and executive function44
551971174Trans-orbital LobotomySymtoms: Apathy (Lack of desire to do anything), Impulsiveness, Blunting of personality, Seizures, Distractibility, Irresponsibility45
551971175Are animals conscious?Group of neuroscientists recently (2012) declared that many animals are in fact conscious to some degree46
551971176Mirror TestTest for self awareness; Implies that these animals have an overt sense of self, which then implies that these animals are conscious to some extent.47
551971177Free Will"the ability to make decisions and actions in a non-deterministic manner"; "Free will" decision can be imaged 5- 10 seconds before the person is aware they made the decision. Conscious, free decisions may be predetermined by unconscious brain processes.48
551971178Consciousness, like wetness, is an emergent property of many specialized units working together....49

407170548Concept 14.1 Mendel used the scientific approach to identify two laws of InheritanceThe Law of Segregation The Law of Independent Assortment0
407170549CharacterAn observable heritable feature that may vary among individuals.1
407170550TraitOne of two or more detectable variants in a genetic character.2
407170551True-BreedingReferring to organisms that produce offspring of the same variety over many generations of self-pollination.3
407170552hybridizationIn genetics, the mating, or crossing, of two true-breeding varieties.4
407170553P GenerationThe true-breeding (homozygous) parent individuals from which F1 hybrid offspring are derived in studies of inheritance; P stands for "parental."5
407170554F1 generationThe first filial, hybrid (heterozygous) offspring arising from a parental (P generation) cross.6
407170555F2 generationThe offspring resulting from interbreeding (or self-pollination) of the hybrid FF1 generation.7
407170556The Law of segregationMendel's first law, stating that the two alleles in a pair segregate (separate from each other) into different gametes during gamete formation.8
407170557AlleleAny of the alternative versions of a gene that may produce distinguishable phenotypic effects.9
407170558Dominant AlleleAn allele that is fully expressed in the phenotype of a heterozygote.10
407170559Recessive AlleleAn allele whose phenotypic effect is not observed in a heterozygote.11
407170560GenotypeThe genetic makeup, or set of alleles, of an organism.12
407170561PhenotypeThe EXPRESSED/observable physical and physiological traits of an organism, which are determined by its genetic makeup.13
407170562The Law of SegregationMendel's first law, stating that the two alleles in a pair segregate (separate from each other) into different gametes during gamete formation.14
407170563Punnett SquareA diagram used in the study of inheritance to show the predicted genotypic results of random fertilization in genetic crosses between individuals of known genotype.15
407170564HomozygousHaving two identical alleles for a given gene.16
407170565HeterozygousHaving two different alleles for a given gene.17
407170566PhenotypeExpressed. The observable physical and physiological traits of an organism, which are determined by its genetic makeup.18
407170567GenotypeThe genetic makeup, or set of alleles, of an organism.19
407170568TestcrossBreeding an organism of unknown genotype with a homozygous recessive individual to determine the unknown genotype. The ratio of phenotypes in the offspring reveals the unknown genotype.20
407170569The Law of Independent AssortmentMendel's second law, stating that each pair of alleles segregates, or assorts, independently of each other pair during gamete formation; applies when genes for two characters are located on different pairs of homologous chromosomes or when they are far enough apart on the same chromosome to behave as though they are on different chromosomes.21
407170570MonohybridsAn organism that is heterozygous with respect to a single gene of interest. All the offspring from a cross between parents homozygous for different alleles are monohybrids. For example, parents of genotypes AA and aa produce a monohybrid of genotype Aa.22
407170571Monohybrid CrossA cross between two organisms that are heterozygous for the character being followed (or the self-pollination of a heterozygous plant).23
407170572DihybridsAn organism that is heterozygous with respect to two genes of interest. All the offspring from a cross between parents doubly homozygous for different alleles are dihybrids. For example, parents of genotypes AABB and aabb produce a dihybrid of genotype AaBb.24
407170573Dihybrid CrossA cross between two organisms that are each heterozygous for both of the characters being followed (or the self-pollination of a plant that is heterozygous for both characters).25
407170574What is Mendel's Second Law?The Law of Independent Assortment. Mendel's second law, stating that each pair of alleles segregates, or assorts, independently of each other pair during gamete formation; applies when genes for two characters are located on different pairs of homologous chromosomes or when they are far enough apart on the same chromosome to behave as though they are on different chromosomes.26
407170575Concept Check 14.1 Draw It. Pea Plants heterozygous for flower position and stem length (AaTt) are allowed to self pollinate, and 400 of the resulting seeds are planted. Draw a Punnett square for this cross. How many offspring would be predicted to have terminal flowers and be dwarf? (See Table 14.1)refer to diagram27
407170576Concept Check 14.1 What if? List all gametes that could be made by a pea plant heterozygous for seed color, seed shape, and pod shape (YyRrIi; see Table 14.1). How large a Punnett square would you need to draw to predict the offspring of a self-pollination of this trihybrid?See table28
407170577Concept Check 14.1 Make Connections. In some pea plant crosses, the plants are self-pollinated. Refer back to Concept 13.1 (pp. 248-249) and explain whether self-pollination is considered asexual or sexual reproduction.Asexual29
407170578Which choice below is a basic difference between Mendel's particulate hypothesis and the hypothesis of blending inheritance? (eText Concept 14.1) The blending inheritance hypothesis, but not the particulate hypothesis, maintained that mutation is the major source of new gene combinations. The blending inheritance hypothesis, but not the particulate hypothesis, maintained that the two alleles at any given locus are always different. The blending inheritance hypothesis, but not the particulate hypothesis, maintained that the traits governed by genes in the egg are different from the traits governed by genes in the sperm. The blending inheritance hypothesis, but not the particulate hypothesis, maintained that after a mating, the genetic material provided by each of the two parents is mixed in the offspring, losing its individual identity. All of the listed responses are correct.The blending inheritance hypothesis, but not the particulate hypothesis, maintained that after a mating, the genetic material provided by each of the two parents is mixed in the offspring, losing its individual identity. The blending hypothesis maintained that the genetic material contributed by the two parents mixes in a manner analogous to the way blue and yellow paints blend to make green.30
407170579If a plant variety is true-breeding for a dominant trait, then _____. (eText Concept 14.1) if the plant were allowed to self-pollinate, the dominant and recessive traits would consistently appear in a 3:1 ratio among the progeny the plant is heterozygous for the trait if the plant were crossed with a heterozygote, one-half of the progeny would show the dominant trait, and one-half would show the recessive trait if the plant were allowed to self-pollinate, all of the progeny would have the dominant trait the variety is unable to mutateif the plant were allowed to self-pollinate, all of the progeny would have the dominant trait31
407170580A = big apples; R = red apples; a = small apples; r = yellow apples. You have one tree that produces big yellow apples and another tree that produces small red apples. When the two are crossed, you find that half of the new trees produce big red apples and half produce big yellow apples. What are the genotypes of the parents?
