mcq intro to sensation perception and cognition

Speed readers

Have worse comprehension than careful readers

Metabolic processes explaining multiple ageing declines supports

Common cause hypothesis

Axons and support cells are most abundant in

White matter

PET measures

Metabolic characteristics of tissue

Subtractive paint mixing

Absorbs more wavelengths than any component

We hear sound when

Pressure changes in the air are sensed by the inner ear

Eye movements useful for Parkinson's/ADHD because

Motor and attention deficits affect eye movements

Higher signal-to-noise ratio in older adults means

More difficulty understanding speech in background noise

A modular system is

Autonomous

Electrical potentials measured by

Single-unit recording and EEG

Cognitive psychology view of modules

Modules can be hypothetical

Light enters the eye through

The cornea and the pupil

Retina region between fovea and periphery

Parafovea

Advertising exploits word recognition by

Automatic word recognition without attention

Limbic system includes

Amygdala, cingulate gyrus, hippocampus

Problem with high-contrast acuity chart

It can't measure all aspects of contrast sensitivity

Pinching your nose affects

Orthonasal, retronasal olfaction and flavour

Blind spot is

Peripheral retina with no photoreceptors

Thalamus role

Transporting auditory information to cortex

Cortical area responding only to auditory input from birth

Innately specified module

Stroop Effect

Slowing due to competing information

Salty taste receptors

Fungiform, foliate, circumvallate papillae

Inhibition of return linked to

Exogenous cues

Light is

Electromagnetic radiation

TRACE model speech segmentation

Phonemes activate multiple word candidates which compete

McGurk Effect shows

Rapid integration of visual and auditory speech

Single-unit recording

Measures activity from one neuron

Preventing object slippage relies on

Slowly adapting mechanoreceptors

Integrated Competition Model

Selection biased by interactions across levels

V5 lesions impair

Motion perception

Basic neuron units

Axon, dendrites, cell body

Case "AI" head movements

Sampling highest-acuity retinal regions

Violet paper reflects

Short and long wavelengths

Hyperpolarisation phase

Membrane becomes more negative then returns to rest

Cones are

Responsible for colour vision

Glaucoma affects

Peripheral vision

Stable vs unstable perception with eye movements

Congenital vs acquired nystagmus

Cerebral blood flow measured by

fMRI and PET

Cortical magnification

More neurons devoted to fovea

Diencephalon regulates

Sensory relay and homeostasis

Visual processing without awareness linked to

Sub-cortical areas

Resting membrane potential

−70 mV, inside more negative

DF (ventral damage) can

Pick up objects accurately
