Which of the following facial features is most crucial for basic face recognition?
Clothing style
Eye shape
Height
Hair color
Eye shape is a stable and distinctive facial feature that the visual system uses to distinguish one person from another. Other traits like hair color or clothing style can change frequently and are less reliable for recognition.
Which contextual clue can help identify a person in a photograph?
Shoe brand
Background setting
Pixel resolution
File format
The background setting provides situational information that can narrow down who is likely present in the image. Technical details or irrelevant personal items are not useful for identity recognition.
Which memory technique involves linking new information to existing knowledge?
Chunking
Rehearsal
Method of loci
Elaborative encoding
Elaborative encoding works by associating new information with concepts you already understand, strengthening memory retention. Other techniques like chunking or loci serve different purposes in memory strategies.
Which principle asserts that we recognize faces by perceiving the whole configuration rather than individual features?
Bottom-up processing
Feature analysis
Holistic processing
Top-down processing
Holistic processing refers to seeing the face as an integrated pattern of features, which is a key principle in face recognition research. Feature analysis focuses on individual parts rather than the overall face structure.
Which subtle cue can differentiate between two similar-looking individuals?
Ear shape
Shoe size
Handwriting style
Favorite food
Ear shape is a minute but distinctive physical characteristic that varies significantly between individuals and aids in accurate identification. Other options like shoe size or favorite food are unrelated to facial recognition.
Which memory technique uses spatial paths to help recall faces and names?
Chunking
Method of loci
Interleaving
Rehearsal
The method of loci involves placing items to be remembered along a familiar mental route, making recall more vivid and organized. Other techniques like interleaving or chunking address different cognitive tasks.
In prototype matching theory, what does a stored prototype represent?
A single facial feature
A context cue
An idealized template of a face
An emotional expression
A stored prototype is a mental average or ideal template against which new faces are compared during recognition processes. It is not limited to a single feature or transient expression.
Which contextual factor is most likely to cause a false recognition in a lineup?
Font style
Room temperature
Weather conditions
Similar clothing
Similar clothing can bias witnesses to mistakenly identify someone who looks alike in attire. Environmental or typographical factors are unrelated to witness memory and recognition errors.
Which micro-expression indicates a genuine smile and helps confirm identity trustworthiness?
Puffy eyelids
Downturned lips
Raised eyebrows
Crow's feet around the eyes
Crow's feet or wrinkles around the eyes appear only during a genuine Duchenne smile, which is difficult to fake and signals authenticity. Other facial movements are less diagnostic of genuine emotion.
In low-light conditions, which auditory cue improves person recognition?
Voice pitch
Background music
Joint creak
Shirt rustle
Voice pitch is a stable auditory characteristic that helps identify individuals when visual information is limited. Ambient sounds like music or clothing noise do not reliably distinguish one person from another.
When distinguishing identical twins, which biometric feature is most reliable?
Iris pattern
Height
Handwriting
Shoe size
Iris patterns are highly unique and remain constant over time, making them effective for differentiating even genetically identical individuals. Physical traits like height or shoe size are too similar among twins.
Which phenomenon describes faster recognition of familiar faces due to repeated exposure?
Halo effect
Mere exposure effect
Stroop effect
Inattentional blindness
The mere exposure effect refers to improved attitudes and faster recognition of stimuli simply because they are seen more often. The halo effect and other options are unrelated to exposure frequency.
What is the main benefit of chunking features in face memory?
Improves depth perception
Reduces cognitive load by grouping features
Speeds pixel processing
Increases color perception
Chunking organizes multiple bits of information into meaningful groups, reducing memory load and improving recall of facial features. It does not directly affect sensory perception or technical processing.
Which tool aids systematic evaluation of identity-related cues?
Recognition checklist
Geo-locator
Magnifying glass
Histogram equalizer
A recognition checklist standardizes the assessment of visual and contextual cues, ensuring thorough and unbiased evaluation. The other items are technical or general tools not specific to identity analysis.
What does contrast enhancement achieve in poor lighting for identity recognition?
Alters spatial orientation
Highlights feature boundaries
Reduces background noise
Changes skin tone
Contrast enhancement increases the visibility of edges and boundaries of facial features, making recognition easier under suboptimal light. It does not modify actual colors or spatial relations.
Which processing type focuses on spatial relationships between facial features?
Feature processing
Semantic processing
Episodic processing
Configural processing
Configural processing involves perceiving the spatial arrangement and distances between facial features, which is crucial for face recognition. Feature processing refers to analyzing individual parts rather than their configuration.
What term describes the tendency to recognize faces of one's own race more accurately?
False alarm bias
Recency bias
Own-race bias
Confirmation bias
Own-race bias refers to the phenomenon where people are generally better at identifying faces of their own racial group than those of other groups. Other biases listed relate to decision making or memory in different contexts.
In Bayesian models of identity recognition, what component represents the probability of observing sensory data given a particular identity?
Posterior probability
Utility function
Prior probability
Likelihood function
The likelihood function quantifies how probable the observed data are under each possible identity hypothesis. The prior and posterior probabilities concern beliefs before and after seeing the data.
Which effect shows that inverting a face disproportionately impairs recognition performance?
Thatcher illusion
Face inversion effect
Stroop effect
Contrast effect
The face inversion effect demonstrates that turning a face upside down severely disrupts holistic processing and makes recognition much harder. The Thatcher illusion is related but focuses on feature distortions rather than overall inversion.
In signal detection theory applied to identity recognition, what does d-prime measure?
Sensitivity
False alarm rate
Reaction time
Response bias
D-prime is a measure of an observer's ability to distinguish between signal (correct identity) and noise (incorrect identity). It is independent of response bias, which quantifies decision criteria.

Cheat Sheet

  1. Master the Method of Loci - Transform your memory into a mental museum by placing each fact in its own room or on a familiar landmark. This spatial trick turns abstract data into vivid, location-based cues that are impossible to forget. Next time you need to recall a list of concepts, just take a mental stroll through your custom memory palace! Learn more
  2. Understand the Three Laws of Biometrics - Grasp the golden rules - Policy, Process, and Technology - that ensure biometric ID systems respect privacy, follow fair procedures, and use reliable tech. These guiding principles keep your data safe and your recognition tools trustworthy. By combining rights-based policy with smart processes, you'll be a biometric whiz in no time! Learn more
  3. Enhance Recognition Memory - Boost your brain's "aha!" power by connecting new faces or facts to things you already know. When you link a person's name to a funny image or tie a concept to a personal story, your recall goes from "meh" to "magnificent." Try creating a quirky mental scene each time you meet someone new!
