Unit 2 Section 1: Environmental Perception

Vocabulary practice flashcards covering key definitions, theories, research methods, and phenomena from Chapter 2: Environmental Perception and Cognition.

Environmental Perception

The initial information-gathering and first-impressions phase of collecting information about natural and built environments through all the senses.

Environmental Cognition

The overarching psychological process of how people think about, conceptualize, and mentally represent places.

Spatial Cognition

A branch of environmental cognition concerning how people acquire, store, organize, and recall information about locations, distances, and spatial arrangements in natural and built settings.

Object Perception

A traditional perceptual research approach focusing on isolated, simple stimuli in controlled laboratory environments, emphasizing properties such as brightness, color, form, depth, and apparent movement.

Environmental Numbness

A lack of awareness of one's physical surroundings, often occurring when attention is commanded by books, daydreams, or companions, which can lead to overlooking hazards or gradual degradation like pollution.

Weber-Fechner Law

A psychophysical principle cited by Robert Sommer illustrating that as ambient pollution levels rise, progressively larger increments of new pollution are required before individuals perceive that conditions have deteriorated.

Time-Sampling

An on-line self-report research method where observers move through a setting and report at predetermined intervals exactly what they are looking at or listening to without relying on retrospective memory.

Behavior-Inference Method

An indirect research technique that assesses perception through observable actions, such as recording the length of time museum visitors spend viewing an exhibit to measure interest.

Psychophysical Method

A measurement approach utilizing magnitude estimations in which observers adjust a physical variable, such as light brightness, in direct proportion to their perception of a psychological attribute, such as architectural complexity.

Size Constancy

The learned perceptual tendency to view an object as retaining a constant size regardless of changes in viewing distance and the corresponding size of the retinal image.

Carpentered-World Hypothesis

The hypothesis proposing that differences in perception across societies stem from disparities in physical environments, such as urban environments dominated by rectangular objects and straight lines versus rural environments with rounded lines.

Terrestrial Saucer Effect

A perceptual distortion described by Helen Ross that leads mountain climbers to perceive neighboring peaks of equal altitude as higher than their own, or makes uphill slopes appear downhill under certain conditions.

Vanishing Point

The direction implied by the last visible point of a winding trail, toward which travelers systematically err when estimating their travel direction.

Lens Model

Egon Brunswik's conceptual framework demonstrating that qualities of an environment are not perceived directly, but through objectively measurable distal cues filtered into subjective proximal cues.

Distal Cues

Objectively measurable physical characteristics and features of an environmental setting situated on the objective side of Brunswik's lens model.

Proximal Cues

An observer's subjective impressions and perceptual experiences derived from distal cues within Brunswik's lens model.

Ecological Validity

The degree of probabilistic truth connecting the objective state of the environment to distal cues in Brunswik's lens model, representing the odds that a cue reliably reflects the setting.

Cue Utilization

The subjective probabilistic weight an observer assigns to an environmental cue when forming a perceptual judgment, regardless of whether that cue is objectively accurate.

Achievement

The degree of accuracy achieved when an observer's perceptual evaluation of a setting closely corresponds to the actual environment, occurring when cue utilization matches ecological validity.

Probabilistic Functionalism

Egon Brunswik's theoretical view that organisms function as intuitive scientists who must adapt by extracting meaning from environmental cues that have varying probabilities of accuracy.

Affordances

Directly and immediately detectable functional possibilities offered by layouts of surfaces and substances in the environment without requiring cognitive processing, as formulated by James Gibson.

Collative Properties

Characteristics of environmental displays identified by Daniel Berlyne—specifically novelty, incongruity, complexity, and surprisingness—that prompt an observer to attend, inspect, and compare.

Hedonic Tone

A psychological dimension in Daniel Berlyne's theory referring to the amount of beauty or pleasure experienced by an observer in response to an environmental display.

Fittingness

A collative property proposed by subsequent researchers that describes how well a specific environmental element, such as a house, harmonizes with its surrounding physical setting, such as a wilderness.

Phenomenology

A qualitative approach to environmental perception where a trained observer seeks to understand the unique, holistic essence and meaning of a place without relying on external preconceived constructs.

Topophilia

A strong positive emotional attachment to a specific place, characterized within the phenomenology of place.

Existential Outsideness

A feeling of deep alienation, detachment, or estrangement from a place, studied within the phenomenology of place.
