Meeting 4 - Environmental perception

8 important questions on Meeting 4 - Environmental perception

Which differences are there comparing to traditional research? (3)

- Stimuli are complex
- Perceiver in the scene instead of lab
- perceiver is purposive (goal in scene)

Which theories are been used to study environmental perception? (5)

- the lens model of Brunswik (probabilistic funcionalism)
- Berlynes stimulus properties
- Kaplan & Kaplan preference matrix
- Prototypicality preference
- Adaptation Level and the affective appraisal theory (circumplex model)

How is the Lensmodel being used concerning environmental criminal perception?

It's about the probability to become a victim and the feelings individuals have to fear a crime.

Probability -> lens -> subjective probability

(left) Cue validity -> (middle) lens -> (right) cue utilization
                             (Observer accuracy)

(left) Become a crime victim -> (middle) bv no windows at street level of amount of litter -> (right) fear of crime.

Which stimulus properties are been distinguished by Berlyne? (3)

Berlyne tells that there are three different ways to categorize stimulus properties:
1 - Psychophysical
(bv intensity, volume, brightness colors)
2 - Collative: properties based on comparisons between elements
(bv order, complexity, diversity/organised, surprisingness/new)
3- ecological
(what we have learned during evolution and development -> is preference inborn or learned?)

Where is the Kaplan & Kaplan matrix about? CDLM

Every person has two motives for environmental preferences:

1 - understanding
coherence (orderly) and
legibility (well structured space)

2- exploring
mystery (promise of further information and
diversity (different elements in the scene).

After that: judgement.

What does the theory about Prototypicality preferences means?

Preference about environment is dependent on distance to the prototypical example of a category.The closer to the prototype, the more preferred (example church).

What does the Circumplex model of affect means? (Russel & Lanius)

It's a model which includes two dimensions of affective appraisals of places:
- the place is experienced as unpleasant (left) or pleasant
- the place is arousing (high) or not arousing
In the middle it is neutral.

Circumplex model of affect is composed by two theories: adaptation level theory and theory on affect.

What is the Adaptation level theory about?

Judgements about stimuli are always relative to the context, adjust to earlier experiences (what is normal for the individual).

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
