Lecture 19 - Object Perception and Folk Physics

The focus of the current course in cognitive science is:

• Neuroscience

• Artificial Intelligence

• Behavioral Psychology

• Philosophy of Mind

According to Piaget, at what age do infants fail to reach for hidden objects?

• Infants fail to reach for hidden objects at around 8 months of age.

• Infants fail to reach for hidden objects at around 4 months of age.

• Infants fail to reach for hidden objects at around 12 months of age.

• Infants fail to reach for hidden objects at around 18 months of age.

What error do infants make even at 8-12 months according to Piaget?

• A-not-B error

• Conservation error

• Egocentrism

• Object permanence error

What method does Spelke suggest using instead of action-based tasks?

• Cognitive-based tasks

• Perception-based tasks

• Memory-based tasks

• Language-based tasks

True or False: Babies habituated to a cube from one angle do not dishabituate when seeing the cube from another angle.

• True

• False

What is the Principle of Cohesion in folk physics?

• It is the idea that objects that are in contact with each other tend to stay together unless acted upon by an external force.

• It is the concept that objects will always move in a straight line unless acted upon by an external force.

• It is the belief that objects have an inherent tendency to fall towards the earth.

• It is the notion that objects will always seek the path of least resistance.

According to the Principle of Contact, when do surfaces move together?

• When surfaces are in contact with each other.

• When surfaces are far apart.

• When surfaces are parallel to each other.

• When surfaces are perpendicular to each other.

What does the Principle of Solidity state about objects?

• Objects cannot pass through each other.

• Objects can pass through each other.

• Objects have no mass.

• Objects are invisible.

According to the Principle of Continuity, how do objects move?

• According to the Principle of Continuity, objects move in a continuous manner, meaning that their motion is smooth and unbroken, without sudden changes in direction or speed.

• Objects move in a discontinuous manner, with frequent stops and starts.

• Objects move randomly without any predictable pattern.

• Objects move only in straight lines without any curves.

In Spelke & van der Walle (1993), what surprised 3-month-old infants?

• A change in the color of an object

• A change in the shape of an object

• A change in the size of an object

• A change in the position of an object
