Exploring the habituation-dishabituation paradigm described, we focus on what infants reveal about object properties.
Option 1: 'means-end behaviors' refers to an action sequence where the infant uses a tool or a method to achieve a goal, such as pulling a string to retrieve a toy. This task does not primarily test the persistence of objects when hidden, so labeling the finding as means-end behavior would be mismatched with the typical interpretation of habituation-dishabituation in very young infants.
Option 2: 'object permanence' is the concept that objects continue to exist even when they are hidden from view. In habituation-dishabituation tasks with carrots moving behind a screen, infants’ renewed interest (dishabituation) when the carrot reappears or changes in a way that suggests it still exists supports the presence of object permanence at a surprisingly early age.
Option 3: 'understood gravity' would imply infants have an explicit notion of physical forces like gravity governing the carrot’s movement. The described experiment focuses on whether the carrot still exists behind the screen, not on reasoning about gravity, so this option overstates the cognitive interpretation of the task.
Option 4: 'deferred imitation' involves copying an action after a delay, typically tested with sequences of actions demonstrated by an adult. The carrot behind a screen task does not assess imitation of actions, so labeling it as deferred imitation would be inaccurate.
Thus, considering what the habituation-dishabituation setup measures, the most consistent interpretation is object permanence, while the other options refer to different cognitive abilities that are not the primary focus of this particular experiment.
