Infant Behavior & Development
|December 2, 2006
Summary
Infants imitate interesting physical events by reproducing the action, not the cause. This suggests preverbal infants may believe they must apply force to create phenomena, impacting our understanding of infant cognition.
Area of Science:
- Developmental Psychology
- Cognitive Science
- Infant Behavior
Background:
- Discrepancies exist between infant expectations (looking time) and actions regarding physical causality.
- Previous research has faced criticism regarding claims about infant knowledge.
- Baillargeon (1999) suggests further task examination before revising developmental views.
Purpose of the Study:
- To investigate a new discrepancy indicating what is salient for preverbal infants.
- To explore infant imitation of physical events, specifically a bouncing ball.
- To analyze whether infants imitate the cause or the effect of an observed action.
Main Methods:
- Examined Uzgiris-Hunt test performances of 40 infants (7.6-26.9 months old).
- Observed infant reactions to a bouncing ball event.
- Compared imitation performances between infants who reproduced the drop versus those who reproduced the bounce.
Main Results:
- Infants were captivated by the bouncing ball.
- Most infants reproduced the bounce action (hitting the ball) rather than the experimenter's drop action.
- Two interpretations suggest goal-directed imitation of interesting phenomena.
Conclusions:
- Infants may imitate phenomena they find interesting by reproducing the action.
- A possible interpretation is that infants believe they must apply force to make events happen.
- Findings contribute to understanding preverbal infants' understanding of physical causality and imitation.

01:20Immunogold Electron Microscopy
Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.
01:29Kohlraush’s Law and its Applications
Kohlrausch's law explains that at infinite dilution, where dissociation is complete, each ion's contribution to the conductivity of the electrolyte is independent of the nature of other ions present in the solution. It also implies that when an electrolyte is highly diluted, the conductance of the electrolyte is the sum of the individual conductances of the ions it generates upon dissociation. The quantity of electricity an ion carries is proportional to its molar ionic conductance, which...
01:14Acid Halides to Ketones: Gilman Reagent
Lithium dialkyl cuprate, also known as Gilman reagents, selectively reduces acid halides to ketones. The acid chloride is treated with Gilman reagent at −78 °C in the presence of ether solution to produce a ketone in good yield.
As shown below, the mechanism proceeds in two steps. First, one of the alkyl groups of the reagent acts as a nucleophile and attacks the acyl carbon of the acid chloride to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen double...

01:19Masking and Demasking Agents
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...

03:45Formation of Complex Ions
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
02:20The Small x Assumption
If a reaction has a small equilibrium constant, the equilibrium position favors the reactants. In such reactions, a negligible change in concentration may occur if the initial concentrations of reactants are high and the Kc value is small. In such circumstances, the equilibrium concentration is approximately equal to its initial concentration. This estimation can be used to simplify the equilibrium calculations by assuming that some equilibrium concentrations are equal to the initial...
