Psychology QUESTION #1460

Question 2081

Which type of memory has the longest duration and largest capacity, often storing information for a lifetime?

Sensory memory
Short-term memory
Long-term memory✔️
Working memory

Correct Answer Logic:

Long-term memory (LTM) has virtually unlimited capacity and can store information for a lifetime. It includes declarative memory (explicit: episodic and semantic) and non-declarative memory (implicit: procedural, priming). Sensory memory lasts milliseconds; short-term memory holds about 7±2 items for 15–30 seconds; working memory is the active, limited-capacity system for immediate cognitive tasks.

Statistics QUESTION #1982

Question 2085

The partial correlation coefficient $r_{12.3}$ between $X_1$ and $X_2$ after eliminating the linear effect of $X_3$ is computed as the simple correlation between:

$X_1$ and $X_2$ directly
The residuals $X_{1.3}$ and $X_{2.3}$ from their respective regressions on $X_3$✔️
The standardized values of $X_1$ and $X_2$
The ranked values of $X_1$ and $X_2$

Correct Answer Logic:

The partial correlation $r_{12.3}$ is defined as the Pearson correlation between the residuals $X_{1.3} = X_1 - \hat{X}_{1|X_3}$ and $X_{2.3} = X_2 - \hat{X}_{2|X_3}$. This removes the linear influence of $X_3$ from both $X_1$ and $X_2$ before computing their correlation.

Question 2091

The biologically active hormonal form of vitamin D is:

Calcitriol✔️
Calmodulin
Retinol
Calciferol

Correct Answer Logic:

Calcitriol ($1,25\text{-dihydroxycholecalciferol}$ or $1,25(\text{OH})_2\text{D}_3$) is the biologically active hormonal form of vitamin D. It is produced by two-step hydroxylation: first in the liver (25-hydroxylation → calcidiol) and then in the kidney (1α-hydroxylation → calcitriol). Calcitriol acts on intestine, bone, and kidney to regulate calcium and phosphate homeostasis. Calciferol is the general term for vitamin D₂/D₃; retinol is vitamin A.

Question 2098

What are the primary oxides produced when Lithium ($Li$), Sodium ($Na$), and Potassium ($K$) are burned in an excess of air, respectively?

$LiO_{2}$, $Na_{2}O_{2}$ and $K_{2}O$
$Li_{2}O_{2}$, $Na_{2}O_{2}$ and $KO_{2}$
$Li_{2}O$, $Na_{2}O_{2}$ and $KO_{2}$✔️
$Li_{2}O$, $Na_{2}O$ and $KO_{2}$

Correct Answer Logic:

When burned in excess air:

Lithium forms the normal oxide ($Li_{2}O$).
Sodium forms the peroxide ($Na_{2}O_{2}$).
Potassium (and larger alkali metals) forms the superoxide ($KO_{2}$).

This variation is due to the increasing size of the cation stabilizing larger anions.
