Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Sex-linked Disorders01:43

Sex-linked Disorders

108.7K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Nuclear Binding Energy02:13

Nuclear Binding Energy

14.8K
The difference between the calculated and experimentally measured masses is known as the mass defect of the atom. In the case of helium-4, the mass defect indicates a “loss” in mass of 4.0331 amu – 4.0026 amu = 0.0305 amu. The loss in mass accompanying the formation of an atom from protons, neutrons, and electrons is due to the conversion of that mass into energy that is evolved as the atom forms. The nuclear binding energy is the energy produced when the atoms’ nucleons are bound...

The Equilibrium Binding Constant and Binding Strength02:18

The Equilibrium Binding Constant and Binding Strength

15.0K
The equilibrium binding constant (Kb) quantifies the strength of a protein-ligand interaction. Kb can be calculated as follows when the reaction is at equilibrium:

Velocity of an Object01:18

Velocity of an Object

199
Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

Conserved Binding Sites01:49

Conserved Binding Sites

5.2K
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Area of Science:

  • Cognitive psychology
  • Neuroscience
  • Human behavior

Background:

  • Object-location binding memory is crucial for everyday navigation and recall.
  • Understanding sex differences in memory performance can inform cognitive theories.
  • Cognitive load is a known factor influencing memory capabilities.

Purpose of the Study:

  • To investigate sex differences in object-location binding memory.
  • To examine the influence of cognitive load on these sex differences.

Main Methods:

  • Utilized the 'What was where?' task with fractal objects.
  • Manipulated cognitive load by varying the number of objects presented (3-4 vs. 4-5).
  • Assessed object memory, location memory, and object-location binding memory.

Main Results:

  • Females demonstrated superior performance in object-location binding memory compared to males.
  • Males exhibited a significant increase in swap errors under higher cognitive load (Session 45) compared to females.
  • This difference in swap errors persisted even when comparing trials with an identical number of objects but varying cognitive load.

Conclusions:

  • Significant sex differences exist in object-location binding memory.
  • Males may be more susceptible to the effects of increased cognitive load than females.
  • These findings contribute to understanding the nuanced interplay of sex, cognition, and memory.
