Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

95.4K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Golgi Apparatus01:49

Golgi Apparatus

102.5K
As they leave the Endoplasmic Reticulum (ER), properly folded and assembled proteins are selectively packaged into vesicles. These vesicles are transported by microtubule-based motor proteins and fuse together to form vesicular tubular clusters, subsequently arriving at the Golgi apparatus, a eukaryotic endomembrane organelle that often has a distinctive ribbon-like appearance.

Golgi Apparatus

Properly folded and assembled proteins are selectively packaged into vesicles that exit the ER. Motor proteins transport these vesicles to the Golgi apparatus for adding modifications that make these proteins functional at their destination.
The Golgi apparatus is a eukaryotic organelle that has a distinctive ribbon-like appearance. It is a primary sorting and dispatch station for cargo arriving from the ER. Newly arriving vesicles enter the cis face of the Golgi, closest to the ER, and are...

Generalization, Discrimination, and Extinction01:24

Generalization, Discrimination, and Extinction

1.4K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Testes: Histology01:27

Testes: Histology

3.0K
A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.
The spermatogenic cells, responsible for producing sperm, are...

Complementation Tests00:49

Complementation Tests

6.3K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Area of Science:

  • Animal Behavior
  • Cognitive Science
  • Comparative Psychology

Background:

  • Collecting reliable data in animal visual discrimination tasks can be challenging.
  • Observer error and lack of standardization can impact experimental validity.
  • Existing methods may require internet connectivity or be prohibitively expensive.

Purpose of the Study:

  • To introduce the Subject-Mediated Automatic Remote Testing Apparatus (SMARTA), an open-source system for visual discrimination tasks.
  • To demonstrate SMARTA's utility in streamlining data collection and reducing observer error in animal research.
  • To provide instructions for building and implementing SMARTA for experimental use.

Main Methods:

  • SMARTA utilizes a touchscreen interface for automated data collection without internet.
  • The apparatus is designed to be inexpensive, easy to build, and adaptable to various experimental designs.
  • A case study involving color vision in ruffed lemurs (Varecia spp.) was conducted to demonstrate functionality.

Main Results:

  • SMARTA successfully facilitated two-choice color discrimination tasks in ruffed lemurs.
  • The system demonstrated its ability to streamline and standardize data collection processes.
