Genome Annotation and Assembly03:36

Genome Annotation and Assembly

21.1K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Role of Affect in Interpersonal Attraction01:24

Role of Affect in Interpersonal Attraction

240
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

The Influence of Affect on Cognition

307
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect

232
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Background and Environment Affect Phenotype

7.8K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Area of Science:

  • Psychology
  • Computer Science
  • Human-Computer Interaction

Background:

  • Subjective experience and observable behavior over time are crucial in various research fields.
  • Existing methods for capturing moment-by-moment affective responses can be cumbersome.
  • A need exists for intuitive tools to collect continuous, fine-grained data from multimedia stimuli.

Purpose of the Study:

  • To introduce CARMA, a novel media annotation program.
  • To provide a user-friendly and customizable platform for collecting continuous affect ratings.
  • To facilitate the capture and analysis of real-time subjective experiences during multimedia exposure.

Main Methods:

  • CARMA utilizes a rating dial interface, inspired by Gottman and Levenson's work.
  • Users can provide moment-by-moment ratings via mouse or keyboard input.
  • The rating scale is configurable in terms of labels, numerical range, and visual display.

Main Results:

  • CARMA allows for the collection of detailed, time-locked annotations synchronized with audio-visual media.
  • Annotations can be easily exported for statistical analysis.
  • The program is designed for high user-friendliness and customization.

Conclusions:

  • CARMA offers a valuable tool for researchers in affective computing, HCI, and social sciences.
  • It effectively captures the unfolding of subjective experience and behavior.
  • The program enhances the ability to study dynamic emotional and behavioral responses to media.
