Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

3.0K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Decision Making: P-value Method

7.2K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Decision Making01:20

Decision Making

1.2K
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Cognitivism

3.4K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Optimizing growth media enhances microbial proliferation and maximizes product yield. Statistical experimental design methodologies provide structured and reproducible approaches, offering progressively higher levels of robustness and efficiency.The One-Factor-at-a-Time (OFAT) MethodThe One-Factor-at-a-Time (OFAT) method involves adjusting a single variable while keeping all others constant. However, it cannot detect interactions between variables, often leading to suboptimal outcomes when...

Area of Science:

  • Psychology
  • Neuroscience
  • Behavioral Economics

Background:

  • Previous research highlighted communication's impact on trust and reciprocity in economic decisions.
  • However, the effect of communication on affective states within this context remained unexplored.

Purpose of the Study:

  • To investigate how different communication types influence affective states during economic decision-making.
  • To examine the relationship between personal versus impersonal communication, trust, reciprocity, and emotional responses.

Main Methods:

  • Utilized computational psychometrics with simultaneous, synchronized recordings of gazes and psychophysiological signals.
  • Conducted an investment game with 28 female students, varying communication conditions (personal vs. impersonal).

Main Results:

  • Participants exhibited distinct affective states based on communication type, with personal communication leading to greater relaxation.
  • Personal communication positively influenced reciprocity and perceptions of trust.

Conclusions:

  • Communication style significantly impacts emotional experiences and decision-making in economic contexts.
  • Findings align with the Arousal/Valence Model and self-disclosure theories, underscoring the importance of personal interaction.
