The Contextual Interference Effect

Contextual Interference (CI) occurs when multiple skills are practiced concurrently, causing interference between the tasks. This increased difficulty results from introducing three or more distinct tasks within the same practice session.

• Low CI: Typically achieved through blocked practice (performing all repetitions of one task before moving to the next).
• High CI: Typically achieved through random practice (interleaving different tasks unpredictably).

Impact on Learning and Performance

The CI effect demonstrates that introducing greater levels of interference into the practice setting enhances a learner's ability to remember skill-related information long term, although it may negatively affect short-term performance...

Introduction to OB

Organisational behaviour is more about individual and team

Human are easy to deceive

Intuition can be wrong

Organisational culture

Definition: It is the shared set of beliefs, expectations, values, norms, and work routines that influence how members of an organization relate to one another and work together to achieve organizational goals.

7 dimension of organizational culture

Innovation/Stability/Respect for people/Outcome orientation/Attention to detail/Team orientation/Aggressiveness

Variability in culture is low than the relationship between outcome and culture is clear

Importance of a strong organisational culture

Organisational identity (like sense of belonging)/Sense-making device/Collective commitment/Social system stability... Continue reading "Understanding Organisational Behaviour and Leadership" »

Ethical Considerations in Psychological Research

One ethical consideration in psychological research is the use of deception. Deception occurs when a participant is not made fully aware of the purpose of a study or is intentionally misinformed. Researchers often use deception to hide the true aim of an experiment. If participants knew the aim, they might demonstrate demand characteristics, either trying to give the researchers what they want or behaving in a way that makes them look their best, a phenomenon known as the social desirability effect.

Deception is problematic because it undermines the concept of informed consent. It violates the trust between a researcher and a participant. Additionally, it increases the chance that a participant... Continue reading "Ethical Deception in Research & Multi-Store Memory Model" »

Cerebellum's Role in Learning

Thompson identified the lateral interpositus nucleus (LIP) in the cerebellum as crucial for learning. Blocking LIP activity during conditioning prevents learning responses. Studies confirm LIP's necessity for learning, retention, and extinction.

Types of Memory

Short-Term Memory

• For recent events, limited capacity.
• Fades quickly without rehearsal (around 20 seconds).

Long-Term Memory

• For older events, vast capacity.
• Can last for years, aided by cues.

Consolidation

Process of crystallizing short-term memories into long-term.

Working Memory (WM)

Brain system for temporary storage and manipulation of information for complex tasks (learning, reasoning). Requires simultaneous storage and processing, linked to prefrontal cortex... Continue reading "Cerebellum and Memory: LIP, Hippocampus, and Learning Processes" »

Performance Management and Appraisal

Understanding Performance Management

Performance management is a goal-oriented process that ensures the implementation of processes to maximize productivity at employee, team, and organizational levels. It emphasizes a close relationship between incentives and performance, operating as a dynamic, ongoing, and continuous process. Each component of the system is integrated and linked to achieve continuous organizational effectiveness.

Performance Appraisal

Performance appraisal is a formal system for reviewing and evaluating individual or team task performance. Various methods can be employed:

Traits

This method evaluates employees based on traits such as attitude, appearance, and initiative. However, caution is... Continue reading "Performance Management and Appraisal: A Comprehensive Guide" »

What is Socialization?

Socialization is the ongoing process by which we develop our sense of self and learn the ways of society.

Internalization

Internalization is the process by which people take in the values and norms that the agents of socialization are trying to instill.

Social Groups

Groups consist of two or more people who share an identity, feel a sense of belonging, and interact with each other. We can distinguish between:

• In-group: A group you belong to.
• Out-group: A group you do not belong to.

The Importance of Social Contact

Close contact with others is critical to our development. Strong social ties are linked to well-being, while social isolation is detrimental to humans. "Feral" children are an example of the negative effects of extreme... Continue reading "Understanding Socialization: Key Concepts and Theories" »
