Exploring the IB Psychology syllabus provides a clear view of the skills and knowledge you'll acquire throughout the course. Join us as we unpack the key concepts of the syllabus, giving you a better understanding of what to expect on your learning journey.

Psychology

Both SL and HL students will explore biological, cognitive, and sociocultural approaches to understanding human behaviour through several key contexts:

Concepts

Researcher bias, participant bias sampling bias, confirmation bias, publication bias

Determinism (biological and environmental)

Credibility, reflexivity, inter-rater reliability

Bias

Correlation vs causation; bidirectional ambiguity

Validity: internal vs external validity; mundane realism

Controls: extraneous variables, placebos, double-blind, wait-listing

Causality

Use of longitudinal and repeated measures designs

Intervention, prevention and promotion strategies

Change

Constructs and variables; operationalization of variables

Types of data (self-reported, anecdotal, empirical)

Statistical significance; type I and type II errors

This part of the course is intended to be active and engaging for students, providing an opportunity for them to be guided through a critical discussion of each approach to research.

All students must engage in a class practical for each context. These can be teacher and/or student led.

Furthermore, students can be encouraged to design and operate additional student-led class practicals.

While these extra exercises are not compulsory they must always be conducted with explicit permission from the teacher, given on a class practical research form (provided in the teacher support materials) and

All class practicals must follow ethical guidelines.

Further guidance on best practice for this aspect of the course will be provided in the Psychology teacher support material.

The extent to which learning and cognition across cultures are similar and different. conscious or unconscious level. Motives are frequently divided into primary motives, such as hunger, thirst and need for sleep, and secondary motives, such as affiliation, competition, and individual interests and goals. An important distinction must also be drawn between intrinsic (internal) motivation and extrinsic motivation, such as rewards or punishments, that can encourage or discourage certain behaviours. motivation to eat in people with eating disorders. For secondary motives, direct methods are often used, such as asking the individual why they engaged in certain behaviours. These methods are reliant on self- reported data and are open to demand characteristics. Experimental methods may also be used to test the effects of different external motivators. tendencies and innate psychological needs influence one’s choices in the absence of external influences.

Much research is correlational in nature, presenting the problem of bidirectional ambiguity when interpreting the findings. There is also a high potential for researcher bias or confirmation bias, especially in action research carried out in school settings. question of the funding of the research. Many researchers may make assumptions about the positive or negative influences of technology on behaviour and mental health. Findings from various studies have not been replicated, thus contributing to the replication crisis in psychology. Table 6.3 Contexts and learning objectives for technology problems.
