The study found that body postures, like faces, are perceived holistically. This means we process entire body poses at once, not just individual parts, similar to the face composite effect.
Area of Science:
- Cognitive psychology
- Vision science
- Human perception
Background:
- Human faces are processed holistically, not analytically.
- The face composite effect provides evidence for holistic face processing.
- This effect occurs when identical face halves appear different due to varying other halves.
Purpose of the Study:
- To investigate if a similar composite effect exists for body posture perception.
- To determine if body halves are perceived holistically.
- To test for horizontal and vertical body posture composite effects.
Main Methods:
- A delayed matching-to-sample task was employed.
- Experiment 1 examined horizontal composite effects (top-bottom body halves).
- Experiment 2 examined vertical composite effects (left-right body halves).
Main Results:
- A body posture composite effect was observed in both experiments.
- Identical body halves were perceived as different when paired with different irrelevant halves.
- This indicates holistic processing of body postures.
Conclusions:
- Body postures are processed holistically, similar to human faces.
- The findings support the hypothesis of holistic processing for body perception.
- This extends the understanding of holistic processing beyond facial stimuli.

01:09Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
