Psychological Laboratory for Individual Experiments

The psychological laboratory is equipped to serve two primary purposes:

1. Recording behavior and monitoring mental and emotional states, and
2. Systematic control of environmental and individual factors that influence and determine human mental and emotional conditions.

Experiments in this laboratory are designed to examine how behavior and internal states (dependent variables) relate to preceding or accompanying environmental and individual factors (independent variables). These experiments are typically conducted with individual participants, and data is collected over successive experimental sessions for analysis.

One major class of dependent variables is behavioral data, which primarily includes the speed and quality of performance in various achievement tasks. These tasks might assess:

• Learning (e.g., reproduction of texts),
• Perception (e.g., estimating distances),
• Problem-solving (e.g., navigating a maze),
• Sensorimotor actions (e.g., responding to a light signal).

In addition to performance measurement, behavioral records can indicate habitual or transient mental and emotional states, such as fatigue, positive effect, or surprise. For example, facial expressions can provide observable cues to emotional reactions. Furthermore, behavioral data may reflect stable personality traits, including self-efficacy, anxiety, and social withdrawal.

Another essential class of dependent variables includes self-reports, where participants provide insights into their judgments, mental processes, and subjective experiences.
