Skinner's assessment techniques include

A) free association.
B) dream analysis.
C) projective techniques.
D) laboratory experiments.

Skinner's assessment techniques involve laboratory experiments that are conducted in a controlled environment to observe the behavior of the subject. Skinner believed that behavior could be understood by observing and analyzing the observable and measurable responses of an organism to specific environmental stimuli. Therefore, experiment-based assessment techniques were core to his approach. The other options, free association, dream analysis, and projective techniques, are associated with psychoanalytic and psychodynamic assessment methods, which are not within Skinner's theoretical framework.
