History, systems, and applied psychology (foundations, professional issues, applications)

This domain tests the intellectual lineage of psychology and how psychology is practiced and regulated. Items often pair a founder with a school, or ask which applied method is defensible.

Foundations

  • Wilhelm Wundt founded the first psychology laboratory at Leipzig in 1879 and promoted introspection; Titchener brought structuralism to the United States; William James's functionalism asked what mental processes accomplish.
  • Gestalt psychology (Wertheimer, Koehler, Koffka) argued perception is organized wholes rather than sums of parts; the phi phenomenon was a key demonstration.
  • Behaviorism (Watson, Skinner) restricted psychology to observable behavior; psychoanalysis (Freud) emphasized unconscious conflict; the cognitive revolution of the 1950s and 1960s reopened internal processes, aided by information theory and Chomsky's critique of behaviorist accounts of language.
  • Humanistic psychology (Maslow, Rogers) formed a third force; positive psychology later emphasized strengths and well-being.

Applied areas

  • Industrial-organizational: job analysis drives selection. Structured interviews, work samples, and cognitive ability tests show higher criterion validity than unstructured interviews or graphology, and validity generalizes across jobs. Appraisal suffers from halo, leniency, and recency effects. The Hawthorne studies showed that being observed changes behavior.
  • Clinical versus counseling psychology (counseling typically addresses adjustment and less severe concerns); school, health, forensic, sport, and environmental psychology apply principles to systems. Human factors matches tools and tasks to human limits.

Professional issues

  • The APA Ethics Code has five aspirational principles (beneficence and nonmaleficence, fidelity and responsibility, integrity, justice, respect for people's rights and dignity) plus enforceable standards. Principles guide; standards bind.
  • Competence boundaries, multiple relationships, informed consent, confidentiality limits, test security and user qualifications, and record-keeping under HIPAA.
  • Licensure requires accredited training, supervised hours, and examinations; continuing education renews it. Prescription privileges remain limited and jurisdiction-dependent.

Worked example

A firm replaces unstructured interviews with a structured interview plus a work sample and a validated ability test. Reasoning: unstructured interviews have modest predictive validity, whereas structured interviews, work samples, and ability tests show higher criterion validity that generalizes across jobs, so expected performance improves; adverse impact must still be monitored under fair-employment rules.

Traps

Crediting James with founding the first laboratory; treating the five ethical principles as enforceable standards; assuming graphology or projective tests are valid hiring tools; answering trait or humanistic theory when an applied I/O question is asked.
