Counter conditioning procedures reduced text anxiety in fifth and sixth grade children and improved their Digit Span performance but not Vocabulary performance on the Wechsler Intelligence Scale for Children. (Author/DEP)

A nurse involved with institutionalized retarded children analyzes the value of behavior modification and describes four behavior modification programs planned and carried out by nursing staff to modify food stealing, screaming at mealtimes, excessive requests for self assurance, and unitary incontinence.

Examined the differential effects of reinforcement versus extinction in contingency management of outpatient unipolar depression for depressed subjects (N=6) and their significant others. Supports the efficacy of contingency management. (Author/ABB)

Relationship between maternal ratings of temperament and operant learning was examined in 18 2- to 3-month-old infants. Subjects participated in a conjugate reinforcement experiment; mothers of subjects completed the Carey and McDevitt Revised Infant Temperament Questionnaire 2 to 3 days before the learning study. Two temperament dimensions,…

Presented is a case study of a 19-year-old female with hydraencephaly (a condition marked by excessive accumulation of fluid in the cerebral ventricles) who was conditioned on three occasions to increase eyeblink rate with tactile reinforcement. (CL)

Five components of learning motivation delineated are: (1) expectations of positive affective change; (2) self concept; (3) goal setting; (4) knowledge of steps instrumental to learning; and (5) self evaluation. Cultural differences on these components are also discussed. (RP)
