Effects of residential evaluation and rehabilitation placement on children's state-trait anxiety.

The recently developed State-Trait Anxiety Inventory for Children was used to explore the stress experienced by youngsters who were placed from home into a state residential setting for diagnostic evaluation or involvement in a rehabilitation program. Twenty-four youngsters, who ranged from 12 to 16 years, responded to the measure on admission day and 21 to 25 days postarrival. The proposition that trait anxiety would remain relatively stable across time (t = .64, p greater than .50) and the prediction that geographic isolation and new social controls initially would be experienced as ego-threatening (t = 3.24, p less than .01) clearly were supported. The results are viewed as support for the predictive validity and normative stabilility of the children's state-trait anxiety measure.

Learning disabilities and central nervous system involvement.

The relation of damage to the central nervous system to learning disabilities remains a continuing issue. This study explored how learning disable children fare on the Visual Retention Test. Analysis of correct scores and errors for the 24 children responding to Administration A would ordinarily suggest a primary relationship (t = 2.60, p less than .02; t = 4.01, p less than .001, respectively). However, since extensive medical and case history material yielded no evidence of cerebral injury or disease and since the impact of short-term memory (Administration D) led to no further performance decrement (t less than 1.00), additional research must determine a more precise understanding of perceptual dysfunction and the role of short-term memory in regard to learning disabilities.

Visual retention test: local norms and impact of short-term memory.

Issues related to assessment of organic impairment and to normative data underscore the importance of securing reliable criteria directly applicable to the population under question. This study explored the applicability of the Visual Retention Test norms to a local, nonorganically impaired population of young people and made a preliminary empirical evaluation of the time-delay format. The 23 males and 18 females ranging from 8 to 17 yr. and seen at a midwestern child guidance center responded to two administrations (A and D) of the Visual Retention Test embedded in a complete psychological test battery. The proposition that present-day local subjects would not differ from the normative group either by the number correct or number of errors (t = 1.02, p greater than .20; t = .83, p greater than .40, respectively), as well as the prediction that the time-delay format would effect a significant performance decrement with both scoring systems (t = 2.63, p less than .01; t = 4.40 p less than .001, respectively) were clearly supported.
