Role of visual acuity in tachistoscopic recognition of three-letter words

It has been suggested that a correlation between word recognition and visual acuity would constitute a confounding influence in word-recognition studies within a laterality paradigm. 20 Ss made binary judgments concerning the presence or absence of a spatial gap in a tachistoscopically presented line target positioned at .75°, 1.5°, 3.0°, and 6.0° in either visual field. Gap detection was superior in the right visual field ( p = .02) at the 6.0° position. Word recognition was determined for tachistoscopically presented three-letter words positioned along a 6.0° vertical meridian in either visual field. Visual acuity performance was not related to word recognition either for the group or for individual Ss. The data therefore do not encourage the view that normal variations in acuity significantly affect word recognition in laterality studies.

Recovery of function after serial ablation of prefrontal cortex in the rhesus monkey

Rhesus monkeys with one-stage or serial ablation of sulcus principalis (prefrontal association cortex) were compared on three spatial tasks. On all tests, the serial monkeys made fewer errors than did the monkeys with onestage lesions. These results indicate that partial recovery of function can occur after extensive destruction of association cortex in the mature primate brain if the damage is distributed over a number of operations.

Interanimal "memory" transfer: results from brain and liver homogenates

Sixty mice received either shock or no shock in a shuttle box, or nonspecific stress in another apparatus. Brain and liver homogenates from these animals were then injected into 120 naive recipients, who were all tested in the shuttle box. Subjects receiving brain or liver from shocked or stressed donors had significantly higher latencies than control counterparts. These results are interpreted in terms of stress, rather than a memory transfer hypothesis.

School counselor dogmatism and vocational identity

23 school counselors were ranked according to scores on the Rokeach Dogmatism Scale. Rhos were computed between the Dogmatism Scale scores and the following scales: Opinionnaire on Attitudes Toward Education, Thurstone Interest Schedule's Executive and Humanitarian scale scores, and the Minnesota Teacher Attitude Inventory. No relationship between counselor rigidity and vocational identity (criterial measures) was observed.

Multiple-regression analysis of counselor characteristics and competencies

To investigate the predictive value of the counselor's personal characteristics which are associated with a counselor's initial and terminal competency 28 counselor trainees were rated on 2 counseling interviews at the beginning and 2 at the end of training on the following dimensions: Self-congruence, Unconditional Positive Regard, Accurate Empathy, and Total Competency. Their personal characteristics were measured at the beginning of training with the following: the Allport-Vernon-Lindzey Study of Values, the Social Service Group of the Strong Vocational Interest Blank for Men, the Edwards Personal Preference Schedule, the Dogmatism Scale D, the National Defense Education Act Examination in Guidance and Counseling, teaching experience, counseling experience, and age of counselors. The four best combinations of personal predictors were determined through multiple-regression analysis. It was concluded that this population of counselor trainees demonstrated no preferred characteristics in relation to competency factors.
