Icelandic and American Students' Expectations About Counseling

The Expectations About Counseling‐Brief Form (H. E. A. Tinsley, 1982) was administered to 261 Icelandic and 225 American undergraduates. A 2 (Nationality: Icelandic & American) x 2 (Sex: men & women) x 3 (Holland Type: A, S, E) between subjects multivariate analysis of covariance (MANCOVA) was calculated with prior counseling experience as a covariate and expectations about counseling as dependent variables. Icelanders had higher expectations about counselor expertise than did Americans. In addition, women expected to be more personally committed in counseling than did men. Results are discussed in terms of counselor roles and functions and the role of help seeking in Iceland.     

Orientation tuning of shapefrom shading

Four experiments were performed to assess the effect of different orientations and direction of lighting on the visual processing of shaded or bipartite disks. In the first two experiments, observers were presented with nine different shading orientations from 0° to 180°. Targets were detected in a rapid and parallel fashion for shaded disks when the orientation of the shading gradient was not horizontal (90°) or oriented at 67.5°. Search asymmetries favoring the detection of “pock” targets over “ball” targets were found for all orientations. The search rates for bipartite disks were similar to the shaded disks at 0°, 22.5°, and 90° but not for intermediate orientations, and no search asymmetries were found. These differences suggest that shaded displays and bipartite displays are processed by different underlying mechanisms. The third experiment showed that the direction of the light source (left or right) had no influence on search asymmetries around the 90° point. Shading gradient orientation affected magnitude estimates of depth in the fourth experiment. These experiments show that the visual system’s “as-sumption” of overhead lighting is broadly tuned.     

Time perception in boys with attention-deficit/hyperactivity disorder according to time duration, distraction and mode of presentation.

In a recent theoretical model of attention-deficit/hyperactivity disorder (ADHD), Barkley (1997a) predicted that ADHD children experience impairments in their psychological sense of time. This was demonstrated in a series of experiments by Barkley, Koplowicz, Anderson, and McMurray (1997). The present study sought to investigate the effects of ADHD subtype, stimulus duration, mode of presentation (visual versus auditory) and distractors on the performance of a simple time reproduction task. Data were obtained from 44 ADHD children (14 predominantly inattentive and 30 combined type) and 44 age-matched Controls using the Time Perception Application version 1.0 (Barkley, University of Massachusetts Medical Center, 1998). Results revealed that the ADHD children made significantly larger errors on Visual time reproduction tasks than the Controls, regardless of ADHD subtype or the presence of distractors. Furthermore, ADHD children were more likely to overestimate the shorter time intervals (0.5 and 2 s) and underestimate the longer time intervals (3, 4 and 6 s) relative to Controls. No group differences were observed on the auditory time reproduction task, with both ADHD and Control groups consistently underestimating the durations to be reproduced. The results of this study provide further support for the prediction that children with ADHD have an impaired sense of time.     

Health-related behavior and beliefs of pregnant smokers.

To determine the association of smoking with other health-compromising behavior and beliefs during pregnancy, a cross-sectional survey of 1,203 women in the United Kingdom assessed smoking status, stage of change, fetal health locus of control, alcohol consumption, folic acid intake, and use of vitamin and iron supplements. Twenty percent were current smokers, and 33% were alcohol users. Pregnant smokers (especially those in the precontemplative stage) were less likely to increase folic acid intake, less likely to take vitamin and iron supplements, and less likely to feel personally responsible for the health of the fetus. Infants of smokers may be placed at an intrauterine disadvantage, not only in terms of smoking, but also in terms of nutrition.
