Line spacing in Mondrian paintings and computer-generated modifications

Students compared computer-generated pictures of which 1 had line spacing and orientation proportional to that in a Mondrian picture (Mondrian-like), and 9 had divergent line spacing (divergently spaced). Preference was above average for the Mondrian-like picture compared with that for the divergently spaced pictures. However, participants did not prefer the Mondrian-like picture to divergently spaced pictures that were preselected as aesthetically pleasing by other participants. The results of the present experiments suggest that a computer algorithm can be developed to modify a picture in a way that is comparable with the way in which humans modify a picture to obtain a preferred picture. If aesthetic appeal is used in the storage and retrieval of visual information, then the algorithm could provide a better understanding of human perceptual processes. The results are related to consistency of aesthetic judgments across participants, levels of processing, and apparent contrast effects.     

A case study of mediated learning, delayed auditory feedback, and motor repatterning to reduce stuttering

A case study of DW, an 11-yr. old monolingual, English-speaking boy who exhibits stuttering, language delay, and ADHD is presented. DW experienced only limited improvement during stuttering therapy received in public schools, according to parents and the public school clinician. The purpose of this case study was to assess whether fluency treatment which incorporated Mediated Learning, Delayed Auditory Feedback, and Speech Motor Repatterning would enhance progress. Therapy was delivered in two treatments, with each treatment being 5 wk. of intense therapy, separated by one year. Treatment 1 of combined Mediated Learning and Delayed Auditory Feedback yielded improvement in fluency, judged by parents and the teacher to be clinically significant. The improved fluency was maintained for one year when DW was pretested for participation in Treatment 2, which combined Mediated Learning, Delayed Auditory Feedback, and Speech Motor Repatterning Exercises. As no conclusions are possible, further study is needed.     

A Review of the Children’s Inventory of Anger (ChIA): A Needed Measure

A review and critique of the Children’s Inventory of Anger (ChIA) is presented. The ChIA is a 39-item measure that operationalizes anger according to the conceptualization set forth by Ellis in Rational Emotive Behavior Therapy. The ChIA consists of four subscales (Frustration, Physical Aggression, Peer Relationships, and Authority Relations) which provide information regarding situations that are commonly associated with the experience of anger. Preliminary validity studies demonstrate that the ChIA has excellent reliability and high face validity. The forms are user friendly and easily scored, with norms tables conveniently located within the form. A computer-scoring program is available which significantly reduces clerical errors. The application of the instrument in practice is discussed. Due to the fact that the ChIA attempts to link assessment and intervention it should be useful in advancing the field in regard to treatment evaluation and substantiation of treatment validity. It is also expected to have considerable research utility.     

Recognition by humans and pigeons of novel views of 3-D objects and their photographs

Humans and pigeons were trained to discriminate between 2 views of actual 3-D objects or their photographs. They were tested on novel views that were either within the closest rotational distance between the training views (interpolated) or outside of that range (extrapolated). When training views were 60 degrees apart, pigeons, but not humans, recognized novel views of actual objects better than their pictures. Further, both species recognized interpolated views of both stimulus types better than extrapolated views, but a single distinctive geon enhanced recognition of novel views only for humans. When training views were 90 degrees apart, pigeons recognized interpolated views better than extrapolated views with actual objects but not with photographs. Thus, pigeons may represent actual objects differently than their pictures.     

Amygdala activation to sad pictures during high-field (4 tesla) functional magnetic resonance imaging

Fear-related processing in the amygdala has been well documented, but its role in signaling other emotions remains controversial. The authors recovered signal loss in the amygdala at high-field strength using an inward spiral pulse sequence and probed its response to pictures varying in their degree of portrayed sadness. These pictures were presented as intermittent task-irrelevant distractors during a concurrent visual oddball task. Relative to neutral distractors, sad distractors elicited greater activation along ventral brain regions, including the amygdala, fusiform gyrus, and inferior frontal gyrus. In contrast, oddball targets engaged dorsal sectors of frontal, parietal, and cingulate cortices. The amygdala's role in emotional evaluation thus extends to images of grief and despair as well as to those depicting violence and threat.     

Relationships between physical activity and motor skills in middle school children

The purpose of this study was to examine the relationships between physical activity measured as pedometer steps and performance on three motor skill tests. A secondary purpose was to determine if middle school children are meeting the recommendation for the number of daily steps. A sample (n =217) of 6th, 7th and 8th grade students participated. Each subject wore a Digi-Walker pedometer for three consecutive days. Subjects additionally recorded their pedometer steps in two 45 min.-physical education classes. There were strong significant correlations between daily steps taken by boys and girls, pedometer steps during physical education class and the AAHPERD Passing Test and the Bass Stick Balance. Similar correlations were weaker for the Side-Step Agility Test. Multivariate analysis of variance was utilized to examine variability of the three skills test by sex and year in school. Differences between students in Grades 7 and 8 on the AAHPERD Passing Test were significant. In addition, significant differences between daily pedometer steps and steps during physical education between Grades 6 and 7 were observed. Boys and girls had similar means on the AAHPERD Passing Test and Bass Stick Balance Test, but not on the Side-Step Agility Test. Scores on the three movement skills tested in this study were not strongly related to physical activity of the entire sample. Steps taken by middle school children appear not to be related to these measures of motor skills.     

Career benefits associated with mentoring for protégeé: a meta-analysis

Meta-analysis was used to review and synthesize existing empirical research concerning the career benefits associated with mentoring for the protégé. Both objective (e.g., compensation) and subjective (e.g., career satisfaction) career outcomes were examined. Comparisons of mentored versus nonmemored groups were included, along with relationships between mentoring provided and outcomes. The findings were generally supportive of the benefits associated with mentoring, but effect sizes associated with objective outcomes were small. There was also some indication that the outcomes studied differed in the magnitude of their relationship with the type of mentoring provided (i.e. career or psychosocial).
