Electroencephalographic value of acoustic stimulation within the scope of the diagnosis of forms of cerebral seizure in childhood and adolescence

In this report we represent the phone-stimulation as an important method of provocative to activate the bioelectric potentials of brain, if epileptic seizures will be appeared in age of childhood and youth. The method ist able to demonstrate irritations of the reticulothalamic system. The information on the activity of the substantia reticularis will be demonstrated by the bioelectric reaction under phone-stimulation.     

Personal constructs, performance schemata, and “folk theories” of subordinate effectiveness: Explorations in an army officer sample

This research employs personal construct theory (Kelly, 1955)to explore the content of categories or schemata that may be used in making work performance judgments. Twenty-five experienced U.S. Army officers, focusing on the job of noncommissioned officer (NCO; first-line supervisor), generated independently a total of 189 personal work constructs that they believe differentiate between effective and ineffective NCOs. The officer subjects numerically defined each of their own 6–10 constructs by rating the similarity between each of these constructs and each of 49 reference performance, ability, and personal characteristics concepts. Correlations were computed between the subject-provided similarity ratings for the constructs, and the 189 × 189 matrix was factor analyzed. Six interpretable content factors were identified (e.g., Technical Proficiency, Organization), with 123 of the 189 constructs from 23 of the 25 subjects loading substantially on these factors. Findings here suggest that a core set of concepts is widely employed by these officers as personal work constructs, but that different officers emphasize different combinations of this core set. The personal constructs elicited from officer subjects are likened to performance schemata and “folk theories” of job performance.     

Kinetic attraction during bimanual coordination

Two experiments examined the effects of independent variations in kinetic and kinematic requirements on interlimb coupling during a bimanual task. The goal of the investigation was to provide preliminary evidence regarding one general class of physical variables that constrains discrete bimanual movements. Subjects attempted to execute a smooth unidirectional movement with the left arm, along with a three-segment reversal movement with the right arm. The first experiment manipulated the torque required to produce the reversal action, while movement duration and average angular velocity were held constant for both limbs. Several indications of increased interlimb coupling, due to the kinetic variation, were evident. The converse manipulation was used in the second experiment, with movement time and kinematics (velocity, acceleration) changed independently of joint torque requirements for the reversal limb. No clear effect of kinematics on coupling strength was noted. The results suggest that one variable influencing interlimb attraction toward common spatiotemporal trajectories may be kinetic in nature.     

Identification of vowels in “vowelless” syllables by 3-year-olds

The ability of 3-year-old children to perceive the identity of vowels in full-vowel and silentcenter, consonant-vowel-consonant (CVC) syllables was investigated using a two-alternative pointing procedure. Silence replaced the middle 10%, 35%, 65%, or 90% of the steady-state formants of synthetic “bad” and “bud” syllables. Identification of the two full-vowel syllables was 87% correct, whereas performance for the silent-center syllables was somewhat lower (72%, 70%, 67%, and 66% correct for the 10%, 35%, 65%, and 90% deletion stimuli, respectively). The performance of individual children fell into two subgroups: (1) those who performed like adults by maintaining correct vowel identification for all of the silent-center syllables, and (2) those who identified the full-vowel syllables correctly but performed at chance for all of the silent-center syllables. Three additional experiments showed that none of the children performed poorly when noise replaced the gap in the silent-center syllables. These results demonstrate that many 3-year-olds can identify vowels correctly in CVC syllables in the absence of the full spectral properties of steady-state formants.     

Sensory and conceptual representations in memory: Motor images that cannot be imaged

Summary The paper argues for a distinction between sensory-and conceptual-information storage in the human information-processing system. Conceptual information is characterized as meaningful and symbolic, while sensory information may exist in modality-bound form. Furthermore, it is assumed that sensory information does not contribute to conscious remembering and can be used only in data-driven process reptitions, which can be accompanied by a kind of vague or intuitive feeling. Accordingly, pure top-down and willingly controlled processing, such as free recall, should not have any access to sensory data. Empirical results from different research areas and from two experiments conducted by the authors are presented in this article to support these theoretical distinctions. The experiments were designed to separate a sensory-motor and a conceptual component in memory for two-digit numbers and two-letter items, when parts of the numbers or items were imaged or drawn on a tablet. The results of free recall and recognition are discussed in a theoretical framework which distinguishes sensory and conceptual information in memory.     

The effects of interactive staff training on staff programing and patient aggression in a psychiatric inpatient ward

Interactive staff training (IST) uses principles of organizational psychology to help line-level staff members design and implement social learning programs for severely mentally ill inpatients. IST is a training package that includes assessment of staff perceptions regarding programatic needs, selection of appropriate social learning strategies to meet these needs, appointment of a program committee from within the ward to champion development of the social learning strategy, and participative decision making about aspects of the social learning strategy. Staff on an extended care ward at a state hospital participated in IST for 15 months as part of a pilot study of its effects. Ongoing examination of ward programing showed that IST significantly increased staff and patient participation in rehabilitation programing and decreased the rate of physical restraints and aggression-related. Changes in staff attitudes about rehabilitation programing were noted on a subsample of IST participants. Implications for more controlled research into IST are discussed.
