Before And After

In the scope of studies that investigate the effects of manipulation in verbal antecedents upon the related non verbal behavior, the present study evaluated the effect of differential reinforcement of one response class (choice of phrases about positive aspects about reading, interpreted as tacts with positive qualifying autoclitics) upon other class (the choice of reading behavior), reinforcing choices of phrases about positive aspects of reading and observing its effects upon the emission of reading behavior. It were registered activities and photographs chosen before and after the training. During training, four phrases appeared in a computer screen and just the choice of one of them (related to reading) was reinforced with points. The results indicated an augment of the choices in reading behavior as well as in the time of reading for the majority of the participants and an augment of the choices of choosing photographs related to reading, when compared to the results of the baseline. The results are interpreted according to behavior verbally governed.

In the first study 125 Ss representing four birth-order groups participated in an interview during which a preselected response class (positive or negative self-statements) was reinforced. In the second study 40 Ss representing four birth-order groups participated in a series of six interviews during which E reinforced the preselected response class (positive or negative self-statements). There were no significant differences among birth-order groups in responsiveness to differential reinforcement of evaluative self-statements. Particularly, firstborns did not show the responsiveness to social influence which reportedly characterizes them. Findings were discussed in the context of the need for replications.

<p>Conceptual metaphor theory posits that the physical domain (e.g. the vertical dimension) is used to understand abstract concepts (e.g. affect); creating expressions such as, “falling into a deep depression.” Previous research concerning vertical metaphors has found that people more rapidly process positive and negative words when the valence was metaphorically consistent with vertical position (Meier & Robinson, 2004) and that mood traits were metaphorically consistent with vertical attentional biases (Meier & Robinson, 2006). The purpose of the current study was to investigate the effects of vertical perceptual biases on mood; whether shifting perception could have an effect upon the emotional experience of an individual. In Experiment 1, vertical attention was manipulated by having university students move letters upwards or downwards on a computer screen, with measures of mood completed before and after the manipulation. In Experiment 2, participants completed the same task, but moved schematic faces that were either happy or sad. In both experiments vertical attention was biased; however a significant change in mood state was produced only when schematic faces were used as stimuli in the task. The results suggest that shifting an individual’s vertical perception can influence their mood, when the task is emotionally arousing.</p>

Emotional Words

Reinforcement and other experimental manipulations may influence the content as well as the frequency of verbal behavior. Evidence was presented from five studies ( N = 283) in which emotional words, EW, were reinforced in TAT-like situations. EW used during reinforced trials were pleasanter than those used during operant trials; differential experimental manipulations led to differential pleasantness of EW; pleasantness of EW used during operant trials was significantly associated with personality test measures, particularly anxiety and hostility. The results bear on the role of reinforcement in social influencing situations and provide an additional measure of the effect of reinforcement.

Objectives: Computer usage has rapidly grown. This is because it helps to resolve problems, i.e., encountered in daily life by individuals. Various monitor screens that have been developed affect the user’s eyes. Screen size is one of the relevant impacts. Thus, this study compared the immediate effects of two computer screen sizes on visual fatigue in Video Display Terminal (VDT) users. Methods: Twenty female VDT users participated in this study. Using a randomized block design for the study, the study participants randomly drew a ballot to determine the order of using an 18.5-inch and 23-inch computer screen size. The research participants were assessed by a visual fatigue score, critical flicker frequency, and dry eye score before and after using both computer screen sizes. They were tested in an ergonomic computer workstation for 2 hours. Besides, where they rested between each workstation for ≥30 minutes or until presetting no eye fatigue symptoms. The relevant data were compared between before and after using the computers and between the two different screen sizes. Results: The collected results suggested no significant difference in the visual fatigue score, critical flicker frequency, and dry eye score between using either computer screen sizes (P>0.05). However, there were significant differences in the visual fatigue score, critical flicker frequency, and dry eye score between before and after computer screen usage (P<0.05). Discussion: Using both computer screen sizes resulted in increased visual fatigue, reduced critical flicker frequency, and increased dry eyes. The present study results can provide information in determining how to reduce risk factors and prevent visual fatigue from continuous computer use for a long time.

Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.
