Eye movement control during reading: II. Frequency of refixating a word

An analysis of over 40,000 eye fixations made by college students during reading indicates that the frequency of immediately refixating a word following an initial eye fixation on it varies with the location of that fixation. The refixation frequency is lowest near the center of the word, positively accelerating with distance from the center. The data are well fit by a parabolic function. Assuming that refixation frequency is related to the frequency of successful word identification, the observed curvilinear relation results naturally from models that postulate a linear decrease in visual information with retinal eccentricity. A single letter difference in fixation location in a word can make a sizeable difference in the likelihood of refixating that word. The effects of word length and cultural frequency on the frequency of refixating are also examined.     

Development of the Correspondence Between Real and Imagined Fine and Gross Motor Actions

The development of the correspondence between real and imagined motor actions was investigated in 2 experiments. Experiment 1 evaluated whether children imagine body position judgments of fine motor actions in the same way as they perform them. Thirty-two 8-year-old children completed a task in which an object was presented in different orientations, and children were asked to indicate the position of their hand as they grasped and imagined grasping the object. Children’s hand position was almost identical for the imagined- and real-grasping trials. Experiment 2 replicated this result with 8-year-olds as well as 6-year-olds and also assessed the development of the correspondence of the chronometry of real and imagined gross motor actions. Sixteen 6-year-old children and seventeen 8-year-old children participated in the fine motor grasping task from Experiment 1 and a gross motor task that measured the time it took for children to walk and imagine walking different distances. Six-year-olds showed more of a difference between real and imagined walking than did 8-year-olds. However, there were strong correlations between real and imagined grasping and walking for both 6- and 8-year-old children, suggesting that by at least 6 years of age, motor imagery and real action may involve common internal representations and that motor imagery is important for motor control and planning.     

Do Self-efficacy Expectation and Spirituality Provide a Buffer Against Stress-Associated Impairment of Health? A Comprehensive Analysis of the German Pastoral Ministry Study

We aimed to analyse stress perception, psychosomatic health and life satisfaction in pastoral professionals, paying particular attention to their individual and shared resources. Enrolling 8574 German pastoral professionals (48 % priests, 22 % parish expert workers, 18 % pastoral assistants, 12 % deacons), we found that pastoral professionals’ stress perception is associated with psychosomatic health impairment. General self-efficacy was a beneficial resource to protect against stress perceptions, while perception of the transcendent had a further yet weakly positive influence for stress-related impairment of health. External stressors (i.e. team size, duration of work per week and size of pastoral unit) were only of marginal independent relevance.     

Adynamic Aphasia: A Transcortical Motor Aphasia with Defective Semantic Strategy Formation

Adynamic aphasia is a form of transcortical motor aphasia characterized by sparse but otherwise normal spontaneous speech that may improve when concepts are introduced by external stimuli. Akinesia, impaired concept formation, inertia of concept generation, a defective semantic network, damage or impaired access to the verbal output lexicon, and defective semantic strategy formation have been proposed to account for this disorder. We studied a patient with adynamic aphasia and frontal lobe systems dysfunction due to bilateral striatocapsular infarctions. The patient was not akinetic but did demonstrate inertia of concept generation that could be overcome with prompting. However, prompting did not improve the number of concepts generated. He demonstrated a generally intact verbal lexicon and semantic network and normal lexical priming. However, his ability to sort closely related items into different classes without prior cuing regarding the nature of the classes was defective. Although his verbal memory was normal, he appeared to use a serial rather than a semantic strategy to recall items. Finally, despite normal lexical priming, he was impaired on a letter fluency task. These results most clearly demonstrate a defect in semantic strategy formation but indicate an additional and possibly related deficit in concept formation and a partial deficit in lexical strategy formation. All of these deficits appear to reflect impairment in the hierarchical organization of knowledge specific to the task at hand. This appears to be a key component of executive functions supported by frontal lobe systems.     

Associative and categorical processes in children's memory: The role of automaticity in the development of organization in free recall

Free recall performance was assessed in children in Grades 3, 5, 7, and 9 (Experiment 1) and adults (Experiment 2) on a list of categorically related words constructed so that some items within a category were highly associated with one another and interitem associations were low among other items (e.g., dog, cat, cow, lion, tiger). Associative relations were used frequently in recall by subjects of all ages, with analyses of interitem latencies and correlations between recall and clustering indicating that organization in recall was based only on associative relations for the third and fifth graders but based on both associative and nonassociative categorical relations for older subjects. Examination of the placement of high associates in recall indicated that seventh- and ninth-grade children were more apt to use associative relations to begin category clusters than were younger children or adults. These children were hypothesized to use the relatively automatic activation of associative relations to instigate categorical organization and to represent a stage in development between nonstrategic younger children and strategic adults. The results were discussed in terms of the role that the automatic activation of semantic memory relations may play in the development of strategic memory organization.     

Multiple incentives in encouraging car pool formation on a university campus

The effects of a combined token economy and reserved parking program were evaluated as a means of increasing car pooling among students on a university campus. Following a baseline period, students in two experimental parking lots were notified of the availability of reserved parking and coupons redeemable for 25 cents in merchandise for each occupant of automobiles containing two or more people. Two control lots also were monitored for a comparison of treatment effects. Results indicated variable increases in car pooling in the two experimental lots and no increase in the control lots. Removal of the 25-cent coupons from one treatment lot (reserved parking only) did not adversely affect rates of car pooling. An analysis of individual automobile occupancy rates among car poolers indicated distinct patterns of car pooling and underscored the importance of individual subject data analysis in the present situation. A cost-benefit analysis indicated that even moderately effective car pool programs can be cost-effective on both a public and personal level.     

Toward the clarification of the construct of depersonalization and its association with affective and cognitive dysfunctions.

Little consensus or systematic research exists regarding the symptoms that constitute depersonalization and its association with affective and perceptual dysfunctions. A scale was constructed to measure depersonalization experiences reported in the literature and four items representing psychotic symptoms. Five factors representing different types of depersonalization emerged: Inauthenticity, Self-Negation, Self-Objectification, Derealization, and Body Detachment. Based on the factors, scales were constructed; these scales have internal consistency ranging from .78 to .84. Each of these factor scales was factorially distinguishable from psychosis and correlated between .48 and .58 with the Jackson and Messick (1972) Feelings of Unreality Scale, suggesting divergent and convergent validity. Inauthenticity, the most frequent and pervasive form of depersonalization experience, was best predicted by a cognitive style featuring intense, critical examination of self and others. In contrast, Self-Objectification was best predicted by thought disorganization and perceptual distortion and was experienced somewhat infrequently by relatively few subjects. All forms of depersonalization were associated with depression, except Inauthenticity.     

Influence of a Photograph on a Charitable Appeal: A Picture May Be Worth a Thousand Words When It Has to Speak for Itself

Several studies were conducted examining the influence of the use of photographs of a needy individual on a charity appeal for either a well-known or lesser-known charity organization. Results of an initial study indicated that people expected the use of a photograph to enhance the effectiveness of a door-to-door solicitation campaign and that a well-known charity would fare better than a lesser-known one in its efforts. Results of two subsequent studies involving door-to-door solicitations, however. indicated that the proportion of people contributing and the average amount contributed was not dependent upon either the photograph or familiarity with the charity. A final study using a passive countertop solicitation in stores did result in greater contributions when the photograph was present, whereas there was no difference due to charity familiarity. These findings are discussed in terms of image-maintenance concerns and social pressures associated with the immediacy of a request.
