Implications of measurement of eye fixations for a psychophysics of form perception

It was suggested that insights into feature analysis of processes involved in form identification might be gained from an analysis of eye movements made by Ss as they identified patterns. Fixations were measured during identifications of histoforms, polygons, and Vargus 10 figures. Eye fixations were measured, and Ss rated sections of the figures in terms of their importance. Eye fixations were measured in terms of number of changes and duration of fixations. The number of changes in fixation were found to reflect only individual differences. Duration of fixation was found to vary significantly with location within figures, with fixations being longest where changes of contour occurred. There was also a tendency to look longer at the top of polygons and Vargus 10 figures and at the center of histoforms. Ratings of importance were highest for sections of figures fixated for longer duration-generally areas in which changes of contour were present.     

A case of cortical deafness: Clinical and electrophysiological data

A patient suffering from a primary myocardiopathy is suddenly no longer able to recognize speech and environmental sounds, in spite of good peripheral hearing; he remains able to speak, read, and write. The C.T. scan shows lesions involving both supratemporal planes. The cortical sensory deficit documented by the absence of late acoustic evoked potentials leads to a diagnosis of cortical deafness rather than of auditory agnosia.     

Sensory stores and high-speed scanning

A model of scanning based on separate sensory and short-term stores was suggested and tested. The experiment used a probe recognition method, with set size varied from 1 to 8 and a fast presentation rate. A masking procedure was used to vary the number of items available in a possible sensory store. Although conditions were such as to maximize the chances of detecting an effect, none was found: the possible size of the sensory store had no effect on reaction time whatsoever. Other aspects of the data lent little support to a serial exhaustive scanning model, but a previously proposed parallel processing model fared better. Finally, not only was the function for positive probes steeper than that for negative probes but also there was a crossover effect as well. This crossover is not without precedent and may indicate the need for consideration of both accuracy and latency in high-speed scanning studies.     

Humor in Teams: Multilevel Relationships Between Humor Climate,Inclusion, Trust,and Citizenship Behaviors

Purpose

This study examines the cross-level influence of positive and offensive leader humor climates on employee inclusion and citizenship behaviors, and the moderating effect of trust in such relationships.

Design/Methodology/Approach

We collected data from a sample of 225 respondents nested within 23 teams from a Canadian financial organization. A multilevel confirmatory analysis was used to provide evidence that variables of this study are distinct and a HLM analysis to test the hypotheses.

Findings

We find that employees’ perception of inclusion is influenced much more by an offensive humor climate than by a positive one. The results also suggest that the perception of inclusion plays a significant intermediary role in the influence of humor climates on citizenship behavior. Finally, trust in leaders acts as an important contingent condition in the effectiveness of a humor climate.

Implications

Use of humor does not always pay. Offensive humor by supervisor is a risky strategy that may undermine the beneficial effects of positive humor climate, increase employee exclusion and weaker individual performance.

Originality/Value

Our study shows the utility of using micro- and macro-approaches, and more specifically, the relevance of adopting an integrative multilevel view of the effect of a humor environment in predicting individual inclusion and citizenship behaviors.
