Causal attributions of physical education majors and mentally retarded adults

This exploratory study examined the causal attributions and expectancies of 51 physical education majors and 25 mentally retarded adults. The majors completed a written questionnaire concerning their causal attributions and expectancies for motor performance of the adults. The adults responded through an interview procedure regarding causal attributions and expectancies for their own motor performance. Analysis did not support the hypothesis that people make stable attributions about the performance of mentally retarded populations and subsequently maintain low expectancies. Previous experiences of failure did not diminish the expectancies of the adults for their own future success.

Temporal summation of 500-Hz tones and octave-band noise bursts in infants and adults

A visually reinforced operant procedure was employed to obtain 2-point threshold-duration functions in 7-month-old infants and adults in two experimental paradigms. In Experiment 1, thresholds were determined for 10- and 100-msec, 500-Hz tones and octave-band noise bursts presented in quiet and noise backgrounds. Threshold-duration functions were significantly steeper for infants than for adults under all experimental conditions, and did not differ in slope as a result of differences in either stimulus bandwidth or masking noise. In Experiment 2, thresholds for trains of brief 500-Hz tone pulses were examined in infant and adult subjects. Infant functions were adult-like for integration of multiple-pulse stimuli, suggesting that the traditional, long-term process of temporal summation is mature by 7 months of age. Differences between the present results and those previously obtained for 4-kHz stimuli appear to be consistent with the view that different mechanisms are involved in the detection of low- and high-frequency signals.     

Testing a SEM Model of Two Religious Concepts and Experiential Spirituality

Guided by Atchley’s Continuity Theory of the Spiritual Self as presented in Aging, spirituality, and religion, Fortress Press, Minneapolis, MN (1995), this study tested the validity of two dimensions of religiosity and one dimension of spirituality. It then examined the extent to which each dimension of religiosity influenced having spiritual experiences for 221 chronically ill older adults. Mean age of the sample was 80 years. Structural equation modeling was used to test a conceptual model. Substantive findings were that private religiosity (prayer and coping), but not public religiosity (participation and other church involvement) may influence reporting spiritual experiences by the older adults in the study. Findings revealed a good model fit to the data and strong factor loadings revealed sound construct validity for the latent variables (i.e., public and private religiosities, and experiential spirituality) in the model.     

Effect of masker level on infants’ detection of tones in noise

In adult listeners, the signal-to-noise ratio at masked threshold remains constant with increases in masker level over a wide range of stimulus conditions. This relationship was examined in 7-month-old infants by obtaining masked thresholds for .5- and 4-kHz tones presented in four levels of continuous masking noise. Adults were also tested for comparison. Masker spectrum levels ranged from 5 to 35 dB/Hz for .5-kHz tones, and from ?5 to 25 dB/Hz for 4-kHz stimuli. Thresholds were determined for stimuli of both 10 and 100 msec in duration. The results indicated that infants’ performance was more adultlike for 4-kHz stimuli. Although mean thresholds for both 10- and 100-msec, 4-kHz tones were approximately 7 dB higher in infants than in adults, E/N₀ at threshold remained essentially constant over the 30-dB range of maskers employed. By contrast, infants’ thresholds for .5-kHz tones were exceptionally high at lower levels of the masker. Threshold E/N0 decreased significantly as masker level increased from 5 to 35 dB/Hz, and this decrease was significantly greater for 10- than for 100-msec stimuli. Temporal summation of .5-kHz tones, measured as the difference between thresholds obtained at the two signal durations, was greater for infants than for adults at low levels of the masker. However, because infants’ thresholds improved more rapidly with level for 10- than for 100-msec tones, age differences in temporal summation were no longer significant when masker spectrum level was 35 dB/Hz. These results suggest that the relationship between signal-to-noise ratio at masked threshold and level of the masker is dependent on both signal frequency and duration during infancy.     

Communication technology: Pros and cons of constant connection to work

We examined the relationship between employees' attitudes related to communication technology (CT) flexibility, communication technology (CT) use, work-to-life conflict and work satisfaction. Based on data obtained from 193 employees, CT flexibility predicted more CT use. Further, CT use was associated not only with increased work satisfaction, but also with higher levels of work-to-life conflict. Finally, work-to-life conflict negatively predicted work satisfaction. Our findings point toward various trade-offs associated with CT use.     

Relations between stress and work outcomes: The role of felt challenge, job control, and psychological strain

Recent research on reported work stress indicates stress may not always be deleterious for an individual or organization. Research in this area, however, has not yet examined a variety of work outcomes, the mechanism by which stress leads to such outcomes, and the moderators of this effect. The present study hypothesized that two types of reported stress (challenge- and hindrance-related) have a divergent relationship with work outcomes (relating to desirable and undesirable outcomes, respectively) and a similar (positive) relationship with psychological strain. We also hypothesize felt challenge as a mechanism through which challenge stress relates to desirable outcomes and job control as a moderator of the effect. Results from a heterogeneous sample of university staff employees (N=461) supported many of the hypotheses. The two types of stress differentially related to work outcomes yet both positively related to psychological strain. In addition, felt challenge mediated the relationship between challenge-related stress and work outcomes, yet the effect of challenge-related stress did not depend on job control.
