The relationship among attributions,divergent thinking,and retention of nonsense syllables and nonrelated words

Students' employment of meaning through cognitive strategies in a retention task was explored in terms of attributional assignment and/or divergent thinking. Students were randomly assigned to either a list of nonsense syllables or nonrelated words. Attributional assignment was measured by Lefcourt's Multidimensional-Multiattributional Causality Scales (MMCS – IV); divergent thinking was measured by Guilford's tests of Fluency, Flexibility, and Originality. A questionnaire assessing students' beliefs regarding success and failure was also administered. No relationship was found among attributional assignment as measured by the MMCS-IV, divergent thinking, and retention. Strategy use was not related to retention. Students' attributional beliefs regarding failure were predictive of retention for the nonsense syllables. Discussion suggests the need to distinguish between tactic and strategy through analysis of metacognitive processes. Interpretation of the results may indicate that the divergent-thinking measures were not sensitive enough and/or the retention task did not require these divergent-thinking skills.     

Delayed Onset Muscle Soreness After Inspiratory Threshold Loading in Healthy Adults

Purpose: Skeletal muscle damage occurs following high-intensity or unaccustomed exercise; however, it is difficult to monitor damage to the respiratory muscles, particularly in humans. The aim of this study was to use clinical measures to investigate the presence of skeletal muscle damage in the inspiratory muscles. Methods: Ten healthy subjects underwent 60 minutes of voluntary inspiratory threshold loading (ITL) at 70% of maximal inspiratory pressure. Maximal inspiratory and expiratory mouth pressures, delayed onset muscle soreness on a visual analogue scale and plasma creatine kinase were measured prior to ITL, and at repeated time points after ITL (4, 24 and 48 hours post-ITL). Results: Delayed onset muscle soreness was present in all subjects 24 hours following ITL (intensity = 22 ± 6 mm; significantly higher than baseline p = 0.02). Muscle soreness was reported primarily in the anterior neck region, and was correlated to the amount of work done by the inspiratory muscles during ITL (r = 0.72, p = 0.02). However, no significant change was observed in maximal inspiratory or expiratory pressures or creatine kinase. Conclusions: These findings suggest that an intense bout of ITL results in muscle soreness primarily in the accessory muscles of inspiration, however, may be insufficient to cause significant muscle damage in healthy adults.Key Words: delayed onset muscle soreness, respiratory muscles, skeletal muscle damage
