To further improve treatments, we need to better understand potential common treatment mechanisms, such as decentering, or the ability to observe thoughts and feelings as objective events in the mind rather than personally identifying with them (Safran & Segal, 1990). Therefore, this study examined whether 12 sessions of Cognitive Behavioral Group Therapy (CBGT) for 63 clients (57.6% female, 50.8% White) diagnosed with social anxiety disorder led to increases in decentering and whether increased decentering was associated with improved outcome. Furthermore, this study examined whether decentering was associated with outcome over and above a competing mechanism—cognitive reappraisal. Overall, results indicated that CBGT in this study led to similar outcomes compared to previous studies and decentering increased over CBGT (d’s from 0.81 to 2.23). Change in decentering predicted improvement on most, but not all, measures of outcome and those who no longer met criteria for social anxiety disorder at posttreatment had significantly greater change in decentering across therapy and significantly higher decentering scores at post-treatment compared to those who retained a social anxiety disorder diagnosis at posttreatment. Finally, changes in decentering predicted outcome over and above changes in reappraisal on all outcome measures. These results largely support the role of decentering in CBGT for social anxiety; however, the implications of the inconsistencies in results based on which outcome measure was used are discussed. 相似文献

The inability to maintain signal detection performance with time on task, or vigilance decrement, is widely studied in people because of its profound implications on attention-demanding tasks over sustained periods of time (e.g., air-traffic control). According to the resource depletion (overload) theory, a faster decrement is expected in tasks that are cognitively demanding or overstimulating, while the underload theory predicts steeper decrements in tasks that provide too little cognitive load, or understimulation. Using Trite planiceps, a jumping spider which is an active visual hunter, we investigated vigilance decrement to repetitive visual stimuli. Spiders were tethered in front of two stimulus presentation monitors and were given a polystyrene ball to hold. Movement of this ball indicates an attempt to turn towards a visual stimulus presented to a pair of laterally facing (anterior lateral) eyes for closer investigation with high acuity forward-facing (anterior median) eyes. Vigilance decrement is easily measured, as moving visual stimuli trigger clear optokinetic responses. We manipulated task difficulty by varying the contrast of the stimulus and the degree of ‘noise’ displayed on the screen over which the stimulus moved, thus affecting the signal:noise ratio. Additionally, we manipulated motivation by paired testing of hungry and sated spiders. All factors affected the vigilance decrement, but the key variable affecting decrement was stimulus contrast. Spiders exhibited a steeper decrement in the harder tasks, aligning with the resource depletion theory. 相似文献

Decisions to use selection devices or training are typically based on subject matter expert (SME) judgments concerning the trainability of job components, including tasks and knowledge, skills, abilities, and other characteristics (KSAOs). The studies reported here examined the validity of SME trainability judgments from two perspectives. We found that (1) different SME groups' judgments related differently to actual learning changes in KSAOs covered in a training program and (2) sources of variability thought to be unrelated to the job influenced trainability ratings. Implications for the selection of SMEs in job analysis applications intended to determine the trainability of various job components are outlined. 相似文献
