Examining patterns suggestive of acquisition during functional analyses: A consecutive controlled series of 116 cases

The functional analysis approach described by Iwata et al. (1982/1994) has been used widely to determine the variables evoking and maintaining challenging behavior. However, one potential concern with conducting functional analyses is that repeated exposure to contingencies may induce a novel functional relation. To examine the likelihood of these potential iatrogenic effects, we evaluated social test conditions of the functional analysis for 116 participants and searched for patterns of responding indicative of acquisition. Patterns suggestive of acquisition occurred in 13.70% of tangible reinforcement conditions; however, the prevalence was only slightly lower in the attention condition (8.75%). Much lower prevalence was observed for the escape condition (2.13%). When grouped by quotient score, a pattern of acquisition was just as likely to be observed in the attention condition as in the tangible condition. Additionally, patterns indicative of acquisition were no more likely to be observed with participants who emitted automatically reinforced challenging behavior.     

Exploring the Accuracy and Simplicity of Idiographic Feeling-Performance Models

This study compared 3 types of idiosyncratic feeling-performance profiles: recall profiles, probabilistic-pIZOF profiles, and simplified “trigger” profiles. Ten tennis players created individualized (“initial recall”) profiles before monitoring their feelings and performances during matches (to generate “pIZOF profiles”). Participants identified 4 triggers items from their 12- or 13-item profiles that they felt were critical to their performance. Probabilistic-pIZOF profiles predicted performance correctly 64% of the time. Trigger profiles were 66% accurate (the top 3 were 70% accurate). Initial recall profiles were accurate 40% of the time. The study provides practical information about the utility of simplified profiles, and information about the accuracy of feeling-performance profile predictions. The results are also discussed within the framework of third-wave behavioral approaches such as mindfulness-acceptance-commitment therapies.     

Assessing the Effectiveness of Self-Talk Interventions on Endurance Performance

Self-talk in sport has been widely researched with somewhat conflicting results (Van Raalte et al., 1995 Van Raalte, J. L., Brewer, B. Brewer, Lewis, B. Lewis, Linder, D. Linder, Wildman, G. and Kozimor, J. 1995. Cork! The effects of positive and negative self-talk on dart throwing performance.. Journal of Sport Behavior, 18: 508–58.  [Google Scholar]; Perkos et al., 2002 Perkos, S., Theodorakis, Y. and Chroni, S. 2002. Enhancing performance and skill acquisition in novice basketball players with instructional self-talk.. The Sport Psychologist,, 16: 368–383. [Web of Science ®] , [Google Scholar]). The purpose of this study was to assess the effectiveness of three different self-talk interventions on endurance performance. Participants were nine cyclists who performed a 20-minute cycling ergometer workout two times per week for five weeks. At each workout participants were requested to cycle as far as possible. A multiple-baseline design was utilized, which after varying baseline lengths allowed for the implementation of one out of three self-talk interventions: self-regulated positive self-talk, assisted positive self-talk, and assisted negative self-talk. Results revealed a performance increase in all groups with the greatest increase being found in the assisted positive self-talk condition.     

Help or hinder? When recommendation signage expands consideration sets and heightens decision difficulty

This research examines whether recommendation signage helps or hinders the consumer when faced with choosing from large product assortments. In spite of frequent usage and retailer intuition suggesting that providing recommendation signs (e.g., “Best Seller,” “Award Winner”) should help consumers in the choice process, we propose that signs can hinder choice for consumers with more developed preferences by adding to the complexity and difficulty of the decision process. In three experiments using horizontally differentiated products in multiple categories, we provide evidence that recommendation signs create preference conflict for consumers with more developed preferences, leading these consumers to form larger consideration sets and ultimately experience more difficulty from the decision-making process. In addition, we show that these effects are mitigated for consumers with less developed preferences and when the choice is from a small assortment. The results suggest that recommendation signage may not be an effective tool for aiding choice from large assortments; instead signage can exacerbate the difficulties associated with having too many choices, with implications on purchase quantity.     

Faculty Perceptions about Tenure at Private Christian Liberal Arts Colleges

This study investigates faculty perceptions of tenure at 38 institutions of the Council for Christian Colleges and Universities (CCCU) with a sample of 988 faculty with tenure, 734 on a tenure track, 427 who are not on a tenure track, and 411 from institutions without tenure. Major findings that emerges are (1) more male have earned tenure; (2) the majority of tenures faculty agreed that the criteria for advancement and promotion are clear; (3) most disagree that tenure is an outmoded concept; (4) faculty with tenure are more likely to believe that tenure attracts the best minds; (5) CCCU faculty working toward tenure report lower levels of extensive stress than the national sample.     

Trajectories of relationship satisfaction: Independent contributions of capitalization and support perceptions

Associations among perceptions of partner responses to disclosures about capitalization and support experiences and relationship satisfaction were examined over 1 year in 268 individuals in romantic relationships. Multilevel modeling indicated that capitalization and support perceptions covaried over 1 year, but they independently predicted contemporaneous relationship satisfaction and appeared to be compensatory processes. However, with increasing relationship duration, support perceptions became more strongly associated with relationship satisfaction, whereas capitalization perceptions became less strongly associated with relationship satisfaction, suggesting that capitalization perceptions may play less of a buffering role with time. Results suggested that perceiving partners as interested and enthusiastic in the face of triumph, and as caring and supportive in the face of difficulties, serve important and independent relationship maintenance functions.     

Are boundary extension and representational momentum related?

Boundary extension (BE) is misremembering more of a particular scene than actually presented. Representational momentum (RM) is misremembering the final position of a moving object as further along its implied trajectory. There is a sense in which both BE and RM are predictions, and the current experiments explore the possibility that these are related phenomena. We showed participants single photographs to measure baseline BE, and then approach sequences and measured BE and RM. We found significant BE and RM, and a significant interaction between baseline BE and BE following an approach sequence, but no interaction with RM. The initial evidence suggests that BE and RM are separate processes, and that BE (the establishing of spatial layout) occurs before RM (the continuation of movement) within a scene.
