Purpose Previous work has established that advanced bolus location at swallow onset (BLSO) alone is not correlated with an increased swallowing safety risk in healthy seniors. The primary goal of this retrospective study was to examine whether healthy seniors systematically alter their laryngeal vestibule closure reaction time (LVCrt) to maintain a safe swallow in the context of advanced BLSO. The secondary goal was to determine if longer LVCrt distinguished Penetration–Aspiration Scale (PAS; Rosenbek, Robbins, Roecker, Coyle, & Wood, 1996) scores of 1 versus 2. Method Videofluoroscopy studies from 43 healthy seniors (21 men, 22 women; M age = 76.7 years, SD = 7.2) were analyzed. LVCrt was calculated for 3 × 5 ml and 3 × 20 ml thin liquid barium boluses per participant. PAS and BLSO (Modified Barium Swallow Impairment Profile Component 6) were scored for all swallows. Reliability (intraclass correlation coefficient > .75) was established on all measures. A linear mixed-effects regression was run to examine the effect of PAS and BLSO on LVCrt while controlling for bolus volume and repeated swallow trial. Results There was a main effect of BLSO ( F = 4.6, p = .004) and PAS ( F = 29.3, p < .001) on LVCrt. Post hoc pairwise comparisons revealed that LVCrt was significantly faster in BLSO scores of 3 (pyriforms) compared to scores of both 0 (posterior angle of the ramus) and 1 (valleculae). Significantly prolonged LVCrt was observed in PAS scores of 2 in comparison to 1. No significant main effects of bolus volume or trial, or interactions, were observed. Conclusions Our findings suggest that healthy seniors compensate for advanced BLSO by increasing their LVCrt. Furthermore, faster LVCrt was shown to distinguish PAS scores of 1 versus 2. Additional work should explore the relationship between LVCrt, BLSO, and PAS scores in dysphagic populations, specifically those with known sensory impairments.

320 Croatian female students ( M = 20.4 yr.) were recruited to examine the validity and reliability of figural scales using different numbers of stimuli (3, 5, 7, and 9) and different serial presentation (serial and nonserial order). A two-way analysis of variance (4 numbers × 2 orders of stimuli) was performed on ratings of current self-size and ideal size as dependent variables. Analysis indicated a significant main effect of number of stimuli. This, together with post hoc tests indicated that ratings were significantly different for a scale of three figures from scales of more figures, which in turn did not differ among themselves. Main effects of order of stimuli, as well as the interaction, were not significant. The results support the hypothesis that the optimal number of figures on a scale is seven plus (or minus) two.

The effects of both symmetry (perceptual factor) and familiarity (cognitive factor) on facial attractiveness were investigated. From the photographs of original slightly asymmetric faces, symmetric left-left (LL) and right-right (RR) versions were generated. Familiarity was induced in the learning block using the repetitive presentation of original faces. In the test block participants rated the attractiveness of original, previously seen (familiar) faces, original, not previously seen faces, and both LL and RR versions of all faces. The analysis of variance showed main effects of symmetry. Post hoc tests revealed that asymmetric original faces were rated as more attractive than both LL and RR symmetric versions. Familiarity doesn?t have a significant main effect, but the symmetry-familiarity interaction was obtained. Additional post hoc tests indicated that facial attractiveness is positively associated with natural slight asymmetry rather than with perfect symmetry. Also, unfamiliar LL symmetric versions were rated as more attractive than familiar LL versions, whereas familiar RR versions were rated as more attractive than RR unfamiliar faces. These results suggested that symmetry (perceptual factor) and familiarity (cognitive or memorial factor) play differential roles in facial attractiveness, and indicate a relatively stronger effect of the perceptual compared to the cognitive factor.

The purpose of this study was to examine the positive effect of self-monitoring among emotional display rules (fostering positive emotion(FPE) & suppressing negative emotion(SNE)) and consequential work attitude (job burnout & work engagement). A sample of 191 hotel employees were participated in this study and data were analyzed by SPSS. The results are as follows. First, the main effect of FPE on work engagement was supported, but the main effect of SNE on job burnout was not. Second, the main effects of self-monitoring on engagement and burnout were supported. Third, the moderation effects of self-monitoring which buffer the relationship of SNE on burnout and which facilitate the relationship FPE on engagement were significant. Finally, the implications and limitations were discussed.

The purpose of the present investigation was to determine the relationship between competitive trait anxiety (CTA), state anxiety, and golf performance in a field setting. Ten low, moderate, and high CTA collegiate golfers (N = 30) performed in a practice round on Day 1 and Day 2 of a competitive tournament. State anxiety results indicated a significant CTA main effect with low CTA subjects displaying lower state anxiety than moderate or high CTA subjects. The competition main effect was also significant, with post hoc tests indicating higher levels of state anxiety during Day 1 and Day 2 than during the practice round. Performance results produced a significant CTA main effect with low CTA subjects displaying higher levels of performance than moderate or high CTA subjects. Correlations between SCAT and state anxiety indicated that SCAT was a good predictor of precompetitive state anxiety. The direction of state anxiety and performance CTA main effects provide support for Oxendine's (1970) contentions that sports requiring fine muscle coordination and precision (e.g., golf) are performed best at low levels of anxiety. Future directions for research are offered.

Main Effects

A single-solution anagram task was administered to high and low test-anxious 32 male and 32 female undergraduates under conditions of high and low external distraction. No significant main effects were found linking solution times to either test-anxiety level or the presence or absence of distracting stimuli. Following a planned post hoc analysis which assigned the anagrams into ‘hard’ or ‘easy’ categories, a significant main effect for level of test anxiety was found for the ‘hard’ anagrams, indicating that test anxiety debilitates performance only when the criterion task is especially difficult. Difficulty of anagrams also significantly interacted with subjects' sex, test anxiety, and distraction. The results are discussed in terms of the hypotheses that distracting stimuli may produce increases in arousal during difficult tasks and that these increments may either compromise or improve performance, depending upon the level of test anxiety which is viewed as a determinant of the initial arousal level of the subject.

The Relationship

In a study of the relationship between name frequency and perceived social class, 116 college students rated the perceived social class of a list of either 60 male names or 60 female names. Each list consisted of equal numbers of common, less common, dated, or rare names. An analysis of variance indicated significant main effects of sex of name and frequency of name as well as a significant interaction between those two variables. The respondents rated the men's names as higher in social class than the women's names. Post hoc comparisons indicated that rare names of either sex were rated as lower in class status than were common, less common, or dated names. While dated women's names were rated lower than were common and less common women's names, dated men's names were not adversely affected in a comparison with common or less common men's names.

The Relationship

This Short Methodological Report builds on research about moderation practices by focusing on a marginal effects approach to interpreting how a main effect is informed by the presence of a moderating variable. Following a content analysis of published studies and a survey of management researchers, our findings suggest there is a great deal of confusion about the ways in which to interpret how a main effect may fluctuate owing to a moderating variable. We therefore provide explicit instructions on how to implement and interpret a marginal effects approach that depicts the nature of a main effect in the presence of a moderator. We use different scenarios and examples to illustrate how researchers can employ the marginal effects technique, which provides an indication of the relationship between the independent and dependent variables over different values of the moderator. We argue and demonstrate that the marginal effects approach helps resolve conflicting findings that may arise from using other prevailing techniques to interpret both main effects and moderation.

This study extends previous research on the expectancy construct of the expectancy-value theory of motivation developed by Pintrich. In addition to value and expectancy for success, it is proposed that people take into account how much effort is required to complete a task. A 2 × 2 × 2 analysis of variance design was used to investigate the relationship of Difficulty, Consequence, and Required Effort on the willingness of participants to complete a task. The dependent variable was the score obtained from completing statistical problems that varied in difficulty and effort required to complete. 128 students at a public university were participants. Analysis showed significant main effects and an interaction for difficulty and required effort, but no main effect for consequence. Results are discussed in terms of creating optimal motivation for classroom tasks and for both classroom and standardized examinations. Implications for students in subject pools are also discussed.

Background: HIV (Human immunodeficiency Virus), AIDS and cancer are feared terminal diseases. HIV sufferers are known to be stigmatized. The stigma surrounding cancer, unfortunately, is hardly the focus of psychological investigations, and hence this provoked the need to compare the stigma suffered by both groups, and how these have impacted on the psychological functioning of the disease sufferer. Objectives: The study had two main objectives, firstly, to explore whether HIV patients suffer more stigma than cancer patients or not, and secondly, to understand the most common type of stigma and if stigma is associated with psychopathology. Psychopathology is measured with GHQ–28 which evaluates somatic complaints, anxiety, depression and social dysfunction.Method: The study was a survey, and descriptive in nature, and anchored on two hypotheses: Firstly, that HIV patients will experience more stigmas than cancer patients and consequently report more psychological dysfunctions. Secondly that there will be a significant difference between types of stigma and the symptoms reported about them. Data were collected from a conveniently sampled group of 50 HIV positive patients and another 50 patients diagnosed with cancer, in two clinics and a hospital around the Gauteng Province. The majority of the participants were females, numbering 62 (62, 0%), whilst 38 (38.0%) were males. The age of the respondents ranged from 20–73 years with a mean age of 44.4 years (s.d. = 11.6).Results: Results revealed a significant main effect for enacted stigma F = (1.98), = 17.629, p < .001 and anxiety F = (1.98) = 5.750, p < .001. A post hoc Bonferroni also showed that HIV patients had a higher mean score of enacted stigma (X-bar = 4.22) than cancer patients (X-bar = 1.28) and also HIV patients reported more anxiety (X-bar = 8.81) than cancer patients (X-bar = 6.42). Enacted stigma significantly influenced the GHQ Total (F = (98) = 1.700, p < .05); anxiety (F = (97) = 2.578, p < .004); and depression (F = (97) = 3.390 p < .001). The perceived community stigma had one main effect for depression (F = (1.98) = 1.452, p < .05). There were no significant main effects for internally felt stigma and psychological dysfunctions. Both hypotheses were partially supported.Conclusion: Recommendations included tailoring interventions to meet the cultural needs of patients. Other recommendations were made in accordance with the findings of the study.

AbstractTo investigate the effects of increasing axial load on cervical motor control. Surrogates of cervical motor control were active cervical range of motion (C-ROM) and joint position error (JPE) assessed in flexion, extension, lateroflexion and rotation directions in 49 healthy young men (mean age: 20.2 years). All measurements were executed with 0-, 1-, 2-, and 3-kg axial loads. Linear mixed models were used to assess the effects of axial loading and cervical movement-direction on C-ROM and JPE. Post-hoc analysis was performed to compare load levels. Axial loading (p = 0.045) and movement direction (p < 0.001) showed significant main effects on C-ROM as well as an interaction (p < 0.001). C-ROM significantly changed with 3-kg axial load by decreaseing extension (− 13.6%) and increasing lateroflexion (+ 9.9%). No significant main effect was observed of axial loading on JPE (p = 0.139). Cervical motor control is influenced by axial loading, which results in decreased C-ROM in extension and increased C-ROM lateroflexion direction.
