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.

Main Effects

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 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.

The Relationship

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.

This study examined simultaneously the effects of distance of projection (4-, 6-, and 8-horizontal ft.) and object size (6-, 8.5-in., and 10-in. diameter balls) on object reception by children in the first grade. 6 boys and 6 girls were randomly assigned to each of the 3 distances (36 subjects total). Each subject was administered 36 trials, 12 attempted catches with each ball size at their assigned distance. All balls were projected by a device designed to control accuracy as well as the angle of projection for projections to each distance. Each attempted catch was evaluated by a 5-point scale ( r = .96). Trials, sex, distance of projection, ball size, and related interactions were examined using a conventional analysis of variance. Ball size was the only significant main effect, but the interaction between ball size and sex was also significant. Post hoc analysis indicated that the 10-in. ball gave significantly more catching success than the 8.5- or the 6-in. ball. Although more success in catching was achieved with the larger ball sizes, no difference in catching was attributable to the varying distances. The sequences for catching success according to ball size at each distance were not significantly different.

Background: Supplementing β-alanine (BA) improves exercise performance in efforts that are highly dependent on anaerobic glycolysis. As it has not yet been established whether it relates to climbing, the current study aimed to investigate the effects of BA on climbing-specific performance. Methods: Fifteen elite climbers performed intermittent high-force high-velocity campus board exercise, and two bouldering traverses, hard and easy. They ingested 4.0 g·d−1 BA or placebo for four weeks in a double-blind, pre/post experimental design. Results: In the campus board trial, ANOVA revealed a tendency toward significance (p = 0.066). Post hoc analysis revealed that there was a significant (p = 0.002) and “large” (d = 1.55) increase in the total number of “slaps” in the BA group. No significant supplementation × group interaction was found in “hard” traverse and a significant interaction for mean changes in number of moves (p = 0.025) and in time to failure (p = 0.044) on an “easy” traverse. Post hoc analysis revealed that only the BA group significantly improved from baseline in number of moves (+9.5) and time to failure (+32 s). Effect sizes were d = 1.73 and d = 1.44, respectively. Conclusions: Four weeks of BA supplementation can improve performance during continuous climbing lasting about 1 min and repeated bouts of upper body campus-like movements. However, it failed to enhance climbing of a shorter duration.

The purpose of this study was to evaluate the validity and reliability of a tire pressure sensor (TPS) cycling power meter against a gold standard (SRM) during indoor cycling. Twelve recreationally active participants completed eight trials of 90 s of cycling at different pedaling and gearing combinations on an indoor hybrid roller. Power output (PO) was simultaneously calculated via TPS and SRM. The analysis compared the paired 1 s PO and 1 min average PO per trial between devices. Agreement was assessed by correlation, linear regression, inferential statistics, effect size, and Bland–Altman LoA. Reliability was assessed by ICC and CV comparison. TPS showed near-perfect correlation with SRM in 1 s (rs = 0.97, p < 0.001) and 1-min data (rs = 0.99, p < 0.001). Differences in paired 1 s data were statistically significant (p = 0.04), but of a trivial magnitude (d = 0.05). There was no significant main effect for device (F(1,9) = 0.05, p = 0.83, ηp2 = 0.97) in 1 min data and no statistical differences between devices by trial in post hoc analysis (p < 0.01–0.98; d < 0.01–0.93). Bias and LoA were −0.21 ± 16.77 W for the 1 min data. Mean TPS bias ranged from 3.37% to 7.81% of the measured SRM mean PO per trial. Linear regression SEE was 7.55 W for 1 min TPS prediction of SRM. ICC3,1 across trials was 0.96. No statistical difference (p = 0.09–0.11) in TPS CV (3.6–5.0%) and SRM CV (4.3–4.7%). The TPS is a valid and reliable power meter for estimating average indoor PO for time periods equal to or greater than 1 min and may have acceptable sensitivity to detect changes under less stringent criteria (±5%).

Main Effects

Intermodal and intramodal development in the auditory and visual sensory modes within a temporal dimension were investigated by testing 90 male and 90 female children who ranged in age from 5 to 13 yr. Auditory and visual stimuli were presented by electronic means in a same-different matching task. Four separate conditions were investigated: auditory-auditory, visual-visual, auditory-visual, and visual-auditory. An analysis of variance was conducted for two main effects, age and modality. Post hoc analysis was conducted on efficiency of sensory input mode. Modality functioning increased as a function of age until age 13 yr. Intramodal functioning was significantly more efficient than intermodal functioning. Efficiency of input mode varied as a function of age, though both auditory and visual mode efficiency followed similar developmental trends. Intermodal and intramodal development appeared to follow similar trends, with a child's inter- and intramodal functioning becoming more similar after 10 yr. Results are interpreted in light of Birch and L. Belmont's (1965a) sensory integration hypothesis and Goodnow's (1971) hypothesis of the development of rules for efficient modal functioning.

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.

Abstract Swine colostrum intake within the first 24 hours after birth plays a large role in determining survivability, feed efficiency, growth, and fertility. This study tested the effects of feeding three doses of a homogeneous colostrum sample on BW over 24h, RT, immunocrit, and growth through PND7. Three female piglets were selected from eight litters at birth (n = 24 piglets total; n = 3/liter), and bottle-fed 10% (COL10, n = 8), 15% (COL15, n = 8) or 20% (COL20, n = 8) BW colostrum over 24h. Piglet birth weights were similar between treatments (P = 0.838). Piglets were weighed, RT recorded and immunocrit measured at 24h postnatal, then returned to their litter of origin. BW was recorded daily through PND7. At 24h, COL20 had an ADG of 136.3g, COL15 86.3g, and COL10 8.8g, and an average RT of 39.30⁰C, 38.84⁰C and 38.81⁰C respectively. Immunocrit levels varied from 0.028, 0.024 and 0.017 at 24h. SAS MIXED procedure was used to perform statistical analysis. Post-hoc analysis was performed using Tukey’s test. Colostrum dose had an effect on 24h weight gain (P &lt; 0.001), RT (P = 0.007), immunocrit (P = 0.026), and growth through PND7 (P &lt; 0.05). Treatment, day and interaction were determined as main effects of BW and ADG through PND7. Post-hoc analysis showed COL20 had higher ADG (136.3±54.8g), RT (39.30±0.11°C) and immunocrit (0.028±0.010) at 24h than COL10 (ADG 8.8±24.9g, RT 38.81±0.26°C, immunocrit 0.017±0.004). COL15 ADG (86.3±85.2g) differed from COL10 (P &lt; 0.001), and RT (38.84±0.45) differed from COL20 (P = 0.017). There was no statistical difference in ADG between groups through PND7 (P = 0.874). One piglet within each treatment was crushed before PND7. This model permits controlled studies intended to understand the level of 24h colostrum intake on piglet growth and development using standardized, homogenous colostrum doses.
