A comparison of ultra-endurance cyclists in a qualifying ultra-cycling race for Paris-Brest-Paris and Race Across America-Swiss cycling marathon

Ultra-endurance events test the adaptation of human physiology to extreme physical and mental demands, high levels of training, motivation, and physical conditioning among participants. To understand basic differences among participants according to the severity of the race, participants in qualifying events for two ultra-endurance cycling races, differing in length and intensity, were compared on measures of anthropometry, training, and support. One race was four times longer, required supporting teams, and racers typically had little sleep, which should lead to the qualifiers being substantially more highly trained than those from the shorter race. The qualifiers in the longer race had greater intensity in training while the qualifiers in the shorter race relied more on training volume. Different strategies and types of training reflected the different demands of the races. Future studies should evaluate personality and motivational differences in ultra-endurance events and between these athletes and athletes in other sports.     

The measurement of executive function at age 5: psychometric properties and relationship to academic achievement

This study examined the psychometric properties and criterion validity of a newly developed battery of executive function (EF) tasks for use in early childhood. The battery was included in the Family Life Project (FLP), a prospective longitudinal study of families who were oversampled from low-income and African American families at the birth of a new child (N = 1,292). Ninety-nine percent (N = 1,036) of children who participated in the age 5 home visit completed 1 or more (M = 5.8, Mdn = 6) of the 6 EF tasks. Results indicated that tasks worked equally well for children residing in low-income and not low-income homes, that task scores were most informative about the ability level of children in the low-average range, that performance on EF tasks was best characterized by a single factor, and that individual differences on the EF battery were strongly related to a latent variable measuring overall academic achievement, as well as to individual standardized tests that measured phonological awareness, letter-word identification, and early math skills.

Attentional bias towards angry faces is moderated by the activation of a social processing mode in the general population

ABSTRACT

Dot-probe studies usually find an attentional bias towards threatening stimuli only in anxious participants, but not in non-anxious participants. In the present study, we conducted two experiments to investigate whether attentional bias towards angry faces in unselected samples is moderated by the extent to which the current task requires social processing. In Experiment 1, participants performed a dot-probe task involving classification of either socially meaningful targets (schematic faces) or meaningless targets (scrambled schematic faces). Targets were preceded by two photographic face cues, one angry and one neutral. Angry face cues only produced significant cueing scores (i.e. faster target responses if the target replaced the angry face compared to the neutral face) with socially meaningful targets, not with meaningless targets. In Experiment 2, participants classified only meaningful targets, which were either socially meaningful (schematic faces) or not (schematic houses). Again, mean cueing scores were significantly moderated by the social character of the targets. However, cueing scores in this experiment were non-significant in the social target condition and significantly negative in the non-social target condition. These results suggest that attentional bias towards angry faces in the dot-probe task is moderated by the activation of a social processing mode in unselected samples.     

The consequences of pain: The social and physical pain overlap on psychological responses

Current theories suggest that social and physical pain overlap in their neurological and physiological outcomes. We investigated how social and physical pain overlap in their psychological responses by testing the hypothesis that both social and physical pain would thwart satisfaction on four human needs, worsen mood, and increase desire to aggress. In Experiment 1, recalling an experience of social or physical pain produced overlapping effects in the form of thwarted self‐esteem and control needs and increased negative affect and desire to aggress. In Experiment 2, we induced social (Cyberball ostracism) or physical pain (cold pressor) within the laboratory session, and found that both pain types produced feelings of being ignored and excluded, and thwarted belonging, self‐esteem, control, and meaningful existence. Our results provide further support to pain overlap theories and indicate that social and physical pain cause common psychological consequences, resulting in new ways to understand and manage pain.

Contributions of modern measurement theory to measuring executive function in early childhood: An empirical demonstration

This study demonstrates the merits of evaluating a newly developed battery of executive function tasks, designed for use in early childhood, from the perspective of item response theory (IRT). The battery was included in the 48-month assessment of the Family Life Project, a prospective longitudinal study of 1292 children oversampled from low-income and African American families. IRT models were applied to a select set of tasks to demonstrate empirically (a) a principled method for item evaluation, including the utility of item characteristic curves; (b) how to explicitly test whether the measurement properties of executive function tasks are invariant across mutually exclusive subgroups of youths; (c) how the precision of measurement of a given task can vary according to underlying child ability; and (d) the utility of using IRT-based versus percentage correct scores. Results are discussed with respect to the importance of developing psychometrically sound and scalable instruments that facilitate the measurement of interindividual differences in intraindividual change of executive function across the early childhood period.     

Intra- and inter-judge reliabilities in measuring the skin-fold thicknesses of ultra runners under field conditions

Inter- and intra-judge reliabilities of skinfold measures were investigated in a sample of 27 men and 11 women ultramarathon runners. Two physicians had agreement higher than 90% in field measurements before an ultramarathon race.     

Perceived facial expressions of emotion as motivational incentives: evidence from a differential implicit learning paradigm

Participants (N = 216) were administered a differential implicit learning task during which they were trained and tested on 3 maximally distinct 2nd-order visuomotor sequences, with sequence color serving as discriminative stimulus. During training, 1 sequence each was followed by an emotional face, a neutral face, and no face, using backward masking. Emotion (joy, surprise, anger), face gender, and exposure duration (12 ms, 209 ms) were varied between participants; implicit motives were assessed with a picture-story exercise. For power-motivated individuals, low-dominance facial expressions enhanced and high-dominance expressions impaired learning. For affiliation-motivated individuals, learning was impaired in the context of hostile faces. These findings did not depend on explicit learning of fixed sequences or on awareness of sequence-face contingencies.     

Predicting Quality of Life After Lumbar Spondylodesis

Quality of life after spondylodesis was predicted by pretreatment psychological variables and findings in a standardized physical examination. Four quality-of-life criteria were used: functional capacity, vocational rehabilitation, satisfaction with the outcome of the operation, and pain intensity recorded in a pain diary. Those of six presurgery variables that proved to be associated with the outcome 9 months postsurgery, by means of a multiple stepwise regression procedure, were selected for discriminant analyses. The sample consisted of 50 consecutive patients who underwent either ventral (n = 10) or posterolateral (n = 40) spondylodesis with or without posterior instrumentation. Their average age was 44.9 years (SD = 12.9) with an average duration of pain of 8.6 years (SD = 8.8). Nearly half of the patients had had previous spine surgery. Follow-up data indicate that about half of the patients show a beneficial outcome in terms of quality-of-life measures. Discriminant analyses suggest that poor presurgical functional capacity and an unclear finding in the physical examination before surgery contribute to our knowledge about patients who are likely to show continuous pain and poor functional capacity after surgery.
