The free weight bench press test is one of the most convenient tests used to evaluate muscular fitness and the effectiveness of resistance training programs for a variety of sports. However, its use and interpretation as an evaluative measurement for health-related physical fitness tests are limited because there are few published reference values derived for the general population. Therefore, the aims of the present study were to generate normative values for free weight bench press 1 repetition maximal (RM) and 4 sets of 65% of 1RM training volume (total repetitions × resistance) for 20- to 29-year-olds for men and women.

The purpose of this study was to compare the effects of three different workload protocols on exercise volume completed during multiple sets of exhaustive anaerobic running on a treadmill. The longer times per set and greater volume achieved during the descending speed (DS) protocol, in comparison to the descending grade (DG) and constant set (CS) protocols, suggests the potential for a greater training effect. Total exercise volume achieved during the four sets of the DS protocol was significantly higher than both the CS and DG protocols. Differences in cadence values among the protocols could help explain differences in performance implicating muscle fiber type recruitment and fatigue.

The the human body undergoes a suite of physiological changes during stress,
including changes in blood flow. These changes in blood flow may be detectable
using new thermal imaging techniques. The present study was designed to
determine the time-course and topography of temperature changes in the face during
the experience of a psychosocial stressor. Our results suggest that thermography
may offer a non-invasive method for assessing arousal. This study is an important
first step in assessing the sensitivity of this technology to various affective states.
Additional research measuring different emotions is needed to determine the
applicability of this technology in the public sector.
Responses to infant facial cues in parents and non-parents

Infant facial features elicit perceptions of cuteness and capture attention in adults. It is believed that this attunement to infant cues may enhance motivation to engage in caretaking behavior. A number of recent studies have investigated liking and wanting responses to infant faces using perceptual ratings of cuteness as a measure of liking and an effort-based key-press task as a behavioral measure of wanting. It has been speculated that these two measures are likely to be important components in parental behavior, but this link has not yet been explicitly tested. To address this issue, we measured liking and wanting responses to infant facial cuteness in parents and non-parents.

There is more that differentiates students who succeed in school from those who do not, and focusing on differences in IQ will yield little to no knowledge about why some succeed and others fall behind. Research on growth and fixed mindset has shown that the way students perceive their intelligence, skills, and/or abilities has the potential to impact their academic performance (Dweck, 2006) . This study investigates the immediate impact of being presented with fixed or growth mindset information and uses time spent on problem questions as a measure of mindset.

To investigate the role of hormones in female intrasexual competition, we carried out a longitudinal study of changes in intrasexual competitiveness (Study 1) and assessed intrasexual competition in women using various forms of hormonal contraceptives (Study 2). Study 1: Multilevel modeling of the data revealed a significant, positive within-subject effect of testosterone on intrasexual competition, indicating that women reported greater intrasexual competitiveness when testosterone was high. Study 2: No significant differences were observed for reported intrasexual competition among women using combined oral contraceptives versus women using progesterone-only contraceptives.

Affirmative action policies have been put into place to help women make the steps towards equality and hopefully amend prejudiced attitudes.The current study focuses on types of sexism and their relationship towards affirmative action support. It is hypothesized that higher scores on hostile and benevolent sexism will be associated with decreased support for affirmative action directed towards women. Community members in Northern California (N = 110) were measured. Measures include that of hostile, benevolent, and ambivalent sexism. Results indicate that only hostile sexism is potentially a key factor in determining whether individuals oppose affirmative action directed towards women.
Lesson Study Across Waters

Humboldt State University (HSU) students participated in the first part of an international lesson study by developing and implementing curriculum about climate change. Together with Swiss students from Haute Ecole Pédagogique du Canton de Vaud (HEP ), ideas of pedagogy were shared while developing, deploying, and revising an engaging lesson plan. With the goal to better understand lesson development and successful teaching strategies in the classroom, the students are to repeat this process at least three more times in Switzerland.

The goal of our research is to analyze the effect of copper toxicity in anti-fouling paint on invasive bryozoan specie. The goal of this project is to determine the ideal concentration of copper in anti-fouling paint to prevent the ability of these invasive specie to attach themselves to ship hulls and be transported around the oceans.
Assessing The Effectiveness of Latinx Center for Academic Excellence & Cultural Space Model Mentorship

We will be assessing the newly implemented programming model used by the LCAE in order to understand where improvements are needed and where we can identify strengths to establish best practices at the center. We will also be looking at how many people use the center and how we can focus outreach efforts in the future. This assessment is being done for internal programming purposes and to support HSU in its larger mission to improve outcomes for students of color, particularly Latinx students at HSU.
