An illusion of unfairness in random coin flips.

Random procedures, such as coin flips, are used to settle disputes and allocate resources in a fair manner. Even though the outcome is random, we hypothesized that people would be sensitive to features of the process that make it seem unfair, that is, who gets to call heads or tails and flip the coin. In 11 studies ( = 5,925) participants competed against another participant for a positive or negative outcome, determined by a physical or virtual coin flip.

Mapping axillary sensory cutaneous nerves for enhanced analgesic approaches in axillary surgery: a cadaveric study.

Background: Innervation of the breast includes branches of thoracic intercostal nerves, the superficial cervical plexus, the brachial plexus, and the intercostobrachial nerve (ICBN). Commonly used blocks for breast surgery provide incomplete analgesia of the axillary region. This cadaveric study aims to identify and map the axillary sensory cutaneous nerves.

Evaluation of a novel nerve ablation technique to relieve lower back pain: a cadaveric feasibility pilot study.

Introduction: Radiofrequency ablation is a treatment for facetogenic low back pain that targets medial branches of lumbar dorsal rami to denervate facet joints. Clinical outcomes vary; optimizing cannula placement to better capture the medial branch could improve clinical outcomes. A novel parasagittal technique was proposed from an anatomic model; this technique was proposed to optimize capture of the medial branch.

Gaze and hand behaviors during haptic abilities testing-An update to multimedia learning theory.

The Cognitive Theory of Multimedia Learning (CTML) suggests humans learn through visual and auditory sensory channels. Haptics represent a third channel within CTML and a missing component for experiential learning. The objective was to measure visual and haptic behaviors during spatial tasks.

Do our hands see what our eyes see? Investigating spatial and haptic abilities.

Spatial abilities (SAs) are cognitive resources used to mentally manipulate representations of objects to solve problems. Haptic abilities (HAs) represent tactile interactions with real-world objects transforming somatic information into mental representations. Both are proposed to be factors in anatomy education, yet relationships between SAs and HAs remain unknown.

Speak Up! Mistaken Beliefs About How Much to Talk in Conversations.

We hypothesized that people would exhibit a , the incorrect belief that they will be more likable if they speak less than half the time in a conversation with a stranger, as well as , the belief that their speaking time should depend on their goal (e.g., to be liked vs.

What is social psychology? The construal principle.

Standard definitions of social psychology, such as "the study of the way in which people's thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people" (Aronson et al., 2019, p. 3), fail to capture much of what social psychologists actually do and do not capture the basic theoretical foundations of the field.

Tips From the Top: Do the Best Performers Really Give the Best Advice?

Everyone knows that if you want to learn how to do something, you should get advice from people who do it well. But is everyone right? In a series of studies ( = 8,693), adult participants played a game after receiving performance advice from previous participants. Although advice from the best-performing advisors was no more beneficial than advice from other advisors, participants believed that it had been-and they believed this despite the fact that they were told nothing about their advisors' performance.

What makes thinking for pleasure pleasurable?

When left to their own devices, people could choose to enjoy their own thoughts. But recent work suggests they do not. When given the freedom, people do not spontaneously choose to think for pleasure, and when directed to do so, struggle to concentrate successfully.

Do conversations end when people want them to?

Do conversations end when people want them to? Surprisingly, behavioral science provides no answer to this fundamental question about the most ubiquitous of all human social activities. In two studies of 932 conversations, we asked conversants to report when they had wanted a conversation to end and to estimate when their partner (who was an intimate in Study 1 and a stranger in Study 2) had wanted it to end. Results showed that conversations almost never ended when both conversants wanted them to and rarely ended when even one conversant wanted them to and that the average discrepancy between desired and actual durations was roughly half the duration of the conversation.

Learning in Stereo: The Relationship Between Spatial Ability and 3D Digital Anatomy Models.

Three-dimensional (3D) digital anatomical models show potential to demonstrate complex anatomical relationships; however, the literature is inconsistent as to whether they are effective in improving the anatomy performance, particularly for students with low spatial visualization ability (Vz). This study investigated the educational effectiveness of a 3D stereoscopic model of the pelvis, and the relationship between learning with 3D models and Vz. It was hypothesized that participants learning with a 3D pelvis model would outperform participants learning with a two-dimensional (2D) visualization or cadaveric specimen on a spatial anatomy test, particularly when comparing those with low Vz.

"I'll try the veggie burger": Increasing purchases of sustainable foods with information about sustainability and taste.

Food production--especially raising animals for meat--has a massive negative impact on the environment and contributes to global warming. To address this, we investigated whether information about food sustainability would increase purchases of sustainable foods by patrons of university cafés. In Study 1, patrons were randomly assigned either to see a menu that had sustainability labels indicating the degree of environmental impact of each item, or to see a menu without labels.

Clinical Anatomy and Unexpected Careers: Is There Curriculum for That?

Reduction in faculty positions in higher education and increased graduate matriculation rates represent a higher education conundrum. Planned happenstance theory (PHT) is a career development model focusing on positive outcomes resulting from unpredictable precareer events. This mixed methods study explores how PHT applies to the career paths of a clinical anatomy (CA) postgraduate cohort.

Concussion-related deficits in the general population predict impairments in varsity footballers.

Objective: We investigated the long-term cognitive effects of concussion in 19,261 members of the general population and a cohort of varsity American football players with a history of frequent head impacts, using tests that are known to be sensitive to small changes in performance.

Methods: We asked 19,261 participants to complete a demographic questionnaire and 12 cognitive tests measuring aspects of executive function, including inhibitory control. We compared the performance of those reporting a history of concussion (post-concussion) to those reporting no history of concussion (non-concussed) on the cognitive battery and four non-cognitive variables.

Comparison of Magnetic Resonance Angiography and Computed Tomography Angiography Stereoscopic Cerebral Vascular Models.

In this paper, we will discuss and compare the stereoscopic models developed from two types of radiographic data, Magnetic Resonance Angiography (MRA) images and Computed Tomography Angiography (CTA) images. Stereoscopic models were created using surface or volume segmentation and semi-auto combined segmentation techniques. Although, the CTA data were found to improve the speed and quality of constructing virtual vascular models compared to conventional CT data, small blood vessels were difficult to capture during the imaging and reconstruction process thereby limiting the fidelity of the stereoscopic models.

Buccal injection of articaine to anesthetize the palatal mucosa.

Buccal and palatal injections are required for administration of anesthetic agents before maxillary tooth extractions, but palatal injections are painful for patients. Studies suggest that the palatal injection can be eliminated when articaine is delivered as a local anesthetic agent via buccal injection, but the anatomical mechanism for this effectiveness remains unclear. The objective of this study was to explore the potential mechanism by which buccal infiltration results in palatal anesthesia.

Wise interventions: Psychological remedies for social and personal problems.

Long-standing social problems such as poor achievement, personal and intergroup conflict, bad health, and unhappiness can seem like permanent features of the social landscape. We describe an approach to such problems rooted in basic theory and research in social psychology. This approach emphasizes subjective meaning-making-working hypotheses people draw about themselves, other people, and social situations; how deleterious meanings can arise from social and cultural contexts; how interventions to change meanings can help people flourish; and how initial change can become embedded to alter the course of people's lives.

Cross-cultural consistency and relativity in the enjoyment of thinking versus doing.

Which is more enjoyable: trying to think enjoyable thoughts or doing everyday solitary activities? Wilson et al. (2014) found that American participants much preferred solitary everyday activities, such as reading or watching TV, to thinking for pleasure. To see whether this preference generalized outside of the United States, we replicated the study with 2,557 participants from 12 sites in 11 countries.

Boring thoughts and bored minds: The MAC model of boredom and cognitive engagement.

What is boredom? We review environmental, attentional, and functional theories and present a new model that describes boredom as an affective indicator of unsuccessful attentional engagement in valued goal-congruent activity. According to the Meaning and Attentional Components (MAC) model, boredom is the result of (a) an attentional component, namely mismatches between cognitive demands and available mental resources, and (b) a meaning component, namely mismatches between activities and valued goals (or the absence of valued goals altogether). We present empirical support for four novel predictions made by the model: (a) Deficits in attention and meaning each produce boredom independently of the other; (b) there are different profiles of boredom that result from specific deficits in attention and meaning; (c) boredom results from two types of attentional deficits, understimulation and overstimulation; and (d) the model explains not only when and why people become bored with external activities, but also when and why people become bored with their own thoughts.

Prevalence-induced concept change in human judgment.

Why do some social problems seem so intractable? In a series of experiments, we show that people often respond to decreases in the prevalence of a stimulus by expanding their concept of it. When blue dots became rare, participants began to see purple dots as blue; when threatening faces became rare, participants began to see neutral faces as threatening; and when unethical requests became rare, participants began to see innocuous requests as unethical. This "prevalence-induced concept change" occurred even when participants were forewarned about it and even when they were instructed and paid to resist it.
