An experimental approach analyzing who sees disorder when there is nothing to see: understanding variance of perceptions via personal characteristics

Description
Knowing that disorder is related to crime, it has become essential for criminologists to understand how and why certain individuals perceive disorder.

Knowing that disorder is related to crime, it has become essential for criminologists to understand how and why certain individuals perceive disorder. Using data from the Perceptions of Neighborhood Disorder and Interpersonal Conflict Project, this study uses a fixed photograph of a neighborhood, to assess whether individuals "see" disorder cues. A final sample size of n=815 respondents were asked to indicate if they saw particular disorder cues in the photograph. The results show that certain personal characteristics do predict whether an individual sees disorder. Because of the experimental design, results are a product of the individual's personal characteristics, not of the respondent's neighborhood. These findings suggest that the perception of disorder is not as clear cut as once thought. Future research should explore what about these personal characteristics foster the perception of disorder when it is not present, as well as, how to fight disorder in neighborhoods when perception plays such a substantial role.

Somatosensory Modulation during Speech Planning

Previous studies have found that the detection of near-threshold stimuli is decreased immediately before movement and throughout movement production. This has been suggested to occur through the use of the internal forward model processing an efferent copy of the motor command and creating a prediction that is used to cancel out the resulting sensory feedback. Currently, there are no published accounts of the perception of tactile signals for motor tasks and contexts related to the lips during both speech planning and production. In this study, we measured the responsiveness of the somatosensory system during speech planning using light electrical stimulation below the lower lip by comparing perception during mixed speaking and silent reading conditions. Participants were asked to judge whether a constant near-threshold electrical stimulation (subject-specific intensity, 85% detected at rest) was present during different time points relative to an initial visual cue. In the speaking condition, participants overtly produced target words shown on a computer monitor. In the reading condition, participants read the same target words silently to themselves without any movement or sound. We found that detection of the stimulus was attenuated during speaking conditions while remaining at a constant level close to the perceptual threshold throughout the silent reading condition. Perceptual modulation was most intense during speech production and showed some attenuation just prior to speech production during the planning period of speech. This demonstrates that there is a significant decrease in the responsiveness of the somatosensory system during speech production as well as milliseconds before speech is even produced which has implications for speech disorders such as stuttering and schizophrenia with pronounced deficits in the somatosensory system.

This study analyzes the unconscious biases we have in terms of the amount of space we take up in social settings. 30 participants each have 10 minute conversations with another stranger while the amount of time they talk is calculated using momentary time sampling. Participants then estimate how much they talked, share how much they enjoyed the conversation, and take the Big 5 personality test. Results show that participants talked more than they thought by an average of 3.43% with an average difference in perception within each conversation being 15.5%. There was no significant correlation between enjoyment and personality or with percentage spoken and accuracy of the prediction, and those who were high in extraversion and agreeableness were closest in their perception of how much they listen.

The Wham-Womb Effect: Words with the Phoneme /æ/ are Rated as More Rousing than those with /u/

Description
Recent findings support that facial musculature accounts for a form of phonetic sound symbolism.

Recent findings support that facial musculature accounts for a form of phonetic sound symbolism. Yu, McBeath, and Glenberg (2019) found that, in both English words and Mandarin pinyin, words with the middle phoneme /i:/ (as in “gleam”) were rated as more positive than their paired words containing the phoneme /ʌ/ (as in “glum”). The present study tested whether a second largely orthogonal dimension of vowel phoneme production (represented by the phonemes /æ/ vs /u/), is related to a second dimension perpendicular to emotional valence, arousal. Arousal was chosen because it is the second dimension of the Russell Circumplex Model of Affect. In phonetic similarity mappings, this second dimension is typically characterized by oral aperture size and larynx position, but it also appears to follow the continuum of consonance/dissonance. Our findings supported the hypothesis that one-syllable words with the center vowel phoneme /æ/ were reliably rated as more rousing, and less calming, than matched words with the center vowel phoneme /u/. These results extend the Yu, et al. findings regarding the potential contribution of facial musculature to sounds associated with the emotional dimension of arousal, and further confirm a model of sound symbolism related to emotional expression. These findings support that phonemes are not neutral basic units but rather illustrate an innate relationship between embodied emotional expression and speech production.

The goal of the research is to assist Barrett Honors students at Arizona State University by generating a mindset that embraces feelings of stress rather than avoiding it. After data collection was complete, the researchers created a valuable and necessary field guide for ASU Barrett Faculty to provide for incoming students. The present study has been compiled to prove the importance of reframing one's perception of stress as an aid, reducing one's “symptomatic” perception of stress and experiencing life's stresses as challenges, and to cease living in a constant unhealthy state of fight or flight. The main research questions are: What is the average perceived stress level of Barrett Honors students and what information can ASU further provide incoming Barrett students that will alleviate overall perceived stress levels based on the data collection and field guide generated from the present study? The basis of the present study began with a survey compiled of demographic questions, questions relating to the Human Event (HE - a required honors course), and lastly the Perceived Stress Scale (PSS) developed by Sheldon Cohen, Tom Kamarck, and Robin Mermelstein, with slight modification for students relating to their perception of stress over the last semester. After survey responses were concluded, it was determined that the average perceived stress score among honors students was 18.57, shockingly lower than what was previously thought. The overall results of the PSS survey indicate that Barrett students are moderately stressed, disproving the researchers initial hypothesis that honors students perceived stress scores would be considered high on the PSS. The results did provide researchers with enough data to compile an incoming Barrett student field guide based on desired information reported in the survey. A discussion of the results explores the purpose of how the present study can be used in helping students with perceived stress, interpretations and significance of the data, correlation between academic success and perceived stress, major contributions to the study, and limitations and recommendations for future research.
