Description
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.

Description
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.

Description
Perceptions of neighborhood disorder have been studied by researchers in many ways since social disorganization theory was first introduced in the 1930s. However, few studies have focused explicitly on nonresident perceptions of neighborhood disorder. Further still, investigations regarding how race/ethnicity and gender may influence this population’s responses are also lacking in the present literature. This study intends to close some of the gap in this area of research.This study uses qualitative analysis to focus on Hispanic and Caucasian nonresidents’ responses to a single photographic stimulus. This study focuses on the following: (1) perception of neighborhood disorder, (2) gender-specific neighborhood perceptions of disorder, (3) inclusion of race-identifying words, specifically in terms of frequency among Hispanic respondents, and (4) prevalence of negative adjective use. Previous research has discovered that nonresidents have associated race with neighborhood disorder despite the absence of people in the surveying/data collection methods. By further investigating this topic, this research aims to analyze the responses more closely regarding the response affect (i.e., positive, neutral, and negative) with negative adjectives and race-identifying words. The findings from this study may encourage future investigation into implicit and explicit biases focused on the possible unconscious connection of race/ethnicity and neighborhood disorder in individual perceptions.
