Is It Abuse? Deaf Female Undergraduates' Labeling Of Partner Violence, Melissa Anderson, Caroline Kobek Pezzarossi
Is It Abuse? Deaf Female Undergraduates' Labeling Of Partner Violence, Melissa Anderson, Caroline Kobek Pezzarossi
Melissa L. Anderson
The current study investigated the labeling of abuse experiences in a sample of 97 Deaf female undergraduate students, exploring the following questions: What is the prevalence of violent behaviors experienced by Deaf female undergraduates in their past-year relationships, what proportion of these relationships are identified as "abuse," and what scripts and strategies do Deaf female undergraduates utilize to label their experiences of partner violence? Results indicated that over half of the sample chose not to label past-year experiences of psychological aggression, physical assault, and sexual coercion as abuse, even when these experiences included severe violence. Implications for the Deaf education …
Intimate Partner Violence Against Deaf Female College Students, Melissa Anderson, Irene Leigh
Intimate Partner Violence Against Deaf Female College Students, Melissa Anderson, Irene Leigh
Melissa L. Anderson
It has been estimated that roughly 25% of all Deaf women in the United States are victims of intimate partner violence (Abused Deaf Women's Advocacy Services [ADWAS]), a figure similar to annual prevalence rates of 16% to 30% for intimate partners in the general population. One goal of the present study was to ascertain the prevalence of intimate partner violence victimization in a sample of Deaf female college students. When comparing the prevalence of physical assault, psychological aggression, and sexual coercion victimization to hearing female undergraduates, the current sample was approximately two times as likely to have experienced victimization in …

Black Deaf Individuals' Reading Skills: Influence Of Asl, Culture, Family Characteristics, Reading Experience, And Education, Candace Myers, M. Diane Clark, Millicent Musyoka, Melissa Anderson, Gizelle Gilbert, Selina Agyen, Peter Hauser
Melissa L. Anderson
Previous research on the reading abilities of Deaf individuals from various cultural groups suggests that Black Deaf and Hispanic Deaf individuals lag behind their White Deaf peers. The present study compared the reading skills of Black Deaf and White Deaf individuals, investigating the influence of American Sign Language (ASL), culture, family characteristics, reading experience, and education. (The descriptor Black is used throughout the present article, as Black Deaf individuals prefer this term to African American. For purposes of parallel construction, the term White is used instead of European American.) It was found that Black Deaf study participants scored lower on …

2012-Limited research exists examining the effect of moderately loaded conditioning activities that are employed as part of a strength-power potentiating complex (SPPC). Additionally, no studies to date have explored the effects of using a concentric-only quarter back squat protocol as part of an SPPC. Therefore, the purpose of this study was to examine the effects of a moderately loaded (50-65% of 1RM) concentric-only quarter back squat protocol on the occurrence of potentiation effects at various time points. Twenty men who could quarter back squat a minimum of 2.4 times their body mass (3.7 ±: 0.7 kg-per body mass) participated in …

The Role Of Vision In Detecting And Correcting Fingertip Force Errors During Object Lifting, Gavin Buckingham, Nathalie Ranger, Melvyn Goodale
The Role Of Vision In Detecting And Correcting Fingertip Force Errors During Object Lifting, Gavin Buckingham, Nathalie Ranger, Melvyn Goodale
Gavin Buckingham
Vision provides many reliable cues about the likely weight of an object, allowing individuals to predict how heavy it will be. The forces used to lift an object for the first time reflect these predictions. This, however, leads to inevitable errors during lifts of objects that weigh unexpected amounts. Fortunately, these errors are rarely made twice in a row-lifters have the impressive ability to detect and correct large or small misapplications of fingertip forces, even while experiencing weight illusions. Although it has been assumed that we detect and correct these errors exclusively with our sense of touch, recent evidence has …
The Material-Weight Illusion Induced By Expectations Alone, Gavin Buckingham, Nathalie Ranger, Melvyn Goodale
The Material-Weight Illusion Induced By Expectations Alone, Gavin Buckingham, Nathalie Ranger, Melvyn Goodale
Gavin Buckingham
In the material-weight illusion (MWI), equally weighted objects that appear to be made from different materials are incorrectly perceived as having different weights when they are lifted one after the other. Here, we show that continuous visual experience of the lift is not a prerequisite for this compelling misperception of weight; merely priming the lifters' expectations of heaviness is sufficient for them to experience a robust MWI. Furthermore, these expectations continued to influence the load force used to lift MWI-inducing stimuli trial after trial, supporting the notion that vision plays an important role in the skillful lifting of objects.
The Influence Of Competing Perceptual And Motor Priors In The Context Of The Size-Weight Illusion, Gavin Buckingham, Melvyn Goodale
The Influence Of Competing Perceptual And Motor Priors In The Context Of The Size-Weight Illusion, Gavin Buckingham, Melvyn Goodale
Gavin Buckingham
When lifting objects of identical mass but different sizes, people perceive the smaller objects as weighing more than the larger ones (the 'size-weight' illusion, SWI). While individual's grip and load force rates are rapidly scaled to the objects' actual mass, the magnitude of the force used to lift these SWI-inducing objects is rarely discussed. Here, we show that participants continue to apply a greater loading force to a large SWI-inducing cube than to a small SWI cube, lift after lift. These differences in load force persisted long after initial errors in grip and load force rates had been corrected. Interestingly, …
Gating Of Vibrotactile Detection During Visually Guided Bimanual Reaches, Gavin Buckingham, David Carey, Francisco Colino, John Degrosbois, Gordon Binsted
Gating Of Vibrotactile Detection During Visually Guided Bimanual Reaches, Gavin Buckingham, David Carey, Francisco Colino, John Degrosbois, Gordon Binsted
Gavin Buckingham
It is far more difficult to detect a small tactile stimulation on a finger that is moving compared to when it is static. This suppression of tactile information during motion, known as tactile gating, has been examined in some detail during single-joint movements. However, the existence and time course of this gating has yet to be examined during visually guided multi-joint reaches, where sensory feedback may be paramount. The current study demonstrated that neurologically intact humans are unable to detect a small vibratory stimulus on one of their index fingers during a bimanual reach toward visual targets. By parametrically altering …
Living In A Material World: How Visual Cues To Material Properties Affect The Way That We Lift Objects And Perceive Their Weight, Gavin Buckingham, Jonathan Cant, Melvyn Goodale
Living In A Material World: How Visual Cues To Material Properties Affect The Way That We Lift Objects And Perceive Their Weight, Gavin Buckingham, Jonathan Cant, Melvyn Goodale
Gavin Buckingham
The visual properties of an object provide many cues as to the tensile strength, compliance, and density of the material from which it is made. However, it is not well understood how these implicit associations affect our perceptions of these properties and how they determine the initial forces that are applied when an object is picked up. Here we examine the effects of these cues on such forces by using the classic "material-weight illusion" (MWI). Grip and load forces were measured in three experiments as participants lifted cubes made from metal, wood, and expanded polystyrene. These cubes were adjusted to …
Rightward Biases During Bimanual Reaching, Gavin Buckingham, David Carey
Rightward Biases During Bimanual Reaching, Gavin Buckingham, David Carey
Gavin Buckingham
Two experiments were carried out to investigate whether attention is biased toward the right hand of right handers during bimanual coordination (Peters 1981). A novel discontinuous double-step reaching task was developed, where right-handed participants executed a bimanual reach followed by a left or right hand unimanual reach. Asymmetries in the downtime between the bimanual and unimanual reach portions (the refractory period) were used to infer the direction of attention. A shorter right hand refractory period was found in the first experiment, indicating a rightward bias in attention. In a second experiment, shifting the focus of attention during the bimanual portion …
