The influence of visual flow and perceptual load on locomotion speed

Visual flow is used to perceive and regulate movement speed during locomotion. We assessed the extent to which variation in flow from the ground plane, arising from static visual textures, influences locomotion speed under conditions of concurrent perceptual load. In two experiments, participants walked over a 12-m projected walkway that consisted of stripes that were oriented orthogonal to the walking direction. In the critical conditions, the frequency of the stripes increased or decreased. We observed small, but consistent effects on walking speed, so that participants were walking slower when the frequency increased compared to when the frequency decreased. This basic effect suggests that participants interpreted the change in visual flow in these conditions as at least partly due to a change in their own movement speed, and counteracted such a change by speeding up or slowing down. Critically, these effects were magnified under conditions of low perceptual load and a locus of attention near the ground plane. Our findings suggest that the contribution of vision in the control of ongoing locomotion is relatively fluid and dependent on ongoing perceptual (and perhaps more generally cognitive) task demands.     

Patient Perspectives on Intimate Partner Violence Discussion during Genetic Counseling Sessions

Intimate partner violence (IPV) is a major health concern in the United States (ACOG 2013). The World Health Organization (WHO) describes IPV as any physical, sexual, psychological harm by a current or former intimate partner (WHO 2016). Due to the psychosocial depth and nature of discussions within genetic counseling sessions, patients may disclose and/or discuss IPV as it relates to sexual well-being, reproductive and overall health. This study aims to assess the role for IPV screening, counseling and intervention in genetic counseling practice by investigating the incidence, experiences and attitudes about IPV among genetic counseling patients. Patients receiving genetic counseling at an urban metropolitan hospital were anonymously surveyed about experiences and perspectives on IPV as a topic of discussion during genetic counseling sessions. Among 60 eligible patients, 50 completed the survey (49 females, 1 male, of which, 5 identified as LGBT) ages 20 to 66. The incidence of IPV in this group was 16.0 % (n = 8). Majority of participants had never been asked about IPV by a healthcare provider (n = 32; 64.0%), would have felt comfortable answering questions about IPV by their healthcare provider (n = 34; 68.0%), and would have felt comfortable answering questions about IPV by their genetic counselor (n = 39; 78.0%). Perspectives from all participants, notably those with IPV history, provided insights to the role of genetic counselors in areas for IPV screening and counseling training.     

Understanding black issues in postgraduate counsellor training

This paper presents a brief account of a qualitative multicultural study and heuristic exploration of how trainee counsellors understand black issues in their training and in their therapeutic work with clients. This initiative is supported by a previous survey of black clients and therapists who suggest that changes are needed in training. It presents current legislation and need for equalities in Higher Education and counsellor training, by challenging the dominance of Eurocentric approaches. A pluralistic, flexible Action Research methodology will be outlined. The theory and context of previous studies are presented. Phases of the process are described to show how this study was approached. Phase one describes how interviews with a variety of experienced practitioners confirmed the need for the study. Using examples of trainees’ narratives, phase two describes how the phenomenon of black issues was integrated into training and the process of generating data. The paper shows how the explication process reveals elements of fear, history, guilt and racism, present in the dynamic of black issues. The paper highlights how racism features highly in trainees’ concerns and influences their ability to share and understand. A snapshot of emerging concepts such as ‘finding a voice’ and ‘recognition trauma’ which are developed to assist the reflexive process is featured. The role of the researcher and black trainees as ‘black expert’ is discussed. In the context of ethical concerns and working through the researcher's counter transference as a black female tutor researcher, the process of modelling within a participatory role is described. An excerpt from a discussion with colleagues gives an essence of the outcome. The outcome is summarised in the conclusion:'A bridge from fear to transformation’. The study enabled both trainees and staff as collaborators to shift from a position of fear and not knowing to engaging in active dialogue about black issues on a personal and professional basis.     

Culturally Sensitive Risk Behavior Prevention Programs for African American Adolescents: A Systematic Analysis

The current review conducted a systematic assessment of culturally sensitive risk prevention programs for African American adolescents. Prevention programs meeting the inclusion and exclusion criteria were evaluated across several domains: (1) theoretical orientation and foundation; (2) methodological rigor; (3) level of cultural integration; (4) program target or domain (e.g., schools, communities, families); (5) outcome change level assessed (e.g., addressing change in beliefs/values or behaviors); and (6) program effects on risk behaviors. Thirteen studies (N = 13) with adolescent participants ranging from 10 to 18 years were identified and evaluated. Analyses suggested that more effective culturally sensitive risk prevention programs included the following: (1) a clearly articulated theoretical orientation, which utilized both universal (e.g., behavioral theories) and culturally specific (e.g., Africultural theories) frameworks; (2) a rigorous methodological design (e.g., inclusion of control group, utilization of program manuals, valid and reliable study measures); (3) an integration of culture at multiple levels (e.g., accessibility, delivery, and content) of programming; (4) consideration of the influence of multiple contexts and domains (e.g., family, community, school); (5) multiple behavior change outcomes (e.g., behaviors, relationships, values); and (6) sustained program effects over time. Recommendations for increasing the effectiveness and efficacy of culturally sensitive prevention programs are discussed.     

Linking social history and the therapeutic process in research and practice on black issues

This paper shares a first time experience of presenting a workshop at the 2002 BACP Research Conference. It highlights issues arising from the beginnings of research into the process of therapy in relation to black issues. The findings of two studies are reported in brief. Questions raised by workshop participants, and the low participation in the workshop session, are used as a means of illustrating the ambivalence that exists in the counselling and psychotherapy world in respect of this topic. It is argued that a historical perspective may assist the development of clinical responses to black issues, and that the effective exploration of black issues can be used as a vehicle to explore issues pertaining to all minority groups and their experiences.     

Understanding the Relationship between Religiosity and Caregiver–Adolescent Communication About Sex within African-American Families

Caregiver–adolescent communication about sex plays a critical role in the sexual socialization of youth. Many caregivers, however, do not engage their youth in such conversations, potentially placing them at risk for negative sexual health outcomes. Lack of caregiver–adolescent communication about sex may be particularly harmful for rural African American youth, as they often report early sex initiation and are disproportionately impacted by STIs. Moreover, sexual communication may be particularly challenging for families with strong religious backgrounds, potentially affecting the occurrence and breadth of topics covered during communication. Study aims were to: determine whether there was a relationship between caregiver religiosity and type of topics covered during communication about sex (e.g., general sexual health vs. positive aspects of sexuality) among 435 caregivers of early adolescent, African American youth; and if so, identify factors that might explain how religiosity affects communication about sex. Results indicated that caregiver religiosity was positively associated with communication about general, but not positive aspects of sexuality for caregivers of males. Attitudes towards communication about sex and open communication style mediated the relationship. There was no association between religiosity and communication about sex for caregivers of females. The findings from this study could provide a base to better understand and support the sexual socialization process within religious, African American families.     

Control of appetitive and aversive taste-reactivity responses by an auditory conditioned stimulus in a devaluation task: a FOS and behavioral analysis

Through associative learning, cues for biologically significant reinforcers such as food may gain access to mental representations of those reinforcers. Here, we used devaluation procedures, behavioral assessment of hedonic taste-reactivity responses, and measurement of immediate-early gene (IEG) expression to show that a cue for food engages behavior and brain activity related to sensory and hedonic processing of that food. Rats first received a tone paired with intraoral infusion of sucrose. Then, in the absence of the tone, the value of sucrose was reduced (Devalue group) by pairing sucrose with lithium chloride (LiCl), or maintained (Maintain group) by presenting sucrose and LiCl unpaired. Finally, taste-reactivity responses to the tone were assessed in the absence of sucrose. Devalue rats showed high levels of aversive responses and minimal appetitive responses, whereas Maintain rats exhibited substantial appetitive responding but little aversive responding. Control rats that had not received tone-sucrose pairings did not display either class of behaviors. Devalue rats showed greater FOS expression than Maintain rats in several brain regions implicated in devaluation task performance and the display of aversive responses, including the basolateral amygdala, orbitofrontal cortex, gustatory cortex (GC), and the posterior accumbens shell (ACBs), whereas the opposite pattern was found in the anterior ACBs. Both Devalue and Maintain rats showed greater FOS expression than control rats in amygdala central nucleus, GC, and both subregions of ACBs. Thus, through associative learning, auditory cues for food gained access to neural processing in several brain regions importantly involved in the processing of taste memory information.     

Daily Hassles and African American Adolescent Females�� Psychological Functioning: Direct and Interactive Associations with Gender Role Orientation

Given that stressors may accumulate across the life span, the extent to which daily hassles are associated with African American females?? psychological functioning during the adolescent years remains an important question. Understanding the potential impact of daily hassles is important due to indications that African American women report greater daily hassles and have higher incidence rates of stress-related disorders. The current study examines the relationship between daily hassles and psychological functioning (e.g., depression and anxiety symptoms) among 103 U.S. African American adolescent females (M?=?15.50; SD?=?1.70) residing in a moderately-sized Midwestern city. Additionally, this investigation explores gender role orientation as a moderator of this relationship. Results indicated that increased daily hassles were associated with greater depressive and anxiety symptoms. Also, this investigation provides some support for the direct and moderating role of gender role orientation. A greater feminine or androgynous role orientation was associated with fewer depressive and anxiety symptoms. In addition, although not directly associated, this investigation indicated that a masculine role orientation moderated the association between daily hassles and girls?? psychological outcomes. Specifically, among African American adolescent females with a greater masculine role orientation, increased daily hassles were associated with reduced psychological functioning (e.g., greater depressive and anxiety symptoms). Neither feminine nor androgynous role orientation, however, moderated the relationship between daily hassles and psychological functioning (e.g., depressive and anxiety symptoms). Implications of findings are discussed.     

Amount of training and cue-evoked taste-reactivity responding in reinforcer devaluation

In two experiments, rats received minimal (16) pairings of one auditory conditioned stimulus (CS) cue with a sucrose reinforcer, and extensive (112) pairings of another auditory CS with that reinforcer. After sucrose was devalued by pairing it with lithium chloride in some rats (Devalue groups) but not others (Maintain groups), taste reactivity (TR) and other responses to unflavored water were assessed in the presence of the auditory CSs alone. The minimally trained CS controlled substantially more evaluative TR responses than the extensively trained CS. Those TR responses were hedonic (positive) in the Maintain groups, but aversive (negative) in the Devalue groups. By contrast, food cup entry and other responses thought not to reflect evaluative taste processing were controlled more by the extensively trained cue. These responses were reduced by sucrose devaluation comparably, regardless of the amount of training. The results suggest rapid changes in the content of learning as conditioning proceeds. Early in training, CSs may be capable of activating preevaluative processing of an absent food reinforcer that includes information about its palatability, but that capability is lost as training proceeds.     

Racial Discrimination and African American Adolescents’ Adjustment: Gender Variation in Family and Community Social Support, Promotive and Protective Factors

The current investigation explores the promotive and protective role of family and community-specific social support on the association between perceived racial discrimination and African American adolescents’ adjustment (e.g., depressive symptoms, school suspensions, school engagement). One thousand nine-hundred forty-two African American adolescents (ages 12–18, M = 15.12; SD = 1.83; 59 % female) from a large Midwestern city participated in this investigation. Regression analyses revealed that perceived racial discrimination was associated with less positive adjustment outcomes for boys and girls. Additionally, there was partial support for gender variation in the promotive role of social support and adolescent adjustment. In particular, while only maternal support was associated with boys’ adjustment, both maternal and paternal support was associated with girls’ adjustment. Also, there was partial support for gender differentiation in the strength and directionality of protective factors. Though in an unpredicted direction, father support moderated the relationship between perceived racial discrimination and girls’ adjustment. Community supports (religious connection and mentor presence) emerged as protective factors for boys’. Findings highlight the role of gender in understanding potential promotive and protective factors for African American adolescents.
