Relational learning in children with deafness and cochlear implants

This four-experiment series sought to evaluate the potential of children with neurosensory deafness and cochlear implants to exhibit auditory-visual and visual-visual stimulus equivalence relations within a matching-to-sample format. Twelve children who became deaf prior to acquiring language (prelingual) and four who became deaf afterwards (postlingual) were studied. All children learned auditory-visual conditional discriminations and nearly all showed emergent equivalence relations. Naming tests, conducted with a subset of the children, showed no consistent relationship to the equivalence-test outcomes. This study makes several contributions to the literature on stimulus equivalence. First, it demonstrates that both pre- and postlingually deaf children can acquire auditory-visual equivalence relations after cochlear implantation, thus demonstrating symbolic functioning. Second, it directs attention to a population that may be especially interesting for researchers seeking to analyze the relationship between speaker and listener repertoires. Third, it demonstrates the feasibility of conducting experimental studies of stimulus control processes within the limitations of a hospital, which these children must visit routinely for the maintenance of their cochlear implants.     

EMERGENT CONDITIONAL RELATIONS IN A GO/NO‐GO PROCEDURE: FIGURE—GROUND AND STIMULUS‐POSITION COMPOUND RELATIONS

Past research has demonstrated emergent conditional relations using a go/no‐go procedure with pairs of figures displayed side‐by‐side on a computer screen. The present study sought to extend applications of this procedure. In Experiment 1, we evaluated whether emergent conditional relations could be demonstrated when two‐component stimuli were displayed in figure—ground relationships—abstract figures displayed on backgrounds of different colors. Five normally capable adults participated. During training, each two‐component stimulus was presented successively. Responses emitted in the presence of some stimulus pairs (A1B1, A2B2, A3B3, B1C1, B2C2 and B3C3) were reinforced, whereas responses emitted in the presence of other pairs (A1B2, A1B3, A2B1, A2B3, A3B1, A3B2, B1C2, B1C3, B2C1, B2C3, B3C1 and B3C2) were not. During tests, new configurations (AC and CA) were presented, thus emulating structurally the matching‐to‐sample tests employed in typical equivalence studies. All participants showed emergent relations consistent with stimulus equivalence during testing. In Experiment 2, we systematically replicated the procedures with stimulus compounds consisting of four figures (A1, A2, C1 and C2) and two locations (left — B1 and right — B2). All 6 normally capable adults exhibited emergent stimulus—stimulus relations. Together, these experiments show that the go/no‐go procedure is a potentially useful alternative for studying emergent conditional relations when matching‐to‐sample is procedurally cumbersome or impossible to use.     

Associative symmetry by pigeons after few-exemplar training

The present experiment investigated whether pigeons can show associative symmetry on a two-alternative matching-to-sample procedure. The procedure consisted of a within-subject sequence of training and testing with reinforcement, and it provided (a) exemplars of symmetrical responding, and (b) all prerequisite discriminations among test samples and comparisons. After pigeons had learned two arbitrary-matching tasks (A-B and C-D), they were given a reinforced symmetry test for half of the baseline relations (B1-A1 and D1-C1). To control for the effects of reinforcement during testing, two novel, nonsymmetrical responses were concurrently reinforced using the other baseline stimuli (D2-A2 and B2-C2). Pigeons matched at chance on both types of relations, thus indicating no evidence for symmetry. These symmetrical and nonsymmetrical relations were then directly trained in order to provide exemplars of symmetry and all prerequisite discriminations for a second test. The symmetrical test relations were now B2-A2 and D2-C2 and the nonsymmetrical relations were D1-A1 and B1-C1. On this test, 1 pigeon showed clear evidence of symmetry, 2 pigeons showed weak evidence, and 1 pigeon showed no evidence. The previous training of all prerequisite discriminations among stimuli, and the within-subject control for testing with reinforcement seem to have set favorable conditions for the emergence of symmetry in nonhumans. However, the variability across subjects shows that methodological variables still remain to be controlled.     

Trash talk in a competitive setting: Impact on self‐efficacy and affect

The effects of trash talk and competition outcome on self‐efficacy and affect were examined in 40 Madden? NFL 08 football video game players randomly assigned to two conditions: silence talk, where they played the first game in complete silence; and the second trash talking. Measures of self‐efficacy, positive affect (PA), and negative affect (NA) were administered. Results revealed that players enforced to be silent in the first game instantaneously exhibited lower self‐efficacy, lower PA, and higher NA than players permitted to talk in Game 1. However, players subsequently instructed to remain silent in the second game showed markedly decreased self‐efficacy compared to players permitted to talk in Game 2. Results are interpreted in light of the social‐cognitive‐motivational theory.     

When News Meets the Audience: How Audience Feedback Online Affects News Production and Consumption

Innovations in communication technology have changed the way news is produced and consumed. Various digital platforms, ranging from news websites to social media sites to personal blogs, have enabled news users to indicate how much they like the news they have read, to share it with others, and to leave comments. News users' mouse clicks are automatically recorded and aggregated by computational systems and made publicly visible (e.g., “Most Read Articles”). This essay reviews the ever‐growing research on how audience feedback online, a hybrid form of interpersonal and mass communication, alters various stages of news production and influences the way people select, process, and make sense of the news. Future research agendas are proposed.     

Women's Sexual Health: The Need for Feminist Analyses in Public Health in the Decade of Behavior

Women's sexual health is directly affected by women's low status in society. This low status, and subsequent lack of sexual autonomy, not only increases risk for sexual health problems, it also decreases ability to obtain treatment and support when a sexual health concern arises. This has clearly been demonstrated in the HIV epidemic within the U.S.. Earlier in the epidemic, women were simply ignored by public health research and practice. Once they could no longer be ignored, they were blamed and viewed as vectors. Current seroprevalence rates among men reveal that women are not significant vectors. In contrast, rates among women indicate that infection from men is the primary mechanism by which women are contracting HIV, and male-controlled sexual decision-making, male partner violence against women, and histories of sexual assault all contribute to increased HIV risk for women. Once infected, women are not given the support and resources they need as mothers and caretakers of HIV-positive partners and/or children. These findings are especially true for marginalized women such as women of color, poor women, women addicted to alcohol or drugs, and women who exchange sex for drugs or money. Findings from this review demonstrate the need for feminist approaches in understanding and addressing this issue in the Decade of Behavior. Such approaches must include an understanding of the needs of diverse women. An empowerment approach is needed to better contend with the sexual health needs of women; this must include the goal of ensuring women's control of their own bodies.
