Suppression of optokinesis by a stabilized target: effects of instruction and stimulus frequency.

Subjects viewed a foveally stabilized target presented against a background field of dots moving sinusoidally. Several different modes of viewing the target were used (subjects were instructed to gaze, look, or hold), and the frequency of sinusoidal field motion was varied from 1/32 to 2 Hz. In line with previous findings, the presence of a stabilized target resulted in substantial suppression of optokinesis. The characteristics of this suppression (gain and phase of slow residual eye movements) were dependent on both the mode of viewing the target and the frequency of field motion. When subjects used an imaginary target, little suppression occurred. These findings provide an overall profile of dynamic characteristics of mechanisms involved in the suppression of optokinesis. They support the view that this suppression is significantly determined by the presence of a target against a moving background (even without retinal slip), and by the mode of attending to the target.     

Ethical issues in the application of medical technology to paediatric intensive care: two views of the newborn

Recent advances in medical technology have led to a marked improvement in the chances of survival of sick or preterm infants, thereby stimulating renewed ethical debate on the status of the newborn. Two contradictory attitudes to the medical care of preterm or congenitally malformed newborn infants can be discerned in our pluralistic society. The two attitudes have their historical roots in the classical Graeco-Roman and Judaeo-Christian ethical traditions respectively. The former views newborn infants as of potential value only whereas the latter emphasises the intrinsic worth and dignity of the individual made in God's image. Recent secular philosophical reflection has provided a rationale for infanticide of the sick or abnormal newborn. A Christian approach to the care of the newborn prohibits intentional killing yet may encompass the withdrawal of treatment that is inappropriate or unduly burdensome. Medical care should be based upon respect for the value of the individual, protection of the defenceless from abuse or exploitation, and wise stewardship of limited health-care resources.     

THE EFFECTS OF CHILDHOOD SEXUAL MESSAGES ON AFRICAN-AMERICAN AND WHITE WOMEN'S ADOLESCENT SEXUAL BEHAVIOR

To clarify the relationship between sexual communication and sexual behavior, multiple components of sexual messages recalled from child hood were examined in a community sample of 248 African-American and White women. Respondents were matched on a predesignated set of demographic variables and were interviewed using the Wyatt Sexual History Questionnaire. We anticipated that women's recollections of messages from parents and television would differ both individually and across ethnicity, and that messages recalled from parents would be multidimensional, varying in tone (positive vs. negative) across time (childhood vs. adolescence) and form (verbal vs. nonverbal). We also expected that the presence and tone of specific types of messages re called would be associated with risk-related sexual behavior. Results confirmed predictions concerning differential interpretations of messages, and ethnicity emerged as a strong mediating variable. The implications of the specific types of parental messages influencing behavior are discussed.     

Slurs,roles and power

Slurring is a kind of hate speech that has various effects. Notable among these is variable offence. Slurs vary in offence across words, uses, and the reactions of audience members. Patterns of offence aren’t adequately explained by current theories. We propose an explanation based on the unjust power imbalance that a slur seeks to achieve. Our starting observation is that in discourse participants take on discourse roles. These are typically inherited from social roles, but only exist during a discourse. A slurring act is a speech-act that alters the discourse roles of the target and speaker. By assigning discourse roles the speaker unjustly changes the power balance in the dialogue. This has a variety of effects on the target and audience. We show how these notions explain all three types of offence variation. We also briefly sketch how a role and power theory can help explain silencing and appropriation. Explanatory power lies in the fact that offence is correlated with the perceived unjustness of the power imbalance created.     

Using computer‐assisted instruction to increase the eye gaze of children with autism

Many children diagnosed with autism spectrum disorders have difficulty making appropriate eye contact and engaging in joint attention. The current study evaluated a computer‐assisted instruction package (pairing visual stimuli with vocal stimuli) as a novel treatment to improve the eye gaze accuracy in 3 elementary school children with autism. The researchers measured the latency from a recorded verbal stimulus to the students making eye contact with pictures of familiar individuals displayed on a computer screen, and the duration for which eye gaze on the stimulus was maintained. An automated infrared camera system for measuring eye gaze was utilized that eliminated the need for an instructor to make subjective judgments regarding participants' eye gaze. For all three participants, duration of eye contact increased, and latency to responding decreased following exposure to the computer‐assisted instruction. The implications of these findings for the treatment of individuals with autism are discussed, along with suggestions for future research on the topic.     

Mozambican immigrants to South Africa: Their xenophobia and discrimination experiences

We explored Mozambican immigrants’ lived experiences of xenophobia and discrimination in South Africa. Informants were 15 Mozambican immigrants (female = 7, male = 8) living in an informal settlement in Zandspruit, Gauteng Province. They completed open-ended written narratives on xenophobic and discriminatory experiences. Following thematic analysis, we identified three themes to characterise the Mozambican immigrants’ experiences of xenophobia and discrimination: (i) abusive attitudes, (ii) ethnic discrimination, and (iii) scapegoating. The Mozambican immigrants’ experiences of xenophobia and discrimination are consistent with findings from the extant international literature on ingroup/outgroup social strife with real or perceived scarcity of resources.     

Candidate Effects on Election Outcomes: Political Skill,Campaign Efficacy,and Intentions in a British General Election

Integrating Social/Political Influence Theory with the Theory of Planned Behavior, we argue that personal resources (i.e., political skill, self-efficacy) enable political candidates to form more ambitious campaign intentions, and thus perform better in elections. We tested this model with a sample of political candidates (N = 225) campaigning in a British general election. Three months before polling day, candidates provided self-ratings of political skill, domain-specific self-efficacy (i.e., campaign efficacy), and personal campaign intentions during the campaign period. Our results demonstrated that political skill was positively related to campaign efficacy, and intentions, via campaign efficacy. We also found a significant indirect effect for political skill on electoral performance (i.e., percentage of the vote), through campaign efficacy and intentions. Implications of our results for understanding candidate effects in campaigns and future research are discussed.     

RECONCEPTUALIZING ISSUES THAT AFFECT WOMEN'S SEXUAL DECISION-MAKING AND SEXUAL FUNCTIONING

This paper addresses five existing societal myths and their underlying faulty assumptions about women's sexuality. The following myths are examined: (a) women possess adequate sexual knowledge to understand their sexual needs, (b) they know how to communicate about sex, (c) they engage in sex because they want to do so, (d) if they are sexually active, they enjoy sex, and (e) they use their knowledge of sex to protect themselves from sexually transmitted diseases and pregnancy. These myths need to be considered when conducting research and developing interventions designed to decrease women's sexual risk-taking. Research that assesses women's levels of factual sexual knowledge, comfort and skills discussing sexual information, and literacy is needed. The importance of examining ethnic, cultural, economic, religious, relationship factors, and psychological issues is discussed in order to encourage research relevant to women's sexual decision-making.     

Priming effects for affective vs. neutral faces

Affective and Neutral Tasks (faces with negative or neutral content, with different lighting and orientation) requiring reaction time judgments of poser identity were administered to 32 participants. Speed and accuracy were better for the Affective than Neutral Task, consistent with literature suggesting facilitation of performance by affective content. Priming effects were significant for the Affective but not Neutral Task. An Explicit Post-Test indicated no conscious knowledge of the stimulus frequency that was associated with performance facilitation. Faster performance by female vs. male participants, and differential speeds and susceptibility to priming of different emotions were also found. Anger and shock were responded to most rapidly and accurately in several conditions, showed no gender differences, and showed significant priming for both RT and accuracy. Fear and pain were responded to least accurately, were associated with faster female than male reaction time, and the accuracy data showed a kind of reverse priming.
