Possible olfaction-based mechanisms in human kin recognition and inbreeding avoidance

Three studies explored kin recognition through olfaction. In Study I, adults (N=22) were tested for ability to identify the odors of themselves; their mother; their father; a sister; a brother; a familiar, unrelated individual; and a stranger. Acquaintances were identified as accurately as biological kin, implicating an association mechanism. However, biological kin were often confused, implicating phenotypic matching. Same-sex kin were confused more than opposite-sex kin, but mainly when same-sex kin had odors of similar intensity. Study II implicated phenotypic matching. Mothers (N=18) could identify their biological children but not their stepchildren. The preadolescent children (N=37) identified their full siblings but not half-siblings or stepsiblings. Thus, olfactory cues may help mediate favoritism of blood relatives. In Study III, mutual olfactory aversion occurred only in the father-daughter and brother-sister nuclear family relationships. Recognition occurred between opposite-sex siblings but not same-sex siblings. Thus, olfaction may help mediate the development of incest avoidance during childhood (the Westermarck effect).     

Evaluating sex discrimination claims: the mediating role of attributions.

The role of attributions in judgments of sex discrimination was examined in 2 laboratory experiments. In Study 1, participants read 1 of 12 brief scenarios in which limited information about the strength of evidence against a fictitious corporation and occupational gender stereotype were manipulated. Results suggested that attributions mediated the relationships between participants' gender, strength of evidence, and discrimination judgments. In Study 2, participants were provided with 1 of 3 detailed, typewritten summaries of evidence presented in a sex discrimination trial. Results indicated that jurors' gender was again significantly related to attributions and to sex discrimination judgments even in the face of substantial objective information related to the case. The variance in observers' judgments associated with gender, however, appeared to be greatest when information about the organization's guilt or innocence was equivocal.     

George Steiner's Wager On Transcendence

The paper seeks to explore the roots of Steiner's thought and particularly the theme of transcendence understood in terms of the mystery of immanence he expresses in terms of real presence. Steiner sees a significant breaking of the classic covenant between word and world occurring in the later nineteenth century. This insight, I suggest, is reinforced by a consideration of the distinction between such thinkers as Ruskin and Nietzsche and a way out of the dilemma is plotted by the linguistic philosophy which takes its cue from the work of Frege. One of the significant influences on the work of Steiner seems to be Heidegger. His study of Heidegger leads him to a consideration of language and an attempt to offer an argument for transcendence from a linguistic context. This paper suggests that Steiner offers a late twentieth-century, linguistic version of Aquinas's Five Ways, a movement from the agnosticism of 'I do not know' to the affirmation 'there is an Unknown'. Steiner argues that we come to a sense of this transcendence in the mystery of human creativity. This is a discovery made in the midst of the ordinary business of human living. It is significant, however, that the sense of Being that we encounter as we mediate on the act of artistic creation seems not to be an attempt to argue for a restatement of the ontological argument. Nietzsche's lesson has to be learnt: God cannot be talked of as an object, his presence cannot be indicated by way of ostensive definition. Steiner offers a context which allows for an encounter with the mystery of God but this encounter remains purely gratuitous.     

Hand-hemispace spatial compatibility,precueing, and stimulus-onset asynchrony

Summary The role of attention and the resolution of coding conflicts in hand-hemispace spatial-compatibility effects was examined in a precueing experiment in which visual and vibrotactile precues, with various stimulus-onset asynchronies (SOAs), were presented in blocked and random order. It was expected that precues at the shorter SOAs would fail to facilitate the shifting of attention, as they occur too close to the imperative stimulus to be informative. The task would therefore approximate one of choice reaction time (RT), resulting in a hand-hemispace spatial-compatibility effect. Conversely, the longer SOAs would provide the subject with sufficient time in which to shift attention fully, and would therefore result in a task more like that of simple reaction time (SRT). It was expected that the hand-hemispace spatial-compatibility effect would then be absent. As was expected, this effect was present at the shorter SOAs, and absent at the longer SOAs. In Experiments 2 and 3, provision of a visual precue further facilitated attentional deployment, as did blocking the presentation of various SOAs in Experiment 3. Vibrotactile and visual precues did not differ in their ability to direct attention, implying that these modalities orient attention and precue location in essentially similar ways. These findings are discussed within the context of the mechanisms thought to underlie the time course of spatial compatibility and the dissipation of a fading trace of interfering spatial codes.     

Computer-based career planning for adults

The Career Information and Planning System is described. Designed for officers of the United States Army, it is a computer-based counselling and guidance system which aims to enhance the career planning skills of adults.     

Predicting negotiation skills

The purpose of this study was to validate a selection process that was designed to predict negotiation skills for a telephone collections job. First, a job analysis was performed (n=343) to identify the major functions and behavioral requirements of the job. Next, the test, a situational judgment inventory, was developed, and a concurrent criterion related validation study was completed (n=249). The criterion measures were supervisory ratings of performance. Validity coefficients ranged from r=.41 (p<.001) to r=.45 (p<.001). In conclusion, the situational judgment inventory was found an effective vehicle for measuring telephone negotiation skills.     

TEACHING PERSONS WITH PROFOUND MULTIPLE HANDICAPS: A REVIEW OF THE EFFECTS OF BEHAVIORAL RESEARCH

The behavioral research on teaching individuals who have profound multiple handicaps is reviewed. The primary focus is on determining the degree to which behavioral research has demonstrated the teaching of meaningful skills to this population. Results of the review indicate that investigations have demonstrated, albeit inconsistently, that behavior change has resulted from contingency management interventions with persons who have profound multiple handicaps. However, there is little evidence that such interventions have resulted in meaningful behavior change according to currently accepted criteria for beneficially affecting the quality of life of persons with serious handicaps. Potential explanations for the lack of such evidence are offered, including the relative lack of research attention given to this issue, the possible ineffectiveness of the components of the technology applied, and possible ineffective application of the potentially effective technology. Suggestions for future research are discussed in terms of developing more effective educational and habilitative services for persons with profound multiple handicaps. In particular, we suggest research on a wider variety of behavioral teaching procedures, providing more comprehensive evaluations of the applications of procedures and developing treatment programs that do not focus solely on traditional skill acquisition.
