Concerning the psychophysical power law

It is fortunate that, despite our theorizings, most of our facts manage to stay stubbornly as they were. I am encouraged by that thought as it bears on a recent theoretical attempt by Treisman (1964) to do over the psychophysical law. I should like, more in explication than in rebuttal, to comment on three major points relating to the law in question.     

Variability of olfactory threshold and its role in assessment of aging

Olfactory thresholds of elderly persons (over 65 years) average one to two orders of magnitude higher than those of young adults (under 30 years). Past studies reveal enormous spreads (typically about three orders of magnitude) of individual thresholds within each age group and extensive overlap between the two groups—enough to question how typically decline in sensitivity characterizes the individual aged person. The present study shows that much of the observed overlap is misleading, because the brief threshold tests usually administered tend to exaggerate individual differences. A more representative assessment of an individual’s threshold (for 1-butanol) was achieved by averaging the thresholds from two to eight separate short tests, spread over 4 days. The spread of each group’s thresholds (12 young and 12 elderly subjects) narrowed strikingly as the number of tests averaged increased from one to four; further tests accomplished no additional narrowing of spread. Based on a single test, thresholds of young and elderly overlapped in the usual way; but based on four or more tests, thresholds of young and elderly overlapped little or not at all. The outcome (1) argues that decline in smell sensitivity seems to be, after all, a common feature of aging, and (2) sheds light on the sourcesof variability of sensory thresholds.     

Order of Presentation and Verbal Recruitment Strategy Effectiveness1

This study examined the relative effectiveness of three different verbal recruitment strategies (opinion conformity, other enhancement, and self-enhancement) presented in different orders. Sixty undergraduates viewed three recruiters, each of whom used a different recruitment strategy to describe a hypothetical graduate program. Participants rated their impressions of each recruiter and then decided which program to attend. Results indicated that presentation order significantly affected participants' ratings of the opinion conforming and self-enhancing recruiters. Furthermore, although participants generally preferred the other enhancing and opinion conforming recruiters, this preference did not translate into a decision to attend the other enhancer's university. Implications for both the recruitment and impression management literatures are discussed.     

TEACHING MEMORIZED SPELLING WITH A MICROCOMPUTER: TIME DELAY AND COMPUTER-ASSISTED INSTRUCTION

A computer-assisted instruction program was evaluated that used a constant time-delay procedure to teach 5 students 18 spelling words. In addition to delivering the instructional procedure, the program managed the presentation of training content based on individual student responding and collected instructional data on individual student performance. The procedure was effective at teaching 4 of the 5 students the words, and generalization occurred from the computer-delivered keyboard response format to a teacher-delivered hand-written response format. Maintenance data varied among the students. The study demonstrated the feasibility of using microcomputers to deliver time-delay instruction in special education classrooms and suggested several research questions related to specific features of microcomputer-delivered time-delay instruction.     

Integrating speech information across talkers,gender, and sensory modality: Female faces and male voices in the McGurk effect

Studies of the McGurk effect have shown that when discrepant phonetic information is delivered to the auditory and visual modalities, the information is combined into a new percept not originally presented to either modality. In typical experiments, the auditory and visual speech signals are generated by the same talker. The present experiment examined whether a discrepancy in the gender of the talker between the auditory and visual signals would influence the magnitude of the McGurk effect. A male talker’s voice was dubbed onto a videotape containing a female talker’s face, and vice versa. The gender-incongruent videotapes were compared with gender-congruent videotapes, in which a male talker’s voice was dubbed onto a male face and a female talker’s voice was dubbed onto a female face. Even though there was a clear incompatibility in talker characteristics between the auditory and visual signals on the incongruent videotapes, the resulting magnitude of the McGurk effectwas not significantly different for the incongruent as opposed to the congruent videotapes. The results indicate that the mechanism for integrating speech information from the auditory and the visual modalities is not disrupted by a gender incompatibility even when it is perceptually apparent. The findings are compatible with the theoretical notion that information about voice characteristics of the talker is extracted and used to normalize the speech signal at an early stage of phonetic processing, prior to the integration of the auditory and the visual information.     

The authoritarian dynamic and Brexit: Understanding the relationship between authoritarianism and wanting to leave the EU

Individual-level authoritarianism is prominent in explanations of preferences for Brexit. We contend that extant accounts have provided an incomplete theoretical and empirical understanding of this relationship. Drawing on the idea of the ‘authoritarian dynamic’, we show that perceptions of the economic/cultural threat of immigration have stronger effects on the pro-Brexit views of individuals with weak authoritarian predispositions (libertarians). At the same time, perceptions of normative threat, which pertain to concerns like loss of faith in or lack of consensus among established authorities, have a greater impact on the pro-Brexit views of individuals with high authoritarian predispositions (authoritarians). These conditional relationships, which have previously gone unacknowledged, are crucial to understanding which individuals are likely to respond to ‘increased threat’ with pro-Brexit attitudes. We demonstrate these relationships with pro-Brexit views using British Election Study longitudinal panel data. The results clarify the conditional impact of threats and authoritarian predispositions on attitudes.     

What communication skills do employers want? silicon valley recruiters respond

The purpose of this study was to analyze the satisfaction levels of Silicon Valley employers with the communication skills of newly hired college graduates. Employers reported that oral and written communication skills needed improvement in several areas, including the use of vocabulary and self‐expression. College graduates' skills are not always adequate to perform the tasks required on the job. Employers said students needed stronger writing skills; more training on professional uses of e‐mail; and additional education regarding self‐expression, impression management, and avoidance of slang.     

The Relationships of Teacher Ethnic Discrimination,Ethnic Identification,and Host National Identification to School Misconduct of Turkish and Moroccan Immigrant Adolescents in Belgium

We focus on school misconduct and how ethnic teacher discrimination, ethnic identification, and host national identification are associated with school misconduct of male and female immigrant adolescents. Additionally, we verify the moderating role of ethnic identification and host national identification. The results show that discrimination and host national identification are related with the school deviance of immigrant adolescents. The relationship between discrimination and school deviance differs for male and female adolescents. Ethnic identification and host national identification only moderate the relationship of ethnic teacher discrimination and school delinquency for girls who experienced ethnic teacher discrimination on a frequent basis.     

Authenticity: a mediator in the relationship between attachment style and affective functioning

Attachment has been show to exhibit a strong effect on emotional well-being throughout an individual’s lifetime. This study examined individuals’ authenticity as a potential mediating variable in the relationship between insecure attachment and affective functioning. Authenticity was examined from multiple perspectives to better define its role as a mediating variable. Results showed that avoidant attachment is a predictor of affective functioning, and that authenticity acts as a mediating variable in this relationship. Anxious attachment showed no direct relationship with affective functioning, yet evidence was found for an indirect pathway from anxious attachment through authenticity on affective functioning. The differing results by attachment style support Mikulincer, Shaver, and Pereg’s theory suggesting a two-part model of emotional response style, wherein individuals with avoidant attachment deactivate emotion and individuals with anxious attachment show hyper-activation when coping with emotion. The study examines the construct of authenticity and its importance in affective functioning. Implications for therapists working with clients are made that highlight the importance of authentic relationships in therapy and life.
