Transfer of negative occasion setting and conditioned inhibition across conditioned and unconditioned stimuli

The transfer of negative occasion setting and conditioned inhibition across conditioned stimuli (CSs) and unconditioned stimuli (USs) was examined in four experiments that used Pavlovian appetitive feature negative discrimination training procedures with rats. After training with simultaneous compounds (A+, XA-), X inhibited conditioned responding (CRs) elicited by other CSs and CRs supported by other appetitive USs that had not been involved in discrimination training. After training with serial compounds (A+, X----A-), X's power to set the occasion for nonresponding transferred across CSs and USs only if those events had also been involved in serial feature negative discrimination training. The results supported the suggestion that the acquisition of negative occasion setting involves the representation of individual events in a higher order memory system, separate from that involved in simple association, and that negative occasion setters act only on events that are represented in that system.     

Breast cancer representations in Canadian news media: a critical discourse analysis of meanings and the implications for identity

Despite the importance of critical media work, much is to be learned about breast cancer representations within media discourses and the implications for women’s identity construction. Building on research from Australia from a discursive perspective, this article used an eclectic approach to critical discourse analysis to explore the cultural construction of breast cancer in 25 detailed stories within Canada’s two national newspapers, The Globe and Mail and the National Post. Ten images accompanying stories and 17 advertisements/public service announcements were also analyzed to contextualize discourses and subject positions/identities within the stories. Analysis of this media affords the unique opportunity to explore taken for granted assumptions and prevailing meanings about breast cancer and the implications for subjectivity. Two primary discourses were identified: a discourse of biomedicine and a discourse of healthism. Subject positions identified included “breast cancer survivor,” “the good consumer,” and the “medical expert.” The psychological, social, political, and health promotion implications are discussed.     

I can’t steal from a coworker if I work from home: Conceptual and measurement-related issues associated with studying counterproductive work behavior in a telework setting

Teleworkers are an increasingly large proportion of the workforce. Despite the popularity of telework, organizations are concerned that telework offers employees more opportunity to engage in counterproductive work behavior (CWB). We argue that current CWB scales are inappropriate for the telework setting because this context affects the types of employee behavior that can (a) feasibly be enacted and (b) conceptually be considered as CWB. In this article, we develop a CWB scale suitable for the telework setting (i.e., the T-CWB scale) by addressing the errors of contamination (commission) and omission present in existing CWB scales vis-à-vis the telework setting. We end by outlining an agenda for future research on CWB in the telework setting.     

AIDS Educator Effectiveness as a Function of Sexual Orientation and HIV Status1

This study investigated the effectiveness of an AIDS educator as a function of his HIV status and sexual orientation. A 2 × 2 factorial design was employed where 136 heterosexual undergraduates viewed I of 4 videotapes of an AIDS educator who introduced himself as either HIV positive or negative and either heterosexual or homosexual. The videos were identical except for the introduction. Results revealed that all videos increased knowledge about AIDS. However, students' perceptions of risk increased only when they believed the educator was HIV positive and heterosexual. Intentions to get tested for HIV increased when they perceived the educator as HIV positive but declined when they thought she was HIV negative. Results suggest the sexual orientation and HIV status of educators can impact their effectiveness.     

The encoding of rate and talker information during phonetic perception

The acoustic structure of the speech signal is extremely variable due to a variety of contextual factors, including talker characteristics and speaking rate. To account for the listener’s ability to adjust to this variability, speech researchers have posited the existence of talker and rate normalization processes. The current study examined how the perceptual system encoded information about talker and speaking rate during phonetic perception. Experiments 1–3 examined this question, using a speeded classification paradigm developed by Garner (1974). The results of these experiments indicated that decisions about phonemic identity were affected by both talker and rate information: irrelevant variation in either dimension interfered with phonemic classification. While rate classification was also affected by phoneme variation, talker classification was not. Experiment 4 examined the impact of talker and rate variation on the voicing boundary under different blocking conditions. The results indicated that talker characteristics influenced the voicing boundary when talker variation occurred within a block of trials only under certain conditions. Rate variation, however, influenced the voicing boundary regardless of whether or not there was rate variation within a block of trials. The findings from these experiments indicate that phoneme and rate information are encoded in an integral manner during speech perception, while talker characteristics are encoded separately.     

Understanding Intentions to Exercise Following a Structured Exercise Program: An Attributional Perspective1

The present study examined the relationships among perceived outcome, causal attributions, affect, expected success, and intentions to exercise following a structured exercise program. Participants were 105 volunteers who had just completed a 12-week exercise program. Results indicated that perceived outcome over objective outcome (% attendance) was significantly more important for understanding the attribution process. Interesting interactions indicated that (a) individuals who made personally controllable attributions reported higher positive affect following perceived success, but lower positive affect following perceived failure than those who made personally uncontrollable attributions, and (b) individuals who made external attributions following perceived failure reported higher expected success than those who made internal attributions. Finally, both positive affect and expected success showed positive relationships with intention to exercise following the program. It was suggested that attribution theory may be beneficial to understanding continued exercise following structured exercise programs.     

Heritability of the Big Five Personality Dimensions and Their Facets: A Twin Study

ABSTRACT The genetic and environmental etiology of the five-factor model of personality as measured by the revised NEO Personality Inventory (NEO-PI-R) was assessed using 123 pairs of identical twins and 127 pairs of fraternal twins. Broad genetic influence on the five dimensions of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness was estimated at 41%, 53%, 61%, 41%, and 44%, respectively. The facet scales also showed substantial heritability, although for several facets the genetic influence was largely nonadditive. The influence of the environment was consistent across all dimensions and facets. Shared environmental influences accounted for a negligible proportion of the variance in most scales, whereas nonshared environmental influences accounted for the majority of the environmental variance in all scales.     

Talker continuity and the use of rate information during phonetic perception

Research has shown that speaking rate provides an important context for the perception of certain acoustic properties of speech. For example, syllable duration, which varies as a function of speaking rate, has been shown to influence the perception of voice onset time (VOT) for syllableinitial stop consonants. The purpose of the present experiments was to examine the influence of syllable duration when the initial portion of the syllable was produced by one talker and the remainder of the syllable was produced by a different talker. A short-duration and a long-duration /bi/-/pi/ continuum were synthesized with pitch and formant values appropriate to a female talker. When presented to listeners for identification, these stimuli demonstrated the typical effect of syllable duration on the voicing boundary: a shorter VOT boundary for the short stimuli than for the long stimuli. An /i/ vowel, synthesized with pitch and formant values appropriate to a male talker, was added to the end of each of the short tokens, producing a new hybrid continuum. Although the overall syllable duration of the hybrid stimuli equaled the original long stimuli, they produced a VOT boundary similar to that for the short stimuli. In a second experiment, two new /i/ vowels were synthesized. One had a pitch appropriate to a female talker with formant values appropriate to a male talker; the other had a pitch appropriate to a male talker and formants appropriate to a female talker. These vowels were used to create two new hybrid continua. In a third experiment, new hybrid continua were created by using more extreme male formant values. The results of both experiments demonstrated that the hybrid tokens with a change in pitch acted like the short stimuli, whereas the tokens with a change in formants acted like the long stimuli. A fourth experiment demonstrated that listeners could hear a change in talker with both sets of hybrid tokens. These results indicate that continuity of pitch but not formant structure appears to be the critical factor in the calculation of speaking rate within a syllable.     

Interpersonal evaluations,attitudes and attraction

The effect of interpersonal evaluations (e.g., judging a person's intelligence) on attraction toward an anonymous person (person-one) was investigated. The study was conducted to assess attraction in five interpersonal relationships in which evaluations commonly occur. Attraction of subjects toward person-one was greater for positive than for negative evaluations when person-one evaluated either the subjects or himself, when a second anonymous person evaluated person-one and the attitudes of person-one were similar to those of the subjects, and when the second person evaluated both person-one and the subjects. When person-one evaluated the subjects, attraction toward person-one was found predictable using the Byrne-Rhamey rule.
