Psychological stress,appraisal, emotion and Cardiovascular response in a public speaking task

Forty-three undergraduates (30 males, 13 females) prepared and performed a speech task (stressor) or a reading task (no-stressor control). Preparing to speak led to greater threat appraisal, negative emotion, and cardiovascular (CV) response than preparing to read aloud, particularly in speech anxious individuals. Delivering the speech, however, did not result in an increment in CV response over and above preparation. Although threat appraisals could not explain the effect of stress on CV response during task preparation, negative emotion accounted for over half of the effect. These data support the hypothesis that CV response in these studies is at least partially accounted for by psychological processes (stressor-specific anxiety and negative emotional response) and suggests that these processes may be best studied during a period of stressor anticipation.     

let your life speak: assessing the effectiveness of a program to explore meaning,purpose, and calling with college students

Typical career planning courses assist students with the self‐assessment process, career exploration, and decision making. Although this assistance is helpful, college students are increasingly concerned with issues of meaning and calling (P. Braun, 2005). The authors describe and test the effectiveness of the Let Your Life Speak course, a program to help students articulate their framework of life meaning and increase their sense of vocational calling. Results indicate an increase in sense of vocational calling, greater confidence in ability to achieve goals, and a deepened framework of life meaning. Moreover, 96% reported they would recommend the course to others.     

Human capital and objective indicators of career success: The mediating effects of cognitive ability and conscientiousness

The purpose of the current study is to examine the mediating processes through which human capital (e.g. education and work experience) contribute to objective indicators of career success (e.g. salaries and promotions). We are particularly interested in the ways in which cognitive ability and conscientiousness help explain the process through which human capital gets translated into performance effectiveness and tangible career attainments. Results from meta‐analytical structural equation modelling show that individuals' cognitive ability and conscientiousness mediate the effects of both education and organizational tenure on in‐role and extra‐role job performance. Ultimately, both in‐role and extra‐role job performance positively influence employees' salaries and promotions. The article concludes with implications for theory development and management practice.     

Touch attenuates infants’ physiological reactivity to stress

Animal studies demonstrate that maternal touch and contact regulate infant stress, and handling during periods of maternal deprivation attenuates the stress response. To measure the effects of touch on infant stress reactivity during simulated maternal deprivation, 53 dyads were tested in two paradigms: still‐face (SF) and still‐face with maternal touch (SF+T). Maternal and infant cortisol levels were sampled at baseline, reactivity, and recovery and mother’s and infant’s cardiac vagal tone were measured during the free play, still‐face, and reunion episodes of the procedure. Cortisol reactivity was higher among infants in the SF condition and while cortisol decreased at recovery for infants in the SF+T, it further increased for those in the SF. Vagal tone showed a greater suppression when SF was not accompanied by maternal touch. Touch synchrony during free play was associated with higher infant vagal tone, whereas touch myssynchrony – maternal tactile stimulation while the infant gaze averts – correlated with higher maternal and infant cortisol. In humans, as in mammals, the provision of touch during moments of maternal unavailability reduces infants’ physiological reactivity to stress.     

A note on a class of probability matching models

Probability matching is shown to be a property of a broad class of models of binary choice behavior.This note is based in part on a section of Feldman's doctoral dissertation submitted to the Graduate School of Industrial Administration, Carnegie Institute of Technology.     

Graduate Socialization in the Responsible Conduct of Research: A National Survey on the Research Ethics Training Experiences of Psychology Doctoral Students

Little is known about the mechanisms by which psychology graduate programs transmit responsible conduct of research (RCR) values. A national sample of 968 current students and recent graduates of mission-diverse doctoral psychology programs completed a Web-based survey on their research ethics challenges, perceptions of RCR mentoring and department climate, whether they were prepared to conduct research responsibly, and whether they believed psychology as a discipline promotes scientific integrity. Research experience, mentor RCR instruction and modeling, and department RCR policies predicted student RCR preparedness. Mentor RCR instruction, department RCR policies, and faculty modeling of RCR behaviors predicted confidence in the RCR integrity of the discipline. Implications for training are discussed.     

Repetition priming is not purely episodic in origin

The sufficiency of similarity among surface attributes of prime-target pairs to account for the pattern of facilitation obtained in the repetition priming paradigm was evaluated. In Experiment 1, morphological primes were singular, inflected case forms of Serbo-Croatian words and visual similarity of prime and target was manipulated by alternating the two alphabets in which the Serbo-Croatian language is written. Results indicated that the magnitude of facilitation in the alphabetically alternating condition was not reduced relative to the nonalternating condition (RUPI-RUPI vs. RUPI-RUPI) which suggested that visual similarity is not a necessary condition for facilitation in the present task. In Experiment 2, related pairs included (a) base forms with diminutives, a class of highly productive and semantically predictable derivations marked in Serbo-Croatian by suffixes and (b) base words with morphologically unrelated monomorphemic words whose orthographic pattern encompassed the target in initial position and a sequence of letters in final position that elsewhere functions as a diminutive suffix. No facilitation of word targets by orthographically similar but morphologically unrelated primes was observed although there was a tendency toward facilitation among structurally similar pseudowords. Collectively, the experiments suggested that structural similarity of prime and target is not a sufficient condition for facilitation in the repetition priming paradigm.     

Can you get a better deal elsewhere? The effects of psychological contract replicability on organizational commitment over time

Previous research on psychological contracts has focused on whether or not employees feel their employers have fulfilled the promises made to them. Instead, here we examine how perceptions of the external labor market, particularly about whether present psychological contracts could be replicated elsewhere, influence employees’ attachment to their current employers. In a longitudinal study of a diverse employee sample, we found perceptions that psychological contracts could not be replicated elsewhere accounted for a substantial amount of the variance in affective commitment (.38) and normative commitment (.29) and a smaller, but significant, amount of the variance in continuance commitment (.04). We also found significant moderating effects of age, work experience, and career stage on these relationships. The article concludes with implications for psychological contract theory, organizational commitment theory, and management practice.
