Perceptions of the organizational context and psychological contract breach: Assessing competing perspectives

This study examines how employees’ perceptions of specific features of the organizational context—organizational politics and procedural justice—are related to their evaluations of psychological contract breach and subsequent attitudes and behaviors. Across three studies, we examined the appropriateness of four models for describing relationships among the focal constructs. Results of these studies support (a) an environmental responsiveness model in which psychological contract breach mediates the effects of politics and justice on employee outcomes, and (b) a general fairness evaluation model where politics, justice, and psychological contract breach serve as indicators of a higher order factor that predicts employee attitudes and behavior. Implications and directions for future research are presented.     

Factors influencing therapist selection among gays,lesbians and bisexuals

For this study 609 gay, lesbian and bisexual individuals were surveyed with respect to openness about sexual orientation and preference for a therapist with a particular sexual orientation. Other factors considered important in selecting a therapist such as licensure, referral source, gender, cost and specialty were also examined. Data for this study was collected using two different methods. In the first method, data was collected from respondents subscribing to internet listervers serving gay, lesbian and bisexual subscribers. In the second, more traditional method, surveys were distributed by mail or hand delivered to various organizations serving gay, lesbian, and bisexual communities in two southwestern states. Findings suggest that significantly more lesbians than gay men and bisexuals in the e-mail sample prefer a therapist of the same sexual orientation. No significant relationships were found between degree of openness and importance of the therapist's sexual orientation. Other factors related to therapist preference were explored, and results are discussed.     

The “r” that psychology forgot: Research on writing processes

Development of theory and methodology related to the psychology of reading and mathematical problem solving has far outpaced progress in the realm of the psychology of writing. However, recently published theories may serve to link written language production research with mainstream psychology, and new computer-based methodologies may help to make conducting research in writing more tractable. This paper describes several new initiatives for studying writing within a framework based on recent theories of working memory.     

Visual field differences for clockwise and counterclockwise mental rotation

Geometric line drawings were presented to normal subjects in the left visual field (LVF) or right visual field (RVF) at various degrees of rotation from a centrally presented vertical standard. The task of the subject was to indicate with a reaction time (RT) response whether the laterally presented stimulus could be rotated into the vertical standard or if it was a rotated mirror image of the standard. In Study 1, an overall right hemisphere superiority was found for RT and accuracy on match trials. Most interestingly, interactions between Visual Field and Rotation Angle for the match accuracy data and between Visual Field and Direction of Rotation (clockwise or counterclockwise) for the match RT slopes were found. These interactions suggested that clockwise rotations were more readily performed in the LVF and counterclockwise rotations in the RVF, consistent with other literature for mental rotation. The purpose of Study 2 was to replicate this finding of visual field differences for rotation direction using a design in which direction and degree of rotation were varied orthogonally. No main effect of Visual Field was found. However, significant interactions between Visual Field and Rotation Angle were found for both RT and accuracy, confirming the presence of visual field differences for rotation direction in a new sample of subjects. These differences were discussed in terms of the possibly greater relevance of medially directed stimuli and a possible hemispheric bias for rotation direction, and in terms of interhemispheric transmission factors.     

Radial arm maze performance of mice: acquisition and atropine effects

CD-1 mice were successfully trained in a six-arm radial maze in which half of the arms were baited, a procedure which had been used to differentiate between reference and working memory. Stable performance was achieved following eight daily training sessions, as measured by decreasing running time and number of errors. This finding strengthens the foraging hypothesis as a basis for the performance of rodents in the radial maze. Acute subcutaneous administration of the cholinergic antagonist atropine sulfate (1-6 mg/kg) to trained mice produced dose-related increases in running time and working memory errors, with a slight decrease in reference memory errors. This is in agreement with other studies on the role of the cholinergic system in memory processes. The peripheral cholinergic blocker, atropine methyl nitrate (4 mg/kg), somewhat increased running time without decreasing performance accuracy. In contrast to the prolonged pharmacological and physiological effects of atropine, behavioral decrements disappeared within 3 hr. It is concluded that mice trained in the radial arm maze may be used for screening of the effects of drugs on cognitive function.     

The role of phonology in the activation of word meanings during reading: evidence from proofreading and eye movements.

Six experiments explored the role of phonology in the activation of word meanings when words were embedded in meaningful texts. Specifically, the studies examined whether participants detected the substitution of a homophone mate for a contextually appropriate homophone. The frequency of the incorrect homophone, the frequency of the correct homophone, and the predictability of the correct homophone were manipulated. Also, the impact of reading skill was examined. When correct homophones were not predictable and participants had a range of reading abilities, the evidence indicated that phonology plays a role in activating the meanings of low-frequency words only. When the performance of good and poor readers was examined separately, the evidence indicated that good readers primarily activate the meanings of words using the direct route, whereas poor readers primarily activate the meanings of words using the phonological route.     

The effects of stimulus dimensionality on the rate of gain of information

Hick's paradigm as extended to an absolute judgment task by Doherty was used to study the effects of dimensionality on the rate of stimulus identification in two experiments. Two undimensional conditions, size and brightness, and two bidimensional conditions, size-brightness redundant and size-brightness non-redundant, were employed. The significant linear components of the regression of choice reaction time on transmitted information for the undimensional and bidimensional stimuli supported and extended Hick's law. The finding of nearly identical slopes for the two undimensional and redundant bidimensional condition regression lines suggests a stage of processing which has a constant capacity in bits/s and which is independent of stimulus dimensionality. An increase in slope for the non-redundant condition is attributed to a difference in response requirements.
