Comparing implicit and explicit attitudes of gay,straight, and non-monosexual groups toward transmen and transwomen

Background: Transphobia studies have typically relied on self-report measures from heterosexual samples. However, there is evidence suggesting the need to use indirect measures and to explore transphobia among other populations. Aims: This study examined how explicit and implicit attitudes toward transwomen and transmen differ between people of different sexual orientations. Methods: Cisgender participants (N = 265) completed measures of explicit feelings toward transmen and transwomen, as well as Implicit Association Tests (IAT) for each group. Comparisons were made between 54 gay, 79 straight, and 132 non-monosexual (asexual, bisexual, pansexual) individuals. Results: An interaction was found between measurement type (explicit, implicit) and sexual orientation (straight, gay, non-monosexual). With regard to transmen, gay respondents’ explicit and implicit scores diverged such that they explicitly reported lower bias than their straight counterparts, but their Transmen-IAT showed an implicit preference for biological men over transmen. For attitudes toward transwomen, implicit measurement scores were consistently negative and did not differ by group. Gay participants also reported positive explicit attitudes toward transwomen, similar to non-monosexual people. Discussion: Overall, findings show that gay people tend to report positive attitudes toward transgender people explicitly, but tend to have implicit bias against both transmen and transwomen. Future studies need to explore the origins of these biases and how they relate to the complex interplay of sex, gender, and sexual orientation.     

Directing wayfinders with maps: the effects of gender, age, route complexity, and familiarity with the environment

The participants were 360 Canadian undergraduates. After receiving written scenarios involving a campus visitor seeking direction to a nearby destination (simple route) or a distant destination (complex route), they drew maps to that destination. The authors varied the visitor's gender, age, and familiarity with campus. They analyzed the content of the students' maps in terms of cardial indicators (compass grid, correct north-south orientation), landmarks, labeled buildings, directional arrows, and supplemental written directions. The men tended to provide more cartographically complete maps than the women, though there were no gender differences in use of landmarks or labeled buildings. The men were significantly more inclined than the women to take visitor characteristics into account, providing more complete maps to visitors navigating complex routes, to newcomers, and to older visitors who were unfamiliar with the campus. The men had more confidence that their maps would successfully lead visitors to their destinations. Route complexity led to greater use of landmarks, labeled buildings, and cardinal indicators. The participants' self-reported familiarity with campus had little effect on their direction giving, except for a greater use of labeled buildings in maps.     

Improvements in hippocampal-dependent learning and decremental attention in 5-HT(3) receptor overexpressing mice

The 5-HT3 receptor for serotonin is expressed within limbic structures and is known to modulate neurotransmitter release, suggesting that this receptor may influence learning and memory. Perturbations in serotonergic neurotransmission lead to changes in the ability to attend, learn, and remember. To examine the role of 5-HT3 receptors in learning, memory, and attention, 5-HT3 receptor overexpressing (5-HT3-OE) transgenic mice and their wild-type littermates (WT) were tested in Pavlovian contextual and cued fear conditioning, fear extinction, and latent inhibition (LI) paradigms. Prepulse inhibition (PPI) was assessed to reveal changes in sensorimotor gating. Additionally, anxious behaviors, shock sensitivity, and reactions to novel stimuli were evaluated. 5-HT3-OE mice displayed enhanced contextual conditioning, whereas cued conditioning remained the same as that of WT mice. 5-HT3-OE mice did not differ from WT in extinction rates to either the context or cue. LI was enhanced for 5-HT3-OE mice compared to WT. PPI remained unchanged. No differences in sensitivity to footshock or startle were found. However, 5-HT3-OE mice demonstrated heightened exploratory behavior in response to novel environmental stimuli and decreased anxiety as measured in the elevated plus-maze. Results indicate that overexpression of the 5-HT3 receptor in mouse forebrain results in enhanced hippocampal-dependent learning and attention. Enhanced inspective behavior in response to novelty may contribute to the observed improvements in learning, memory, and attention due to 5-HT3 receptor overexpression.     

Perceived risk of work-related injury and intentions to change employment

A survey of 263 employed men and women examined the effect of length of employment, perceived ability to find a better job, positive job features (pay, job security, and intrinsic interest), and perceived risk of occupational injury on intentions to stay with or leave one's current employer. Perceived risk of occupational injury significantly predicted one's belief that the person would not stay with the current employer. Perceived inability to find alternative employment lessened the desirability of leaving the current employer. Desire to leave was lower when a job was rated highly for pay, security, and intrinsic interest. Length of employment, as a measure of job commitment, was not a factor.     

Voices outside the camp: Some significant nonpastoral books in 1979–80

A review article of recent books in disciplines related to pastoral care which may increase the effectiveness of the pastor's care and counseling ministries. Books selected challenge prevailing assumptions, offer new ways to perceive the pastoral task, and provide new and significant information. Books are reviewed from personality and psychotherapy, family history, theory and therapy, studies of violence and victimization, psychology and theology, and general ministry theory.Dr. Hunter is Associate Professor of Pastoral Theology and Book Review Editor ofPastoral Psychology.

Selective Synaptic Plasticity within the Cerebellar Cortex Following Complex Motor Skill Learning

Complex motor skill learning, but not mere motor activity, leads to an increase in synapse number within the cerebellar cortex. The present experiment used quantitative electron microscopy to determine which synapse types were altered in number. Adult female rats were allocated to either an acrobatic condition (AC), a voluntary exercise condition (VX), or an inactive condition (IC). AC animals were trained to traverse an elevated obstacle course requiring substantial motor coordination to complete. VX animals were housed with unlimited access to running wheels and IC animals received no motor training but were handled briefly each day. Results showed the AC animals to have significantly more parallel fiber to Purkinje cell synapses than both the VX and IC animals. No other synapse type was significantly altered. Thus, the learning-dependent increase in synapse number observed within the cerebellar cortex is accomplished primarily through the addition of parallel fiber synapses.
