Beidler’s taste equation: A correction

Beidler derived an equation relating the magnitude of neural response to a gustatory stimulus with the concentration of that stimulus. In the derivation, he assumed the amount of stimulating substance removed from the solution by the receptors was small enough not to change the stimulus concentration appreciably. An equation without this assumption is derived, and is evaluated in the light of existing data. The hypothesis for a dissociation reaction in taste inception under some circumstances is given support.     

Existentialism,Self Theory and the Existential Self

Self theory is reductionistic: it brackets off “real” reality and leaves it in metaphysical realms. Existentialism views both subjective and external reality as contained in existence. Rogers' theory is deterministic to the extent that it is built on causal constructs. The non-deterministic, holistic, and teleological assumptions of the existentialists may help strengthen self theories. For example the term existential self would combine self-as-doer and self-as-object, making such constructs as self-concept, self structure, individual, and organism unnecessary. The individual's experience or perception would not have to be caused by a self-definition, but would be for the purpose of something, i.e., his intentions or goals.     

Study Preregistration: An Evaluation of a Method for Transparent Reporting

Study preregistration promotes transparency in scientific research by making a clear distinction between a priori and post hoc procedures or analyses. Management and applied psychology have not embraced preregistration in the way other closely related social science fields have. There may be concerns that preregistration does not add value and prevents exploratory data analyses. Using a mixed-method approach, in Study 1, we compared published preregistered samples against published non-preregistered samples. We found that preregistration effectively facilitated more transparent reporting based on criteria (i.e., confirmed hypotheses and a priori analysis plans). Moreover, consistent with concerns that the published literature contains elevated type I error rates, preregistered samples had fewer statistically significant results (48%) than non-preregistered samples (66%). To learn about the perceived advantages, disadvantages, and misconceptions of study preregistration, in Study 2, we surveyed authors of preregistered studies and authors who had never preregistered a study. Participants in both samples had positive inclinations towards preregistration yet expressed concerns about the process. We conclude with a review of best practices for management and applied psychology stakeholders.

     

Knowing full well: the normativity of beliefs as performances

Belief is considered a kind of performance, which attains one level of success if it is true (or accurate), a second level if competent (or adroit), and a third if true because competent (or apt). Knowledge on one level (the animal level) is apt belief. The epistemic normativity constitutive of such knowledge is thus a kind of performance normativity. A problem is posed for this account by the fact that suspension of belief seems to fall under the same sort of epistemic normativity as does belief itself, yet to suspend is of course precisely not to perform, certainly not with the aim of truth. The paper takes up this problem, and proposes a solution that distinguishes levels of performance norrmativity, including a first order where execution competence is in play, and a second order where the performer must assess the risks attendant on issuing a first-order performance. This imports a level of reflective knowledge that ascends above the animal level.

Can Virtual Reality Increase the Realism of Role Plays Used to Teach College Women Sexual Coercion and Rape-Resistance Skills?

The present study evaluated whether virtual reality (VR) can enhance the realism of role plays designed to help college women resist sexual attacks. Sixty-two female undergraduate students were randomly assigned to either the Role Play (RP) or Virtual Role Play (VRP) conditions, which were differentiated only by the use of VR technology in the VRP condition. A multimethod assessment strategy was used to evaluate the effects of VR on the experienced realism of sexually threatening role plays. Realism was assessed by participant self-reports of negative affect and perceptions of realism, direct observation of participants' verbal displays of negative affect during the role plays, and measurements of participant heart rate during the role plays. Results indicated that VR can indeed heighten the realism of sexually threatening role plays. Discussion focuses on issues regarding the use of VR-enhanced role plays for helping college women resist sexual attacks.     

Unspoken Skills and Tactics: Essentials for Immigrant Professionals in Integration to Workplace Culture

Skilled workers and their dependents are the largest group of economic immigrants in Canada, and their labour market integration is critical for immigrant well-being as well as host country economic productivity. However, immigrant professionals face significant barriers to workplace integration, including unfamiliarity with workplace norms and practices. Drawing on constructivist grounded theory, this qualitative study examined challenges associated with socio-cultural workplace interactions and etiquettes among immigrant professionals in Alberta, Canada, as well as strategies to facilitate workplace integration. Data was collected through semi-structured interviews with 32 immigrant professionals and 30 immigrant service providers and employers. Participants described challenges related to workplace communication and interactions, adaptation to new workplace cultures, recognition of qualifications and experience, and professional outcomes. They identified general professional values, skills, and capacities, and communication and relationships perceived as essential for workplace integration. Strategies for supporting workplace integration included continuing learning and education, training on cultural diversity and workplace skills, professional field experience, and professional mentorship. These findings have implications for practice and policies facilitating the workplace integration of immigrant professionals in Canada, including training and mentorship approaches.     

Effects of preweaning predatory or consummatory experience and litter size on cricket predation in northern grasshopper mice (Onychomys leucogaster)

Preweaning exposure to cricket killing and consumption, but not consumption alone, facilitated postweaning cricket predation. This facilitatory effect did not result from kill-sharing by the parents or from food competition among the offspring. The results were strongly influenced by litter size. Small litters (N = 3–4) were strongly facilitated in all measures of predatory behavior when compared to litters of five to six mice. Since smaller litters of this species also show much higher levels of play behavior, it is suggested that play frequency may strongly facilitate later predatory behavior.     

Partner aggression and children's externalizing problems: maternal and partner warmth as protective factors.

This research examined maternal and partner warmth as moderators of the relation between men's intimate partner aggression and children's externalizing problems. Participants were 157 mothers and their children (ages 7-9 years). Results indicate that maternal and partner warmth each moderated the relation between men's intimate partner aggression and children's externalizing problems. Partner-to-mother aggression was positively associated with child reports of externalizing problems at lower, but not higher, levels of maternal warmth. Similarly, partner-to-mother aggression was positively associated with mother reports of girls', but not boys', externalizing problems at lower, but not higher, levels of maternal warmth. On the other hand, the moderating effect of partner warmth was in the opposite direction and was found only with child-reported externalizing problems. Increased levels of partner-to-mother aggression related positively to child-reported externalizing problems when partners were higher, but not lower, in warmth.
