College students’ prejudicial biases against instructors who smoke cigarettes

In an investigation of students’ prejudicial biases against instructors who smoke, 61 female and 16 male undergraduates watched and listened to a 20-min lecture about parasomnias, completed a survey asking for instructor evaluation ratings and ratings of perceived learning, and completed a lecture-retention test with multiple-choice questions to assess actual learning. In a between-subjects design, the lecture was given by either a man or woman, who was portrayed as a smoker or nonsmoker. The instructors’ sex and smoking status did not affect the students’ perceived or actual learning (all p’s > .05). However, a significant interaction on the instructor evaluation ratings revealed that students rated the female instructors equivalently (p = .78), but rated the smoker male instructor significantly lower than the nonsmoker male instructor (p = .01). These findings suggest that students hold prejudicial biases against male instructors who smoke, but that these biases do not affect student learning.     

The Galileo bias: a naive conceptual belief that influences people's perceptions and performance in a ball-dropping task

This research introduces a new naive physics belief, the Galileo bias, whereby people ignore air resistance and falsely believe that all objects fall at the same rate. Survey results revealed that this bias is held by many and is surprisingly strongest for those with formal physics instruction. In 2 experiments, 98 participants dropped ball pairs varying in volume and/or mass from a height of 10 m, with the goal of both balls hitting the ground simultaneously. The majority of participants in both experiments adopted a single strategy consistent with the Galileo bias, showing no improvement across trials. Yet, for participants reporting intentions of dropping both balls at the same time, the differences between release points were significantly greater than 0 ms. These findings support separate but interacting cognition and perception-action systems.     

Searching for interference effects in learning new face-name associations

In three experiments we attempted to increase interference using experimental manipulations in a face-name learning paradigm. All experiments included young and older adult participants because ageing is associated with increases in both susceptibility to interference and difficulty in learning face-name associations. None of the experiments produced interference for either age group: The inclusion of confusable (i.e., ambiguous) names and occupations, having to learn an additional piece of information in association with each face, and requiring participants to guess when uncertain all failed to negatively impact name learning. Interference does not appear to be the critical mechanism underlying the difficulty of learning proper names, and it cannot account for older adults' disproportionate decline in name-learning ability.     

Global Banking and Financial Services to Immigrants in Canada and the US

It is important to consider how financial institutions are adjusting their operational strategies because of the changing dynamics of financial resource and population flows. This paper compares the ways in which globally prominent banks provide financial services to immigrants in Canada and the US and addresses the following two research questions: (1) How has HSBC reacted strategically and operationally to people–money comovements involving immigrants, in which HSBC has ethnic assets, in the US and Canada? (2) What are the similarities and differences in HSBC’s strategic choices in entering or expanding in the San Francisco and Vancouver areas, and what explains such differences?     

Searching for interference effects in learning new face–name associations

In three experiments we attempted to increase interference using experimental manipulations in a face–name learning paradigm.

None of the experiments produced interference for either age group: The inclusion of confusable (i.e., ambiguous) names and occupations, having to learn an additional piece of information in association with each face, and requiring participants to guess when uncertain all failed to negatively impact name learning.

Social–emotional competencies make the grade: Predicting academic success in early adolescence

The goals of this study were to longitudinally examine the association between social and emotional competence (SEC) and academic achievement in early adolescence, exploring the moderating role of gender in this relation. Using a short-term longitudinal design, self- and teacher-reported indicators of SEC were used to predict early adolescents' (N = 461, Mean age = 12.02 years, SD = 0.41, 47% female) achievement in math and reading on a standardized achievement test in grade 7. As hypothesized, teacher-reported SEC in sixth grade significantly predicted higher scores in math and reading on the standardized test in seventh grade. A significant interaction between self-reported SEC and gender in predicting reading scores indicated that SEC was a significant positive predictor for reading outcomes in boys only. Self-reported SEC was not significantly related to math achievement. Results are discussed in line with the literature and practical implications of the findings are discussed.     

Relations among peer acceptance,inhibitory control,and math achievement in early adolescence

This study examined relations among peer acceptance, inhibitory control, and math achievement in ninety-nine 4th and 5th grade early adolescents. Teachers rated students on peer acceptance and students completed a computerized executive function task assessing inhibitory control. Math achievement was assessed via end of year math grades. Results indicated that both inhibitory control and peer acceptance were positively and significantly related to math achievement. In addition, peer acceptance significantly mediated the relationship between inhibitory control and math grades when all three variables were entered simultaneously in a linear regression model. These results suggest that peer acceptance is an important indicator of social functioning and plays a significant part in academic success in the classroom. Results also suggest that indicators of social functioning – such as peer acceptance – need to be included in addition to cognitive functioning, when examining academic achievement in early adolescence.     

Motion by nearby players biases perception but not action in judgments of baseball destination

In this research, the influence of irrelevant reference frames on estimates of ball destination was examined. In 3 experiments, confederate base runners and fielders served as distractor stimuli while balls were rolled from home plate to random locations along a barrier hidden under an elevated tarp between first and second base. Stationary participants estimated the position that the ball would exit from under the tarp if there were no barrier, whereas running participants ran along the back edge of the barrier and touched the top of the tarp above where they believed the ball would exit. Estimates of ball destination were significantly biased in the direction opposite to the confederates' motion for stationary participants, but were accurate for running participants. These findings are consistent with other perception-action dissociations, and show that relative motion effects can occur in a naturalistic setting.     

Independence and separability of volume and mass in the size-weight illusion

Numerous size-weight illusion models were classified in the present article according to general recognition theory (Ashby & Townsend, 1986), wherein the illusion results from a lack of perceptual separability, perceptual independence, decisional separability, or a combination of the three. These options were tested in two experiments in which a feature-complete factorial design and multidimensional signal detection analysis were used (Kadlec & Townsend, 1992a, 1992b). With haptic touch alone, the illusion was associated with a lack of perceptual and decisional separability. When the participant viewed the stimulus in his or her hand, the illusion was associated only with a lack of decisional separability. Visual input appeared to improve the discrimination of mass, leaving only the response bias due to expectation.
