The Face-Space Typicality Paradox: Understanding the Face-Space Metaphor

Some recent accounts of human face processing use the idea of 'face space', considered to be a multi-dimensional space whose dimensions correspond to ways in which faces can vary. Within this space, 'typicality' is sometimes taken to reflect the proximity of a face to its local neighbours. Intuitions about the distribution of faces within the space may suggest that the majority of faces will be 'typical' in these terms. However, when typicality measures are taken, researchers very rarely find that faces cluster at the 'typical' end of the scale. In this short note we attempt to resolve this paradox and point out that reasoning about high dimensional distributions requires that some specific assumptions are made explicit.     

Differential gender effects of exposure to rap music on African American adolescents' acceptance of teen dating violence

The purpose of the present study was to assess the effects of exposure to nonviolent rap music on African American adolescents' perceptions of teen dating violence. African American male and female subjects were exposed to nonviolent rap videos (which contained images of women in sexually subordinate roles) or they saw no videos. They read a vignette that involved teen dating violence perpetrated by a male. The results indicated that there was a significant interaction between gender and video exposure. More specifically, acceptance of the use of violence did not vary as a function of exposure for male subjects. Conversely, female subjects who were exposed to the videos showed greater acceptance of the violence than females who were not exposed. Possible basis and implications for these findings are discussed.To whom reprint requests should be addressed at Department of Psychology, The University of North Carolina at Wilmington, 601 South College Road, Wilmington, NC 28403-3297.     

Single-Session Brief Counseling in a High School

Counseling designed to be time-limited is a valuable tool for counselors in school settings. Three approaches to brief counseling were investigated in this naturalistic study: problem-focused with task, problem-focused without task, and solution-focused with task. Quantitative and qualitative measures were used to explore aspects of single-session brief counseling. High school students made significant changes from the second-week follow-up to the sixth-week follow-up in alleviating their concerns and increasing the percentage of goal achieved. Students dramatically decreased the intensity of undesired feelings from before the counseling session through the second follow-up. Solution-focused counseling was as effective as the other two approaches, while taking less time.     

Smiles in face matching: Idiosyncratic information revealed through a smile improves unfamiliar face matching performance

Unfamiliar face matching is a surprisingly difficult task, yet we often rely on people's matching decisions in applied settings (e.g., border control). Most attempts to improve accuracy (including training and image manipulation) have had very limited success. In a series of studies, we demonstrate that using smiling rather than neutral pairs of images brings about significant improvements in face matching accuracy. This is true for both match and mismatch trials, implying that the information provided through a smile helps us detect images of the same identity as well as distinguishing between images of different identities. Study 1 compares matching performance when images in the face pair display either an open-mouth smile or a neutral expression. In Study 2, we add an intermediate level, closed-mouth smile, to identify the effect of teeth being exposed, and Study 3 explores face matching accuracy when only information about the lower part of the face is available. Results demonstrate that an open-mouth smile changes the face in an idiosyncratic way which aids face matching decisions. Such findings have practical implications for matching in the applied context where we typically use neutral images to represent ourselves in official documents.     

Children retain implicitly learned phonological sequences better than adults: a longitudinal study

Whereas adults often rely on explicit memory, children appear to excel in implicit memory, which plays an important role in the acquisition of various cognitive skills, such as those involved in language. The current study aimed to test the assertion of an age‐dependent shift in implicit versus explicit learning within a theoretical framework that explains the link between implicit sequence memory and word‐form acquisition, using the Hebb repetition paradigm. We conducted a one‐year, multiple‐session longitudinal study in which we presented auditory sequences of syllables, co‐presented with pictures of aliens, for immediate serial recall by a group of children (8–9 years) and by an adult group. The repetition of one Hebb sequence was explicitly announced, while the repetition of another Hebb sequence was unannounced and, therefore, implicit. Despite their overall inferior recall performance, the children showed better offline retention of the implicit Hebb sequence, compared with adults who showed a significant decrement across the delays. Adults had gained more explicit knowledge of the implicit sequence than children, but this could not explain the age‐dependent decline in the delayed memory for it. There was no significant age‐effect for delayed memory of the explicit Hebb sequence, with both age groups showing retention. Overall performance by adults was positively correlated with measures of post‐learning awareness. Performance by children was positively correlated with vocabulary knowledge. We conclude that children outperform adults in the retention over time of implicitly learned phonological sequences that will gradually consolidate into novel word‐forms. The findings are discussed in the light of maturational differences for implicit versus explicit memory systems that also play a role in language acquisition.

Understanding the Relationship between Language Ability and Plagiarism in Non-native English Speaking Business Students

Despite a continued focus exploring the factors related to plagiarism, the relationship between English language ability and plagiarism occurrences is not fully understood. Multiple studies involving student or faculty self-reporting of plagiarism have shown that students often claim English language ability is one of the main reasons why they commit plagiarism offences; however, little research has tested these claims in a rigorous, quantitative manner. This paper presents the findings of an analysis of data collected in a private, international university located in Vietnam, from non-native English speaking students studying business degrees. Analysis of the data builds on previous studies by showing that there are statistically significant differences in the English language abilities of students who have previously committed plagiarism offences, compared to students who have not, suggesting that programmes designed to improve the academic English skills of non-native English speaking students may help reduce incidences of plagiarism.
