Do they ‘look’ different(ly)? Dynamic face recognition in Malaysians: Chinese,Malays and Indians compared

Previous cross-cultural eye-tracking studies examining face recognition discovered differences in the eye movement strategies that observers employ when perceiving faces. However, it is unclear (1) the degree to which this effect is fundamentally related to culture and (2) to what extent facial physiognomy can account for the differences in looking strategies when scanning own- and other-race faces. In the current study, Malay, Chinese and Indian young adults who live in the same multiracial country performed a modified yes/no recognition task. Participants' recognition accuracy and eye movements were recorded while viewing muted face videos of own- and other-race individuals. Behavioural results revealed a clear own-race advantage in recognition memory, and eye-tracking results showed that the three ethnic race groups adopted dissimilar fixation patterns when perceiving faces. Chinese participants preferentially attended more to the eyes than Indian participants did, while Indian participants made more and longer fixations on the nose than Malay participants did. In addition, we detected statistically significant, though subtle, differences in fixation patterns between the faces of the three races. These findings suggest that the racial differences in face-scanning patterns may be attributed both to culture and to variations in facial physiognomy between races.     

Predictor variables for a 100-km race time in male ultra-marathoners

In 169 male 100-km ultra-marathoners, the variables of anthropometry, training, and prerace experience, in order to predict race time, were investigated. In the bivariate analysis, age (r = .24), body mass (r = .20), Body Mass Index (r = .29), circumference of upper arm (r = .26), percent body fat (r = .45), mean weekly running hours (r = -.21), mean weekly running kilometers (r = -.43), mean speed in training (r=-.56), personal best time in a marathon (r = .65), the number of finished 100-km ultra-runs (r = .24), and the personal best time in a 100-km ultra-run (r = .72) were associated with race time. Stepwise multiple regression showed that training speed (p < .0001), mean weekly running kilometers (p < .0001), and age (p < .0001) were the best correlations for a 100-km race time. Performance may be predicted (n=169, r2 = .43) by the following equation: 100-km race time (min) = 1085.60 - 36.26 x (training speed, km/hr.) - 1.43 x (training volume, km/wk.) + 2.50 x (age, yr.). Overall, intensity of training might be more important for a successful outcome in a 100-km race than anthropometric attributes. Motivation to train intensely for such an ultra-endurance run should be explored as this might be the key for a successful finish.     

Speed during training and anthropometric measures in relation to race performance by male and female open-water ultra-endurance swimmers

The relationship of anthropometric and training characteristics with race time were investigated in 39 male and 24 female open-water ultra-endurance swimmers in a 26.4 km open-water ultra-swim, using bi- and multivariate analyses. For the men, body height, Body Mass Index, length of arm, and swimming speed during training were related to race time in the bivariate analysis. For the women, swimming speed during training was associated with performance in the bivariate analysis. In the multivariate analysis for the men, Body Mass Index and swimming speed during training were related to race time.     

Black-White Differences in Nonverbal Behavior in an Interview Setting

The majority of systematic research on nonverbal behavior has used white college students as subjects. The present investigation examined both white and black subjects'nonverbal behavior and also independently varied the race of the person with whom the subject interacted. The experimental setting was an actual employment interview. Twenty black and 20 white female undergraduates were individually interviewed by either a black or white male interviewer. White subjects tended to maintain more visual interaction with interviewers of both races than did black subjects. Moreover, black interviewers were visually interacted with less, and given shorter glances. Racial, in contrast to nonracial, questions elicited longer glances; and subjects hesitated longer before answering them.     

Impact of length of unemployment and age on jobless men and women: a comparative analysis

The study examined differences in job search intensity, as well as attitudes toward unemployment and related responses among a sample of 559 jobless Israelis. Groups of participants were distinguished according to sex, age, and length of unemployment. The findings revealed that job search intensity, psychological stress, and work centrality were highest among participants who had been unemployed for 2 to 3 months, and gradually declined for longer periods of unemployment. Moreover, middle‐aged participants spent more hours per week searching for jobs and mentioned fewer advantages of unemployment than did the younger groups. Furthermore, women reported a sharper decline in health as a result of unemployment, as well as lower levels of work centrality.     

Physical training and personality factors as predictors of marathon time and training injury

On the basis of surveys completed by 105 male participants in a popular marathon, a multiple regression analysis was conducted to identify the variables contributing significantly to the prediction of final time. Overall prediction was successful, with R = .896, and training pace was the most important factor in the equation, speedier workouts being associated with faster marathon times. Final time was also related positively to best 10-km race time in the previous 12 mo. and repression-sensitization (faster runners being more sensitized), and negatively to maximum number of training miles in a single week, number of previous marathons completed, and number of days of training lost through illness or injury. Contrary to expectations, locus of control was not related to final time. Only 27% of the runners had lost training time through injury, but a discriminant analysis showed that, compared to those who had avoided this problem, the injured were younger, rested less, ran less in the week prior to the marathon, ran a slightly longer long run but ran it earlier before the race, and ran fewer runs of 20 miles or more. It is suggested that researchers should study the repression-sensitization variable and investigate injury in runners preparing for a marathon.     

Inter‐racial contact and the own‐race bias for face recognition in South Africa and England

Own‐race bias, where people are more accurate recognizing faces of people from their own race than other races, can lead to misidentification and, in some cases, innocent people being convicted. This bias was explored in South Africa and England, using Black and White participants. People were shown several photographs of Black and White faces and were later asked if they had seen these faces (and several fillers). In addition, participants were given a questionnaire about inter‐racial contact. Cross‐race identification accuracy for Black participants was positively correlated with self‐reported inter‐racial contact. The confidence–accuracy relationship was strongest when making own‐race judgements. Copyright © 2003 John Wiley & Sons, Ltd.     

Memory in posttraumatic stress disorder: properties of voluntary and involuntary, traumatic and nontraumatic autobiographical memories in people with and without posttraumatic stress disorder symptoms

One hundred fifteen undergraduates rated 15 word-cued memories and their 3 most negatively stressful, 3 most positive, and 7 most important events and completed tests of personality and depression. Eighty-nine also recorded involuntary memories online for 1 week. In the first 3-way comparisons needed to test existing theories, comparisons were made of memories of stressful events versus control events and involuntary versus voluntary memories in people high versus low in posttraumatic stress disorder (PTSD) symptom severity. For all participants, stressful memories had more emotional intensity, more frequent voluntary and involuntary retrieval, but not more fragmentation. For all memories, participants with greater PTSD symptom severity showed the same differences. Involuntary memories had more emotional intensity and less centrality to the life story than voluntary memories. Meeting the diagnostic criteria for traumatic events had no effect, but the emotional responses to events did. In 533 undergraduates, correlations among measures were replicated and the Negative Intensity factor of the Affect Intensity Measure correlated with PTSD symptom severity. No special trauma mechanisms were needed to account for the results, which are summarized by the autobiographical memory theory of PTSD.     

Explanatory style and gambling: How pessimists respond to losing wagers

Fifty-three patrons of a harness racing track completed two measures of explanatory style prior to an afternoon's races. One measure assessed general explanatory style, using bad events taken from the Attributional Style Questionnaire, and the other measure assessed betting-specific explanatory style, using bad events specific to harness race betting. Subjects then kept a diary during the first eight races. After each race, they reported how much they had bet, whether they had won or lost, the major cause of the outcome, their confidence about winning future bets, and whether they were ruminating about past or future races. Explanatory style assessed in both ways had similar correlates. Explanatory style predicted the specific attributions made by subjects for losses. Pessimistic explanatory style (internal + stable + global attributions) predicted rumination following a lost bet, but it was unrelated to expressed confidence. Rumination after a loss was in turn associated with larger wagers on subsequent races and a tendency toward less successful wagers. These results clarify one way in which pessimistic explanatory style results in helplessness, and suggest a path by which problematic gambling may develop.     

Self-Esteem Among Young Adults: Differences and Similarities Based on Gender, Race, and Cohort (1990–2012)

The major purpose of this study was to examine the joint effects of race and gender on the self-esteem of young adults. Data came from a large sample of undergraduate students (N?=?7,552; 2,785 men and 4,767 women) enrolled at a Midwestern U.S. University over the period 1990–2012. Consistent with prior research, we found that men had higher self-esteem than women and that Blacks had higher self-esteem than Whites, Hispanics, and Asians. The analyses, however, revealed that the gender differences in self-esteem were not found among Blacks and that the higher self-esteem of Blacks relative to other races was greater among women than among men. The effects of race and gender did not change controlling for social class and other demographic variables, did not differ across domains of self-esteem, and were not affected by period of time. This study deepens our knowledge of social group differences in self-esteem, providing evidence that the higher self-esteem of men (relative to women) and of Blacks (relative to other races) persisted across the past two decades.     

Strategic aspects of reaction time in world-class sprinters

Simple reaction time (RT) is defined as the time duration following the initiation of a stimulus and the resultant first observable response. For sprinters, RT to a start should be especially important, as this may determine the outcome of the race. The aim of this study was to investigate whether sprinters (from 100 to 400 m) try to anticipate the starter's shot within the false start limit (100 msec. after the shot). Subjects were male sprinters who have reached the final of a sprint event in World Championships or Olympic Games. Analysis indicated that RT to the starting shot plays a role in the eight finalists' strategy throughout an event (requiring a total of four sprints). Four characteristics of the strategic aspects of RT were found: (i) Increased mean RT from short dashes to longer sprints (from 60 m indoor, to 100 m, 200 m, and 400 m); (ii) RT values increase as a function of race length, i.e., the RT of the first sprinter in a 4 x 100-m relay is no different from that of a 400-m sprinter; conversely, RT of the first relay sprinter in a 4 x 400-m, i.e., a 1600-m race, is significantly different from RT in a 400-m race; (iii) RT decreases from the heats to the final for the eight finalists; (iv) Decreased RT is not observable in less experienced sprinters through the qualifying rounds (junior 18- or 19-yr.-old sprinters, taking part in their own World Championships). RT must be considered a skill dependent upon experience and learning and is associated with race length. The shorter the race, the more important the RT is for the final performance (both time and place), so sprinters try to decrease RT in the shorter dashes (60 m and 100 m). In the longer sprint races (4 x 400-m relay) they are content to respond to the shot. Intermediate distance races elicit intermediate values of RT. Such behavior could be explained by the importance of RT throughout the factors which influence sprint performance and by reference to allocation of concentration resources and expenditure.     

Pace alteration and estimation of time intervals

This experiment examined the effects on participants' estimates of interval duration of altering the pace of auditory stimuli contained within "filled" intervals. Because most previous studies on the filled interval effect have utilized visual displays, auditory stimuli were used to assess whether the effect would be present. In addition, previous studies compared two intervals, one of which was filled and the other unfilled. In the present study, both intervals were filled with tones at one of three rates (or "paces"): slow, medium, or fast. 25 participants (20 women) ages 18 to 29 years (M = 20.4, SD = 2.3) were recruited from psychology courses and programs. Participants first heard a "training" interval filled with tones at one of the three paces and then attempted to reproduce the duration of that training interval in the "test" interval. The pace of stimuli in each pair of training and test intervals was varied so participants received all possible combinations of paces of auditory stimuli during the training and test trial sets. Analysis showed that, when training pace was fast and test pace was medium or slow, participants' estimates were longer than the actual test interval durations. Conversely, when training pace was slow and test pace was medium or fast, participants' estimates were shorter than actual test interval durations. In addition, when judging shorter intervals, participants estimated more time had passed than actually had, while they estimated that less time had passed than actually had for longer intervals, thus providing support for Vierordt's law.     

Differential emotion attribution to neutral faces of own and other races

Past research has demonstrated differential recognition of emotion on faces of different races. This paper reports the first study to explore differential emotion attribution to neutral faces of different races. Chinese and Caucasian adults viewed a series of Chinese and Caucasian neutral faces and judged their outward facial expression: neutral, positive, or negative. The results showed that both Chinese and Caucasian viewers perceived more Chinese faces than Caucasian faces as neutral. Nevertheless, Chinese viewers attributed positive emotion to Caucasian faces more than to Chinese faces, whereas Caucasian viewers attributed negative emotion to Caucasian faces more than to Chinese faces. Moreover, Chinese viewers attributed negative and neutral emotion to the faces of both races without significant difference in frequency, whereas Caucasian viewers mostly attributed neutral emotion to the faces. These differences between Chinese and Caucasian viewers may be due to differential visual experience, culture, racial stereotype, or expectation of the experiment. We also used eye tracking among the Chinese participants to explore the relationship between face-processing strategy and emotion attribution to neutral faces. The results showed that the interaction between emotion attribution and face race was significant on face-processing strategy, such as fixation proportion on eyes and saccade amplitude. Additionally, pupil size during processing Caucasian faces was larger than during processing Chinese faces.     

Recognition of Faces: Own-Race Bias,Incentive, and Time Delay1

The ability of whites and blacks to correctly identify previously-seen faces of each race was assessed in a factorial design varying the length of time between inspection and recognition phases (immediate, 2 days, or 7 days) and incentive (possibility of monetary reward for accurate recognition). Recognition of faces of males was poorer after the longer time delays, but no comparable delay over time occurred for pictures of females. Subjects' criteria for responding became more lax after the longer time delays. Incentive had no significant direct impact on recognition accuracy or on subjects' criterion levels. A significant degree of own-race bias in recognition accuracy occurred, but only among whtte subjects. An own-race bias in response criteria occurred with subjects of both races. Implications of these findings are discussed.     

Comparing genderblind and colorblind ideologies in public and private contexts

People endorse colorblind and genderblind ideologies to appear unbiased toward race or gender, but although they have similar meanings these two ideologies have not been compared across public and private contexts. Given that laws make both gender and race discrimination illegal in public settings, such as schools and workplaces, people may hold similar ideologies in public, professional settings. However, differences in how gender and race are viewed in private contexts, such as friendships or families, could contribute to differential endorsement and use of the ideologies. The current research measured the self-reported endorsement of genderblind or colorblind ideologies in different contexts (Studies 2 and 3) and a behavioral manifestation of blindness within a decision-making paradigm (Studies 1, 2, and 3). In this paradigm, participants imagined themselves in an academic and/or social situation and chose which of two targets of different genders or races should join them in a group. Being blind to race or gender involved opting out of this choice. Participants also rated the appropriateness of using gender and race to make these decisions (Study 3). As predicted, in private, social situations participants (a) endorsed colorblindness more than genderblindness, (b) were more likely to show blind decision-making in cross-race than cross-gender choices, and (c) perceived race-based decisions as more inappropriate than gender-based decisions. In public (academic and work) situations, colorblind and genderblind measures were equivalent. Thus, people's beliefs about the value of being blind to gender and race differ in social situations and this difference has implications for equality.     

Everyone can be a winner: The benefits of competing in organized races for recreational runners

ABSTRACT

Participants in the study were 404 recreational runners. At the end of each week for three months they used an online diary to describe their psychological well-being for the week (a total of 4046 weeks), and they indicated if they had participated in an organized race each week (a total of 1111 races). Multilevel modeling analyses (weeks nested within persons) found that well-being, defined in terms of self-esteem, self-efficacy, life satisfaction, positive affect, and depressed affect, was higher during weeks in which participants had run in an organized race than it was during weeks in which they had not run in an organized race. Moreover, well-being was positively related to self-evaluations of performance in races. For recreational runners, finishing an organized race may represent the achievement of a goal, an achievement that increases well-being and may help maintain or increase the motivation to keep running.     

Telephone versus print delivery of an individualized motivationally tailored physical activity intervention: Project STRIDE.

OBJECTIVE: Given that only 25% of Americans meet physical activity recommendations, there is a need to develop and disseminate effective, evidence-based interventions to promote physical activity. The authors tested 2 delivery channels, telephone and print, to determine whether one was more effective in promoting physical activity. DESIGN: The authors randomly assigned 239 healthy, sedentary adults to (a) telephone-based individualized feedback, (b) print-based individualized feedback, or (c) contact control. Both intervention arms were guided by a motivationally tailored, theoretically driven computer expert system. MAIN OUTCOME MEASURES: Physical activity as measured by the 7-day Physical Activity Recall interview. RESULTS: At 6 months, both telephone and print arms significantly increased in minutes of moderate intensity physical activity compared with control, with no differences between the intervention arms. At 12 months, print participants reported a significantly greater number of moderate intensity minutes than both telephone and control participants, who did not differ. CONCLUSION: Results suggest that both telephone and print enhance the adoption of physical activity among sedentary adults; however, print interventions may be particularly effective in maintaining physical activity in the longer term.     

Do we all look alike to computers?

People are better able to recognize faces of their own race than those of other races. One explanation is that this 'other-race effect' is caused by lifelong experience in which faces from some races are more common than other races. A recent article by Furl et al. tests experience-based accounts of the other-race effect by giving computer algorithms of face recognition training on preponderantly Caucasian faces. The only algorithms that reliably produced other-race effects were those that created face representations distorted to emphasize features that individuated faces.     

Investigation of effects of face rotation on race processing: An ERPs study

Recent ERP research has indicated that the processing of faces of other races (OR) and same race (SR) as the perceiver differs at the perceptual level, more precisely for the N170 component. The purpose of the present study was to continue the investigation of the race-of-face processing across multiple orientations. Event-related brain potentials (ERPs) and performance were recorded when Caucasian participants were required to categorize by race Caucasian and African faces presented in eight different angles of orientation. Three main observations were made: (1) the face-sensitive N170 is modulated by the race of faces, being larger in response to OR compared to SR faces; (2) face rotation affected this component in the same pattern for both racial groups; (3) the N170-ORE progressively disappeared as the faces moved away from their canonical orientation at the right hemisphere only. Thus, the current findings suggest that configural/holisitic information is extracted from faces of both racial groups, but that upright OR faces require increased demands.     

Willingness to date across race: differences among gay and heterosexual men and women

Willingness to date members of other races was examined among 200 men with same-sex dating preference (n = 100) and opposite-sex dating preference (n = 100), and 200 women with same-sex dating preference (n = 100) and opposite-sex dating preference (n = 100) who were randomly selected from an Internet dating web site. Overall, results indicated a greater willingness among gay participants than heterosexual participants to date people of other races. A 2 (Sex) x 2 (Sexual Orientation) analysis of variance showed an interaction, with lesbian women more willing to date other races than gay men, while among heterosexual participants men were more willing than women to date other races. The role of mate selection theory, and the importance of the status afforded various races in U.S. society, were applied to interpret people's willingness to date other races.
