Deceit,distrust and the social milieu: Application of deception research in a troubled world

This essay draws together deception detection research and explains its relevance to decision‐making in today's social milieu. Major areas of research focus are described including the differential effects of observational conditions, the correspondence between perceived and actual signs of deception, training observers to detect deception, and communicating with suspected deceivers. Communicator relationships, observer characteristics and observer professions are considered in relation to accurate deception detection, as is overall confidence in the ability to detect deception. Implications are drawn for legal, organizational, sales, medical and relational settings.     

Narrative approaches to raising consciousness about sexual harassment: From research to pedagogy and back again

In this paper we discuss narrative from both a theoretical and pedagogical perspective. After briefly reviewing the theoretical possibilities of narrative for addressing the problem of sexual harassment, we discuss how feminist pedagogy both draws from and advances our notions of narrative. We then focus on three forms of narrative as they are used to raise consciousness concerning the issue of sexual harassment. The three specific approaches include: (1) the personal narrative, (2) the case study, and (3) the interactive narrative or collective story. After providing illustrations of these three approaches as they are used in academic settings, we explore the possibility that utilizing these approaches might provide heuristic tools for the classroom instructor, useful strategies for the workplace practitioner, and insight into the theoretical exploration of sexual harassment.     

Is Inclusion an Illusion? An Examination of National and State Trends Toward the Education of Students with Learning Disabilities in General Education Classrooms

The inclusion of students with learning disabilities (LD) remains one of the more controversial issues in special education. Although research evidence seems to reveal that students with LD should spend most of the school day in the general education classroom, little data are available regarding the extent to which states are moving toward educating these students in less restrictive settings. This investigation was conducted to examine national and state data related to changes that occurred during the 1990s in educating students with LD in less restrictive settings. The results revealed that little change occurred across the United States as a whole, and that only 15 states moved toward educating students with LD in less restrictive settings during this time. The findings of this investigation further revealed that much of the apparent movement toward educating students with LD in general education classrooms is largely an illusion, explained primarily by the increasing identification rate for students with LD. The implications of these findings for future research and practice are discussed.     

Caffeine ingestion enhances perceptual responses during intermittent exercise in female team-game players

We examined the influence of caffeine supplementation on cognitive performance and perceptual responses in female team-game players taking low-dose monophasic oral contraceptives of the same hormonal composition. Ten females (24 ± 4 years; 59.7 ± 3.5 kg body mass; 2–6 training sessions per week) took part in a randomised, double-blind, placebo-controlled crossover-design trial. A 90-min intermittent treadmill-running protocol was completed 60 min following ingestion of a capsule containing either 6 mg ? kg^?1 anhydrous caffeine or artificial sweetener (placebo). Perceptual responses (ratings of perceived exertion (RPE), feeling scale (FS), felt arousal scale (FAS)), mood (profile of mood states (POMS)) and cognitive performance (Stroop test, choice reaction time (CRT)) were completed before, during and after the exercise protocol, as well as after ~12 h post exercise. Caffeine ingestion significantly enhanced the ratings of pleasure (P = 0.008) and arousal (P = 0.002) during the exercise protocol, as well as increased vigour (POMS; P = 0.007), while there was a tendency for reduced fatigue (POMS; P = 0.068). Caffeine ingestion showed a tendency to decrease RPE (P = 0.068) and improve reaction times in the Stroop (P = 0.072) and CRT (P = 0.087) tests. Caffeine supplementation showed a positive effect on perceptual parameters by increasing vigour and a tendency to decrease fatigue during intermittent running activity in female games players taking low-dose monophasic oral contraceptive steroids (OCS).     

Football experts versus sports economists: Whose forecasts are better?

Given the uncertainty of outcome in sport, predicting the outcome of sporting contests is a major topic in sport sciences. This study examines the accuracy of expert predictions in the German Bundesliga and compares their predictions to those of sports economists. Prior to the start of each season, a set of distinguished experts (head coaches and players) express their subjective evaluations of the teams in school grades. While experts may be driven by irrational sentiments and may therefore systematically over- or underestimate specific teams, sports economists use observable characteristics to predict season outcomes. The latter typically use team wage bills given the positive pay–performance relationship as well as other factors (average team age, tenure, appearances on national team, and attendance). Using data from 15 consecutive Bundesliga seasons, the predictive accuracy of expert evaluations and sports economists is analysed. The results of separate estimations show that relative grade and relative wage bill significantly affect relative points, while age, tenure, appearances, and attendance are insignificant. In a joint model, relative grade and relative wage bill are still statistically significant, suggesting that the two types of predictions are complements rather than substitutes. Consequently, football experts and sports economists seem to rely on completely different sources of information when making their predictions.     

Young Children's Depiction of Contrast in Human Figure Drawing: standing and walking

Children aged 4 to 10 years old were asked to draw a person standing absolutely still and a person walking very fast so that someone not present would know from the pictures alone what had been depicted. Even at four some children were able to convey the difference to a viewer and there was increasing success with age. The number of differentiating cues increased with age and there was an age‐related trend in the order in which specific cues appeared in the drawings. The ability of the children to respond flexibly to the task gives no support to notions of rigid mental representations determining what young children can draw. It is argued that contrast tasks are a useful tool for investigating problem solving skills in the domain of drawing and could be used to extend children's skill by providing an occasion for explicit dialogue about how representational information is conveyed to a viewer.     

Task motivation: Learner selection of intrinsic versus extrinsic orientations

The choice behavior of 24 college-age subjects within a computer problem-solving task was investigated as they controlled and selected problem difficulty levels which either maximized intrinsic interest or extrinsic reward. While playing a computerized version of the game Mastermind, subjects selected and attempted problems from a variety of difficulty levels during 18 15-minute sessions. Within selected periods of extrinsic reward availability, subjects were shown to select problems which were most efficiently solved, thus maximizing extrinsic reward; however, repeated task exposure produced selections that increased the task's challenge levels and its subsequent intrinsic interest. Following the removal of the extrinsic rewards, subjects immediately returned to their pre-reward intervention levels of difficulty.

Reading and Writing - Educators’ content knowledge is considered a key determinant of classroom practices and thus children’s learning. In this study, we examine the nature of...
