The Effects of a List of Food Items on Motivations to Eat in Dieters and Nondieters

A major health problem in our society is obesity, which is frequently caused by overeating or eating inappropriate foods. It has been suggested that the prevalences of food and food-related cues contribute to overeating and that dieters are particularly sensitive to food stimuli. In the present study, the influence of dieting was examined in a representative sample of college students who were exposed to a list of written food cues or who served as controls. The list of food cues increased motivation to eat in nondieting subjects, but did not appear to influence the appetites of dieters. It may be that dieters are more resistant to the effects of more subtle food cues, even when many cues are presented sequentially.     

Trust, Dependency, and Control in the Contemporary Organization

Trust is an essential element in productive and effective intraorganizational communication and interaction. The present study examined several consequences of trust in terms of influence strategies used and the frequency with which people interact with each other. The study also examined the extent to which the technology of work affects management's dependency on their employees. It was found that distrust of subordinates by managers (n = 275) was associated with the use of strong tactics of influence, little dependency on employees, and the use of personal-related characteristics to explain distrust. It was also found that distrust of managers by subordinates (n = 267) was associated with the use of strong methods of influence, less interaction, less attempts to influence, and the use of personal-related characteristics to explain lack of trust. These findings have clear implications for understanding the relation among worker trust, dependency, and social influence. The data suggest that both employees and employers could benefit from considering the importance of a trusting relationship in the workplace.     

Implicit learning of a repeated segment in continuous tracking: a reappraisal

Several prior studies (e.g., Shea, Wulf, Whitacre, & Park, 2001; Wulf & Schmidt, 1997) have apparently demonstrated implicit learning of a repeated segment in continuous-tracking tasks. In two conceptual replications of these studies, we failed to reproduce the original findings. However, these findings were reproduced in a third experiment, in which we used the same repeated segment as that used in the Wulf et al. studies. Analyses of the velocity and the acceleration of the target suggests that this repeated segment could be easier to track than the random segments serving as control, accounting for the results of Wulf and collaborators. Overall these experiments suggest that learning a repeated segment in continuous-tracking tasks may be much more difficult than learning from a repeated sequence in conventional serial reaction time tasks. A possible explanation for this difference is outlined.     

Terrorism, altruism, and patriotism: An examination of children’s letters to Santa Claus, 1998–2002

One annual tradition that children participate in is writing letters to Santa Claus. While parents and teachers pass on the general “rules” for the letters, the children often dictate the contents. The current study focused on whether the letters to Santa have changed over the years, especially in light of recent terrorist actions (for example, on the World Trade Center and Pentagon), and if so, how. Although many aspects of the letters to Santa have remained the same across the years, results indicated that requests for gifts for other people and the number of patriotic sentiments and drawings increased in 2001 and 2002. Also, compared to the year 2000, fewer gifts were requested in 2001. Santa Claus appears to be conceptualized as part demigod, part social worker, and part grandfather. The letters to Santa Claus provide a provocative and insightful look into the everyday life and world events that impact children.     

The development and validation of the pictorial motivation scale in physical activity

The purpose of the present research was to report the validation of the pictorial motivation scale in English. This scale is designed for adolescents and adults with an intellectual disability who are unable to independently read a questionnaire. The scale has a picture and phrase depicting 16 items related to participation in sport and physical activity; four for each of the following subscales, intrinsic motivation, self-determined extrinsic motivation, non self-determined extrinsic motivation, and amotivation. Phase 1 of the research describes the formal translation of the scale from French to English. Results from three studies conducted with Special Olympians (Phase 2) and adolescents in a special school (Phases 3 and 4) provided support for the internal consistency, test–retest reliability, and factorial and construct validity of the scale. Overall, the scale would appear to be sufficiently reliable and valid to warrant its continued use and further development.

Team Coordination in Basketball: Description of the Cognitive Connections Among Teammates

This study investigated team coordination in basketball using the course-of-action theoretical framework. The focus was on how the players were connected with their teammates' activities. The activity of five French basketball players (17.60 ± .89 years) was studied during an official match. The data were collected and processed according to a procedure defined for course-of-action analysis. The results were used to characterize the coordination modes among players and the team coordination network that was built. The processes that underlie team coordination are discussed (i.e., mutuality and awareness), and some directions for practical applications are addressed.     

Contributions of metaknowledge to retrieval of natural categories in semantic memory

Retrieving the answer to a general knowledge question has been shown to involve two metacognitive processes--a feeling-of-knowing that initiates the search of long-term memory and a willingness to continue searching until an answer can be confidently stated. To extend this model, college students were asked to retrieve as many members of 2 natural categories as they could in 1 min. Examination of the points at which they switched categories revealed that they searched longer in categories of higher potency, and they switched earlier when the other category was of higher potency. They also searched the first category longer when they were allowed to switch only once during a trial rather than as often as they wished. It was concluded that feeling-of-knowing maintained search of a category and also contributed to the willingness to continue searching, and the constraint on switching impacted the willingness to continue.     

Chronic self-destructiveness: Conceptualization,measurement, and initial validation of the construct

Individual differences in various behaviors suggest that those who are primarily motivated by current emotional factors are more likely than those motivated by more distant cognitive considerations to engage in acts that are ultimately self-destructive. To assess and explore these behavioral differences, 12 samples of undergraduate subjects, totaling 864 (527 females, 337 males), a group of 15 businesswomen, and 111 male VA patients were used to develop a measure of this construct in a series of reliability and construct validity studies. By means of internal-consistency item analyses, two cross-validated 52-item measures of chronic self-destructiveness were constructed for males and females. Reliability was established with respect to internal consistency (alpha coefficients range from .73 to .97) and temporal consistency over a 1-month period (test-retest correlations range from .90 to .98). There is a slight drop in chronic self-destructiveness scores across age groups. Test scores were found to be positively related to external locus of control, negatively related to Type A coronary-prone behavior, and unrelated to either social desirability response set or need for achievement. Individuals high in chronic self-destructiveness, compared to those with low scores, are more likely to be in treatment for drug or alcohol abuse, to report having cheated in courses, to have had traffic violations, to report having gone through a rebellious stage in adolescence, and to postpone obtaining a medical test for cancer. Chronic self-destructiveness appears to be a personality dimension that affects behavior across a wide range of ages and situations.We wish to thank John Wapner for his assistance in obtaining data in the clinical sample.     

More accurate size contrast judgments in the Ebbinghaus Illusion by a remote culture

The Ebbinghaus (Titchener) illusion was examined in a remote culture (Himba) with no words for geometric shapes. The illusion was experienced less strongly by Himba compared with English participants, leading to more accurate size contrast judgments in the Himba. The study included two conditions of inducing stimuli. The illusion was weaker when the inducing stimuli were dissimilar (diamonds) to the target (circle) compared with when they were similar (circles). However, the illusion was weakened to the same extent in both cultures. It is argued that the more accurate size judgments of the Himba derive from their tendency to prioritize the analysis of local details in visual processing of multiple objects, and not from their impoverished naming.
