Does Positive Perception of Oneself Boost Learning Motivation and Performance?

We examine whether core self‐evaluations (CSEs) affect learning motivation and performance beyond individual‐level established predictors of general mental ability and conscientiousness. Based on self‐regulation theories, we develop and test a process model, whereby learning motivation mediates the effects of CSE on performance. We also compare the explanatory value of single and multidimensional models of learning motivation. Using a longitudinal design and data from 631 students, we provide support for the proposed model, indicating the usefulness of CSE as another important, indirect predictor of performance in a learning setting via multiple dimensions of learning motivation: self‐efficacy, goal setting, and goal commitment. The results also indicate the superiority of the multidimensional model of learning motivation over the unidimensional model of learning motivation as a mediator. We conclude with the discussion of theoretical and practical implications of this finding for management education.     

An experimental study of behavioural coping strategies in free-ranging female Barbary macaques (Macaca sylvanus)

A fundamental goal of stress research is to understand how individuals cope with challenges. Studies on a range of vertebrate species suggest that three groups of behaviour-affiliative, aggressive and self-directed behaviours-serve as coping strategies. To date, experimental studies of coping behaviour have tended to be conducted in captive conditions; the limited number of studies in free-ranging or wild settings have been observational in nature. We investigated coping behaviours in free-ranging female Barbary macaques (Macaca sylvanus) at Trentham Monkey Forest, UK, using an experimental playback approach to quantify subjects' responses to mildly aversive threat-grunts. Compared to silent control trials, playbacks of threat-grunts increased aggressive behaviours and one of the two self-directed behaviours examined (self-scratching). No such differences were seen for self-grooming, or for any affiliative behaviour. Elevations in the rate of one measure of aggression, lunging, were positively related to an average measure of adrenocortical activity (median faecal glucocorticoid metabolite levels over the study period). Evidence from females in a variety of Old World monkey species, including Barbary macaques, indicates that affiliative behaviours have an important role in coping with stressful events in the medium to longer term. Our results suggest that, in the short term, female Barbary macaques may use aggressive rather than affiliative behaviours in response to mild stress. These findings highlight the importance of considering how coping mechanisms may vary over time after a stressor, and how coping mechanisms relate to adrenocortical activity. Playback approaches like ours provide a powerful, flexible tool to explore issues such as this in free-ranging and wild animal populations.     

Acceptance and Commitment Therapy for a Heterogeneous Group of Treatment-Resistant Clients: A Treatment Development Study

Acceptance and commitment therapy (ACT) has been shown to have broad applicability to different diagnostic groups, and there are theoretical reasons to consider its use with clients with chronic mental health problems. We report an innovative treatment development evaluation of ACT for a heterogeneous group of ”treatment-resistant clients” (N = 10) who had attended a mean of 3.5 previous psychological interventions. All clients had Axis I presentations and half met diagnostic criteria for Axis II disorders. Functioning, assessed at pre- and postintervention, and at 6- and 12-month follow-up, showed improvements over time on all primary outcome measures, driven largely by significant changes occurring between baseline and 6-month follow-up. Improvements were associated with ACT processes of change. The data thus suggest that a broad range of clients who had not benefited from standard care may benefit from ACT.     

Lana Chimpanzee Learns to Count by “Numath”: A Summary of a Videotaped Experimental Report

This paper summarizes a videotaped presentation (Rumbaugh, Savage-Rumbaugh, Hopkins, Washburn, & Runfeldt, 1987) of computerized training programs whereby an adult female chimpanzee, Lana (Pan troglodytes), learned to use a joystick to remove from a screen the number of boxes appropriate to the value of a randomly selected Arabic numeral 1, 2, or 3. Initial training provided a variety of cues, both numeric and otherwise, to support correct performance. Across software programs, all cues other than numeric ones were deleted. In the final test, Lana was correct on over 80% of trials in which there was no residual feedback of intratrial events and where only her memory of those events could provide the cue to indicate that she had removed boxes in accordance with the value of the target numbers and should terminate the trial. The tape is narrated and consists of video recordings of Lana's performance on each software program.     

GROUP TRAINING OF CONSERVATION SKILLS WITH CHILDREN FROM A NON-TECHNOLOGICAL CULTURE*

Group training of conservation of length was undertaken with primary school children in Botswana. Each group contained 10 subjects of mixed academic ability. Three methods of training were used: (1) teacher demonstration accompanied by responsive group recitation, (2) limited manipulation of training materials by students, (3) full manipulation of training materials by students. The three training methods were effective in producing learning, retention, and generalization of conservation. The results are discussed in terms of Piaget's views on the role of environmental influences and the function of action in the development of cognitive structures. The value of Piagetian concepts for non-technological societies also is discussed.     

AN EVALUATION OF THE RELATIONSHIP BETWEEN RECEPTIVE SPEECH SKILLS AND EXPRESSIVE SIGNING

We examined the effects of receptive speech on the acquisition of manual signing among three mentally retarded children. In an alternating treatments design, we compared the acquisition of expressive signs that were, versus were not, in a child's receptive vocabulary. The children were trained via total communication in which pictorial referents were named during sign training. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. We conducted posttests to assess the stimulus control of signing and any changes in expressive and receptive signing and speech. Observed changes in performance could be accounted for by attention to aspects of the stimulus complex during training and functional equivalence of stimuli established by training.     

Female attractiveness and eating disorders: Do children's television commercials play a role?

The differential rate of eating disorders in males and females has been partially attributed to gender socialization. Media influences, even in children's programming, may contribute to the greater emphasis on physical attractiveness for girls compared to boys. Commercials from Saturday morning cartoon programming were analyzed for the number of male/female main and supporting characters, sex of narrator, sex of intended consumer, and appearance enhancement of person, doll, or animal. A majority of the commercials (60.6%) were for food products. Chi-square comparisons revealed significantly more male than female main characters and narrators in these commercials. Of those commercials (13.8%) scored for appearance enhancement, all male/female chi-square comparisons were significant with more female supporting characters, female main characters, female narrators, and female consumers. With the combined emphases on food and, for girls, on appearance, support for possible influences of commercials in eating disorders is noted.     

Sex and sex-typing effects on computer attitudes and aptitude

Previous research has supported a sex difference favoring males on computer-related variables. This study examines the potential mediating effects of psychological sex typing on computer variables. One hundred twenty-five undergraduates were administered measures assessing sex typing, computer experience, computer attitudes, computer self-efficacy, and computer aptitude. When the effects of specific computer experience and sex-typing variables were removed using analyses of covariance, male/female comparisons on computer aptitude and self-efficacy variables were no longer significant. Participant sex as well as masculinity and several computer experience variables were significant in the computer attitude analysis.
