The Influence of Perpetrator Exposure Time and Weapon Presence/Timing on Eyewitness Confidence and Accuracy

Crimes can occur in a matter of seconds, with little time available for an eyewitness to encode a perpetrator's face. The presence of a weapon can further exacerbate this situation. Few studies have featured mock crimes of short duration, especially with a weapon manipulation. We conducted an experiment to investigate the impact of weapon presence and short perpetrator exposure times (3 vs. 10 seconds) on eyewitness confidence and accuracy. We found that recall concerning the perpetrator was worse when a weapon was present, replicating the weapon focus effect. However, there was no effect on eyewitness identification accuracy. Calibration analyses revealed that all conditions produced a strong confidence–accuracy relationship. Confidence–accuracy characteristic curves illustrated almost perfect accuracy for suspect identifications at the highest levels of confidence. We conclude that weapon presence during a brief crime does not necessarily result in negative consequences for either eyewitness identification accuracy or the confidence–accuracy relationship.

A pilot study of women’s affective responses to common and uncommon forms of aerobic exercise

Objective: To test the extent to which participants exposed to an uncommon versus common exercise stimulus would result in more favourable affect at post-task.

Design: Experimental design. Participants (N = 120), American women aged 18–45 years, were randomly assigned to complete 30-min of either the uncommon (HOOP; n = 58) or common (WALK; n = 62) exercise stimulus.

Main outcome measures: Self-reported affect and intentions for future exercise were measured before and after the 30-min exercise bout.

Results: Analyses of covariance were run to compare post-task affect across the HOOP and WALK conditions. At post-task, participants assigned to HOOP reported more positively valenced affect, higher ratings of positive activated affect, lower ratings of negative deactivated affect, and stronger intentions for future aerobic exercise compared to participants assigned to WALK.

Conclusions: Participants who completed an uncommon bout of aerobic exercise (HOOP) reported more favourable affect post-exercise, as well as stronger intentions for future exercise, compared to participants who completed a common bout of aerobic exercise (WALK). Future work using a longitudinal design is needed to understand the relationships between familiarity with an exercise stimulus, affective responses to exercise, motivation for future exercise behaviour and exercise maintenance over time.     

The Ontogeny of Long‐Term Retention During the Second Year of Life

Developmental changes in retention were assessed in two experiments with 18‐ and 24‐month‐old infants. In both experiments, infants were tested in a deferred imitation paradigm. In Experiment 1, independent groups of infants were tested either immediately or after delays of 1, 14, 28 or 56 days. There was no age‐related difference in the spontaneous production of target actions (baseline) or in immediate imitation. There were age‐related changes in retention after longer delays. Eighteen‐month‐olds exhibited retention for 14 days and 24‐month‐olds exhibited retention for at least 56 days. In Experiment 2, the maximum duration of retention by 24‐month‐olds was assessed. Independent groups of infants were tested after 3 or 6 months. Infants exhibited some evidence of retention after 3 months; however, forgetting was complete after 6 months.     

Metaphorical Mapping: The Arts in Graduate Theological Education

Doctoral students in Bible, theology, ethics, history, preaching, worship, pastoral care, and Christian education come together for a required seminar in teaching. Assignments include reading and discussion, student‐led teaching demonstrations, and the ‘metaphorical mapping’ of each student's field of study. In developing their ‘metaphorical maps’ students use artistic and expressive media to demonstrate their understanding of their field. The assignment has been successful in establishing an open and mutually respectful climate in the classroom, in fostering a pattern of critical reflection on teaching, and in demonstrating appropriate inclusion of personal experience in the academic classroom.     

Behavior and autonomic nervous system function assessed via heart period measures: The case of hyperarousal in boys with fragile X syndrome

Physiological responses may inform us about and help us to interpret behavioral responses. For example, hyperarousal may be a source of behavior problems in children with fragile X syndrome (FXS). To evaluate this approach, we examined heart period data in specific contexts in boys with FXS and in normally developing chronological-age-matched boys. Spectral analysis was used to evaluate the parasympathetic and sympathetic nervous systems’ contributions to heart period. Boys with FXS had shorter interbeat intervals, lower parasympathetic activity, and similar sympathetic activity. Also, the groups were differentially responsive to experimental challenge. These results have important implications for our understanding of the basic nervous system dysfunction in FXS and for the strategies likely to be effective in terms of pharmacological intervention with these children. These methods can be applied to a variety of contexts and populations, including children who are sensory defensive, socially avoidant, inattentive, or hyperactive.     

Gender and Infertility: A Relational Approach to Counseling Women

Much of the research on infertility reinforces differing effects for women and men, with women reporting more serious repercussions medically, psychologically, and socially. However, the unique counseling needs of infertile women have not been addressed through traditional counseling theory. The Relational Model (J. V. Jordan, 1995) of women's development is a theory that explains women's development in a context of relationships, specifically relationships that promote growth for self and others. This model is applied to counseling women who are experiencing infertility, and a case presentation is provided to illustrate the approach.     

Ethical Guidelines for Counselors Working With Older Adults

Counselors working with older adults may encounter situations that are not directly addressed by the ethical standards of the American Counseling Association (1995). After an extensive review of the literature, the Standards Committee of the Association for Adult Development and Aging (1998) identified 3 areas of concern: older adults with cognitive impairments, older adults who are the victims of abuse, and older adults with a terminal illness. This article examines the unique needs of older adults with these concerns and proposes guidelines for counselors working with such clients.     

The Wheel of Wellness Counseling for Wellness: A Holistic Model for Treatment Planning

A holistic model of wellness and prevention over the life span was presented by T. J. Sweeney and J. M. Witmer (1991) and J. M. Witmer and T. J. Sweeney (1992). Recent advances in research and theory related to wellness support modifications of the original model. The foundation for the model is examined, research related to each component is explored, and implications for use of the model as a basis for counseling interventions are presented.     

Networking a computer-aided guidance system within higher education institutions: practice and potential

A number of higher education institutions have networked PROSPECT (HE) to make it available throughout the institution. The impact of such networking was evaluated, based on visits to six of these institutions and on logged statistical data. The rationale for networking, and implementation strategies adopted, are discussed. The quantitative data provided less evidence of the reduced quality of usage than had been anticipated. Qualitative data suggested that networking provided easier access in terms of both location and time: this removed the need to ration usage of the system, thus making it easier to consider opportunities for structured usage, and to justify access to non-core groups. There was no evidence of any reduction in the use of the careers services. Examples are presented of PROSPECT (HE) being linked with a variety of other careers activities. Overall, the evidence suggests that the benefits of networking outweigh the risks.     

Comparing the mental health needs of female and male incarcerated juvenile delinquents

The present study was undertaken to survey the prevalence of mental disorder in juvenile justice facilities and to compare the mental health needs for females and males. Girls displayed significantly more mental health needs than boys. The estimated prevalence of mental disorder for boys was 27%, compared with 84% for girls. The difference is highly significant and is discussed in terms of service system issues in juvenile justice that affect males and females differently. ©1997 John Wiley & Sons, Ltd.
