Psychology ethics down under: a survey of student subject pools in Australia

A survey of the 37 psychology departments offering courses accredited by the Australian Psychological Society yielded a 92% response rate. Sixty-eight percent of departments employed students as research subjects, with larger departments being more likely to do so. Most of these departments drew their student subject pools from introductory courses. Student research participation was strictly voluntary in 57% of these departments, whereas 43% of the departments have failed to comply with normally accepted ethical standards. It is of great concern that institutional ethics committees apparently continue to condone, or fail to act against, unethical research practices. Although these committees have a duty of care to all subjects, the final responsibility for conducting research in an ethical manner lies with the individual researcher.     

Engagement and recruitment for family therapy research in community settings

Based on the recruitment experience in a family therapy research project with heroin addicts, this paper explores the difficulties of researcher networking with other social service agencies. Concepts from contextual family therapy are used to explore four general areas that contribute to successful intra-agency relationships: 1) Evaluating the nature of larger system relationships; 2) identifying the resources and needs of a clinic; 3) joining with the counseling staff; and 4) addressing the impact of public policy and ideology on clinic life. A case of engaging one clinic is presented and nine guidelines for engaging large community settings for participation in family therapy research are offered. These areas are considered in light of the relational dynamics that arise when working with multiple social service systems.An earlier version of this paper was presented at the American Family Therapy Association conference in Washington, DC, June 1986. The authors are grateful to the recruitment staff of the Intergenerational Family Therapy Project: Guillermo Lopez, Bart Rubin, Sharara Godfry, and Armando Chenyek. This research was supported in part by a grant to Guillermo Bernal from the National Institute on Drug Abuse (DA03543).     

Patterns of interocular transfer of visuomotor coordination reveal differences in the representation of visual space

Acquisition and interocular transfer of adaptation to optical transformations of input were examined in strabismic and orthotropic subjects. Distinct patterns of behavior were displayed by three groups: strabismic alternating suppressors, strabismic and orthotropic constant suppressors, and orthotropes with normal binocularity of vision. It is suggested that these behaviors result from the way in which visual space is represented in each group, an outcome of the pattern of use of the eyes during early development. The conditions for modification of the representation of visual space appear to parallel those for initial acquisition.     

Sexual identity, attractions, and behavior among young sexual-minority women over a 2-year period

Previous research suggests that the sexual identities, attractions, and behaviors of sexual-minority (i.e., nonheterosexual) women change over time, yet there have been few longitudinal studies addressing this question, and no longitudinal studies of sexual-minority youths. The results of 2-year follow-up interviews with 80 lesbian, bisexual, and "unlabeled" women who were first interviewed at 16-23 years of age are reported. Half of the participants changed sexual-minority identities more than once, and one third changed identities since the first interview. Changes in sexual attractions were generally small but were larger among bisexuals and unlabeled women. Most women pursued sexual behavior consistent with their attractions, but one fourth of lesbians had sexual contact with men between the two interviews. These findings suggest that there is more fluidity in women's sexual identities and behaviors than in their attractions. This fluidity may stem from the prevalence of nonexclusive attractions among sexual-minority women.     

Genetic Cancer Risk Assessment and Counseling: Recommendations of the National Society of Genetic Counselors

These cancer genetic counseling recommendations describe the medical, psychosocial, and ethical ramifications of identifying at-risk individuals through cancer risk assessment with or without genetic testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors Cancer Genetic Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment and counseling as well as the personal expertise of genetic counselors specializing in cancer genetics. The recommendations are intended to provide information about the process of genetic counseling and risk assessment for hereditary cancer disorders rather than specific information about individual syndromes. Key components include the intake (medical and family histories), psychosocial assessment (assessment of risk perception), cancer risk assessment (determination and communication of risk), molecular testing for hereditary cancer syndromes (regulations, informed consent, and counseling process), and follow-up considerations. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider's professional judgment based on the clinical circumstances of a client.     

Emotion-induced amnesia in rats: working memory-specific impairment, corticosterone-memory correlation, and fear versus arousal effects on memory

We have shown previously that psychological stress (predator exposure) impairs spatial memory in rats. We have extended that finding here to show that predator stress selectively impaired recently acquired (hippocampal-dependent) spatial working memory without affecting long-term (hippocampal-independent) spatial reference memory. We also investigated why predator exposure impairs memory. Was spatial memory impaired because of the fear-provoking aspects of predator exposure or only because the cat was a novel and arousing stimulus? If the latter possibility was correct, then any novel and arousing stimulus, independent of its emotional valence (i.e., aversive or appetitive), would impair memory. We found that spatial working memory was not impaired when the male rats were exposed to a sexually receptive female rat, a stimulus that was novel and arousing to them, but not aversive. We also found that there was an equivalent increase in serum corticosterone levels in male rats exposed to either a cat or a female rat, but only the cat-exposed rats exhibited a significant correlation between corticosterone levels and impaired memory. Overall, this series of experiments demonstrates that (1). predator stress selectively impaired working (hippocampal-dependent), but not reference (hippocampal-independent), memory; (2). a fear-provoking stimulus, and not merely novelty and increased arousal, impaired spatial memory; and (3). increased corticosterone levels correlated with impaired spatial working memory only under predator exposure, that is, fear-provoking conditions.     

Early developments in the ability to understand the relation between stimulus and reward

Delayed nonmatching to sample (DNMS) is used to test the recognition memory function dependent on the medial temporal lobe. Children cannot succeed on this task until about 21 months. Because robust recognition is present well before then, the late emergence of another ability must account for the late success on DNMS. Evidence is presented here that the critical late-maturing competence is the ability to grasp the relation between stimulus and reward--that is, to understand that the stimulus is a symbol or marker for the reward. Infants of 9 and 12 months were tested on 3 conditions of DNMS. A sample object was presented. After a delay, the sample and a novel object appeared; choice of the novel object was rewarded. In the standard task, the reward was in a well beneath the stimulus. In the verbal-reward condition the reward was not a separate object but was praise and applause. In the Velcro condition, the reward, although a separate and separable object, was attached to the base of the stimulus. Most infants at both ages succeeded in the verbal-reward and Velcro conditions but not in the standard condition.     

Individual differences in adolescents' sympathetic and parasympathetic functioning moderate associations between family environment and psychosocial adjustment

The present study tested whether individual differences in autonomic nervous system functioning interact with environmental risk factors to predict adolescents' psychosocial functioning. The authors assessed skin conductance and respiratory sinus arrhythmia at rest and during laboratory stressors in 110 14-year-olds. Subsequently, adolescents and their mothers provided both questionnaire and daily diary data (over 10 days) on emotional and interpersonal functioning. The authors found stronger associations between environmental risk factors (having a single-mother household or a mother with high internalizing problems) and psychosocial outcomes (externalizing problems, daily negative affect, and daily interaction quality) among youths with specific patterns of tonic and stress-induced sympathetic and parasympathetic nervous system activity, but the pattern of moderating effects differed between boys and girls. The findings support the notion that individual differences in autonomic functioning index variation in youth's susceptibility to environmental risk factors.     

The short-form Buss-Perry Aggression Questionnaire (BPAQ-SF): a validation study with federal offenders

The 12-item short form of the Buss-Perry Aggression Questionnaire (BPAQ-SF) was originally developed by Bryant and Smith (2001) and modified and confirmed using confirmatory factor analysis with mentally ill offenders by Diamond, Wang, and Buffington-Vollum (2005). In the current study, construct validity of the BPAQ-SF was assessed with a sample of 1,181 male and 435 female general population federal offenders. Confirmatory factor analysis supported the four-factor structure. Tests confirmed factorial invariance across gender for all loadings and covariances. Reliabilities were found to be adequate and comparable to those found in the studies cited above. Concurrent validity was supported by high correlations between the subscales of the BPAQ-SF and several relevant subscales on the Personality Assessment Inventory (PAI). In addition, those offenders with prior history of violence, head injuries, childhood abuse, residential treatment, custody, or foster care as a child had higher scores on the BPAQ subscales.
