Sexual assault: Myths and stereotypes among Australian adolescents

Myths and stereotypes about sexual assault reflect a society which excuses perpetrators of assault and blames victims for failing to control men's sexuality. Such views are well-established by early adulthood, but there is little research with adolescents. This study surveyed two hundred forty-four 14–16 year old Australian high school students (105 male, 139 female), of Anglo-European descent. Males were significantly more likely to endorse sexual assault myths, to agree that forced sex was acceptable in some situations, and to hold false stereotypes about sexual assault. Males also held more restrictive attitudes toward women's roles and endorsed a greater level of sexism in dating relationships. This suggests that male and female adolescents have differing expectations of dating relationships, which may underlie sexual assault within relationships. Assault-supportive attitudes are apparent at a young age, supporting the need for educational and social interventions targeting young people.     

Effects of task instructions and oscillation frequency on bimanual coordination

Increases in the oscillation frequency of bimanual movements produce a switch from an anti-phase (180° relative phase) to an in-phase (0° relative phase) coordination pattern. This finding is observed when subjects are instructed not to intervene when they feel themselves slipping out of the anti-phase pattern. The question addressed in this study concerned how performance would be affected if subjects were instructed to try to maintain the pattern at all times. This issue was addressed using two separate groups of subjects: one group was given the do not intervene instructions, the other group was told to try to stay with the pattern at all times. Forearm rotations were tested in 15 s trials, paced by an auditory metronome set at 1.0, 1.5, 2.0, 2.5, and 3.0 Hz. Frequency distributions of the point estimates of relative phase were analyzed. The Do not Intervene group replicated previous findings, as indicated by the development of a bimodal histogram of relative phase distributions with increases in oscillation frequency. However, a very different pattern of findings emerged with increases in oscillation frequency for the group told to stay with the anti-phase pattern. Rather than a bimodal distribution being developed, the data maintained 180° as its central tendency — no secondary distribution developed around 0° relative phase. These data suggest that volitional control can over-ride the inherent dynamical tendencies of the motor system.     

From dialectic to organization: Bogdanov’s contribution to social theory

This paper situates Bogdanov in the context of social theory generally and socialist theory in particular. It outlines briefly the principal characteristics of his mature system, and assesses the strengths and weaknesses of his approach to the fundamental problems of social thought. The paper devotes particular attention to the problem of just how systems develop from less complex to more complex forms of organization, and evaluates Bogdanov’s solution to this problem against the background of populist, social democratic, and Leninist alternatives.     

The pain behavior scale: Modification and validation for outpatient use

The present study investigated the validity of an inpatient pain behavior rating scale modified for outpatient use. A series of 43 consecutive outpatients referred for evaluation of chronic pain was examined using the Pain Behavior Scale (PBS) and other psychometric instruments. Analyses revealed significantly higher Pain Behavior Scale scores for low back and multiple pain-site groups. The results also indicated a high degree of internal consistency of the scale. A multiple regression analysis, predicting observed pain behavior from reported pain behavior, indicated that decreased activity accounted for 32% of the variance in the PBS score. A similar regression for pain experience found that the pain level and the sensory scale score on the McGill Pain Questionnaire accounted for 39% of the PBS variance. Psychological characteristics including disease conviction, self-control, depression, and anxiety explained 45% of the variability in the PBS score. Thus, the scale is related to pain intensity, interference with activities, and a variety of psychological characteristics. The scale provides a measure of observable pain behavior that is also relatively independent of these clinical data sources. The Pain Behavior Scale as modified for outpatient use provides a brief index of pain behavior with potential use in the comprehensive evaluation of the pain patient.     

A critical review of theS/L reliability index

The meaning and properties of a commonly used index of reliability, S/L,were examined critically. It was found that the index does not reflect any conventional concept of reliability. When used for an identical behavioral observation session, it is not statistically correlated with other reliability indices. Within an observation session, the standardizing measure of Lis beyond the control of the investigator. Furthermore, the reason for the choice of Las the standard is unclear. The role of chance agreement in S/Lis not known. The exact interpretation of the index depends on which observer reports L.Overall the conceptual and mathematical meaning of S/Lis dubious. It is suggested that the S/Lindex should not be used until its nature is shown to be a measure of reliability. Other approaches such as the intraclass correlations and generalizability coefficients should be used instead.The authors are indebted to Johnny Matson for his critique of an earlier version of this paper.     

On doing research: the dream and the reality

The principal concern of this essay is to offer practical and personal guidance to professional therapists who wish to engage in research in family therapy. It is not a paper about research design or experimental/observational/survey methods; rather the focus is upon the experience of engaging in research. It attempts to destroy a few common myths about researchers, research, and the motives of researchers and those whom they research. Research is seen as a continuing and evolving process (rather than a product) which can intrude in many aspects of the individual's life; it can affect motives, working relationships, organizational composure, personal family life, and personal self-esteem. Research is thus like most other forms of employment. Research, as an activity, must be seen in terms of systems dynamics, resistance to change, and hopefully, in terms also, of self-actualization and the refreshment of professional parts that other addictions cannot reach.
Recommendations are made for the structuring of research activity, in the light of the research model presented.     

Spontaneous startle activity in newborn infants

Spontaneous startles have been reported to occur most frequently in quiet sleep, less frequently in active sleep and drowse, and relatively nonexistent in the waking states. These findings may be a result of a focus on infants whose prenatal histories reflect a restricted range of the conditions to which normal newborns are exposed. The present study examined the spontaneous startle behavior of 30 newborn infants characterized by high numbers of obstetric complications and by indicators of prenatal malnutrition, but within the range of normal, healthy newborns. In this sample, startles were not limited to the sleep and drowse states. Because individual differences in a number of neonatal behaviors have been related to autonomic nervous system (ANS) functioning, the different pattern of spontaneous startles observed in this sample may be related to the functional integrity of this system.     

Learned helplessness deficits: Uncontrollable outcomes or perceived failure?

An experiment is described showing that learned helplessness deficits are produced by prior exposure to uncontrollable outcomes rather than perceived failure. Although the controllability manipulation did produce differences in perceived success or failure, similar differences were also induced by means of instructional feedback. These latter differences, within the controllable and uncontrollable groups, were not associated with poorer performance by subjects given failure feedback. Moreover, the instructional feedback did not influence subjects' perceptions of controllability or uncontrollability. The results confirm that helplessness deficits cannot be explained as reactions to task failure.This research was supported by Research Grant A28015473 from the Australian Research Grants Scheme.     

Finite-state recall revealed by backward learning curves constructed from confidence ratings

Two experiments were carried out to show that the constancy of Type II d’ in recall is not an artifact, but is due to finite-state processes as suggested by Bernbach (1967). The following conclusions were reached: (1) The constancy of Type II d’ is not an artifact due to the inclusion of intralist intrusions in the class of incorrect responses; (2) backward learning curves constructed from confidence ratings gave clear evidence of all-or-none recall; (3) recall appeared to be all or none whether the subjects learned by rote or with a mnemonic; (4) the discriminability index derived from Luce’s (1959) choice theory did not exhibit constancy over trials, unlike Type II d’ and despite the fact that backward rating curves indicated all-or-none processes.
