Evaluating stranger and acquaintance rape: The role of benevolent sexism in perpetrator blame and recommended sentence length

In most jurisdictions, the law does not recognize the distinction between stranger and acquaintance rape. However, these two types of rape seem to elicit different responses from both lay observers and legal practitioners. Two studies investigating the role of benevolent sexism (BS) in accounting for participants' responses to acquaintance vs. stranger rape perpetrators are reported. Participants were presented with vignettes describing either an acquaintance rape or a stranger rape. As predicted, relative to low-BS individuals, participants who scored high in BS attributed less blame ( Study 1) and recommended shorter sentences ( Study 2) for the acquaintance rape perpetrator. Benevolent sexism was unrelated to reactions to the perpetrator in the stranger rape condition.

The association between continuous naming speed and word reading skill in fourth- to sixth-grade children

A correlational study was designed to examine the general processing speed and orthographic processing speed accounts of the association between continuous naming speed and word reading skill in children from fourth to sixth grade. Children were given two tests of each of the following constructs: word reading skill, alphanumeric symbol naming speed, nonsymbol naming speed, alphanumeric processing speed, and nonsymbol processing speed. Results were not completely consistent with either the general processing speed or the orthographic processing speed accounts. Although an alphanumeric symbol processing efficiency component is clearly involved, it is argued that the particularly strong association between naming speed and word reading also reflects the efficiency of phonological processing in children of this age.

Perceived dissimilarity and work group involvement: The moderating effects of group openness to diversity

Perceived dissimilarity and its association with work group involvement were examined in this study. Additionally, perceived group openness to diversity was examined as a moderator of this relationship. A longitudinal study was conducted with nurses in four departments of a public hospital. Results revealed that visible dissimilarity was negatively associated with work group involvement at both times, and informational dissimilarity was negatively associated with work group involvement at Time 1. Openness to diversity interacted with visible and informational dissimilarity in the prediction of work group involvement at both times. This interaction pattern showed that there was a negative relationship between dissimilarity and work group involvement when individuals perceived low group openness to diversity, whereas there was no relationship when individuals perceived high group openness to diversity. Results highlight the importance of managing perceptions of difference and introducing norms that encourage the active involvement of group members.

The roles of depression and anxiety in the understanding and treatment of Obstructive Sleep Apnea Syndrome

Obstructive Sleep Apnea Syndrome (OSAS) is a debilitating condition stemming from disruption to the respiratory system during sleep. At present, the nature of the relationship between OSAS and mood, specifically depression and anxiety, is still unclear. The purpose of this paper is to shed some light on this relationship. PsycINFO was used to locate relevant papers on this topic. This literature search formed the basis of our investigation. Results showed that the anxiety and depression methodology is weak. It is now clear that there is an urgent need to better understand the roles of anxiety and depression in OSAS. For example, the research literature suggests that depression and anxiety covary with OSAS. However, because of methodological issues, such as difficulties involved in diagnosis and the use of inappropriate instruments, this conclusion remains tenuous. Future directions are discussed.

Familial influence on offspring gambling: a cognitive mechanism for transmission of gambling behavior in families

Background. The problem-gambling literature has identified a range of individual, cognitive, behavioral and emotional factors as playing important roles in the development, maintenance and treatment of problem gambling. However, familial factors have often been neglected. The current study aims to investigate the possible influence of parental factors on offspring gambling behavior. Method. A total of 189 families (546 individuals) completed several questionnaires including the South Oaks Gambling Screen (SOGS) and the Gambling Related Cognition Scale (GRCS). The relationships were examined using Pearson product-moment correlations and structural equation modeling (SEM) analyses. Results. Results showed that generally parents' (especially fathers') gambling cognitions and gambling behaviors positively correlated with offspring gambling behaviors and cognitions. However, SEM analyses showed that although parental gambling behavior was directly related to offspring gambling behavior, parental cognitions were not related to offspring gambling behavior directly but indirectly via offspring cognitions. Conclusion. The findings show that the influence of parental gambling cognition on offspring gambling behavior is indirect and via offspring cognitions. The results suggest a possible cognitive mechanism of transmission of gambling behavior in the family from one generation to the next.

Desire to drink in low- and high-risk social drinkers: An experimental analogue of impaired control

This study used a novel cue exposure paradigm to investigate the differences between high- and low-risk drinkers in their desire to drink during a drinking session. Fifty-three self-selected participants were assigned to high- or low-risk drinking groups based on their self-reported consumption of alcohol, then compared on their desire to drink over a 90 min paced drinking session. High-risk drinkers showed increasing desire over the session, while low-risk drinkers' desire began to decrease after only a short drinking period. The perceived and actual effects of the alcohol did not appear to be able to account for the difference. Results are discussed with reference to issues of impaired control. Suggestions for future research directions are also offered.

Adolescents' willingness to seek psychological help: Promoting and preventing factors

Although a relatively high percentage of Australian adolescents experience mental health problems, many disturbed adolescents do not receive the help they require, and only a small proportion of adolescents seek professional psychological help. The present study examined adolescents' willingness to seek help and investigated factors that promote and prevent adolescents from seeking help for a mental illness from both formal and informal sources. Secondary school students (254 in number) from schools in Brisbane, Australia completed a questionnaire that examined the relationship between demographic and psychological variables, attitudes toward mental illness, and willingness to seek help for a mental illness. Results suggest that adolescents with greater adaptive functioning, fewer perceived barriers to help seeking, and higher psychological distress were more willing to seek help from formal and informal sources for a mental illness. Greater social support also predicted willingness to seek help from informal sources. Although attitudes toward mental illness did not influence willingness to seek help, less stigmatising attitudes were related to higher knowledge of mental illness, being female, and higher levels of social support. Implications for the present study focus on enhancing the ability of mental health interventions to increase adolescents' willingness to seek psychological help.

The impact of organizational culture and reshaping capabilities on change implementation success: The mediating role of readiness for change

It was hypothesized that employees' perceptions of an organizational culture strong in human relations values and open systems values would be associated with heightened levels of readiness for change which, in turn, would be predictive of change implementation success. Similarly, it was predicted that reshaping capabilities would lead to change implementation success, via its effects on employees' perceptions of readiness for change. Using a temporal research design, these propositions were tested for 67 employees working in a state government department who were about to undergo the implementation of a new end-user computing system in their workplace. Change implementation success was operationalized as user satisfaction and system usage. There was evidence to suggest that employees who perceived strong human relations values in their division at Time 1 reported higher levels of readiness for change at pre-implementation which, in turn, predicted system usage at Time 2. In addition, readiness for change mediated the relationship between reshaping capabilities and system usage. Analyses also revealed that pre-implementation levels of readiness for change exerted a positive main effect on employees' satisfaction with the system's accuracy, user friendliness, and formatting functions at post-implementation. These findings are discussed in terms of their theoretical contribution to the readiness for change literature, and in relation to the practical importance of developing positive change attitudes among employees if change initiatives are to be successful.

Does industry matter? Examining the role of industry structure and organizational learning in innovation and brand performance

A manager's perception of industry structure (dynamism) has the potential to impact various organizational strategies and behaviors. This may be particularly so with regard to perceptions driving organizational learning orientations and innovation based marketing strategy. The position taken here suggests that firms operating within a competitive industry tend to pursue innovative ways of performing value-creating activities, which requires the development of learning capabilities. The results of a study of SMEs suggest that market focused learning, relative to other learning capabilities plays a key role in the relationships between industry structure, innovation and brand performance. The findings also show that market focused learning and internally focused learning influence innovation and that innovation influences a brand's performance. (c) 2005 Elsevier Inc.

The preparation of reach-to-grasp movements in adults, children, and children with movement problems

This study explored the use of advance information in the control of reach-to-grasp movements. The paradigm required participants to reach and grasp illuminated blocks with their right hand. Four target blocks were positioned on a table surface, two each side of the mid-saggital plane. In the complete precue condition, advance information precisely specified target location. In the partial precue condition, advance information indicated target location relative to the midsaggital plane (left or right). In the null condition, the advance information was entirely ambiguous. Participants produced fastest responses in the complete precue condition, intermediate response times in the partial condition, and the slowest responses in the null condition. This result was observed in adults and four groups of children including a group aged 4-6 years. In contrast, children with Developmental Coordination Disorder (DCD, n = 11, aged 7-13 years) showed no advantage of partial precueing. Movement duration was determined by target location but was unaffected by precue condition. Movement duration was a clear function of age apart from children in the DCD group who showed equivalent movement times to those of the youngest children. These findings provide important insights into the control of reach-to-grasp movements and highlight that partial cues are exploited by children as young as 4 years but are not used in situations of abnormal development.

Effects of visual occlusion and fatigue on motor performance in water

The purpose of this study was to test the effects of visual occlusion and fatigue on the motor performance of vertical skills in synchronized swimming. Experienced synchronized swimmers (n = 12) were randomly assigned to either an exercise or nonexercise (control) activity group. Subjective ratings of fatigue were obtained from the swimmers who then each performed four vertical skills under alternating conditions of vision and visual occlusion before and after either a swimming (designed to induce fatigue) or nonphysical activity. A main effect of activity (p < .03) was found for two measures of performance accuracy (lateral and anterior total distance traveled) but not for lateral and anterior maximum deviation from vertical, indicating that fatigue played a role in executing the skills. The data also indicate that the maintenance of a stationary position is a skill of greater difficulty than maintaining a true vertical. In contrast with previous research findings on synchronized swimmers, a significant effect of vision in all conditions was found, with performance decrements in the conditions of visual occlusion showing that vision provided important sensory input for the swimmers.

Thermal biofeedback, locus of control and precompetitive anxiety in young athletes

Small groups of athletes (maximum size 8) were taught to voluntarily control their finger temperature, in a test of the feasibility of thermal biofeedback as a tool for coaches. The objective was to decrease precompetitive anxiety among the 140 young, competitive athletes (track and field, N=61; swimming, N=79), 66 females and 74 males, mean age 14.8 years, age range 8.9-20.5 years, from local high schools and swimming clubs. The biofeedback (visual and auditory) was provided by small, battery-powered devices that were connected to thermistors attached to the middle finger of the dominant hand. An easily readable digital LCD display, in 0.01 degrees C increments, provided visual feedback, while a musical tone, which descended in pitch with increased finger temperature, provided the audio component via small headphones. Eight twenty minute sessions were scheduled, with 48 hours between sessions. The measures employed in this prestest-posttest study were Levenson's locus of control scale (IPC), and the Competitive Sport Anxiety Inventory (CSAI-2). The results indicated that, while significant control of finger temperature was achieved, F(1, 160)=5.30, p

Degrees of freedom and motor planning in purposive movement

This paper presents empirical evidence suggesting that healthy humans can perform a two degree of freedom visuo-motor pursuit tracking task with the same response time delay as a one degree of freedom task. In contrast, the time delay of the response is influenced markedly by the nature of the motor synergy required to produce it. We suggest a conceptual account of this evidence based on adaptive model theory, which combines theories of intermittency from psychology and adaptive optimal control from engineering. The intermittent response planning stage has a fixed period. It possesses multiple optimal trajectory generators such that multiple degrees of freedom can be planned concurrently, without requiring an increase in the planning period. In tasks which require unfamiliar motor synergies, or are deemed to be incompatible, internal adaptive models representing movement dynamics are inaccurate. This means that the actual response which is produced will deviate from the one which is planned. For a given target-response discrepancy, corrective response trajectories of longer duration are planned, consistent with the principle of speed-accuracy trade-off. Compared to familiar or compatible tasks, this results in a longer response time delay and reduced accuracy. From the standpoint of the intermittency approach, the findings of this study help make possible a more integral and predictive account of purposive action. (c) 2005 Elsevier B.V.

A spatial explanation for synchrony biases in perceptual grouping: Consequences for the temporal-binding hypothesis

If two images are shown in rapid sequential order, they are perceived as a single, fused image. Despite this, recent studies have revealed that fundamental perceptual processes are influenced by extremely brief temporal offsets in stimulus presentation. Some researchers have suggested that this is due to the action of a cortical temporal-binding mechanism, which would serve to keep multiple mental representations of one object distinct from those of other objects. There is now gathering evidence that these studies should be reassessed. This article describes evidence for sensitivity to fixational eye and head movements, which provides a purely spatial explanation for the earlier results. Taken in conjunction with other studies, the work serves to undermine the current body of behavioral evidence for a temporal-binding mechanism.
