Sadistic personality disorder (SPD) has been underresearched and often misunderstood in forensic settings. Furthermore, personality disorders in general are the subject of much controversy in terms of their classification (i.e., whether they should be categorical or dimensional). The Sadistic Attitudes and Behaviors Scale (SABS; Davies & Hand, 2003; O'Meara, Davies, & Barnes-Holmes, 2004) is a recently developed scale for measuring sadistic inclinations. Derived from this is the Short Sadistic Impulse Scale (SSIS), which has proved to be a strong unidimensional measure of sadistic inclination. Through cumulative scaling, it was investigated whether the SSIS could measure sadism on a continuum of interest, thus providing a dimensional view of the construct. Further, the SSIS was administered along with a number of other measures related to sadism in order to assess the validity of the scale. Results showed that the SSIS has strong construct and discriminant validity and may be useful as a screening measure for sadistic impulse. 相似文献

We examine the extent to which retrieval from very long-term autobiographical memory is similar when participants are asked
to retrieve from widely differing periods of time. Three groups of 20 participants were given 4 min to recall autobiographical
events from the last 5 weeks, 5 months, or 5 years. Following recall, the participants dated their events. Similar retrieval
rates, relative recency effects, and relative lag-recency effects were found, despite the fact that the considered time scales
varied by a factor of 52. These data are broadly consistent with the principle of recency, the principle of contiguity (Howard
& Kahana, 2002), and scale similarity in the rates of recall (Brown, Neath, & Chater, 2007; Maylor, Chater, & Brown, 2001).
These findings are taken as support for models of memory that predict time scale similarity in retrieval, such as SIMPLE (Brown
et al., 2007) and TCM (Howard & Kahana, 2002). 相似文献

The presentation of a stimulus below the threshold of conscious awareness can exert an influence on the processing of a subsequent target. One such consequence of briefly presented “primes” is seen in the negative compatibility effect. The response time (RT) to determine the left—right orientation of an arrow (i.e., the target) is relatively slow if a prime is also an arrow whose direction corresponds to that of the target. When the direction of the arrow is opposite that of the prime, RTs are relatively fast. In four experiments, we examined whether the prime shifts attention from the location of the subsequent target and whether this attention shift influences target processing. Results showed that the prime does indeed move attention. The consequence of this attention movement is that the representation of direction is affected. Specifically, RTs to process an arrow are shorter if the arrow’s direction is compatible with the last shift of attention. Furthermore, this interference occurs at a conceptual level concerning the representation of left and right rather than at the motor planning level. We argue that a shift in attention brought about by the prime can create a negative compatibility-like effect. 相似文献

ABSTRACT— Replication is fundamental to science, so statistical analysis should give information about replication. Because p values dominate statistical analysis in psychology, it is important to ask what p says about replication. The answer to this question is "Surprisingly little." In one simulation of 25 repetitions of a typical experiment, p varied from <.001 to .76, thus illustrating that p is a very unreliable measure. This article shows that, if an initial experiment results in two-tailed p = .05, there is an 80% chance the one-tailed p value from a replication will fall in the interval (.00008, .44), a 10% chance that p < .00008, and fully a 10% chance that p > .44. Remarkably, the interval—termed a p interval —is this wide however large the sample size. p is so unreliable and gives such dramatically vague information that it is a poor basis for inference. Confidence intervals, however, give much better information about replication. Researchers should minimize the role of p by using confidence intervals and model-fitting techniques and by adopting meta-analytic thinking. 相似文献

When comparing two target elements placed on the same convoluted curve, response times are dependent on the distance between the targets along the curve, despite being separated by a constant Euclidean distance. The present study assessed whether such line tracing is obligatory across the whole of the line even when the task demands do not require it, or whether it is an optional strategy that can be disregarded when the circumstances favor a different method of attentional deployment. Three experiments were conducted to assess whether attention can select only a portion of a curve to trace when it is strategically sensible to do so. The results suggest that attention can indeed jump over portions of a line that are irrelevant to task performance before tracing has begun. However, the final experiment suggests that line tracing may continue beyond the task-relevant portion of the line. We conclude that line tracing is a strategy whose initial deployment can be influenced by top-down factors, rather than an obligatory response triggered by the stimuli-although, once engaged, line tracing may be hard to stop. 相似文献

Forgiveness research has focused almost exclusively on interpersonal transgressions committed in close relationships. Consequently, less is known about factors informing forgiveness of non-intimate actors. The current study addresses these gaps by investigating correlates of forgiveness over racial discrimination among African American men (N?=?171). Specifically, we explore relationships between the endorsement of traditional masculine ideology (e.g., restrictive emotionality), overall forgiveness, forgiveness with positive affect, and forgiveness with the absence of negative affect. Links between personality, religiosity, social support, discrimination experiences, and these forms of forgiveness also are examined. Restrictive emotionality emerged as a barrier to forgiveness of discrimination. However, the relationship between restrictive emotionality and forgiveness was moderated by age, socioeconomic status, personality, and religious coping disposition. 相似文献

Many studies have shown that distributions of the distances that offenders travel in the commission of their offences are typically characterised by a decay function. However, there are few empirical comparisons of the different mathematical functions which may characterise such distributions. Further, there has been little consideration of what different forms of function may reflect about the underlying factors and psychological processes governing this aspect of the journey to crime. With the increasing use of geographical profiling systems which incorporate decay functions into their calculations, it is particularly of value to explore the most appropriate mathematics for describing the frequencies of crime journeys and to determine the impact of different decay functions on the effectiveness of a geographical profiling system. A two‐stage study was therefore carried out using data derived from 96 US serial killers. In the first stage three different decay functions were examined, in terms of the extent to which they fitted a distribution of the distances travelled to offend for the sample; logarithmic, in accordance with Steven's ‘Power Law’ for distance estimation; negative exponential as an estimate based on the ‘friction’ generated by journeys; and quadratic, which reflects key principles found from journey to crime research. A ‘control’ function, simple negative linear, was also tested against the data. It was found the logarithmic function provided the closest approximation to the journey to crime distances of offenders in the present sample (R2 = 0.81, p < 0.001), suggesting that distance estimations may be an important part of the explanation for the length of the crime trips that offenders make. In the second stage, all four functions were utilised within a geographical profiling system (Dragnet) and their impact on the search cost for locating an offender established for the whole sample. In general it was found that the search cost function, which relates the proportion of the sample to the search cost, was positively monotonic with a distinct change in gradients around 58% of the sample, indicating that the software was producing useful results in the majority of cases. However, although the logarithmic function produced the best results overall, and the linear function the worst, as hypothesised, no significant differences between the search costs were found when each of the different functions was utilised. The implications for the robustness of the software and the possible influence of the low precision of the raw data are discussed. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

We examined whether the onset of a new object defined by illusory contours is detected with greater frequency than offset
when neither is associated with a unique sensory transient. Observers performed a “one-shot” change detection task in which
offsetting or onsetting elements of high luminance contrast circles generated the appearance or disappearance of a Kanizsa
figure. Presenting “illusory figures” via this “flicker” method ensures that (1) any unique luminance transients associated
with the two types of change are eliminated, and (2) the objects themselves can only be represented at a relatively high level.
Results showed that offsets were detected more frequently than onsets only when they generated the onset of a Kanizsa figure.
We argue that object appearance dominates object disappearance via mechanisms that operate at the level at which objects are
constructed. 相似文献

The epistemic-teleologic model of deliberate self-persuasion. 总被引:1,自引:0,他引:1
Although past theory and research point to the importance of understanding deliberate self-persuasion (i.e., deliberate self-induced attitude change), there have been no empirical and theoretical efforts to model this process. This article proposes a new model to help understand the process, while comparing the process of deliberate self-persuasion with relevant theory and research. The core feature of this model is a distinction between epistemic processes, which involve attempting to form new valid attitudes, and teleologic processes, which involve self-induced attitude change but with minimal concerns for validity. The epistemic processes employ tactics of reinterpretation, reattribution, reintegration, retesting, changing comparators, and changing dimensions of comparison. The teleologic processes include suppression, preemption, distraction, and concentration. By mapping these processes, this model helps to generate many novel and testable hypotheses about the use of deliberate self-persuasion to cope with ambivalent attitudes. 相似文献

In five experiments, rehearsal and recall phenomena were examined using the free recall and immediate serial recall (ISR)
tasks. In Experiment 1, participants were presented with lists of eight words, were precued or postcued to respond using free
recall or ISR, and rehearsed out loud during presentation. The patterns of rehearsal were similar in all the conditions, and
there was little difference between recall in the precued and postcued conditions. In Experiment 2, both free recall and ISR
were sensitive to word length and presentation rate and showed similar patterns of rehearsal. In Experiment 3, both tasks
were sensitive to word length and articulatory suppression. The word length effects generalized to 6-item (Experiment 4) and
12-item (Experiment 5) lists. These findings suggest that the two tasks are underpinned by highly similar rehearsal and recall
processes. 相似文献
