Pedophilia,Height, and the Magnitude of the Association: A Research Note

Physical height is a manifestation of in utero and childhood conditions, and pedophilic individuals have generally been reported to be of lesser height. Jung, Klaver, and Pham (2014), however, report findings that fail to support an association between pedophilia and height. In the present note, we examine the methodology and findings of Jung et al. To estimate the magnitude of the pedophilia–height association, we conducted a meta-analysis of the published literature and found a significant effect size. Our findings suggest pedophiles may experience conditions during in utero and childhood development that are capable of influencing their physical development.     

Waiting When Both Certainty and Magnitude Are Increasing: Certainty Overshadows Magnitude

In everyday decision making, people often face decisions with outcomes that differ on multiple dimensions. The trade‐off in preferences between magnitude, temporal proximity, and probability of an outcome is a fundamental concern in the decision‐making literature. Yet, their joint effects on behavior in an experience‐based decision‐making task are understudied. Two experiments examined the relative influences of the magnitude and probability of an outcome when both were increasing over a 10‐second delay. A first‐person shooter video game was adapted for this purpose. Experiment 1 showed that participants waited longer to ensure a higher probability of the outcome than to ensure a greater magnitude when experienced separately and together. Experiment 2 provided a precise method of comparing their relative control on waiting by having each increase at different rates. Both experiments revealed a stronger influence of increasing probability than increasing magnitude. The results were more consistent with hyperbolic discounting of probability than with cumulative prospect theory's decision weight function. Copyright © 2014 John Wiley & Sons, Ltd.     

Magnitude of trauma and personality change

In this paper the author postulates that, in post-traumatic personality structures caused by overwhelming traumatic experiences, pre-traumatic personality features and childhood experiences are of little or no relevance. Sixty-four survivors of Nazi concentration camps are examined, their concentration camp experiences detailed and pre-persecution histories and post-persecution psychopathology studied. The significance of a concentration camp experience is analytically discussed and evaluated. This study shows that 52 cases (81.2%) of the 64 survivors of concentration camps presented an almost identical depressive personality structure irrespective of their prepersecution life history. The 64 survivors of concentration camps are psychologically compared to 78 cases of people who, in view of the menacing circumstances, decided to emigrate and in this way were spared from becoming victims of the Nazi 'final solution'. Finally, the author discusses the value of psychoanalytical treatment.

Magnitude estimation of apparent sums and differences

Os first scaled two continua by magnitude estimation: apparent area of circles and loudness of 1,000-Hz tones. They then gave magnitude estimations of apparent sums and apparent differences for IS pairs of stimuli on each of the two continua. The scales for sums and differences were in some cases nearly linearly related to the power function obtained when the same as scaled the underlying continuum. However, systematic departure from linearity was the usual result. The power law exponents obtained were generally smaller than those usually reported for the two sensory continua.     

The Risks,Benefits, and Ethics of Trauma-Focused Research Participation

With the rising interest in the field of trauma research, many Institutional Review Boards, policymakers, parents, and others grapple with the impact of trauma-research participation on research participants' well-being. Do individuals who participate in trauma-focused research risk experiencing lasting negative effects from participation? What are the potential benefits that may be gleaned from participation in this work? How can trauma research studies be designed ethically, minimizing the risk to participants? The following review seeks to answer these questions. This review indicates that most studies in this area have found that only a minority of participants experience distress when participating in trauma-focused research. Furthermore, these negative feelings tend to dissipate quickly over time, with the majority of participants self-appraising their participation as positive, rewarding, and beneficial to society. Design characteristics that may serve to minimize participants' risk of experiencing distress are discussed, as well as implications for public policy and future research.     

数量表征的符号特异性和符号非特异性

数量表征(numerical representation)指与特定数量相联系的心理表征。长期以来抽象的数量表征假说占据主导地位, 但随着自动化加工范式和脑成像技术的发展, 数量表征存在符号特异性的证据已不断涌现。其中, 最近有两个理论认为数量表征可能同时存在符号特异性和符号非特异性。计算的模型假说提出非符号数量和符号数字在总和编码阶段具有符号特异性, 而在之后的位置编码阶段具有符号非特异性。双重编码的延伸假说则认为数量表征在自动编码阶段具有符号特异性, 然后在有意编码阶段, 受任务要求影响, 数量表征向实时的抽象表征过渡。已有大量行为和神经基础研究为以上假说提供了证据, 但数量表征动态变化的内在机制和脑区还有待探索, 未来应该在发展、跨文化、自动加工范式与神经成像相结合、单细胞记录技术等方向继续开展数量表征研究。     

Magnitude estimations of the course of gustatory adaptation

Magnitude estimations of 15-sec intervals were obtained during 2-min and 5-min adaptation of suprathreshold solutions of NaCl. quinine sulfate (QSO₄, and sucrose. Expectorating and adding fresh adapting solution at the end ofeach minute produced higher estimations than those obtained with continuous adaptation because of salivary dilution. Separation of the adaptation determinations by 45-sec rest intervals rather than 5 min had no effect on the form or magnitude of the functions for NaCl or sucrose, although QSO₄. adaptations separated by the shorter rest intervals were of greater magnitude. The absence of complete adaptation was largely attributed to the effects of tongue movements.     

Age Differences in the Magnitude of the Attentional Blink

When people attend to a target in a rapid sequence of items, their perception of a subsequent target is impaired for about 500 ms. This is termed the attentional blink. In the present experiment, a dual task rapid serial presentation task (Raymond, Shapiro & Arnell, 1992) was used as a measure of inhibitory function of younger and older adults. We found that the attentional blink was larger among older adults as compared to younger adults, supporting Hasher and Zacks' (1988) inhibitory deficit hypothesis and current models of the attentional blink.     

符号数量和非符号数量的空间表征:5岁儿童的SNARC效应和距离效应

对物理刺激的数量信息表征是符号数字表征的前提和基础,据此假设在儿童的SNARC效应发生的时序问题上,非符号数量(如面积)的空间表征早于符号数量(如阿拉伯数字)的空间表征。本研究邀请5岁幼儿完成数字比较和面积比较两类任务,结果发现在数字比较任务中没有出现SNARC效应,但却存在距离效应;在面积比较任务中出现了SNARC效应和距离效应。可以推断,在阿拉伯数字的空间表征出现之前,儿童已经能够对非符号数量信息进行空间表征。

Magnitude of negative reinforcement and resistance to extinction

In the first experiment rats experienced large or small magnitude of negative reinforcement (shock reduction) in a straight alley. Half of the subjects in each magnitude group received continuous reinforcement, and the other half received a 50% partial reinforcement schedule (nonreinforcement consisting of no shock reduction in the goal box). In extinction the groups were ordered: large partial > small-partial > small-continuous > large-continuous. In the second experiment rats received large, small and nonreinforcement in various sequences using the runway-negative reinforcement procedure and were ordered: SNL>LNL>SNL>LNS in resistance to extinction (letters represent the magnitudes in the sequence experienced in acquisition). The results of these experiments indicate a commality between positive and negative reinforcement with respect to behavioral phenomena and theoretical accounts of those phenomena.
