The Relation Between Compulsive Sexual Behaviors and Aggression in a Substance-Dependent Population

Research supports a high comorbidity between compulsive sexual behaviors (CSBs) and substance use disorders (SUDs), which are both classified by increased impulsivity. Literature has also indicated that increased impulsivity and substance use are associated with aggression. However, no known research has examined the relationship between CSBs and aggression among a substance-dependent population. The purpose of this study was to examine this relationship. Participants included 349 male patients in treatment for SUDs. Results indicated that after controlling for alcohol and drug use and problems and age, CSBs were significantly associated with total aggression, aggressive attitudes, physical aggression, and verbal aggression. This is the first known study to examine this relationship; thus continued research is needed to extend and replicate these findings.     

In Search of the ‘Angels of Death’: Conceptualising the Contemporary Nurse Healthcare Serial Killer

Focusing specifically upon nurses who commit serial murder within a hospital setting, this paper aims to establish insights into this particular subcategory of healthcare serial killer. In addition, the paper aims to test the usefulness of an existing checklist of behaviours among this group of serial murderers. Drawing upon existing lists of healthcare serial killers produced by other scholars as well as legal records and an online news archive, we identified and researched healthcare serial killer nurses, collating socio demographic and criminological data and applying the aforementioned checklist to each case. Our findings suggest that to date, the label ‘healthcare serial killer’ has been applied in too loose a manner, making the understanding of this phenomenon problematic. In further refining the definition and identifying the socio‐demographic and criminological characteristics of the victims, perpetrators and crimes, we have developed more specific and therefore useful insights for practitioners and identified a potentially useful checklist which, with revisions, could contribute towards preventative strategies and interventions.

Tactile order memory: evidence for sequence learning phenomena found with other stimulus types

We examine serial order memory for sequences of tactile stimuli and investigate whether established characteristics of order memory, namely serial position effects, error distributions, and Hebb repetition learning, are observed with tactile memory. Visually obscured participants received six tactile stimulations: one to each of six fingers. At test, participants lifted the six fingers in the order of stimulation. For every third trial participants received the same order of stimulation (i.e. the Hebb sequence). Serial recall accuracy produced the canonical bowed serial position function found for immediate serial recall. In addition, recall for the Hebb sequence improved relative to the filler sequences, providing the first demonstration of the Hebb repetition effect with tactile stimuli. Analysis of errors revealed close similarities to that reported with verbal and visual stimuli. This experiment further generalises established features of order memory to tactile memory, supporting the utilisation of an analogous order memory mechanism across stimuli.     

初中生羞怯与手机依赖的关系:一个有调节的中介模型

为探讨初中生羞怯、疏离感、班级心理环境和手机依赖的关系,采用羞怯量表、青少年疏离感量表、班级心理环境量表和手机依赖指数量表对山东省两所学校的1077名初一至初三年级的学生进行调查。结果显示：（1）羞怯显著正向预测初中生手机依赖;（2）疏离感在初中生羞怯与手机依赖之间起完全中介作用;（3）班级心理环境对中介效应的后半段路径起调节作用,高班级心理环境会缓解疏离感对手机依赖的影响,但在极高疏离感水平下,高班级心理环境反而会加剧个体的手机依赖水平。研究有助于了解羞怯对手机依赖的复杂影响机制,对预防以及减少初中生手机依赖具有一定的现实意义。     

Part-set cueing impairment & facilitation in semantic memory

The present study explored the influence of part-set cues in semantic memory using tests of “free” recall, reconstruction of order, and serial recall. Nine distinct categories of information were used (e.g., Zodiac signs, Harry Potter books, Star Wars films, planets). The results showed part-set cueing impairment for all three “free” recall sets, whereas part-set cueing facilitation was evident for five of the six ordered sets. Generally, the present results parallel those often observed across episodic tasks, which could indicate that similar mechanisms contribute to part-set cueing effects in both episodic and semantic memory. A novel anchoring explanation of part-set cueing facilitation in order and spatial tasks is provided.     

The Repeatability Argument and the Non-Extensional Bundle Theory

I present a new objection to Bundle Theory. The objection rests on the repeatability of universals, and targets every version of Bundle Theory that assumes that concrete particulars constituted by the same universals are numerically identical. The only way that bundle theorists can elude this objection is to admit the possibility of distinct bundles constituted by the same universals. If even this view is untenable, then Bundle Theory as such is hopeless. Finally, I show how the present inquiry reshapes the dialectical relationship between Bundle Theory and the principle of Identity of Indiscernibles.     

Age-related differences in sequence learning: Findings from two visuo-motor sequence learning tasks

The Serial Reaction Time Task (SRTT) is thought to assess implicit learning, which seems to be preserved with age. However, the reaction time (RT) measures employed on implicit-like tasks might be too unreliable to detect individual differences. We investigated whether RT-based measures mask age effects by comparing the performance of 43 younger and 35 older adults on SRTT and an explicit-like Predictive Sequence Learning Task (PSLT). RT-based measures (difference scores and a ratio) were collected for both tasks, and accuracy was additionally measured for PSLT. We also measured fluid abilities. The RT-difference scores indicated preserved SRTT and PSLT performance with age and did not correlate with fluid abilities, while ratio RT and the accuracy-based measures indicated age-related decline and correlated with fluid abilities. Therefore, RT-difference scores might mask individual differences, which compromises the interpretation of previous studies using SRTT.     

Independent effects of word concreteness and word valence on immediate serial recall

The present study examined the roles of word concreteness and word valence in the immediate serial recall task. Emotion words (e.g. happy) were used to investigate these effects. Participants completed study-test trials with 7-item study lists consisting of positive or negative words with either high or low concreteness (Experiments 1 and 2) and neutral (i.e. non-emotion) words with either high or low concreteness (Experiment 2). In serial recall performance, we replicated the typical item concreteness effect (concrete words are better recalled than abstract words) and obtained an item valence effect (positive/neutral words are better recalled than negative words). However, there was no concreteness × valence interaction. We conclude that both word valence and word concreteness independently contribute to the serial order retention of emotion words in the immediate serial recall task.     

从父母教育卷入到学业成就:自主支持与自主学习力的链式中介

家长教育卷入是为了提升学生的学业成就,但能否支持学生的自主学习从而提升其自主学习力,可能是提升学业成就的关键环节。研究将与自主学习相关的多种个人内部因素整合为自主学习力,对12万余名中小学生及其家长进行了大规模调查,建构了一个链式中介模型,分析显示父母教育卷入对学生学业成就的影响体现为两条路径:(1)父母主导路径:父母投入通过其自我报告的自主支持对学生学业成就产生显著影响;(2)学生发展路径:学生通过其所感知的父母自主支持提升其自主学习力,进而自主地促进其学业发展。研究提示,如何提高家长对学生“自主学习”的认识和支持能力,是家校协同促进学业发展的一个重要话题,也是保障“双减”不降学业成绩的一项关键举措。     

学校归属感与青少年手机依赖的关系:学习焦虑的中介效应与同伴关系的调节效应

为探讨学校归属感对青少年手机依赖的影响及其作用机制,基于阶段环境匹配理论,本研究采用问卷法对山东省青岛市65所中学3355名高二年级学生进行调查。结果表明:(1)在控制了性别和上网时间后,学校归属感对青少年手机依赖具有显著的负向预测作用;(2)学习焦虑在学校归属感与青少年手机依赖之间起部分中介作用;(3)学校归属感对青少年手机依赖的直接作用、学习焦虑的中介作用均受到同伴关系的调节,且相对于同伴关系水平低的个体,学校归属感对手机依赖、学校归属感对学习焦虑以及学习焦虑对手机依赖的作用都在同伴关系水平高的个体中更强。本研究有利于揭示学校归属感是如何影响青少年手机依赖的,以及在何种条件下对青少年手机依赖的影响更强/更弱,对移动互联网时代预防青少年手机依赖有一定启示意义。
