Does violence beget violence? A critical examination of the literature

Critically examines the "violence breeds violence" hypothesis broadly defined. Organized into seven sections, the literature review includes (a) the abuse breeds abuse hypothesis; (b) reports of small numbers of violent/homicidal offenders; (c) studies examining the relationship of abuse and neglect to delinquency, (d) to violent behavior, and (e) to aggressive behavior in infants and young children; (f) abuse, withdrawal, and self-destructive behavior; and (g) studies of the impact of witnessing or observing violent behavior. A detailed discussion of methodological considerations and shortcomings precedes the review. The author concludes that existing knowledge of the long-term consequences of abusive home environments is limited and suggests that conclusions about the strength of the cycle of violence be tempered by the dearth of convincing empirical evidence. Recommendations are made for further research.     

Are the laws of physics ‘economical with the truth’?

It has been argued that the fundamental laws of physics are deceitful in that they give the impression of greater unity and coherence in our theories than is actually found to be the case. Causal stories and phenomenological relationships are claimed to provide a more acceptable account of the world, and only theoretical entities — not laws — are considered as perhaps corresponding to real features of the world.This paper examines these claims in the light of the author's own field of research: high energy physics. Some of the distinctions upon which the above conclusions are based are found not to be tenable in practice. Examples from experimental particle physics are presented which suggest an important role of the underlying theoretical structure which cannot be overlooked. It is argued that the fundamental theories must, in fact, be treated as being as worthy or unworthy of ontological commitment as the entities they postulate or the phenomenological relationships they inspire. Whilst it is conceded that aspects of the current theoretical formalism belie literal interpretation, it is maintained that revision in these particular areas need not affect the symmetry principles, particle spectra, or coupling strengths that largely determine the empirical content of the theory.Various other reasons for believing that the laws of physics may be dishonest are examined and in particular attention is drawn to the current tendency in particle physics to judge a theory's merits by aesthetic criteria. The difficulty of providing a sound justification for this behaviour does lead to the suspicion that our abstract representation of the world may in fact be coloured by anthropomorphic prejudices. The question then remains as to whether this merely points to a certain embellishment of the truth or the masquerading of a lie.I would like to thank my colleagues in high energy physics for their comments on this paper, and I am also particularly indebted to members of the Department of History and Philosophy of Science at Cambridge University for many fruitful discussions on these and related topics. I have benefitted over many years from stimulating philosophical arguments with my friend Alan Birchall, of the NRPB. I would like to dedicate this paper to the memory of John Bell, who had arranged to meet with me at CERN to discuss some of these topics shortly before his tragic death. He was an inspiration to many of us in high energy physics, with interests in the wider issues raised by our subject, and he will be greatly missed.     

Are True Scores and Construct Scores the Same? A critical examination of their substitutability and the implications for research results

Relations between constructs are estimated based on correlations between measures of constructs corrected for measurement error. This process assumes that the true scores on the measure are linearly related to construct scores, an assumption that may not hold. We examined the extent to which differences in distribution shape reduce the correlation between true scores on a measure and scores on the underlying construct they are intended to measure. We found, via a series of Monte Carlo simulations, that when the actual construct distribution is normal, nonnormal distributions of true scores caused this correlation to drop by an average of only .02 across 15 conditions. When both construct and true score distributions assumed different combinations of nonnormal distributions, the average correlation was reduced by .05 across 375 conditions. We conclude that theory‐based scales intended to measure constructs usually correlate highly with the constructs they are constructed to measure. We show that, as a result, in most cases true score correlations only modestly underestimate correlations between different constructs. However, in cases in which the two constructs are redundant, this underestimation can lead to the false conclusion that the constructs are ‘correlated but distinct constructs,’ resulting in construct proliferation.     

Are religious ‘nones’ secular? The case of the nones in Australia

The number of people with no religious affiliation (religious ‘nones’) is growing in the west. However, little is known about the religiosity – or non-religiosity – of these people. Using representative survey data, this report examines the levels of religious belief and practice among Australian religious nones and compares this with those who identify with a religion. It is found that there is a deep congruence with no religious affiliation and other ways of being considered non-religious.     

Depression as a proxy of negative affect? A critical examination of the use of the CES-D in type 2 diabetes

ObjectivesRecent research suggests depression as measured by self-endorsed symptoms lists is associated with poor health outcomes in chronic illness. Yet, it is probable that these lists of symptoms reflect other concepts such as general distress or negative affect when used as dimensions.MethodsTo test for this hypothesis, we explored associations of the Centre of Epidemiological Studies-Depression, Radloff ([CES-D], 1977) with disease severity in diabetes and how trait negative affect from the Profile of Mood States ([POMS]; Usala & Hertzog, 1989; adaptation by Cohen et al., 1995) impact these associations in a sample of 502 people with type 2 diabetes.ResultsWe found that the CES-D included two dimensions of negative and positive experience. Each CES-D component was independently linked to disease severity. However, controlling for trait negative affect suppressed the correlation between the CES-D negative experience component and disease severity. Item-level analyses revealed that the negative experience component of the CES-D bore an emotional tone of sadness but not anger.ConclusionsWhen using the CES-D, distinguishing positive and negative components is necessary. Self-reported depression symptoms from the CES-D have no incremental validity over negative affect.     

What about the babies? A critical review of infants’ and toddlers’ absence in homelessness scholarship

Rates of family homelessness continue to reach unprecedented levels. As many as two million young children experience family homelessness each year, with an estimated one in 10 younger than one year old. Yet, despite their high prevalence, a dearth of studies have specifically investigated infants’ and toddlers’ experiences of homelessness. Overall, the available literature suggests homeless infants and toddlers experience increased risk to physical health, development, and well-being at an individual- and family-level. This presents a severely limited understanding of homeless infants’ and toddlers’ experiences, with substantial gaps remaining. This review documents the scant existing literature on infant and toddler development within the context of homelessness at both the individual and family-system levels, and proposes next steps for research, practice, and policy.     

Does religious belief promote prosociality? A critical examination

Numerous authors have suggested that religious belief has a positive association, possibly causal, with prosocial behavior. This article critiques evidence regarding this "religious prosociality" hypothesis from several areas of the literature. The extant literature on religious prosociality is reviewed including domains of charity, volunteering, morality, personality, and well-being. The experimental and quasi-experimental literature regarding controlled prosocial interactions (e.g., sharing and generosity) is reviewed and contrasted with results from naturalistic studies. Conceptual problems in the interpretation of this literature include separating the effects of stereotypes and ingroup biases from impression formation as well as controlling for self-report biases in the measurement of religious prosociality. Many effects attributed to religious processes can be explained in terms of general nonreligious psychological effects. Methodological problems that limit the interpretation of religious prosociality studies include the use of inappropriate comparison groups and the presence of criterion contamination in measures yielding misleading conclusions. Specifically, it is common practice to compare high levels of religiosity with "low religiosity" (e.g., the absence of denominational membership, lack of church attendance, or the low importance of religion), which conflates indifferent or uncommitted believers with the completely nonreligious. Finally, aspects of religious stereotype endorsement and ingroup bias can contribute to nonprosocial effects. These factors necessitate a revision of the religious prosociality hypothesis and suggest that future research should incorporate more stringent controls in order to reach less ambiguous conclusions.

The ‘I’ and the ‘Me’ in self-referential awareness: a neurocognitive hypothesis

The nature of the ‘self’ and self-referential awareness has been one of the most debated issues in philosophy, psychology and cognitive neuroscience. Understanding the neurocognitive bases of self-related representation and processing is also crucial to research on the neural correlates of consciousness. The distinction between an ‘I’, corresponding to a subjective sense of the self as a thinker and causal agent, and a ‘Me’, as the objective sense of the self with the unique and identifiable features constituting one’s self-image or self-concept, suggested by William James, has been re-elaborated by authors from different theoretical perspectives. In this article, empirical studies and theories about the ‘I’ and the ‘Me’ in cognition and self-related awareness are reviewed, including the relationships between self and perception, self and memory, the development of the self, self-referential stimulus processing, as well as related neuroimaging studies. Subsequently, the relations between self and different aspects of consciousness are considered. On the basis of the reviewed literature and with reference to Block’s distinction between phenomenal and access consciousness, a neurocognitive hypothesis is formulated about ‘I’-related and ‘Me’-related self-referential awareness. This hypothesis is extended to metacognitive awareness and a form of non-transitive consciousness, characteristic of meditation experiences and studies, with particular reference to the notion of mindfulness and other Buddhist constructs.     

Are people changed by the experience of having an episode of depression? A further test of the scar hypothesis

The purpose of this study was to identify characteristics of individuals before and after their first depressive episode. Subjects were 49 older persons assessed before and after their first depressive episode on depression-related psychosocial variables. The control group consisted of 351 never-depressed individuals. Consistent with previous findings, patients were more likely to be younger, female, and mildly depressed both before and after the episode. In addition, they were more likely to be employed. Following an episode of depression, the recovered patients described their social skills and health as poorer and their interpersonal dependency as greater than the controls. However, on an experiment-wise basis, the number of significant differences were no greater than expected by chance. The stress activation model was examined but did not appreciably enhance the results. Results suggest that most of the psychosocial variables associated with depression are state dependent.     

Are there critical bands in kinesthesia?

The effect of changing the bandwidth of noise on the ability of human subjects to detect a 10-Hz sinusoidal movement signal was measured in two experiments. The objective of these studies was to investigate whether critical bands exist for the kinesthetic system, as has been demonstrated for the auditory and tactile systems. It was found that subjects' ability to detect a 10-Hz sinusoidal movement stimulus embedded in noise was not influenced by the bandwidth of the noise over a range of 4-10 Hz. These findings suggest that, if a critical filter does exist for this system, it would have to be greater than 10 Hz.     

The three-systems-model of fear and emotion—A critical examination

The ‘Three-Systems-Model’ of fear and emotion (Lang, 1968; Rachman. 1978b) is reviewed and discussed. The paper is centered on four topics relevant to such a view of fear; The definitional focus; Measurement and quantification of components; Implications for etiology; Implications for treatment of phobias. Definitional problems with the radical operationalist view implied by the Tree-Systems-Model are identified and discussed. In addition problems with measurement and quantification of the various components are discussed. Implications for etiology of phobic fears are noted. Finally, it is suggested that treatment methods be individually tailored to the particular component response-profile displayed by each patient, and that the identification of such a profile is included in standard behavioral diagnosis procedures when fear is clinically assessed.     

‘Defending the family,’ safeguarding the nation: an examination of evangelical mobilisation in present-day Barbados

This article addresses the connection between religion, culture and the family through a critical examination of evangelical Christians’ focus on ‘the family’ in Barbados, in 2015 and 2016. The intentions are to highlight Evangelical Christians’ strategic deployment of a common rhetoric or frame of ‘defending the family,’ which was put forward in public discourses relating to sex, sexuality, marriage and the family. This rhetoric draws upon and reproduces deep-seated anxieties around the state of the family as well as its connection to ideas of progress, freedoms, national sovereignty and the establishment of strong nations. The article also sheds sociological light on Evangelical mobilisations by exploring the socio-cultural context in which they are occurring. The presented analysis is based on a critical feminist discourse analysis of relevant local and regional newspaper articles, blogs and websites, observational research as well as a review of secondary qualitative and quantitative data and pre-existing scholarly literature.     

A neuronal retuning hypothesis of sentence-specificity in Broca’s area

It is clear that the left inferior frontal gyrus (LIFG) contributes in some fashion to sentence processing. While neuroimaging and neuropsychological evidence support a domain-general working memory function, recent neuroimaging data show that particular subregions of the LIFG, particularly the pars triangularis (pTri), show selective activation for sentences relative to verbal working memory and cognitive control tasks. These data suggest a language-specific function rather than a domain-general one. To resolve this apparent conflict, I propose separating claims of domain-generality and specificity independently for computations and representations—a given brain region may respond to a specific representation while performing a general computation over that representation, one shared with other systems. I hypothesize that the pTri underlies a language-specific working memory system, comprised of general memory retrieval/attention operations specialized for syntactic representations. There is a parallelism of top-down retrieval function among the phonological and semantic levels, localized to the pars opercularis and pars orbitalis, respectively. I further explore the idea of how such a system emerges in the human brain through the framework of neuronal retuning: the “borrowing” of domain-general mechanisms for language, either in evolution or development. The empirical data appear to tentatively support a developmental account of language-specificity in the pTri, possibly through connections to the posterior superior temporal sulcus (pSTS), a region that is both anatomically distinct for humans and functionally essential for language. Evidence of representational response specificity obtained from neuroimaging studies is useful in understanding how cognition is implemented in the brain. However, understanding the shared computations across domains and neural systems is necessary for a fuller understanding of this problem, providing potential answers to questions of how specialized systems, such as language, are implemented in the brain.     

A problem for Wegner and colleagues’ model of the sense of agency

The sense of agency, that is the sense that one is the agent of one’s bodily actions, is one component of our self-consciousness. Recently, Wegner and colleagues have developed a model of the causal history of this sense. Their model takes it that the sense of agency is elicited for an action when one infers that one or other of one’s mental states caused that action. In their terms, the sense of agency is elicited by the inference to apparent mental state causation. Here, I argue that this model is inconsistent with data from developmental psychology that suggests children can identify the agent behind an action without being capable of understanding the relationship between their intentions and actions. Furthermore, I argue that this model is inconsistent with the preserved sense of agency in autism. In general, the problem is that there are cases where subjects can experience themselves as the agent behind their actions despite lacking the resources to make the inference to apparent mental state causation.     

The snake in the mandala: dialogical aspects of Jung’s ‘A study in the process of individuation’

Jung’s study centres on the amplification of pictures painted by a woman patient and posits their sequence as evincing the initial stages of the individuation process. His text performs a dialogue with its audience whereby Jung persuades us of this truth, and also reveals Jung’s dialogue with his patient and with his own ideas. The present paper revisits the clinical material first with a focus on the interaction between Jung and his patient. The second part compares the 1940 and 1950 versions of Jung’s study with attention to tensions that traverse them, such as Jung’s attitude to the animus and his two voices as a practitioner and a theorist.     

Are the spoken durations of rare words longer than those of common words?

The effects of word frequency, word length, and practice were examined in oral productions of subjects reading lists of 25 rare or common monosyllabic words. Articulation and pause durations, their ratio, and total reading durations were derived from recordings of subjects’ speech. Recorded speech was sampled at 10 kHz, and a criterion of eight times the mean noise level was used to classify productions as articulation or pause. Lists of high frequency words were read more quickly than lists of low-frequency words. No differences were observed in the articulation component. Pause duration was greater for rare than for common words. The ratio of pause to articulation varied with length and word type. No differences were found for high-frequency words, but the ratio of five-letter words was significantly greater than that of three- or four-letter rare words. Results were discussed in relation to the nature and locus of the word-frequency effect. Criteria for defining and measuring speech productions were also raised.
