Effects of chronic non-clinical depression on the use of positive and negative words in language contexts

The purpose of this study was to investigate the effects of chronic non-clinical depression (ChD) on the use of ambiguous and unambiguous emotional words in language contexts. Participants with ChD and normal non-depressed (ND) participants' responses to positive and negative stimulus words on a free association word test were compared using the Hyperspace Analogue to Language (HAL) model of memory's context density metric, a measure of the range of contexts in which a word is used in language. ChD participants generated negative words that were used in more restricted contexts than ND participants. However, ND and ChD participants used positive words in a similar range of contexts. The results suggest that people with ChD tend to use negative words that are probably more negative in connotation, yet they are not impaired with respect to using words in contexts where positive words are required.     

Learning By Tracing Worked Examples

Cognitive load theorists have only recently begun to test the role of the body in learning. Tracing the index finger over the surface of instructions while reading, an embodied pedagogy based on Montessori's sandpaper letters, may hold substantial promise for learning by reducing cognitive load. Two experiments tested whether students who traced their index fingers against paper‐based worked example instructions in triangle geometry (Experiment 1; N = 52) and order of operations (Experiment 2; N = 54) would perform better on a subsequent test than students who only studied the materials visually. Students in the tracing condition outperformed the non‐tracing condition on transfer problems in both Experiment 1 (d = .78) and Experiment 1 (d = .50), but hypotheses regarding self‐reports of cognitive load during testing were not supported. Implications for research and practice are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

The selective utilization of information in the optic array

Summary When ambulatory subjects wear prisms with bases vertically opposed before the two eyes, the direction of the after-effect measured on a localization task shows that there is a bias favouring selection of the field which contains more of the floor. Subjects allowed differential views of the floor with prism bases laterally opposed also show this bias. The bias is reversed if flow patterns from the lower visual field are eliminated. These studies support the view that information in the lower ambient field is selectively utilized during locomotion.This research was supported by Grant No. APA-1 from the National Research Council of Canada. Experiment 4 and a first replication of Experiment 1 were part of a thesis submitted by the junior author for the M.A. degree at the University of Toronto.     

Visibility of an afterimage in the presence of a second afterimage

Visibility of an afterimage has been measured for a single rectangular bar on its own and in the presence of a second bar. Visibility of each bar is increased if the two bars are in the same orientation and closer than 1 deg (this effect being called “facilitation”) and is decreased if the bars are in different orientations (this effect being called “inhibition”). These interactions also depend on the relative size of the bars. If a pattern of two bars is viewed dichoptically, rivalry between the bars occurs causing a mutual decrease in visibility. The rivalry effect and the orientation-specific effects discussed above are additive in the dichoptic viewing condition. The orientation-specific effects have been likened to those found in other psychophysical studies of angle detection.     

Arbitration: Semi-judicial process or negotiation?

Arbitration is usually described as a semi-judicial, evaluative process, where the parties to a dispute surrender their responsibility for its resolution to a disinterested third party. The arbitrator is expected to listen impartially to the arguments of both sides and, on the basis of the evidence put forward, decide the issue between them. This paper questions the validity of the typical image of arbitration and suggests that a more comprehensive understanding can be developed if it is viewed in the context of different models of negotiation. It is argued that the arbitrator is likely to have at least two contrasting roles: (1) that of manager of the process of concession-convergence, when the issues in dispute are relatively straightforward; and (2) that of joint negotiator with the parties, constructing a framework for a future detailed resolution of the dispute, when the issues are more complex. The parties, on the other hand, are likely to be differentiated according to their previous experience of arbitration. While the more experienced participants may be able to make skilful strategic use of the procedures, the inexperienced are likely to be adversely affected by the evaluative/judicial public image of arbitration.     

Epidemiology and preventive interventions: Parental death in childhood as a case example

Illustrates how standard epidemiologic principles form the knowledge base to justify a preventive intervention for an at-risk population. These principles were applied to a sample of 92 from the population of children aged 8 to 15 at alleged risk for mental health disorders because a parent died. Prior work on this alleged risk population is sparse and flawed. Validly determining the population effect of an alleged risk factor requires assessing the influence of sampling bias. The bias found, underrepresentation of deaths of a mother, did not influence the relations among death of a parent and children's depression and conduct disorder, and the modifiable mediators of risk to be changed by the preventive intervention. The epidemiologic measure of effect indicated that death of a parent is a risk factor for major depression but not for conduct disorder among youth. Families recruited for the preventive intervention by epidemiologic methods (ES families) did not differ significantly from the earlier families on whom the knowledge base was formed. Families referred to the intervention by self or others significantly differed from the ES families in two ways that constituted serious biases. The implications of these biases for prevention were discussed.     

PMS as a Gendered Illness Linked to the Construction and Relational Experience of Hetero-Femininity

The majority of research conducted to date on premenstrual distress has focused on heterosexual women. Drawing on research with lesbian and heterosexual self-defined PMS (premenstrual syndrome) sufferers and their partners, we argue that this negates the role played by hetero-patriarchal constructions of both femininity and premenstrual change in the lived experience of premenstrual distress. Negative constructions of PMS and over-responsibility within the home, commonly found in heterosexual relationships, exacerbate distress and result in women being pathologised premenstrually. Conversely, support and understanding offered by partners, more common in lesbian relationships, reduces guilt and self-pathologisation, allowing women to engage in coping strategies premenstrually, such as taking time out to be alone, or engage self-care. These patterns of relational negotiation of women’s premenstrual change can be contextualised within broader cultural representations of hetero-normativity, which provide the context for gendered roles and coping.     

Wittgenstein on the Place of the Concept “Noticing an Aspect”

Seeing aspects is a dominant theme in Wittgenstein's 1940s writings on philosophy of psychology. Interpreters disagree about what Wittgenstein was trying to do in these discussions. I argue that interpreting Wittgenstein's observations about the interrelations between “noticing an aspect” and other psychological concepts as a systematic theory of aspect‐seeing diminishes key lessons of Wittgenstein's explorations: these interrelations are enormously complicated and “noticing an aspect” resists neat classification. Further, Wittgenstein invites us to engage in his “placing activity,” and by doing so we are building a skill that is valuable for enabling us to help ourselves when we encounter conceptual difficulties.     

The utility of the Kessler Screening Scale for Psychological Distress (K6) in two American Indian communities

The Kessler Screening Scale for Psychological Distress (K6; Kessler et al., 2002) has been used widely as a screener for mental health problems and as a measure of severity of impact of mental health problems. However, the applicability and utility of this measure for assessments within American Indian communities has not been explored. Data were drawn from a large-scale epidemiological study conducted in cooperation with 2 American Indian populations. Participants (N = 3,084) were 15-54 years of age and living on or near their home reservations; each completed an interview that included a version of the Composite International Diagnostic Interview (Robins, Wing, Wittchen, & Helzer, 1988) and the K6. A measure of both physical- and mental-health-related quality of life-the Medical Outcome Study's Short Form-36 (Ware & Sherbourne, 1992)-was used to examine the importance of the K6 over and above psychiatric diagnoses. The K6 was shown to be an appropriate screening and severity measure for mood disorders in these 2 samples. It also predicted health-related quality of life over and above that predicted by diagnoses alone. Inclusion of a measure such as the K6 as a complement to more traditional dichotomous diagnoses in both research and clinical practice is recommended.     

Children reorient using the left/right sense of coloured landmarks at 18-24 months

In previous studies, children disoriented in small enclosures used room shape, but not wall colours, to find hidden objects. Their reorientation was said to depend solely on a "geometric module" informationally encapsulated with respect to colour. We argue that previous studies did not fully evaluate children's use of colour owing to a bias in the enclosures' design. In this study, disoriented 18-24 month olds searched for toys in small square enclosures with two blue and two white walls. Children successfully reoriented using wall colour. This shows that they can make location judgments based on the left/right sense of the colours of adjoining landmarks. Performance was no different when symmetric colourful shapes were added to walls, but improved with asymmetric shapes which could be used without left/right judgments. The relatively poor use of colour in previous studies may be explained partly by a bias in their design, and partly by children's limited ability to discriminate the left/right sense of nongeometric features.
