Working memory and intelligence: the same or different constructs?

Several investigators have claimed over the past decade that working memory (WM) and general intelligence (g) are identical, or nearly identical, constructs, from an individual-differences perspective. Although memory measures are commonly included in intelligence tests, and memory abilities are included in theories of intelligence, the identity between WM and intelligence has not been evaluated comprehensively. The authors conducted a meta-analysis of 86 samples that relate WM to intelligence. The average correlation between true-score estimates of WM and g is substantially less than unity (p=.479). The authors also focus on the distinction between short-term memory and WM with respect to intelligence with a supplemental meta-analysis. The authors discuss how consideration of psychometric and theoretical perspectives better informs the discussion of WM-intelligence relations.     

Specificity and detail in autobiographical memory: Same or different constructs?

Research on autobiographical memory has focused on whether memories are coded as specific (i.e., describe a single event that happened at a particular time and place). Although some theory and research suggests that the amount of detail in autobiographical memories reflects a similar underlying construct as memory specificity, past research has not investigated whether these variables converge. Therefore, the present study compared the proportion of specific memories and the amount of detail embedded in memory responses to cue words. Results demonstrated that memory detail and proportion of specific memories were not correlated with each other and showed different patterns of association with other conceptually relevant variables. When responses to neutral cue words were examined in multiple linear and logistic regression analyses, the proportion of specific memories uniquely predicted less depressive symptoms, low emotional avoidance, lower emotion reactivity, better executive control and lower rumination, whereas the amount of memory detail uniquely predicted the presence of depression diagnosis, as well as greater depressive symptoms, subjective stress, emotion reactivity and rumination. Findings suggest that the ability to retrieve specific memories and the tendency to retrieve detailed personal memories reflect different constructs that have different implications in the development of emotional distress.     

Optimism and pessimism in the context of health: bipolar opposites or separate constructs?

One difficulty plaguing research on dispositional optimism and health is whether optimism and pessimism are bipolar opposites or constitute distinct constructs. The present study examined the Life Orientation Test to determine whether the two-factor structure is explained by method bias (due to measurement) or substantive differences. The authors compared three measurement models: bipolar, bivariate, and method artifact. Optimism and pessimism emerged as distinct constructs due to substantive differences. The authors also considered the validity of optimism and pessimism, examining their relations with psychological and physical health outcomes. Optimism and pessimism were more similar in relation to psychological health than to other health-related behavior or physical health outcomes. However, a strongly interpretable pattern for the relation of optimism and pessimism to the health outcomes did not emerge. Further research may benefit from considering optimism and pessimism as bivariate and also should consider the conceptual components and behavioral mechanisms specific to each variable.     

Test anxiety,anxiety disorders,and school-related wellbeing: Manifestations of the same or different constructs?

Previous studies have shown that highly test anxious persons are more likely to meet criteria for an anxiety disorder and report more frequent symptoms of anxiety disorders than their low test anxious counterparts. However, it is unclear whether test anxiety should be treated as distinct to, or a manifestation of, anxiety disorders. Furthermore, the Dual Factor Model of Mental Health proposes that high subjective wellbeing cannot be solely inferred from the absence of psychopathology. To date, no studies have examined the Dual Factor Model in relation to test anxiety. In the present study, we examined how test anxiety, two common anxiety disorders (i.e., generalized anxiety disorder [GAD] and panic disorder [PD]), and subjective wellbeing in the school domain (i.e., school-related wellbeing) were related in a sample of 918 adolescents (M age = 15.77 years) using network analysis and latent profile analysis. Results from the network analysis indicated that test anxiety, GAD, PD, and school-related wellbeing were represented as distinct constructs. Bridge nodes were identified that linked test anxiety with GAD, PD, and school-related wellbeing. The latent profile analysis identified three of the four profiles predicted by the Dual Factor Model, including (a) troubled (i.e., low school-related wellbeing, high test anxiety, GAD, and PD), (b) complete mental health (i.e., high school-related wellbeing, low test anxiety, GAD, and PD), and (c) symptomatic but content (i.e., average school-related wellbeing, test anxiety, GAD, and PD). We concluded that test anxiety was distinct from, rather than a manifestation of, GAD and PD. We found support for the Dual Factor Model, albeit not unequivocal, using test anxiety as an additional indicator of psychopathology to that of GAD and PD.     

Concepts and categorization: do philosophers and psychologists theorize about different things?

Synthese - I discuss Edouard Machery’s claim that philosophers and psychologists when using the term ‘concept’ are really theorizing about different things. This view is not new,...     

Do the Concepts of Grammar and Use in Wittgenstein Articulate a Theory of Language or Meaning?

The paper elucidates Wittgenstein's later conception of philosophy as devoid of theories or theses, comprehending this as an articulation of a strategy for avoiding dogmatism in philosophy. More specifically, it clarifies Wittgenstein's conception by using what he says about the concepts of meaning and language as an example and by developing an interpretation that purports to make plain that what Wittgenstein says about these issues does not constitute a philosophical thesis. Adopting Wittgenstein's approach, we can, arguably, have a richer view of meaning and language than a commitment to philosophical theses allows for. I conclude with remarks on the method of analysis in terms of necessary conditions.     

Basic value orientations and moral foundations: Convergent or discriminant constructs?

This study examined the structural and genetic links between value orientations, based on the theory of basic values, and moral concerns, based on moral foundations theory. We hypothesized both structural and genetic convergence of Conservation (versus openness to change) with Binding foundations and of Self-transcendence (versus self-enhancement) with Individualizing foundations. We analyzed self- and informant ratings from 924 participants with extended multitrait-multirater modeling and ran twin model analyses on self-ratings from 555 twin pairs. For Conservation and Binding foundations, we found partial convergence across different rater perspectives and a substantial genetic overlap, but also distinct genetic factors. Self-transcendence and Individualizing foundations were found to be structurally divergent, but genetically linked. We discuss the conceptual and measurement-related implications of the findings.     

Influence of life event stress on physical illness: substantive effects or methodological flaws?

This study tests the hypothesis that the reported relationship between life event stress and physical illness is primarily a function of criterion and other content contamination in the stress measure. In particular, conventional life event measures include events related to physical health, which overlap with the criterion; events related to neuroticism, which influences the criterion; and events that are vague or subjective and could be affected by individual differences in psychological distress, response sets, and retrospective bias. In this study 386 adult males and females completed standard measures of life events and physical illness. Illness was significantly related to event subscales containing, respectively, health-related events, neuroticism-related events, and subjective events, but not to an "uncontaminated" event subscale. These results support the hypothesis of contamination and suggest that alternative approaches to the conceptualization and measurement of stress may need to be developed.     

To warn and to control: two distinct legal obligations or variations of a single duty to protect?

Prior to the Tarasoff decisions, jurisprudence pertaining to the duty to warn, or inform, to prevent violence to third persons, was separate from that pertaining to the duty to control to prevent such violence. The Tarasoff Principle consolidated preventive obligations in the face of foreseeable violence under a single "duty to protect." Even as courts adopted divergent rules for establishing foreseeability, many held to a single duty to protect with warnings as one possibility for fulfilling this option. Particularly over the past decade, courts have again disengaged the duty to warn and the duty to control, each requiring different legal predicates to occur. In recent years, courts have upheld or rejected a duty to warn, upheld or rejected a duty to control; and several courts have, within a single opinion, articulated fundamental distinctions between these two separate protective duties.     

Perceived causality and perceived force: Same or different?

Visually perceived interactions between objects, such as animated versions of billiard ball collisions, give rise to causal impressions, impressions that one object produces some effect in another, and force impressions, impressions that one object exerts a certain amount of force on another. In four experiments, evidence for strong divergence between these two impressions is reported. Manipulations of relative direction of motion and point of contact between the objects had different effects on the causal and force impressions (Experiment 1); delay between one object contacting another and the latter starting to move had a stronger effect on the causal impression than on the force impression (Experiment 2); a context of other moving objects significantly weakened the causal impression but not the force impression (Experiment 3); and there was an inverse relation between an impression of one object penetrating another and the amount of force the former was perceived as exerting on the latter (Experiment 4). These findings are explained in terms of differential effects of instructions on attention, and also in terms of differences in meaning between force and causality.     

Stuttering and fluency: Exclusive events or points on a continuum?

In recent years, several studies have been conducted in which the fluency of stutterers was compared with that of normal speakers. These investigations have been of two basic types, some involving objective measures of physiologic, aerodynamic, or acoustic features of the subjects' fluent speech signal, and others involving experiments performed in which listeners attempted to distinguish the fluency produced by stutterers from that generated by normal speakers. The body of literature pertaining to each of these two types of investigations is reviewed and interpreted. The interpretations offered are then developed in an effort to shed further light on both fluency and stuttering. Implications for further research, as well as for the evaluation, treatment, and post-therapy assessment of stutterers are drawn.     

Sexuality and attachment: a passionate relationship or a marriage of convenience?

The ubiquitous and persistent bodily urges of sexuality and their vicissitudes are explored in this paper, focusing on the complex relationship between libidinal desire and the attachment system, especially the latter's affect-regulating function. This complicated interrelationship is highlighted with clinical vignettes. Implications for transference and countertransference are explored in the discussion of affect regulation and its possible sexual entwining. Clinical data is presented to highlight the plasticity of sexuality. Sexuality's protean nature allows for a reassessment of the case of Little Hans, with emphasis on the unique interconnections between sexuality and the vital need for an attachment relationship. Stressing such interconnections raises important questions about the traditional concept of psychosexual stages.     

Drive for thinness and drive for muscularity: Opposite ends of the continuum or separate constructs?

The goal of this study was to examine whether the drive for thinness and the drive for muscularity occur concurrently among late adolescents and to understand the body attitudes associated with desiring a thinner and/or a more muscular physique. Participants included 235 college freshmen who participated in a larger study of body image and eating attitudes. The majority of individuals reported having both a high drive for thinness and a high drive for muscularity (65.4%). Additionally, the presence of both drives significantly predicted body compulsivity and body anxiety among females, and body-esteem among males. Results of the current study provide considerable evidence that a drive for thinness and a drive for muscularity are not mutually exclusive. Furthermore, the degree to which an individual strives for thinness and/or muscularity has differential effects on their body attitudes.     

Attacked by the gods or by mental illness? Hybridizing mental and spiritual health in Okinawa

In 1972, the reversion to Japanese rule brought with it many changes for Okinawans, among them the widespread introduction of psychiatry. Psychiatry was not well received at first due to the extensive presence of shamans, who had traditionally dealt with Okinawans’ spiritual and psychological afflictions. Both psychiatrists and shamans claimed to be able to heal those who were labelled ‘mentally ill’ or ‘mentally disordered’ by psychiatrists. This conflict between systems over the body of the patient/client is relevant to debates today about both the perceived value of generic mental health diagnosis and treatment regimes compared with indigenous healing,1 See Kleinman (, ); WHO (2001).  [Google Scholar] and the question of isolating how markers or symbols of identity are employed in patients’ help-seeking choices. We examine three cases from the 1970s of patients who were diagnosed as suffering from both schizophrenia and an indigenous condition known as kami daarii.     

Effects of subclinical depression and aging on generative reasoning about linear orders: same or different processing limitations?

The performance of older adults and depressed people on linear order reasoning is hypothesized to be best explained by different theoretical models. Whereas depressed younger adults are found to be impaired in generative inference making, older adults are well capable of making such inferences but exhibit problems with working memory (Experiments 1 and 2). Restriction of the available study time impairs reasoning by nondepressed control participants and. as such, proves to be a good model of older adults' but not depressed participants' limitations (Experiment 3). These results are replicated comparing depressed and older participants with a control group in the same study, providing increased power and linking the results to additional control measures of processing speed and working memory (Experiment 4).     

Seeing or smelling? Assessing personality on the basis of different stimuli

This study examines whether people can accurately assess personality on the basis of facial images and body odor and whether attractiveness influences these relationships. Three personality dimensions of target individuals – neuroticism, extraversion and dominance – were measured with the NEO Five-Factor Inventory, a one-item measure of dominance and the reports of close acquaintances. Naive observers assessed neuroticism and dominance at above-chance levels based on body odor, and they assessed extraversion (and in some cases, neuroticism) at above-chance levels based on either facial images alone or body odor and facial images presented together. The accuracy differed depending on the sex of the targets and the raters. In addition, facial and body odor attractiveness predicted the targets’ personalities and the assessments of their personalities. These results show that the accuracy of personality assessment changes when judges assess different types of stimuli.     

Modes of action of family interventions in depression and schizophrenia: the same or different?

The role of relatives' expressed emotion (EE) in mediating the efficacy of family interventions has been studied in randomized controlled trials (RCTs) involving people with schizophrenia and depression. Reanalysis of two RCTs (n=48) by Leff (1989) indicated that lowering relatives' EE and/or reducing social contact between the patient and family members accounted for the efficacy of the intervention for schizophrenia. However, this relationship has not been investigated previously with regard to depression, and this paper presents the results of a recent RCT which included measurement of EE and other possible mediating variables. In this study, amelioration of the critical attitude of the partner did not account for the superiority of couples therapy over antidepressant medication, since the same change occurred in the drug group. However, reducing the patient's exposure to the partner's hostility partially explained the efficacy of couples therapy. Further research on the process of change in families undergoing therapy is indicated to identify the variables that account for the efficacy of therapy.     

The effects of conversation on attention and peripheral detection: Is talking with a passenger and talking on the cell phone different?

In this study conversation with a remote person (hands-free phone), an in-vehicle person (passenger), and a no conversation (baseline) condition were compared on measures of attention and peripheral detection. We held conversation pace constant so that any difference found in attention or peripheral detection could be attributed to the distinctive feature of the type of conversation (remote, in-vehicle). The difficulty level of the verbal task was included as a second independent variable. Forty-eight undergraduate students participated in all conditions of a within-subjects design. The results revealed that conversation resulted in slower reactions and fewer correct responses on both attention and Peripheral Detection tasks compared to no conversation, while conversation type (remote/in-person) did not make a significant difference. Difficulty of the verbal task affected performance on the Peripheral Detection task but not on the attention task. These findings imply that conversation has a negative effect on attention and peripheral detection which are important components of driving. This effect may be greater with difficult conversations.
