High-quality work,job satisfaction,and occupational injuries

The authors investigated whether and how 1 element of a high-performance work system, namely high-quality jobs (composed of extensive training, variety, and autonomy), affects occupational injuries. On the basis of data from the Australian WIRS95 database (N = 16,466; Department of Workplace Relations and Small Business, 1997), high-quality jobs exerted a direct effect on injuries and an indirect effect through the mediating influence of job satisfaction. Conceptual, methodological, and practical issues are discussed.     

Legislative warriors: American psychiatrists,psychologists, and competing claims over psychotherapy in the 1950s

American psychiatrists and psychologists have long been close colleagues and fierce rivals. There is no better illustration of this polarized relationship than the chronic tug-of-war over psychotherapy. Both groups laid claim to psychotherapy-whatever it was and however it was practiced. Psychiatrists attempted to monopolize psychotherapy despite its ambiguous status as an essential component of the healing arts. After the war, psychologists pressed for a share on the basis of their qualifications and competence, but struggled to overcome the limitations imposed by medical envy. This story lays bare the crucial function of tools and techniques for defining the identity and the boundaries of a science-based profession.     

The structure of child and adolescent psychopathology: generating new hypotheses

To begin to resolve conflicts among current competing taxonomies of child and adolescent psychopathology, the authors developed an interview covering the symptoms of anxiety, depression, inattention, and disruptive behavior used in the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994), the International Statistical Classification of Diseases and Related Health Problems (ICD-10; World Health Organization, 1992), and several implicit taxonomies. This interview will be used in the future to compare the internal and external validity of alternative taxonomies. To provide an informative framework for future hypothesis-testing studies, the authors used principal factor analysis to induce new testable hypotheses regarding the structure of this item pool in a representative sample of 1,358 children and adolescents ranging in age from 4 to 17 years. The resulting hypotheses differed from the DSM-IV, particularly in suggesting that some anxiety symptoms are part of the same syndrome as depression, whereas separation anxiety, fears, and compulsions constitute a separate anxiety dimension.     

Emotional Knowing: the Role of Embodied Feelings in Affective Cognition

The emotions play a crucial role in our apprehension of meaning, value, or significance — and their felt quality is intimately related to the sort of awareness they provide. This is exemplified most clearly by cases in which dispassionate cognition is cognitively insufficient, because we need to be emotionally agitated in order to grasp that something is true. In this type of affective experience, it is through a feeling of being moved that we recognize or apprehend that something is the case. And that is why our emotions are epistemically indispensable: namely, because they give us access to significant truths. In this essay, I explain how the phenomenally felt character of an emotion is intimately linked with its intentionality. Intellectual activity divorced from affective feeling is profoundly lacking — not only in its qualitative feel, but also in its epistemic import, or its ability to inform us about matters of significance. A better appreciation of how the living body is involved in affective experience should help us to understand the distinctive kind of embodied cognition that emotional responses involve. It also ought to resolve confusions about phobic responses and other “recalcitrant” emotions, which are not divorced from cognition as many have claimed.     

On the (In)Validity of Tests of Simple Mediation: Threats and Solutions

Mediation analysis is a popular framework for identifying underlying mechanisms in social psychology. In the context of simple mediation, we review and discuss the implications of three facets of mediation analysis: (a) conceptualization of the relations between the variables, (b) statistical approaches, and (c) relevant elements of design. We also highlight the issue of equivalent models that are inherent in simple mediation. The extent to which results are meaningful stem directly from choices regarding these three facets of mediation analysis. We conclude by discussing how mediation analysis can be better applied to examine causal processes, highlight the limits of simple mediation, and make recommendations for better practice.     

Multimethod Assessment of Psychopathology Among DSM-IV Subtypes of Children With Attention-Deficit/Hyperactivity Disorder: Self-, Parent, and Teacher Reports

Using data based on self-, parent, and teacher reports, we assessed various aspects of psychopathology in a large sample of control children and those with ADHD. Confirmatory factor analysis was employed to extract response bias from latent constructs of aggression, anxiety, attention problems, depression, conduct disorder, and hyperactivity. These latent constructs were then entered into logistic regression equations to predict membership in control versus ADHD groups, and to discriminate between ADHD subtypes. Results of the regression equations showed that higher levels of attention problems and aggression were the best predictors of membership in the ADHD group relative to controls. Logistic regression also indicated that a higher degree of aggression was the only significant predictor of membership in the ADHD-Combined group compared to the ADHD-Inattentive group. However, when comorbid diagnoses of Oppositional Defiant Disorder and Conduct Disorder were controlled for in the logistic regression, greater hyperactivity rather than aggression was the sole variable with which to distinguish the ADHD-Combined from the ADHD-Inattentive subtype. Results are discussed in the context of the DSM-IV ADHD nosology and the role of instrument and source bias in the diagnosis of ADHD.     

Relations between implicit and explicit measures of attitudes and measures of behavior: evidence of moderation by individual difference variables

The moderating role of individual difference variables (Self-Reported Habit Index [SRHI], Need for Cognition [NFC]) on relationships between implicit (Implicit Association Test [IAT], Extrinsic Affective Simon Test [EAST]) or explicit measures of attitude and behavior is assessed in two studies. A dissociation pattern is found on self-report diary measures of behavior. In Study 1, the EAST-behavior relationship is moderated by SRHI; explicit measures of the attitude-behavior relationship are moderated by NFC. In Study 2, the IAT-behavior relationship is moderated by SRHI; explicit measures of the attitude-behavior relationship are moderated by NFC. Higher levels of SRHI and NFC are associated with stronger relationships between the implicit or explicit measures of attitude and the measure of behavior. In Study 2, the SRHI x IAT interaction is replicated for an objective behavior measure. Implications for understanding the relationship between implicit and explicit measures of attitudes and measures of behavior are discussed.     

Tracking the continuity of language comprehension: computer mouse trajectories suggest parallel syntactic processing

Although several theories of online syntactic processing assume the parallel activation of multiple syntactic representations, evidence supporting simultaneous activation has been inconclusive. Here, the continuous and non-ballistic properties of computer mouse movements are exploited, by recording their streaming x, y coordinates to procure evidence regarding parallel versus serial processing. Participants heard structurally ambiguous sentences while viewing scenes with properties either supporting or not supporting the difficult modifier interpretation. The curvatures of the elicited trajectories revealed both an effect of visual context and graded competition between simultaneously active syntactic representations. The results are discussed in the context of 3 major groups of theories within the domain of sentence processing.
