Anticipatory pleasure predicts motivation for reward in major depression

Anhedonia, the lack of interest or pleasure in response to hedonic stimuli or experiences, is a cardinal symptom of depression. This deficit in hedonic processing has been posited to influence depressed individuals' motivation to engage in potentially rewarding experiences. Accumulating evidence indicates that hedonic processing is not a unitary construct but rather consists of an anticipatory and a consummatory phase. We examined how these components of hedonic processing influence motivation to obtain reward in participants diagnosed with major depression and in never-disordered controls. Thirty-eight currently depressed and 30 never-disordered control participants rated their liking of humorous and nonhumorous cartoons and then made a series of choices between viewing a cartoon from either group. Each choice was associated with a specified amount of effort participants would have to exert before viewing the chosen cartoon. Although depressed and control participants did not differ in their consummatory liking of the rewards, levels of reward liking predicted motivation to expend effort for the rewards only in the control participants; in the depressed participants, liking and motivation were dissociated. In the depressed group, levels of anticipatory anhedonia predicted motivation to exert effort for the rewards. These findings support the formulation that anhedonia is not a unitary construct and suggest that, for depressed individuals, deficits in motivation for reward are driven primarily by low anticipatory pleasure and not by decreased consummatory liking.     

An Investigation of Neuronal Integrity in Severe Paediatric Traumatic Brain Injury

Magnetic Resonance Spectroscopy (MRS) and its association with neuropsychological functioning was examined in the chronic injury phase of paediatric traumatic brain injury (TBI). Fifteen children, aged 10-16 years, with severe TBIs were compared with 15 controls, matched for age and gender. The TBI group was found to have significantly lower levels of N-acetyl aspartate (NAA) and Choline (Cho) in the right frontal lobe and generally displayed reduced performances on neuropsychological tests. A correlation between metabolites and reaction times was also obtained. Findings indicate a role of proton MRS as a measure of neuronal integrity following severe paediatric TBI and suggest a potential association of MRS with specific neuropsychological impairments.     

Joachim Wach's “Master and Disciple” Revisited: A Contemporary Symposium

Joachim Wach's classic 1924 treatment of two types of teaching and learning relationships is summarized by Professor Denny and commented on from three contemporary perspectives by three teaching scholars who raise the basic question, “Are Wach's models of student and disciple adequate for the nineties?” Following an introduction by Frederick M. Denny, the contributions presented are: I. Are Wach's Models of Student and disciple Adequate for the Nineties?, by Margaret R. Miles, II. Response to Joachim Wach's “Master and Disciple: Two Religio-Sociological Studies”: Buddhism, by Charles Hallisey and III. Wach and the Double Truth, by Earle H. Waugh.     

From cleaning up to helping out: Parental socialization and children's early prosocial behavior

Relations between parental socialization and infants’ prosocial behavior were investigated in sixty three 18- and 30-month old children. Parents’ socialization techniques (e.g., directives, negotiation, reasoning) differed for the two age groups, as did relations between socialization and different forms of emerging prosocial behavior (helping; sharing).     

WRITING THE HISTORY OF HISTORIED THOUGHT

Abstract: In Historied Thought, Constructed World , Joseph Margolis identifies the philosophical themes that will dominate philosophical discussions in the twenty-first century, given the recognition of the historicity of philosophical thought in the twentieth century. In what follows I examine these themes, especially cognitive intransparency, and the arguments presented in favor of them, noting the extent to which they rest on a view of language that takes a written text, and not speech, as the paradigm of language. I suggest if one takes speech as a mutual embodied action in a shared space as a model for language, the theme of cognitive intransparency—and the problems it brings in its wake—does not loom so large for those of us working in the history of philosophy. I conclude by showing that if we adopt this suggestion in relation to early Greek philosophy, that is, the period in the history of historied thought in which philosophy itself emerges as a linguistic and intellectual activity, we can better understand how and why philosophy emerged as it did—in the form of dialogues by Plato.     

The functional domain specificity of self-esteem and the differential prediction of aggression

On the basis of an evolutionary theory of self-esteem (SE), it was hypothesized that the SE-aggression relationship differs across functionally distinct domains of SE and across contexts. In 2 experiments, participants had the opportunity to aggress against the evaluator of an essay they had written. In Study 1, self-perceived superiority was positively related to aggression, whereas social inclusion was inversely related to aggression. In Study 2, in which the context was altered to simulate a mating competition, only a measure of self-perceived mate value emerged as a (positive) predictor of aggression. Global SE failed to contribute to the prediction of aggression in either experiment. Statistically controlling for narcissism did not eliminate either set of findings. Implications for the conceptualization and measurement of SE and narcissism are discussed.     

Aberrant Parasympathetic Stress Responsivity in Pure and Co-Occurring Major Depressive Disorder and Generalized Anxiety Disorder

Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) are highly comorbid; we know little, however, about the shared physiological features of these disorders. In the present study, we examined whether aberrant parasympathetic stress responsivity represents a transdiagnostic process in MDD, GAD, and co-occurring MDD-GAD. Adult women diagnosed with MDD only, GAD only, and co-occurring MDD-GAD and never-disordered controls (CTLs) completed a standardized laboratory task that involved anticipating, confronting, and recovering from a social stressor. Participants’ levels of respiratory sinus arrhythmia (RSA) were measured to index parasympathetic responses. The three clinical groups combined (participants with MDD only, GAD only, and co-occurring MDD-GAD) exhibited a similar pattern of RSA responsivity that differed significantly from that of the CTL group. Specifically, whereas CTL participants exhibited a sharp decrease in RSA when confronting the stressor and a sharp increase in RSA when recovering immediately following the stressor, the clinical participants exhibited a blunted response pattern that involved weaker fluctuations in RSA when confronting and recovering from the stressor. There were no significant differences among the three clinical groups in RSA responses. Interestingly, clinical and CTL participants did not differ in self-reported fluctuations in negative emotional arousal. Finally, for clinical participants patterns of RSA reactivity to the acute stressor were associated differentially with trait rumination and worry as maladaptive forms of emotion regulation. These findings support the formulation that aberrant parasympathetic stress responsivity is a shared feature of MDD, GAD, and co-occurring MDD-GAD that is characterized by diminished reactivity to and recovery from stress.     

Development and Validation of Personality Disorder Spectra Scales for the MMPI–2–RF

The purpose of this study was to develop and validate a set of MMPI–2–RF (Ben-Porath &; Tellegen, 2008/2011) personality disorder (PD) spectra scales. These scales could serve the purpose of assisting with DSM–5 PD diagnosis and help link categorical and dimensional conceptions of personality pathology within the MMPI–2–RF. We developed and provided initial validity results for scales corresponding to the 10 PD constructs listed in the DSM–5 using data from student, community, clinical, and correctional samples. Initial validation efforts indicated good support for criterion validity with an external PD measure as well as with dimensional personality traits included in the DSM–5 alternative model for PDs. Construct validity results using psychosocial history and therapists' ratings in a large clinical sample were generally supportive as well. Overall, these brief scales provide clinicians using MMPI–2–RF data with estimates of DSM–5 PD constructs that can support cross-model connections between categorical and dimensional assessment approaches.     

Beliefs About Poverty and Opportunity Among Mexican Immigrant Farm Workers1

This study examined attributions for poverty and beliefs about upward mobility among 124 Mexican immigrant farm workers. The effects of gender and length of United States residency were also analyzed. Despite living in poverty and perceiving racism as a significant problem, respondents expected upward mobility for themselves and their children. Consistent with previous research on low‐income and ethnic minority attributions (Bullock, 1999; Hunt, 1996; Kluegel & Smith, 1986), structural explanations for poverty were favored over individualistic causes, however, considerable support for individualistic causes was also expressed. Gender and length of residency were not predictive of immigrants’ beliefs about poverty. Implications for future research are discussed.
