Assessing general maladjustment with the MMPI-2

The validities of 7 MMPI-2 (Butcher, Graham, Ben-Porath, Tellegen, & Kaemmer, 2001) measures of general maladjustment were compared using a composite criterion measure based on self-reported symptom severity and clinicians' ratings of symptom severity and level of functioning. Participants were 274 male and 425 female clients at a community mental health center and 105 male and 247 female clients at a university psychological clinic. All MMPI-2 measures were significantly related to the composite criterion measure for both male and female clients in both settings. The mean score on 8 clinical scales (M8) consistently was the best indicator of maladjustment. Although other MMPI-2 measures sometimes added significantly to the variance accounted for in the criterion measure, increments were small and probably not clinically meaningful. However, M8 added significantly and meaningfully to each of the other MMPI-2 measures in predicting maladjustment. Implications for using the MMPI-2 to assess general maladjustment in outpatient mental health settings are discussed.

Auditory frequency discrimination in adult developmental dyslexics

Developmental dyslexics reportedly discriminate auditory frequency poorly. A recent study found no such deficit. Unlike its predecessors, however, it employed multiple exposures per trial to the standard stimulus. To investigate whether this affects frequency discrimination in dyslexics, a traditional two-interval same-different paradigm (2I_1A_X) and a variant with six A-stimuli per trial (2I_6A_X) were used here. Frequency varied around 500 Hz; interstimulus interval (ISI) ranged between 0 and 1,000 msec. Under 2I_1A_X, dyslexics always had larger just noticeable differences (JNDs) than did controls. Dyslexic and control JNDs were equal at shorter ISIs under 2I_6A_X, but dyslexics became worse than controls at longer ISIs. Signal detection analysis suggests that both sensory variance and trace variance are larger in dyslexics than in controls.     

Effects of financial incentives on the breakdown of mutual trust

Disagreements between psychologists and economists about the need for and size of financial incentives continue to be hotly discussed. We examine the effects of financial incentives in a class of interactive decision-making situations, called centipede games, in which mutual trust is essential for cooperation. Invoking backward induction, the Nash equilibrium solution for these games is counterintuitive. Our previous research showed that when the number of players in the centipede game is increased from two to three, the game is iterated in time, the players are rematched, and the stakes are unusually high, behavior approaches equilibrium play. Results from the present study show that reducing the size of the stakes elicits dramatically different patterns of behavior. We argue that when mutual trust is involved, the magnitude of financial incentives can induce a considerable difference.     

AFFECT IN PSYCHOANALYTIC THEORY: DISCUSSION OF ANDRÉ GREEN'S “ON DISCRIMINATING AND NOT DISCRIMINATING BETWEEN AFFECT AND REPRESENTATION”1

André Green's 1999 programmatic essay on affect and representation, an attempt to extend Freud's model of the neuroses (where affect and representation have different vicissitudes) to non‐neurotic cases is submitted to critical reading. Green wishes to restore the importance of representation; to use the second topographical theory, where id, psychical impulse and object‐cathexis replace the unconscious and the ideational representation in order to conceptualise borderline disturbance, and to show how ultimately the ‘non‐discrimination’ affect‐representation obtains in non‐neurotic cases as well. The author, interested in the question posed in Green's essay as to what we have to sell our borderline patients, addresses the various reasons why this project fails. Among the problematic points are the paradox of Green's model of unconscious affect, that does not allow the analyst to generate meaning with borderline patients, the view of ‘representation’ as replacing presence and perception of the object that does not allow the analyst to be a nonabsent object, and the inabilty to conceptualise affect‐representatives and to work out the definition of affect as ‘the anticipation of a meeting with the other's body’ which does not allow the analyst to function as an ‘anticipatory object’ or ‘an object of affect’.     

Infant responsiveness and maternal confidence in the neonatal period

Responsiveness in prematurely and term-born infants was studied cross-sectionally in relation to maternal confidence. Orientation and arousal were measured in 140 prematurely (mean BW 1,398 g, GA 30.1 weeks) and 75 term-born infants (mean BW 3,613 g, GA 39.3 weeks) with the Neonatal Behavioral Assessment Scales. Mothers filled out the Maternal Confidence Questionnaire and a modified version of the Parenting Stress Index. Prematurely born infants had a significantly lower level of arousal than term-born neonates. Responsiveness was not associated with maternal confidence. Lower confidence was associated with primiparity in both groups of mothers. Multiparous mothers of prematurely born infants had significantly lower levels of confidence than multiparous mothers of term-born infants. Confidence was significantly associated with stress for mothers of prematurely and term-born infants, and may be focused in follow-up after giving birth. Prematurely born infants should be examined more thoroughly in aspects of arousal at the time of discharge.     

Coping styles and personality: a biometric analysis

Previous research suggests that coping styles are modestly heritable and that this genetic influence is shared in large part with genetic influences on personality. To test this hypothesis, we estimated the heritable basis of the Coping Inventory for Stressful Situations in a sample of 91 monozygotic and 80 dizygotic twin pairs. Task-oriented, emotion-oriented, and social diversion coping styles were modestly heritable (h(2)=.17 to .20), whereas the use of distraction appeared to be influenced solely by environmental factors. Multivariate analyses showed that genetic contributions to coping styles were, at best, only modestly related to genetic contributions to personality (r=-.03 to .35). Environmental contributions to personality were unrelated to environmental factors in coping style. These results suggest that coping style is not merely a manifestation of basic personality traits but does support the possibility that the genetic factors in personality influences have a modest influence on an individual's preferred coping style or strength (e.g., rigidity vs flexibility).     

Opioids: from physical pain to the pain of social isolation

The opioid systems play an important role in mediating both physical pain and negative affects (eg, the pain of social isolation). From an evolutionary perspective, it is not surprising that the neurocircuitry and neurochemistry of physical pain would overlap with that involved in complex social emotions. Exposure to trauma as well as a range of gene variants in the opioid system may be associated with alterations in opioid systems function, with changes in reward processing, and with vulnerability to substance abuse. A role for interventions with opioid agents in depression and anxiety disorders has been suggested.
